To do this, we participated as volunteers in the HistoryCal project. We used the case study research method to investigate technique application and community participation. We identified adverse conditions that were an obstacle to technique application and modified the technique to make it applicable.

A business model perspective}, Journal = {JOURNAL OF ENTERPRISE INFORMATION MANAGEMENT}, Year = {2017}, Volume = {30}, Number = {4}, Pages = {534-554}, Abstract = {Purpose - Open Source software companies (OSSCs) are confronted with institutional pressures from Open Source software (OSS) communities. They must find an acceptable balance between the expectations of these communities and their own business model. However, there are still few studies that try to analyse the OSSC business models. The purpose of this paper is to highlight OSSC typical business models by using rich empirical data. Design/methodology/approach - The methodology is based on a combination of quantitative analysis of a sample of 66 OSSCs and qualitative analysis of three typical situations resulting from that sample. Findings - The quantitative study enables the authors to highlight three typical business models. The in-depth study of three typical cases enables the authors to specify these OSSC business models. The authors can distinguish four key dimensions: the relationship developed with the OSS communities, the strategic manoeuvres made, the key resources and competitive positioning. Research limitations/implications - The results indicate that it is possible for firms to accommodate both profit and non-profit logics using different strategic manoeuvres to position themselves with regard to the Open Source institutional environment. Such accommodation requires the development of key resources and the adoption of suitable competitive positioning. Practical implications - This study allows the authors to highlight two main practical contributions for OSSCs' directors. First, the different manoeuvres identified may help them to ensure coherence between their strategic choices and the business model chosen. Second, the results can help OSSC founders identify value creation mechanisms more clearly by analysing four key variables. Originality/value - This paper provides new insight about OSSCs business models. It aggregates four dimensions that provide a more ``fine-grained{''} analysis of business models, while other studies often emphasise one dimension (usually the regime of appropriability).}, DOI = {10.1108/JEIM-05-2015-0041}, ISSN = {1741-0398}, EISSN = {1758-7409}, Unique-ID = {WOS:000406637900001}, } @article{ WOS:000343343100006, Author = {Reisinger, Markus and Ressner, Ludwig and Schmidtke, Richard and Thomes, Tim Paul}, Title = {Crowding-in of complementary contributions to public goods: Firm investment into open source software}, Journal = {JOURNAL OF ECONOMIC BEHAVIOR \& ORGANIZATION}, Year = {2014}, Volume = {106}, Pages = {78-94}, Month = {OCT}, Abstract = {We present a fairly general model in which firms are competitors in a commercial market segment and can invest into a complementary public good like open source software. We show that, contrary to standard predictions, additional contribution to the public good by the government or a new market entrant can lead to higher investments of all incumbent firms, that is, a crowding-in effect. This result occurs if the investment cost function is superadditive. We find that government contribution leads to larger crowding-in effects than subsidizing market entry if the price elasticity of demand with respect to the private good is large relative to the one with respect to the public good. Our results are robust to extensions in the timing and the mode of competition. (C) 2014 Elsevier B.V.

Nuisance attribute projection (NAP) and factor analysis (FA) are examined and shown to provide significant improvements. For FA, a new symmetrical scoring (SFA) approach is proposed.

Governments and organizations are beginning to adopt OSS on a large scale and several governmental initiatives have encouraged the use of OSS in the private sector. One major issue for the government and private sector is the selection of appropriate OSS. This paper uses new internal quality characteristics for selecting OSS that can be added to the dimensions of DeLone and McLean information systems' model. Through this study, the quality characteristics are organized in a two level hierarchy, which list characteristics and sub-characteristics that are interconnected with three main dimensions: system quality, information quality and service quality. These characteristic dimensions are tailored to the criteria having been built from literature study and standard for software quality and guidelines. This paper presents case study results of applying the proposed quality characteristic on eight different open source software that are divided between open source network tools and learning management systems.

However, with the emergence of new environmental design tasks, addressing all possible use cases and tasks is challenging and cannot be covered by a single tool. Urban-scale analysis at this level of complexity often requires linking multiple emerging tools, rather than using a single tool, to adequately evaluate a variety of possible fields in urban environmental design. To achieve this, flexible platforms are needed to support multiple input formats (e.g., geometric and non-geometric building properties), enabling the mapping of such inputs to underlying simulation engines. This paper provides an overview of the open-source URBANopt Software Development Kit (SDK) for modeling high-performance buildings and energy systems at a district scale. URBANopt's flexible SDK is composed of several modules that can be customized to integrate with other tools and generate new workflows to perform urban environmental design tasks, such as capturing interactions between individual buildings, district energy systems, distributed energy resources, and the electric distribution grid. We describe the functionality of the core SDK modules in URBANopt (called Core Gem, GeoJSON Gem, and Scenario Gem) and discuss the flexibility of these modules as a means of integration with a variety of tools. We also document and demonstrate technical details of writing and combining new modules to create customized workflows. Finally, we present a case study that uses the URBANopt SDK to model a hypothetical mixed-use urban project and simulate various scenarios to meet district energy performance goals.}, ISSN = {2574-6308}, ResearcherID-Numbers = {Long, Nicholas/U-6160-2017}, Unique-ID = {WOS:001150368100035}, } @article{ WOS:000267233300003, Author = {Janamanchi, Balaji and Katsamakas, Evanyelos and Raghupathi, Wullianallur and Gao, Wei}, Title = {The State and Profile of Open Source Software Projects in health and medical informatics}, Journal = {INTERNATIONAL JOURNAL OF MEDICAL INFORMATICS}, Year = {2009}, Volume = {78}, Number = {7}, Pages = {457-472}, Month = {JUL}, Abstract = {Purpose: Little has been published about the application profiles and development patterns of open source software (OSS) in health and medical informatics. This study explores these issues with an analysis of health and medical informatics related OSS projects on SourceForge, a large repository of open source projects. Methodology: A search was conducted on the SourceForge website during the period from May 1 to 15, 2007, to identify health and medical informatics OSS projects. This search resulted in a sample of 174 projects. A Java-based parser was written to extract data for several of the key variables of each project. Several visually descriptive statistics were generated to analyze the profiles of the OSS projects. Results: Many of the projects have sponsors, implying a growing interest in OSS among organizations. Sponsorship, we discovered, has a significant impact on project success metrics. Nearly two-thirds of the projects have a restrictive license type. Restrictive licensing may indicate tighter control over the development process. Our sample includes a wide range of projects that are at various stages of development (status). Projects targeted towards the advanced end user are primarily focused on bio-informatics, data formats, database and medical science applications. Conclusion: We conclude that there exists an active and thriving OSS development community that is focusing on health and medical informatics. A wide range of OSS applications are in development, from bio-informatics to hospital information systems. A profile of OSS in health and medical informatics emerges that is distinct and unique to the health care field. Future research can focus on OSS acceptance and diffusion and impact on cost, efficiency and quality of health care. (C) 2009 Elsevier Ireland Ltd.

Each of these tools typically excels at one type of analysis, such as of microarrays, of metabolic networks and of predicted protein structure. A crucial challenge is to combine the capabilities of these (and other forthcoming) data resources and tools to create a data exploration and analysis environment that does justice to the variety and complexity of systems biology data sets. A solution to this problem should recognize that data types, formats and software in this high throughput age of biology are constantly changing. Results: In this paper we describe the Gaggle -a simple, open-source Java software environment that helps to solve the problem of software and database integration. Guided by the classic software engineering strategy of separation of concerns and a policy of semantic flexibility, it integrates existing popular programs and web resources into a user-friendly, easily-extended environment. We demonstrate that four simple data types (names, matrices, networks, and associative arrays) are sufficient to bring together diverse databases and software. We highlight some capabilities of the Gaggle with an exploration of Helicobacter pylori pathogenesis genes, in which we identify a putative ricin-like protein -a discovery made possible by simultaneous data exploration using a wide range of publicly available data and a variety of popular bioinformatics software tools. Conclusion: We have integrated diverse databases (for example, KEGG, BioCyc, String) and software (Cytoscape, DataMatrixViewer, R statistical environment, and TIGR Microarray Expression Viewer). Through this loose coupling of diverse software and databases the Gaggle enables simultaneous exploration of experimental data (mRNA and protein abundance, protein-protein and protein-DNA interactions), functional associations (operon, chromosomal proximity, phylogenetic pattern), metabolic pathways (KEGG) and Pubmed abstracts (STRING web resource), creating an exploratory environment useful to `web browser and spreadsheet biologists', to statistically savvy computational biologists, and those in between.

We derive a model from extant research and refine it through the study of three inter-organisational networks. The findings reveal how a firm's ability to access a value network of complementors is crucial for effective value creation and capture. Two types of networks are evident: a high-density network of familiar partners and a low-density network of multiple, often unfamiliar, partners. Leveraging these networks depends on the level of commitment, volume of knowledge exchange and the alignment of objectives among participant firms. Effective governance is revealed as critical for creating and capturing value within both types of network; and depends on both formal and informal mechanisms.}, DOI = {10.1057/ejis.2012.44}, ISSN = {0960-085X}, EISSN = {1476-9344}, ORCID-Numbers = {Feller, Joseph/0000-0001-9335-4542}, Unique-ID = {WOS:000323550500006}, } @article{ WOS:000276642200007, Author = {Hall, G.

Their fate can be predicted using reactive transport models that describe reaction and advective and dispersive movement of these components in their natural environment. Recently a number of software packages have been implemented in the open source software R that allow one to implement reactive transport models. Central to this is the ReacTran R-package, a comprehensive collection of functions for modeling reactive components that may be distributed over multiple phases, whose dynamics are coupled through biological and geochemical reactions, and that are transported in one-, two- or three-dimensional domains with simple geometries. Dedicated solution methods are in R-packages deSolve and rootSolve. The modeling packages facilitate the simulation of reaction and transport of components for spatial scales ranging from micrometers to kilometers and spanning multiple time-scales. As they are influenced in similar ways, the same functions can solve biogeochemical models of the sediment, groundwater, rivers, estuaries, lakes or water columns, experimental setups, or even describe reaction and transport within flat, cylindrical or spherical bodies, such as organisms, aggregates, or the dispersion of individuals on flat surfaces and so on. We illustrate the use of R for reactive transport modeling by three applications spanning several orders of magnitude with respect to spatial and temporal scales. They comprise (1) a model of an experimental flow-through sediment reactor, where fitting so-called breakthrough curves are used to derive sulfate reduction rates in an estuarine sediment, (2) a conservative and reactive tracer addition experiment in a small stream, which implements the concept of river spiraling, and (3) a 2-D and 3-D model that describes oxygen dynamics in the upper layers of the sediment, interspersed with several hotspots of increased reaction intensities. The packages ReacTran, deSolve and rootSolve are implemented in the software R and thus available for all popular platforms (Linux, Windows, Mac). Models implemented using this software are short and easily readable, yet they are efficiently solved. This makes R extremely well suited for rapid model prototyping. (C) 2011 Elsevier Ltd.

If the context in which free and open source software tools are created and employed is examined, it becomes clear that: the sustainability of any software (FOSS, custom or commercial) to ensure the preservation of the digital heritage will depend on careful assessment of, and provision for, the costs (implicit and explicit) entailed in the production and continued employment of these tools. The purpose of this paper is to focus on FOSS and archiving of the digital heritage. Design/methodology/approach - Portico, a not-for-profit digital preservation service, explores the costs of FOSS based on its experiences as a working archive with an extremely long time horizon. Findings - There are considerable benefits to FOSS, including its openness and the broad-based testing of it in real-world situations. FOSS tools can provide considerable cost savings over proprietary tools. However, FOSS is neither free to use, nor to create, nor to maintain. Digital preservation organizations must inventory not only the FOSS tools in the preservation arsenal, but the network of sustaining tools (FOSS and otherwise), documentation, and ``tribal knowledge{''} that make these tools effectively usable. The risks to sustainability of this network of resources must be assessed, and determine what it will cost to keep them viable. Strategies will have to be considered and implemented for providing the means to sustain these resources. An engaged community of use is the best guarantor of the vitality of any FOSS tool. As that community wanes, it becomes even more essential to capture the significant properties and domain knowledge about that tool. Creators of new software in the digital preservation space have a particular obligation to provide and maintain information about the significant properties of that software. Originality/value - The paper shows how Portico brings its practical experiences integrating multiple FOSS tools to bear on an analysis of the costs to creating and maintaining these tools over the long-term.}, DOI = {10.1108/07378831011047622}, ISSN = {0737-8831}, ORCID-Numbers = {Morrissey, Sheila/0000-0003-2069-1219}, Unique-ID = {WOS:000285526500003}, } @article{ WOS:000253288100003, Author = {Koch, Stefan and Neumann, Christian}, Title = {Exploring the effects of process characteristics on product quality in open source software development}, Journal = {JOURNAL OF DATABASE MANAGEMENT}, Year = {2008}, Volume = {19}, Number = {2}, Pages = {31-57}, Month = {APR-JUN}, Abstract = {There has been considerable discussion on the possible impacts of open source software development practices, especially in regard to the quality of the resulting software product. Recent studies have shown that analyzing data from source code repositories is an efficient way to gather information about project characteristics and programmers, showing that OSS projects are very heterogeneous in their team structures and software processes. However, one problem is that the resulting process metrics measuring attributes of the development process and of the development environment do not give any hints about the quality, complexity, or structure of the resulting software. Therefore, we expanded the analysis by calculating several product metrics, most of them specifically tailored to object-oriented software. We then analyzed the relationship between these product metrics and process metrics derived from a CVS repository. The aim was to establish whether different variants of open source development processes have a significant impact on the resulting software products. In particular we analyzed the impact on quality and design associated with the numbers of contributors and the amount of their work, rising the GINI coefficient as a measure of inequality within the developer group.}, DOI = {10.4018/jdm.2008040102}, ISSN = {1063-8016}, ResearcherID-Numbers = {Koch, Stefan/B-8548-2017}, ORCID-Numbers = {Koch, Stefan/0000-0001-5959-3208}, Unique-ID = {WOS:000253288100003}, } @inproceedings{ WOS:000516788300093, Author = {Razzaq, Seher and Xie, Min}, Editor = {Khatri, SK and Rana, A and Kapur, PK}, Title = {Understanding the Surviving Bugsin Open Source Software through the Community Perspective: Using Bayesian Analysis}, Booktitle = {PROCEEDINGS 2019 AMITY INTERNATIONAL CONFERENCE ON ARTIFICIAL INTELLIGENCE (AICAI)}, Year = {2019}, Pages = {494-498}, Note = {Amity International Conference on Artificial Intelligence (AICAI), Amity Univ Dubai, Dubai, U ARAB EMIRATES, FEB 04-06, 2019}, Organization = {Amity Univ Uttar Pradesh, Amity Inst Informat Technol; IEEE UAE Sect}, Abstract = {Mining thesoftware repositories expose a lot of factors for software quality improvement.

We propose a socio-technical pattern that can be used to locate emerging coordination problems in Open Source projects. With the help of our tool and method called TESNA, we demonstrate a method to monitor the socio-technical core-periphery movement in Open Source projects. We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project. Such an analysis can provide developers with a good insight into the health of an Open Source project. Researchers can gain from the pattern theory, and from the method we use to study the core-periphery movements.

This study also investigates the views, satisfaction level and challenges of librarians in the adoption and use of IR software. Design/methodology/approach A survey was conducted to collect data from the Library Information Science (LIS) professionals working in the university libraries of Islamabad. Data were collected from all library professionals of the Islamabad university libraries by using a structured questionnaire. Out of the total 104 LIS professionals, 84 participated in the study with a response ratio of 80.76\%. Findings The findings disclose that out of 23 universities recognized by Higher Education Commission (HEC) in Islamabad, 17 (public and private) have developed IRs. Currently, university libraries that have fully implemented the IRs are less as compared with those universities that have partially implemented IR software. However, a good number of university libraries are in the process to develop IRs. Free and open-source software is being used mostly in libraries as compared with in-house developed, locally developed or commercial software. The opinion of librarians about using IR software expressed a positive attitude of librarians. Some of the major challenges encountered by the librarians in using open-source IR software include selection of suitable software and materials for digitization, lack of cooperation from the parent organization, inadequate training opportunities and lack of skilled staff. Research limitations/implications This study is geographically limited to the university libraries in Islamabad. Practical implications This study will encourage the Pakistani LIS professionals to use open-source software for the development of IRs in their libraries. Originality/value This study concludes that the development of IRs in university libraries is a need of the hour. Although the launching of IRs requires certain skills and competencies, Pakistani librarians can overcome these challenges by mastering the ICT skills.}, DOI = {10.1108/IDD-10-2021-0113}, EarlyAccessDate = {MAY 2022}, ISSN = {2398-6247}, ResearcherID-Numbers = {Khan, Muhammad Kabir/ACU-7391-2022}, ORCID-Numbers = {Khan, Muhammad Kabir/0000-0002-8295-0338}, Unique-ID = {WOS:000793013000001}, } @article{ WOS:000301630700012, Author = {Shirazi, Farid}, Title = {Free and Open Source Software versus Internet content filtering and censorship: A case study}, Journal = {JOURNAL OF SYSTEMS AND SOFTWARE}, Year = {2012}, Volume = {85}, Number = {4}, Pages = {920-931}, Month = {APR}, Abstract = {This study critically investigates the main characteristics and features of anti-filtering packages provided by Free and Open Source Software (FOSS). For over a decade, the digital communities around the globe have used FOSS packages not only as an inexpensive way to access to information available on Internet, but also to disseminate thoughts, opinions and concerns about various socio-political and economic matters. Proxy servers and FOSS played a vital role in helping citizens in repressed countries to bypass the state imposed Internet content filtering and censorship practices. On the one hand, proxy servers act as redirectors to websites, and on the other hand, many of these servers are the main source for downloading FOSS anti-filtering software packages. These packages can provide secure web surfing via anonymous web access, data encryption. IP address masking, location concealment, browser history and cookie clean-ups but they also provide proxy software updates as well as domain name updates. The main objectives of this study are to investigate the role of FOSS packages in combating Internet content filtering and censorship and empowering citizens to effectively participate in communication discourse. By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In particular, they are poorly adapted to the slow Internet connections in many developing countries such as Iran. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net. Therefore, this study offers a new model that takes into account not only the existing level of the Internet infrastructure but also the growing number of Internet users demanding more effective FOSS packages for faster access to uncensored information while maintaining anonymity.

In particular, we investigate how personality traits namely psychological needs for autonomy and competence, and one's altruism interact with motivations. Following Self-Determination Theory, we differentiate types of motivation in OSS communities. In addition, drawing upon the Affective Event theory, we submit that personality traits moderate the relationships between task effort and both external and identified motivations.

A systematic literature review (SLR) is employed for the identification of potential risk factors in OSS whereas questionnaire survey is used to validate the findings of the SLR from the relevant expert community. In the second round another SLR is carried out to identify the practices for softening the effect of risk-factors in OSS development.

Amid the risk factors identified bugs, insufficient product documentation, and lack of communication and coordination among developers are considered the most important Further, we performed a secondary SLR to identify the practices for mitigating the effects of the risk factors in OSS. Therefore, a total of 31 practices for mitigating and addressing the risk factors in OSS were identified. In this work, we identified 14 risk factors and 31 practices for mitigating the critical risk factors, through SLR for adapting OSS development from developers' perspectives.

However, it has also brought important IT security risks that are impacting the OSS IT adoption decision-making process. The recent Heartbleed bug demonstrated the grandeur of the issue. While much of the noise relates to the amplification of perceived risks by the popular mass media coverage, the effect is that many enterprises, mainly for risk reasons, have still chosen not to adopt OSS.

Software documentation for these libraries is crucial in helping programmers/analysts know what libraries are available and how to use them. Yet documentation for open source software libraries is widely considered low-quality. This article is a collaboration between CSCW researchers and contributors to data analytics OSS libraries, based on ethnographic fieldwork and qualitative interviews. We examine several issues around the formats, practices, and challenges around documentation in these largely volunteer-based projects. There are many different kinds and formats of documentation that exist around such libraries, which play a variety of educational, promotional, and organizational roles. The work behind documentation is similarly multifaceted, including writing, reviewing, maintaining, and organizing documentation. Different aspects of documentation work require contributors to have different sets of skills and overcome various social and technical barriers. Finally, most of our interviewees do not report high levels of intrinsic enjoyment for doing documentation work (compared to writing code). Their motivation is affected by personal and project-specific factors, such as the perceived level of credit for doing documentation work versus more `technical' tasks like adding new features or fixing bugs. In studying documentation work for data analytics OSS libraries, we gain a new window into the changing practices of data-intensive research, as well as help practitioners better understand how to support this often invisible and infrastructural work in their projects.}, DOI = {10.1007/s10606-018-9333-1}, ISSN = {0925-9724}, EISSN = {1573-7551}, ResearcherID-Numbers = {Geiger, R./AAV-4309-2021 Holdgraf, Christopher/M-7134-2015}, ORCID-Numbers = {Geiger, R.Stuart/0000-0001-7215-0532 varoquaux, Nelle/0000-0002-8748-6546 Holdgraf, Christopher/0000-0002-2391-0678}, Unique-ID = {WOS:000441232100016}, } @inproceedings{ WOS:000382388400025, Author = {Ichimura, Takumi and Uemoto, Takuya}, Book-Group-Author = {IEEE}, Title = {Analysis of the Social Community Based on the Network Growing Model in Open Source Software Community}, Booktitle = {2015 IEEE 8TH INTERNATIONAL WORKSHOP ON COMPUTATIONAL INTELLIGENCE AND APPLICATIONS (IWCIA) PROCEEDINGS}, Year = {2015}, Pages = {149-153}, Note = {8th IEEE International Workshop on Computational Intelligence and Applications (IWCIA), Hiroshima, JAPAN, NOV 06-07, 2015}, Organization = {IEEE; IEEE Syst Man \& Cybernet Soc, Hiroshima Chapter}, Abstract = {The social community in open source software developers has a complex network structure.

Over half of them also are matched to projects of known membership sizes, revealing that although some members from each of the clusters are present in the small, medium and large ranges of the distribution of project sizes, the mixing fractions for the large and the very small project ranges are statistically different. Among developers who changed projects, there is a discernable flow from the bottom toward the very small towards to large projects. some of which is motivated by individuals seeking to improve their programming skills.

The absence of GPS in extraplanetary environments prevents surface vehicles from knowing their exact location, which raises the need for an alternative positioning system. Traditional methods, such as visual odometry cross-referenced with digital elevation maps, are limited by their dependence on human input and pre-existing space infrastructure. This paper outlines and characterizes a global position determination algorithm intended for planetary surface vehicles in GPS-denied environments without any prior knowledge. The localization algorithm receives images of the stars from a visible camera and tilt measurements from an inclinometer, derives star locations and a gravity vector, and combines these signals to generate an onboard position determinant. This paper contributes (i) the first open-source planetary global localization algorithm based on stars, (ii) a sensor suite design derived of solely commercial-off-the-shelf (COTS) components, and (iii) an unprecedented physical experiment and characterization from this algorithm on Earth's surface. The resulting position determinant is on average 100km from the testing location, consistent across various time and surface inclines. This result is compared to theoretical performance, state-of-the-art sensor performance, and other global localization methods. This achieved determinant error offers a starting point toward localization improvement with more capable sensors and the incorporation of multiple historical determinants for state estimation.}, DOI = {10.1109/iSpaRo60631.2024.10688190}, ISBN = {979-8-3503-6723-2}, ResearcherID-Numbers = {Wang, Hao/LSK-5016-2024 }, ORCID-Numbers = {Wang, Hao/0000-0002-6587-4126}, Unique-ID = {WOS:001327765400024}, } @article{ WOS:000212536800004, Author = {Ketterl, Markus and Schulte, Olaf A. and Hochman, Adam}, Title = {Opencast Matterhorn A community-driven open source software project for producing, managing, and distributing academic video}, Journal = {INTERACTIVE TECHNOLOGY AND SMART EDUCATION}, Year = {2010}, Volume = {7}, Number = {3, SI}, Pages = {168+}, Abstract = {Purpose - The purpose of this paper is to introduce the Opencast Community, a global community of individuals, institutions, and commercial stakeholders exchanging knowledge about all matters relevant in the context of academic video and promoting projects in this context.

RE is characterized as a socio-technical distributed cognitive (DCog) activity where multiple actors deploy artifacts to `compute' requirements. To uncover how OSS projects configure the socio-technical distribution of cognitive processes to respond to varying attributes of incoming requirements we conduct a comparative analysis of four successful OSS projects. We observe that the volume of requirements faced by an OSS group dictates largely the nature of its social formation while the volatility experienced in the requirements dictates the overlap the project exhibits with the larger external community.

This study examines the impacts of lockdown on innovation-driven work productivity, focusing on contributions to open source software (OSS) projects on GitHub, the world's largest OSS platform. By leveraging two lockdowns in China as natural experiments, we discover that developers in the 2021 Xi'an lockdown increased OSS contributions by 9.0 \%, while those in the 2020 Wuhan lockdown reduced their contributions by 10.5 \%. A subsequent survey study elucidates this divergence, uncovering an adaptation effect wherein Xi'an developers became more accustomed to the new norm of WFH over time, capitalizing on the flexibility and opportunities of remote work. Moreover, our findings across both lockdowns reveal that the lack of face-to-face (F2F) interactions significantly impeded OSS contributions, whereas the increased available time at home positively influenced them. This finding is especially noteworthy as it challenges the assumption that CMC can effortlessly substitute for F2F interactions without negatively affecting productivity. We further examine the impacts of stay-at-home orders in the United States (US) on OSS contributions and find no significant effects. Collectively, our research offers valuable insights into the multifaceted impacts of lockdown on productivity, shedding light on how individuals adapt to remote work norms during protracted disruptions like a pandemic.

Consequently, software engineers are adopting pre-trained models (PTMs) for their downstream applications. The dynamics of the PTM supply chain remain largely unexplored, signaling a clear need for structured datasets that document not only the metadata but also the subsequent applications of these models. Without such data, the MSR community cannot comprehensively understand the impact of PTM adoption and reuse. This paper presents the PeaTMOSS dataset, which comprises metadata for 281,638 PTMs and detailed snapshots for all PTMs with over 50 monthly downloads (14,296 PTMs), along with 28,575 open-source software repositories from GitHub that utilize these models. Additionally, the dataset includes 44,337 mappings from 15,129 downstream GitHub repositories to the 2,530 PTMs they use. To enhance the dataset's comprehensiveness, we developed prompts for a large language model to automatically extract model metadata, including the model's training datasets, parameters, and evaluation metrics. Our analysis of this dataset provides the first summary statistics for the PTM supply chain, showing the trend of PTM development and common shortcomings of PTM package documentation. Our example application reveals inconsistencies in software licenses across PTMs and their dependent projects.

The study is conducted on 13 open source systems comprising over 14 MLOC. Each for-loop is statically analyzed to determine if it can be parallelized or not. A for-loop that can be parallelized is termed a free-loop. Free-loops can be easily parallelized using tools such as OpenMP. For the loops that cannot be parallelized, the various inhibitors to parallelization are determined and tabulated. The data shows that the most prevalent inhibitor by far, is functions called within for-loops that have side effects. This single inhibitor poses the greatest challenge in adapting and re-engineering systems to better utilize modern multi-core architectures. This fact is somewhat contradictory to the literature, which is primarily focused on the removal of data dependencies within loops. Results of this paper also show that function calls via function pointers and virtual methods have very little impact on the for-loop parallelization process. Historical data over a 10-year period of inhibitor counts for the set of systems studied is also presented. It shows that there is little change in the potential for parallelization of loops over time.}, DOI = {10.1007/s10664-015-9385-5}, ISSN = {1382-3256}, EISSN = {1573-7616}, Unique-ID = {WOS:000379061700016}, } @inproceedings{ WOS:001290434602074, Author = {Zhuang, Yuqian and Zhang, Mingya and Yang, Yiyuan and Wang, Liang}, Editor = {Shen, W and Barthes, JP and Luo, J and Qiu, T and Zhou, X and Zhang, J and Zhu, H and Peng, K and Xu, T and Chen, N}, Title = {Analyzing Women's Contributions to Open-Source Software Projects based on Large Language Models}, Booktitle = {PROCEEDINGS OF THE 2024 27 TH INTERNATIONAL CONFERENCE ON COMPUTER SUPPORTED COOPERATIVE WORK IN DESIGN, CSCWD 2024}, Series = {International Conference on Computer Supported Cooperative Work in Design}, Year = {2024}, Pages = {2363-2368}, Note = {27th International Conference on Computer Supported Cooperative Work in Design (CSCWD), Tianjin, PEOPLES R CHINA, MAY 08-10, 2024}, Abstract = {Open-source software (OSS) enables users to access, modify, distribute software based on open-source licenses, serving as vital digital infrastructure.

Knowledge can be shared, and the knowledge sharing cycle has two processes: knowledge donation, when a person voluntarily offers his intellectual capital to others, and knowledge collection, when a person consults other people's intellectual capital. Knowledge sharing is important for, among other reasons, improving organizational learning, innovative capacity, organizational success and productivity. Knowledge can be shared among individuals, groups and organizations. One kind of group organized to share knowledge is the community of practice, where people have mutual relationships involving a regular flow of knowledge between them, which facilitates the generation of new knowledge. A free software community is a type of community of practice arranged around a specific free software. The knowledge shared in free software communities is complex and the knowledge sharing processes have scarcely been studied in this environment. This investigation aims to identify the profiles of knowledge sharing processes in free software communities i.e., whether members of free software communities collect more, donate more or collect and donate equally. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters, corresponding to the sharing profiles of the respondents, were identified: Sporadic Sharer (low donation and low collection); Collector (low donation and high collection); Donator (high donation and low collection); and Constant Sharer (high donation and high collection). The k-means algorithm showed four well-defined clusters. Interestingly, with the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators (that emphasize donation) and Collectors (that emphasize collection). These results confirm the view of free software communities as communities of practice that are organized to share knowledge, and highlight the importance of knowledge sharing and collaboration in the free software development cycle. Furthermore, the results show that the Constant Sharer (that both collects and donates intensely) is the profile that donates and collects more, even more than Donators and Collectors, indicating that this profile is key to the correct functioning of the community.}, ISSN = {2048-8963}, ISBN = {978-1-911218-03-6}, ResearcherID-Numbers = {Balle, Andrea/O-7855-2016 Oliveira, Mirian/IZQ-0495-2023 Oliveira, Mirian/B-5090-2010 }, ORCID-Numbers = {Oliveira, Mirian/0000-0002-5498-0329 Balle, Andrea/0000-0003-2521-5342}, Unique-ID = {WOS:000400276800005}, } @article{ WOS:000749605800006, Author = {Ye, Ye and Barapatre, Seemran and Davis, Michael K. and Elliston, Keith O. and Davatzikos, Christos and Fedorov, Andrey and Fillion-Robin, Jean-Christophe and Foster, Ian and Gilbertson, John R. and Lasso, Andras and Miller, V, James and Morgan, Martin and Pieper, Steve and Raumann, Brigitte E. and Sarachan, Brion D. and Savova, Guergana and Silverstein, Jonathan C. and Taylor, Donald P. and Zelnis, Joyce B. and Zhang, Guo-Qiang and Cuticchia, Jamie and Becich, Michael J.}, Title = {Open-source Software Sustainability Models: Initial White Paper From the Informatics Technology for Cancer Research Sustainability and Industry Partnership Working Group}, Journal = {JOURNAL OF MEDICAL INTERNET RESEARCH}, Year = {2021}, Volume = {23}, Number = {12}, Month = {DEC 2}, Abstract = {Background: The National Cancer Institute Informatics Technology for Cancer Research (ITCR) program provides a series of funding mechanisms to create an ecosystem of open-source software (OSS) that serves the needs of cancer research. As the ITCR ecosystem substantially grows, it faces the challenge of the long-term sustainability of the software being developed by ITCR grantees. To address this challenge, the ITCR sustainability and industry partnership working group (SIP-WG) was convened in 2019. Objective: The charter of the SIP-WG is to investigate options to enhance the long-term sustainability of the OSS being developed by ITCR, in part by developing a collection of business model archetypes that can serve as sustainability plans for ITCR OSS development initiatives. The working group assembled models from the ITCR program, from other studies, and from the engagement of its extensive network of relationships with other organizations (eg, Chan Zuckerberg Initiative, Open Source Initiative, and Software Sustainability Institute) in support of this objective. Methods: This paper reviews the existing sustainability models and describes 10 OSS use cases disseminated by the SIP-WG and others, including 3D Slicer, Bioconductor, Cytoscape, Globus, i2b2 (Informatics for Integrating Biology and the Bedside) and tranSMART, Insight Toolkit, Linux, Observational Health Data Sciences and Informatics tools, R, and REDCap (Research Electronic Data Capture), in 10 sustainability aspects: governance, documentation, code quality, support, ecosystem collaboration, security, legal, finance, marketing, and dependency hygiene. Results: Information available to the public reveals that all 10 OSS have effective governance, comprehensive documentation, high code quality, reliable dependency hygiene, strong user and developer support, and active marketing. These OSS include a variety of licensing models (eg, general public license version 2, general public license version 3, Berkeley Software Distribution, and Apache 3) and financial models (eg, federal research funding, industry and membership support, and commercial support). However, detailed information on ecosystem collaboration and security is not publicly provided by most OSS. Conclusions: We recommend 6 essential attributes for research software: alignment with unmet scientific needs, a dedicated development team, a vibrant user community, a feasible licensing model, a sustainable financial model, and effective product management. We also stress important actions to be considered in future ITCR activities that involve the discussion of the sustainability and licensing models for ITCR OSS, the establishment of a central library, the allocation of consulting resources to code quality control, ecosystem collaboration, security, and dependency hygiene.}, DOI = {10.2196/20028}, Article-Number = {e20028}, ISSN = {1438-8871}, ResearcherID-Numbers = {Foster, Ian/GNH-1877-2022 Ye, Ye/T-2154-2019 Fedorov, Andrey/I-7296-2019 Lasso, Andras/D-4914-2011 }, ORCID-Numbers = {Elliston, Keith/0000-0002-9110-9233 Lasso, Andras/0000-0002-4220-7064 Fedorov, Andrey/0000-0003-4806-9413 Ye, Ye/0000-0002-1138-9846 Davis, Michael/0000-0002-7754-3957 Fillion-Robin, Jean-Christophe/0000-0002-9688-8950}, Unique-ID = {WOS:000749605800006}, } @article{ WOS:000713412300003, Author = {Hildebrand, Jayne}, Title = {Environmental Desire in: The Mill on the Floss}, Journal = {NINETEENTH-CENTURY LITERATURE}, Year = {2021}, Volume = {76}, Number = {2}, Pages = {192-222}, Month = {SEP}, Abstract = {This essay argues that George Eliot's expansive use of landscape description in The Mill on the Floss (1860) represents an engagement with the emerging concept of a biological ``medium{''} or ``environment{''} in the nineteenth-century sciences. In the 1850s, scientific writers including Auguste Comte, Herbert Spencer, and G. H. Lewes redefined biological life as dependent on an abstraction called a ``medium{''} or ``environment{''}- a term that united all the objects, substances, and forces in an organism's physical surroundings into a singular entity. Eliot in The Mill on the Floss draws out the ecological potential of this new biological concept by imbuing the described backgrounds of her novel with a lyrical affect I call ``environmental desire,{''} a diffuse longing for ambient contact with one's formative medium that offers an ethical alternative to the possessive and object-driven forms of desire that drive the plot of a traditional Bildungsroman. Maggie Tulliver's marriage plot is structured by a tension between environmental desire and possessive desire, in which her erotic desire for Stephen Guest competes with a more diffuse environmental desire that attaches to the novel's described backgrounds. Ultimately, the new environment concept enables Eliot to reconceive the Bildungsroman's usual opposition between self and world as a relationship of nourishment and dependency rather than struggle, and invites a reconsideration of the ecological role of description in the Bildungsroman genre.}, DOI = {10.1525/ncl.2021.76.2.192}, ISSN = {0891-9356}, Unique-ID = {WOS:000713412300003}, } @article{ WOS:000811207100001, Author = {Kuang, Li and Zhou, Cong and Yang, Xiaoxian}, Title = {Code comment generation based on graph neural network enhanced transformer model for code understanding in open-source software ecosystems}, Journal = {AUTOMATED SOFTWARE ENGINEERING}, Year = {2022}, Volume = {29}, Number = {2}, Month = {NOV}, Abstract = {In open-source software ecosystems, the scale of source code is getting larger and larger, and developers often use various methods (good code comments or method names, etc.) to make the code easier to read and understand. However, high-quality code comments or method names are often unavailable due to tight project schedules or other reasons in open-source software ecosystems such as Github. Therefore, in this work, we try to use deep learning models to generate appropriate code comments or method names to help software development and maintenance, which requires a non-trivial understanding of the code. Therefore, we propose a Graph neural network enhanced Transformer model (GTrans for short) to learn code representation to understand code better. Specifically, GTrans learns code representation from code sequences and graphs. We use a Transformer encoder to capture the global representation from code sequence and a graph neural network (GNN) encoder to focus on the local details in the code graph, and then use a decoder to combine both global and local representations by attention mechanism. We use three public datasets collected from GitHub to evaluate our model. In an extensive evaluation, we show that GTrans outperforms the state-of-the-art models up to 3.8\% increase in METEOR metrics on code comment generation and outperforms the state-of-the-art models by margins of 5.8\%-9.4\% in ROUGE metrics on method name generation after some adjustments on the structure. Empirically, we find the method name generation task depends on more local information than global, and the code comment generation task is in contrast.

The convenient sampling technique was used to collect data. The data collected were interpreted using descriptive statistics and independent t-test. Findings - The results reveal that Chinese research and academics libraries depend mostly upon commercial software and place a great deal of trust on locally produced free software. This situation may be caused due to the lack of professional knowledge in OSS and lack of appropriate technical expertise. Although there were a sufficient number of librarians who have shown interest in OSS, they did not enthusiastically agree to implement it in their libraries. Furthermore, the interviews highlighted the professionals' opinion that most librarians are reluctant to adopt OSS due to the risk factor, lack of professional expertise, insufficient interest of the Chinese Government and lack of professional training.

Our work addresses this challenge and develops a simple approach to iteratively explore the attack surface of supply chain residual vulnerabilities in open source projects. We have assessed our search scheme on 50 GitHub-hosted projects having high stars and forks: we mine their bug fix commits and identify buggy package versions to track the affected dependents and estimate the potential attack surface. We find that many projects fix their vulnerable issues by update their dependency versions, and version inheritance is a significant cause of supply chain attacks for open source projects.}, DOI = {10.1109/QRS54544.2021.00060}, ISSN = {2693-9185}, EISSN = {2693-9177}, ISBN = {978-1-6654-5813-9}, ResearcherID-Numbers = {Yan, Dapeng/A-2677-2015 LIU, zhe/HGD-6875-2022 }, ORCID-Numbers = {LIU, Kui/0000-0003-0145-615X}, Unique-ID = {WOS:000814747000050}, } @article{ WOS:000600676600043, Author = {Ladroit, Yoann and Escobar-Flores, Pablo C. and Schimel, Alexandre Cg and O'Driscoll, Richard L.}, Title = {ESP3: An open-source software for the quantitative processing of hydro-acoustic data}, Journal = {SOFTWAREX}, Year = {2020}, Volume = {12}, Month = {JUL-DEC}, Abstract = {ESP3 is an open-source software to process single-beam and split-beam echosounder data.

This feedback is generally reported in the form of new issues for the project, managed by the so-called issue-trackers. One of the features provided by most issue-trackers is the possibility to define a set of labels/tags to classify the issues and, at least in theory, facilitate their management. Nevertheless, there is little empirical evidence to confirm that taking the time to categorize new issues has indeed a beneficial impact on the project evolution. In this paper we analyze a population of more than three million of GitHub projects and give some insights on how labels are used in them. Our preliminary results reveal that, even if the label mechanism is scarcely used, using labels favors the resolution of issues. Our analysis also suggests that not all projects use labels in the same way (e.g., for some labels are only a way to prioritize the project while others use them to signal their temporal evolution as they move along in the development workflow). Further research is needed to precisely characterize these label ``families{''} and learn more the ideal application scenarios for each of them.}, ISBN = {978-1-4799-8469-5}, ResearcherID-Numbers = {Cabot, Jordi/P-7723-2015 Canovas Izquierdo, Javier Luis/E-8940-2016}, ORCID-Numbers = {Cabot, Jordi/0000-0003-2418-2489 Canovas Izquierdo, Javier Luis/0000-0002-2326-1700}, Unique-ID = {WOS:000380389500066}, } @article{ WOS:000309043100005, Author = {Phannachitta, Passakorn and Ihara, Akinori and Jirapiwong, Pijak and Ohira, Masao and Matsumoto, Ken-ichi}, Title = {An Algorithm for Gradual Patch Acceptance Detection in Open Source Software Repository Mining}, Journal = {IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCES}, Year = {2012}, Volume = {E95A}, Number = {9}, Pages = {1478-1489}, Month = {SEP}, Abstract = {Nowadays, software development societies have given more precedence to Open Source Software (OSS).

However, micro-CT does not allow the assessment of bone turnover parameters such as bone formation rate and osteoclast (OC) number and surface.

The main purpose of this study was to develop and validate a relatively easy and rapid method to measure static and dynamic bone histomorphometry parameters. Here we present the adaptation of established staining protocols and three novel open source image analysis packages: TrapHisto, OsteoidHisto and CalceinHisto that allow rapid, semi-automated analysis of histomorphometric bone resorption, osteoid, and calcein double labelling parameters respectively. These three programs are based on ImageJ, but use a relatively simple user interface that hides the underlying complexity of the image analysis. (c) 2017 The Authors.

In SRGM, the degree of reliability growth may fluctuate greatly according to change in the internal state of the software. It is called the change point (CP). Several researchers proposed the SRGM considering CP. In the open source software (OSS), there are many projects that continue development even after the software is released. Therefore, major updates with breaking changes may occur in it. The major updates can be a factor that causes a CP because it greatly changes the internal state of the OSS. This paper focuses on the relationship between CP and software updates. We collect OSS fault data from a bug tracking system. Moreover, we examine the behavior of SRGM before and after software updates. Furthermore, we discuss the applicability of SRGM for CP in OSS. Also, we compare the proposed model based on CP with the model without CP. As a result, we have confirmed that the SRGM can evaluate the reliability in the environment with major updates. Moreover, the proposed method performs better than without considering CP model. Especially, the exponential model's mean value function is the suitable method to assess the OSS reliability for the proposed method.}, DOI = {10.1142/S0218539324500049}, EarlyAccessDate = {APR 2024}, ISSN = {0218-5393}, EISSN = {1793-6446}, Unique-ID = {WOS:001210020100001}, } @inproceedings{ WOS:000723649200002, Author = {Niemirepo, Teo T. and Viitanen, Marko and Vanne, Jarno}, Book-Group-Author = {ASSOC COMP MACHINERY}, Title = {Open3DGen: Open-Source Software for Reconstructing Textured 3D Models from RGB-D Images}, Booktitle = {MMSYS `21: PROCEEDINGS OF THE 2021 MULTIMEDIA SYSTEMS CONFERENCE}, Year = {2021}, Pages = {12-22}, Note = {12th ACM Multimedia Systems Conference (MMSys), Istanbul, TURKEY, SEP 28-OCT 01, 2021}, Organization = {ACMSIGMM; Assoc Comp Machinery; ACMSIGCOMM; ACM SIGMOBILE}, Abstract = {This paper presents the first entirely open-source and cross-platform software called Open3DGen for reconstructing photorealistic textured 3D models from RGB-D images.

Using a conventional protocol to fabricate IHS from casts of the initial situation or the wax-up can be challenging, time-consuming, and sometimes frustrating. A digital workflow makes this process quicker and more convenient. The IHS must be first designed with computer-aided design (CAD), then fabricated with computer-aided manufacture (CAM). Proprietary dental software is commonly used for the design process but needs to be purchased. Objective: To describe a step-by-step technique for designing an IHS for posterior relining with open-source software. Methods: This paper describes a straightforward procedure to design an IHS from a dental scan of the initial situation or a digital wax-up for an esthetic and functional temporary rehabilitation. Results: An IHS can be quickly designed using open-source software by copying an existing restoration or a conventional or digital wax-up. Then, the design can be 3D printed using a biocompatible resin. Conclusions: The clinician can use open-source software to design IHSs, which are then 3D printed using a biocompatible resin. Clinical relevance: The clinician can design IHSs from a dental scan of the initial situation or a wax-up using opensource software by following the step-by-step protocol outlined in this paper.

In this paper, we develop a tool, SoftMon, that can compare the codebases of two separate applications and pinpoint the exact set of functions that are disproportionately responsible for differences in performance. Our tool uses machine learning and NLP techniques to analyze why a given open-source application has a lower performance as compared to its peers, design bespoke applications that can incorporate specific innovations (identified by SoftMon) in competing applications, and diagnose performance bugs. In this paper, we compare a wide variety of large open-source programs such as image editors, audio players, text editors, PDF readers, mail clients and even full-fledged operating systems (OSs). In all cases, our tool was able to pinpoint a set of at the most 10-15 functions that are responsible for the differences within 200 seconds.

This model is a liquid-solid mixture model inspired from the pioneer work of Bennon and Incropera, including mass, momentum, energy and species conservation equations. In particular, the energy conservation equation is formulated with the temperature variable, the thermosolutal convection is accounted for through the Boussinesq approximation and the interdendritic flow in the mushy zone is governed by the Darcy's law. Furthermore, a rigid solid phase is assumed and classical microsegregation models are used featuring lever-rule or Gulliver-Scheil assumptions. At the discrete level, a first-order upwind scheme is implemented with a SIMPLEC approach to solve the velocity-pressure coupling. The other couplings involving temperature and concentration fields are efficiently solved performing sub-loops with a PISO-like approach. The overall scheme is mainly implicit with additional treatments to ensure the equilibrium between the hydrostatic pressure gradient and the buoyant forces, and to deal properly with solid zones. The segregation predictions offered by the model are validated against both academic test case and industrial ingot configurations. A convergence study is also led focusing on time step and mesh size sensitivities.}, DOI = {10.1088/1757-899X/861/1/012033}, Article-Number = {012033}, ISSN = {1757-8981}, Unique-ID = {WOS:000594112500033}, } @article{ WOS:000479057800009, Author = {Slyadnev, S.

Another example is the interactive reconstruction of the turbine blade from an unstructured surface triangulation. In both the cases, we use a surface skinning strategy enhanced by a curve fairing operator. We show that the modified skinning operator does not minimize the total bending energy of the surface, but yields a smooth patch where input inaccuracies are compensated for. The reconstruction result is a parametric model of the turbine blade where the design variables are the coordinates of the poles for each profile curve.

A hidden Markov model (HMM) is proposed that allows us to investigate (1) the extent to which individuals learn from their own experience and from interactions with peers, (2) whether an individual's ability to learn from these activities varies as she evolves/learns over time, and (3) to what extent individual learning persists over time. We calibrate the model based on six years of detailed data collected from 251 developers working on 25 OSS projects hosted at Sourceforge. Using the HMM, three latent learning states (high, medium, and low) are identified, and the marginal impact of learning activities on moving the developer between these states is estimated. Our findings reveal different patterns of learning in different learning states. Learning from peers appears to be the most important source of learning for developers across the three states. Developers in the medium learning state benefit the most through discussions that they initiate. On the other hand, developers in the low and the high states benefit the most by participating in discussions started by others. While in the low state, developers depend entirely upon their peers to learn, whereas in the medium or high state, they can also draw upon their own experiences. Explanations for these varying impacts of learning activities on the transitions of developers between the three learning states are provided.

The techniques for performing inspections have been well studied in industry; in OSS development, peer reviews are less well understood. We examine the two peer review techniques used by the successful, mature Apache server project: review-then-commit and commit-then-review. Using archival records of email discussion and version control repositories, we construct a series of metrics that produces measures similar to those used in traditional inspection experiments. Specifically, we measure the frequency of review, the level of participation in reviews, the size of the artifact under review, the calendar time to perform a review, and the number of reviews that find defects. We provide a comparison of the two Apache review techniques as well as a comparison of Apache review to inspection in an industrial project. We conclude that Apache reviews can be described as (1) early, frequent reviews (2) of small, independent, complete contributions (3) conducted asynchronously by a potentially large, but actually small, group of self-selected experts (4) leading to an efficient and effective peer review technique.}, ISBN = {978-1-60558-079-1}, Unique-ID = {WOS:000266158500055}, } @inproceedings{ WOS:000254288200021, Author = {Tamura, Yoshinobu and Yamada, Shigeru}, Book-Group-Author = {IEEE}, Title = {Software reliability growth model based on stochastic differential equations for open source software}, Booktitle = {2007 IEEE INTERNATIONAL CONFERENCE ON MECHATRONICS}, Year = {2007}, Pages = {107+}, Note = {IEEE International Conference on Mechatronics, Kumamoto, JAPAN, MAY 08-10, 2007}, Organization = {IEEE}, Abstract = {All over the world people can gain the information at the same time by growing rate of Internet access around the world in recent years.

Using information contained in the bug reports and source code, we classify faults based on how they depend on the operating environment. We find that 72-87\% of the faults are independent of the operating environment and are hence deterministic (non-transient). Recovering from the failures caused by these faults requires the use Of application-specific knowledge. Half of the remaining faults depend on a condition in the operating environment that is likely to persist on retry, and the failures caused by these faults are also likely to require application-specific recovery. Unfortunately, only 5-14\% of the faults were triggered by transient conditions, such as timing and synchronization, that naturally fix themselves during recovery.

Direct measurements of turbulent fluxes are very challenging and sparse, and do not span the full range of environmental conditions that exist over the ocean. This means that empirical ``bulk formulae{''} parameterizations that relate direct flux observations to concurrent measurements of the mean meteorological and sea surface variables contain considerable uncertainty. In this paper, we present a Python 3.6 (or higher) open-source software package ``AirSeaFluxCode{''} for the computation of the heat (latent and sensible) and momentum fluxes. Ten different parameterizations are included, each based on published descriptions or code and each derived from a different set of observations, or different assumptions about the turbulent exchange processes. They represent a range of current expert opinion on how the fluxes depend on mean properties and can be used to explore uncertainty in calculated fluxes. AirSeaFluxCode also allows the adjustment of the mean meteorological input parameters (air temperature, humidity and wind speed) from the height at which they are obtained to a user-defined output height. This height adjustment enables the comparison of measurements, or model-derived values, made at different heights above sea-level. The parameterizations calculate the fluxes using input parameters that are relatively easily to measure, or are available as model output: wind speed, air temperature, sea surface temperature, atmospheric pressure and humidity. Where original code is available we have compared its output with that of AirSeaFluxCode. Any changes made to increase consistency across algorithms by standardizing computational methods or calculation of meteorological variables, for example, are discussed and the impacts quantified: these are shown to be insignificant except for a few cases where conditions were extreme, and AirSeaFluxCode is shown to be robust. We also investigate the impact on the fluxes caused by different assumptions about the exchange processes, or the choices inherent in the implementation of the parameterizations. For example, sea surface temperature usually refers to data typically obtained at depths of between 1 and 10 m. However, since some parameterizations require a ``skin{''} sea surface temperature, code that adjusts temperature at depth to skin temperature is included: this has a very significant impact on the fluxes. Selecting a parameterization that is appropriate for the available sea surface temperature will avoid the need to adjust the sea temperature data and the uncertainties associated with that adjustment, and will also avoid the biases due to use of the ``wrong{''} measure of temperature. Significant differences also resulted from assumptions about the size of reduction in sea surface humidity to account for salinity effects: the uncertainty in the reduction factor needs to be quantified in future analyses. Fluxes in extreme conditions are particularly uncertain since the transfer coefficients in the different parameterizations vary most at very high and very low wind speeds. Low wind speeds are also challenging for numerical implementation since choices have to be made regarding: convergence criteria for the iterative calculation, inclusion of a parameterization for convective gustiness, or application of ad hoc limits to various parameters. All of these choices can significantly affect the flux estimates for light winds.}, DOI = {10.3389/fmars.2022.1049168}, Article-Number = {1049168}, EISSN = {2296-7745}, ResearcherID-Numbers = {Cornes, Richard/B-5456-2010 yelland, m/E-6343-2011 Kent, Elizabeth/C-1281-2011 Berry, David/C-1268-2011}, ORCID-Numbers = {Kent, Elizabeth/0000-0002-6209-4247 Biri, Stavroula/0000-0002-5402-1072 Berry, David/0000-0002-3862-3479}, Unique-ID = {WOS:000937735600001}, } @incollection{ WOS:000442905400030, Author = {Ghafele, Roya and Gibert, Benjamin}, Book-Group-Author = {Informat Resources Management Assoc}, Title = {Open Growth: The Impact of Open Source Software on Employment in the USA}, Booktitle = {OPEN SOURCE TECHNOLOGY: CONCEPTS, METHODOLOGIES, TOOLS, AND APPLICATIONS}, Year = {2015}, Pages = {528-560}, Abstract = {Open Source Software (OSS) is well established in sectors as diverse as aviation, health, telecommunications, finance, publishing, education, and government.

OSS is thus believed to be a strong contributor to growth in high-value employment in the US.

In the case of FOSS (Free and Open Source Software) systems, many upgrade errors cannot be discovered by current upgrade managers and then a system upgrade can potentially lead the system to an inconsistent and incoherent state. Objective: The objective of this paper is to propose an approach to simulate the upgrade of complex systems in order to predict errors before they affect the real system. Method: The approach promotes the use of model-driven engineering techniques to simulate the upgrade of complex systems. The basic idea is to have a model-based description of the system to be upgraded and to make use of model transformations to perform the upgrade on a source model so to obtain a target model representing the state of the upgraded system. Results: We provide an implementation of the simulator, which is tailored to FOSS systems. The architecture of the simulator is distribution independent so that it can be easily instantiated to specific distributions. The simulator takes into account also pre and post-installation scripts that equip each distribution package. This feature is extremely important since maintainer scripts are full-fledged programs that are run with system administration rights. Conclusions: The paper shows the kind of errors the simulator is able to predict before upgrading the real system, and how the approach improves the state of the art of package managers while integrated in real Linux distribution installations.

This first version is characterized by its flexibility and non-commerciality, and it is available without any conditions on the following website: https://www.github.com/LAHCEN-EL-AMRI/Gamma-Spectra-Analysis, allowing users to add personal options, making it a particularly adaptable tool to the different requirements of scientific research. This article deals with the second version of GSA, which focuses on a core and complementary feature: the calculation of isotope activity. In order to accomplish this goal, instead of implementing a single efficiency formula, as is often the case in most software, four formulas were integrated. The users can therefore select the one they want to implement. To ensure the accuracy and reliability of this new feature, a validation was performed on GSA. The results obtained with GSA v2 were carefully studied by comparing them to those obtained with the renowned Genie 2000 software. Owing to this comparison step, it was possible to verify and confirm the accuracy of the results of GSA version 2.

Currently coupled computations solve the same governing equations using different coupling methods, which can be sorted into two categories: loose coupling and tight coupling. This paper proposes and verifies a third coupling approach called ``the Integrated Tight Coupling (ITC) method{''}. The mathematical equations in the nuclear fuel are rearranged to be integrated via a novel concept of the energy-group function. In addition, the data from the neutron cross section library can be used directly. The ITC method is implemented using two open-source codes: the DRAGON code and OpenFOAM. Additionally, a coupled computation using these two codes is new and has not been done. The ITC method is verified using a 1.5-D (1-D neutronics and 2-D thermal-hydraulics) symmetric unit cell example. The mesh of the tightly integrated computation is 25\% coarser than the loosely coupled one. Starting from a similar initial guess, the number of iterations for the ITC method is 24\% fewer than that for the loosely coupled computation to reach the same accuracy. In addition, the ITC method is tested with different initial guesses. For all cases tested, the scheme converged to the same solution. With further improvement and additional testing, the ITC method has the potential to be incorporated with other neutronics and thermal-hydraulics codes. (C) 2015 Elsevier Ltd.

An abundant amount of effort has been put by the research community to develop software maintainability prediction (SMP) models by relating software metrics to the maintainability of modules or classes. When software classes demanding the high maintainability effort (HME) are less as compared to the low maintainability effort (LME) classes, the situation leads to imbalanced datasets for training the SMP models. The imbalanced class distribution in SMP datasets could be a dilemma for various ML techniques because, in the case of an imbalanced dataset, minority class instances are either misclassified by the ML techniques or get discarded as noise. The recent development in predictive modeling has ascertained that ensemble techniques can boost the performance of ML techniques by collating their predictions. Ensembles themselves do not solve the class-imbalance problem much. However, aggregation of ensemble techniques with the certain techniques to handle class-imbalance problem (e.g., data resampling) has led to several proposals in research. This paper evaluates the performance of ensembles for the class-imbalance in the domain of SMP. The ensembles for class-imbalance problem (ECIP) are the modification of ensembles which pre-process the imbalanced data using data resampling before the learning process. This study experimentally compares the performance of several ECIP using performance metrics Balance and g-Mean over eight Apache software datasets. The results of the study advocate that for imbalanced datasets, ECIP improves the performance of SMP models as compared to classic ensembles.}, DOI = {10.1142/S0218539320400112}, Article-Number = {2040011}, ISSN = {0218-5393}, EISSN = {1793-6446}, ResearcherID-Numbers = {lata, kusum/JQX-1718-2023 Malhotra, Ruchika/ABC-3126-2020}, Unique-ID = {WOS:000562956000004}, } @inproceedings{ WOS:000521108600286, Author = {Argese, F. and Erriquez, G. and Galeandro, A. and Giraldo, M.

Business process management is intended to implement efficient and customer orientated processes whereby the simulation of business processes can be used to evaluate the quality of processes and to identify areas of improvements. Since real business processes usually contain decision processes which can be solved by optimization systems, it makes sense to,combine the simulation and the optimization of business processes. (Marz et.al. 2010, p 3ff.) As an example of a reasonable combined simulation and optimization of business processes, the navigation in a road network is discussed in this paper. Consider vehicles seeking the fastest route from a starting node to a target node using a navigation system. The amount of time spent driving on an arc is influenced by the distance and the amount of the vehicles on this arc and is continuously changing. The structure of the road network and the traffic within the network is described in a simulation model while the fastest path decisions of each vehicle are made by using an optimization system. There is obviously a relationship between the individual decisions made for each of the vehicles and the state of the entire network. The aim of this paper is to describe how a combined simulation and optimization of business processes can be created through using EPC-Simulator (Muller 2012) as a simulation system and CMPL (Steglich and Schleiff 2010) as an optimization system where the network traffic simulation is used exemplarily.}, DOI = {10.7148/2013-0808}, ISBN = {978-0-9564944-6-7}, Unique-ID = {WOS:000337114500122}, } @inproceedings{ WOS:000426954604045, Author = {Fabra, Fran and Cardellach, Estel and Li, Weiqiang and Rius, Antonio}, Book-Group-Author = {IEEE}, Title = {WAVPY: A GNSS-R OPEN SOURCE SOFTWARE LIBRARY FOR DATA ANALYSIS AND SIMULATION}, Booktitle = {2017 IEEE INTERNATIONAL GEOSCIENCE AND REMOTE SENSING SYMPOSIUM (IGARSS)}, Series = {IEEE International Symposium on Geoscience and Remote Sensing IGARSS}, Year = {2017}, Pages = {4125-4128}, Note = {IEEE International Geoscience \& Remote Sensing Symposium, Fort Worth, TX, JUL 23-28, 2017}, Organization = {Institute of Elect \& Electron Engineers Geoscience \& Remote Sensing Soc; IEEE; IEEE GRSS}, Abstract = {Due to the launch of a number of dedicated GNSS-R satellite missions during the last years, there is a potential raise of research interest in this field.

While already being used for clinical application, the complex interplay between these parameters requires thorough validation via simulations. These simulations required a realistic, controlled and adaptable model of the white matter axons with the surrounding myelin sheath. While there already exist useful algorithms to perform this task, none of them combine optimisation of axon packing, presence of myelin sheath and availability as free and open source software. Here, we introduce a novel disk packing algorithm that addresses these issues. The performance of the algorithm is tested in term of reproducibility over 50 runs, resulting density, and stability over iterations. This tool was then used to derive multiple values of FVF and to study the impact of this parameter on fr and MVF in light of the known microstructure based on histology sample. The standard deviation of the axon density over runs was lower than 10(-3) and the expected hexagonal packing for monodisperse disks was obtained with a density close to the optimal density (obtained: 0.892, theoretical: 0.907). Using an FVF ranging within {[}0.58, 0.82] and a mean inter-axon gap ranging within {[}0.1, 1.1] mu m, MVF ranged within {[}0.32, 0.44] and fr ranged within {[}0.39, 0.71], which is consistent with the histology.

It has been suggested that such small-scale and home-grown solutions (e.g. mobile phone apps), usually championed by social enterprises (SEs), are more likely to introduce pro-poor change than infrastructure heavy ICT initiatives designed by state and other international actors. In the Indian context, FOSS-based social innovations (SIs) introduced by SEs are helping poor communities tackle previously thought-to-be unresolvable socio-economic problems. An interesting question, therefore, would be: in what ways is the SE model and approach uniquely equipped to develop FOSS-based SIs that deliver pro-poor change? The empirical component of the research attempts to shed light on this question by uncovering the nuts and bolts of the development methodology deployed by an SE during the coding and launch of an FOSS-based SI. Findings highlight the significant role of the founder's social vision; the challenges of accurately capturing and translating to software developers the nature and nuance of social problems; and, the incumbent issues in putting together a methodology that creates active user engagement throughout the software development process, overcoming difficult barriers such as language and culture.

The controller plays the role of the `brain' that dictates the intelligent part of SDN technology. Various versions of SDN controllers exist as a response to the diverse demands and functions expected of them. There are several SDN controllers available in the open market besides a large number of commercial controllers; some are developed to meet carrier-grade service levels and one of the recent trends in open-source SDN controllers is the Open Network Operating System (ONOS). This paper presents a comparative study between open source SDN controllers, which are known as Network Controller Platform (NOX), Python-based Network Controller (POX), component-based SDN framework (Ryu), Java-based OpenFlow controller (Floodlight), OpenDayLight (ODL) and ONOS. The discussion is further extended into ONOS architecture, as well as, the evolution of ONOS controllers. This article will review use cases based on ONOS controllers in several application deployments. Moreover, the opportunities and challenges of open source SDN controllers will be discussed, exploring carrier- grade ONOS for future real-world deployments, ONOS unique features and identifying the suitable choice of SDN controller for service providers. In addition, we attempt to provide answers to several critical questions relating to the implications of the open-source nature of SDN controllers regarding vendor lock-in, interoperability, and standards compliance, Similarly, real-world use cases of organizations using open-source SDN are highlighted and how the open-source community contributes to the development of SDN controllers. Furthermore, challenges faced by open-source projects, and considerations when choosing an open-source SDN controller are underscored. Then the role of Artificial Intelligence (AI) and Machine Learning (ML) in the evolution of open-source SDN controllers in light of recent research is indicated. In addition, the challenges and limitations associated with deploying open-source SDN controllers in production networks, how can they be mitigated, and finally how open- source SDN controllers handle network security and ensure that network configurations and policies are robust and resilient are presented. Potential opportunities and challenges for future Open SDN deployment are outlined to conclude the article.}, DOI = {10.32604/cmc.2024.047009}, ISSN = {1546-2218}, EISSN = {1546-2226}, ResearcherID-Numbers = {Nordin, Rosdiadee/D-3482-2011 Amodu, Oluwatosin Ahmed/JFJ-2054-2023}, Unique-ID = {WOS:001290256900034}, } @inproceedings{ WOS:000366264105054, Author = {Steinmacher, Igor and Conte, Tayana Uchoa and Gerosa, Marco Aurelio}, Editor = {Bui, TX and Sprague, RH}, Title = {Understanding and Supporting the Choice of an Appropriate Task to Start With In Open Source Software Communities}, Booktitle = {2015 48TH HAWAII INTERNATIONAL CONFERENCE ON SYSTEM SCIENCES (HICSS)}, Series = {Proceedings of the Annual Hawaii International Conference on System Sciences}, Year = {2015}, Pages = {5299-5308}, Note = {48th Annual Hawaii International Conference on System Sciences (HICSS), Kauai, HI, JAN 05-08, 2015}, Organization = {IEEE Comp Soc; Univ Hawaii, Shidler Coll Business; Univ Hawaii, Dept EE; Univ Hawaii, Informat Sci Program; ONR; AFOSR; Natl Sci Fdn; IEEE Syst Sci \& Cybernet Soc; ACM; SIAM; IEEE Hawaii Sect; IEEE Control Syst Soc; IEEE Grp Informat Theory; IEEE Grp Automat Control; ARO; Reg Med Program Hawaii; Univ Hawaii, Coll Business Adm; Nasdaq}, Abstract = {Open Source Software (OSS) projects leverage the contribution of outsiders.

For laboratory lectures, we need a tool that is complete and easy to use. In this work we present a Java library which is oriented to teaching. This means that we have designed and built the library thinking in readability and understanding instead of efficiency. In this paper we present the open source project JavaVis, oriented to Computer Vision teaching. It consists of a framework with several features that make it useful for that purpose. It was designed to be easy to use: the user does not have to deal with internal structures and graphical interface, and adding a new algorithm is a simple task. We have developed three different modules, based on three different needs we have noticed in our subjects. The first one is a basic library for image processing. Besides the previously commented features, it supports geometrical data (edges, segments, points, etc.). The second module is based on the same working schema as the first one, but applied to 3D data. These two modules are enough for testing many well-known algorithms. They also suit the programming needs of students and teachers, as they can easily develop their own algorithms for the JavaVis framework. All JavaVis functions can be launched both from command line, as well as with the JavaVis Graphical User Interface. Finally we have extended JavaVis with a third module consisting of a visual desktop where different Computer Vision functions can be easily placed and connected. Its purpose is to visualize intermediate results in processes involving several functions, helping their better understanding. Once the library is presented, we focus on the experience using this library in several computer science courses. Our main goal using this library is that the students understand what they are doing. We have taken questionnaires during two years in order to know the improvement the students have gotten using the library.

The governing equations underlying MASCARET are the shallow water equations for unsteady flow propagation and the advection-dispersion equation for water quality and contaminant transport. The hydraulic component accounts for floodplains and storage areas, and flow at channel junction can be treated using a 2-D approach. Additionally, flood propagation over dry beds (e. g. dam-break flows) and non-hydrostatic waves can be simulated. The user interface FUDAA-MASCARET manages the input data, allocation of parameters, running of simulations and viewing outputs. MASCARET can be easily compiled as a dynamic library, offering special interfaces to be used with three main steps: Initialization, Run and Finalization of the calculation. With these features, MASCARET can be coupled or integrated to other softwares without requiring significant efforts. Since July 2011, MASCARET is worldwide distributed as an open-source code. In this paper, are presented various applications of this tool covering both flow hydrodynamic and water quality.

Our intuition is that participation offers tangible and intangible benefits to corporate participants. We show this by exploring a variety of models in game theory and use game theory as a methodological lens to explain the rationality of corporate participation in open source software development. Since game theory has evolved to include rational- and emotional-based reasons, we explore such lenses as cooperative games, metagames, coopetition, and Drama Theory. Our research question, Why do for-profit corporations participate in the development of open source software? was broad enough to adopt several useful perspectives to understand our data. One useful lens was game theory.

Results: We identified a continuum between core developers and OTCs. OTCs create smaller patches, face longer time intervals between patch submission and rejection, have longer review conversations, and face lower patch acceptance rates. Conversely, core contributors create larger patches, face shorter time intervals for feedback, have shorter review conversations, and have patches accepted at the highest rate.

In this paper, we empirically investigate the dependency concentration in smaller modules from a longitudinal perspective: (1) whether this concentration inequality always exists over product life time; (2) how it changes. We hypothesize that the concentration inequality should either remain at same levels or increase over time. This is because large-scale and long-lived software products usually go through some degree of continuous and intermittent refactoring. Our results show that dependencies concentrate in smaller classes in all releases, and this concentration inequality generally increases over successive releases. We suggest that software practitioners continuously pay a higher QA attention to smaller modules. We also recommend increasing such QA focus as a product matures and goes through refactoring activities.}, ISSN = {1063-6773}, ISBN = {978-1-4244-8629-8}, ResearcherID-Numbers = {Koru, Gunes/AAR-5819-2020}, Unique-ID = {WOS:000287356400022}, } @article{ WOS:000420021500004, Author = {Gastrow, M.}, Title = {OPEN INNOVATION IN SOUTH AFRICA: CASE STUDIES IN NANOTECHNOLOGY, BIOTECHNOLOGY, AND OPEN SOURCE SOFTWARE DEVELOPMENT}, Journal = {JOURNAL FOR NEW GENERATION SCIENCES}, Year = {2011}, Volume = {9}, Number = {1}, Pages = {42-66}, Month = {JAN}, Abstract = {In the era of open innovation, the capability to conduct collaborative research and development has become a key indicator of absorptive capacity and innovation competitiveness.

Nevertheless, much of the academic research on OSS has focused on individual rather than organizational issues. Hence while there is some understanding of why individual developers and users opt for particular OSS applications, relatively little is known about the adoption of OSS as a software acquisition policy. This paper presents a study of 13 managers in the secondary software sector in Europe, and examines how their perceptions of the benefits and drawbacks of OSS affected their decision to adopt an open source policy for software in their companies. The study reveals how their perceptions of the business and technical benefits and drawbacks of OSS influenced the technological, organizational, environmental and individual factors considered within the adoption process. The findings reveal that many of these factors are similar to those reported by previous work on the adoption of innovation, leading us to conclude that organizational processes for the adoption of open innovation are reliant on the practices for closed innovation despite frequently cited loss of organizational control associated with open innovation.}, ISSN = {0095-0033}, Unique-ID = {WOS:000278396200004}, } @article{ WOS:000266947500003, Author = {Ke, Weiling and Zhang, Ping}, Title = {Motivations in Open Source Software Communities: The Mediating Role of Effort Intensity and Goal Commitment}, Journal = {INTERNATIONAL JOURNAL OF ELECTRONIC COMMERCE}, Year = {2009}, Volume = {13}, Number = {4}, Pages = {39-66}, Month = {SUM}, Abstract = {As a community-based innovation, the open source software (OSS) development phenomenon has received great attention from researchers and practitioners.

When the measurement data is assumed to be obtained on a uniform grid which is staggered with respect to the discretization of the parameter volume, the resulting kernel sensitivity matrices exhibit block-Toeplitz-Toeplitzblock (BTTB) structure. These matrices are symmetric for the gravity problem but unsymmetric for the magnetic problem. In each case, the structure facilitates fast forward computation using two-dimensional fast Fourier transforms. The construction of the kernel matrices and the application of the transform for fast forward multiplication, for each problem, is carefully described. But, for purposes of comparison with the non-transform approach, the generation of the unique entries that define a given kernel matrix is also explained. It is also demonstrated how the matrices, and hence transforms, are adjusted when padding around the volume domain is introduced. The transform algorithms for fast forward matrix multiplication with the sensitivity matrix and its transpose, without the direct construction of the relevant matrices, are presented. Numerical experiments demonstrate the significant reduction in computation time and memory requirements that are achieved using the transform implementation. Thus, it becomes feasible, both in terms of reduced memory requirements and computational time, to implement the transform algorithms for large three-dimensional volumes. All presented algorithms, including with variable padding, are coded for optimal memory, storage and computation as an open source MATLAB code which can be adapted for any convolution kernel which generates a BTTB matrix, whether or not it is symmetric. This work, therefore, provides a general tool for the efficient simulation of gravity and magnetic field data, as well as any formulation which admits a sensitivity matrix with the required structure.}, DOI = {10.1016/j.cageo.2020.104575}, Article-Number = {104575}, ISSN = {0098-3004}, EISSN = {1873-7803}, ORCID-Numbers = {Renaut, Rosemary/0000-0001-9296-0890}, Unique-ID = {WOS:000580574900010}, } @inproceedings{ WOS:000683381700033, Author = {Aranha, Renan Vinicius and Casaes, Andre Biondi and Nunes, Fatima L.

The scientific literature presents several techniques that can be used to recognize the user's emotional state. However, many techniques involve the use of sensors that can result in financial costs and cause discomfort to the user. In this scenario, the recognition of the emotional state through the analysis of facial expressions presents itself as a useful and practical approach, since it does not involve the use of sensors attached to the user's body and executed in different types of devices. Despite these advantages, software that allow the analysis of facial expressions for free are still incipient, and performance evaluation of this type of software usually is not available.

The objective of this study was to develop a greenhouse environment measurement system using a low-cost microcontroller with open-source software. Greenhouse environment parameters measured were air temperature, relative humidity, and carbon dioxide (CO2) concentration. The ranges of the temperature, relative humidity, and CO2 concentration were -40 to 120 degrees C, 0 to 100\%, and 0 to 10,000 ppm, respectively. A 128 x 64 graphic LCD display was used for real-time monitoring of the greenhouse environments. An Arduino Uno R3 consisted of a USB interface for communicating with a computer, 6 analog inputs, and 14 digital input/output pins. A temperature/relative humidity sensor was connected to digital pins 2 and 3. A CO2 sensor was connected to digital pins 12 and 13. The LCD was connected to digital pin 1 (TX). The sketches were programmed with the Arduino Software (IDE). A measurement system including the Arduino board, sensors, and accessories was developed (totaling \$244). Data for the environmental parameters in a venlo-type greenhouse were obtained using this system without any problems.

Free open source software projects generally have one mailing list for developers and another one for users. This large number of mailing lists changes constantly and shows a great variety with respect to membership and topics covered. This makes them very difficult to monitor. One way of overcoming this Big Data Challenge is to identify some easily computable global indicators that can be used for instance to detect important events. We illustrate this approach here by making a social network analysis and comparison of developers' and users' mailing lists of four free open source software projects: CentOS, GnuPG, Mailman and Samba. We show that these mailing lists have some common characteristics : the number of messages, the time durations and the interlink times can be fitted using power and lognormal laws with suitable scales and parameters; for the interlink time, the analysis is done using the temporal delta density inspired by the delta density introduced by Viard and Latapy. This similarity between the characteristics of mailing lists also applies to the structure of dominant groups. For the time evolution of the number of messages, GnuPG exhibits a particular behavior. The interpretation of the different parameters gives very interesting insights into the membership and the type of topics covered by the mailing lists. The analysis carried out here and similar studies cited in this paper can therefore be considered as a first step towards the designing of building blocks for monitoring mailing lists.}, DOI = {10.1109/BigDataCongress.2015.119}, ISSN = {2379-7703}, ISBN = {978-1-4673-7278-7}, Unique-ID = {WOS:000380443700109}, } @article{ WOS:000302298900022, Author = {Bonnal, Raoul J.

Despite the substantive economic and efficiency-related implications of OSS adoption, there is surprisingly little research into the determinants of the diffusion of OSS across public sector jurisdictions. In this article we explore the variation in OSS adoption among Dutch local administrations. The Dutch central government adopted a policy to stimulate the use of OSS in the public sector, but the non-mandatory character of the policy resulted in great differences in the degree of adoption of OSS at the local level. Using data from a new survey of municipalities in the Netherlands and proportional odds statistical models to analyze the data, we show that the degree of OSS adoption crucially depends on the presence of boundary spanners and political commitment within the local government On the other hand, oft-suspected factors like financial stress and jurisdiction size have no discernible effects. Our findings have implications for understanding the spread of OSS in the public sector and for public policies designed to encourage OSS diffusion.

Recreation-grade side-scan sonar systems are increasingly used to aid scientific inquiries in aquatic environments due to their relative low-cost, ease of operation, low-weight, and ease of mounting on a variety of vessels. However, existing procedures and software for post-processing these data are either limited, closed source, or fail on data from new sonar models, limiting the development of reproducible workflows. Here, we present PING-Mapper, an open-source and freely available side-scan sonar post-processing toolset for processing and mapping sonar recordings from popular Humminbird instruments. The modular software automatically: (a) decodes sonar recordings from any Humminbird system, (b) exports ping attributes from every sonar channel, (c) uses sonar sensor depth for water column removal, and (d) exports sonogram tiles and georectified mosaics. Sonar channels are processed in parallel for quick decoding and metadata extraction. Major processing wokflows, including georectification and image export, are optimized to scale with computing resources. The software has been extensively tested using data from several rivers of varying character and distribution of depths, but could also be used in estuarine and lacustrine environments. Usage of PING-Mapper is illustrated in three case studies focused on mapping large woody debris, bathymetric mapping, and visual interpretation and mapping of substrates for selected reaches of the Pearl and Pascagoula river systems in Mississippi. Plain Language Summary Side-scan sonar instruments provide a way to survey and visualize the bottom of rivers, lakes, or oceans. Since the early 2000s, companies catering predominantly to anglers have manufactured recreation-grade side-scan sonar systems to aid fishermen in locating fish and identifying potential hazards. Scientists seeking to understand and manage aquatic habitats used these systems to create grayscale images of water bottoms because they are inexpensive, easy to operate, and require minimal mounting equipment on the boat. Software has been created by companies to process these data, but the underlying processing workflow and computer code are not publicly available, making it difficult to reproduce and compare results across studies. Other publicly available approaches and software are either outdated, not maintained, or not free. That is why we made PING-Mapper, a freely available software developed in an increasingly popular programming language called Python. We designed the software to work on any computer to export the data sets quickly and efficiently. The scientific use of exported data sets is demonstrated with three case studies focused on locating and mapping targets (specifically large trees and branches), creating depth maps, and visually discerning the distributions of common substrates, such as sand and cobble.}, DOI = {10.1029/2022EA002469}, Article-Number = {e2022EA002469}, EISSN = {2333-5084}, ResearcherID-Numbers = {Bodine, Cameron/JGD-0758-2023 Buscombe, Daniel/F-6283-2011 Best, Rebecca J/D-2934-2013 }, ORCID-Numbers = {Best, Rebecca J/0000-0003-2103-064X Bodine, Cameron/0000-0002-1623-3920 Buscombe, Daniel/0000-0001-6217-5584 Redner, Jennylyn/0000-0003-2408-0482}, Unique-ID = {WOS:000855279500001}, } @article{ WOS:000754321700005, Author = {Palys, Marcin}, Title = {The role of open source software in the process of implementing social innovation in SMEs}, Journal = {E-MENTOR}, Year = {2021}, Number = {5}, Pages = {45-52}, Abstract = {Nowadays, small and medium-sized enterprises (further SME) look for ways to overcome pressing social problems.

In addition, the issues fixing growth behavior is viewed as a function of continuation time of the software in the field environment and amount of uncertainty or complexity present in the source code. Therefore, a two-dimensional function called Cobb-Douglas production function is applied to model the intensity function of the issues fixing rate. Furthermore, the rate of fixing the different issue types is considered variable that may alter after certain time points. Thus, this study incorporates the concept of multiple change-points to predict and assess the fixing behavior of issues in the software system.

Because third-party firms can also strategically contribute to OSS and compete in the services market, the nature of competition between OSS constituents and proprietary software firms can be complex. Moreover, their incentives are likely influenced by the licensing schemes that govern OSS. We study a three-player game and examine how open-source licensing affects competition among an open-source originator, an open-source contributor, and a proprietor competing in an enterprise software market. In this regard, we examine (1) how quality investments and prices are endogenously determined in equilibrium, (2) how license restrictiveness impacts equilibrium investments and the quality of offerings, and (3) how license restrictiveness affects consumer surplus and social welfare. Although some in the open-source community often advocate restrictive licenses such as theGNUGeneral Public License because it is not always in the best interest of the originator for the contributor to invest greater development effort, such licensing can actually be detrimental to both consumer surplus and social welfare when it exacerbates this incentive conflict. We find such an outcome in markets characterized by software providers with similar development capabilities yet cast in favor of the proprietor. In contrast, when these capabilities either become more dispersed or remain similar but tilt in favor of open source, a more restrictive license instead encourages greater effort from the OSS contributor, leads to higher OSS quality, and provides a larger societal benefit.}, DOI = {10.1287/mnsc.2020.3674}, ISSN = {0025-1909}, EISSN = {1526-5501}, ResearcherID-Numbers = {Chen, Wei/KRP-2334-2024 }, ORCID-Numbers = {Chen, Wei/0000-0002-0963-7839}, Unique-ID = {WOS:000651625200020}, } @article{ WOS:000591374900001, Author = {Jadidoleslam, Navid and Goska, Radoslaw and Mantilla, Ricardo and Krajewski, Witold F.}, Title = {Hydrovise: A non-proprietary open-source software for hydrologic model and data visualization and evaluation}, Journal = {ENVIRONMENTAL MODELLING \& SOFTWARE}, Year = {2020}, Volume = {134}, Month = {DEC}, Abstract = {The authors developed a non-proprietary web-browser based open-source software that allows users to visualize and evaluate hydrologic space-time data in an interactive environment.

By knowing this licensing effect through scientific publications and their experience, project managers became able to act strategically, loosening up the restrictions associated with their source code due to sponsor interests, for example; or the contrary, tightening restrictions up to guarantee source code openness, adhering to the ``forever free{''} strategy. But, have project managers behaved strategically like that, changing their projects license? Up to this paper, we did not know if and what types of changes in these legal allowances project managers have made and, more importantly, whether such managerial interventions are associated with variations in intervened project attractiveness (i.e., related to their numbers of web hits, downloads and members). This paper accomplishes these two goals and demonstrates that: 1) managers of free and open source software projects do change the distribution rights of their source code through a change in the (group of) license(s) adopted; and 2) variations in attractiveness are associated with the strategic choice of a licensing schema. To reach these conclusions, a unique dataset of open source projects that have changed license was assembled in a comparative form, analyzing intervened projects over its monthly periods of different licenses. Based on a sample of more than 3500 active projects over 44 months obtained from the FLOSSmole repository of Sourceforge.net, 756 projects that had changed their source code distribution allowances and restrictions were identified and analyzed. A dataset on these projects' type of changes was assembled to enable a descriptive and exploratory analysis of the types of license interventions observed over a period of almost four years anchored on projects' attractiveness. More than 35 types of interventions were detected. The results indicate that variations in attractiveness after a license intervention are not symmetric; that is, if a change from license schema A to B is beneficial to attractiveness, a change from B to A is not necessarily prejudicial. This and other interesting findings are discussed in detail. In general, the results here reported support the current literature knowledge that the restrictions imposed by the license on the source code distribution are associated with market success vis-a-vis project attractiveness, but they also suggest that the state-of-the-science is superficial in terms of what is known about why these differences in attractiveness can be observed. The complexity of the results indicates to free software managers that no licensing schema should be seen as the right one, and its choice should be carefully made, considering project strategic goals as perceived relevant to stakeholders of the application and its production. These conclusions create awareness of several limitations of our current knowledge, which are discussed along with guidelines to understand them deeper in future research endeavors.}, DOI = {10.1186/s13174-017-0062-3}, Article-Number = {11}, ISSN = {1867-4828}, EISSN = {1869-0238}, ResearcherID-Numbers = {Santos, Carlos/A-8821-2013 }, ORCID-Numbers = {Santos, Carlos Denner dos/0000-0002-4481-0115}, Unique-ID = {WOS:000407207700001}, } @inproceedings{ WOS:000400303700027, Author = {Fernandesand, Sara and Barbosa, Luis Soares}, Editor = {Novotna, J and Jancarik, A}, Title = {Collaborative Environments in Software Engineering Teaching: A FLOSS Approach}, Booktitle = {PROCEEDINGS OF THE 15TH EUROPEAN CONFERENCE ON E-LEARNING (ECEL 2016)}, Series = {Proceedings on the European Conference of e-Learning}, Year = {2016}, Pages = {201-206}, Note = {15th European Conference on E-Learning (ECEL), Charles Univ, Prague, CZECH REPUBLIC, OCT 27-28, 2016}, Abstract = {Open development has emerged as a method for creating versatile and complex products through free collaboration of individuals.

Free software communities can be considered communities of practice, since they aggregate people interested in donating and collecting, that is, sharing knowledge about free software. According to the literature, the donation and collection of knowledge are motivated by different factors and these motivations may vary depending on the context. Free software communities may include members from different countries and backgrounds, which can make keeping such communities active and vigorous a challenge. This study aims to identify the motivations for knowledge sharing behaviour that are susceptible to leadership actions in free software communities. The research was carried out in three phases. First, a qualitative study involving twenty semi-structured interviews was conducted among members of a free software community, who suggested sixteen motivations for knowledge sharing behaviour. These motivations were then organized into three groups, each with a specific focus: three motivations only influence knowledge collection and focus on the knowledge itself; nine motivations only influence knowledge donation and focus on the individual; and four motivations influence both knowledge collection and knowledge donation, and focus on the relationships among individuals. After that, based on the groups of motivation identified in the previous phase, five leaders from different communities of practice were interviewed with the aim of identifying the main motivations that would be susceptible to their actions, which were knowledge quality, ease of access to knowledge, recognition, community support for knowledge sharing, learning and professional reasons. Finally, these six main motivations indicated by the leaders were tested in a quantitative phase involving 260 members of different free software communities. The results show that learning and ease of access to knowledge influence knowledge collection; recognition, community support for knowledge sharing and knowledge collection influence knowledge donation; and professional reasons influence both knowledge collection and knowledge donation in the context of free software communities.}, ISSN = {2048-8963}, ISBN = {978-1-910810-47-7}, ResearcherID-Numbers = {Balle, Andrea/O-7855-2016 Oliveira, Mirian/IZQ-0495-2023 Oliveira, Mirian/B-5090-2010 }, ORCID-Numbers = {Oliveira, Mirian/0000-0002-5498-0329 Balle, Andrea/0000-0003-2521-5342}, Unique-ID = {WOS:000371802400010}, } @inproceedings{ WOS:000247319400038, Author = {Schofield, Andrew and Cooper, Grahame S.}, Editor = {Feller, J and Fitzgerald, B and Scacchi, W and Sillitti, A}, Title = {Levels of formality in FOSS communities}, Booktitle = {OPEN SOURCE DEVELOPMENT, ADOPTION AND INNOVATION}, Series = {International Federation for Information Processing}, Year = {2007}, Volume = {234}, Pages = {337+}, Note = {3rd International Conference on Open Source Systems (OSS 2007), Limerick, IRELAND, JUN 11-14, 2007}, Organization = {IFIP WG2 13}, Abstract = {One of the aspects of Free and Open Source Software (FOSS) which may act as a significant deterrent to its adoption, is the method used to collaboratively develop the software and provide support through the use of communities.

The method can, however, seem very disorgamsed especially when compared with traditional proprietary development styles. A key difference between these two development approaches lies in the management of projects, and perhaps as a consequence, in the level of formality in the community environment.

The present research aims to introduce a new architecture proposal for migrating traditional (automation) to smart (digitization) factories, implemented through open-source software. The proposed architecture is integrated, for the first time, by the interconnection of six main elements: cyber-physical systems, edge computing, artificial intelligence, cloud computing, data analytics, and cybersecurity; the research describes in detail their definitions, sub-elements, the interconnection between elements, and the minimum requirements for implementation. The test of the proposed smart factory was done through a scale smart factory pilot testing for a pick and place process, where the assembly of wood pieces from the geometric Tangram's puzzle was required; for this reason, the pilot testing includes a six-degree-of-freedom robot arm, a conveyor, a vision system, and a storage area. The case study conducted in this research allowed the assembly of four puzzles (fish, house, rocket, and swan) that were assembled with four different batches of pieces. The implementation allowed testing flexibility and adaptability. The final assembly reports included the status of assembly, the number of pieces assembled, the number of pieces stored, the assembly sequence, and the assembly time. Similarly, the development of the SCADA system allowed asset control as well as asset monitoring. The KPIs of the assembly process measured productivity (OTD) and time tracking (ATCT and TA) of the 16 tests, founding that the interconnection and digitization of the scale manufacturing cell were fully integrated and allowed repeatability; the proposed SF architecture represents an alternative for the small and medium automated factories to achieve interconnection and digitization, and it is ready to be tested in a more complex scenario.}, DOI = {10.1109/ACCESS.2023.3316116}, ISSN = {2169-3536}, ORCID-Numbers = {CENTENO TELLEZ, ADOLFO/0000-0001-8728-2028 Fortoul-Diaz, Jesus Anselmo/0000-0002-5412-2279}, Unique-ID = {WOS:001071737500001}, } @inproceedings{ WOS:000290887300023, Author = {Ping, Chen and Hua, Dong Xing and Xu, Zhou}, Editor = {Hu, BG and Xie, XY and Saguez, C and Gomez, C}, Title = {Design and Implementation of the Communication Experiments Based on Open Source Software SCILAB/SCICOS}, Booktitle = {PROCEEDINGS 2009 IEEE INTERNATIONAL WORKSHOP ON OPEN-SOURCE SOFTWARE FOR SCIENTIFIC COMPUTATION}, Year = {2009}, Pages = {131-134}, Note = {1st International Workshop on Open-source Software for Scientific Computation, Guiyang, PEOPLES R CHINA, SEP 18-20, 2009}, Organization = {INRIA; IEEE; Chinese Acad Sci, Inst Automat; SciLab; Republ Francaise}, Abstract = {As simulation softwares are playing an essential role in communication theory experiment, it is necessary that a platform should include sufficient simulation blocks, test cases and detailed help files.

UISCEmod was evaluated at 16 representative sites in Ireland obtaining Nash-Sutcliffe Efficiency (NSE) and Kling-Gupta Efficiency (KGE) above 0.85 for both stage and volume time series for most of the sites, showing its potential for covering the need for a simple, pragmatic, and flexible framework for modelling water levels in ephemeral karstic wetlands with relatively limited input data requirements.}, DOI = {10.1016/j.envsoft.2023.105761}, EarlyAccessDate = {JUN 2023}, Article-Number = {105761}, ISSN = {1364-8152}, EISSN = {1873-6726}, ResearcherID-Numbers = {Campanya, Joan/I-4806-2016}, ORCID-Numbers = {Naughton, Owen/0000-0001-9616-0022 Campanya, Joan/0000-0001-5330-7223}, Unique-ID = {WOS:001034636100001}, } @article{ WOS:000809199200001, Author = {Gabriel, Leandro and Almeida, Helena and Avelar, Marta and Sarmento, Bruno and das Neves, Jose}, Title = {MPTHub: An Open-Source Software for Characterizing the Transport of Particles in Biorelevant Media}, Journal = {NANOMATERIALS}, Year = {2022}, Volume = {12}, Number = {11}, Month = {JUN}, Abstract = {The study of particle transport in different environments plays an essential role in understanding interactions with humans and other living organisms. Importantly, obtained data can be directly used for multiple applications in fields such as fundamental biology, toxicology, or medicine. Particle movement in biorelevant media can be readily monitored using microscopy and converted into time-resolved trajectories using freely available tracking software. However, translation into tangible and meaningful parameters is time consuming and not always intuitive. We developed new software-MPTHub-as an open-access, standalone, user-friendly tool for the rapid and reliable analysis of particle trajectories extracted from video microscopy. The software was programmed using Python and allowed to import and analyze trajectory data, as well as to export relevant data such as individual and ensemble time-averaged mean square displacements and effective diffusivity, and anomalous transport exponent. Data processing was reliable, fast (total processing time of less than 10 s), and required minimal memory resources (up to a maximum of around 150 MB in random access memory). Demonstration of software applicability was conducted by studying the transport of different polystyrene nanoparticles (100-200 nm) in mucus surrogates. Overall, MPTHub represents a freely available software tool that can be used even by inexperienced users for studying the transport of particles in biorelevant media.}, DOI = {10.3390/nano12111899}, Article-Number = {1899}, EISSN = {2079-4991}, ResearcherID-Numbers = {Neves, José/J-8369-2013 Almeida, Helena/AAE-8202-2022 Sarmento, Bruno/J-6265-2013}, ORCID-Numbers = {Gabriel, Leandro/0000-0003-3454-2118 Almeida, Helena/0000-0002-7434-0839 Sarmento, Bruno/0000-0001-5763-7553}, Unique-ID = {WOS:000809199200001}, } @article{ WOS:000577246500001, Author = {Keilegavlen, Eirik and Berge, Runar and Fumagalli, Alessio and Starnoni, Michele and Stefansson, Ivar and Varela, Jhabriel and Berre, Inga}, Title = {PorePy: an open-source software for simulation of multiphysics processes in fractured porous media}, Journal = {COMPUTATIONAL GEOSCIENCES}, Year = {2021}, Volume = {25}, Number = {1}, Pages = {243-265}, Month = {FEB}, Abstract = {Development of models and dedicated numerical methods for dynamics in fractured rocks is an active research field, with research moving towards increasingly advanced process couplings and complex fracture networks. The inclusion of coupled processes in simulation models is challenged by the high aspect ratio of the fractures, the complex geometry of fracture networks, and the crucial impact of processes that completely change characteristics on the fracture-rock interface. This paper provides a general discussion of design principles for introducing fractures in simulators, and defines a framework for integrated modeling, discretization, and computer implementation. The framework is implemented in the open-source simulation software PorePy, which can serve as a flexible prototyping tool for multiphysics problems in fractured rocks. Based on a representation of the fractures and their intersections as lower-dimensional objects, we discuss data structures for mixed-dimensional grids, formulation of multiphysics problems, and discretizations that utilize existing software. We further present aPythonimplementation of these concepts in the PorePy open-source software tool, which is aimed at coupled simulation of flow and transport in three-dimensional fractured reservoirs as well as deformation of fractures and the reservoir in general. We present validation by benchmarks for flow, poroelasticity, and fracture deformation in porous media. The flexibility of the framework is then illustrated by simulations of non-linearly coupled flow and transport and of injection-driven deformation of fractures.

Therefore, this paper studies project capabilities as potential predictors of OSS project performance. The data, gathered from 607 OSS projects over time (in two snap-shots), were consistent with Dynamic Capability Theory (DCT). In other words, the results showed that in order to achieve higher project performance, OSS projects need to have strong capabilities in terms of proactive and efficient defect-removal as well as proactive and efficient functionality-enhancement.

The structure of the mitral and tricuspid valves in biventricular hearts has previously been shown to be associated with valve dysfunction. However, the three-dimensional (3D) structure of the entire unrepaired CAVC valve has not been quantified. Understanding the 3D structure of the CAVC may inform optimized repair.Methods: Novel open-source work flows were created in SlicerHeart for the modeling and quantification of CAVC valves on the basis of 3D echocardiographic images. These methods were applied to model the annulus, leaflets, and papillary muscle (PM) structure of 35 patients (29 with trisomy 21) with CAVC using trans -thoracic 3D echocardiography. The mean leaflet and annular shapes were calculated and visualized using shape analysis. Metrics of the complete native CAVC valve structure were compared with those of normal mitral valves using the Mann-Whitney U test. Associations between CAVC structure and atrioventricular valve regurgitation were analyzed.Results: CAVC leaflet metrics varied throughout systole. Compared with normal mitral valves, the left CAVC PMs were more acutely angled in relation to the annular plane (P < .001). In addition, the anterolateral PM was laterally and inferiorly rotated in CAVC, while the posteromedial PM was more superiorly and laterally rotated, relative to normal mitral valves (P < .001). Lower native CAVC atrioventricular valve annular height and annular height-to-valve width ratio before repair were both associated with moderate or greater left atrio-ventricular valve regurgitation after repair (P < .01).Conclusions: It is feasible to model and quantify 3D CAVC structure using 3D echocardiographic images. The results demonstrate significant variation in CAVC structure across the cohort and differences in annular, leaflet, and PM structure compared with the mitral valve. These tools may be used in future studies to catalyze future research intended to identify structural associations of valve dysfunction and to optimize repair in this vulnerable and complex population.

In this work large-scale empirical comparisons of thirteen classifiers over seven open source datasets were conducted followed by extensive statistical tests and post hoc analysis to establish the confidence on the performance of one ML technique over another.

We distinguish between internal contributors affiliated with target firms and external contributors from the community, and examine how they respond to technological acquisitions differently. Theoretically, we examine how technological acquisition influences contributors' uncertainty about project quality through a signaling effect and influences their uncertainty about project continuity through potential resource combination. We connect uncertainties with contributors' motivations to theorize their responses to acquisitions. Empirically, we find that external contributors contribute more actively to both target firms' sponsored projects and other projects in the OSS community after acquisitions, which contrast with the adverse effects of acquisitions observed in traditional corporate innovation. Although internal contributors reduce contributions to target firms' sponsored projects after acquisitions, they increase contributions to other OSS projects in the community. We also find that the acquirer's OSS experience and the project similarity between the acquirer and the target drive both external and internal contributors to shift their development efforts to the acquirer's projects and other projects in the OSS community. By examining these effort shifts in OSS contributions, our study generates unique theoretical insights about the impacts of technological acquisitions in the OSS context and important practical implications for acquirers, target firms, and the general OSS community.}, DOI = {10.1287/isre.2021.1086}, EarlyAccessDate = {DEC 2021}, ISSN = {1047-7047}, EISSN = {1526-5536}, ResearcherID-Numbers = {Chen, Wei/KRP-2334-2024 }, ORCID-Numbers = {Chen, Wei/0000-0002-0963-7839}, Unique-ID = {WOS:000734914100001}, } @article{ WOS:000655363900012, Author = {Ramirez-Mora, Sandra L. and Oktaba, Hanna and Gomez-Adorno, Helena and Sierra, Gerardo}, Title = {Exploring the communication functions of comments during bug fixing in Open Source Software projects}, Journal = {INFORMATION AND SOFTWARE TECHNOLOGY}, Year = {2021}, Volume = {136}, Month = {AUG}, Abstract = {Context: Bug fixing is a frequent and important task in Open Source Software (OSS) development and involves the communication of messages, which can serve for multiple purposes and affect the efficiency and effectiveness of corrective software activities. Objective: This work is aimed at studying the communication functions of bug comments and their associations with fast and complete bug fixing in OSS development. Method: Over 500K comments and 89K bugs of 100 OSS projects were extracted from three Issue Tracking Systems. Six thousand comments were manually tagged to create a corpus of communication functions. The extracted comments were automatically tagged using machine learning algorithms and the corpus of communication functions. Statistical and correlation analyses were performed and the most frequent comments communicated during fast and successful bug fixing were identified. Results: Significant differences in the distribution of comments of fixed and not fixed bugs were found. Variations in the distribution of comments of bugs with different fixing time were also found. Referential comments that provided objective information were found to be the most frequent messages. Results showed that the percentages of conative and emotive comments are greater when bugs are resolved without the requested fixes and when fixes are implemented in a long time. Conclusion: Associations between communication functions and bug fixing exist. The results of this work could be used to improve corrective tasks in OSS development and some other specific linguistic aspects should be studied in detail in OSS communities.}, DOI = {10.1016/j.infsof.2021.106584}, EarlyAccessDate = {APR 2021}, Article-Number = {106584}, ISSN = {0950-5849}, EISSN = {1873-6025}, ResearcherID-Numbers = {Gómez Adorno, Helena/E-6151-2018 Sierra, Gerardo/J-3737-2016 }, ORCID-Numbers = {Sierra, Gerardo/0000-0002-6724-1090 Gomez Adorno, Helena/0000-0002-6966-9912 Oktaba, Hanna/0000-0003-2852-4490}, Unique-ID = {WOS:000655363900012}, } @article{ WOS:001242169100001, Author = {Tong, Defu and Yi, Xiongwei and Tan, Fei and Jiao, Yuyong}, Title = {MEG3D--An Open-Source Software for DFN Model and 3D Numerical Manifold Elements Generation}, Journal = {COMPUTERS AND GEOTECHNICS}, Year = {2024}, Volume = {172}, Month = {AUG}, Abstract = {Numerical manifold method (NMM) has shown its ability to solve continuous and discontinuous deformation problems in a unified framework.

Through statistical analysis of time to first response and sentiment analysis of that response to a new contributor's issue, we found that there is a difference in both the speed and content of responses to new contributors' issues as opposed to those of established contributors.

Researchers typically test hypotheses on the controlling torques via forward computer models, which allow accepting or rejecting hypotheses on the basis of the fit of model-output plate velocities to kinematic reconstructions. Such models typically require a significant amount of input information (e.g., tectonic boundaries, structure of the lithosphere, lateral variations of rheology, among others) to appropriately model the tectonic system, and obtain sufficiently-realistic realizations of plate motions. Alternatively, the inverse problem approach takes the difference between the plate torque-balance at two distinct moments in time. This results in an equation in which (a) torques that have not varied through time are canceled out and (b) torques that instead have varied through time are linked to the resulting plate-motion change through a term that accounts for the plate shape and the rheology of the underlying asthenosphere. This approach sacrifices the capability to describe the different individual forces/torques acting upon a plate. Instead, it focuses on determining torque temporal variations, which significantly reduces the amount of input knowledge required. In this technical note we introduce MYRIAM, an open-source software that implements such an inverse approach. MYRIAM takes plate-motion temporal changes, and outputs an estimate of the torque variation required upon a plate to generate the input kinematic change. MYRIAM is released as an open-source repository hosted at GitHub, complete with source code and executable files for Windows and Unix-based operating systems. Plain Language Summary The outermost layer of the Earth, known as the lithosphere, is fragmented into plates that are in motion relative to each other. Through geological history, the motion of tectonic plates did not remain steady, and in fact important changes are now known to have occurred relatively fast, within a few million years. By virtue of Newton's laws of motion, these changes are all necessarily caused by the variation in one or more forces acting upon the plates, and therefore disrupt their force balance. Changing the motion of a plate is not an easy feat-for plates it requires overcoming the frictional resistance exerted by the underlying asthenosphere, a low-viscosity layer beneath the plates. The resulting motion change will depend on (a) the mechanical properties of the asthenosphere and (b) the amount of plate surface interacting with said asthenosphere (i.e., the basal area of the plate). All these considerations are taken into account by MYRIAM, an open-source, computationally-inexpensive software that estimates the force/torque variations required to produce a given change of plate motion.}, DOI = {10.1029/2023GC011095}, Article-Number = {e2023GC011095}, EISSN = {1525-2027}, ORCID-Numbers = {Martin de Blas, Juan Ignacio/0000-0002-9190-9329 Espinoza Fernandez, Valentina Soledad/0000-0001-6445-5643}, Unique-ID = {WOS:001158168100001}, } @article{ WOS:000336410100006, Author = {de Laat, Paul B.}, Title = {From open-source software to Wikipedia: `Backgrounding' trust by collective monitoring and reputation tracking}, Journal = {ETHICS AND INFORMATION TECHNOLOGY}, Year = {2014}, Volume = {16}, Number = {2}, Pages = {157-169}, Month = {JUN}, Abstract = {Open-content communities that focus on co-creation without requirements for entry have to face the issue of institutional trust in contributors. This research investigates the various ways in which these communities manage this issue. It is shown that communities of open-source software-continue to-rely mainly on hierarchy (reserving write-access for higher echelons), which substitutes (the need for) trust. Encyclopedic communities, though, largely avoid this solution. In the particular case of Wikipedia, which is confronted with persistent vandalism, another arrangement has been pioneered instead. Trust (i.e. full write-access) is `backgrounded' by means of a permanent mobilization of Wikipedians to monitor incoming edits. Computational approaches have been developed for the purpose, yielding both sophisticated monitoring tools that are used by human patrollers, and bots that operate autonomously. Measures of reputation are also under investigation within Wikipedia; their incorporation in monitoring efforts, as an indicator of the trustworthiness of editors, is envisaged. These collective monitoring efforts are interpreted as focusing on avoiding possible damage being inflicted on Wikipedian spaces, thereby being allowed to keep the discretionary powers of editing intact for all users. Further, the essential differences between backgrounding and substituting trust are elaborated. Finally it is argued that the Wikipedian monitoring of new edits, especially by its heavy reliance on computational tools, raises a number of moral questions that need to be answered urgently.}, DOI = {10.1007/s10676-014-9342-9}, ISSN = {1388-1957}, EISSN = {1572-8439}, ResearcherID-Numbers = {de+Laat, Paul/AAC-8836-2022}, Unique-ID = {WOS:000336410100006}, } @inproceedings{ WOS:000242043700011, Author = {Baravalle, Andres and Chambers, Sarah and North, Siobhan and Holcombe, Mike}, Book-Group-Author = {INSTICC}, Title = {Open source software in the desktop: The perspective of the public administrations in UK}, Booktitle = {WEBIST 2006: Proceedings of the Second International Conference on Web Information Systems and Technologies: SOCIETY, E-BUSINESS AND E-GOVERNMENT / E-LEARNING}, Year = {2006}, Pages = {39-44}, Note = {2nd International Conference on Web Information Systems and Technologies, Business Sch Setubal, Setubal, PORTUGAL, APR 11-13, 2006}, Organization = {Inst Syst \& Technol Informat Control \& Commun; Setubal Polytech Inst; Object Management Grp}, Abstract = {Open Source could potentially play an important role in e-Government.

In this paper, we investigate whether code issues that are detected by SpotBugs persist in software code, or if they get removed. We chose SpotBugs because it is one of the best-known and most used static analyzers. Method. We carried out an empirical study on five open-source Java programs and took into account two versions of each of them, to check whether the issues signaled by SpotBugs on the older version had been removed by the time the newer version was released. A total of 1,006 issues were signaled by SpotBugs. Results. Our results show that about half of the issues signaled disappeared between the two versions, but the correction rate was uneven across projects. Issues about the correctness of software code were more likely to be no longer present in the newer version than other types of warnings. Conclusions. Further investigations are required, to understand why some projects appear more active than others in correcting SpotBugs issues, and why very few high-severity warnings were observed in the analyzed code. Nonetheless, the fact that about half of the issues flagged by SpotBugs were removed indicates that the tool is effective in detecting incorrect or otherwise problematic code.}, DOI = {10.1007/978-3-030-58793-2\_12}, ISSN = {1865-0929}, EISSN = {1865-0937}, ISBN = {978-3-030-58792-5; 978-3-030-58793-2}, ResearcherID-Numbers = {TOSI, DAVIDE/AAI-1310-2020 Lavazza, Luigi/AAF-5323-2020 }, ORCID-Numbers = {TOSI, DAVIDE/0000-0003-3815-2512 Lavazza, Luigi/0000-0002-5226-4337}, Unique-ID = {WOS:001359447500012}, } @article{ WOS:000428461600003, Author = {Hilton, Rod and Gethner, Ellen}, Title = {Predicting Code Hotspots in Open-Source Software from Object-Oriented Metrics Using Machine Learning}, Journal = {INTERNATIONAL JOURNAL OF SOFTWARE ENGINEERING AND KNOWLEDGE ENGINEERING}, Year = {2018}, Volume = {28}, Number = {3}, Pages = {311-331}, Month = {MAR}, Abstract = {Software engineers are able to measure the quality of their code using a variety of metrics that can be derived directly from analyzing the source code.

However, no software package exists to process mpMRI data of the spinal cord.

To turn massive datasets into predictive quantitative frameworks, the field needs software solutions for systematic integration of data into realistic, multiscale models.

Leveraging the SONATA file format and existing software such as NEURON, NEST, and others, BMTK offers a consistent user experience across multiple levels of resolution. It permits highly sophisticated simulations to be set up with little coding required, thus lowering entry barriers to new users. We illustrate successful applications of BMTK to large-scale simulations of a cortical area.

Bead-based multiplexed bioassays have many technical advantages, including near solution-phase kinetics, small sample volume requirements, many within-assay replicates to reduce measurement error, and, for some bead materials, the ability to synthesize analytes directly on beads via solid-phase synthesis. To allow bead-based multiplexing, analytes can be synthesized on spectrally encoded beads with a 1:1 linkage between analyte identity and embedded codes. Bead-bound analyte libraries can then be pooled and incubated with a fluorescently-labeled macromolecule of interest, allowing downstream quantification of interactions between the macromolecule and all analytes simultaneously via imaging alone. Extracting quantitative binding data from these images poses several computational image processing challenges, requiring the ability to identify all beads in each image, quantify bound fluorescent material associated with each bead, and determine their embedded spectral code to reveal analyte identities. Here, we present a novel open-source Python software package (the mrbles analysis package) that provides the necessary tools to: (1) find encoded beads in a bright-field microscopy image; (2) quantify bound fluorescent material associated with bead perimeters; (3) identify embedded ratiometric spectral codes within beads; and (4) return data aggregated by embedded code and for each individual bead. We demonstrate the utility of this package by applying it towards analyzing data generated via multiplexed measurement of calcineurin protein binding to MRBLEs (Microspheres with Ratiometric Barcode Lanthanide Encoding) containing known and mutant binding peptide motifs. We anticipate that this flexible package should be applicable to a wide variety of assays, including simple bead or droplet finding analysis, quantification of binding to non-encoded beads, and analysis of multiplexed assays that use ratiometric, spectrally encoded beads.}, DOI = {10.1371/journal.pone.0203725}, Article-Number = {e0203725}, ISSN = {1932-6203}, ResearcherID-Numbers = {Fordyce, Polly/AAY-6365-2020 Harink, Björn/AAA-1708-2020 }, ORCID-Numbers = {Fordyce, Polly/0000-0002-9505-0638 Thorn, Kurt/0009-0007-5407-8240 Harink, Bjorn/0000-0003-1283-0151}, Unique-ID = {WOS:000462000400001}, } @inproceedings{ WOS:000503459500009, Author = {Popescu, Dimitrie C. and Musson, John and Popescu, Otilia}, Book-Group-Author = {IEEE}, Title = {Empirical Characterization of Man-Made Impulsive Noise Using Open-Source Software Defined Radio Platforms}, Booktitle = {2019 INTERNATIONAL SYMPOSIUM ON SIGNALS, CIRCUITS AND SYSTEMS (ISSCS 2019)}, Year = {2019}, Note = {14th International Symposium on Signals, Circuits and Systems (ISSCS), Iasi, ROMANIA, JUL 11-12, 2019}, Organization = {IEEE; IEEE CAS; Gheorghe Asachi Tech Univ Iasi, Fac Elect Telecommunicat \& Informat Technol; IEEE Romania Sect CAS Chapter; Infineon; Silicon Serv; Microchip; Sitex 45 SRL; Continental}, Abstract = {With the widespread use of wireless systems in the modern society, every household, office, and even automobiles, now contain radio-frequency (RF) sources capable of producing interference.

The receiving gateway forwards the image data to the final destination again using the DICOM-Protocol. The gateway is based on Open Source software and runs under several operating systems.

We implemented a classic, pixel-by-pixel deconvolution approach to quantify T1-weighted contrast-enhanced dynamic MR imaging (DCE-MRI) perfusion data as an OsiriX plug-in. It features parallel computing capabilities and an automated reporting scheme for quality management. Furthermore, by our implementation design, it could be easily extendable to other perfusion algorithms. Obtained results are saved as DICOM objects and directly added to the patient study. The plug-in was evaluated on ten MR perfusion data sets of the prostate and a calibration data set by comparing obtained parametric maps (plasma flow, volume of distribution, and mean transit time) to a widely used reference implementation in IDL. For all data, parametric maps could be calculated and the plug-in worked correctly and stable. On average, a deviation of 0.032 +/- 0.02 ml/100 ml/min for the plasma flow, 0.004 +/- 0.0007 ml/100 ml for the volume of distribution, and 0.037 +/- 0.03 s for the mean transit time between our implementation and a reference implementation was observed. By using computer hardware with eight CPU cores, calculation time could be reduced by a factor of 2.5. We developed successfully an Open Source OsiriX plugin for T1-DCE-MRI perfusion analysis in a routine quality managed clinical environment. Using model-free deconvolution, it allows for perfusion analysis in various clinical applications.

State-of-the-art characterization of sample materials related to these fields, deploying high-end instrumentation, allows for gathering large quantities of molecular composition data. One established technological platform is ultrahigh-resolution mass spectrometry, e.g., Fourier-transform mass spectrometry (FT-MS). However, the huge amounts of data acquired in FT-MS often result in tedious data treatment and visualization. FT-MS analysis of complex matrices can easily lead to single mass spectra with more than 10,000 attributed unique molecular formulas. Sophisticated software solutions to conduct these treatment and visualization attempts from commercial and noncommercial origins exist. However, existing applications have distinct drawbacks, such as focusing on only one type of graphic representation, being unable to handle large data sets, or not being publicly available. In this respect, we developed a software, within the international complex matrices molecular characterization joint lab (IC2MC), named ``python tools for complex matrices molecular characterization{''} (PyC2MC). This piece of software will be open-source and free to use. PyC2MC is written under python 3.9.7 and relies on well-known libraries such as pandas, NumPy, or SciPy. It is provided with a graphical user interface developed under PyQt5. The two options for execution, (1) a user-friendly route with a prepacked executable file or (2) running the main python script through a Python interpreter, ensure a high applicability but also an open characteristic for further development by the community.

Our objective is to understand the discourse around discussions on such an attack, how it is received by the community, and whether developers respond to the attack in a timely manner. We study two notable protestware cases i.e., colors.js and es5-ext. Results indicate that protestware discussions are spread more quickly on the GitHub platform, while security vulnerabilities are faster on social media. By establishing a taxonomy of protestware discussions, we identify posts that express stances and provide technical mitigation instructions. We applied a thematic analysis to 684 protestware related posts to identify five major themes during the discussions: i. disseminate and response, ii. stance, iii. reputation, iv. communicative styles, v. rights and ethics. This work sheds light on the nuanced landscape of protestware discussions, offering insights for both researchers and developers into maintaining a healthy balance between the political or social actions of developers and the collective well-being of the open-source community.}, DOI = {10.1007/s10664-024-10599-6}, Article-Number = {56}, ISSN = {1382-3256}, EISSN = {1573-7616}, ResearcherID-Numbers = {Treude, Christoph/AAZ-6257-2021 }, ORCID-Numbers = {Fan, Youmei/0000-0001-9372-2966}, Unique-ID = {WOS:001399485500001}, } @incollection{ WOS:000417128000020, Author = {MacKellar, Bonnie K. and Sabin, Mihaela and Tucker, Allen B.}, Book-Author = {Yu, L}, Title = {Bridging the Academia-Industry Gap in Software Engineering: A Client-Oriented Open Source Software Projects Course}, Booktitle = {OVERCOMING CHALLENGES IN SOFTWARE ENGINEERING EDUCATION: DELIVERING NON-TECHNICAL KNOWLEDGE AND SKILLS}, Series = {Advances in Higher Education and Professional Development Book Series}, Year = {2014}, Pages = {373-396}, Abstract = {Too often, computer science programs offer a software engineering course that emphasizes concepts, principles, and practical techniques, but fails to engage students in real-world software experiences.

E-portfolios with mobile capabilities allow even more flexibility. However, the development or acquisition of ePortfolio software is often costly, and at the same time, commercially available systems may not sufficiently fit the institution's needs. The aim of this study was to design and evaluate an ePortfolio system with mobile capabilities using a commercially free and open source software solution. Methods: We created an online ePortfolio environment using the blogging software WordPress based on reported capability features of such software by a qualitative weight and sum method. Technical implementation and usability were evaluated by 25 medical students during their clinical training by quantitative and qualitative means using online questionnaires and focus groups. Results: The WordPress ePortfolio environment allowed students a broad spectrum of activities - often documented via mobile devices - like collection of multimedia evidences, posting reflections, messaging, web publishing, ePortfolio searches, collaborative learning, knowledge management in a content management system including a wiki and RSS feeds, and the use of aid tools for studying. The students' experience with WordPress revealed a few technical problems, and this report provides workarounds. The WordPress ePortfolio was rated positively by the students as a content management system (67 \% of the students), for exchange with other students (74 \%), as a note pad for reflections (53 \%) and for its potential as an information source for assessment (48 \%) and exchange with a mentor (68 \%). On the negative side, 74 \% of the students in this pilot study did not find it easy to get started with the system, and 63 \% rated the ePortfolio as not being user-friendly. Qualitative analysis indicated a need for more introductory information and training. Conclusions: It is possible to build an advanced ePortfolio system with mobile capabilities with the free and open source software WordPress. This allows institutions without proprietary software to build a sophisticated ePortfolio system adapted to their needs with relatively few resources. The implementation of WordPress should be accompanied by introductory courses in the use of the software and its apps in order to facilitate its usability.}, DOI = {10.1186/s12909-016-0678-1}, Article-Number = {157}, ISSN = {1472-6920}, ResearcherID-Numbers = {Peters, Harm/AAE-5643-2019 Breckwoldt, Jan/E-9309-2015 }, ORCID-Numbers = {Breckwoldt, Jan/0000-0003-1716-1970 Peters, Harm/0000-0003-1441-7512}, Unique-ID = {WOS:000377170900001}, } @inproceedings{ WOS:000258398700012, Author = {Gasser, Les and Scacchi, Walt}, Editor = {Russo, B and Damiani, E and Hissam, S and Lundell, B and Succi, G}, Title = {Towards a global research infrastructure for multidisciplinary study of Free/Open Source Software development}, Booktitle = {OPEN SOURCE DEVELOPMENT, COMMUNITIES AND QUALITY}, Series = {International Federation for Information Processing}, Year = {2008}, Volume = {275}, Pages = {143+}, Note = {4th International Conference on Open Source Systems held at the 20th World Computer Congress, Milan, ITALY, SEP 07-10, 2008}, Organization = {IFIP WG 2 3}, Abstract = {The Free/Open Source Software (F/OSS) research community is growing across and within multiple disciplines. This community faces a new and unusual situation. The traditional difficulties of gathering enough empirical data have been replaced by issues of dealing with enormous amounts of freely available public data from many disparate sources (online discussion forums, source code directories, bug reports, OSS Web portals, etc.). Consequently, these data are being discovered, gathered, analyzed, and used to support multidisciplinary research. However at present, no means exist for assembling these data under common access points and frameworks for comparative, longitudinal, and collaborative research across disciplines. Gathering and maintaining large F/OSS data collections reliably and making them usable present several research challenges. For example, current projects usually rely on direct access to, and mining of raw data from groups that generate it, and both of these methods require unique effort for each new corpus, or even for updating existing corpora.

However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS.

A major controlling factor on the ecology and distribution of vegetation and animal populations in these harsh arid systems is the abundance and distribution of water sources. Accordingly, extraction and redistribution of water at artificial water points across desert landscapes can constitute a real threat to local ecosystem dynamics. A major challenge in tackling this potential threat is identifying changes in the distribution of artificial water points through space and time, due to the difficulties of collecting such information at relevant spatial and temporal scales. We here investigate the potential for freely available satellite imagery to provide reliable information about the distribution of artificial water points using the Ouadi Rime-Ouadi Achim Faunal Reserve (OROAFR), Chad, as a case study. We reveal that Landsat 8 data combined with texture analysis can accurately detect these artificial landmarks across the heterogeneous environment of OROAFR; 75.68\% of artificial water points within the site were successfully identified and false positive detection rate was minimal at 7.69\%. The methodological framework developed for this work, based on the treatment of freely available satellite data using open source software, adds to other works attempting to help monitor threats to biodiversity in desert ecosystems, enabling up-to-date information on the level of anthropogenic activities in these habitats to be easily and regularly collected.}, DOI = {10.1002/rse2.5}, EISSN = {2056-3485}, ResearcherID-Numbers = {Pettorelli, Nathalie/AAW-8438-2021 Duncan, Clare/V-6005-2019 }, ORCID-Numbers = {Owen, Harry/0000-0002-4294-1728 Duncan, Clare/0000-0001-5315-2997 Pettorelli, Nathalie/0000-0002-1594-6208}, Unique-ID = {WOS:000448239100007}, } @inproceedings{ WOS:000325951400014, Author = {Sigama, Khuliso and Kalema, Billy Mathias and Kekwaletswe, Ray M.}, Book-Group-Author = {IEEE}, Title = {Utilizing Web 2.0 and Free Open Source Software to Advance E-Learning in Developing Countries}, Booktitle = {2012 E-LEADERSHIP CONFERENCE ON SUSTAINABLE E-GOVERNMENT AND E-BUSINESS INNOVATIONS (E-LEADERSHIP)}, Year = {2012}, Note = {1st E-Leadership Conference on Sustainable E-Government and E-Business Innovations, Univ Pretoria, Pretoria, SOUTH AFRICA, OCT 04-05, 2012}, Abstract = {E-Iearning success is dependent on effective and efficient delivery of teaching and learning contents electronically. New technological innovations have greatly facilitated e-learning and have made it conducive to those who can afford. Developed countries have significantly benefited from these innovations whereas developing economies are still battling with the many challenges that have hindered e-learning success. The advent of Web 2.0 and Free Open Source Software (FOSS) would have been seen as the breakthrough for the developing economies to embrace e-learning. However, many factors still impede the utilization of these technologies for e-learning. The major objective of this paper is to discuss the factors that hinder institutions from utilizing Web 2.0 and FOSS for e-learning. Content analysis was used to evaluate the factors that had been identified in literature and to tally them according to their frequency. 36 factors were deduced and analyzed using structural equation modeling (SEM) method. Results indicated that technological factors predominantly impact on the utilization of Web 2.0 and FOSS for e-learning.

This chapter uses coordination theory to analyze the bug fixing processes in the proprietary operating system development group of a large minicomputer manufacturer and for the Free/Libre Open Source Software Linux operating system kernel. Three approaches to identifying dependencies and coordination mechanisms are presented. Mechanisms analyzed include those for task assignment, resource sharing, and managing dependencies between modules of source code. The proprietary development organization assigned problem reports to engineers based on the module that appeared to be in error, because engineers only worked on particular modules. Alternative task assignment mechanisms include assignment to engineers based on workload or voluntary assignment, as in Linux. In the proprietary process, modules of source code were not shared but, rather, were ``owned{''} by one engineer, thus reducing the need for coordination. In Linux, where multiple developers can work on the same modules, alternative resource sharing mechanisms have been developed to manage source code. Finally, the proprietary developers managed dependencies between modules informally, relying on their personal knowledge of which other engineers used their code. The Linux process allows developers to change code in multiple modules, but emphasizes modularity to reduce the need to do so. By helping in the identification of dependencies in the bug fixing processes, drawing upon coordination theory streamlines bug fixing activities of a large mini-computer manufacturer and for the Free/Libre Open Source Software Linux operating system kernel.}, ISSN = {1554-6152}, ISBN = {978-0-7656-1191-8}, ResearcherID-Numbers = {Crowston, Kevin/C-6068-2008}, Unique-ID = {WOS:000283436500006}, } @inproceedings{ WOS:000719308400014, Author = {Onyango, Samuel and Steenvoorden, Emilie and Scholten, Joram and Jansen, Slinger}, Editor = {Gregory, P and Kruchten, P}, Title = {Assessing the Health of the Dark Web: An Analysis of Dark Web Open Source Software Projects}, Booktitle = {AGILE PROCESSES IN SOFTWARE ENGINEERING AND EXTREME PROGRAMMING - WORKSHOPS (XP 2021)}, Series = {Lecture Notes in Business Information Processing}, Year = {2021}, Volume = {426}, Pages = {125-134}, Note = {22nd International Conference on Agile Software Development (XP), ELECTR NETWORK, JUN 14-18, 2021}, Organization = {Agile Alliance}, Abstract = {A hidden part of the World Wide Web is known as the Dark Web, featuring websites that cannot be indexed by traditional search engines.

The goal of this research is to evaluate the health of the ecosystem through an assessment of Tor, I2P and GitHub. The Open Source Ecosystem Health Operationalization framework is used to help perform this assessment. Eight metrics from the framework are selected, which are measured using the data collected. Analysis of Tor and I2P metrics suggest that there has been an increase in Tor and I2P user activity in the recent past. Added knowledge, spin offs and forks and usage indicate active participation and interest in Tor and I2P. There has also been an increase in the number of active GitHub Dark Web projects. However, these GitHub projects are not well-connected and only a small number of projects have a large number of contributors. There is some variety among the GitHub software projects.

However, to quantitatively measure the growth rate of genetically different fungal strains or strains under different environmental/growth conditions (pH, temperature, carbon and nitrogen sources, antibiotics, etc.) is challenging. Thus, the pursuit of complementary approaches to quantify growth kinetics becomes mandatory in order to better understand fungal cell growth. Furthermore, it is well-known that filamentous fungi, including Aspergillus spp., have distinct modes of growth and differentiation under sub-aerial conditions on solid media or submerged cultures. Here, we detail a quantitative microscopic method for analyzing growth kinetics of the model fungus Aspergillus nidulans, using live imaging in both submerged cultures and solid media.

We carried out an experiment with forty students from fifth semester Electronics and Communication Engineering department. The students used a FOSS tool and gave a test based on designing of various antennas with desired radiation patterns by selecting different parameters before and after using the tool. The scores of the two tests show that there was an increase in the marks obtained by students in the test after using the tool. Thus the use of FOSS tool helped students perform better in the test.

Previous studies predict a talent's next job title solely based on her past experience in the resume, which can lead to errors if the resume contains fake information. With the popularity of open-source software, we argue that the next job title can be predicted based on a candidate's past expertise in the open-source community. On the other hand, the career path can also affect the development of a talent's expertise.

Design/methodology/approach - A quantitative study was designed using choose tasks that were carried out via the email discourse on the developers' email fora in five FLOSS projects. Choice process episodes were selected as the unit of analysis and were coded for the task trigger and topic. The impact of these factors on participation (i.e. the numbers of participants and messages) was assessed by regression. Findings - The results reveal differences in participation related to different task triggers and task topics. Further, the results suggest the mediating role of the number of participants in the relationships between task characteristics and the number of messages. The authors also speculate that project type serves as a boundary condition restricting the impacts of task characteristics on the number of participants and propose this relationship for future research. Research limitations/implications - Empirical support was provided to the important effects of different task characteristics on individual participation behaviors in FLOSS development tasks. Practical implications - The findings can help FLOSS participants understand participation patterns in different tasks and choose the types of tasks to attend to. Originality/value - This research explores the impact of task characteristics on participation in FLOSS development at the task level, while prior research on participation in FLOSS development has focused mainly on factors at the individual and/or project levels.}, DOI = {10.1108/INTR-03-2020-0112}, EarlyAccessDate = {FEB 2021}, ISSN = {1066-2243}, ResearcherID-Numbers = {Eseryel, Yeliz/AAE-3379-2021 Crowston, Kevin/C-6068-2008 }, ORCID-Numbers = {Crowston, Kevin/0000-0003-1996-3600 Eseryel, Ugur Yeliz/0000-0003-2734-4498}, Unique-ID = {WOS:000620017000001}, } @incollection{ WOS:000417973200039, Author = {MacKellar, Bonnie K. and Sabin, Mihaela and Tucker, Allen B.}, Book-Group-Author = {IRMA}, Title = {Bridging the Academia-Industry Gap in Software Engineering: A Client-Oriented Open Source Software Projects Course}, Booktitle = {STEM EDUCATION: CONCEPTS, METHODOLOGIES, TOOLS, AND APPLICATIONS}, Year = {2015}, Pages = {710-733}, Abstract = {Too often, computer science programs offer a software engineering course that emphasizes concepts, principles, and practical techniques, but fails to engage students in real-world software experiences.

OSS is a complicated social process to understand. OSS is a multi-faceted phenomenon including code, a licensing structure, a community, development best practices, a method of diffusion. However, the current OSS collaborative researches place too much emphasis on collaborative behaviors, but ignore the study on collaborative process. By using the social network theory to abstract collaborative network topology, this paper proposes a method for constructing social network model, which considers both the contact relationship and level of collaboration between collaborators. Based on the definition of three types of contact behavior, this paper presents an approach to measuring the contact relationship intensity. Based on introducing and improving TF-IDF (term frequency-inverse document frequency), this paper presents the methods for calculating tag weights and work similarity between collaborators.

The quantitation problem is mathematically formulated as a separable nonlinear least-squares fitting problem, which is numerically solved using a modified variable-projection procedure. A macromolecular baseline is incorporated into the fit via nonparametric modelling, efficiently implemented using penalized splines. Unwanted components such as residual water are removed with a maximum-phase FIR filter. Constraints on the phases, dampings and frequencies of the metabolites can be imposed. AQSES has been tested on simulated MR spectra with several types of disturbance and on short echo time in vivo proton MR spectra. Results show that AQSES is robust, easy to use and very flexible.

The Madagascar, based on Python, is usually supposed to be better in the development of processing technologies due to its capabilities of multidimensional data analysis and reproducibility. However, this open-source software has not been widely used so far for field data processing because of complicated interfaces and data structure system. To verify the effectiveness of the Madagascar software on field data, we applied it to a typical seismic data processing flow including data loading, geometry build-up, F-K filter, predictive deconvolution, velocity analysis, normal moveout correction, stack, and migration. The field data for the test were acquired in Gunsan Basin, Yellow Sea using a streamer consisting of 480 channels and 4 arrays of air-guns. The results at all processing step are compared with those processed with Landmark's ProMAX (SeisSpace R5000) which is a commercial processing software. Madagascar shows relatively high efficiencies in data IO and management as well as reproducibility. Additionally, it shows quick and exact calculations in some automated procedures such as stacking velocity analysis. There were no remarkable differences in the results after applying the signal enhancement flows of both software. For the deeper part of the substructure image, however, the commercial software shows better results than the open-source software. This is simply because the commercial software has various flows for de-multiple and provides interactive processing environments for delicate processing works compared to Madagascar. Considering that many researchers around the world are developing various data processing algorithms for Madagascar, we can expect that the open-source software such as Madagascar can be widely used for commercial-level processing with the strength of expandability, cost effectiveness and reproducibility.}, DOI = {10.7582/GGE.2018.21.3.171}, ISSN = {1229-1064}, EISSN = {2384-051X}, Unique-ID = {WOS:000447723200004}, } @incollection{ WOS:000442905400100, Author = {MacKellar, Bonnie K. and Sabin, Mihaela and Tucker, Allen B.}, Book-Group-Author = {Informat Resources Management Assoc}, Title = {Bridging the Academia-Industry Gap in Software Engineering: A Client-Oriented Open Source Software Projects Course}, Booktitle = {OPEN SOURCE TECHNOLOGY: CONCEPTS, METHODOLOGIES, TOOLS, AND APPLICATIONS}, Year = {2015}, Pages = {1927-1950}, Abstract = {Too often, computer science programs offer a software engineering course that emphasizes concepts, principles, and practical techniques, but fails to engage students in real-world software experiences.

In order to identify effective approaches to overcome collaboration barriers, we systematically studied the case of the Brazilian Public Software portal project, a 30-month government-academia collaboration that, using Free/Libre/Open Source Software practices and agile methods for project management, developed an unprecedented platform in the context of the Brazilian government.

The developed software environment follows to a large extent the UNIX design philosophy and is heavily based on open-source software technologies that are used to solve specific tasks within the overall system to achieve high productivity in using the software for ambitious high-throughput experimentation programs. It is shown that the orchestration of the system significantly benefits from clear and standardized interface design based on hteML, the high-throughput experimentation markup language, an XML language for the description of high-throughput experimentation data and processes.

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors' engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors' attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.}, DOI = {10.1109/TSE.2023.3242415}, ISSN = {0098-5589}, EISSN = {1939-3520}, ResearcherID-Numbers = {Zhang, Li/AAA-9787-2020 }, ORCID-Numbers = {Zhang, Li/0000-0002-2258-5893 Tan, Xin/0000-0003-1099-3336 Zhou, Minghui/0000-0001-6324-3964}, Unique-ID = {WOS:000991628700005}, } @inproceedings{ WOS:000449166500002, Author = {Wen, Melissa and Meirelles, Paulo and Siqueira, Rodrigo and Kon, Fabio}, Editor = {Stamelos, I and GonzalezBarahona, JM and Varlamis, I and Anagnostopoulos, D}, Title = {FLOSS Project Management in Government-Academia Collaboration}, Booktitle = {OPEN SOURCE SYSTEMS: ENTERPRISE SOFTWARE AND SOLUTIONS, OSS 2018}, Series = {IFIP Advances in Information and Communication Technology}, Year = {2018}, Volume = {525}, Pages = {15-25}, Note = {14th IFIP WG 2.13 International Conference on Open Source Systems (OSS), Athens, GREECE, JUN 08-10, 2018}, Organization = {Harokopio Univ; IFIP WG 2 13}, Abstract = {Government and academia can collaborate on bringing innovation and filling design-reality gaps in e-government projects.

However, the incomplete understanding of the phenomenon has continued to prompt researchers to investigate factors that could increase the use and popularity of open source software (ass). While a key antecedent for OSS use highlighted in the previous literature is the software quality, we propose that effective online user support is also necessary to increase its popularity. As an understudied area, this paper seeks to understand the role of online user support networks in facilitating OSS use. Based on the network embeddedness theory, it suggests that properties of the user support network i.e., variation in structural and junctional embeddedness, measured as the in-degree and betweenness centralizations respectively, would affect OSS popularity in terms of the number of active users and downloads of the software. Testing on a sample of 176 OSS projects from Sourceforge.net, we showed that a negative quadratic relationship exists between the variation in structural embeddedness of the OSS user support network and the software popularity. Further, as hypothesized, the variation in junctional embeddedness was found to positively impact the OSS popularity. Theoretical and practical implications of the study are discussed.

BCIs are communication systems that enable users to send commands to computers solely by means of brain activity. BCIs are gaining interest among the virtual reality (VR) community since they have appeared as promising interaction devices for virtual environments (VEs). The key features of the platform are (1) high modularity, (2) embedded tools for visualization and feedback based on VR and 3D displays, (3) BCI design made available to non-programmers thanks to visual programming, and (4) various tools offered to the different types of users. The platform features are illustrated in this paper with two entertaining VR applications based on a BCI. In the first one, users can move a virtual ball by imagining hand movements, while in the second one, they can control a virtual spaceship using real or imagined foot movements. Online experiments with these applications together with the evaluation of the platform computational performances showed its suitability for the design of VR applications controlled with a BCI.

To further the efforts toward a more effective and quicker response to bugs, we must understand the factors that affect the time it takes to fix one. We apply a custom traversal algorithm to commits made for open source repositories to determine when ``simple stupid bugs{''} were first introduced to projects and explore the factors that drive the time it takes to fix them. Using the commit history from the main development branch, we are able to identify the commit that first introduced 13 different types of simple stupid bugs in 617 of the top Java projects on GitHub.

We find that bugs are fixed quicker if they are introduced and resolved by the same developer. Further, we discuss how the day of the week and time of day a buggy code was written and fixed affects its resolution time.

Results from early clinical trials indicated that there was a lack of confidence in image interpretation. Such confidence can only be gained through rigorous imaging tests using complex, heterogeneous but known media. The objective of this study is to build a virtual breast QUE simulation platform in the public domain that can be used not only for innovative QUE research but also for rigorous imaging tests. Methods: The main thrust of this work is to streamline biomedical ultrasound simulations by leveraging existing open source software packages including Field II (ultrasound simulator), VTK (geometrical visualization and processing), FEBio {[}finite element (FE) analysis], and Tetgen (mesh generator). However, integration of these open source packages is nontrivial and requires interdisciplinary knowledge. In the first step, a virtual breast model containing complex anatomical geometries was created through a novel combination of image-based landmark structures and randomly distributed (small) structures. Image-based landmark structures were based on data from the NIH Visible Human Project. Subsequently, an unstructured FE-mesh was created by Tetgen. In the second step, randomly positioned point scatterers were placed within the meshed breast model through an octree-based algorithm to make a virtual breast ultrasound phantom. In the third step, an ultrasound simulator (Field II) was used to interrogate the virtual breast phantom to obtain simulated ultrasound echo data. Of note, tissue deformation generated using a FE-simulator (FEBio) was the basis of deforming the original virtual breast phantom in order to obtain the postdeformation breast phantom for subsequent ultrasound simulations. Using the procedures described above, a full cycle of QUE simulations involving complex and highly heterogeneous virtual breast phantoms can be accomplished for the first time. Results: Representative examples were used to demonstrate capabilities of this virtual simulation platform. In the first set of three ultrasound simulation examples, three heterogeneous volumes of interest were selected from a virtual breast ultrasound phantom to perform sophisticated ultrasound simulations. These resultant B-mode images realistically represented the underlying complex but known media. In the second set of three QUE examples, advanced applications in QUE were simulated. The first QUE example was to show breast tumors with complex shapes and/or compositions. The resultant strain images showed complex patterns that were normally seen in freehand clinical ultrasound data. The second and third QUE examples demonstrated (deformation-dependent) nonlinear strain imaging and time-dependent strain imaging, respectively. Conclusions: The proposed virtual QUE platform was implemented and successfully tested in this study. Through show-case examples, the proposed work has demonstrated its capabilities of creating sophisticated QUE data in a way that cannot be done through the manufacture of physical tissue-mimicking phantoms and other software. This open software architecture will soon be made available in the public domain and can be readily adapted to meet specific needs of different research groups to drive innovations in QUE.

A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing.

Unfortunately this goal has not been achieved mainly due to a lack of both tools and data management, as data must be gathered from different sources and in different formats. Compounding this problem is the fact that in some regions different water agencies are in charge of water supply as is the case in the Basin of Mexico, in which Mexico City and its Metropolitan Zone are located. The inhabitants of the Basin of Mexico, which comprises five different political entities and in which different agencies are in charge of water supply rely on the Basin's aquifer system as its main water supply source. However, a regional hydrogeological database in this area does not exist which is why the use of both a Relational Database Management System (RDMBS) and a Geographic Information System (GIS) is proposed in order to improve regional data management in the study area. Data stored in this new database, the Basin of Mexico Hydrogeological Database (BMHDB) comprise data on climatological, borehole and run-off variables, readily providing information for the development of hydrogeological models. A simple example is used to show how geostatistical analysis can be done using the data directly from the BMHDB. The structure of the BMHDB allows easy maintenance and updating, representing a valuable tool for the development of regional studies. (c) 2008 Elsevier Ltd.

Design/methodology/approach - Two studies were carried out. In Study 1, a content analysis classifying OSS-related questions posted during December 2005-December 2012 in Yahoo! Answers was employed to investigate the general public's information needs regarding OSS. In Study 2, an online survey was conducted with OSS answerers in Yahoo! Answers in order to examine what motivates them to share and continue to share their knowledge of OSS in social Q\&A. In total, 1,463 invitations were sent out via Yahoo! Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q\&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q\&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q\&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q\&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).}, DOI = {10.1108/OIR-06-2014-0139}, ISSN = {1468-4527}, EISSN = {1468-4535}, ResearcherID-Numbers = {Yi, Kwan/H-7902-2012}, Unique-ID = {WOS:000350588600008}, } @inproceedings{ WOS:000303073400014, Author = {Crowston, Kevin}, Editor = {Chiasson, M and Henfridsson, O and Karsten, H and DeGross, JI}, Title = {Lessons from Volunteering and Free/Libre Open Source Software Development for the Future of Work}, Booktitle = {RESEARCHING THE FUTURE IN INFORMATION SYSTEMS}, Series = {IFIP Advances in Information and Communication Technology}, Year = {2011}, Volume = {356}, Pages = {215-229}, Note = {IFIP WG 8 2 Working Conference, Abo Akad Univ, Turku, FINLAND, JUN 06-08, 2011}, Organization = {IFIP, WG; Copenhagen Business Sch; Turku Ctr Comp Sci; Turku Sci Pk; Turku 2011 Cultural Capital Europe; Stiftelsen Abo Akad; Tieteellisten Seurain Valtuuskunta}, Abstract = {In this paper, we review research on voluntary organizations to identify key features of and problems in volunteer work and organizations.

GaugeCam Remote Image Manager-Educational 2 (GRIME2) is a mature, open-source commercial friendly software application that automatically detects and measures water level in laboratory and field settings. The software relies on a dedicated target background for water line detection and image calibration. The system detects the change in pixel gray scale values associated with the intersection of the water level at the target surface. Fiducials on the target background are used to precisely create a pixel to real world coordinate transfer matrix and to correct for camera movement. The presented software package implements the algorithms and automates the water level measurement process, annotation of images with result overlays, creation of animations, and output of results to files that can be further analyzed in a spreadsheet or with R or Python. These GRIME2 features are illustrated using imagery from a coastal marsh field site.

The model has an outer layer exchanging radiation and heat with the environment and a stack of layers beyond modifying the thermal behavior. The orientation of the layer is defined by the normal vector of the surface. The innermost layer is at a constant or variable temperature called core temperature. All the layers have heat capacity and thermal conductivity. The outer layers properties are color (visible), emissivity (IR), coefficients of free and forced convection, and a factor for latent heat. The environmental parameters are air temperature, wind speed, relative humidity, irradiation of the sun, and thermal radiation of the sky and ground. The properties of the model (7 parameters) are fitted to minimize the difference between the prediction and a time series of measured temperatures. The size of the time series is one or more days with 288 values per day (5 minute resolution). The model is useable for very different objects like backgrounds (meadow, forest, rocks, sand, or bricks) or parts of objects like vehicles. The STANDCAM is a decoy of a vehicle and is used to constitute a thermal signature and is not classified. The STANDCAM has a complex CAD-Model with thousands of triangular facets that had to be simplified for the thermal simulation. The CAD model was available through WTD 52, an agency of the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw). Groups of elements of the model facing in the same direction and behaving similarly were cut out and grouped in distinct objects. The calculation of the temperature of the objects is based on measured environmental data and the model parameters are fitted on measured radiation temperatures of the objects and backgrounds. For the visualization the object is surrounded by a world texture. For the radiation temperature of the environment and the ground under the object measured air and meadow temperatures were used. The temperature is coded as a color from a palette (here we use a grey palette) and is updated regularly throughout the calculation of the scene for the selected view and is stored as a texture bitmap. The animation of the temperature textures is directly performed by BLENDER.

Our laboratory exploits PCR techniques and Next Generation Sequencing (NGS) methods to perform high-throughput integration site monitoring in different clinical trials and scientific projects. Because of the huge amount of samples that we process every year, which result in hundreds of millions of sequencing reads, we need to standardize data management and tracking systems, building up a scalable and flexible structure with web-based interfaces, which are usually called Laboratory Information Management System (LIMS). Methods: We started collecting end-users' requirements, composed of desired functionalities of the system and Graphical User Interfaces (GUI), and then we evaluated available tools that could address our requirements, spanning from pure LIMS to Content Management Systems (CMS) up to enterprise information systems. Our analysis identified ADempiere ERP, an open source Enterprise Resource Planning written in Java J2EE, as the best software that also natively implements some highly desirable technological advances, such as the high usability and modularity that grants high use-case flexibility and software scalability for custom solutions. Results: We extended and customized ADempiere ERP to fulfil LIMS requirements and we developed adLIMS. It has been validated by our end-users verifying functionalities and GUIs through test cases for PCRs samples and pre-sequencing data and it is currently in use in our laboratories. adLIMS implements authorization and authentication policies, allowing multiple users management and roles definition that enables specific permissions, operations and data views to each user. For example, adLIMS allows creating sample sheets from stored data using available exporting operations. This simplicity and process standardization may avoid manual errors and information backtracking, features that are not granted using track recording on files or spreadsheets. Conclusions: adLIMS aims to combine sample tracking and data reporting features with higher accessibility and usability of GUIs, thus allowing time to be saved on doing repetitive laboratory tasks, and reducing errors with respect to manual data collection methods. Moreover, adLIMS implements automated data entry, exploiting sample data multiplexing and parallel/transactional processing. adLIMS is natively extensible to cope with laboratory automation through platform-dependent API interfaces, and could be extended to genomic facilities due to the ERP functionalities.}, DOI = {10.1186/1471-2105-16-S9-S5}, Article-Number = {S5}, ISSN = {1471-2105}, ResearcherID-Numbers = {Calabria, Andrea/AAA-3349-2019 Montini, Eugenio/L-1152-2016 Spinozzi, Giulio/IAQ-9915-2023 }, ORCID-Numbers = {Montini, Eugenio/0000-0003-1771-6067 Spinozzi, Giulio/0000-0002-4220-2474 Calabria, Andrea/0000-0003-3515-3384}, Unique-ID = {WOS:000367875300005}, } @article{ WOS:000420591000004, Author = {Celik, Sonmez and Bugan, Onur}, Title = {Open Journal Systems (OJS): a system of open source software for journal management and publishing}, Journal = {YUKSEKOGRETIM DERGISI}, Year = {2013}, Volume = {3}, Number = {1}, Pages = {12-21}, Month = {APR}, Abstract = {Academic journals help timely publish of scientific research results, share of information, help research results to be permanent and through these contribute the development of science.

The software integrates a number of modular functions through a custom graphical user interface (GUI) and provides extensive control over a wide range of inexpensive IEEE 1394 Firewire cameras.

The bug reports and the responses are jointly modeled, to find latent topics that will best predict the response variables for future unlabeled bug reports.

Our experimental results in installations of OSS packages including the one requiring the integration of four packages by generated manuals verify the effectiveness of our method.}, DOI = {10.1109/SITIS.2008.62}, ISBN = {978-0-7695-3493-0}, Unique-ID = {WOS:000263157200075}, } @inproceedings{ WOS:001281987600253, Author = {Paton, Chris and Amarakoon, Pamod and Braa, Jorn and Kobayashi, Shinji and Marcelo, Alvin and Kane, Tom and Fraser, Hamish and Hannan, Terry}, Editor = {Bichel-Findlay, J and Otero, P and Scott, P and Huesing, E}, Title = {Open Source Software in Healthcare: International Case Series from the IMIA Open Source Working Group}, Booktitle = {MEDINFO 2023 - THE FUTURE IS ACCESSIBLE}, Series = {Studies in Health Technology and Informatics}, Year = {2024}, Volume = {310}, Pages = {1266-1270}, Note = {19th World Congress on Medical and Health Informatics (MEDINFO), Sydney, AUSTRALIA, JUL 08-12, 2023}, Abstract = {In this case series, we demonstrate how open-source software has been widely adopted as the primary health information system in many low- and middle-income countries, and for government-developed applications in high-income settings.

Within this literature, polycentric urban regions are commonly defined as territories that have multiple, proximately located (sub)centers and are characterized by balanced urban development. However, analytical-operational frameworks to identify and classify PURs are often ad hoc efforts to answer a specific research question and underlying work is often shelved rather than shared and/or made accessible. As a result, challenges associated with generalizability, reproducibility, and replicability clearly loom large in the urban polycentricity literature. Against this backdrop, this article describes the discrepancy between a rich debate on polycentricity and the paucity of tools enabling the disambiguation and reproducibility of results claimed by various authors around this polysemic concept. We present an online and open tool-PURban-that brings together the major analytical-operational frameworks and data sets in urban polycentricity research and allows parametrizing key operational choices. To illustrate the tool, we demonstrate how it facilitates the identification, mapping and analysis of degrees of morphological polycentricity in European urban systems. We conclude by reflecting on how this tool can act as a catalyst for future research on urban polycentricity.}, DOI = {10.1111/gean.12313}, EarlyAccessDate = {NOV 2021}, ISSN = {0016-7363}, EISSN = {1538-4632}, ResearcherID-Numbers = {van migerode, céline/KYP-4469-2024 Derudder, Ben/ABH-5648-2020 }, ORCID-Numbers = {Derudder, Ben/0000-0001-6195-8544 Van Migerode, Celine/0000-0002-4023-7665}, Unique-ID = {WOS:000716192900001}, } @article{ WOS:000837495900001, Author = {Patrick, Haley M. and Kildea, John}, Title = {Technical Note: rtdsm-An open-source software for radiotherapy dose-surface map generation and analysis}, Journal = {MEDICAL PHYSICS}, Year = {2022}, Volume = {49}, Number = {11}, Pages = {7327-7335}, Month = {NOV}, Abstract = {Background Dose-outcome studies in radiation oncology have historically excluded spatial information due to dose-volume histograms being the most dominant source of dosimetric information. In recent years, dose-surface maps (DSMs) have become increasingly popular for characterization of spatial dose distributions and identification of radiosensitive subregions for hollow organs. However, methodological variations and lack of open-source, publicly offered code-sharing between research groups have limited reproducibility and wider adoption. Purpose This paper presents rtdsm, an open-source software for DSM calculation with the intent to improve the reproducibility of and the access to DSM-based research in medical physics and radiation oncology. Methods A literature review was conducted to identify essential functionalities and prevailing calculation approaches to guide development. The described software has been designed to calculate DSMs from DICOM data with a high degree of user customizability and to facilitate DSM feature analysis. Core functionalities include DSM calculation, equivalent dose conversions, common DSM feature extraction, and simple DSM accumulation. Results A number of use cases were used to qualitatively and quantitatively demonstrate the use and usefulness of rtdsm. Specifically, two DSM slicing methods, planar and noncoplanar, were implemented and tested, and the effects of method choice on output DSMs were demonstrated. An example comparison of DSMs from two different treatments was used to highlight the use cases of various built-in analysis functions for equivalent dose conversion and DSM feature extraction. Conclusions We developed and implemented rtdsm as a standalone software that provides all essential functionalities required to perform a DSM-based study.

They provide critical information and enhance environmental integrity in planning and development of GHG mitigation policy. The characteristics of a high quality inventory are that it follows good practice according to the IPCC guidelines. The key components of good practice are that the inventory is transparent to others, has accurate and complete emissions estimates for all gases, sources and sinks; has consistent application of methods across time; and is comparable to inventories from other countries {[}1]. While developed countries struggle with implementation of good practice, most can produce reasonably high quality inventories {[}2]. However, the task is more challenging in low lying pacific island countries. Some of the specific challenges include: lack of clarity on roles and responsibilities of agencies in preparing inventories; small teams with limited resources; difficulty in retaining expertise; incomplete or non-existent activity data; inconsistent data between inventories; absence of an archiving system for previous inventories; no QA/QC plan {[}3]. As part of the UN-REDD Programme project on ``Strengthening Regional Support to National Forest Monitoring Systems for REDD+ in the Pacific{''} a Regional Monitoring System has been developed to support low lying pacific island countries (Republic of Palau, Tuvalu, Cook Islands, Tonga, Republic of Kiribati, and Federated States of Micronesia).

Clients may struggle to select the best OSS-LMS package from a wide range of options, leading to a complex multi-criteria group decision -making (MCGDM) problem. This evaluates OSS-LMS packages based on several criteria like us-ability, functionality, e-learning standards, reliability, activity tracking, course development, assess-ment, backup and recovery, error reporting, efficiency, operating system compatibility, computer -managed instruction, authentication, authorization, troubleshooting, maintenance, upgrading, and scalability. Handling uncertain data is a vital aspect of OSS-LMS package evaluation. To tackle MCGDM issues, this study presents a consensus weighted sum product (c-WASPAS) method which is applied to an educational OSS-LMS package selection problem to evaluate four OSS-LMS pack-ages, namely ATutor, eFront, Moodle, and Sakai. The findings indicate that the priority order of alternatives is Moodle > Sakai > eFront > ATutor and, therefore, MOODLE is the best OSS-LMS package for the case study. A sensitivity analysis of criteria weights is also conducted, as well as a comparative study, to demonstrate the effectiveness of the proposed method. It is essential to note that proper OSS-LMS package evaluation is crucial to avoid negative impacts on organizational per-formance. By addressing MCGDM issues and dealing with uncertain information, the c-WASPAS method presented in this study can assist clients in selecting the most appropriate OSS-LMS pack-age from multiple alternatives.

Design/methodology/approach - Through an empirical, interpretive case study and a literature review utilising the metaphor of text in the analysis, this paper provides a refined conceptualisation of user participation in OSS development. Findings - The paper reveals that different kinds of meanings have been attached to users and to their participation. User participation is both direct and indirect in the OSS development context. Some user groups actively take part in OSS development, while others are merely represented in it. Different kinds of intermediaries ``representing the users{''} are identified. Research limitations/implications - The research is based on one case study on a small but active OSS project with an interest in users. Other kinds of OSS projects should be analysed. The analysis was focused on a discussion forum, but users can take part in OSS development by other means as well. Paths for future work should include the gathering of more varied empirical data. Practical implications - The findings indicate that users can provide feedback to the development through discussion forums in the distributed environment, but there is a need to support the users in doing so and the developers in analysing the data.

This would help software developers to judiciously allocate the resources used for testing and maintenance. Software metrics can be used for constructing various classification models which can be used for timely identification of change prone classes. Search based algorithms which form a subset of machine learning algorithms can be utilized for constructing prediction models to identify change prone classes of software. Search based algorithms use a fitness function to find the best optimal solution among all the possible solutions. In this work, we analyze the effectiveness of hybridized search based algorithms for change prediction. In other words, the aim of this work is to find whether search based algorithms are capable for accurate model construction to predict change prone classes. We have also constructed models using machine learning techniques and compared the performance of these models with the models constructed using Search Based Algorithms. The validation is carried out on two open source Apache projects, Rave and Commons Math. The results prove the effectiveness of hybridized search based algorithms in predicting change prone classes of software. Thus, they can be utilized by the software developers to produce an efficient and better developed software. (C) 2016 Elsevier Ltd.

Thanks to this attractive outlook, the field has thrived and in the past few years has seen an especially significant growth, mainly due to the emergence of novel methods based on deep neural networks. This growth is also apparent in the development of novel de novo drug design methods with many new generative algorithms now available. However, widespread adoption of new generative techniques in the fields like medicinal chemistry or chemical biology is still lagging behind the most recent developments. Upon taking a closer look, this fact is not surprising since in order to successfully integrate the most recent de novo drug design methods in existing processes and pipelines, a close collaboration between diverse groups of experimental and theoretical scientists needs to be established. Therefore, to accelerate the adoption of both modern and traditional de novo molecular generators, we developed Generator User Interface (GenUI), a software platform that makes it possible to integrate molecular generators within a feature-rich graphical user interface that is easy to use by experts of diverse backgrounds. GenUI is implemented as a web service and its interfaces offer access to cheminformatics tools for data preprocessing, model building, molecule generation, and interactive chemical space visualization. Moreover, the platform is easy to extend with customizable frontend React.js components and backend Python extensions. GenUI is open source and a recently developed de novo molecular generator, DrugEx, was integrated as a proof of principle. In this work, we present the architecture and implementation details of GenUI and discuss how it can facilitate collaboration in the disparate communities interested in de novo molecular generation and computer-aided drug discovery.}, DOI = {10.1186/s13321-021-00550-y}, Article-Number = {73}, ISSN = {1758-2946}, ResearcherID-Numbers = {刘, 许晗/IAP-7614-2023 Svozil, Daniel/D-4407-2009 van Westen, Gerard/D-7432-2011 }, ORCID-Numbers = {Svozil, Daniel/0000-0003-2577-5163 Sicho, Martin/0000-0002-8771-1731 van Westen, Gerard/0000-0003-0717-1817 Liu, Xuhan/0000-0003-2368-4655}, Unique-ID = {WOS:000699031900001}, } @inproceedings{ WOS:000368495600009, Author = {Gamalielsson, Jonas and Jakobsson, Fredrik and Lundell, Bjorn and Feist, Jonas and Gustavsson, Tomas and Landqvist, Fredric}, Editor = {Damiani, E and Frati, F and Riehle, D and Wasserman, AI}, Title = {On the Availability and Effectiveness of Open Source Software for Digital Signing of PDF Documents}, Booktitle = {OPEN SOURCE SYSTEMS: ADOPTION AND IMPACT}, Series = {IFIP Advances in Information and Communication Technology}, Year = {2015}, Volume = {451}, Pages = {71-80}, Note = {11th IFIP WG 2.13 Annual International Conference on Open Source Systems (OSS), Florence, ITALY, MAY 16-17, 2015}, Organization = {IFIP WG 2 13; Google}, Abstract = {Digital signatures are important in order to ensure the integrity and authenticity of information communicated over the Internet involving different stakeholders within and beyond the borders of different nations.

OSS is mainly developed by developers, volunteers, and users all over the world, but its reliability has been widely questioned. When OSS faults are detected, volunteers or users send them to developers by email or network. After the developer confirms the fault, it will be randomly assigned to the debugger who may be a developer, a volunteer, or a user. These open source community contributors also have the phenomenon of learning when removing faults. When the detected faults are removed, the number of introduced faults decreases gradually. Therefore, this study proposes a software reliability model with the decreasing trend of fault introduction in the process of OSS development and testing. The validity of the proposed model and the accuracy of estimating residual faults are verified by experiments. The proposed model can be used to evaluate the reliability and predict the remaining faults in the actual OSS development and testing process.}, DOI = {10.1371/journal.pone.0267171}, Article-Number = {e0267171}, ISSN = {1932-6203}, ResearcherID-Numbers = {yang, jianying/N-4615-2013 }, ORCID-Numbers = {Wang, Jinyong/0000-0003-4167-1313}, Unique-ID = {WOS:000793332400007}, } @incollection{ WOS:000413544400011, Author = {Pina, Pedro}, Book-Author = {Gordon, S}, Title = {Free and Open Source Software Movements as Agents of an Alternative Use of Copyright Law}, Booktitle = {ONLINE COMMUNITIES AS AGENTS OF CHANGE AND SOCIAL MOVEMENTS}, Series = {Advances in Social Networking and Online Communities}, Year = {2017}, Pages = {253-270}, Abstract = {Digital technology produced a move from a performative model to a player-as producer paradigm since it has potentiated user-generated transformative uses of intellectual works.

We are dependent on software controlled by global technology giants. The dependence on commonly used services and platforms provided by Microsoft, Google or Amazon must be removed to achieve digital sovereignty. Open-source software has been readily available for a long time, but studies looking into excluding all proprietary software from working life are scarce. This paper investigates the feasibility of replacing proprietary software as a step towards digital sovereignty. The ability to self-host services is key to ensuring independence, and the ability to verify software code is key to ensuring integrity. Therefore open-source code and transparency are transient properties for sovereign software. We present problems by mapping the problematic software used by teachers, researchers and student assistants at Arcada UAS with a varied set of requirements on the digital tools of their daily lives. We research alternatives and deploy a suite of software compatible with EU policies on digital sovereignty. We rely on many services offered by tech giants in our professional lives. There are several open-source software suites that can be self-hosted and that have permissive licenses for business use. Extensive technical knowledge is required for the deployment of software. Most daily tasks can be accomplished by using sovereign software, although not all needs of the test group were met. Companies can deploy sovereign software for most daily tasks, reducing dependency on tech giants. However, software adoption was low. Arcadas IT-support does not host, enforce or endorse the usage of sovereign software. Public code repositories enable independent code verification, in contrast to proprietary software. Some software cannot be easily replaced, and digital habits are hard to change.}, DOI = {10.1007/978-3-031-61891-8\_10}, ISSN = {2367-3370}, EISSN = {2367-3389}, ISBN = {978-3-031-61890-1; 978-3-031-61891-8}, ResearcherID-Numbers = {Stocchetti, Matteo/HSD-1477-2023 }, ORCID-Numbers = {Stocchetti, Matteo/0000-0002-6725-7842}, Unique-ID = {WOS:001289487100010}, } @article{ WOS:000497088000001, Author = {Hobbs, S.

Can such an instrument be developed and tested to assist with automated detection of materials, possibly from space? We tested two spectrometer designs inside a two unit (2U) cubesat frame against a series of materials exhibiting phenomenology in the visible/near infrared (Vis/NIR) portion of the spectrum and vegetation groups. This was conducted in order to determine whether open source designs were capable of discriminating against similar materials, such as types of vegetation or types of iron-rich minerals. A spectral pipeline was created using open source programming software that was capable of converting raw sensor data into spectra, comparing samples of interest against a spectral library and returning an identification result with a confidence interval.

The skeletal muscle chemoelectromechanical model is based on a bottom-up approach modeling the entire excitation-contraction pathway by strongly coupling a detailed biophysical model of a half-sarcomere to the propagation of action potentials along skeletal muscle fibers and linking cellular parameters to a transversely isotropic continuum-mechanical constitutive equation describing the overall mechanical behavior of skeletal muscle tissue. Since the multiscale model exhibits separable time scales, a special emphasis is placed on employing computationally efficient staggered solution schemes. Further, the implementation builds on the open-source software library OpenCMISS and uses state-of-the-art parallelization techniques taking advantage of the unique anatomical fiber architecture of skeletal muscles. OpenCMISS utilizes standardized data structures for geometrical aspects (FieldML) and cellular models (CellML). Both standards are designed to allow for a maximum flexibility, reproducibility, and extensibility.

Central to the automation of these systems is the early detection of named entities, a task that is foundational yet fraught with challenges due to the need for domain-specific expert annotations amid a backdrop of specialized terminologies, making the process both costly and complex. In response to this challenge, our paper presents an innovative named entity recognition (NER) framework (https://github. com/NeuralSentinel/DistALANER) tailored for the open-source software domain. Our method stands out by employing a distantly supervised, two-step annotation process that cleverly exploits language heuristics, bespoke lookup tables, external knowledge bases, and an active learning model. This multifaceted strategy not only elevates model performance but also addresses the critical hurdles of high costs and the dearth of expert annotators. A notable achievement of our approach is its capability to enable pre-large language models (pre-LLMs) to significantly outperform specially designed generic/domain specific LLMs for NER tasks.

Glare has functions including generating speckle patterns, rendering deformed images, assessing pattern quality, and presenting pattern recommendations: Glare can generate ellipse, polygon, and Gaussian speckle patterns; can render deformed images with underlying deformation fields of translation, stretch/compression, rotation, sinusoidal deformation, Gaussian deformation, and Portevin-Le Chatelier band deformation; can calculate key pattern quality assessment parameters such as speckle coverage, speckle size, systematic error, and random error; can produce optimized speckle pattern in form of vector image. The software realizes real-time deformed image rendering with the aid of fast initial value estimation algorithm for backward mapping and pattern pre-rendering technique, and improves the computational efficiency of sum of square of subset intensity gradients by integral image method.

We exemplify the use of the model by applying it to the Apache Tomcat web portal and we apply the model to 47 web sites of well-known OSS products to highlight the current deficiencies that characterize these web portals.}, ISSN = {1865-1348}, ISBN = {978-3-642-28081-8}, ResearcherID-Numbers = {TOSI, DAVIDE/AAI-1310-2020 Lavazza, Luigi/AAF-5323-2020 Taibi, Davide/E-4935-2015 }, ORCID-Numbers = {TOSI, DAVIDE/0000-0003-3815-2512 Morasca, Sandro/0000-0003-4598-7024 Taibi, Davide/0000-0002-3210-3990 Lavazza, Luigi/0000-0002-5226-4337}, Unique-ID = {WOS:000309893000011}, } @article{ WOS:000324356200004, Author = {De Noni, Ivan and Ganzaroli, Andrea and Orsi, Luigi}, Title = {The evolution of OSS governance: a dimensional comparative analysis}, Journal = {SCANDINAVIAN JOURNAL OF MANAGEMENT}, Year = {2013}, Volume = {29}, Number = {3}, Pages = {247-263}, Month = {SEP}, Abstract = {The competiveness of Open Source Software (OSS) communities depends on the quantity and combination of resources and competencies attracted to and retained at each stage of the innovation process.

Despite their importance, we still know little about how governance mechanisms are combined in 055 communities. This paper contributes to filling part of that gap. The study is based on an explorative factor analysis conducted on a database of 40 case studies of OSS projects hosted in Freshmeat. The results show OSS governance is configurational, and highlights four likely configurations of governance. (C) 2012 Elsevier Ltd.

In Indonesia alone, 25\% of South East Asia's mangroves are at a risk. The continued decline in mangrove forest induced by anthropogenic activity has made all the stakeholders who have the concern at the mangrove forest preservation worried, including the government. There were several programs have been performed by the government to preserve the mangrove forest. One of the programs was ``Mangrove Rehabilitation Program in three districts: Ciamis, Indramayu, and Subang{''} held by Forestry Department of West Java Province in 2007. The aims of this study were to assess the changes in mangrove forest area before the program performed and to evaluate the successfulness of the program, using the increasing of mangrove forest area as a parameter. This study was conducted only in Subang and Indramayu Districts of West Java, Indonesia. The assessment was conducted using Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8 OLI acquired in 1996, 2006, and 2016 respectively. For each image, a supervised classification method was performed using open source GRASS GIS software. The resulting maps were then compared to quantify the changes. Field work activity conducted and confirmed the changes that occurred in the study areas. Our study shows that all of the two districts exhibit successfulness of the plantation program.

Researchers have also emphasized the importance of trust as a necessary condition for ensuring the success of virtual organizations. This paper examines the open source software (OSS) `movement' as an example of a virtual organization and proposes a model that runs contrary to the belief that trust is critical for virtual organizations. Instead, I argue that various control mechanisms can ensure the effective performance of autonomous agents who participate in virtual organizations. Borrowing from the theory of the `McDonaldization' of society, I argue that, given a set of practices to ensure the control, efficiency, predictability and calculability of processes and outcomes in virtual organizations, effective performance may occur in the absence of trust. As support for my argument, I employ content analysis to examine a set of published case studies of OSS projects. My results show that, although that trust is rarely mentioned, ensuring control is an important criterion for effective performance within OSS projects. The case studies feature few references to other dimensions of `McDonaldization' (efficiency, predictability and calculability), however, and I conclude that the OSS movement relies on many other forms of social control and self-control, which are often unacknowledged in OSS projects. Through these implicit forms of control, OSS projects are able to secure the cooperation of the autonomous agents that participate in project teams. I conclude by extrapolating from these case studies to other virtual organizations.}, DOI = {10.1046/j.1365-2575.2001.00108.x}, ISSN = {1350-1917}, EISSN = {1365-2575}, Unique-ID = {WOS:000172198800003}, } @article{ WOS:000796618500001, Author = {Paxton, Alexandra and Varoquaux, Nelle and Holdgraf, Chris and Geiger, R.

Taking imatinib (IMA) as an example, we developed an efficient workflow to describe IMA biodegradation with activated sludge (AS) from wastewater treatment plants (WWTP). IMA is a cytostatic pharmaceutical; a selective tyrosine kinase inhibitor used to treat chronic myeloid leukemia. Its reported ecotoxic, endocrine and genotoxic effects imply high risk for aquatic wildlife and human health, however its fate in the environment is not yet well known. The study was conducted in a batch biotransformation setup, at two AS concentration levels and in presence and absence of carbon source. Degradation profiles and formation of IMA transformation products (TPs) were investigated using UHPLC-QqOrbitrap-MS/MS which showed that IMA is readily biodegradable. TPs were determined using multivariate statistical analysis. Eight TPs were determined and tentatively identified, six of them for first time. Hydrolysis of amide bond, oxidation, demethylation, deamination, acetylation and succinylation are proposed as major biodegradation pathways. TP235, the product of amide bond hydrolysis, was detected and quantified in actual wastewaters, at levels around 1 ng/L. This calls for more studies on the environmental fate of IMA in order to properly asses the environmental risk and hazard associated to IMA and its TPs. (c) 2021 The Authors.

This Study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities ire formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success. (C) 2008 Elsevier Inc.

Many individuals and organizations have purchased consumer-grade UAVs, and commonly acquire aerial photographs to map land cover. The resulting ultra-high-resolution (sub-decimeter-resolution) imagery has high information content, but automating the extraction of this information to create accurate, wall-to-wall land-cover maps is quite difficult. We introduce image-processing workflows that are based on open-source software and can be used to create land-cover maps from ultra-high-resolution aerial imagery. We compared four machine-learning workflows for classifying images. Two workflows were based on random forest algorithms. Of these, one used a pixel-by-pixel approach available in ilastik, and the other used image segments and was implemented with R and the Orfeo ToolBox. The other two workflows used fully connected neural networks and convolutional neural networks implemented with Nenetic. We applied the four workflows to aerial photographs acquired in the Great Basin (western USA) at flying heights of 10 m, 45 m and 90 m above ground level. Our focal cover type was cheatgrass (Bromus tectorum), a non-native invasive grass that changes regional fire dynamics. The most accurate workflow for classifying ultra-high-resolution imagery depends on diverse factors that are influenced by image resolution and land-cover characteristics, such as contrast, landscape patterns and the spectral texture of the land-cover types being classified.

It is important to deepen our understanding of spoofing attacks and develop resilient techniques to effectively combat this threat. Detecting and mitigating these attacks requires thorough testing, typically conducted in a laboratory environment through the establishment of a spoofing test-bed. The complexity, cost and resource demands of creating such a test-bed underscore the necessity of utilizing openly available datasets. To address this need, this paper introduces a new GNSS spoofing data repository from Finnish Geospatial Research Institute (FGI) named hereafter as `FGI-SpoofRepo'. This data repository consists of raw In-phase and Quadrature (I/Q) data of live recordings of GPS L1 C/A, Galileo E1, GPS L5, and Galileo E5a signals. These datasets encompass three distinct types of spoofing characteristics (synchronous, asynchronous, and meaconing), making them very useful example candidates of open data for testing the performance of any anti-spoofing techniques (be it detection or mitigation). The inclusion of live signals in multiple GNSS frequencies and the presence of cryptographic signatures in Galileo E1 signal make these datasets potential benchmarks for assessing the resilience performance of multi-frequency multi-constellation receivers. The analysis of the datasets is carried out with an open-source MATLAB-based software-defined receiver, FGI-GSRx. An updated version of FGI-GSRx, equipped with the necessary modifications for processing and analyzing the new datasets, is released alongside the datasets. Therefore, the GNSS research community can utilize the open-source FGI-GSRx or any third-party SDR to process the publicly available raw I/Q data for implementation, testing and validation of any new anti-spoofing technique. The results show that time-synchronous spoofing seamlessly takes over positioning solution, while time-asynchronous spoofing acts as noise or in some cases, completely prevent the receiver from providing a positioning solution. Signal re-acquisition during an ongoing spoofing attack (cold start), the receiver tends to lock onto the spoofing signal with the highest peak, posing a potential threat to GNSS receivers without assisted information. Overall, this research aims to advance the understanding of complex spoofing attacks on GNSS signals, providing insight into enhancing resilience in navigation systems.}, DOI = {10.1007/s10291-024-01719-2}, Article-Number = {176}, ISSN = {1080-5370}, EISSN = {1521-1886}, ResearcherID-Numbers = {Bhuiyan, Zahidul/B-2840-2010 }, ORCID-Numbers = {Islam, Saiful/0000-0002-6658-3427}, Unique-ID = {WOS:001289057200001}, } @article{ WOS:000596039600006, Author = {Tang, Tanya (Ya) and Fang, Eric (Er) and Qualls, William J.}, Title = {MORE IS NOT NECESSARILY BETTER: AN ABSORPTIVE CAPACITY PERSPECTIVE ON NETWORK EFFECTS IN OPEN SOURCE SOFTWARE DEVELOPMENT COMMUNITIES}, Journal = {MIS QUARTERLY}, Year = {2020}, Volume = {44}, Number = {4}, Pages = {1651-1678}, Month = {DEC}, Abstract = {Previous research has predominantly taken a social network perspective suggesting that building more network connections or becoming deeply embedded in a network provides a better position to access network knowledge in open source software communities. This perspective implicitly assumes that accessed network knowledge automatically gets absorbed and transferred to projects, so that building more and deeper network connections is beneficial: Drawing from an absorptive capacity perspective, this research challenges such conventional wisdom, arguing instead that the benefits depend on a project's absorptive capacity. Network connections provide access to external knowledge in the community; the absorption and transfer of this new knowledge require appropriate internal knowledge and developer roles. With longitudinal data collected from 4,518 open source software development projects hosted at Source-Forge, the authors show that knowledge breadth (depth) helps with the absorption of external knowledge achieved from network depth (breadth), but it inhibits the absorption of external knowledge obtained from network breadth (depth). Further, developer roles (e.g., bridge members, role diversity) can mitigate the negative consequences of suboptimal combinations and facilitate effective transfers of absorbed external knowledge across and within projects.

Input data can be imported via CSV or LAS files, providing a 3D point cloud, enhanced with geometric features or spectral information, such as colors from orthophotos or hyperspectral data. cLASpy\_T lets the user run three supervised machine learning algorithms from the scikit-learn API to build automatic classification models: RandomForestClassifier, GradientBoostingClassifier and MLPClassifier. This work presents the general method for classification model design using cLASpy\_T and the software's complete workflow with an example of photogrammetry point cloud classification. Four photogrammetric models of a coastal dike were acquired on four different dates, in 2021.

Through a mixed-method research design consisting of qualitative interviews and a survey of employees of a large telecommunications firm, we find that the organizational innovation to commercially engage in OSS has different impacts on technical and administrative dimensions of different job roles. Accordingly, individuals enacting different job roles are-on average-more or less well aligned with the OSS practice and OSS processes per se. We find that individual-level attributes can counterbalance the job role changes that weaken support for adopting OSS, while perceived organizational commitment has no effect.

Different acquisition modes, such as whole-cell patch-clamp recordings in the current or voltage clamp configuration, capacitance measurements or single channel recordings from cultured cells as well as acute brain slices are routinely performed for these purposes. Nevertheless, multipurpose transparent and adaptable software tools to perform reproducible state-of-the-art analysis of multiple experiment types and to manage larger sets of experimental data are currently unavailable. Methods: Biophysical Essentials (BPE) was developed as an open-source full stack python software for transparent and reproducible analysis of electrophysiological recordings. For validation, BPE results were compared with manually analyzed single-cell patch-clamp data acquired from a human in vitro nociceptor-model and mouse dorsal root ganglia neurons. Results: While initially designed to improve time consuming and repetitive analysis steps, BPE was further optimized as a technical software solution for entire workflow processing including data acquisition, data preprocessing, normalization and visualization and of single recordings up to stacked calculations and statistics of multiple experiments. BPE can operate with different file formats from different amplifier systems and producers. An in-process database logs all analysis steps reproducible review and serves as a central storage point for recordings. Statistical testing as well as advanced analysis functions like Boltzmann-fitting and dimensional reduction methods further support the researchers' needs in projects involving electrophysiology techniques. Conclusions: BPE extends beyond available patch-clamp specific, open source - and commercial analysis tools in particular because of reproducible and sharable analysis workflows. BPE enables full analysis from raw data acquisition to publication ready result visualizations - all within one single program. Thereby, BPE significantly enhances transparency in the analytical process of patch-clamp data analysis. BPEs function scope is completely accessible through an easy-to-use graphical user interface eliminating the need for programing language proficiency as required by many community patch-clamp analysis frameworks and algorithms.}, DOI = {10.1016/j.cmpb.2024.108328}, EarlyAccessDate = {JUL 2024}, Article-Number = {108328}, ISSN = {0169-2607}, EISSN = {1872-7565}, ORCID-Numbers = {Zimmermann, David/0009-0008-0183-7298 Kress, Michaela/0000-0002-8921-7470}, Unique-ID = {WOS:001276436300001}, } @article{ WOS:000329005000006, Author = {Li, Yan and Tan, Chuan-Hoo and Yang, Xue}, Title = {It is all about what we have: A discriminant analysis of organizations' decision to adopt open source software}, Journal = {DECISION SUPPORT SYSTEMS}, Year = {2013}, Volume = {56}, Pages = {56-62}, Month = {DEC}, Abstract = {This research reasons that human capital, that is, knowledge, skills, experience, abilities, and capacities possessed by employees, plays a vital role in the adoption of open source software CUSS) by organizations.

This tool chain can largely replace current routines by importing data, producing analyses, and generating publication-quality graphics. An electronic notebook like Jupyter allows these analyses, along with documentation of procedures, to display locally or remotely in an internet browser, which can be saved as an HTML, PDF, or other file format for sharing with team members and the scientific community.

To successfully run IT business, it is important to properly understand the OSS development status. Having a proper understanding of development status is necessary to evaluate and predict the product quality. However, the OSS development status is not easy to understand, because it is often concurrently developed by many distributed contributors, and its developmental structure is complicated. To aid the understanding of the development status, there is an approach that models the trend of source code change events (evolution) with a growth curve. Although an application of growth curves seems to be a promising approach, there has been a big issue that a single growth curve is often unsuitable for modeling the whole evolution because of its complex evolutionary behavior. This paper proposes a multistage model that divides the whole development period into some stages, and applies a different growth curve to a different stage.

Unlike existing AI tools in education, LAMB provides a comprehensive framework that addresses privacy concerns, ensures alignment with institutional policies, and promotes using authoritative sources. LAMB leverages the capabilities of large language models and associated generative artificial intelligence technologies to create generative intelligent learning assistants that enhance educational experiences by providing personalized learning support based on clear directions and authoritative fonts of information. Key features of LAMB include its modular architecture, which supports prompt engineering, retrieval-augmented generation, and the creation of extensive knowledge bases from diverse educational content, including video sources. The development and deployment of LAMB were iteratively refined using a minimum viable product approach, exemplified by the learning assistant: ``Macroeconomics Study Coach,{''} which effectively integrated lecture transcriptions and other course materials to support student inquiries. Initial validations in various educational settings demonstrate the potential that learning assistants created with LAMB have to enhance teaching methodologies, increase student engagement, and provide personalized learning experiences. The system's usability, scalability, security, and interoperability with existing LMS platforms make it a robust solution for integrating artificial intelligence into educational environments. LAMB's open-source nature encourages collaboration and innovation among educators, researchers, and developers, fostering a community dedicated to advancing the role of artificial intelligence in education.

In doing so, it offers new insights into the association between open innovation and diversification. We rely on arguments inspired by the literature and evidence collected through interviews with OSS SMEs' top managers to investigate factors that favor or hinder within-industry diversification. First, in line with the mainstream diversification literature, we focus attention on the role of firm size. Second, in the spirit of the open innovation research, we concentrate on the mechanisms that OSS SMEs put in place to get access to the external resources of the OSS community. Econometric evidence on 100 European OSS SMEs shows that firm size is negatively associated to within-industry diversification, while OSS SMEs that have contributed to a larger number of OSS projects have a more diversified portfolio of software products. Furthermore, we provide preliminary evidence that the practice of authorizing firm programmers to contribute autonomously to OSS projects of their own choice during working hours may be positively associated to within-industry diversification only if OSS SMEs possess adequate internal technological resources.

In the last decade, it was successfully applied for arthropod identification, allowing researchers to distinguish vectors from non-vectors of infectious diseases. However, identification failures are not rare, hampering its wide use. Failure is generally attributed either to the absence of respective counter species MS spectra in the database or to the insufficient quality of query MS spectra (i.e., lower intensity and diversity of MS peaks detected). To avoid matching errors due to non-compliant spectra, the development of a strategy for detecting and excluding outlier MS profiles became compulsory. To this end, we created MSProfileR, an R package leading to a bioinformatics tool through a simple installation, integrating a control quality system of MS spectra and an analysis pipeline including peak detection and MS spectra comparisons. MSProfileR can also add metadata concerning the sample that the spectra are derived from.

This study is a mixed: methods investigation of the socialization factors that influence contributor performance in large FOSS projects. A qualitative research component resulted into the development of a FOSS socialization framework as well as into the identification of key FOSS project citizenship behaviors. A conceptual model was then developed and empirically examined with 367 contributors from 12 large FOSS projects. The model hypothesizes the mediating effect of two proximal socialization variables, social identification and social integration, between FOSS newcomer socialization factors and contributor performance (conceptualized as task performance and community citizenship behaviors). The results demonstrate the influence of social identification and social integration in predicting contributor performance, as well as the importance of key socialization factors that are: task segregation, task purposefulness, interaction intensity, and supportiveness.

This paper investigates and presents common industry requirements for FLOSS governance tools, followed by an evaluation of the suggested requirements by matching them with the features of existing tools. We chose 10 industry leading companies through polar theoretical sampling and interviewed their FLOSS governance experts to derive a theory of industry needs and requirements for tooling.

This study examines the simultaneous effects of external and internal sources of social capital, in the form of participant and project differences, and examines how they interact to influence OSS project success. We propose a taxonomy of participant differences (language, role, and contribution) and project differences (development environment and connectedness) and postulate their main and moderating effects on project success. Using a four-year panel data set of 329 SourceForge projects, we show that development environment difference has a curvilinear relationship with success and that connectedness reduces the positive impact of role and contribution diversity on project success. We also show that when development environment difference is moderate, the impact of role diversity is the most positive.

To evaluate the model we conducted a survey with over 100 FLOSS episodic volunteers. We observe that three of our model constructs (social norms, satisfaction and community commitment) are all positively associated with volunteers' intention to remain, while the two other constructs (psychological sense of community and contributor benefit motivations) are not. Furthermore, exploratory clustering on unobserved heterogeneity suggests that there are four distinct categories of volunteers: satisfied, classic, social and obligated.

The existence and continuation of OSS relies on the contribution of private resources - personal time, volunteer energy, and effort of numerous actors (e.g., software developers' time as a common-pool resource) - to public goods, the benefits of which are enjoyed by everyone. Nonprofit organizations such as the Apache Software Foundation (ASF) attempt to aid this process by providing various collective services to OSS projects, acting as a second-order actor in the production of the public good. To this end, the ASF Incubator has created policies - essentially rules or norms - that serve to protect its interests and, as they say, increase the sustainability of the projects. Each policy requires investment by ASF (in terms of money or the use of volunteer time) or an incubating project (in terms of taking project personnel time), the benefits of which can accrue to either party. Such policies may impose additional costs on incubating projects, leading to a decreased production of the OSS public good. Using the ASF Incubator policy documents, we construct a dataset that records who - ASF or an incubating project - bears the cost and who enjoys the benefit of each policy and procedure. We can code most policy statements as costing one party and benefiting one party. The distribution of costs and benefits according to party indicates whether the second-order actor is contributing to an increase in the public good and if they are doing so sustainably. Through a two-way ANOVA, we characterize the impact of ASF policies on the production of public goods (OSS). Being a part of ASF imposes some costs on projects, but these costs may make projects more sustainable. Our analysis shows that the distribution of costs and benefits is fairly symmetric between the ASF and incubating projects. Thus, the configuration of policies or the ``institutional design{''} of the ASF could aid in producing the OSS public good by providing services that projects require.}, DOI = {10.5334/ijc.1176}, ISSN = {1875-0281}, ORCID-Numbers = {Atkisson, Curtis/0000-0003-3575-6871}, Unique-ID = {WOS:000793619500001}, } @article{ WOS:000261378500013, Author = {Thompson, Jason}, Title = {Free online games, open source software and library technical roles, what do they have in common?}, Journal = {PROFESIONAL DE LA INFORMACION}, Year = {2008}, Volume = {17}, Number = {6}, Pages = {679-680}, Month = {NOV-DEC}, Abstract = {Consumers are coming to expect a more flexible approach to purchasing software applications, with upgrades and add-ons being available as downloads rather than physically going to a shop to make their purchase.

The morphometric quantification of these networks is essential to study the cellular phenotype. Commonly, the quantitative measurements are performed on 2D projections of the image stack, resulting in the loss of information in the third dimension. Currently available 3D image analysis tools rely on manual interactions with the software and are therefore not feasible for large datasets. Findings Here we present Qiber3D, an open-source image processing toolkit. The software package includes the essential image analysis procedures required for image processing, from the raw image to the quantified data. Optional pre-processing steps can be switched on/off depending on the input data to allow for analyzing networks from a variety of sources. Two reconstruction algorithms are offered to meet the requirements for a wide range of network types. Furthermore, Qiber3D's rendering capabilities enable the user to inspect each step of the image analysis process interactively to ensure the creation of an optimal workflow for each application. Conclusions Qiber3D is implemented as a Python package, and its source code is freely available at https://github.com/theia-dev/Qiber3D.

This is especially true when considering individual and population-level diversity, where the myriad combinations of real-world exposures magnify the combinatoric challenges. The GeoTox framework offers a tractable solution by integrating geospatial exposure data from source-to-outcome in a series of modular, interconnected steps.ResultsHere, we introduce the GeoTox open-source R software package for characterizing the risk of perturbing molecular targets involved in adverse human health outcomes based on exposure to spatially-referenced stressor mixtures. We demonstrate its usage in building computational workflows that incorporate individual and population-level diversity. Our results demonstrate the applicability of GeoTox for individual and population-level risk assessment, highlighting its capacity to capture the complex interplay of environmental stressors on human health.ConclusionsThe GeoTox package represents a significant advancement in environmental risk characterization, providing modular software to facilitate the application and further development of the GeoTox framework for quantifying the relationship between environmental exposures and health outcomes. By integrating geospatial methods with cutting-edge exposure and toxicological frameworks, GeoTox offers a robust tool for assessing individual and population-level risks from environmental stressors.

This study aims to explore the ingestion of digital archives into an approved long-term storage system through FOSS in South Africa with the view of developing a framework.Design/methodology/approachThe study adopted a qualitative research approach to collect data through interviews with purposively selected participants (records managers, archivists and IT officials) from national government departments that have implemented records management systems for digital curation of archives, as well as the National Archives and Records Services of South Africa (NARSSA), which regulates archives and records management, and the State Information Technology Agency, which regulates information technology in government.FindingsThe findings of the study suggest that the systematic transfer of digital materials from public entities to NARSSA, as required by statute, has not taken place.Research limitations/implicationsThe study specifically targeted national government departments that have implemented digital archives and records management systems. Consequently, perspectives from departments that have not implemented these solutions were excluded.Originality/valueA framework is proposed for the transfer of digital archives, using interoperable FOSS, from government agencies responsible for records management to NARSSA for archival preservation. This framework, it is hoped, will facilitate infrastructure and skills development in the management of records and preservation of archives through open platforms.}, DOI = {10.1108/CC-02-2024-0003}, EarlyAccessDate = {SEP 2024}, ISSN = {2514-9326}, ResearcherID-Numbers = {Ngoepe, Mpho/ABC-2938-2020 }, ORCID-Numbers = {Shekgola, Mahlatse Moses/0000-0003-2494-3276}, Unique-ID = {WOS:001318862600001}, } @inproceedings{ WOS:000426130600040, Author = {Calderon Urrutia, Jose Wilber and Osegueda Miranda, Jose Rigoberto}, Book-Group-Author = {IEEE}, Title = {Recorder of Climatic Variables and River Levels using Open Source Software and Hardware and Mobile Phone}, Booktitle = {2017 IEEE 37TH CENTRAL AMERICA AND PANAMA CONVENTION (CONCAPAN XXXVII)}, Year = {2017}, Note = {37th IEEE Central America and Panama Convention (CONCAPAN), Managua, NICARAGUA, NOV 15-17, 2017}, Organization = {IEEE}, Abstract = {The use of electronics as an instrument in the monitoring of climatic variables and the response of natural systems to these variables, has contributed enormously to providing information in assessing natural resources, as well as for natural disaster risk management.

We developed Chipper, a Python-based software to semi-automate both the segmentation of acoustic signals and the subsequent analysis of their frequencies and durations. For avian recordings, we provide widgets to best determine appropriate thresholds for noise and syllable similarity, which aid in calculating note measurements and determining song syntax. In addition, we generated a set of synthetic songs with various levels of background noise to test Chipper's accuracy, repeatability and reproducibility. Chipper provides an effective way to quickly generate quantitative, reproducible measures of birdsong. The cross-platform graphical user interface allows the user to adjust parameters and visualize the resulting spectrogram and signal segmentation, providing a simplified method for analysing field recordings. Chipper streamlines the processing of audio recordings with multiple user-friendly tools and is optimized for multiple species and varying recording qualities.

Modern EHRs consist of complex software code with extensive local configurability options, which can introduce defects. Defects in clinical decision support (CDS) tools are surprisingly common. Feasible approaches to prevent and detect defects in EHR configuration, including CDS tools, are needed. In complex software systems, use of test-driven development and automated regression testing promotes reliability. Test-driven development encourages modular, testable design and expanding regression test coverage. Automated regression test suites improve software quality, providing a ``safety net{''} for future software modifications. Each automated acceptance test serves multiple purposes, as requirements (prior to build), acceptance testing (on completion of build), regression testing (once live), and ``living{''} design documentation. Rapid-cycle development or ``agile{''} methods are being successfully applied to CDS development. The agile practice of automated test-driven development is not widely adopted, perhaps because most EHR software code is vendor-developed. However, key CDS advisory configuration design decisions and rules stored in the EHR may prove amenable to automated testing as ``executable requirements.{''} Objective: We aimed to establish feasibility of acceptance test-driven development of clinical decision support advisories in a commonly used EHR, using an open source automated acceptance testing framework (FitNesse). Methods: Acceptance tests were initially constructed as spreadsheet tables to facilitate clinical review. Each table specified one aspect of the CDS advisory's expected behavior. Table contents were then imported into a test suite in FitNesse, which queried the EHR database to automate testing. Tests and corresponding CDS configuration were migrated together from the development environment to production, with tests becoming part of the production regression test suite. Results: We used test-driven development to construct a new CDS tool advising Emergency Department nurses to perform a swallowing assessment prior to administering oral medication to a patient with suspected stroke. Test tables specified desired behavior for (1) applicable clinical settings, (2) triggering action, (3) rule logic, (4) user interface, and (5) system actions in response to user input. Automated test suite results for the ``executable requirements{''} are shown prior to building the CDS alert, during build, and after successful build. Conclusions: Automated acceptance test-driven development and continuous regression testing of CDS configuration in a commercial EHR proves feasible with open source software. Automated test-driven development offers one potential contribution to achieving high-reliability EHR configuration. Vetting acceptance tests with clinicians elicits their input on crucial configuration details early during initial CDS design and iteratively during rapid-cycle optimization.}, DOI = {10.2196/medinform.9679}, Article-Number = {e23}, EISSN = {2291-9694}, ResearcherID-Numbers = {Kannan, Vaishnavi/AAX-2334-2020 Basit, Mujeeb/ABH-3084-2021 }, ORCID-Numbers = {Parks, Cassandra/0000-0002-2787-7588 Kannan, Vaishnavi/0000-0002-3042-5427 Basit, Mujeeb/0000-0002-4948-6158 Willett, DuWayne/0000-0002-3087-4193}, Unique-ID = {WOS:000438272800007}, } @article{ WOS:000301203900004, Author = {Hintzen, Niels T. and Bastardie, Francois and Beare, Doug and Piet, Gerjan J. and Ulrich, Clara and Deporte, Nicolas and Egekvist, Josefine and Degel, Henrik}, Title = {VMStools: Open-source software for the processing, analysis and visualisation of fisheries logbook and VMS data}, Journal = {FISHERIES RESEARCH}, Year = {2012}, Volume = {115}, Pages = {31-43}, Month = {MAR}, Abstract = {VMStools is a package of open-source software, build using the freeware environment R. specifically developed for the processing, analysis and visualisation of landings (logbooks) and vessel location data (VMS) from commercial fisheries.

The three sub-pixel correlators used are: COSI-Corr - developed by Caltech, a free, closed-source correlator, dependent on commercial software (ENVI) and widely used by the geoscience community for measuring ground displacement; Medicis - developed by CNES, also a closed-source correlator capable of measuring this type of deformation; and MicMac - developed by IGN, the free open-source correlator we study and tune for measuring fine ground displacements. We measured horizontal ground deformation using these three correlators on SPOT images in three study cases: the 2001 Kokoxili earthquake, the 2005 dyke intrusion in the Afar depression and the 2008 Yutian earthquake.

In this paper, we propose a novel hierarchical meshing strategy leading to an important reduction of the computation time. The time complexity of the algorithm is shown to be O(root N), where N is the requested number of facets of the mesh of the ship's surface.

The results are compared with experimental data and CFD using the commercial software Fluent, both previously reported in the open literature. This work studies the fluid flow pattern around a tube with six 45-degree-angled fins, and the working fluid, air, is considered as an incompressible fluid. Special attention is paid to calculating the pressure coefficient distribution for the internal and external surfaces of the inclined fins. Open-source platforms allow researchers to visualize how the airflow interacts with the cylinder and the fin surfaces to form a fluid structure, formerly known as a horseshoe vortex system. The findings of the analysis of flow dynamics in the channel between inclined fins and in the wake help explain the results obtained in experimental tests and are relevant for the configuration of a bank of tubes with inclined fins.}, DOI = {10.3390/fluids7080282}, Article-Number = {282}, EISSN = {2311-5521}, ResearcherID-Numbers = {Gabbasov, Ruslan/JUV-7109-2023 Carvajal-Mariscal, Ignacio/IWV-4018-2023 Real, Cesar/A-1467-2011 TREJO, JESUS ISIDRO/GQB-1604-2022 Gonzalez-Trejo, Jesus/B-3001-2019 Carvajal-Mariscal, Ignacio/V-7349-2018 Real-Ramirez, Cesar Augusto/K-7259-2013 }, ORCID-Numbers = {Klapp, Jaime/0000-0003-1828-9183 Gonzalez-Trejo, Jesus/0000-0003-4702-3464 Carvajal-Mariscal, Ignacio/0000-0003-2641-9398 Real-Ramirez, Cesar Augusto/0000-0003-0376-3575 Gabbasov, Ruslan/0000-0002-1578-1589}, Unique-ID = {WOS:000846028500001}, } @article{ WOS:000272105500003, Author = {Kozicki, J. and Donze, F.

The purpose of this paper is to describe the software architecture. Design/methodology/approach - The DEM chosen uses position, orientation, velocity and angular velocity as independent variables of simulated particles which are subject to explicit leapfrog time-integration scheme (Lagrangian method). The three-dimensional dynamics equations based on the classical Newtonian approach for the second law of motion are used. The track of forces and moments acting on each particle is kept at every time step. Contact forces depend on the particle geometry overlap and material properties. The normal, tangential and moment components of interaction force are included. Findings - An effort is undertaken to extract the underlying object oriented abstractions in the DEM. These abstractions are implemented in C++, conform to object oriented design principles and use design patterns. Based on that, a software framework is developed in which the abstractions provide the interface where the modelling methods can be plugged-in. Originality/value - The resulting YADE-OPEN DEM framework is designed in a generic way which provides great flexibility when adding new scientific simulation code. Some of the advantages are that numerous simulation methods can be coupled within the same framework while plug-ins can import data from other software. In addition, this promotes code improvement through open-source development and allows feedback from the community. However implementing such models requires that one adheres to the framework design and the YADE framework is a new emerging software.

Accordingly, the study unearthed two different but conjoint ways (i.e., direct and indirect) in which intellectual capital impacts COSS company's success. On the one hand, relational capital one of the intellectual capital components directly affects COSS company's success. On the other hand, relational and structural capital indirectly affect COSS company success through human capital, which, in turn, is itself mediated by software quality in a sequential mediation model.

Our work comprehensively investigates cross-project code clones in open-source software for Internet of Things (IoT) systems across multiple programming languages. This work addresses the prevalence of cross-project code clones in IoT systems and their impact on software maintainability. We collected 122 IoT system repositories in nine languages from GitHub and grouped them according to their primary functionality in IoT systems. We used MSCCD, a multilingual code clone detector to detect Type-3 code clones for each group. The results show that cross-project clones exist in more than 30\% of the projects, particularly in communication-related functionalities. We tracked the historical evolution of these clones and classified them according to the revision history and changing trend of similarity. The results show that 95\% cross-project clones are untouched. Moreover, clones with decreasing similarities were over 72\%. Therefore, the same clone detector may no longer detect these clones. We also investigated whether these cross-project code clones lead to defect propagation by analyzing the commit message to determine the commits that fixed a defect. We identified nine defect propagation instances, of which seven remain unfixed. Our work contributes to understanding cross-project code clones, highlighting the importance of automated clone management tools for improving the quality and security of IoT system software to mitigate the risks associated with unresolved defects and inconsistencies in IoT software development.}, DOI = {10.1109/ACCESS.2024.3506013}, ISSN = {2169-3536}, ORCID-Numbers = {Matsubara, Yutaka/0000-0002-1111-0761 Takada, Hiroaki/0000-0003-3544-2397}, Unique-ID = {WOS:001373836200027}, } @article{ WOS:000272915200006, Author = {Raja, Uzma and Tretter, Marietta J.}, Title = {Antecedents of open source software defects: A data mining approach to model formulation, validation and testing}, Journal = {INFORMATION TECHNOLOGY \& MANAGEMENT}, Year = {2009}, Volume = {10}, Number = {4, SI}, Pages = {235-251}, Month = {DEC}, Note = {2nd INFORMS Workshop on Artificial Intelligence and Data Mining, Seattle, WA, NOV 03, 2007}, Organization = {INFORMS}, Abstract = {This paper develops tests and validates a model for the antecedents of open source software (OSS) defects, using Data and Text Mining.

In this study, some benchmark problems have been solved with DualSPHysics to validate the estimation of wave impact pressure with violent breaking waves. We have demonstrated three main results: (i) as an alternative to the artificial viscosity traditionally used in DualSPHysics, a laminar viscosity model can also well reproduce the solutions to the existing benchmark problems in a violent flow field with the modified dynamic boundary condition; (ii) the dynamics of the gas phase is essential in the calculation of wave breaking with rapid gate opening; and (iii) if the density diffusion parameter is too large, the impact pressure may be underestimated. The practical contribution by this study is to find that DualSPHysics well reproduces complex breaking waves, including multi-phase gas-liquid flows, and that the wave impact pressure is accurate by comparison with existing experimental results.

In this study, the 2017 image from the Sentinel-2A Satellite was utilized to demonstrate the land cover classification analysis in Iskandar Malaysia. Usually, land use classification analysis is conducted through proprietary GIS software. However, this decade shows the advancement in software development, thus the emerging of free/open source software in the geospatial world. Hence, to execute land cover analysis using the Unsupervised Classification technique, the proprietary GIS software (ArcGIS) and free/open source software (QGIS) were deployed. Then, the examination of accuracy assessment was carried out for the selected software. The sum of 250 random points was established for the assessment purpose. The results showed the overall accuracy for ArcGIS and QGIS were 82.80\% and 80.40\% respectively. The kappa coefficient for ArcGIS was 0.7395, while kappa coefficient for QGIS was 0.7094. Besides that, ArcGIS demonstrated better producer's accuracy in the forest and agriculture land covers classification. Meanwhile, QGIS exhibited better producer's accuracy in the built-up and water features classification.

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community.

The influence of `digital sovereignty' in the EU's Cybersecurity Strategy on cybersecurity of open-source software}, Journal = {COMPUTER LAW \& SECURITY REVIEW}, Year = {2025}, Volume = {56}, Month = {APR}, Abstract = {`Digital sovereignty' is the geopolitical mantra of the moment. A key agent of that policy shift, the European Union ('EU') has increasingly embraced `digital sovereignty' as both the ideological foundation and impetus for building its digital future in accordance with `European values and principles,' often driven by and intersecting with cybersecurity concerns as articulated in its 2020 Cybersecurity Strategy for the Digital Decade ('Strategy'). Yet it is impossible to consider cybersecurity without open-source software ('OSS'). Increasingly, the EU, USA and other Governments have recognised that fact in the wake of HeartBleed and Log4j incidents. OSS' decentralised governance and ubiquity, underpinning most software worldwide, may amplify vulnerabilities and adverse effects of cyberattacks, whilst its typically collaborative model of development and innovation often fosters valuable, open cybersecurity solutions. In navigating that policy tightrope of OSS as a double-edged sword for cybersecurity, the EU has adopted `closed' language of `digital sovereignty' that is ostensibly contrary to the `open' nature of OSS. That rhetorical duality is particularly pronounced since the EU described OSS as a tool for realising its `digital sovereignty,' in addition to policy support for `a global, open, interoperable cyberspace' alongside the pursuit of `digital sovereignty.' While there is a epistemic gap in understanding the relationship between the EU's rhetoric of `digital sovereignty' and reality, nascent studies indicate that it has a tangible effect on policy change in multiple digital spheres, generally furthering a degree of `control.' However, that relationship within the OSS cybersecurity context has underexplored and poorly understood, although that policy is a priority for the EU and may bear significant implications for OSS globally. Particularly analyzing the Cyber Resilience Act ('CRA') as key means for implementing the EU's Strategy and its first cybersecurity legislation that would comprehensively engage OSS if adopted by the Council, this article argues that the EU's desire to strengthening cybersecurity in OSS is generally welcome. Yet there is an ostensibly a disjunct between `digital sovereignty' that underpins that legislation and OSS cybersecurity, with too much control of OSS potentially proving counterproductive for EU cybersecurity. This paper illustrates that (i) it is imperative for the EU to address OSS cybersecurity; (ii) yet the lens of digital sovereignty is ostensibly a rough fit for that approach, considering OSS' philosophy and practice; and (iii) based on the CRA, EU's practice of translating `digital sovereignty' into policy change is mixed, leaving uncertain ramifications for OSS cybersecurity in the EU and beyond. On the one hand, it moves towards more `control' at least in determining definitional parameters and power dynamics with novel `stewardship' positions for certain OSS entities. That said, the EU generally seeks to leverage OSS to further their regional embrace of OSS rather than to exclude others. Ultimately, the EU has a valuable leadership opportunity to drive forward solutions to OSS cybersecurity in collaboration with others whilst avoiding fragmentation, keeping doors open in recognising that global challenges demand global solutions.

With their fluid membership, such communities often rely on engaging the commitment of developers to their cause. Given the changing nature of OSS communities, developers face barriers in appreciating appropriate ways of contributing to the collaborative effort. Such uncertainty about how to contribute results in OSS communities losing developers as they devote their attention to other, more welcoming, communities. In this research, we draw upon uncertainty reduction theory to argue that developers have two alternative avenues at their disposal to gain certainty about how to contribute: passive and interactive. Leveraging the person-environment fit perspective, we argue that congruence and incongruence in the OSS values of a developer and an OSS community serve as an avenue for passive approaches to gaining certainty, to the degree that appropriate ways of contributing are encoded in these values. Further, leveraging social network theory, we argue that centrality within a community's communication network constitutes an avenue for interactive approaches for gaining certainty about how to contribute. Using polynomial regression analysis, we analyze survey and archival data from 410 developers in an OSS community. Results suggest that developer centrality moderates the impact of congruence and incongruence in OSS values on commitment. Moreover, commitment fully mediates the impact of OSS value congruence and incongruence on developer contribution activity.

Specifically, we compared the accuracies of the model using the light gradient boosted machine (LightGBM), a gradient boosting decision tree (GBDT) algorithm, with those of previous models. The experimental results suggested the potential to develop a QSPR model that will produce highly accurate Koc values using molecular descriptors and physicochemical properties. Unlike previous studies, the use of a combination of LightGBM, OPERA and Mordred enables the prediction of Koc for many chemicals with high accuracy. In this study, OPERA was used to calculate the physicochemical properties, and Mordred was used to calculate molecular descriptors. The wide range of chemicals covered by OPERA and Mordred enables the analysis of a diverse range of chemical compounds. We also report a method to tune the LightBGM program. The use of fast-processing software, such as LightGBM, enables parameter tuning of a method required to obtain best performance.

Our findings indicate that a greater amount of policy over a governed topic doesn't elicit more governed activity on that topic, but does predict greater internalization by community members. Moreover, alignment of community operations with foundation governance, be it dedicating their governance focus or adopting policy along topics seeing greater policy-making, has limited association with project outcomes.}, DOI = {10.1145/3613904.3641980}, ISBN = {979-8-4007-0330-0}, ResearcherID-Numbers = {Frey, Seth/AAF-8499-2021 }, ORCID-Numbers = {Atkisson, Curtis/0000-0003-3575-6871}, Unique-ID = {WOS:001255317901049}, } @inproceedings{ WOS:000306295800030, Author = {Laisne, Jean-Pierre and Lago, Nelson and Kon, Fabio and Coca, Pedro}, Editor = {Agerfalk, P and Boldyreff, C and GonzalezBarahona, JM and Madey, GR and Noll, J}, Title = {A Network of FLOSS Competence Centres}, Booktitle = {OPEN SOURCE SOFTWARE: NEW HORIZONS}, Series = {IFIP Advances in Information and Communication Technology}, Year = {2010}, Volume = {319}, Pages = {348-353}, Note = {6th International Conference on Open Source Systems (OSS 2010), Notre Dame, IN, MAY 30-JUN 02, 2010}, Organization = {Int Federat Informat Proc Work Grp 2 13}, Abstract = {The goal of a Network of Competence Centers is to provide to FLOSS users, developers, and consumers, high-quality resources and expertise on the various topics related to FLOSS.

Each Competence Centre acts in its geographical region to increase the awareness of FLOSS and to better prepare the IT workforce for developing and using FLOSS based solutions. As of 2009, the process for Competence Centre creation is sustainable and reusable; guidelines for establishing proposals and opening new Competence Centres have been created, and promotion of Qualipso Competence Centres is done world wide from India to USA thanks to key initiatives such as the Open World Forum and the FLOSS Competence Centre Summit.

Metabolites are generally annotated with various database or structure based identifiers. Metabolite annotations in metabolic reconstructions may be incorrect or incomplete and thus need to be updated prior to their use. Genome-scale metabolic reconstructions generally include hundreds of metabolites. Manually updating annotations is therefore highly laborious. This prompted us to look for open-source software applications that could facilitate automatic updating of annotations by mapping between available metabolite identifiers. We identified three applications developed for the metabolomics and chemical informatics communities as potential solutions. The applications were MetMask, the Chemical Translation System, and UniChem. The first implements a ``metabolite masking{''} strategy for mapping between identifiers whereas the latter two implement different versions of an InChI based strategy. Here we evaluated the suitability of these applications for the task of mapping between metabolite identifiers in genome-scale metabolic reconstructions. We applied the best suited application to updating identifiers in Recon 2, the latest reconstruction of human metabolism. Results: All three applications enabled partially automatic updating of metabolite identifiers, but significant manual effort was still required to fully update identifiers. We were able to reduce this manual effort by searching for new identifiers using multiple types of information about metabolites. When multiple types of information were combined, the Chemical Translation System enabled us to update over 3,500 metabolite identifiers in Recon 2. All but approximately 200 identifiers were updated automatically. Conclusions: We found that an InChI based application such as the Chemical Translation System was better suited to the task of mapping between metabolite identifiers in genome-scale metabolic reconstructions. We identified several features, however, that could be added to such an application in order to tailor it to this task.}, DOI = {10.1186/1758-2946-6-2}, Article-Number = {2}, ISSN = {1758-2946}, ResearcherID-Numbers = {Fleming, Ronan/ABC-4093-2021 Thiele, Ines/A-7629-2014 }, ORCID-Numbers = {Thiele, Ines/0000-0002-8071-7110 Fleming, Ronan MT/0000-0001-5346-9812}, Unique-ID = {WOS:000331945300001}, } @article{ WOS:000301571400008, Author = {Piva, Evila and Rentocchini, Francesco and Rossi-Lamastra, Cristina}, Title = {Is Open Source Software about Innovation?

However, open-source software that is capable of VA processing in real-time mode based on single- and dual-frequency multi-GNSS observations is scarce. In view of this fact, we have developed an open-source VA processing software called PPPH-VA that can evaluate single- and dual-frequency multi-GNSS observations in real-time mode. PPPH-VA is developed in the MATLAB environment, and it can simultaneously process GPS, GLONASS, Galileo, BeiDou-2, and BeiDou-3 data with the VA technique in real-time mode, employing both single- and dual-frequency observations. We evaluated PPPH-VA using shake table experiments based on real data, and the results demonstrate that it provides high accuracy in terms of detection of dynamic displacements. Toolbox can successfully detect the dominant frequencies of short-term dynamic behaviors and is capable of determining the amplitude values corresponding to the peak frequency at the sub-mm level.

We compare our quotation-based analysis with a more conventional, thread-based analysis of the (reply-to) links between messages. The advantages of a quotation-based analysis over a thread-based analysis are outlined.

We address this gap by drawing on the sociological theory of community markers. The three community markers in the context of OSS are loyalty, ideology, and identification. We also draw on marketing literature to propose four contributory behaviors of passive users of OSS that we theorize to be impacted by the community markers: user brand-extension, word-of-mouth, endorsement, and community involvement.

To better visualize the failure progression, the final model excludes these virtual cells from the representation. The functionality of the algorithm is tested through a series of two-dimensional simulations on three different geometries with a well-known behavior under uniaxial tension. Moreover, the failure response of a three-dimensional lattice structure is numerically investigated and compared against experimental data. The results of the two-dimensional simulations showed the capability of the algorithm to predict the onset of failure, crack nucleation, and fracture growth. Similarly, the onset and the initial fracture region were accurately captured in the three-dimensional case, with some convergence issues that prevent the visualization of the fracture growth.

Based on several years of engaged research with FLOSS projects, we characterize three gatekeeping tactics in FLOSS projects: non-response, social exclusion, and false acceptance. They all have hindered usability work. We also offer examples of usability specialists and their contributions succeeding in avoiding these gatekeeping tactics in FLOSS projects. This paper provides an important contribution to the boundary management literature through detailed examination of gatekeeping tactics in action, as well as to the Human Computer Interaction literature interested in contributing to FLOSS projects through usability work.}, DOI = {10.1007/978-3-319-22698-9\_2}, ISSN = {0302-9743}, EISSN = {1611-3349}, ISBN = {978-3-319-22698-9; 978-3-319-22697-2}, ResearcherID-Numbers = {Rajanen, Mikko/K-8465-2013 }, ORCID-Numbers = {Rajanen, Mikko/0000-0002-3281-7029 Lanamaki, Arto/0000-0003-3355-802X}, Unique-ID = {WOS:000363807600002}, } @inproceedings{ WOS:000848100000006, Author = {Chidoori, Cuthbert and Van Belle, Jean-Paul}, Book-Group-Author = {IEEE}, Title = {Attitudes Towards the Uptake of Open Source Software by Small and Medium Enterprises in the Western Cape, South Africa}, Booktitle = {2018 CONFERENCE ON INFORMATION COMMUNICATIONS TECHNOLOGY AND SOCIETY (ICTAS)}, Year = {2018}, Note = {Conference on Information Communications Technology and Society (ICTAS), Durban, SOUTH AFRICA, MAR 08-09, 2018}, Organization = {IEEE}, Abstract = {This paper focuses on the uptake of open source software in small and medium-sized enterprises (SMEs) in the Western Cape. SMEs aim to become more efficient and competitive, but often experience challenges. Open Source Software (OSS) is considered to yield key benefits for SMEs because it is free to access, distribute and customise, peer-reviewed for reliability. However, certain drawbacks can hinder SMEs from adopting OSS such as uncertain support, need for technical skill for usage, incomplete functionality to mention a few. The broadband initiative in the Western Cape looked to enable the access of OSS online through the provision of broadband internet for organisations including SMEs. This research was aimed, through a qualitative analysis, mainly at examining the attitude of SMEs toward OSS by analysing the benefits as well as the drawbacks of using OSS. The research also analysed the effect of the broadband initiative on the attitude of SMEs toward OSS uptake. Additionally, the roles that intermediaries undertake in OSS communities for promoting the uptake of OSS in SMEs, which were investigated were decentralised school, bridging school, arterial school, communities of practice and ecosystems school.

The SAA captures and scores different aspects of human singing ability and melodic memory in the context of item response theory. Taking perspectives from both melodic recall and singing accuracy literature, we present results from two online experiments (N = 247; N = 910). On-the-fly audio transcription is produced via a probabilistic algorithm and scored via latent variable approaches. Measures of the ability to sing long notes indicate a three-dimensional principal components analysis solution representing pitch accuracy, pitch volatility and changes in pitch stability (proportion variance explained: 35\%; 33\%; 32\%). For melody singing, a mixed-effects model uses features of melodic structure (e.g., tonality, melody length) to predict overall sung melodic recall performance via a composite score {[}R(2)c = .42; R(2)m = .16]. Additionally, two separate mixed-effects models were constructed to explain performance in singing back melodies in a rhythmic {[}R(2)c = .42; R(2)m = .13] and an arhythmic {[}R(2)c = .38; R(2)m = .11] condition. Results showed that the yielded SAA melodic scores are significantly associated with previously described measures of singing accuracy, the long note singing accuracy measures, demographic variables, and features of participants' hardware setup.

A FLOSS project usually has a community around its project, organically producing informative resources to describe how, when, and why a particular change occurred in the source code or the development flow. Therefore, when studying this kind of project, collecting and analyzing texts and artifacts can promote a more comprehensive understanding of the phenomenon and the variety of organizational settings. However, despite the importance of examining Grey Literature (GL), such as technical reports, white papers, magazines, and blog posts for studying FLOSS projects, the GL Review is still an emerging technique in software engineering studies, lacking a well-established investigative methodology. To mitigate this gap, we present and discuss challenges and adaptations for the planning and execution of GL reviews in the FLOSS scenario.

This research is based on the rooftop photovoltaic potential (RPVP) of the city of Vitoria-Gasteiz; its ultimate goal is to provide stakeholders with a useful and free tool to calculate a highly accurate RPVP (including different tilt and orientation angles, shadowing, temperature effect, energy return on energy investment (EROI) constraint and available surface area) and based exclusively on free-to-use and open-source software. The EROI constraint is a fundamental step towards the net energy analysis being integrated in the RPVP assessment. This paper is a contribution not only to the application of the EROI constraint, but also to the calculation of this indicator. Results improve on estimates commonly found in the literature. With an EROI > 5 (8.83 on average), Vitoria-Gasteiz has a RPVP of 473 GWh/year, able to supply 38 \% of the total electricity consumption of the city and where 50 \% of total rooftop area is suitable for PV. Therefore, the rooftop PV performance in Vitoria-Gasteiz is sufficiently good to provide the net energy required to sustain today's industrial societies.

Global action plans to address non-communicable diseases (NCDs) recognise the centrality of community engagement to create an enabling environment within which to address risk factors. Study design: In this article, we describe and critically reflect on a cocreated community engagement approach to address type 2 diabetes in the southern plains of Nepal. We coproduced the engagement approach with 40 artists from the Janakpur Women's Development Centre to create an environment for dialogue about diabetes and NCD risk between artists and the general public. Methods: We used participatory action research to produce contextually relevant interactive methods and materials. Methods included artists' peer research to inform creative workshops, a drama performed in 19 villages and a two-day funfair in a public park. We used qualitative and participatory methods to analyse the effect of this engagement and reflect on lessons learned. Results: Around 2000 people saw the drama, and around 4000 people attended the funfair. Community dialogue about prevention of diabetes was facilitated by drama and through games and songs at the funfair. Artists grew confident to interact with their peers and drama audiences about the causes of diabetes and prevention strategies. Despite crowds at the funfair, it was difficult to reach women because the venue was often used by men and boys, and patriarchal norms prevent women from free movement. Village interactions were able to engage a more mixed audience. Conclusion: Innovative, asset-based community engagement about diabetes and other NCDs at scale is possible through locating, building on and strengthening community resources to address local health issues. Engagement could be enhanced by considering the gendered nature of community engagement spaces and by increasing opportunities for interaction between artists and the general public through more intimate and large-scale events.

The INLIGHT strategy is a chemical derivatization technique using hydrazide chemistry to derivatize the reducing end of N-linked glycans and incorporates either a natural (NAT, C-12(6)) or a stable-isotope label (SIL, C-13(6)) to carry out relative quantification.

We integrate the results of a qualitative survey and a big data analysis to understand developer perceptions of corporate engagement and its association with gender and geographic diversity. In the qualitative component, we collected responses from 64 FLOSS contributors to elicit their perspectives on corporate engagement. In the quantitative component, we analyzed GitHub data from 38 projects and 9,990 contributors to investigate differences in participation and diversity based on corporate engagement. We find that contributors vary across dimensions that can inform diversity interventions: stances toward corporations and orientation towards individual/collective benefits. Our results suggest that corporate engagement may limit a project's contributor base and geographic diversity.

The toolbox has been designed for use by staff within the national park, for example, enabling land cover maps to be updated as required in the future. An area of 945 km(2) was mapped using a trained random forest classifier following a classification scheme tailored to the needs of the national park. A 2019 land cover map had an overall user's accuracy of 79\%, with 13 out of 17 land cover classes achieving greater than 70\% accuracy. Spatially, accuracy was related via logistical regression to blue band surface reflectance in the spring and topographic slope derived from LiDAR (1 m resolution), with greater accuracy in steeper terrain and areas exhibiting higher blue reflectance. Between an earlier (2017-2019) and later (2019-2021) time frame, 8\% of pixels changed, most of the change by area occurred in the most common classes.

In contrast to shotgun proteomics, proteins/peptides can be detected directly from biological tissues and correlated to its morphology leading to a gain of crucial clinical information. However, direct identification of the detected molecules is currently challenging for MALDI-IMS, thereby compelling researchers to use complementary techniques and resource intensive experimental setups. Despite these strategies, sufficient information could not be extracted because of lack of an optimum data combination strategy/software. Here, we introduce a new open-source software ImShot that aims at identifying peptides obtained in MALDI-IMS. This is achieved by combining information from IMS and shotgun proteomics (LC-MS) measurements of serial sections of the same tissue. The software takes advantage of a two group comparison to determine the search space of IMS masses after deisotoping the corresponding spectra. Ambiguity in annotations of IMS peptides is eliminated by introduction of a novel scoring system that identifies the most likely parent protein of a detected peptide in the corresponding IMS dataset. Thanks to its modular structure, the software can also handle LC-MS data separately and display interactive enrichment plots and enriched Gene Ontology terms or cellular pathways. The software has been built as a desktop application with a conveniently designed graphic user interface to provide users with a seamless experience in data analysis.

Collectively, these data can be analyzed for such purposes as disease diagnosis or phenotype classification. One family of algorithms that has proven useful for disease classification is based on relative expression analysis and includes the Top-Scoring Pair (TSP), k-Top-Scoring Pairs (k-TSP), Top-Scoring Triplet (TST) and Differential Rank Conservation (DIRAC) algorithms. These relative expression analysis algorithms hold significant advantages for identifying interpretable molecular signatures for disease classification, and have been implemented previously on a variety of computational platforms with varying degrees of usability. To increase the user-base and maximize the utility of these methods, we developed the program AUREA (Adaptive Unified Relative Expression Analyzer)-a cross-platform tool that has a consistent application programming interface (API), an easy-to-use graphical user interface (GUI), fast running times and automated parameter discovery. Results: Herein, we describe AUREA, an efficient, cohesive, and user-friendly open-source software system that comprises a suite of methods for relative expression analysis. AUREA incorporates existing methods, while extending their capabilities and bringing uniformity to their interfaces. We demonstrate that combining these algorithms and adaptively tuning parameters on the training sets makes these algorithms more consistent in their performance and demonstrate the effectiveness of our adaptive parameter tuner by comparing accuracy across diverse datasets. Conclusions: We have integrated several relative expression analysis algorithms and provided a unified interface for their implementation while making data acquisition, parameter fixing, data merging, and results analysis `point- and -click' simple. The unified interface and the adaptive parameter tuning of AUREA provide an effective framework in which to investigate the massive amounts of publically available data by both `in silico' and `bench' scientists.

Hierarchical configurations have been used to structure processes, overcome resistance and get things done. But is deliberate change also possible without formal structures and hierarchical influence? Design/methodology/approach - This longitudinal, qualitative study investigates an open-source software (OSS) community named TYPO3. This case exhibits no formal hierarchical attributes. The study is based on mailing lists, interviews and observations. Findings - The study reveals that deliberate change is indeed achievable in a non-hierarchical collaborative OSS community context. However, it presupposes the presence and active involvement of informal change agents. The paper identifies and specifies four key drivers for change agents' influence. Originality/value - The findings contribute to organisational analysis by providing a deeper understanding of the importance of leadership in making deliberate change possible in non-hierarchical settings. It points to the importance of ``change-by-conviction{''}, essentially based on voluntary behaviour. This can open the door to reducing the negative side effects of deliberate change also for hierarchical organisations.}, DOI = {10.1108/IJOA-08-2016-1050}, ISSN = {1934-8835}, EISSN = {1758-8561}, ORCID-Numbers = {Kesting, Peter/0000-0001-6780-8299}, Unique-ID = {WOS:000402905400011}, } @article{ WOS:000911392500005, Author = {Ayhan, Yavuz and Akbulut, Bilal Bahadir and Sisman, Aybuke Handan and Velibasoglu, Berge}, Title = {PsiNorm: A Fast, Efficient and Free Open-Source Software for Interpreting, Reporting and Archiving Neuropsychological Test Results}, Journal = {TURK PSIKIYATRI DERGISI}, Year = {2022}, Volume = {33}, Number = {4}, Pages = {255-262}, Month = {WIN}, Abstract = {Objective: In many clinics, calculation and interpretation of neuropsychological test results, along with reporting, data organization and archiving of the data are done manually. In this era where most of the similar processes are automated, manual application may result in excessive time consumption, unnecessary use of qualified work-force, and is also open to error. A software that automates these processes for neuropsychological tests used for dementia assessment may overcome these issues. Methods: We aimed to develop a free, open source software not requiring specialized training, which would optimise the calculation, preparation of personal reports and archiving processes of neuropsychological tests, hence would easily be incorporated in to the daily work of psychologists. We've used Python 3.6 as the programming language, and JSON was used as the data interchange format to allow for personal alterations in the content. The tests were selected among those which are in common use for neuropsychological evaluation of adults in Turkey, with available norm values. (Funding: TUBITAK 214S048). Results: PsiNorm was developed, comprising widely used standardized tests for cognitive evaluation of adults in Turkey. The software is lightweight, compatible with most common operating systems, and easy-to-use. We've shown that Psinorm significantly reduced the time required for calculation of percentiles and norms as well as for producing a draft report. The reports are prepared in.txt format and the databases are prepared in MS Excel ve CSV formats. PsiNorm is available freely at psinorm.org. Conclusion: PsiNorm is a free, open-source software which is available for researchers and clinicians who perform neuropsychological tests.

We define the notion of a working rhythm as the average time spent on a commit task and we study the correlation between working rhythm and communication frequency. We build communication networks for code developers, and find that the developers with higher social status, represented by the nodes with larger number of outgoing or incoming links, always have faster working rhythms and thus contribute more per unit time to the projects. We also study the dependency between work (committing) and talk (communication) activities, in particular the effect of their interleaving. We introduce multi-activity time-series and quantitative measures based on activity latencies to evaluate this dependency. Comparison of simulated time-series with the real ones suggests that when work and talk activities are in proximity they may accelerate each other in OSS systems. These findings suggest that frequent communication before and after committing activities is essential for effective software development in distributed systems.}, DOI = {10.1109/SocialInformatics.2012.17}, ISBN = {978-0-7695-5015-2; 978-1-4799-0234-7}, ResearcherID-Numbers = {Barr, Earl T.

The quantification of tumor heterogeneity with molecular images, by analyzing the local or global variation in the spatial arrangements of pixel intensity with texture analysis, possesses a great clinical potential for treatment planning and prognosis. To address the lack of available software for computing the tumor heterogeneity on the public domain, we develop a software package, namely, Chang-Gung Image Texture Analysis (CGITA) toolbox, and provide it to the research community as a free, open-source project. Methods. With a user-friendly graphical interface, CGITA provides users with an easy way to compute more than seventy heterogeneity indices. To test and demonstrate the usefulness of CGITA, we used a small cohort of eighteen locally advanced oral cavity (ORC) cancer patients treated with definitive radiotherapies. Results. In our case study of ORC data, we found that more than ten of the current implemented heterogeneity indices outperformed SUVmean for outcome prediction in the ROC analysis with a higher area under curve (AUC). Heterogeneity indices provide a better area under the curve up to 0.9 than the SUVmean and TLG (0.6 and 0.52, resp.). Conclusions.

Two interpretive case studies on user participation in OSS development are included in this article. The first examines a traditional community OSS development project; the second concentrates on the company OSS development context, the case being a software development unit of a global corporation involved in OSS development. Through analysis of the cases, different forms of participatory design (PD), especially of distributed PD, are identified. Distributed PD is interpreted to include gaining an understanding of users' current practices, redesigning them together with users and gathering feedback from users related to the solutions. Different kinds of roles are available to users, as well as to for intermediaries `representing users'.

Interpreting this data involves inferring the masses and abundances of biomolecules injected into the instrument. Because of the inherent complexity of mass spectral patterns produced by these biomolecules, the analysis is significantly enhanced by using visualization capabilities to inspect and confirm results. In this paper we describe Decon2LS, an open-source software package for automated processing and visualization of high-resolution MS data. Drawing extensively on algorithms developed over the last ten years for ICR2LS, Decon2LS packages the algorithms as a rich set of modular, reusable processing classes for performing diverse functions such as reading raw data, routine peak finding, theoretical isotope distribution modelling, and deisotoping. Because the source code is openly available, these functionalities can now be used to build derivative applications in relatively fast manner. In addition, Decon2LS provides an extensive set of visualization tools, such as high performance chart controls. Results: With a variety of options that include peak processing, deisotoping, isotope composition, etc, Decon2LS supports processing of multiple raw data formats. Deisotoping can be performed on an individual scan, an individual dataset, or on multiple datasets using batch processing. Other processing options include creating a two dimensional view of mass and liquid chromatography (LC) elution time features, generating spectrum files for tandem MS data, creating total intensity chromatograms, and visualizing theoretical peptide profiles. Application of Decon2LS to deisotope different datasets obtained across different instruments yielded a high number of features that can be used to identify and quantify peptides in the biological sample. Conclusion: Decon2LS is an efficient software package for discovering and visualizing features in proteomics studies that require automated interpretation of mass spectra. Besides being easy to use, fast, and reliable, Decon2LS is also open-source, which allows developers in the proteomics and bioinformatics communities to reuse and refine the algorithms to meet individual needs.

A key challenge in DFN model parameterization is that parameters measured from cell tear-down experiments cannot be directly used in simulations, and parameter identification is required to accurately reflect real-world battery dynamics However, existing open-source DFN codes lack the capability to perform parameter identification and operate in open-loop mode. COBRAPRO addresses this gap by implementing a systematic parameterization pipeline to accurately determine parameters using battery current and voltage data. Concepts from structural and practical identifiability are utilized to determine parameters that can be fixed to their experimental values and parameters that are suitable for optimization. In the parameter identification process, particle swarm optimization is used to minimize the error between experimental data and simulation results. Additionally, COBRAPRO incorporates a robust method to determine consistent initial conditions and utilizes a fast numerical solver for improved performance. We demonstrate COBRAPRO's parameter identification framework on reference performance test data obtained from LG INR21700-M50T cells. The parameterized model is validated against driving cycle data, showing good agreement between the experimental and simulation results.}, DOI = {10.1149/1945-7111/ad7292}, Article-Number = {090522}, ISSN = {0013-4651}, EISSN = {1945-7111}, ORCID-Numbers = {Ha, Sung Yeon (Sara)/0009-0005-9878-3537 Onori, Simona/0000-0002-6556-2608}, Unique-ID = {WOS:001320997600001}, } @article{ WOS:000253858100006, Author = {Clavero, Javier and Formenti, Eulalia and Prieto, Toni}, Title = {Free software at the UPC libraries}, Journal = {PROFESIONAL DE LA INFORMACION}, Year = {2008}, Volume = {17}, Number = {1}, Pages = {56-63}, Month = {JAN-FEB}, Abstract = {We reviewed projects and outcomes in the implementation and use of free software in the Technical University of Catalonia (UPC) libraries.

Developers often follow popular developers and projects for learning, technical selection, and collaboration. Thus, identifying popular developers and projects is very meaningful. In this paper, we propose a multiplex bipartite network ranking model, M-BiRank, to co-rank developers and projects using multiple developer-project interactions. Firstly, multiple developer-project interactions such as commit, issue, and watch are extracted and a multiplex developer-project bipartite network is constructed. Secondly, a random layer is selected from this multiplex bipartite network and initial ranking scores are calculated for developers and projects using BiRank. Finally, initial ranking scores diffuse to other layers and mutual reinforcement is taken into consideration to iteratively calculate ranking scores of developers and projects in different layers. Experiments on real-world GitHub dataset show that M-BiRank outperforms degree centrality, traditional single layer ranking methods, and multiplex ranking method.}, DOI = {10.1186/s13638-020-01820-3}, Article-Number = {215}, ISSN = {1687-1472}, EISSN = {1687-1499}, ResearcherID-Numbers = {ZHANG, YIWEN/AAM-4652-2021 }, ORCID-Numbers = {Yan, Dengcheng/0000-0003-1417-5269}, Unique-ID = {WOS:000588293000002}, } @inproceedings{ WOS:000291090300032, Author = {Magrassi, Paolo}, Editor = {Tsui, E}, Title = {Free and Open-Source Software is not an Emerging Property but Rather the Result of Studied Design}, Booktitle = {PROCEEDINGS OF THE 7TH INTERNATIONAL CONFERENCE ON INTELLECTUAL CAPITAL, KNOWLEDGE MANAGEMENT AND ORGANISATIONAL LEARNING}, Year = {2010}, Pages = {285-292}, Note = {7th International Conference on Intellectual Capital, Knowledge Management and Organisational Learning, Hong Kong Polytechn Univ, Hong Kong, PEOPLES R CHINA, NOV 11-12, 2010}, Abstract = {Free and open source software (FOSS) is considered by many, along with Wikipedia, the proof of an ongoing paradigm shift from hierarchically-managed and market-driven production of knowledge to heterarchical, collaborative and commons-based production styles. In such perspective, it has become common place to refer to FOSS as a manifestation of collective intelligence where deliverables and artefacts emerge by virtue of mere cooperation, with no need for supervising leadership. We show that this assumption is based on limited understanding of the software development process, and may lead to wrong conclusions as to the potential of peer production. The development of a less than trivial piece of software, irrespective of whether it be FOSS or proprietary, is a complex cooperative effort requiring the participation of many (often thousands of) individuals. A subset of the participants always play the role of leading system and subsystem designers, determining architecture and functionality; the rest of the people work ``underneath{''} them in a logical, functional sense. While new and powerful forces, including FOSS, are clearly at work in the post-industrial, networked economy, the currently ingenuous stage of research in the field of collective intelligence and networked cooperation must give way to a deeper level of consciousness, which requires an understanding of the software development process.}, ISBN = {978-1-906638-84-9}, Unique-ID = {WOS:000291090300032}, } @inproceedings{ WOS:000850208000049, Author = {Truong, Kimberly and Miller, Courtney and Vasilescu, Bogdan and Kastner, Christian}, Book-Group-Author = {IEEE Comp Soc}, Title = {The Unsolvable Problem or the Unheard Answer?

Key examples of this include identification of ripening stages of fruit such as tomatoes and the determination of chlorophyll content as an indicator of plant health. While methods exist for determining these important phenotypes, they often require proprietary software or require coding knowledge to adapt existing code.ResultsWe provide a set of free and open-source Python scripts that, without any adaptation, are able to perform background correction and colour correction on images using a ColourChecker chart. Further scripts identify objects, use an object of known size to calibrate for size, and extract the average colour of objects in RGB, Lab, and YUV colour spaces. We use two examples to demonstrate the use of these scripts. We show the consistency of these scripts by imaging in four different lighting conditions, and then we use two examples to show how the scripts can be used. In the first example, we estimate the lycopene content in tomatoes (Solanum lycopersicum) var. Tiny Tim using fruit images and an exponential model to predict lycopene content. We demonstrate that three different cameras (a DSLR camera and two separate mobile phones) are all able to model lycopene content. The models that predict lycopene or chlorophyll need to be adjusted depending on the camera used. In the second example, we estimate the chlorophyll content of basil (Ocimum basilicum) using leaf images and an exponential model to predict chlorophyll content.ConclusionA fast, cheap, non-destructive, and inexpensive method is provided for the determination of the size and colour of plant materials using a rig consisting of a lightbox, camera, and colour checker card and using free and open-source scripts that run in Python 3.8.

We perform an in-depth analysis of build failures in CI environments. Our approach links repository commits to data of corresponding CI builds. Using data from 14 open-source Java projects, we first identify 14 common error categories. Besides test failures, which are by far the most common error category (up to >80\% per project), we also identify noisy build data, e.g., induced by transient Git interaction errors, or general infrastructure flakiness. Second, we analyze which factors impact the build results, taking into account general process and specific CI metrics. Our results indicate that process metrics have a significant impact on the build outcome in 8 of the 14 projects on average, but the strongest influencing factor across all projects is overall stability in the recent build history. For 10 projects, more than 50\% (up to 80\%) of all failed builds follow a previous build failure.

As there is currently no single diagnostic gold standard test, PCD is diagnosed by a combination of several methods comprising genetic testing and the examination of the ciliary structure and function. Among the approved diagnostic methods, only high-speed video microscopy (HSVM) allows to directly observe the ciliary motion and therefore, to directly assess ciliary function. In the present work, we present our recently developed freely available open-source software - termed ``Cilialyzer{''}, which has been specifically designed to support and facilitate the analysis of the mucociliary activity in respiratory epithelial cells captured by high-speed video microscopy.Methods: In its current state, the Cilialyzer software enables clinical PCD analysts to load, preprocess and replay recorded image sequences as well as videos with a feature-rich replaying module facilitating the commonly performed qualitative visual assessment of ciliary function (including the assessment of the ciliary beat pattern). The image processing methods made accessible through an intuitive user interface allow clinical specialists to comfortably compute the ciliary beating frequency (CBF), the activity map and the ``frequency correlation length{''} - an observable getting newly introduced. Furthermore, the Cilialyzer contains a simple-to-use particle tracking interface to determine the mucociliary transport speed.Results: Cilialyzer is fully written in the Python programming language and freely available under the terms of the MIT license. The proper functioning of the computational analysis methods constituting the Cilialyzer software is demonstrated by using simulated and representative sample data from clinical practice. Additionally, the software was used to analyze high-speed videos showing samples obtained from healthy controls and genetically confirmed PCD cases (DNAI1 and DNAH11 mutations) to show its clinical applicability.Conclusions: Cilialyzer serves as a useful clinical tool for PCD analysts and provides new quantitative information awaiting to be clinically evaluated using cohorts of PCD. As Cilialyzer is freely available under the terms of a permissive open-source license, it serves as a ground frame for further development of computational methods aiming at the quantification and automation of the analysis of mucociliary activity captured by HSVM.}, DOI = {10.1016/j.cmpb.2023.107744}, EarlyAccessDate = {AUG 2023}, Article-Number = {107744}, ISSN = {0169-2607}, EISSN = {1872-7565}, ResearcherID-Numbers = {Müller, Loretta/ABV-7343-2022 }, ORCID-Numbers = {Schneiter, Martin/0000-0003-4900-8807 Muller, Loretta/0000-0002-3145-1483}, Unique-ID = {WOS:001060851100001}, } @article{ WOS:000994043000006, Author = {Song, Kwang Yoon and Kim, Youn Su and Chang, In Hong}, Title = {Software reliability model for open-source software that considers the number of finite faults and dependent faults}, Journal = {MATHEMATICAL BIOSCIENCES AND ENGINEERING}, Year = {2023}, Volume = {20}, Number = {7}, Pages = {11785-11804}, Abstract = {Software has become a vital factor in the fourth industrial revolution. Owing to the increase in demand for software products in various fields (big data, artificial intelligence, the Internet of Things, etc.), the software industry has expanded more than ever before. Therefore, software reliability has become very important, and efforts are being made to increase it. One of these efforts is the development of software reliability models (SRMs). SRMs have been studied for a long time as a model that predicts software reliability by using the number of software faults. Software failures can occur for several reasons, including independent software faults such as code errors and software hangs, as well as dependent cases where code errors lead to other software faults. Recently, due to the diversity of software operating environments, software faults are more likely to occur in a dependent manner, and, for this reason, they are likely to increase rapidly from the beginning and progress slowly to the maximum number thereafter. In addition, many large companies have focused on open-source software (OSS) development, and OSS is being developed by many users. In this study, we propose a new SRM that considers the number of finite faults and dependent faults, and examine the goodness-of-fit of a new SRM and other existing non-homogeneous Poisson process models based on the OSS datasets. Through numerical examples, the proposed model demonstrated a significantly better goodness-of-fit when compared to other existing models, and it also exhibited better results on the newly proposed integrated criteria.}, DOI = {10.3934/mbe.2023524}, ISSN = {1547-1063}, EISSN = {1551-0018}, ResearcherID-Numbers = {Kim, Yong Won/AAA-2134-2022}, Unique-ID = {WOS:000994043000006}, } @article{ WOS:000625381700001, Author = {Belevich, Ilya and Jokitalo, Eija}, Title = {DeepMIB: User-friendly and open-source software for training of deep learning network for biological image segmentation}, Journal = {PLOS COMPUTATIONAL BIOLOGY}, Year = {2021}, Volume = {17}, Number = {3}, Month = {MAR}, Abstract = {We present DeepMIB, a new software package that is capable of training convolutional neural networks for segmentation of multidimensional microscopy datasets on any workstation.

Global optimization methods, which provide a robust methodology, and metaheuristics in particular have proven to be the most efficient methods for many applications. Despite their utility, there is a limited availability of metaheuristic tools. Results: We present MEIGO, an R and Matlab optimization toolbox (also available in Python via a wrapper of the R version), that implements metaheuristics capable of solving diverse problems arising in systems biology and bioinformatics. The toolbox includes the enhanced scatter search method (eSS) for continuous nonlinear programming (cNLP) and mixed-integer programming (MINLP) problems, and variable neighborhood search (VNS) for Integer Programming (IP) problems. Additionally, the R version includes BayesFit for parameter estimation by Bayesian inference. The eSS and VNS methods can be run on a single-thread or in parallel using a cooperative strategy. The code is supplied under GPLv3 and is available at http://www.iim.csic.es/similar to gingproc/meigo.html. Documentation and examples are included. The R package has been submitted to BioConductor. We evaluate MEIGO against optimization benchmarks, and illustrate its applicability to a series of case studies in bioinformatics and systems biology where it outperforms other state-of-the-art methods.

This paper examines the development of a web GIS application as part of an emission inventory system that produces maps and files with spatial allocated emissions in a grid format. The study is not confined in the maps produced but also presents the features and capabilities of a web application that can be used by every user even without any prior knowledge of the GIS field. The development of the application was based on open source software tools such as MapServer for the GIS functions, PostgreSQL and PostGIS for the data management and HTML, PHP and JavaScript as programming languages. In addition, background processes are used in an innovative manner to handle the time consuming and computational costly procedures of the application. Furthermore, a web map service was created to provide maps to other clients such as the Google Maps API v3 that is used as part of the user interface. The output of the application includes maps in vector and raster format, maps with temporal resolution on daily and hourly basis, grid files that can be used by air quality management systems and grid files consistent with the European Monitoring and Evaluation Programme Grid. Although the system was developed and validated for the Republic of Cyprus covering a remarkable wide range of pollutant and emissions sources, it can be easily customized for use in other countries or smaller areas, as long as geospatial and activity data are available.

A popular example of open innovation has been open source software (OSS). The key issues facing organizational decision makers considering OSS strategies is, how does the firm create value for the customer while simultaneously extracting value for itself? However, the adoption of OSS as part of an open innovation strategy is a recent phenomenon and many unanswered questions remain. Taking the viewpoint of seven IS/IT decision makers in European firms, this paper reveals how decision makers considered aspects of value creation, capture, and networking in making decisions on adopting open source software. The findings reveal that while decision makers look to open innovation for value creation and capture, there is still a desire to remain self reliant, resulting in collaborative design (of external innovations) rather than collaborative decision making with value network partners in relation to how such innovations would help create and capture value within firms.}, ISSN = {1571-5736}, ISBN = {978-0-387-87502-6}, Unique-ID = {WOS:000260450200013}, } @article{ WOS:000449138900007, Author = {Sbai, Nesrine and Lenarduzzi, Valentina and Taibi, Davide and Ben Sassi, Sihem and Ben Ghezala, Henda Hajjami}, Title = {Exploring information from OSS repositories and platforms to support OSS selection decisions}, Journal = {INFORMATION AND SOFTWARE TECHNOLOGY}, Year = {2018}, Volume = {104}, Pages = {104-108}, Month = {DEC}, Abstract = {Context: Individuals and organizations are increasingly adopting Open Source Software (OSS) for the benefits it provides.

Method: To reach this aim, we studied the processes and the information considered by the major OSS assessment models.

Finally, we characterized the maturity of the projects available on these three platforms. Results: Projects available on the three platforms are commonly old, stable, and mature ones. Moreover, thanks to the API provided, we were able to extract most of the information not commonly accessible from the main website.

On one hand, most FOSS systems are based on very fine-grained units of software deployment - called packages - which promote system evolution; on the other hand, FOSS systems are among the largest software systems known and require sophisticated static and dynamic conditions to be verified, in order to successfully deploy upgrades on users' machines. The slightest error in one of these conditions can turn a routine upgrade into a system administrator's nightmare. In this paper we introduce a model-based approach to support the upgrade of FOSS systems. The approach promotes the simulation of upgrades to predict failures before affecting the real system. Both fine-grained static aspects (e.g. configuration incoherences) and dynamic aspects (e.g. the execution of configuration scripts) are taken into account, improving over the state of the art of upgrade planners. The effectiveness of the approach is validated by instantiating the approach to widely-used FOSS distributions. (C) 2010 Elsevier B.V.

While nowadays new objects are mostly detected in larger sky surveys, several follow-up observations are usually needed for each object to improve the accuracy of orbit determination. In particular objects orbiting close to Earth, so called Near-Earth Objects (NEOs) are of special concern as a small but not negligible fraction of them can have a non-zero impact probability with Earth. Additionally, the observation of manmade space debris and tracking of satellites falls in the same class measurements. Telescopes for these follow-up observations are mainly in a aperture class between 1 m down to approximately 25 cm. These telescopes are often hosted by amateur observatories or dedicated companies like 6ROADS specialized on this type of observation. With upcoming new NEO search campaigns by very wide field of view telescopes, like the Vera C. Rubin Observatory, NASA's NEO surveyor space mission and ESA's Flyeye telescopes, the number of NEO discoveries will increase dramatically. This will require an increasing number of useful telescopes for follow-up observations at different geographical locations. While well-equipped amateur astronomers often host instruments which might be capable of creating useful measurements, both observation planning and scheduling, and also analysis are still a major challenge for many observers. In this work we present a fully robotic planning, scheduling and observation pipeline that extends the widely used open-source cross-platform software KStars/Ekos for Instrument Neutral Distributed Interface (INDI) devices. The method consists of algorithms which automatically select NEO candidates with priority according to ESA's Near-Earth Object Coordination Centre (NEOCC). It then analyses detectable objects (based on limiting magnitudes, geographical position, and time) with preliminary ephemeris from the Minor Planet Center (MPC). Optimal observing slots during the night are calculated and scheduled. Immediately before the measurement the accurate position of the minor body is recalculated and finally the images are taken. Besides the detailed description of all components, we will show a complete robotic hard- and software solution based on our methods.}, DOI = {10.3389/fspas.2022.895732}, Article-Number = {895732}, ISSN = {2296-987X}, ResearcherID-Numbers = {Santana-Ros, Toni/HOH-8322-2023 Reszelewski, Rafal/ACC-0496-2022 }, ORCID-Numbers = {Reszelewski, Rafal/0000-0002-2046-5521 Santana-Ros, Toni/0000-0002-0143-9440 Hoffmann, Tobias/0000-0003-4643-3664}, Unique-ID = {WOS:000870538400001}, } @article{ WOS:000718883900003, Author = {Nandi, Arnab and Virmani, Garima and Barve, Aatmika and Marathe, Swananda}, Title = {DBscorer: An Open-Source Software for Automated Accurate Analysis of Rodent Behavior in Forced Swim Test and Tail Suspension Test}, Journal = {ENEURO}, Year = {2021}, Volume = {8}, Number = {6}, Month = {NOV-DEC}, Abstract = {Forced swim test (FST) and tail suspension test (TST) are commonly used behavioral tests for screening antidepressant drugs with a high predictive validity. These tests have also proved useful to assess the non-motor symptoms in the animal models of movement disorders such as Parkinson's disease and Huntington's disease. Manual analysis of FST and TST is a time-consuming exercise and has large observer-to-observer variability. Automation of behavioral analysis alleviates these concerns, but there are no easy-to-use open-source tools for such analysis. Here, we describe the development of Depression Behavior Scorer (DBscorer), an open-source program installable on Windows, with an intuitive graphical user interface (GUI), that helps in accurate quantification of immobility behavior in FST and TST from video analysis. Several calibration options allow customization of various parameters to suit the experimental requirements. Apart from the readout of time spent immobile, DBscorer also provides additional data and graphics of immobility/mobility states across time revealing the evolution of behavioral despair over the duration of the test and allows the analysis of additional parameters. Such comprehensive analysis allows a more nuanced understanding of the expression of behavioral despair in FST and TST. We believe that DBscorer would make analysis of behavior in FST and TST unbiased, automated and rapid, and hence prove to be helpful to the wider neuroscience community.}, DOI = {10.1523/ENEURO.0305-21.2021}, Article-Number = {0305-21.2021}, EISSN = {2373-2822}, ORCID-Numbers = {Barve, Aatmika/0000-0003-2331-5825 Nandi, Arnab/0000-0001-6179-6805}, Unique-ID = {WOS:000718883900003}, } @inproceedings{ WOS:000387762800011, Author = {Fernandes, Sara and Barbosa, Luis Soares}, Editor = {Yuizono, T and Ogata, H and Hoppe, U and Vassileva, J}, Title = {Applying the 3C Model to FLOSS Communities}, Booktitle = {COLLABORATION AND TECHNOLOGY, CRIWG 2016}, Series = {Lecture Notes in Computer Science}, Year = {2016}, Volume = {9848}, Pages = {139-150}, Note = {22nd International Conference on Collaboration Technologies (CRIWG), Kanazawa, JAPAN, SEP 14-16, 2016}, Abstract = {How learning occurs within Free/LibreOpen Source (FLOSS) communities and what is the dynamics of such projects (e.g. the life cycle of such projects) are very relevant questions when considering the use of FLOSS projects in a formal education setting.

An intriguing question is whether such sustained participation in OSS projects yields economic benefits to the participants. Moreover, as participants engage in OSS projects, they take on different roles and activities in the community. This raises additional questions of whether different forms of participation in OSS communities are associated with different economic rewards and, if so, in which contexts. In this paper, we draw upon theories of signaling and job matching to hypothesize that participants who possess ``proof{''} of their skills in OSS projects are financially rewarded for their activities in the labor market. More specifically, we distinguish between participation in OSS communities that is associated with a signaling value for unobserved productivity characteristics and an additional value that accrues to participants whose OSS roles and activities match those in their paid employment. Following a cohort of OSS programmers over a six-year period, we empirically examine the wages and OSS performance of participants in three of the foremost OSS projects operating within the Apache Software Foundation. Controlling for individual characteristics and other wage-related factors, our findings reveal that credentials earned through a merit-based ranking system are associated with as much as an 18\% increase in wages. Moreover, we find that participants who have OSS project management responsibilities receive additional financial rewards if their professional job is in IT management. These findings suggest that rank within an OSS meritocracy is a credible and precise signal of participants' productive capacity and that participants' roles and activities in an OSS community have additional financial value when aligned with their paid employment.}, DOI = {10.1287/isre.2013.0474}, ISSN = {1047-7047}, EISSN = {1526-5536}, Unique-ID = {WOS:000324010300002}, } @article{ WOS:000988244400001, Author = {Han, Yisi and Wang, Zhendong and Feng, Yang and Zhao, Zhihong and Wang, Yi}, Title = {Cross-status communication and project outcomes in OSS development A language style matching perspective}, Journal = {EMPIRICAL SOFTWARE ENGINEERING}, Year = {2023}, Volume = {28}, Number = {3}, Month = {MAY}, Abstract = {Context The success of an open source software (OSS) project requires effective communication among its members. Given that OSS projects often have established social status systems, such communication may happen between individuals of different statuses, particularly, elite developers with project management privileges and ordinary project contributors. They communicate with each other onmany essential activities, e.g., bug fixing, code review, etc., thus having profound influences on project outcomes. Objectives We seek to develop an understanding of cross-status communication from a perspective of language stylematching among developers of different status, and its relationships with an OSS project's outcomes in terms of productivity and quality. Method We approach the above research objectives with the language stylematching (LSM) tool, which measures the similarities of cross-status communication inmultiple language style features. We first dynamically identify elite developers having project administration privileges for each sampled project. Then, we capture the cross-status communication between elite and non-elite developers; and calculate the LSM features of these two groups of individuals. The LSM variables, together with project outcomes, were used to fit regression models to analyze potential relationships between cross-status communication's language matching and project outcomes. Results Using over 275,000 collected conversations, our analyses yield rich insights into cross-status communication in open source development. First, our results reveal that the elite and non-elite developers exhibit quite similar linguistic patterns in using certain categories of words. Second, we explore the relationships between linguistic similarity in cross-status communication and project outcomes. The regression results are generally negative, indicating there might be very limited significant relationships between cross-status communication's language matching and project outcomes, with a few exceptions. Limitations The study has several limitations. First, it considers projects hosted on GitHub only. Second, to ensure data availability, our sample is drawn from top projects, thus not representing all projects. Third, we only consider a limited number of linguistic features, and indicators for project outcomes.

The aim of this study was to compare the gliding capacities of different flosses with major differences in structure and experimental behavior in vivo. Methods: In a clinical, single-blind, crossover study of 27 subjects, the forces necessary for passing all 14 proximal contacts between the first premolars were measured using 2 polytetrafluoroethylene (PTFE)-based flosses, 2 nylon-based flosses, and 1 nylon-based tape. The flosses were fixed in a special holder with strain gauges, which allowed registration of the maximum forces at insertion into and removal from the interdental area. Results: In most contacts, the PTFE flosses needed less force compared to the nylon flosses. The range between the flosses was higher in the mandible compared to the maxilla and increased from the mesially located contacts to the more distally located contacts. The nylon tape required higher forces at insertion for all maxillary contacts. All other flosses proved to be equivalent at these contacts. Conclusions: PTFE flosses are superior to nylon flosses in terms of passing stronger proximal contacts in both directions. Due to gliding differences between different types of floss, the selection of a floss has the potential of compensating intra- and interindividual variation in contact strengths.}, DOI = {10.1902/jop.2001.72.5.672}, ISSN = {0022-3492}, ResearcherID-Numbers = {Doerfer, Christof/E-4041-2010}, Unique-ID = {WOS:000168908600014}, } @article{ WOS:000354030700004, Author = {Di Ruscio, Davide and Pelliccione, Patrizio}, Title = {A model-driven approach to detect faults in FOSS systems}, Journal = {JOURNAL OF SOFTWARE-EVOLUTION AND PROCESS}, Year = {2015}, Volume = {27}, Number = {4}, Pages = {294-318}, Month = {APR}, Abstract = {Free and Open-Source Software (FOSS) Linux distributions are among the most complex modern software systems. They are made of thousands of components (software packages) evolving rapidly without centralized coordination. The upgrade of FOSS systems is managed by meta-installers, which solve package dependencies and conflicts and lead the system to a new system configuration by installing or removing packages. Current tools are able to predict a very limited set of upgrade faults before deployment, and this leaves a wide range of faults unpredicted. In this paper, we focus on faults that remain unpredicted, for example, missing packages, packages that are not properly installed, and missing services, with the aim of providing a solution for them. Specifically, in this paper, we propose a model-driven approach and supporting tools to prevent specific classes of system configuration faults before performing the real upgrade. Once the system configuration is represented as a model, the configuration model is evaluated by means of queries, each devoted to discover a specific class of faults. The approach is intrinsically extensible so that user communities can add new queries when new classes of faults are identified. The approach has been validated by executing the fault detector on configuration models in which faults have been intentionally injected and by analyzing produced results.

Many students have taken part in OSS projects as well as developers. At the University of Lincoln, under the Undergraduate Research Opportunities Scheme (UROS), undergraduate student researchers have the chance to work over the summer embedded within an existing research centre on a UROS project. Here two such projects within the Centre for Research in Open Source Software (CROSS) are described: Collaborative Development for the XO Laptop (CODEX) and Software Modularity in Open Source Software (SoMOSS).

Existing literature on user innovation and usability is reviewed, after which usability innovation is empirically explored in OSS development. The interpretive ease study shows that usability innovations emerge and evolve in OSS development. They emerge after a user recognizes a need, after which she invents a fix to meet the need, thereafter needing a developer to realize the fix in the OSS. Afterwards, the user experiments with the solution and may provide feedback, which again may lead to the developer adjusting the OSS accordingly. The process is characterized as a collaborative negotiation process among the users and developers. The results also reveal that the usability innovations may be need, opportunity or creativity based, and connected to improving efficiency, effectiveness or satisfaction.

Some others have investigated knowledge management among open-source-software (OSS) developers and discussed factors influencing knowledge transfer within development teams (e.g. Joshi and Sarker, 2006). In the domain of open source software (OSS) communities, more companies are now attempting to establish relationships to benefit from these potential value-creating communities; and project managers could in fact target different goals within software development teams including knowledge transfer within and between teams. We step forward to distinguish knowledge transfer within groups as opposed to knowledge transfer between groups; where relevant projects are bundled into separate strongly intra-connected groups. In knowledge management literature there is a trade-off between sparse network structures (Burt, 2000, 2002) versus dense network structures (Walker et al., 1997; Coleman, 1988). It is argued that the former facilitates the diffusion and generation of ideas among groups, while the latter affects the implementation of idea within each dense group. To our best knowledge, there has been no study to investigate the relationship between dense and sparse network structures. We propose that knowledge transfer within dense groups has a positive influence on knowledge transfer between sparse groups, in that intragroup density, group size, developers centrality and betweenness could impact intergroup coupling. To prove our hypothesis, we use a complex network of open source software (OSS) as the domain of interest, where developers represent nodes and two developers contributing to a project task represent a network tie. Developers contributing to tasks in groups other than their own can explore novel ideas via sharing knowledge, whereas developers contributing to tasks inside groups exploit ideas to improve those projects. We investigate the idea both analytically and empirically within 4 months, 8 months and 1 year lagged time, and finally show that intragroup density has a positive whereas developers' centrality has a negative influence on intergroup coupling.}, DOI = {10.1016/j.ijinfomgt.2017.09.004}, ISSN = {0268-4012}, EISSN = {1873-4707}, ResearcherID-Numbers = {Behfar, Stefan/O-6836-2019 Burger-Helmchen, Thierry/B-6360-2018}, ORCID-Numbers = {Burger-Helmchen, Thierry/0000-0001-8866-1919}, Unique-ID = {WOS:000416954500017}, } @article{ WOS:001180979300003, Author = {Neuhaus, Leonhard and Croquette, Michael and Metzdorff, Remi and Chua, Sheon and Jacquet, Pierre-Edouard and Journeaux, Alexandre and Heidmann, Antoine and Briant, Tristan and Jacqmin, Thibaut and Cohadon, Pierre-Francois and Deleglise, Samuel}, Title = {Python Red Pitaya Lockbox (PyRPL): An open source software package for digital feedback control in quantum optics experiments}, Journal = {REVIEW OF SCIENTIFIC INSTRUMENTS}, Year = {2024}, Volume = {95}, Number = {3}, Month = {MAR 1}, Abstract = {We present the Python Red Pitaya Lockbox (PyRPL), an open source software package that allows the implementation of automatic digital feedback controllers for quantum optics experiments on commercially available, affordable Field-Programmable Gate Array (FPGA) boards. Our software implements the digital generation of various types of error signals, from an analog input through the application of loop filters of high complexity and real-time gain adjustment for multiple analog output signals, including different algorithms for resonance search, lock acquisition sequences, and in-loop gain optimization. Furthermore, all necessary diagnostic instruments, such as an oscilloscope, a network analyzer, and a spectrum analyzer, are integrated into our software. Apart from providing a quickly scalable, automatic feedback controller, the lock performance that can be achieved by using PyRPL with imperfect equipment, such as piezoelectric transducers and noisy amplifiers, is better than the one achievable with standard analog controllers due to the higher complexity of implementable filters and possibilities of nonlinear operations in the FPGA. This drastically reduces the cost of added complexity when introducing additional feedback loops to an experiment. The open-source character also distinguishes PyRPL from commercial solutions, as it allows users to customize functionalities at various levels, ranging from the easy integration of PyRPL-based feedback controllers into existing setups to the modification of the FPGA functionality.

However, OSS has only found its way into the public arena within the past decade due to some major projects gaining significant market share from commercial developers such as Microsoft. Research in the area of OSS has become more extensive in recent years and has examined areas such as motivation of programmers as well as the benefits of OSS. However, literature focusing on the actual implementation of OSS is more limited with only Fitzgerald and Kenny {[}(2004). Developing an information infrastructure with Open Source Software.

This sector has a history of resource wastage and underperforming information systems. The underpinning issues of motivation and benefits to organisations will be addressed along with the difficulties that the UK Government faces in adopting an OSS strategy. Section 2 examines the existing literature in the area and explores why OSS should be adopted and implemented by the public sector in the UK. Section 3 considers the research approach taken and the results obtained from considering the implementation of OSS in eight government organisations. Section 4 concludes with a discussion and some implications for those organisations in the public sector who might wish to take this approach.

In most ecological studies, only a single similarity cutoff value is used for sequence identification. This is not sufficient since the most commonly used DNA markers are known to vary widely in terms of inter- and intraspecific variability. We address this problem by presenting a new tool, dnabarcoder, to predict local similarity cutoffs and measure the resolving powers of a biomarker for sequence identification for different clades of fungi. It was shown that the predicted similarity cutoffs varied significantly between the clades of a recently released ITS DNA barcode data set from the CBS culture collection of the Westerdijk Fungal Biodiversity Institute. When classifying a large public fungal ITS data set-the UNITE database-against the barcode data set, the local similarity cutoffs assigned fewer sequences than the traditional cutoffs used in metabarcoding studies. However, the obtained accuracy and precision were significantly improved. Our study showed that it might be better to extract the ITS region from the ITS barcodes to optimize taxonomic assignment accuracy. Furthermore, 15.3, 25.6, and 26.3\% of the fungal species of the barcode data set were indistinguishable by full-length ITS, ITS1, and ITS2, respectively. Except for these indistinguishable species, the resolving powers of full-length ITS, ITS1, and ITS2 sequences were similar at the species level. Nevertheless, the complete ITS region had a better resolving power at higher taxonomic levels.}, DOI = {10.1111/1755-0998.13651}, EarlyAccessDate = {JUN 2022}, ISSN = {1755-098X}, EISSN = {1755-0998}, ResearcherID-Numbers = {Nilsson, R./A-6062-2009 Vũ, Dương/KCZ-0177-2024 }, ORCID-Numbers = {Verkley, Gerard/0000-0001-6575-2439 Vu, Duong/0000-0001-7960-2765}, Unique-ID = {WOS:000813362800001}, } @article{ WOS:000325847000010, Author = {Realini, Eugenio and Reguzzoni, Mirko}, Title = {goGPS: open source software for enhancing the accuracy of low-cost receivers by single-frequency relative kinematic positioning}, Journal = {MEASUREMENT SCIENCE AND TECHNOLOGY}, Year = {2013}, Volume = {24}, Number = {11}, Month = {NOV}, Abstract = {goGPS is a free and open source satellite positioning software package aiming to provide a collaborative platform for research and teaching purposes. It was first published in 2009 and since then several related projects are on-going. Its objective is the investigation of strategies for enhancing the accuracy of low-cost single-frequency GPS receivers, mainly by relative positioning with respect to a base station and by a tailored extended Kalman filter working directly on code and phase observations. In this paper, the positioning algorithms implemented in goGPS are presented, emphasizing the modularity of the software design; two specific strategies to support the navigation with low-cost receivers are also proposed and discussed, namely an empirical observation weighting function calibrated on the receiver signal-to-noise ratio and the inclusion of height information from a digital terrain model as an additional observation in the Kalman filter. The former is crucial when working with high-sensitivity receivers, while the latter can significantly improve the positioning in the vertical direction. The overall goGPS positioning accuracy is assessed by comparison with a dual-frequency receiver and with the positioning computed by a standard low-cost receiver. The benefits of the calibrated weighting function and the digital terrain model are investigated by an experiment in a dense urban environment. It comes out that the use of goGPS and low-cost receivers leads to results comparable with those obtained by higher level receivers; goGPS has good performances also in a dense urban environment, where its additional features play an important role.}, DOI = {10.1088/0957-0233/24/11/115010}, Article-Number = {115010}, ISSN = {0957-0233}, EISSN = {1361-6501}, ResearcherID-Numbers = {Realini, Eugenio/U-9116-2019 Reguzzoni, Mirko/K-9001-2018}, ORCID-Numbers = {Realini, Eugenio/0000-0003-4119-6989 Reguzzoni, Mirko/0000-0002-4027-9347}, Unique-ID = {WOS:000325847000010}, } @article{ WOS:000486999200028, Author = {Mayur, Manik and DeCaluwe, Steven C. and Kee, Benjamin L. and Bessler, Wolfgang G.}, Title = {Modeling and simulation of the thermodynamics of lithium-ion battery intercalation materials in the open-source software Cantera}, Journal = {ELECTROCHIMICA ACTA}, Year = {2019}, Volume = {323}, Month = {NOV 10}, Abstract = {Modeling and simulation play a key role in analyzing the complex electrochemical behavior of lithiumion batteries.

The productivity of such development teams, i.e., how their size is related to the produced output, is an important consideration for project and schedule management as well as for cost estimation. The majority of studies in empirical software engineering suggest that - due to coordination overhead - teams of collaborating developers become less productive as they grow in size. This phenomenon is commonly paraphrased as Brooks' law of software project management, which states that ``adding manpower to a software project makes it later{''}. Outside software engineering, the non-additive scaling of productivity in teams is often referred to as the Ringelmann effect, which is studied extensively in social psychology and organizational theory. Conversely, a recent study suggested that in Open Source Software (OSS) projects, the productivity of developers increases as the team grows in size. Attributing it to collective synergetic effects, this surprising finding was linked to the Aristotelian quote that ``the whole is more than the sum of its parts{''}. Using a data set of 58 OSS projects with more than 580,000 commits contributed by more than 30,000 developers, in this article we provide a large-scale analysis of the relation between size and productivity of software development teams. Our findings confirm the negative relation between team size and productivity previously suggested by empirical software engineering research, thus providing quantitative evidence for the presence of a strong Ringelmann effect. Using fine-grained data on the association between developers and source code files, we investigate possible explanations for the observed relations between team size and productivity. In particular, we take a network perspective on developer-code associations in software development teams and show that the magnitude of the decrease in productivity is likely to be related to the growth dynamics of co-editing networks which can be interpreted as a first-order approximation of coordination requirements.}, DOI = {10.1007/s10664-015-9406-4}, ISSN = {1382-3256}, EISSN = {1573-7616}, ResearcherID-Numbers = {Schweitzer, Frank/B-2127-2012 Scholtes, Ingo/A-8251-2012}, ORCID-Numbers = {Scholtes, Ingo/0000-0003-2253-0216}, Unique-ID = {WOS:000373349700011}, } @article{ WOS:000248090700004, Author = {Benoit-Barne, Chantal}, Title = {Socio-technical deliberation about free and open source software:: Accounting for the status of artifacts in public life}, Journal = {QUARTERLY JOURNAL OF SPEECH}, Year = {2007}, Volume = {93}, Number = {2}, Pages = {211-235}, Month = {MAY}, Abstract = {This essay investigates the rhetorical practices of socio-technical deliberation about free and open source (FIOS) software, providing support for the idea that a public sphere is a socio-technical ensemble that is discursive and fluid, yet tangible and organized because it is enacted by both humans and non-humans. In keeping with the empirical shift manifest in recent public sphere scholarship and Bruno Latour's idea that socio-technical deliberation is characterized by the inscription of non-humans, I describe the rhetorical manners in which volunteer citizens define and mobilize a mundane artifact-a web site- in a deliberation over the value of FIOS technologies for their government-funded project. Through inscription of the web site as a rhetorical resource and as the embodiment of their disposition toward computer technologies, the volunteers formed and expressed competing understandings of the role of FIOS technologies in sustaining a public sphere. I argue that these competing views are consequential, for they link technical artifacts and political agents in practice, by way of aspirations, obligations, and forms of authority. Furthermore, by claiming a form of agency for technologies in the public sphere, the proponents of F10S technologies are inviting scholars of the public sphere to question the status assigned to technical artifacts in their investigations and theories of the public sphere.}, DOI = {10.1080/00335630701426751}, ISSN = {0033-5630}, EISSN = {1479-5779}, Unique-ID = {WOS:000248090700004}, } @article{ WOS:000399859400007, Author = {Savelyev, Alexander}, Title = {Legal aspects of ownership in modified open source software and its impact on Russian software import substitution policy}, Journal = {COMPUTER LAW \& SECURITY REVIEW}, Year = {2017}, Volume = {33}, Number = {2}, Pages = {193-210}, Month = {APR}, Abstract = {In my previous publication, I tried to show how personal data legislation might be used for achieving the purposes of national sovereignty(1). In this paper, I will demonstrate how open source software may be used for achieving similar purposes. However, the interplay between local copyright law, public procurement law and open source community norms creates many issues relating to the legal status and ownership in modified software, based on open source. This is especially so in the case of so-called copyleft open source licenses, where a collision occurs between copyright, as an absolute right enforceable against the world, and the copyleft provisions of license agreements, which may be treated as ``rights in personam{''} enforceable only against the licensee. The exclusive right to derivative software as an independent object of copyright, may come into conflict with restrictions inherited from incoming copyleft licenses. This paper provides an overview and analysis of such problems faced by Russian software developers, attempting to comply with Russian import substitution provisions, by using open source components. Although it is based on Russian law, it may be applicable to other jurisdictions, since general aspects of copyright law and its interaction with private international law and contract law drive it. The paper concludes that the developer of software, containing code licensed under GEL or other copyleft provisions, receives full exclusive right to the derivative software and can commercialize it as he sees appropriate, subject only to possible claims of breach of contract rather than copyright infringement. This opens wide perspectives for using open source components regardless of the type of license used as bricks for building a de-globalized economy and society based on principles of information sovereignty.

For example, the size and shape of activated sludge flocs can indicate the conditions at the microscale, and also directly affect how well the sludge settles in a clarifier. Particle size and shape are both misleadingly `simple' measurements. Many subtle issues, often unaddressed in informal protocols, can arise when sampling, imaging, and analyzing particles. Sampling methods may be biased or not provide enough statistical power. The samples themselves may be poorly preserved or undergo alteration during immobilization. Images may not be of sufficient quality; overlapping particles, depth of field, magnification level, and various noise can all produce poor results. Poorly specified analysis can introduce bias, such as that produced by manual image thresholding and segmentation. Affordability and throughput are desirable alongside reproducibility. An affordable, high throughput method can enable more frequent particle measurement, producing many images containing thousands of particles. A method that uses inexpensive reagents, a common dissecting microscope, and freely-available open source analysis software allows repeatable, accessible, reproducible, and partially-automated experimental results. Further, the product of such a method can be well-formatted, well-defined, and easily understood by data analysis software, easing both within-lab analyses and data sharing between labs.

In the geomorphologic survey, different landforms have been identified in the area, including structural, anthropogenic, fluvial, karst, and slope forms. In particular, the majority of the slope forms are complex (from topple to rotational slides and falls), but there are also minor forms like debris flows and mudslides.

This is due to the high maintenance effort, time, and resources needed to effectively address issues during software maintenance (maintenance activities). Mismanagement of these efforts can lead to the degradation of software maintainability. Understanding the assessment of the related software processes can help sustain or improve maintainability during these maintenance activities. Recent studies have shown that current software process assessments are expensive, generic, and complex, especially for smaller organizations. In this paper, we investigate an alternative software process assessment approach performed by analyzing fine-grained processes (micro processes) of maintenance activities. This approach assesses maintenance efforts based on micro processes in relation to their impact on source code. The approach derives maintenance effort from the complexity and duration of micro processes and uses proposed metrics based on program slicing to measure change impact. In this paper, we investigate an alternative software process assessment approach by analysing fine-grained processes (micro processes) of maintenance activities. At statistically significant levels, results suggest that the level of the maintenance efforts correlates with its impact on source code.

The advantages of crowdsourcing include a higher volume of requirements reflecting a more comprehensive array of use cases and a more engaged and committed user base. Researchers cite the inability of project teams to effectively manage an increasing volume of system requirements as a possible drawback. This paper analyzes a data set consisting of project management artifacts from 562 open-source software (OSS) projects to determine how OSS project performance varies as the share of crowdsourced requirements increases using six measures of effectiveness: requirement close-out time, requirement response time, average comment activity, the average number of requirements per crowd member, the average retention time for crowd members, and the total volume of requirements. Additionally, the models measure how the impact of increasing the share of crowdsourced requirements changes with stakeholder network structure. The analysis shows that stakeholder network structure impacts OSS performance outcomes and that the effect changes with the share of crowdsourced requirements. OSS projects with more concentrated stakeholder networks perform the best. The results indicate that requirements crowdsourcing faces diminishing marginal returns. OSS projects that crowdsource more than 70\% of their requirements benefit more from implementing processes to organize and prioritize existing requirements than from incentivizing the crowd to generate additional requirements. Analysis in the paper also suggests that OSS projects could benefit from employing CrowdRE techniques and assigning dedicated community managers to more effectively channel input from the crowd.}, DOI = {10.1007/s00766-021-00353-5}, EarlyAccessDate = {MAY 2021}, ISSN = {0947-3602}, EISSN = {1432-010X}, Unique-ID = {WOS:000651340000001}, } @article{ WOS:000640542700004, Author = {Khan, Beenish and Mufti, Muhammad Rafiq and Habib, Asad and Afzal, Humaira and Zia, Mohammad Abdul Moiz and Almas, Afshan and Hussain, Shahid and Ahmad, Bashir}, Title = {Evolution of Influential Developer?s Communities in OSS and its Impact on Quality}, Journal = {INTELLIGENT AUTOMATION AND SOFT COMPUTING}, Year = {2021}, Volume = {28}, Number = {2}, Pages = {337-352}, Abstract = {The high turnover of developers in the Open-Source Software (OSS) systems is due to the lack of restriction on a developer?s involvement and contributions.

Model predictive control (MPC) has been shown to be a successful control strategy generally and as well as for managing urban drainage specifically. This research describes and demonstrates the implementation of MPC for urban drainage systems using open source software (Python and The United States Environmental Protection Agency (EPA) Storm Water Management Model (SWMM5). The system was demonstrated using a simplified use case in which an actively-controlled outlet of a detention pond is simulated. The control of the pond's outlet influences the flood risk of a downstream node. For each step in the SWMM5 model, a series of policies for controlling the outlet are evaluated. The best policy is then selected using an evolutionary algorithm. The policies are evaluated against an objective function that penalizes primarily flooding and secondarily deviation of the detention pond level from a target level. Freely available Python libraries provide the key functionality for the MPC workflow: step-by-step running of the SWMM5 simulation, evolutionary algorithm implementation, and leveraging parallel computing. For perspective, the MPC results were compared to results from a rule-based approach and a scenario with no active control. The MPC approach produced a control policy that largely eliminated flooding (unlike the scenario with no active control) and maintained the detention pond's water level closer to a target level (unlike the rule-based approach).}, DOI = {10.1007/978-3-319-99867-1\_170}, ISSN = {1865-3529}, EISSN = {1865-3537}, ISBN = {978-3-319-99867-1; 978-3-319-99866-4}, ResearcherID-Numbers = {Morsy, Mohamed/AFB-3219-2022 Goodall, Jonathan/B-3663-2009 }, ORCID-Numbers = {Morsy, Mohamed/0000-0001-9217-4822 Goodall, Jonathan/0000-0002-1112-4522 Sadler, Jeffrey/0000-0001-8776-4844}, Unique-ID = {WOS:000482068800170}, } @inproceedings{ WOS:000398534300038, Author = {Alves, Daniel Domingos and Cagnin, Maria Istela and Barroso Paiva, Debora Maria}, Editor = {Ezzatti, P and Delgado, A}, Title = {Accessibility in Development of Free Software Projects}, Booktitle = {PROCEEDINGS OF THE 2014 XL LATIN AMERICAN COMPUTING CONFERENCE (CLEI)}, Series = {Proceedings of the Latin American Computing Conference}, Year = {2014}, Note = {40th Latin American Computing Conference (CLEI), Univ Republica, Fac Ingn, Montevideo, URUGUAY, SEP 15-19, 2014}, Organization = {Univ Montevideo; Univ De La Empresa; Univ Catolica Uruguay; Univ Ort Uruguay}, Abstract = {In recent years the use of free software has been considered in private enterprise, government agencies and end users.

Small opaque chambers can be used to measure leaf, stem and soil respiration. Larger transparent chambers can be used to measure net ecosystem exchange of CO2, and small jars often serve this purpose for laboratory incubations of soil and plant material. We developed an Android application (app), called Flux Puppy, to facilitate chamber-based flux measurements in the field and laboratory. The app is designed to run on an inexpensive handheld Android device, such as a tablet or phone, and it has a graphical user interface that communicates with a LI-COR LI-820 and LI-830 (CO2) or LI-840 and LI-850 (CO2/H2O) infrared gas analyzer. The app logs concentrations of CO2 and H2O, cell temperature and pressure at 1 Hz, displays the output graphically, and calculates the linear regression slope, R-squared, and standard error of the CO2 time series. A metadata screen allows users to enter operator, site, and plot information, as well as take a photograph using the Android device's built-in camera, and log measurement location using the device GPS. Additionally, there is a notes field, which can be revised after the measurements are taken. Data files (the 1 s raw data, photograph, and metadata including statistics calculated from the raw data) are then transmitted off the device through file sharing options (Gmail, Outlook, Google Drive, Dropbox etc.). Because Flux Puppy code is open-source (available on GitHub) and the flux measurement system we describe is relatively inexpensive and straightforward to assemble, it should be of broad interest to the carbon cycling community.}, DOI = {10.1016/j.agrformet.2019.04.012}, ISSN = {0168-1923}, EISSN = {1873-2240}, ResearcherID-Numbers = {Seyednasrollah, Bijan/N-2006-2019 Richardson, Andrew/F-5691-2011 Carbone, Mariah/H-7389-2012}, ORCID-Numbers = {Richardson, Andrew/0000-0002-0148-6714 Rademacher, Tim/0000-0002-0627-6564 Carbone, Mariah/0000-0002-7832-7009}, Unique-ID = {WOS:000471356600001}, } @article{ WOS:000437868600003, Author = {McInerney, Paul-Brian and Andersen, Kirsten}, Title = {Networks of innovation: tracing the structures of flows among not-for-profit open source software foundations, philanthropies and intermediaries, 2004-06}, Journal = {VOLUNTARY SECTOR REVIEW}, Year = {2014}, Volume = {5}, Number = {1}, Pages = {47-73}, Month = {MAR}, Abstract = {Foundations are said to spark and facilitate innovation in the non-profit sector.

These formal standards are needed in the telecommunications market to achieve functional interoperability. The standardization process takes years, and then a vendor still needs to implement the resulting standard in a product. This prevents service providers (SPs) who are willing to venture into new domains from doing so at a fast pace. With the development of software-defined networking (SDN) and network function virtualization (NFV), opensource technology is emerging as a new option in the telecommunications market. In contrast to SDOs, open-source software (OSS) communities create a product that may implicitly define a de-facto standard based on market consensus. Therefore, SPs are drawn to OSS, but they face technical, procedural, legal, and cultural challenges due to their lack of experience with open software development. The question therefore arises, how the interaction between OSS communities, SDOs, and industry fora (IF) can be organized to tackle these challenges. This article examines the evolving roles of OSS communities, IF, and SDOs, and places them in an NFV/SDN context. It sketches the differences between these roles and provides guidelines on how the interaction between them can turn into a mutually beneficial relationship that balances the conflicting goals of timely development on the one hand and technical excellence, openness, and fairness on the other, to reach their common goal of creating flexible and efficient telecommunications networks.}, DOI = {10.1109/MCOM.2016.7432171}, ISSN = {0163-6804}, EISSN = {1558-1896}, ResearcherID-Numbers = {Verbrugge, Sofie/GQY-4760-2022 Pickavet, Mario/E-9530-2019 }, ORCID-Numbers = {Pickavet, Mario/0000-0001-5817-7886 Colle, Didier/0000-0002-1428-0301 Tavernier, Wouter/0000-0003-4408-6523}, Unique-ID = {WOS:000375041200008}, } @article{ WOS:000852253900001, Author = {Gupta, Neel and Mishra, Brijes and Crandall, Dustin M.}, Title = {A New Workflow of X-ray CT Image Processing and Data Analysis of Structural Features in Rock Using Open-Source Software}, Journal = {MINING METALLURGY \& EXPLORATION}, Year = {2022}, Volume = {39}, Number = {5, SI}, Pages = {2011-2024}, Month = {OCT}, Abstract = {X-ray computed tomography (CT) images of rock specimens often contain artifacts which must be corrected before scientific analyses are performed.

To understand how these firms try to harness the work of these communities, I use the empirical data to derive a 22 matrix of different approaches.

Various thematic maps such as lithology/hydrogeology, soil, land-cover/use, slope, lineament density, drainage density and rainfall distribution were integrated in QGIS software. Vector input layers were rasterized and resampled using QGIS wrap projection function to make sure that the grid cells are of the same size. Reclassification using SAGA and GRASS reclass algorithms in QGIS was carried out to realign the factor classes in a consistent scale, and reclassification to a scale of 1 to 5 was carried out to harmonize the results. The study identified a number of potential areas for groundwater recharge, groundwater exploration, groundwater development and potential areas for artificial groundwater recharge. Potential groundwater recharge zones for the Singida semi-arid fractured aquifer are restricted to areas with high lineament density, cultivated areas, grassland and flat to gentle slopes. The potential of groundwater recharge is also observed in areas with low drainage density. The delineated zones provide a good understanding of the potential recharge zones, which are a starting point for recharge zone protection. This blended approach can be utilized for carrying out suitability analysis using the weighted overlay analysis approach. Areas designated good and very good are recommended for artificial recharging structures as an alternative technique for enhancing groundwater recharge through rainwater harvesting. This will help to augment groundwater storage in this semi-arid environment.}, DOI = {10.3390/hydrology7020028}, Article-Number = {28}, EISSN = {2306-5338}, ResearcherID-Numbers = {Mussa, Kassim/KIG-2603-2024 }, ORCID-Numbers = {Ramadhani Mussa, Kassim/0000-0002-1671-2411}, Unique-ID = {WOS:000551260500006}, } @inproceedings{ WOS:000258398700031, Author = {Balieiro, Marco A. and de Sousa Junior, Samuel F. and de Souza, Cleidson R.

However, such tasks require extensive project experience of long term contributors (LTCs). Aim: We measure, understand, and predict how the newcomers' involvement and environment in the issue tracking system (ITS) affect their odds of becoming an LTC. Method: ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. We also reproduced the results on new data provided by Mozilla. Results: We constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants. Newcomers who are able to get at least one issue reported in the first month to be fixed, doubled their odds of becoming an LTC. The macro-climate with high project popularity and the micro-climate with low attention from peers reduced the odds. The precision of LTC prediction was 38 times higher than for a random predictor. We were able to reproduce the results with new Mozilla data without losing the significance or predictive power of the previously published model. We encountered unexpected changes in some attributes and suggest ways to make analysis of ITS data more reproducible. Conclusions: The findings suggest the importance of initial behaviors and experiences of new participants and outline empirically-based approaches to help the communities with the recruitment of contributors for long-term participation and to help the participants contribute more effectively.

The primary aim of this investigation was to ascertain whether the combination of off-the-shelf hardware components and open-source software yielded vital-sign measurements (specifically heart rate and respiratory rate) comparable to those obtained from more expensive, commercially endorsed medical devices. Conducted as a prospective, single-center study, the research involved the assessment of fifteen participants for three minutes in four distinct positions, supine, seated, standing, and walking in place.

The evaluation of the OSS software packages to choose the best one is a challenging task owing to (a) multiple evaluation criteria, (b) criteria importance, and (c) data variation; thus, it is considered a sophisticated multi-criteria decision making (MCDM) problem; moreover, the multi-perspective usability evaluation framework for OSS selection lacks in the current literature. Hence, this study proposes a novel multi-perspective usability evaluation framework for the selection of OSS based on the multi-criteria analysis. Integration of best-worst method (BWM) and VIKOR MCDM techniques has been used for weighting and ranking OSS alternatives. BWM is utilized for weighting of evaluation criteria, whereas VIKOR is applied to rank OSS-LMS alternatives. Individual and group decision-making contexts, and the internal and external groups aggregation were used to demonstrate the efficiency of the proposed framework. A well-organized algorithmic procedure is presented in detail, and a case study was examined to illustrate the validity and feasibility of the proposed framework. The results demonstrated that BWM and VIKOR integration works effectively to solve the OSS software package benchmarking/selection problems. Furthermore, the ranks of OSS software packages obtained from the VIKOR internal and external group decision making were similar; the best OSS-LMS based on the two ways was `Moodle' software package. Among the scores of groups in the objective validation, significant differences were identified; this indicated that the ranking results of internal and external VIKOR group decision making were valid, which pointed to the validation of the framework.}, DOI = {10.1142/S0219622021500139}, ISSN = {0219-6220}, EISSN = {1793-6845}, ResearcherID-Numbers = {Dawood, Kareem/AAB-5709-2021 zaidan, bilal/AAJ-7841-2021 Zaidan, A./F-7289-2010 }, ORCID-Numbers = {zaidan, bilal/0000-0001-7412-8267 Dawood, Kareem Abbas/0000-0002-7024-0961}, Unique-ID = {WOS:000925645400007}, } @inproceedings{ WOS:000341299300255, Author = {Dou Changyong and Guo Huadong and Han Chunming and Liu Ming}, Editor = {Guo, H}, Title = {An Open Source Software and Web-GIS Based Platform for Airborne SAR Remote Sensing Data Management, Distribution and Sharing}, Booktitle = {35TH INTERNATIONAL SYMPOSIUM ON REMOTE SENSING OF ENVIRONMENT (ISRSE35)}, Series = {IOP Conference Series-Earth and Environmental Science}, Year = {2014}, Volume = {17}, Note = {35th International Symposium on Remote Sensing of Environment (ISRSE35), Inst Remote Sensing \& Digital Earth, Beijing, PEOPLES R CHINA, APR 22-26, 2013}, Organization = {Chinese Acad Sci; Int Ctr Remote Sensing Environm; Int Soc Photogrammetry \& Remote Sensing; Grp Earth Observat; Int Soc Digital Earth; Chinese Acad Sci; Natl Remote Sensing Ctr China; LDE; REIS; LIESMARS; State Key Laboratory of Remote Sensing Science}, Abstract = {With more and more Earth observation data available to the community, how to manage and sharing these valuable remote sensing datasets is becoming an urgent issue to be solved.

It can provide extra-wide-lane (EWL), wide-lane (WL), and narrow-lane (NL) UPDs for GPS, GLONASS, Galileo and BDS (GREC) satellites for precise point positioning (PPP) ambiguity resolution (AR) in a multi-GNSS and multi-frequency environment.

We develop a formal model where both volunteers (agents setting their agendas freely) and firm's employees (agents whose agenda is mostly set by their employer) participate in the creation of a common artifact. In this framework, we discuss how firms can influence the architecture of the emerging product to assure fast and performant development and a desirable distribution of innovative labor within the project team. We find that closing the project only to employees implies high speed and performance if employees are given autonomy in certain dimensions and are directed in others. In this case, however, we observe a trade-off in terms of ideal core-periphery division of labor on one side and development speed and performance on the other side. At the opposite extreme, creating a volunteer-only project can ease the trade-off but assures positive results only if the firm is able to set up an entry mechanism that ``surgically{''} selects volunteers with specific preferences.

In particular, there has been a surge in deep learning and computer vision techniques to analyse digital images. Common practice in this area is to use image pre-processing and augmentation to prevent bias and overfitting, creating a more robust deep learning model. This generally requires consultation of documentation for multiple coding libraries, as well as trial and error to ensure that the techniques used on the images are appropriate. Herein we introduce HistoClean; a user-friendly, graphical user interface that brings together multiple image processing modules into one easy to use toolkit. HistoClean is an application that aims to help bridge the knowledge gap between pathologists, biomedical scientists and computer scientists by providing transparent image augmentation and pre-processing techniques which can be applied without prior coding knowledge. In this study, we utilise HistoClean to pre-process images for a simple convolutional neural network used to detect stromal maturity, improving the accuracy of the model at a tile, region of interest, and patient level. This study demonstrates how HistoClean can be used to improve a standard deep learning workflow via classical image augmentation and pre-processing techniques, even with a relatively simple convolutional neural network architecture.

The approach offers a way to capture motion adapted from the film industry in which markers placed on the skin of the face can be tracked with a pattern-matching algorithm. The method records and postprocesses raw facial movement data (coordinates per frame) of distinctly placed markers and is intended for use in facial expression research (e.g., microexpressions) in laboratory settings. Due to the explicit use of specifically placed, artificial markers, the procedure offers the simultaneous measurement of several emotionally relevant markers in a (psychometrically) objective and artifact-free way, even for facial regions without natural landmarks (e.g., the cheeks). In addition, the proposed procedure is fully based on open-source software and is transparent at every step of data processing. Two worked examples demonstrate the practicability of the proposed procedure: In Study 1(N=39), the participants were instructed to show the emotions happiness, sadness, disgust, and anger, and in Study 2 (N=113), they were asked to present both a neutral face and the emotions happiness, disgust, and fear. Study 2 involved the simultaneous tracking of 14 markers for approximately 12 min per participant with a time resolution of 33 ms. The measured facial movements corresponded closely to the assumptions of established measurement instruments (EMFACS, FACSAID, Friesen \& Ekman, 1983; Ekman \& Hager, 2002).

Methods which deliver composite data reflecting the mean values of biomarkers from cell populations risk losing subpopulation dynamics that reflect the heterogeneity of the studied biological system.

These assays potentially generate large numbers of images of fluorescent biomarkers, which enabled by accompanying proprietary software packages, allows for multi-parametric measurements per cell. However, the relatively high capital costs and overspecialization of many of these devices have prevented their accessibility to many investigators. Described here is a universally applicable workflow for the quantification of multiple fluorescent marker intensities from specific subcellular regions of individual cells suitable for use with images from most fluorescent microscopes. Key to this workflow is the implementation of the freely available Cell Profiler software(1) to distinguish individual cells in these images, segment them into defined subcellular regions and deliver fluorescence marker intensity values specific to these regions. The extraction of individual cell intensity values from image data is the central purpose of this workflow and will be illustrated with the analysis of control data from a siRNA screen for G1 checkpoint regulators in adherent human cells.

The software implements a model to explain the allelic peak height on a continuous scale in order to carry out weight-of-evidence calculations for profiles which could be from a mixture of contributors. Through a properly parameterized model we are able to do inference on mixture proportions, the peak height properties, stutter proportion and degradation. In addition, EuroForMix includes models for allele drop-out, allele drop-in and sub-population structure. EuroForMix supports two inference approaches for likelihood ratio calculations. The first approach uses maximum likelihood estimation of the unknown parameters. The second approach is Bayesian based which requires prior distributions to be specified for the parameters involved. The user may specify any number of known and unknown contributors in the model, however we find that there is a practical computing time limit which restricts the model to a maximum of four unknown contributors. EuroForMix is the first freely open source, continuous model (accommodating peak height, stutter, drop-in, drop-out, population substructure and degradation), to be reported in the literature. It therefore serves an important purpose to act as an unrestricted platform to compare different solutions that are available. The implementation of the continuous model used in the software showed close to identical results to the R-package DNAmixtures, which requires a HUGIN Expert license to be used. An additional feature in EuroForMix is the ability for the user to adapt the Bayesian inference framework by incorporating their own prior information. (C) 2015 Elsevier Ireland Ltd.

Education studies have also analysed the importance of these communities in spreading and sharing knowledge and educational culture has looked to these organizational forms for inspiration. At the same time, the link between these experiences and the development of pedagogical models emerging from cognitive sciences, systemic theory and the new forms of constructivism, which have generated a fruitful theory/practice circle, has been reinforced. The aim of this paper is to analyse the particular type of organizational, communicative and productive context of Open Communities: Free Software Communities, to understand how they work, their efficacy and to show their close link with dynamics and relations of an educational, formative and didactic type. Learning communities can still learn strategies of communication, organization and socialization from these communities, as well as the value of motivation and the importance of freedom and circulation of knowledge in order to build up efficient communities. We can also gain the understanding that the success of these communities depends on the fact that they are educational communities, therefore education studies can convey values, models and a culture of sharing to other sectors as well, such as the one taken into consideration: Free Software Communities. The study has been conducted with a research methodology of the phenomenological type thanks to a theoretical study and observation of different free software communities, visiting websites, chats, wiki pages, forums and other channels of discussion and collaboration.}, ISSN = {2340-1117}, ISBN = {978-84-697-3777-4}, Unique-ID = {WOS:000493048103075}, } @inproceedings{ WOS:000408982800046, Author = {Shahzad, Sara and Hussain, Ammara and Nazir, Shah}, Book-Group-Author = {IEEE}, Title = {A Clone Management Framework to Improve Code Quality of FOSS Projects}, Booktitle = {PROCEEDINGS OF 2017 INTERNATIONAL CONFERENCE ON COMMUNICATION, COMPUTING AND DIGITAL SYSTEMS (C-CODE)}, Year = {2017}, Pages = {253-258}, Note = {International Conference on Communication, Computing and Digital Systems (C-CODE), Bahria Univ, Islamabad, PAKISTAN, MAR 08-09, 2017}, Organization = {Higher Educ Commiss; IEEE; Pakistan Software Export Board; UBL; Bank Alfalah Islam; NAFA; Optcl; EES INT; ERN; ABN; British Canadian Int Educ Ltd; Univ York}, Abstract = {The emergence of Free/Open Source Software (FOSS) development model as a widely adopted paradigm in the software development industry in the recent few years has developed the interest of researchers towards the code quality of FOSS projects. Code clones are introduced in the software system by the adoption of common code reuse practices by FOSS developers. This has led the clone research community to observe the effects of code clones on the code quality of FOSS projects. Although code clones are not always harmful but they might become critical to large scale and evolving software systems such as FOSS projects. Research in this paper reveals the importance and need for improving code quality of FOSS projects by implementing an effective clone management system integrated in the FOSS development environment. This paper proposes a clone management framework that ensures effective clone evolution tracking and visualization in FOSS projects. This framework will appear as a baseline to initiate the efforts towards improving code quality by the implementation of a versatile clone management system for FOSS development.}, ISBN = {978-1-5090-4448-1}, ResearcherID-Numbers = {Nazir, Shah/D-2020-2015}, Unique-ID = {WOS:000408982800046}, } @inproceedings{ WOS:000349106400013, Author = {Fezzardi, Pietro and Lipinski, Maciej and Rubini, Alessandro and Colosimo, Aurelio}, Book-Group-Author = {IEEE}, Title = {PPSi - A Free Software PTP Implementation}, Booktitle = {2014 IEEE INTERNATIONAL SYMPOSIUM ON PRECISION CLOCK SYNCHRONIZATION FOR MEASUREMENT, CONTROL AND COMMUNICATION (ISPCS)}, Series = {IEEE International Symposium on Precision Clock Synchronization for Meaurement Control and Communication}, Year = {2014}, Pages = {71+}, Note = {8th IEEE International Symposium on Precision Clock Synchronization for Measurement, Control, and Communication (ISPCS), Austin, TX, SEP 22-26, 2014}, Organization = {IEEE; IEEE Instrumentat \& Measurement Soc}, Abstract = {This paper describes a new open source implementation of the Precision Time Protocol (PTP) {[}1] called PTP Ported To Silicon (PPSi) {[}2].

To bridge the gap, we perform an exploratory study of OpenStack: a large OSS ecosystem with intense commercial participation. We quantify companies' contributions via the developers that they provide and the commits made by those developers. We find that companies made far more contributions than volunteers and the distribution of the contributions made by different companies is also highly unbalanced. We observe eight unique contribution models based on companies' commercial objectives and characterize each model according to three dimensions: contribution intensity, extent, and focus. Companies providing full cloud solutions tend to make both intensive (more than other companies) and extensive (involving a wider variety of projects) contributions. Usage-oriented companies make extensive but less intense contributions. Companies driven by particular business needs focus their contributions on the specific projects addressing these needs. Minor contributors include community players (e.g., the Linux Foundation) and research groups. A model relating the number of volunteers to the diversity of contribution shows a strong positive association between them.}, DOI = {10.1109/TSE.2019.2946156}, ISSN = {0098-5589}, EISSN = {1939-3520}, ResearcherID-Numbers = {Jin, Zhi/E-1288-2013 Mockus, Audris/AEY-3361-2022 }, ORCID-Numbers = {Jin, Zhi/0000-0003-1087-226X Mockus, Audris/0000-0002-7987-7598 Zhou, Minghui/0000-0001-6324-3964}, Unique-ID = {WOS:000707441900012}, } @article{ WOS:000303561800004, Author = {Schoonmaker, Sara}, Title = {HACKING THE GLOBAL Constructing markets and commons through free software}, Journal = {INFORMATION COMMUNICATION \& SOCIETY}, Year = {2012}, Volume = {15}, Number = {4, SI}, Pages = {502-518}, Abstract = {This paper explores software's pivotal role in the power dynamics of contemporary capitalism.

However, these files often do not follow a standard structure, can be too large, and miss barriers commonly found by newcomers.

We manually classified a sample of files according to a model of onboarding barriers from the literature, trained a machine learning classifier that automatically predicts the categories of each paragraph (precision: 0.655, recall: 0.662), and surveyed developers to investigate their perspective of the predictions' adequacy (75\% of the predictions were considered adequate). We found that CONTRIBUTING files typically do not cover the barriers newcomers face (52\% of the analyzed projects missed at least 3 out of the 6 barriers faced by newcomers; 84\% missed at least 2). Our analysis also revealed that information about choosing a task and talking with the community, two of the most recurrent barriers newcomers face, are neglected in more than 75\% of the projects. We made available our classifier as an online service that analyzes the content of a given CONTRIBUTING file.

Architectural decay is, potentially, a major issue in Free/Libre/Open Source Software (FLOSS) projects, since developers sporadically joining FLOSS projects do not always have a clear understanding of the underlying architecture, and may break the overall conceptual structure by several small changes to the code base. This paper investigates whether the structure of a FLOSS system and its decay can also be influenced by the repository in which it is retained: specifically, two FLOSS repositories are studied to understand whether the complexity of the software structure in the sampled projects is comparable, or one repository hosts more complex systems than the other It is also studied whether the effort to counteract this complexity is dependent on the repository, and the governance it gives to the hosted projects. The results of the paper are two-fold: on one side, it is shown that the repository hosting larger and more active projects presents more complex structures. On the other side, these larger and more complex systems benefit from more anti-regressive work to reduce this complexity.}, DOI = {10.1109/CSMR.2009.37}, ISSN = {1944-2793}, ISBN = {978-0-7695-3589-0}, ResearcherID-Numbers = {Capiluppi, Andrea/AGO-2961-2022 }, ORCID-Numbers = {Capiluppi, Andrea/0000-0001-9469-6050}, Unique-ID = {WOS:000266729900017}, } @inproceedings{ WOS:000393155100010, Author = {Viseur, Robert}, Editor = {Cardoso, J and Ferguson, D and Munoz, VM and Helfert, M}, Title = {A FLOSS License-selection Methodology for Cloud Computing Projects}, Booktitle = {PROCEEDINGS OF THE 6TH INTERNATIONAL CONFERENCE ON CLOUD COMPUTING AND SERVICES SCIENCE, VOL 1 (CLOSER)}, Year = {2016}, Pages = {129-136}, Note = {6th International Conference on Cloud Computing and Services Science (CLOSER), Rome, ITALY, APR 23-25, 2016}, Abstract = {Cloud computing and open source are two disruptive innovations. Both deeply modify the way the computer resources are made available and monetized. They evolve between competition (e.g. open source software for desktop versus SaaS applications) and complementarity (e.g. cloud solutions based on open source components or cloud applications published under open source license). PaaSage is an open source integrated platform to support both design and deployment of cloud applications. The PaaSage consortium decided to publish the source code as open source. It needed a process for the open source license selection. Open source licensing scheme born before the development of cloud computing and evolved with the creation of new open source licenses suitable for SaaS applications. The license is a part of project governance and strongly influences the life of the project. In the context of the PaaSage European project, the issue of the open source license selection for cloud computing software has been addressed.

The second section studies the common choices of licenses in cloud computing projects. The third section proposes a FLOSS license-selection process for cloud computing project following five steps: (1) inventoring software components, (2) selecting open source license, (3) approving license selection (vote), (4) spreading practical details and (5) monitoring source code.

This poses serious implications to the assessment and continued management of plant species cover, for example in the control of invasive plant species. Morphological analysis of digital imagery has, to date, been primarily applied in the classification of landscape features. Our novel application of morphological image analysis provides an objective method for detection and accurate cover assessment of an invasive alien plant species (IAS), giving reduced measurement errors when compared to visual estimation. Importantly, this method is entirely based on free software. Guidos Toolbox is a collection of generic raster image processing routines, including Morphological Spatial Pattern Analysis (MSPA), which classifies and quantifies features according to shape. MSPA was employed in this study to detect and quantify cover of invasive Petasites pyrenaicus (Winter heliotrope) in digital images of 1 m x 1 m plots. Its efficacy was compared to that of two other methods- GIS Digitisation (used as an accurate baseline) and Visual Estimation (standard method). We tested the limit of MSPA usability on images of varying complexity, i.e. ``simple{''}, intermediate{''} or ``complex{''}, depending on presence/absence of other vascular plant species and the species richness of plot. Our results show good agreement between all three methods. MSPA measurement of P. pyrenaicus cover was most closely aligned with the GIS Digitisation (concordance correlation coefficients of 0.966). Visual Estimation was less closely aligned with GIS Digitisation (concordance correlation coefficients of 0.888). However, image complexity resulted in differing levels of agreement; with the closest agreement being achieved between MSPA and GIS Digitisation when used on images of lower and higher complexity. MSPA consistently provides higher accuracy and precision for P. pyrenaicus cover measurement than the standard Visual Estimation method. Our methodology is applicable to a range of focal vegetation species, both herbaceous and graminoid. Future application of MSPA for larger-scale surveying and monitoring via remote sensing is discussed, potentially reducing resource demands and increasing cover measurement consistency and accuracy. We recommend this method forms part of vegetation management toolkits for not only environmental managers, but for anyone concerned with plant cover assessment, from agricultural systems to sustainable resource use.}, DOI = {10.1016/j.jenvman.2020.110519}, Article-Number = {110519}, ISSN = {0301-4797}, EISSN = {1095-8630}, ResearcherID-Numbers = {Coughlan, Neil/AAT-1760-2020 }, ORCID-Numbers = {Coughlan, Neil/0000-0001-5597-3238 Lucy, Frances/0000-0002-4785-2724}, Unique-ID = {WOS:000531083400038}, } @article{ WOS:000480826800010, Author = {Abbott, Adam S. and Turney, Justin M. and Zhang, Boyi and Smith, Daniel G.

However, numerous health-care-specific OSS applications exist, the adoption of OSS health information technology (HIT) applications is not widespread in the United States. Purpose: This disconnect between the availability of promising software and low adoption raises the basic question: If OSS HIT is so advantageous, why are more health care organizations not using it? Methodology: We interviewed the chief information officer, or equivalent position, at 17 not-for-profit and public hospitals across the United States. Through targeted recruitment, our sample included nine hospitals using OSS HIT and eight hospitals not using OSS HIT. The open-ended interview questions were guided by domains included in the fit-viability theory, an organizational-level innovation adoption framework, and those suggested by a review of the literature. Transcripts were analyzed using an inductive and comparative approach, which involved an open coding for relevant themes. Findings: Interviews described the state of OSS use in hospitals. Specifically, general OSS applications were widely used by IT professionals. In addition, hospitals using OSS HIT still relied heavily on vendor support. In terms of why decisions arose to use OSS HIT, several hospitals using OSS HIT noted the cost advantages. In contrast, hospitals avoiding OSS HIT were clear, OSS as a class did not fit with clinical work and posed too much risk. Practice Implications: Perceptions of OSS HIT ranged from enthusiastic embracement to resigned adoption, to refusal, to abandonment. Some organizations were achieving success with their OSS HIT choices, but they still relied on vendors for significant support. The decision to adopt OSS HIT was not uniform but contingent upon views of the risk posed by the technology, economic factors, and the hospital's existing capabilities.}, DOI = {10.1097/HMR.0b013e318276f9ed}, ISSN = {0361-6274}, EISSN = {1550-5030}, ORCID-Numbers = {Vest, Joshua/0000-0002-7226-9688}, Unique-ID = {WOS:000324754700010}, } @article{ WOS:000269170900002, Author = {Suhanic, West and Crandall, Ian and Pennefather, Peter}, Title = {An informatics model for guiding assembly of telemicrobiology workstations for malaria collaborative diagnostics using commodity products and open-source software}, Journal = {MALARIA JOURNAL}, Year = {2009}, Volume = {8}, Month = {JUL 17}, Abstract = {Background: Deficits in clinical microbiology infrastructure exacerbate global infectious disease burdens. This paper examines how commodity computation, communication, and measurement products combined with open-source analysis and communication applications can be incorporated into laboratory medicine microbiology protocols. Those commodity components are all now sourceable globally. An informatics model is presented for guiding the use of low-cost commodity components and free software in the assembly of clinically useful and usable telemicrobiology workstations. Methods: The model incorporates two general principles: 1) collaborative diagnostics, where free and open communication and networking applications are used to link distributed collaborators for reciprocal assistance in organizing and interpreting digital diagnostic data; and 2) commodity engineering, which leverages globally available consumer electronics and open-source informatics applications, to build generic open systems that measure needed information in ways substantially equivalent to more complex proprietary systems. Routine microscopic examination of Giemsa and fluorescently stained blood smears for diagnosing malaria is used as an example to validate the model. Results: The model is used as a constraint-based guide for the design, assembly, and testing of a functioning, open, and commoditized telemicroscopy system that supports distributed acquisition, exploration, analysis, interpretation, and reporting of digital microscopy images of stained malarial blood smears while also supporting remote diagnostic tracking, quality assessment and diagnostic process development. Conclusion: The open telemicroscopy workstation design and use-process described here can address clinical microbiology infrastructure deficits in an economically sound and sustainable manner. It can boost capacity to deal with comprehensive measurement of disease and care outcomes in individuals and groups in a distributed and collaborative fashion. The workstation enables local control over the creation and use of diagnostic data, while allowing for remote collaborative support of diagnostic data interpretation and tracking. It can enable global pooling of malaria disease information and the development of open, participatory, and adaptable laboratory medicine practices. The informatic model highlights how the larger issue of access to generic commoditized measurement, information processing, and communication technology in both high-and low-income countries can enable diagnostic services that are much less expensive, but substantially equivalent to those currently in use in high-income countries.}, DOI = {10.1186/1475-2875-8-164}, Article-Number = {164}, EISSN = {1475-2875}, Unique-ID = {WOS:000269170900002}, } @article{ WOS:000264389200026, Author = {Vosskuehler, Adrian and Nordmieeer, Volkhard and Kuchrvke, Lars and Jacobs, Artmr M.}, Title = {OGAMA (Open Gaze and Mouse Analyzer): Open-source software designed to analyze eye and mouse movements in slideshow study designs}, Journal = {BEHAVIOR RESEARCH METHODS}, Year = {2008}, Volume = {40}, Number = {4}, Pages = {1150-1162}, Month = {NOV}, Abstract = {In the present article, a new software is introduced that allows the recording and analyzing of eye- and mouse-tracking data from slideshow-based experiments in parallel.

A series of hypotheses about how distributed innovation (independent variables) influences knowledge sharing (mediating variable) and then affects the performance of OSS projects (dependent variable) are tested and approved. On the one side, we argue that developers will actively affect knowledge sharing in terms of participative motivation, social network and organisational culture. On the other hand, users may also affect the knowledge sharing when considering innovation willingness and capacity. It is interesting to find that social network is the most important factor in Chinese cases.

Celeris is an open source software which needs minimum preparation to run on a Windows machine. The software solves the extended Boussinesq equations using a hybrid finite volume finite difference method and supports moving shoreline boundaries. The simulation and visualization are performed on the GPU using Direct3D libraries, which enables the software to run faster than real-time. Celeris provides a first-of-its-kind interactive modeling platform for coastal wave applications and it supports simultaneous visualization with both photorealistic and colormapped rendering capabilities. We validate our software through comparison with three standard benchmarks for non-breaking and breaking waves. Program summary Program title: Celeris Program Files doi: http://dx.doi.org/10.17632/5djwvf5x5k.1 Licensing provisions: GNU General Public License 3 (GPL) Programming language: C++, HLSL Nature of problem: Boussinesq-type models provide the research-level accuracy needed for modeling wave propagation in coastal zones. However the current models, both commercial and open source, do not provide means for real-time computation, nor provide model interactivity and concurrent visualization. In order to achieve a real-time simulation speed in current parallelized models, dozens to hundreds of CPU cores are needed. Celeris is an interactive software which provides faster than real-time simulation and visualization speed on an average user laptop. The novelty of this software is its interactive environment, which allows the user to modify the model and field parameters as the model is running, and to see the effect of these changes immediately. Solution method: A hybrid finite volume-finite difference scheme is used to solve the extended Boussinesq equations. The solver is parallelized using shader programming with Direct3D libraries. Visualization is also performed with the same libraries. (C) 2017 Elsevier B.V.

We have developed a new generic software package for the solution of inverse problems implementing the Ensemble Smoother with Multiple Data Assimilation (genES-MDA).

Its aim is to facilitate the management and configuration of the ES-MDA through several programming tools that help in the preparation of the different steps of ES-MDA. genES-MDA has a flexible workflow that can be easily adapted for the implementation of different variants of the ensemble Kalman filter and for the solution of generic inverse problems. This paper presents a description of the package and some application examples. genES-MDA has been tested in three synthetic case studies: the solution of the reverse flow routing for the estimation of the inflow hydrograph to a river reach using observed water levels and a calibrated forward model of the river system, the identification of a hydraulic conductivity field using piezometric observations and a known forward flow model, and the estimation of the release history of a contaminant spill in an aquifer from measured concentration data and a known flow and transport model. The results of all these tests have demonstrated the flexibility of genES-MDA and its capabilities to efficiently solve different types of inverse problems.}, DOI = {10.1016/j.cageo.2022.105210}, EarlyAccessDate = {AUG 2022}, Article-Number = {105210}, ISSN = {0098-3004}, EISSN = {1873-7803}, ResearcherID-Numbers = {Todaro, Valeria/AFS-5006-2022 Tanda, Maria/M-1761-2014 Gomez-Hernandez, J.

Motile cilia move fluid flow or propel cells, while also fulfill sensory functions. Primary cilia are immotile and act as a cellular antenna, translating environmental cues into cellular responses. Ciliary dysfunction leads to severe diseases, commonly termed ciliopathies. The molecular details underlying ciliopathies and ciliary function are, however, not well understood. Since cilia are small subcellular compartments, imaging-based approaches have been used to study them. However, tools to comprehensively analyze images are lacking. Automatic analysis approaches require commercial software and are limited to 2D analysis and only a few parameters. The widely used manual analysis approaches are time consuming, user-biased, and difficult to compare. Here, we present CiliaQ, a package of open-source, freely available, and easy-to-use ImageJ plugins. CiliaQ allows high-throughput analysis of 2D and 3D, static or time-lapse images from fluorescence microscopy of cilia in cell culture or tissues, and outputs a comprehensive list of parameters for ciliary morphology, length, bending, orientation, and fluorescence intensity, making it broadly applicable.

It is particularly challenging in Free and Open Source Software (FOSS) ecosystems, in which hundreds of loosely connected developers and their projects are coordinated to release software to a schedule. To better understand this process and its challenges, we analyzed over two and half years of communication in the GNOME ecosystem and studied developers' interactions. Through a case study, we cataloged communication channels, determined the main channel from which we categorized high level communication and coordination activities spanning five releases, and triangulated our results by interviewing ten key developers. We found that a release schedule, influence (instead of direct control), and diversity are the main factors that positively impact the release process in the GNOME ecosystem. We report a set of lessons learned that encapsulates our understanding of how the Release Management process function in a FOSS ecosystem, we learned that: (1) ensure that the release team follows the main communication channels used by developers, (2) provide a common place for coordination for an ecosystem, (3) consider including both good technical and social skills in a release team, (4) aim for a diverse release team, (5) based on lack of power, lobbying and consensus based management must be followed, (6) help the release team in the coordination process with a well defined schedule, and (7) release team work is different from regular software work.

However, it requires frequent and costly testing and may introduce compatibility issues. Consequently, developers often choose to backport security patches to the vulnerable versions instead. Manual backporting is time-consuming, especially for large OSS such as the Linux kernel. Therefore, automating this process is urgently needed to save considerable time. Existing automated approaches for backporting patches involve either automatic patch generation or automatic patch migration. However, these methods are often ineffective and error-prone since they failed to locate the precise patch locations or generate the correct patch, operating only on the syntactic level. In this paper, we propose a patch type-sensitive approach to automatically backport OSS security patches, guided by the patch type and patch semantics. Specifically, our approach identifies patch locations with the aid of program dependency graph-based matching at the semantic level. It further applies fine-grained patch migration and fine-tuning based on patch types. We have implemented our approach in a tool named TSBPORT and evaluated it on a large-scale dataset consisting of 1,815 pairs of real-world security patches for the Linux kernel. The evaluation results show that TSBPORT successfully backported 1,589 (87.59\%) patches, out of which 587 (32.34\%) could not be backported by any state-of-the-art approaches, significantly outperforming state-of-the-art approaches. In addition, experiments also show that TSBPORT can be generalized to backport patches in other OSS projects with a success rate of 88.18\%.}, DOI = {10.1145/3576915.3623188}, ISBN = {979-8-4007-0050-7}, ResearcherID-Numbers = {Xiao, Yang/JGM-3278-2023 Sun, Chengyi/ABT-6276-2022 }, ORCID-Numbers = {Xiao, Yang/0009-0005-8009-2252 Yang, Su/0000-0002-1832-5829 Zhang, Yuqing/0000-0001-8306-7195}, Unique-ID = {WOS:001124987202025}, } @article{ WOS:000969502900001, Author = {Botha, Tarryn Lee and Bamuza-Pemu, Emomotimi and Roopnarain, Ashira and Ncube, Zibusiso and De Nysschen, Gert and Ndaba, Busiswa and Mokgalaka, Ntebogeng and Bello-Akinosho, Maryam and Adeleke, Rasheed and Mushwana, Akani and van der Laan, Michael and Mphahlele, Phedisho and Vilakazi, Fanelesibonge and Jaca, Penny and Ubomba-Jaswa, Eunice}, Title = {Development of a GIS-based knowledge hub for contaminants of emerging concern in South African water resources using open-source software: Lessons learnt}, Journal = {HELIYON}, Year = {2023}, Volume = {9}, Number = {1}, Month = {JAN}, Abstract = {With population growth and dwindling freshwater sources, protecting such sources has come to the forefront of water resource management.

Fiber characterization and potential market identification are critical to its development. The most promising commercial use for milkweed floss is as a loose fill for jackets and comforters. The purpose of this research was to evaluate milkweed floss as an insulative fill material and to compare its performance to other insulators. Seven identical jackets were constructed using different fill materials matched on a per unit weight basis. The insulation (clo) values for the jackets were measured using a standing, heated manikin in an environmental chamber. Thickness (loft), compression, resiliency, and hand were also measured. Several performance characteristics were evaluated before and after cleaning. The results show that milkweed floss blended with down has insulative properties similar to down. Down is superior to milkweed floss in loftiness and compressibility, which influence product performance, but the properties of milkweed floss can be enhanced by blending with down.}, DOI = {10.1177/004051759106100403}, ISSN = {0040-5175}, Unique-ID = {WOS:A1991FF00700003}, } @inproceedings{ WOS:000532562900006, Author = {Schranz, Thomas and Schindler, Christian and Mueller, Matthias and Slany, Wolfgang}, Editor = {Sentilles, S and Boehm, B and Trubiani, C and Koziolek, A}, Title = {Contributors' Impact on a FOSS Project's Quality}, Booktitle = {PROCEEDINGS OF THE 2ND ACM SIGSOFT INTERNATIONAL WORKSHOP ON SOFTWARE QUALITIES AND THEIR DEPENDENCIES (SQUADE' 19)}, Year = {2019}, Pages = {35-38}, Note = {2nd ACM SIGSOFT International Workshop on Software Qualities and Their Dependencies (SQUADE), Tallinn, ESTONIA, AUG 26, 2019}, Organization = {Assoc Comp Machinery; ACM SIGSOFT}, Abstract = {Engaging contributors in a Free Open Source Software (FOSS) project can be challenging.

Shifting focus can have impact on the software quality and productivity, and is thus an important topic of investigation. In this paper, we study focus shifting patterns (FSPs) of developers by comparing trace data from a dozen open source software (OSS) projects of their longitudinal commit activities and file dependencies from the projects call graphs. Using information theoretic measures of network structure, we find that fairly complex focus-shifting patterns emerge, and FSPs in the same project are more similar to each other. We show that developers tend to shift focus along with, rather than away from, software dependency links described by the call graphs. This tendency becomes weaker as either the interval between successive commits, or the organizational distance between committed files (i.e. directory distance), gets larger. Interestingly, this tendency appears stronger with more productive developers. We hope our study will initiate interest in further understanding of FSPs, which can ultimately help to (1) improve current recommender systems to predict the next focus of developers, and (2) provide insight into better call graph design, so as to facilitate developers' work.}, DOI = {10.1145/2635868.2635914}, ISBN = {978-1-4503-3056-5}, ResearcherID-Numbers = {Barr, Earl T.

The outliers were removed by the OCSVM (one-class support vector machine) model, and the unique mapping relationship between the strain value and the deformation variables (three directions of x-, y-, and z-axis) at each point was completed by a neural-network model. The test results show that the maximum error of the measuring point in the direction of the three coordinate axes: the x-axis is 2.01\%, the y-axis is 29.49\%, and the z-axis is 15.52\%. The error of the coordinates in the y and z directions was large, and the deformation variables were small, the reconstructed shape had good consistency with the deformation state of the specimen under the existing test environment.

Therefore, organizations are increasingly becoming OSS adopters, either as a result of a strategic decision or because it is almost unavoidable nowadays, given the fact that most commercial software also relies at some extent in OSS infrastructure. The way in which organizations adopt OSS affects and shapes their businesses. Therefore, knowing the impact of different OSS adoption strategies in the context of an organization may help improving the processes undertaken inside this organization and ultimately pave the road to strategic moves. In this paper, we propose to model OSS adoption strategies using a goal-oriented notation, in which different actors state their objectives and dependencies on each other. These models describe the consequences of adopting one such strategy or another: which are the strategic and operational goals that are supported, which are the resources that emerge, etc. The models rely on an OSS ontology, built upon a systematic literature review, which comprises the activities and resources that characterize these strategies. Different OSS adoption strategy models arrange these ontology elements in diverse ways. In order to assess which is the OSS adoption strategy that better fits the organization needs, the notion of model coverage is introduced, which allows to measure the degree of concordance among every strategy with the model of the organization by comparing the respective models. The approach is illustrated with an example of application in a big telecommunications company. (C) 2015 Elsevier B.V.

There is an ever-present need for readily available information and sophisticated means of communication. As a result, information and communication technologies are being deployed for application in various fields of endeavour some of which include virtual offices. A virtual office is essentially a simulated corporate environment that gives subscribers access to collaborative work related features, which act as a means of improving the way work is carried out in an organisation. Several organisations opt for the software services rendered by virtual offices because of their cost effectiveness and tendency to boost the collective productivity of these organisations. For reasons as such, the existence of virtual office software suites have become rampant, but the availability of its services are at a cost. This paper reports the design and implementation of an Educational Virtual Office using Free and Open-Source Software (FOSS) to relieve corporate organisations of the costly burdens of existing proprietary virtual office software. Tools used in achieving this feat are Drupal Web Content Management System (WCMS), readily available FOSS and a couple of other freeware, intelligently integrated to form a composite suite. The developed educational virtual office suite was deployed in the Department of Electrical and Information Engineering of Covenant University. A usability (user satisfaction) test was conducted. Analysis of the test results showed that questions related to user satisfaction scored more ``Strongly Agree{''} and ``Agree{''} points than ``Disagree{''} and ``Strongly Disagree{''}. This is a pointer to the fact that features such as the GUI of the web application and its navigation proved to have little or no challenges as at when the tests were carried out. Deployment of the developed educational virtual office suite has the significant advantage of low cost in comparison with proprietary virtual office suites with similar functionality. The fact that the suite was developed entirely using FOSS gives it all the attendant advantages that accrue from the employment of same from the system design bottom-Up. Such advantages as easy access to source code, which engenders easy upgrade of the component parts, come naturally.}, ISSN = {2340-1117}, ISBN = {978-84-617-0557-3}, ResearcherID-Numbers = {Atayero, Aderemi/O-1355-2013}, Unique-ID = {WOS:000366837205005}, } @inproceedings{ WOS:000281247700040, Author = {Dolores Gallego, M. and Bueno, Salvador}, Editor = {Sobh, T}, Title = {The role of user experience on FOSS acceptance}, Booktitle = {INNOVATIONS AND ADVANCES IN COMPUTER SCIENCES AND ENGINEERING}, Year = {2010}, Pages = {233-236}, Note = {International Joint Conference on Computer, Information, Systems Sciences and Engineering, Bridgeport, CT, DEC 05-13, 2008}, Abstract = {Free and open source software (FOSS) movement essentially arises like answer to the evolution occurred in the market from the software, characterized by the closing of the source code.

We validate our solution with a case study in which we update the control algorithm of a magnetic levitation device running at cycles of 1 kHz without dropping the ball.}, ISBN = {978-1-4799-4845-1}, Unique-ID = {WOS:000360999100026}, } @article{ WOS:000422543000004, Author = {McFerren, Graeme and van Zyl, Terence and Vahed, Anwar}, Title = {FOSS geospatial libraries in scientific workflow environments: experiences and directions}, Journal = {APPLIED GEOMATICS}, Year = {2012}, Volume = {4}, Number = {2, SI}, Pages = {85-93}, Month = {JUN}, Abstract = {In multiple research fields such as astronomy, bio-informatics, chem-informatics, geophysics and eco-informatics, scientists are increasingly turning to e-science and specifically scientific workflows as a way of improving, broadening, hastening and sharing their results. Enhanced collaboration, ad hoc access to tools, data and high-performance processing facilities are some of the gains to be made. Scientific workflows are concerned with, amongst others, supporting the repeatability and provenance of experiments. In context of three sets of research (wildfire research, flood modelling and the linking of disease outbreaks to multi-scale environmental conditions), we describe our efforts to provide geospatial capability for scientific workflow software environments to support researchers in exploring, integrating and visualising earth observation and geographic data in conjunction with other research data. We note that functionalities for data ingest (raster and vector), data transformation (reprojection and simplification), data export and spatial overlay operations commonly are required. We find a relative lack of support for geospatial data, services and these functions within several Free and Open Source Software (FOSS) scientific workflow packages. Furthermore, we highlight some software development and data encoding challenges faced when utilising various FOSS geospatial libraries within these scientific workflow environments. Finally, we offer suggestions for improving the integration of geospatial data as well as processing and analysis software tools into such environments.}, DOI = {10.1007/s12518-011-0062-0}, ISSN = {1866-9298}, EISSN = {1866-928X}, ResearcherID-Numbers = {van Zyl, Terence/B-9841-2008 }, ORCID-Numbers = {van Zyl, Terence/0000-0003-4281-630X}, Unique-ID = {WOS:000422543000004}, } @inproceedings{ WOS:000368495600008, Author = {Rajanen, Mikko and Iivari, Netta}, Editor = {Damiani, E and Frati, F and Riehle, D and Wasserman, AI}, Title = {Examining Usability Work and Culture in OSS}, Booktitle = {OPEN SOURCE SYSTEMS: ADOPTION AND IMPACT}, Series = {IFIP Advances in Information and Communication Technology}, Year = {2015}, Volume = {451}, Pages = {58-67}, Note = {11th IFIP WG 2.13 Annual International Conference on Open Source Systems (OSS), Florence, ITALY, MAY 16-17, 2015}, Organization = {IFIP WG 2 13; Google}, Abstract = {Organizational culture has been recognized as an influential factor affecting the successes and failures of usability work in organizations; however, there is a lack of research on organizational culture in open source software (OSS) development.

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others.

India is the largest consumer of water, with an estimated usage of around 300 cubic kilometers per year. Punjab, a north-western state of India, is an example of severe crises aquifer depletion due to unconstrained consumption of groundwater, leading to degradation of its quantity as well as quality. Thus it is of great importance to compile up-to-date information about the water requirement for its appropriate and sustainable use. Remote sensing and geographic information system (GIS) are the technologies that can provide efficient and effective information system to tackle the water quality \& water supply planning parameters. Thus, under the present study, a web-enabled water resource information system has been developed in the GIS environment for the SAS (Sahibzada Ajit Singh) Nagar and Patiala districts of Punjab by using the open source software MS4W and pmapper. This system provides digital information of natural, such as drainage, and man-made features like roads, canals, and tube wells with their location and so on, and also provide information related to water level, water quality of wells, and well depth for the study area. Such an information system can be very helpful for the administrators and can serve as a decision support system for planners and policy makers so that the areas where problems related to water quality can be identified and focused upon. The system can provide an effective and meaningful direction for the planning and development of both districts.}, DOI = {10.2166/wpt.2021.050}, EISSN = {1751-231X}, ResearcherID-Numbers = {Baweja, Samanpreet/AAD-1615-2021 DAS, SUSANTA/ABI-4091-2020 }, ORCID-Numbers = {Kaur, Samanpreet/0000-0003-3062-2428}, Unique-ID = {WOS:000675660100020}, } @article{ WOS:000347135300002, Author = {Knoerchen, Achim and Ketzler, Gunnar and Schneider, Christoph}, Title = {Implementation of a near-real time cross-border web-mapping platform on airborne particulate matter (PM) concentration with open-source software}, Journal = {COMPUTERS \& GEOSCIENCES}, Year = {2015}, Volume = {74}, Pages = {13-26}, Month = {JAN}, Abstract = {Although Europe has been growing together for the past decades, cross-border information platforms on environmental issues are still scarce.

It is generally seen that in a mixed meritocracy and autocracy governance model, the decision-making (DM) responsibility regarding what features are included in the OSS is shared among members from select roles; prominently the project leader. However, less examination has been made whether members from these roles are also prominent in DM discussions and how decisions are made, to show they play an integral role in the success of the project. We believe that to establish their influence, it is necessary to examine not only discussions of proposals in which the project leader makes the decisions, but also those where others make the decisions. Therefore, in this study, we examine the prominence of members performing different roles in: (i) making decisions, (ii) performing certain social roles in DM discussions (e.g., discussion starters), (iii) contributing to the OSS development social network through DM discussions, and (iv) how decisions are made under both scenarios.

Substantial technical expertise is required to conduct such rapid, reproducible, and adaptable analyses; however, such analyses can yield valuable insights for infection management and antimicrobial stewardship (AMS) teams. Objective: The aim of this study was to present the design, development, and testing of RadaR (Rapid analysis of diagnostic and antimicrobial patterns in R), a software app for infection management, and to ascertain whether RadaR can facilitate user-friendly, intuitive, and interactive analyses of large datasets in the absence of prior in-depth software or programming knowledge. Methods: RadaR was built in the open-source programming language R, using Shiny, an additional package to implement Web-app frameworks in R. It was developed in the context of a 1339-bed academic tertiary referral hospital to handle data of more than 180,000 admissions. Results: RadaR enabled visualization of analytical graphs and statistical summaries in a rapid and interactive manner. It allowed users to filter patient groups by 17 different criteria and investigate antimicrobial use, microbiological diagnostic use and results including antimicrobial resistance, and outcome in length of stay. Furthermore, with RadaR, results can be stratified and grouped to compare defined patient groups on the basis of individual patient features. Conclusions: AMS teams can use RadaR to identify areas within their institutions that might benefit from increased support and targeted interventions. It can be used for the assessment of diagnostic and therapeutic procedures and for visualizing and communicating analyses. RadaR demonstrated the feasibility of developing software tools for use in infection management and for AMS teams in an open-source approach, thus making it free to use and adaptable to different settings.}, DOI = {10.2196/12843}, Article-Number = {e12843}, ISSN = {1438-8871}, ResearcherID-Numbers = {Berends, Matthijs/AFJ-9786-2022 }, ORCID-Numbers = {Sinha, Bhanu/0000-0003-1634-0010 Luz, Christian/0000-0001-5809-5995 Berends, Matthijs/0000-0001-7620-1800 Glasner, Corinna/0000-0003-1241-1328 Lokate, Mariette/0000-0001-8664-3557}, Unique-ID = {WOS:000471614500001}, } @inproceedings{ WOS:000455226000029, Author = {Ferreira, Clarice and Souza, Cleice and Pinto, Gustavo and Steinmacher, Igor and Meirelles, Paulo}, Book-Group-Author = {Assoc Comp Machinery}, Title = {When Students Become Contributors: Leveraging OSS Contributions in Software Engineering Courses}, Booktitle = {SBES'18: PROCEEDINGS OF THE XXXII BRAZILIAN SYMPOSIUM ON SOFTWARE ENGINEERING}, Year = {2018}, Pages = {260-269}, Note = {32nd Brazilian Symposium on Software Engineering (SBES), Sao Carlos, BRAZIL, SEP 17-21, 2018}, Organization = {Faber Castell; B2W Digital; UOL; CeMEAI; Google; Univ Sao Paulo, Inst Ciencias Matematicas Computacao; Univ Fed Sao Carlos; Inst Fed Sao Paulo; IBM; Monitora}, Abstract = {Traditional Software Engineering courses commonly prioritize the teaching of methodologies and concepts in small and controlled environments.

Threedimensional models of the lesions were aligned and overlapped through the MeshLab software, which performed an automatic recording of the anatomical structures, based on the best fit. Qualitative and quantitative analyses of the changes in lesions size after treatment were performed with the 3DMeshMetric software. Results: The ITK-SNAP v. 3.0 showed the smaller value corresponding to the voxel count and the volume of the lesion segmented in yellow, indicating reduction in volume of the lesion after the treatment. A higher value of the mean intensity of the segmented image in yellow was also observed, which suggested new bone formation. Colour mapping and ``point value{''} tool allowed the visualization of the reduction of periapical lesions in several regions. Conclusions: Researchers and clinicians in the monitoring of endodontic periapical lesions have the opportunity to use open-source software.}, DOI = {10.1259/dmfr.20160293}, Article-Number = {20160293}, ISSN = {0250-832X}, EISSN = {1476-542X}, ResearcherID-Numbers = {Soares, Rodrigo/P-1199-2019 Sigurdsson, Asgeir/ABA-8829-2021 Souki, Bernardo/KYP-1977-2024 MARQUES, ALEXANDRE/IAM-1484-2023 Villoria, Eduardo/ABC-4932-2020 }, ORCID-Numbers = {Sigurdsson, Asgeir/0000-0002-6911-8248 Villamarim Soares, Rodrigo/0000-0001-7698-7532 Murad Villoria, Eduardo/0000-0002-4671-3650}, Unique-ID = {WOS:000395927500008}, } @article{ WOS:000600922900002, Author = {Dawood, Kareem A. and Sharif, Khaironi Y. and Ghani, Abdul A. and Zulzalil, H. and Zaidan, A.

However, these models lack consensus between scholars as well as standard bodies on a specific set of usability evaluation criteria. Retaining irrelevant criteria and omitting essential ones will mislead the direction of the usability evaluation. Objective: This study introduces a three-step method to develop a usability evaluation model in the context of OSS. Method: The fuzzy Delphi method has been employed to unify the usability evaluation criteria in the context of OSS. The first step in the method is the usability criteria analysis, which involves redefining and restructuring all collected usability criteria reported in the literature. The second step is fuzzy Delphi analysis, which includes the design and validates the fuzzy Delphi instrument and the utilisation of the fuzzy Delphi method to analyse the fuzziness consensus of experts' opinions on the usability evaluation criteria. The third step is the proposal of the OSS usability evaluation model. Results: A total of 124 usability criteria were identified, redefined, and restructured by creating groups of related meaning criteria. The result of the groupings generated 11 main criteria; the findings of the fuzzy Delphi narrowed down the criteria to only seven. The final set of criteria was sent back to the panellists for reconsideration of their responses. The panellists verified that these criteria are suitable in the evaluation of the usability of OSS. Discussion: The empirical analysis confirmed that the proposed evaluation model is acceptable in assessing the usability of OSS. Therefore, this model can be used as a reference metric for OSS usability evaluation which will have a practical benefit for the community in public and private organisations in helping the decision-maker to select the best OSS software package amongst the alternatives.}, DOI = {10.1016/j.infsof.2020.106453}, Article-Number = {106453}, ISSN = {0950-5849}, EISSN = {1873-6025}, ResearcherID-Numbers = {Dawood, Kareem/AAB-5709-2021 Zaidan, A./F-7289-2010 zaidan, bilal/AAJ-7841-2021 }, ORCID-Numbers = {zaidan, bilal/0000-0001-7412-8267 Dawood, Kareem Abbas/0000-0002-7024-0961}, Unique-ID = {WOS:000600922900002}, } @inproceedings{ WOS:000223038000002, Author = {Rönnlund, AR and Rosling, A}, Editor = {Kambayashi, Y and Tanaka, K and Rose, K}, Title = {Free software for a world in motion}, Booktitle = {SECOND INTERNATIONAL CONFERENCE ON CREATING, CONNECTING AND COLLABORATING THROUGH COMPUTING, PROCEEDINGS}, Year = {2004}, Pages = {14-19}, Note = {2nd International Conference on Creating, Connecting and Collaborating through Computing, Kyoto, JAPAN, JAN 29-30, 2004}, Organization = {Kyoto Univ, Dev Knowledge Soc Infrastruct, 21st Century Ctr Excellence Program; Res Promot Council, CRL Keihanna Open Lab; IPS; EIC; IEEE Kansai Sect}, Abstract = {This paper focus the need for new educational software environments for exploration of global statistics.

In this sense, refactoring edits aim at improving structural aspects of a code without changing its external behavior. However, studies show that developers tend to combine in a single commit refactorings and behavior-changing edits (extra edits) - floss-refactoring. Floss-refactorings can be error-prone and require careful handling. However, little has been done to understand how refactorings and extra edits relate in practice. In this work, we propose a strategy for extracting floss-refactoring data. Moreover, we mine code repositories of 16 open-source projects and analyse commits with floss refactoring related to Extract Method. Our results show that developers often combine Extract Method with inner method extra edits (e.g., statement insert), with an expected increase of 8-16\% of extra edits by each Extract Method. Moreover, some statements are more likely to be changed depending on the extra edit performed.}, DOI = {10.1145/3341105.3373893}, ISBN = {978-1-4503-6866-7}, ResearcherID-Numbers = {Andrade, Wilkerson/LGZ-5161-2024 }, ORCID-Numbers = {L.

For example, by highlighting project goals (e.g., a social good cause) to attract diverse contributors and mechanisms to acknowledge (e.g., a ``rising contributor{''} badge) existing contributors. Next, we conduct a project-specific evaluation with maintainers to better understand use cases in which this tool will be most helpful at supporting their plans for growth.

We consider: the variability of mathematical representation techniques on which the theoretical foundations of formal methods are based; formal methods multidisciplinarity; their capability to serve at a meta-level in providing the semantics of programming languages, specification and modelling languages as well as higher- level and domain-specific formal notations; and, finally, how some of these higher-level and domain-specific notations may be lifted at an interdisciplinary level. Within this historical review, we are inspired by Luis Barbosa's ``components as coalgebras{''} approach in seeing that the duality data-process is underlying all those aspects of formal methods. We also see that such a duality may not only be expressed in universal terms within category theory, but may also be characterised in practical terms and focused applications by two distinct logic paradigms, equational logic for the data and rewriting logic for the process, by two modelling directions, forward process definitions and backward data-driven process transformations, and by the distinction between syntax, defined by the data structures, and semantics, provided by rewrite rules. We use the Maude modelling language to illustrate the application of the data- process duality. In fact, Maude use equational logic to define data types and rewriting logic to express system evolution. Illustrative examples are from the areas of cognitive science and human- computer interaction (HCI). We then define a data-driven model transformation, which we call elaborative mining, , which adopts a backward perspective to recover a behaviour that was observed in real life but was not predicted forward by the original model. Finally, we see how the ``open source software bazaar{''}, which is a metaphor for the apparently chaotic open source development process, offers us a big data context to lift the driving process for model transformation from deterministic to statistical.}, DOI = {10.1016/j.jlamp.2024.101006}, EarlyAccessDate = {SEP 2024}, Article-Number = {101006}, ISSN = {2352-2208}, EISSN = {2352-2216}, Unique-ID = {WOS:001322403800001}, } @article{ WOS:001200861200010, Author = {Maina, Melisa and Basel, Valentin}, Title = {Reading Comprehension on Screen: A Free Software Educational Proposal}, Journal = {REICE-REVISTA IBEROAMERICANA SOBRE CALIDAD EFICACIA Y CAMBIO EN EDUCACION}, Year = {2024}, Volume = {22}, Number = {2}, Pages = {133-149}, Month = {APR}, Abstract = {The increasing digitalization of social life has substantially modified everyday practices, including teaching -learning processes.

Documenting and disseminating the public works heritage have now come of age, digitally speaking, with the adoption of new technologies both to further research on and heighten the esteem attributed to the public works heritage. Nonetheless, academic discourse rarely describes procedures for the 3D digitisation of heritage works comprehensible to non-expert readers with limited resources. Taking that premise as a starting point, with special attention to the determinants of the public works heritage, this article aims to define the general, open-source methodology covering 3D model data capture, information processing and optimisation. The article also discusses model dissemination strategies using free platforms and low-cost tools. The general discussion is illustrated with the case study of Ariza Bridge in Spain. This Renaissance-style structure dates from the second half of the sixteenth century. Despite its listing as a cultural heritage asset, the monument was flooded by the Giribaile reservoir waters in 1998 and is now only wholly visible during droughts. The application, developed with open-source software and implemented with free platforms and low-cost tools, features geo-referencing and is designed to be accessible to non-expert users.

Addressing a significant knowledge gap affecting this structural type, the study reveals how daily and seasonal fluctuations in environmental factors have a notable influence on its experimental modal parameters. A robust frequency-domain tracking algorithm is first developed to identify and follow the evolution of modal parameters over time, exploiting ambient vibration recordings acquired at sub-daily intervals on the structures. The procedure is systematically applied to the entire portfolio of case-study buildings and, in the first year of training, integrated with measurements of environmental parameters provided by nearby weather stations. The multivariate regression analysis indicates that temperature variation is the primary driver of the observed wandering of natural frequencies. The frequency-temperature relationship shows a positive correlation above zero degrees and, in several cases, a significant degree of nonlinearity already present in low-frequency global modes. Simple predictive models are proposed to address such nonlinear behavior, including freezing conditions and accounting for internal heating during winter. Leveraging these novel insights, the work develops strategies to improve the efficiency of data acquisition protocols and training periods, enabling the near-future extension of real-time condition assessment methodologies to the entire OSS network.}, DOI = {10.1007/s13349-024-00847-0}, EarlyAccessDate = {SEP 2024}, ISSN = {2190-5452}, EISSN = {2190-5479}, ResearcherID-Numbers = {Cattari, Serena/AAD-6007-2021 SIVORI, DANIELE/HKV-9314-2023 }, ORCID-Numbers = {SIVORI, DANIELE/0000-0002-6709-3710 Cattari, Serena/0000-0001-9459-5989}, Unique-ID = {WOS:001309243100001}, } @article{ WOS:001137942100001, Author = {Lin, Sen and Sun, Shiyong and Li, Zhengwei}, Title = {Clay-based 1D-2D halloysite\&g-C3N4 nanostructured meat floss for photocatalytic hydrogen evolution}, Journal = {HELIYON}, Year = {2023}, Volume = {9}, Number = {10}, Month = {OCT}, Abstract = {Graphitic carbon nitride (g-C3N4) has drawn extensive attention with some features including visible-light response as non-metallic semiconductor, low cost in raw material and green pollution-free for environment, but suffers from some issues such as fast charge carriers' recombination, easy aggregation, etc. In this work, the 1D-2D HNTs\&g-C3N4-X binary materials similar to meat floss pattern in a series of halloysite loading amounts are designed via a facile electrostatic self-assembly strategy with debris g-C3N4 after cell pulverizing treatment and HNTs that outwardly modified by cetyltrimethylammonium bromide (CTAB) as the building blocks.

First, this study is based on ethnographic research of free software projects and uses the resulting thick description to determine the meaning of sharing in this context. Second, the current literature on sharing usually takes user-generated content (UGC) platforms as its empirical reference, resulting in identifying a distinct meaning of sharing in this context. By combining the two sets of findings into a single narrative, this study makes three points: (1) the academic discourse on free software conceptualizing it as a form of gift-giving antithetical to the ways of capitalist production needs to be revised; (2) the use of sharing in the context of UGC platforms relies heavily on references to the culture of free software; (3) although representatives from both contexts claim to be taking part in the same sharing practices, there are substantial differences in the type of information being shared, the explicitness of the sharing mechanisms, and the organizational context of monetization of the shared objects.}, DOI = {10.1080/1369118X.2017.1418016}, ISSN = {1369-118X}, EISSN = {1468-4462}, ResearcherID-Numbers = {Karger, Tomas/S-6858-2019}, ORCID-Numbers = {Karger, Tomas/0000-0002-5624-8916}, Unique-ID = {WOS:000473830200008}, } @inproceedings{ WOS:000369183600019, Author = {Mendez Tapia, Lucia and Lopez, Lidia and Ayala, Claudia P. and Annosi, Maria Carmela}, Editor = {Ralyte, J and Espana, S and Pastor, O}, Title = {Towards an OSS Adoption Business Impact Assessment}, Booktitle = {PRACTICE OF ENTERPRISE MODELING, POEM 2015}, Series = {Lecture Notes in Business Information Processing}, Year = {2015}, Volume = {235}, Pages = {289-305}, Note = {8th IFIP WG 8.1 Working Conference on the Practice of Enterprise Modeling (PoEM), Univ Politecnica Valencia, Res Ctr Software Prod Methods, Valencia, SPAIN, NOV 10-12, 2015}, Organization = {IFIP WG 8 1}, Abstract = {Nowadays, the adoption of Open Source Software (OSS) by organizations is becoming a strategic need in a wide variety of application areas.

This model has 45 skills in the following 9 categories: technical skills, working styles, problem solving, contribution types, project-specific skills, interpersonal skills, external relations, management, and characteristics. Through a mix of qualitative and quantitative analyses, we find that OSS contributors are actively motivated to improve skills and perceive many benefits in sharing their skills with others.

In this position paper, we enrich the knowledge about the leaving stage by identifying sleeping and dead states, representing temporary and permanent brakes that developers take from contributing.

Researchers have extensively studied the human aspects of the OSS paradigm from the point of view of community formation to community evolution. A few studies relate community dynamics with OSS product attributes such as code quality. However, the impact of community dynamics on non-code contributions such as commits has not been explored. In this paper, the aim is to analyze the impact of community dynamics on syntactic quality of commit messages of an OSS project. We first propose and validate a commit message quality model, and then use that model to analyze the OSS projects. Empirical analysis of seven OSS projects available in the Git repository shows that a small group of contributors active at the same time in a project leads to high syntactic quality contributions.

The effect of this shift on project organization and developer collaboration is not well understood. In this paper, we use a theoretical argument to evaluate the appropriateness of using DVC in the context of two very common organization forms in OSS: a dictatorship and a peer group. We find that DVC facilitates large hierarchical communities as well as smaller groups of developers, while CVC allows for consensus-building by a peer group. We also find that the flexibility of DVC systems allows for diverse styles of developer collaboration. With CVC, changes flow up and down (and publicly) via a central repository. In contrast, DVC facilitates collaboration in which work output can flow sideways (and privately) between collaborators, with no repository being inherently more important or central. These sideways flows are a relatively new concept. Developers on the Linux project, who tend to be experienced DVC users, cluster around ``sandboxes:{''} repositories where developers can work together on a particular topic, isolating their changes from other developers. In this work, we focus on two large, mature OSS projects to illustrate these findings. However, we suggest that social media sites like GitHub may engender other original styles of collaboration that deserve further study.}, ISBN = {978-1-4673-6441-6}, ResearcherID-Numbers = {Barr, Earl T.

We begin by delineating the six critical events that constitute the Vulnerability-Patch lifecycle, leading to an in-depth exploration of the Vulnerability-Patch ecosystem. We then systematically review the databases commonly used in VD and SPD, and analyze their characteristics. Subsequently, we examine existing VD methods, focusing on traditional and deep learning based approaches.

For example, by highlighting project goals (e.g., a social good cause) to attract diverse contributors and mechanisms to acknowledge (e.g., a ``rising contributor{''} badge) existing contributors. Next, we conduct a project-specific evaluation with maintainers to better understand use cases in which this tool will be most helpful at supporting their plans for growth. From analyzing feedback, we find recommendations to be useful at signaling projects as welcoming and providing gentle nudges for maintainers to proactively recognize emerging contributors.

Understanding the use and characteristics of FLOSS deployed in the omics field is valuable for future innovation strategies, policy and funding priorities. We conducted a bibliometric, longitudinal study of the use of FLOSS in sepsis omics research from 2011 to 2015 in the United States, EU-28 and China. Because sepsis is an interdisciplinary field at the intersection of multiple omics technologies and medical specialties, it was chosen as a model innovation ecosystem for this empirical analysis, which used publicly available data. Despite development of and competition from proprietary commercial software, scholars in omics continue to employ FLOSS routinely, and independent of the type of omics technology they work with. The number of articles using FLOSS increased significantly over time in the EU-28, as opposed to the United States and China (R=0.96, p=0.004). Furthermore, in an era where sharing of knowledge is being strongly advocated and promoted by public agencies and social institutions, we discuss possible correlations between the use of FLOSS and various funding sources in omics research. These observations and analyses provide new insights into the use of FLOSS in sepsis omics research across three (supra)national regions. Further benchmarking studies are warranted for FLOSS trends in other omics fields and geographical settings.

In an earlier article, a proof-of-concept for a computer-aided visualization tool (also named STEVE, version 1.0) for stochastic theory education in water resources engineering was articulated {[}see, Schwenk et al. Comput. Appl. Eng. Educ., 2008, in press). Using lava Native Interfacing, it was shown that STEVE 1.0 could wrap a space time stochastic model written in any computer language and be independent of any specific language compiler during tool usage. This article describes the general philosophy, software design, and classroom usage for STEVE with significant improvements on visualization and user-friendliness (hence, rightfully called version 2.0). The software was created using the C++ programming language with the Microsoft Windows Applications Programming Interface (API). OpenGL was used for the visualization display, and the OpenGL Utility Toolkit (GLUT) was used to visualize text inside the OpenGL window. The instructor-specified simulation program on stochastic theory was written in Fortran 77. The application has user-friendly options for modifying input data and parameter specifications as desired by the instructor or the student user. STEVE 2.0 has been tested with the Windows XP and Windows Vista operating systems. For the benefit of interested users and software makers, we also provide the software application, a short tutorial and all pertinent source codes as freeware for download on our STEVE homepage at http://iweb.tntech.edu/saswe/steve.html.

The sensor, based on instantaneous measurements, functions as a position server for dual-axis solar trackers in photovoltaic plants. The proposed device has been developed with free software and hardware, which makes it a pioneering solution because it is open and accessible as well as capable of being improved by the scientific community, thereby contributing to the rapid advancement of technology. In addition, the device includes an algorithm developed ex professo that makes it possible to predetermine the regions of the celestial sphere for which, according to the geometric characteristics of the PV plant, there would be shading between the panels. In this way, solar trackers do not have to locate the Sun's position at all times according to astronomical models, while taking into account factors such as shadows or cloudiness that also affect levels of incident irradiance on solar collectors. Therefore, with this device, it is possible to provide photovoltaic plants with dual-axis solar tracking with a low-cost device that helps to optimise the trajectory of the trackers and, consequently, their radiative capture and energy production.}, DOI = {10.3390/s21030726}, Article-Number = {726}, EISSN = {1424-8220}, ResearcherID-Numbers = {Faz, José/AAB-1266-2021 Gomez Uceda, Francisco Javier/GQZ-2137-2022 Fernández-Ahumada, Luis M./GNW-2351-2022 VARO-MARTINEZ, Marta/F-9794-2016}, ORCID-Numbers = {Gomez Uceda, Francisco Javier/0000-0002-2350-0900 Ramirez Faz, Jose/0000-0002-6529-0649 Fernandez-Ahumada, Luis Manuel/0000-0002-2355-0190 VARO-MARTINEZ, Marta/0000-0003-4867-5528}, Unique-ID = {WOS:000615492600001}, } @article{ WOS:000252034300001, Author = {Jayashree, B. and Hanspal, Manindra S. and Srinivasan, Rajgopal and Vigneshwaran, R. and Varshney, Rajeev K. and Spurthi, N. and Eshwar, K. and Ramesh, N. and Chandra, S. and Hoisington, David A.}, Title = {An integrated pipeline of open source software adapted for multi-CPU architectures: Use in the large-scale identification of single nucleotide polymorphisms}, Journal = {COMPARATIVE AND FUNCTIONAL GENOMICS}, Year = {2007}, Pages = {1-7}, Abstract = {The large amounts of EST sequence data available from a single species of an organism as well as for several species within a genus provide an easy source of identification of intra-and interspecies single nucleotide polymorphisms (SNPs). In the case of model organisms, the data available are numerous, given the degree of redundancy in the deposited EST data. There are several available bioinformatics tools that can be used to mine this data; however, using them requires a certain level of expertise: the tools have to be used sequentially with accompanying format conversion and steps like clustering and assembly of sequences become time-intensive jobs even for moderately sized datasets. We report here a pipeline of open source software extended to run on multiple CPU architectures that can be used to mine large EST datasets for SNPs and identify restriction sites for assaying the SNPs so that cost-effective CAPS assays can be developed for SNP genotyping in genetics and breeding applications. At the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the pipeline has been implemented to run on a Paracel high-performance system consisting of four dual AMD Opteron processors running Linux with MPICH. The pipeline can be accessed through user-friendly web interfaces at http://hpc.icrisat.cgiar.org/PBSWeb and is available on request for academic use. We have validated the developed pipeline by mining chickpea ESTs for interspecies SNPs, development of CAPS assays for SNP genotyping, and confirmation of restriction digestion pattern at the sequence level.

Growing urbanization is one of the anthropic causes of UHI. The UHI phenomenon has a negative impact on the life quality of the local population (thermal discomfort, summer thermal shock, etc.), thus investigations and analyses on this topic are really useful and important for correct and sustainable urban planning; this study is included in this context. A multi-temporal analysis was performed in the municipality of Modena (Italy) to identify and estimate the Surface Urban Heat Island (SUHI, strictly correlated to the UHI phenomenon) from 2014 to 2017. For this purpose, Landsat-8 satellite images were processed with Quantum Geographic Information System (QGIS) to obtain the Land Surface Temperature (LST) and the Normalized Difference Vegetation Index (NDVI). For every pixel, LST and NDVI values of three regions of interest (ROI, i.e., Countryside, Suburbs, and City Center) were extracted and their correlations were investigated. A maximum variation of 6.4 degrees C in the LST values between City Center and Countryside was highlighted, confirming the presence of the SUHI phenomenon even in a medium-sized municipality like Modena. The implemented procedure demonstrates that satellite data are suitable for SUHI identification and estimation, therefore it could be a useful tool for public administration for urban planning policies.}, DOI = {10.3390/su10051678}, Article-Number = {1678}, EISSN = {2071-1050}, ResearcherID-Numbers = {Teggi, Sergio/K-2836-2015 }, ORCID-Numbers = {Teggi, Sergio/0000-0001-7375-0599 Despini, Francesca/0000-0002-6813-131X}, Unique-ID = {WOS:000435587100374}, } @article{ WOS:000714972700011, Author = {de Lima, Lucas T. and Fernandez-Fernandez, Sandra and Weiss, Carlos V.

The Bruun Rule for Google Earth Engine Model (BRGM) predicts the position of the shoreline with sea-level rise, using topographic and bathymetric data from Unmanned Aerial Vehicles and Coastal Modeling System, respectively. Based on the regional projections of the Special Report on Climate Change and Oceans and Cryosphere of the Intergovernmental Panel on Climate Change, the models were applied to a study case on the coast of Rio Grande do Sul-Brazil under different scenarios of sea-level rise expected by the end of this century. The results showed a maximum coastal retreat for the year 2100 of -502 m and -1727 m using EPR4Q and BRGM, respectively. The uBTM with Mapbiomas land use showed a maximum of 44.57 km(2) of urban area affected by sea-level flooding.

This research seeks to address the existing gap in accessible tools for high-throughput analysis of endothelial tube formation and cell invasion in vitro, facilitating the rapid assessment of drug sensitivity.MethodsOur approach involved annotating over 1000 2 mm Z-stacks of cancer and endothelial cell co-culture model and training machine learning models to automatically calculate cell coverage, cancer invasion depth, and microvessel dynamics. Specifically, cell coverage area was computed using focus stacking and Gaussian mixture models to generate thresholded Z-projections. Cancer invasion depth was determined using a ResNet-50 binary classification model, identifying which Z-planes contained invaded cells and measuring the total invasion depth. Lastly, microvessel dynamics were assessed through a U-Net Xception-style segmentation model for vessel prediction, the DisPerSE algorithm to extract an embedded graph, then graph analysis to quantify microvessel length and connectivity. To further validate our software, we reanalyzed an image set from a high-throughput drug screen involving a chemotherapy agent on a 3D cervical and endothelial co-culture model. Lastly, we applied this software to two naive image datasets from coculture lumen and microvascular fragment models.ResultsThe software accurately measured cell coverage, cancer invasion, and microvessel length, yielding drug sensitivity IC50 values with a 95\% confidence level compared to manual calculations. This approach significantly reduced the image processing time from weeks down to h. Furthermore, the software was able to calculate cell coverage, microvessel length, and invasion depth from two additional microphysiological models that were imaged with confocal microscopy, highlighting the versatility of the software.ConclusionsOur free and open source software offers an automated solution for quantifying 3D cell behavior in microphysiological models assessed using non-confocal microscopy, providing the broader Cellular and Molecular Bioengineering community with an alternative to standard confocal microscopy paired with proprietary software.This software can be found in our GitHub repository: https://github.com/fogg-lab/tissue-model-analysis-tools.}, DOI = {10.1007/s12195-024-00821-2}, EarlyAccessDate = {OCT 2024}, ISSN = {1865-5025}, EISSN = {1865-5033}, ResearcherID-Numbers = {Hettiaratchi, Marian/AAV-2446-2020 Hind, Laurel/JTD-2625-2023}, Unique-ID = {WOS:001329800800001}, } @article{ WOS:000405808200028, Author = {Rasool, Ghulam and Fazal, Nancy}, Title = {Evolution Prediction and Process Support of OSS Studies: A Systematic Mapping}, Journal = {ARABIAN JOURNAL FOR SCIENCE AND ENGINEERING}, Year = {2017}, Volume = {42}, Number = {8}, Pages = {3465-3502}, Month = {AUG}, Abstract = {Open source software (OSS) evolution is an important research domain, and it is continuously getting more and more attention of researchers.

During early succession colonization by mosses or plants significantly alters the pioneer microbial community composition through the photosynthetic carbon input. To provide further insights into this process, we investigated the three-year-old volcanic deposits of Mount Merapi, Indonesia. Samples were collected from unvegetated (BRD) and moss-covered (BRUD) sites. Forest site soil (FRS) near the volcanic deposit-covered area was also collected for reference. An analysis of BRD and BRUD revealed high culturable cell densities (1.7-8.5 x10(5)CFU g(-1)) despite their low total C (<0.01\%). FRS possessed high CFU (3 x10(6) g(-1)); however, its relative value per unit of total C (2.6\%) was lower than that of the deposit samples. Based on the tag pyrosequencing of 16S rRNA genes, the BRD bacterial community was characterized by a higher number of betaproteobacterial families (or genus), represented by chemolithotrophic Methylophilaceae, Leptothrix, and Sulfuricellaceae. In contrast, BRUD was predominated by different betaproteobacterial families, such as Oxalobacteraceae, Comamonadaceae, and Rhodocyclaceae. Some bacterial (Oxalobacteraceae) sequences were phylogenetically related to those of known moss-associated bacteria. Within the FRS community, Proteobacteria was the most abundant phylum, followed by Acidobacteria, whereas Burkholderiaceae was the most dominant bacterial family within FRS.

In order to detect types, and establish similarities, among Free/Libre/Open Source Software (FLOSS) systems, this paper considers three modular characteristics (functions, files and folders) and their evolution: how they are evolving with size, if they are constant across systems, and whether recurring evolutionary patterns are observed. Using these various-grained characteristics, a set of models for the evolution of modularization are extracted from evolving systems, and then used to extract similarities and types from a wide sample of FLOSS projects. This paper provides three contributions: first, it shows that several models are needed to encompass the variety of modularization patterns; second, it provides three types of models (uni-variate, bi-variate and tri-variate) for the evolution of modularization, with significant goodness-of-fit's.

In this work, we create a more comprehensive understanding of the hybrid OSS landscape by investigating what motivates companies to contribute and how they contribute to OSS. We conducted interviews with 20 participants who have different roles (e.g., CEO, OSPO Lead, Ecosystem Strategist) at 17 different companies of different sizes from large companies (e.g. Microsoft, RedHat, Google, Spotify) to startups. Data from semi-structured interviews reveal that company motivations can be categorized into four levels (Founders' Vision, Reputation, Business Advantage, and Reciprocity) and companies participate through different mechanisms (e.g., Developers' Time, Mentoring Time, Advocacy \& Promotion Time), each of which tie to the different types of motivations.

We foresee increasing costs for data collection and maintenance, leading to the risk of development budgets eaten up by commodity features, thus leaving little resources for differentiation and innovation. We therefore propose Open Collaborative Data (OCD) - a concept analogous to Open Source Software (OSS) as a means to share data. In contrast to Open Data (OD), which e.g., governmental agencies provide to catalyze innovation, OCD is shared in open collaboration between commercial organizations, similar to OSS. To achieve this, there is a need for technical infrastructure (e.g., tools for version and access control), licence models, and governance models, all of which have to be tailored for data. However, as data may be sensitive for privacy, anonymization and obfuscation of data is also a research challenge. In this paper, we define the concept of Open Collaborative Data, demonstrate it by map data and image recognition examples, and outline a research agenda for OCD in software engineering as a basis for more efficient evolution of software systems.}, DOI = {10.1109/ICSE-NIER.2019.00015}, ISBN = {978-1-7281-1758-4}, ResearcherID-Numbers = {Runeson, Per/H-5113-2019 }, ORCID-Numbers = {Runeson, Per/0000-0003-2795-4851}, Unique-ID = {WOS:000557879900007}, } @article{ WOS:000293182200006, Author = {Winter, Sidney G.}, Title = {Problems at the Foundation?

Among these principles, ``Brooks' Law{''} has been questioned in the Free Software context: large teams of developers, contrary to the law, will not need an increasingly growing number of communication channels. As advocates claim, this is due to the internal characteristics of the Free Software process: the high modularity of the code helps developers to work on comparted sections, without the need to coordinate with all other contriutors. This paper examines Brooks' Law in a Free Software context, and it studies the interaction of contributors to a large Free Software project, KDE. The network of interactions is analyzed and a summary term, the ``compaction{''}, is dynamically evaluated to test how the coordination mechanism evolves over time in the project. This paper argues that the claim of advocates holds true, but with limitations: in the KDE project, the few initial developers needed a significant amount of communication. The growth of KDE brought the need to break the number of overall communication channels to a significant extent. Finally, an established amount of 300 developers currently needs the same amount of communication as when the developers were only 10.

The modeling approach considers residual gravity field functionals generated by the well-known remove-compute-restore (RCR) technique where the long and short wavelength parts of the gravity signal are provided by a global geopotential model (GGM) and digital terrain model (DTM), respectively. A new data-adaptive network design methodology called k-SRBF is used to construct a network of SRBFs. The appropriate bandwidths (depths) are chosen using the generalized cross-validation (GCV) technique. The unknown SRBFs coefficients are estimated by applying the least-squares method where the extended Gauss Markov Model (GMM) with additional prior information is applied if the normal equation matrix is ill-conditioned. In such a case, the optimal regularization parameter is determined by variance component estimation (VCE). By utilizing parallel processing in every stage of the RCR technique, including creating the design matrix, the computational time is remarkably decreased relative to the number of processors used in the modeling. The performance of the software has been tested and validated in the Auvergne test area (France) on the basis of real terrestrial gravity data. The differences between estimated and observed height anomaly points (GNSS/leveling) amount to about 3 cm in terms of standard deviation (STD) for all kernels indicating that the SRBF\_Soft possesses the capability to be applied in regional gravity field modeling as an efficient and reliable software.}, DOI = {10.1007/s12145-022-00790-y}, EarlyAccessDate = {MAR 2022}, ISSN = {1865-0473}, EISSN = {1865-0481}, ResearcherID-Numbers = {ulug, Rasit/GQB-4462-2022 }, ORCID-Numbers = {Ulug, Rasit/0000-0002-2671-228X Karslioglu, Mahmut Onur/0000-0002-6124-9518}, Unique-ID = {WOS:000766042100001}, } @article{ WOS:000395117100005, Author = {Wang, Zhongjie and Perry, Dewayne E. and Xu, Xiaofei}, Title = {Characterizing Individualized Coding Contributions of OSS Developers from Topic Perspective}, Journal = {INTERNATIONAL JOURNAL OF SOFTWARE ENGINEERING AND KNOWLEDGE ENGINEERING}, Year = {2017}, Volume = {27}, Number = {1}, Pages = {91-124}, Month = {FEB}, Abstract = {Developers participating in an open source software (OSS) project make contributions to the project at different levels and aspects.

Dominant latent topics of each developer and the corresponding topic coverage degree are extracted from the source codes committed to the project repository, and such topic model is validated to be feasible for representing the individualized contribution features by statistics tests. Four types of topic evolution patterns are observed from the commit history of a developer. Temporal locality is partially exhibited in the topic evolution but there usually exhibit drastic changes between time-adjacent contributions of a developer. Respective proportions of the four evolution patterns and the degree of temporal locality in the topic evolution delineate a developer's individualized working habits in the time dimension.

Although previous work has examined the role of links in recommending high-priority tasks and reducing resource waste, the understanding of the actual usage of links in practice is still limited. To address the research gap, we conduct an empirical study based on the 5W1H model and data mining from five popular OSS projects on GitHub. We find that links originating from a PR are more common than the other three types of links, and links are more frequently created in Documentation. We also find that average duration between development units' create time in a link is half a year. We observed that link behaviors are very complex and the duration of link increases with the complexity of link structure.

Natural attenuation has as its basis the observation that ecosystem recovery appears to be largely a function of time. Sediment decomposition and the mixing of old sediments by bottom-dwelling organisms contribute to reduced contaminant concentrations. Knowledge of these processes is critical to the development of ecosystem recovery and waste management strategies. To evaluate the applicability of natural attenuation, information should be collected to determine whether surface sediment chemical concentrations will reach cleanup standards within a 10-year period through a combination of natural attenuation and adequate source control. The remedial design for the Thea Foss Waterway Superfund Site in Tacoma, Washington, employs the sequential risk mitigation approach. The EPA has selected a remedy involving natural attenuation (21 acres {[}8.4 hectares]), enhanced natural attenuation (4 acres {[}1.6 hectares]), dredging (650,000 cubic yards {[}494,000 cubic meters]), and capping (30 acres {[}12 hectares]) of this 8,000-foot (2,438-meter)-long waterway.

The spread of diseases like influenza depends on the mixing patterns within the population, and these mixing patterns depend in part on local factors including the spatial distribution and age structure of the population, the distribution of size and composition of households, employment status and commuting patterns of adults, and the size and age structure of schools. Finally, public health planners must take into account the health behavior patterns of the population, patterns that often vary according to socioeconomic factors such as race, household income, and education levels.

This version of FRED uses open-access census-based synthetic populations that capture the demographic and geographic heterogeneities of the population, including realistic household, school, and workplace social networks. FRED epidemic models are currently available for every state and county in the United States, and for selected international locations. Conclusions: State and county public health planners can use FRED to explore the effects of possible influenza epidemics in specific geographic regions of interest and to help evaluate the effect of interventions such as vaccination programs and school closure policies. FRED is available under a free open source license in order to contribute to the development of better modeling tools and to encourage open discussion of modeling tools being used to evaluate public health policies. We also welcome participation by other researchers in the further development of FRED.}, DOI = {10.1186/1471-2458-13-940}, Article-Number = {940}, EISSN = {1471-2458}, ResearcherID-Numbers = {Rosenfeld, Roni/HHN-8382-2022 Sriram, Anuroop/AAF-1926-2021 Guclu, Hasan/B-7080-2008 }, ORCID-Numbers = {Sriram, Anuroop/0000-0001-6295-7535 Fyshe, Alona/0000-0003-4367-0306 /0000-0002-5704-8094 Brown, Shawn/0000-0001-6980-8372 Rosenfeld, Ronald/0000-0002-3274-5862}, Unique-ID = {WOS:000329285300002}, } @article{ WOS:000864556500011, Author = {Yoon, Tae Jun and Maerzke, Katie A. and Currier, Robert P. and Findikoglu, Alp T.}, Title = {PyOECP: A flexible open-source software library for estimating and modeling the complex permittivity based on the open-ended coaxial probe (OECP) technique}, Journal = {COMPUTER PHYSICS COMMUNICATIONS}, Year = {2023}, Volume = {282}, Month = {JAN}, Abstract = {We present PyOECP, a Python-based flexible open-source software for estimating and modeling the complex permittivity obtained from the open-ended coaxial probe (OECP) technique. The transformation of the measured reflection coefficient to complex permittivity is performed based on three different methods. The software library contains the dielectric spectra of common reference liquids, which can be used to transform the reflection coefficient into the dielectric spectra. Several Python routines that are commonly employed (e.g., SciPy and NumPy) in the field of science and engineering are required only so that the users can alter the software structure depending on their needs. The modeling algorithm exploits the Markov Chain Monte Carlo method for the data regression. The discrete relaxation models can be built by a proper combination of well-known relaxation models. In addition to these models, electrode polarization, a typical measurement artifact for interpreting dielectric spectra, can be incorporated into the modeling algorithm. A continuous relaxation model, which solves the Fredholm integral equation of the first kind (a mathematically ill-posed problem), is also included. This open-source software enables users to freely adjust the physical parameters to obtain physical insight into their materials under test and will be consistently updated for more accurate measurement and interpretation of dielectric spectra in an automated manner. This work describes the theoretical and mathematical background of the software, lays out the workflow, and validates the software functionality based on both synthetic and empirical data included in the software.

The obtained dielectric spectra can be useful for understanding the relaxation processes in an arbitrary fluid. Solution method: The reflection coefficient data is obtained as a text format from a Vector Network Analyzer (VNA). This text data is parsed into a Numpy array. Three different modules (Stuchly, Marsland, and Komarov) can be used to transform the parsed reflection coefficient data into complex permittivity as a function of the measurement frequency. The resultant dielectric spectra can be dissected and interpreted by fitting either discrete relaxation model(s) based on the Markov Chain Monte Carlo algorithm or a continuous relaxation model by applying the Zasetsky-Buchner method.

The research highlights the highly transient behavior of fast flood flows, particularly when carrying debris, and their effect on bridge superstructures. Utilizing a Digital Elevation Model to extract cross-sectional and elevation data, the research examined 23 profiles over 800 m of the river. The results indicate that the maximum allowable water depth in front of the bridge is 4.73 m, with a Manning's coefficient of 0.03 and a longitudinal slope of 9 m per kilometer. Therefore, a novel method to identify the risks through HEC-RAS modeling significantly improves the conservation of masonry bridges by providing precise topographical and hydrological data for accurate simulations. Moreover, the detailed information obtained from LIDAR and UAV photogrammetry about the bridge's materials and structures can be incorporated into the conservation models. This comprehensive approach ensures that preservation efforts are not only addressing the immediate hydrodynamic threats but are also informed by a thorough understanding of the bridge's structural and material conditions. Understanding rating curves is essential for water management and flood forecasting, with the study confirming a Manning roughness coefficient of 0.03 as suitable for smooth open-channel flows and emphasizing the importance of geomorphological conditions in hydraulic simulation.}, DOI = {10.3390/rs16162994}, Article-Number = {2994}, EISSN = {2072-4292}, ORCID-Numbers = {PEPE, MASSIMILIANO/0000-0003-2508-5066}, Unique-ID = {WOS:001306003600001}, } @article{ WOS:000857679200001, Author = {Cutugno, Matteo and Robustelli, Umberto and Pugliano, Giovanni}, Title = {Structure-from-Motion 3D Reconstruction of the Historical Overpass Ponte della Cerra: A Comparison between MicMac® Open Source Software and Metashape®}, Journal = {DRONES}, Year = {2022}, Volume = {6}, Number = {9}, Month = {SEP}, Abstract = {In recent years, the performance of free-and-open-source software (FOSS) for image processing has significantly increased. This trend, as well as technological advancements in the unmanned aerial vehicle (UAV) industry, have opened blue skies for both researchers and surveyors. In this study, we aimed to assess the quality of the sparse point cloud obtained with a consumer UAV and a FOSS. To achieve this goal, we also process the same image dataset with a commercial software package using its results as a term of comparison. Various analyses were conducted, such as the image residuals analysis, the statistical analysis of GCPs and CPs errors, the relative accuracy assessment, and the Cloud-to-Cloud distance comparison. A support survey was conducted to measure 16 markers identified on the object. In particular, 12 of these were used as ground control points to scale the 3D model, while the remaining 4 were used as check points to assess the quality of the scaling procedure by examining the residuals. Results indicate that the sparse clouds obtained are comparable. MicMac (R) has mean image residuals equal to 0.770 pixels while for Metashape (R) is 0.735 pixels. In addition, the 3D errors on control points are similar: the mean 3D error for MicMac (R) is equal to 0.037 m with a standard deviation of 0.017 m, whereas for Metashape (R), it is 0.031 m with a standard deviation equal to 0.015 m.

In this contribution, the authors acquire images using a prototype drone with a low-cost camera mounted upward over the body of the drone. The proposed solution was tested on a bridge in the city of Turin (Italy). The captured data was processed via photogrammetric process using the opensource Micmac solution.

It is known that for the unidirectional composites the most significant distortion of the structure of the host material takes place when the optical fiber is embedded perpendicular to the direction of the reinforcement of the composite material layers. However, the internal structure of the composites with woven layer reinforcement scheme is significantly different. And the embedding of such a foreign object as an optical fiber can cause a basically other, as compared to unidirectional composites, change in the internal structure. Cross-sectional studies were performed using an optical microscope. The analysis of cross-sections of PCM samples was carried out with the aim of studying the changes in the structure of the layered composite with woven fabric reinforcement due to the embedding of the fiber-optic sensors. A comparison of the obtained images showed that the microstructure of the studied samples is better seen on polished surfaces. In the absence of polishing on a number of samples, the optical fiber is not visually noticeable or poorly distinguishable. Analysis of the obtained images showed that there is an insignificant distortion of the internal structure of the material in the area with embedded optical fiber without the formation of a resin pocket for all studied GFRP samples. At the same time, when analyzing CFRP samples, the effect of embedding of the optical fiber on the microstructure of the composite was not observed. 2019 The Authors.

The focus of the paper lies in a proof-of-concept for a novel means to develop and execute pervasive services, with simplicity and maintainability as prime drivers. The essence of this approach is the novel integration of the policy-based management (PBM) techniques and the model-driven architecture (MDA) techniques for specifying pervasive services and their behaviour, together with auto-generation of middleware implementation and policy enablement. The presence of policies provides pervasive services with the high flexibility and adaptability needed for dealing with changing environments and resource availabilities, while the introduction of MDA for defining pervasive service information models fundamentally solves the information modelling puzzle of current policy-based approaches. Additionally, MDA's middleware-neutral feature benefits the smooth evolution of pervasive services as a piece of software artefact in the face of heterogeneous devices and platforms. A preliminary case study has demonstrated the practical feasibility and benefits of this approach. The case study revolves around an ICT service called TEANU - transparent enterprise access for nomadic user.

In this context, the Self-Determination Theory (SDT) was the theoretical approach through which we identified the motivational factors. Specifically, three SDT motivations were added: (1) autonomy, (2) competence and (3) relatedness. The 104 selected experts were managers from companies with employees who have studied in educational centers where OSS usage is mandatory. The results show that managers perceive that OSS training incentivizes OSS implementations in companies.

These cylinders offer light weight, corrosion resistance, dimensional stability, and the ability to store more air than equivalent metal tanks. The design methodology currently used for composite tanks, however, cannot yet guarantee their safe operation. Accordingly, the U.S. Department of Transportation (DOT) is unable to issue full certification of filament-wound tanks. Rather, some types of composite pressure tanks currently are manufactured under DOT Exemption, TC Regulation 3FCM. The composite tank industry would benefit by improving the safety of operating these tanks. The interest in developing composite pressure tanks is here and the manufacturing technology is mature. What is needed, however, is a means of insuring that composite tanks are as safe to operate as metal tanks. This will facilitate DOT certification and appeal to consumers. This paper discusses a fiber optic sensor system embedded into the composite shell wall as a structural health monitor. Using a simple, low-cost optical fiber sensor and a modified commercial connector, ``smart{''} tanks can be monitored continuously for structural integrity. The opportunity to provide such continuity in structural health monitoring should have a significant positive impact on obtaining DOT certifications and extending product useful life. This paper presents the results of a design program to develop a new filament-wound composite cylinder containing a fiber-optic sensor system (FOSS). The purpose of FOSS is to monitor the structural integrity of the composite material each time the tank is refilled with pressurized gas. Continuous monitoring for material degradation will be an important factor that determines tank recertification intervals and useful tank life. One of the greatest challenges of this design program has been to develop an optical connector that allows external instrumentation to be ``plugged into{''} the composite wall to read optical signals that correlate with structural health. ``While embedding fiber sensors has become routine, ingress to and egress from the embedded units remain a major stumbling block{''} (Spillman, 1995). A simple modification to a commercial connector is proposed for this application. The design and manufacture of the prototype FOSS cylinder shown in Figure 1 are described in this paper. Connector performance and the overall performance of a prototype Type III tank consisting of an aluminum liner, an E-glass/epoxy filament-wound overwrap, and an embedded FOSS are discussed. Results of a pressure test to assess FOSS performance are presented.}, ISSN = {1098-6189}, ISBN = {1-880653-55-9}, Unique-ID = {WOS:000171430500029}, } @inproceedings{ WOS:000613139300029, Author = {Anderson, John and Steinmacher, Igor and Rodeghero, Paige}, Book-Group-Author = {IEEE}, Title = {Assessing the Characteristics of FOSS Contributions in Network Automation Projects}, Booktitle = {2020 IEEE INTERNATIONAL CONFERENCE ON SOFTWARE MAINTENANCE AND EVOLUTION (ICSME 2020)}, Series = {Proceedings-IEEE International Conference on Software Maintenance}, Year = {2020}, Pages = {324-335}, Note = {36th IEEE International Conference on Software Maintenance and Evolution (ICSME), ELECTR NETWORK, SEP 27-OCT 03, 2020}, Organization = {IEEE; IEEE Comp Soc}, Abstract = {Network Automation seeks to integrate software solutions that aid in the management and maintenance of modern networks. In industry, large organizations see dedicated software engineering resources within a networking team. However, in the broader industry, it is more common to see traditional network engineers working on network automation. With the growth of Free and Open Source Software (FOSS), network automation software solutions also started to adhere to this development model. However, as it is known from the literature, onboarding to FOSS projects is not a trivial task and may be more challenging for people without a software development background. In this paper, we study network automation FOSS projects, which are seeing a large number of new contributors who do not have traditional software engineering skills. We analyze a set of data collected from pull requests and issues collected from 81 GitHub projects (71 network automation projects, and 10 top-projects from other domains), to identify the characteristics that are specific to first-time project contributors in the network automation domain. Our results show that pull requests in the Network Automation domain differ from those in the Top-10 set and the existing literature. At the same time that Network Automation projects are more inclusive (rejection rate: 12\% vs. 28\% on Top-10), the pull request latency is longer in this specific domain, especially for first-timers.}, DOI = {10.1109/ICSME46990.2020.00039}, ISSN = {1063-6773}, ISBN = {978-1-7281-5619-4}, ResearcherID-Numbers = {Igor, Steinmacher/B-6414-2012}, Unique-ID = {WOS:000613139300029}, } @article{ WOS:000439985100002, Author = {Braught, Grant and Maccormick, John and Bowring, James and Burke, Quinn and Cutler, Barbara and Goldschmidt, David and Krishnamoorthy, Mukkai and Turner, Wesley and Huss-Lederman, Steven and Mackellar, Bonnie and Tucker, Allen}, Title = {A Multi-Institutional Perspective on H/FOSS Projects in the Computing Curriculum}, Journal = {ACM TRANSACTIONS ON COMPUTING EDUCATION}, Year = {2018}, Volume = {18}, Number = {2, SI}, Month = {JUL}, Abstract = {Many computer science programs have capstone experiences or project courses that allow students to integrate knowledge from the full breadth of their major.

We then discuss the themes that are common across the models, such as project selection, team formation, mentoring, and student assessment.

This analytic distinction presents some limitations in explaining how coordination is reached in organizations characterized by distributed teams, scarce face to face meetings and fuzzy and changing lines of authority, as in free/libre open source software (FLOSS) development. Analyzing empirical illustrations from two FLOSS projects, we highlight the existence of a peculiar model, stigmergic coordination, which includes aspects of both implicit and explicit mechanisms. The work product itself (implicit) and the characteristics under which it is shared (explicit) play an under-appreciated role in helping software developers manage dependencies as they arise. We develop this argument beyond the existing literature by working with an existing coordination framework, considering the role that the codebase itself might play at each step. We also discuss the features and the practices to support stigmergic coordination in distributed teams, as well as recommendations for future research. (C) 2016 The Authors.

The use of Free and Open Source Software (FOSS) projects is one attractive approach for providing students with easy access to a complex, ongoing project of size that is supported by a professional community. Humanitarian FOSS (HFOSS) projects hold the additional appeal to students of developing software that will benefit the human condition. However, student involvement in HFOSS projects can be somewhat unpredictable and less controllable than the development of home-grown projects or projects with an industry partner. Student participation in an HFOSS project means that students are dependent, at least somewhat, on the goals, schedule, and constraints of the HFOSS project itself. Therefore, learning is somewhat reliant on the progress of the HFOSS project. This paper presents results of a multi-year study of student perceptions of learning related to software engineering knowledge and skills while involved in an HFOSS project.

It is without doubt that an increasing number of software and hardware vendors are investing significant amounts in open Source software in a number of ways.

This chapter attempts a holistic approach on the analysis of the OSS phenomenon and its impact on welfare. The main entities of the OSS ecosystem are identified and analysed under the scope of the main factors affecting welfare: innovation, competition and productivity. For that purpose an all encompassing model of the OSS ecosystem is created to reflect the interactions among its entities as well as the direct and indirect effects on welfare factors. Innovation and productivity are promoted by the accumulation of knowledge and human capital input by individuals as well as by enterprises. OSS as an innovative mode of production has created market opportunities and new sustainable business models, creating the appropriate conditions for new entrances and a raise in competition in the software market. To support this, a market concentration index, the HHI index, is tested over the case of web servers.

Open source software solutions offer great opportunities for cost reduction and quality improvement, especially for small and medium enterprises that typically have to address major difficulties due to the limited resources available for selecting and adopting a new software system. Objective: This paper aims to provide support for selecting the open source software that is most suitable to the specific needs of an enterprise from among the options offering equivalent or overlapping functionality. Method: This paper proposes a framework for evaluating the quality and functionality of open source software systems. The name of the framework is EFFORT (Evaluation Framework for Free/Open souRce projecTs). It supports the evaluation of product quality, community trustworthiness and product attractiveness. The framework needs to be customised to the analysis of software systems for a specific context. Results: The paper presents the customisation of EFFORT for evaluating Enterprise Resource Planning (ERP) open source software systems. The customised framework was applied to the evaluation and comparison of five ERP open source software systems. The results obtained permitted both the refinement of the measurement framework and the identification of the ERP open source software system that achieved the highest score for each chosen characteristic. Conclusion: EFFORT is a useful tool for evaluating and selecting an open source software system. It may significantly reduce the amount of negotiation conducted among an enterprise's members and reduce the time and cost required for gathering and interpreting data. The EFFORT framework also considers the users' opinions by introducing relevance markers associated with the metrics and questions in the data aggregation process. (C) 2013 Elsevier B.V.

The initial level allows independent assemble the simulator from publicly available elements (laptop, webcam, weapon layouts, IR LEDs), which can contribute to widespread use both in schools and at home, but is low in accuracy and manufacturabili (requires daily calibration). The basic level also allows independent assemble the simulator, and less publicly available elements (laptop, projector, mockup weapons, laser emitters, FHD camera), which allows to be used both in schools and in DOSAAF structures, and has acceptable accuracy and manufacturability (a weekly calibration is enough, but assembling a mock-up weapon with laser emitters requires adjustments).

The South Australian Government is committed to establishing a comprehensive, adequate and representative system of 19 marine protected areas (MPAs) by 2010. Each MPA will be the target for detailed investigations into its biophysical, ecological, social, economic and cultural assets. The aim is to use this information to delineate each MPA into a series of zones that offer various levels of protection and use. At the highest level all marine use and extraction activities will be excluded to allow maximum protection of species diversity and habitat. Community consultation and collaboration is therefore critical for successful MPA establishment. A demand exists for the development of a process that allows public participation within a conservation planning environment. The concept of excluding certain activities, including recreational fishing, has generated much interest in the local media. Recent headlines such as `Calls to Shelve Marine Parks', `Anglers Fight For Future of Jetty Fishing' and `330+ Submissions on MPA Proposal' demonstrate the importance of open consultation and the need to provide an inclusive and transparent decision-making process for the design of MPAs. A decision support tool can facilitate decision-making within a negotiating and conflict resolution environment. We have collated and processed a large database of spatial layers describing the biophysical and human-use features of the marine environment. The biophysical data was then used to identify surrogate ecological regions within the Encounter Pilot MPA. The datasets were categorised into classes describing bathymetry, sea surface temperature, chlorophyll `a' concentration levels, benthic and coastal habitat types, and shoreline exposure and type. Locations that most efficiently represent these surrogates of biodiversity were selected using a common mathematical integer programming optimisation algorithm. Established conservation planning principles underpin this research. Inputs into OSS are a suite of environmental, social, cultural and economic datasets. Optimal solutions are found using integer programming algorithms. Implementation is within a Geographic Information System environment (ESRI's ArcGIS) and third-party commercial software (ILOG's CPLEX) provides the optimisation engine. The user interface of OSS can be accessed through a toolbar button and comprises a series of input modules. Fields are quick and easy to populate and in many cases are read directly from an ArcGIS map document Table of Contents. Solutions are found in less than 1 minute when using datasets described in this paper OSSThis paper briefly demonstrates the application of systematic conservation planning to optimal MPA design and the development of OSS, and explores options for public participation. We demonstrate how OSS and systematic conservation planning can be taken to the wider community to produce on-the-fly outputs. Our novel approach has the potential to build partnerships with community groups and give the community a sense of ownership in the decision-making process.

Our conjecture is that an inheritance hierarchy will tend to grow `breadth-wise' rather than `depth-wise'. This claim is made on the basis that developers will avoid extending depth in favour of breadth because of the inherent complexity of having to understand the functionality of superclasses. Thus the goal of our study is to investigate this empirically. We conduct an empirical study of seven Java Open-Source Systems (OSSs) over a series of releases to observe the nature and location of changes within the inheritance hierarchies. Results showed a strong tendency for classes to be added at levels one and two of the hierarchy (rather than anywhere else). Over 96\% of classes added over the course of the versions of all systems were at level I or level 2. The results suggest that changes cluster in the shallow levels of a hierarchy; this is relevant for developers since it indicates where remedial activities such as refactoring should be focused.}, DOI = {10.1109/ASWEC.2008.78}, ISBN = {978-0-7695-3100-7}, ResearcherID-Numbers = {Shepperd, Martin/F-9683-2013}, ORCID-Numbers = {Shepperd, Martin/0000-0003-1874-6145}, Unique-ID = {WOS:000255154800028}, } @inproceedings{ WOS:000281247700010, Author = {Bueno, Salvador and Dolores Gallego, M.}, Editor = {Sobh, T}, Title = {Evaluating acceptance of OSS-ERP based on user perceptions}, Booktitle = {INNOVATIONS AND ADVANCES IN COMPUTER SCIENCES AND ENGINEERING}, Year = {2010}, Pages = {55-60}, Note = {International Joint Conference on Computer, Information, Systems Sciences and Engineering, Bridgeport, CT, DEC 05-13, 2008}, Abstract = {Organizations implement Enterprise Resource Planning (ERP) systems with the objective of reaching operational efficiency and the incorporation to new markets through the information flow control on time of the entire organization.

Method: We surveyed participants from 15 FLOSS projects, asking a series of open-ended, closed-ended, and behavioral scale questions to gather information about the issue of gender in FLOSS projects. Results: Though many of those we surveyed expressed a positive sentiment towards females who participate in FLOSS projects, some were still strongly against their inclusion. Often, the respondents who were against inclusiveness also believed their own sentiments were the prevailing belief in the community, contrary to our findings. Others did not see the purpose of attempting to be inclusive, expressing the sentiment that a discussion of gender has no place in FLOSS.

To understand how developers identify these projects, their motivations for contributing, and challenges they face, we conducted 21 semi-structured interviews with OSS for Social Good (OSS4SG) contributors. From our interview analysis, we identified themes of contribution styles that we wanted to understand at scale by deploying a survey to over 5765 OSS and Open Source Software for Social Good contributors. From our quantitative analysis of 517 responses, we find that the majority of contributors demonstrate a distinction between OSS4SG and OSS. Likewise, contributors described definitions based on what societal issue the project was to mitigate and who the outcomes of the project were going to benefit. In addition, we find that OSS4SG contributors focus less on benefiting themselves by padding their resume with new technology skills and are more interested in leaving their mark on society at statistically significant levels. We also find that OSS4SG contributors evaluate the owners of the project significantly more than OSS contributors. These findings inform implications to help contributors identify high societal impact projects, help project maintainers reduce barriers to entry, and help organizations understand why contributors are drawn to these projects to sustain active participation.}, DOI = {10.1109/ICSE43902.2021.00096}, ISSN = {0270-5257}, ISBN = {978-0-7381-1319-7}, ORCID-Numbers = {Huang, Yu/0000-0003-2730-5077}, Unique-ID = {WOS:000684601800083}, } @inproceedings{ WOS:000424861900086, Author = {Fukuyori, Masahiro and Umekawa, Ryuichi and Fujino, Hiroshi and Yamaguchi, Junya and Ariyama, Kota}, Editor = {Reisman, S and Ahamed, SI and Demartini, C and Conte, T and Liu, L and Claycomb, W and Nakamura, M and Tovar, E and Cimato, S and Lung, CH and Takakura, H and Yang, JJ and Akiyama, T and Zhang, Z and Hasan, K}, Title = {An Approach Based on Structural Differences to Expedite Applying OSS updates to Products}, Booktitle = {2017 IEEE 41ST ANNUAL COMPUTER SOFTWARE AND APPLICATIONS CONFERENCE (COMPSAC), VOL 2}, Series = {Proceedings International Computer Software and Applications Conference}, Year = {2017}, Pages = {445-450}, Note = {41st IEEE Annual Computer Software and Applications Conference (COMPSAC), Torino, ITALY, JUL 04-08, 2017}, Organization = {IEEE; IEEE Comp Soc}, Abstract = {Open source software (OSS)-based product development takes advantage of feature updates and bug fixes from OSS communities.

Therefore, the aim of this study was to develop a widely-usable data-collection and data-analysis workflow that could be applied in medical departments to perform high-volume relational data analysis on real-time data. Methods: A sample project, based on a research database on prostate-specific-membrane-antigen/positron-emission-tomography scans performed in prostate cancer patients at our department, was used to develop a new workflow for data-collection and data-analysis. A checklist of requirements for a successful data-collection/analysis strategy, based on shared clinical research experience, was used as reference standard. Software libraries were selected based on widespread availability, reliability, cost, and technical expertise of the research team (REDCap-v11.0.0 for collaborative data-collection, Python-v3.8.5 for data retrieval and SQLite-v3.31.1 for data storage). The primary objective of this study was to develop and implement a workflow to: a) easily store large volumes of structured data into a relational database, b) perform scripted analyses on relational data retrieved in real-time from the database. The secondary objective was to enhance the strategy cost-effectiveness by using open-source/cost-free software libraries. Results: A fully working data strategy was developed and successfully applied to a sample research project. The REDCap platform provided a remote and secure method to collaboratively collect large volumes of standardized relational data, with low technical difficulty and role-based access-control. A Python software was coded to retrieve live data through the REDCap-API and persist them to an SQLite database, preserving data-relationships. The SQL-language enabled complex datasets retrieval, while Python allowed for scripted data computation and analysis. Only cost-free software libraries were used and the sample code was made available through a GitHub repository. Conclusions: A REDCap-based data-collection and data-analysis workflow, suitable for high-volume relational data-analysis on live data, was developed and successfully implemented using open-source software.

Individual object motions typically display a level of dynamic regularity reflecting the existence of an underlying physics or biology. Best results are obtained when this local information is exploited. Additionally, if the particle number is known to be approximately constant, a large number of tracking scenarios may be rejected on the basis that they are not compatible with a known maximum particle velocity. This represents information of a global nature, which should ideally be exploited too. Some time ago, we devised an efficient algorithm that exploited both types of information. The tracking task was reduced to a max-flow min-cost problem instance through a novel graph structure that comprised vertices representing objects from three consecutive image frames. The algorithm is explained here for the first time. A user-friendly implementation is provided, and the specific relaxation mechanism responsible for the method's effectiveness is uncovered. The software is particularly competitive for complex dynamics such as dense antiparallel flows, or in situations where object displacements are considerable.

This approach re-scales Marchs (1991) framework and applies it to characterize the innovation system of a distributed organization of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two coupled processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from lurking (not contributing or contributing to projects without becoming a member) to laboring (joining one or more projects as members), and to launching (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered developers fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platforms global dynamics.}, DOI = {10.1093/icc/dtn026}, ISSN = {0960-6491}, EISSN = {1464-3650}, ORCID-Numbers = {RULLANI, FRANCESCO/0000-0001-6142-856X}, Unique-ID = {WOS:000258138700003}, } @inproceedings{ WOS:000426896900258, Author = {de Oliveira, Francisco Kelsen and de Oliveira, Max Brandao and Gomes, Alex Sandro and Queiros, Leandro Marques}, Book-Group-Author = {IEEE}, Title = {RECREIO: Floss as SAAS for Sharing of Educational Resources}, Booktitle = {2017 12TH IBERIAN CONFERENCE ON INFORMATION SYSTEMS AND TECHNOLOGIES (CISTI)}, Series = {Iberian Conference on Information Systems and Technologies}, Year = {2017}, Note = {12th Iberian Conference on Information Systems and Technologies (CISTI), Lisbon, PORTUGAL, JUN 21-24, 2017}, Organization = {Assoc Iberica Sistemas Tecnologias Informaco; Inst Univ Lisboa; Asoc Tecnicos Informatica; Assoc Portuguesa Empreendedorismo; IEEE SMC; IEEE Portugal Sect; FCA; Lidel; SAS; Silabo; TAP}, Abstract = {The objective of this study was to verify if a development model of Units of Learning (UoLs), supported by UoLs authoring tools, that meet the usability criteria and abstract advanced knowledge in programming language by the developers, effectively provides the use and implementation of such resources by teachers in all areas of high school (in this first phase of the research) with few skills with technology.

This is multi-platform software developed in the Java programming language, designed with a remarkably user-friendly graphical interface for the computation of a collection of information-theoretic functions adapted for rank-based unsupervised and supervised feature selection tasks. A total of 20 feature selection parameters are presented, with the unsupervised and supervised frameworks represented by 10 approaches in each case. Several information-theoretic parameters traditionally used as molecular descriptors (MDs) are adapted for use as unsupervised rank-based feature selection methods. On the other hand, a generalization scheme for the previously defined differential Shannon's entropy is discussed, as well as the introduction of Jeffreys information measure for supervised feature selection. Moreover, well-known information-theoretic feature selection parameters, such as information gain, gain ratio, and symmetrical uncertainty are incorporated to the IMMAN software (http://mobiosd-hub.com/imman-soft/), following an equal-interval discretization approach. IMMAN offers data pre-processing functionalities, such as missing values processing, dataset partitioning, and browsing. Moreover, single parameter or ensemble (multi-criteria) ranking options are provided. Consequently, this software is suitable for tasks like dimensionality reduction, feature ranking, as well as comparative diversity analysis of data matrices. Simple examples of applications performed with this program are presented. A comparative study between IMMAN and WEKA feature selection tools using the Arcene dataset was performed, demonstrating similar behavior. In addition, it is revealed that the use of IMMAN unsupervised feature selection methods improves the performance of both IMMAN and WEKA supervised algorithms.

The Mill on the Floss is thus a novel whose structure is wholly based on the blending of several types and subgenres.

Their low budget characteristics make the vertical applications these users need natural targets for free/open source software (F/OSS) development efforts. The lack of technological challenges however, does not motivate experienced programmers to specify, code and test verticals. We are thus left with a problem of developing verticals which do not attract ROSS volunteers and whose end-users are not even able to specify them (they are IT naive) nor pay for professional help to do the job for them. This paper proposes a solution to such a problem. The solution is organized in the form of a university level F/OSS vertical development contest, which involves computer science professors as project leaders and students as ``volunteered{''} programmers. Quality of the produced software is guaranteed by means of contest infrastructure, services, support kits which bring vertical seed code, coding and documentation standards and code reviews by the contest steering committee members. One such contest is being carried out in Brazil with the engagement of 5 universities to gain experience and evaluate contest risks, effectiveness and running processes. Results so far are encouraging having produced an already useful city government application. Results also indicated required adjustments in the technical details and procedures but also high levels of professor and student motivation.

For this reason, this work aims to explore some of the effects of participation in a virtual brand community on consumer behaviour. Design/methodology/approach - The paper proposes the positive effects of participation in a virtual community on both consumer trust and loyalty to the product, brand or organisation around which the community is developed. In addition, it also proposes a positive effect of trust on consumer loyalty. After the validations of measurement scales, the hypotheses are contrasted through structural modelling. Findings - The data, obtained through a web survey using members of several free software virtual communities, show that participation in the activities carried out in a virtual community may foster consumer trust and loyalty to the mutual interest of the community (the free software in this case). In addition, the study also found a positive and significant effect of consumer trust on loyalty. Research limitations/implications - Data were collected thanks to a web survey using Spanish-speaking subjects. Practical implications - The high costs every company has to face in order to get new customers make it increasingly necessary to reinforce the ties established with customers. In this respect, this study has shown that managers may foster consumer trust and loyalty by developing virtual brand communities and promoting consumers' participation in them. Originality/value - Most of the works that are focused on virtual communities have been conducted at the conceptual level.

Furthermore, customers may want to choose their services and compose a package dynamically without paying attention to the billing scheme used. The main premise of this paper is that pre-paid and post-paid billing schemes will merge and customers will use services according to their account balance and credits, as opposed to their billing scheme. The requirement on service providers is to use OSS (Operations Support System) functions and the accompanying information model to support diverse pricing and billing schemes, which is a complex task.

In this article, a simplified framework based on a free scripting language (Lua) is presented.

In revision hip arthroplasty (RHA), establishing the center of rotation (COR) can be technically challenging due to the acetabular bone destruction that is usually present, particularly in severe cases such as Paprosky type II and III defects. The aim of this study was to demonstrate the use of open-source medical image reconstruction software and low-cost 3D anatomical models in pre-surgical planning of RHA. Methods. A total of 10 patients, underwent RHA and were included in the study. Computed tomography (CT) scans were performed for all cases, before surgery and approximately 1 week after the procedure. The reconstruction of CT data, 3D virtual planning of the COR and positioning of acetabular cups, including their inclination and anteversion angles, was carried out using the free open source software platform 3D Slicer. In addition, anatomical models of the pelvis were built on a desktop 3D printer from polylactic acid (PLA). Preoperative and postoperative reconstructed imaging data were compared for each patient, and the position of the acetabular cups as well as the COR were evaluated for each case. Results. Analysis of the pre- and post-op center of rotation position data indicated statistically insignificant differences for the location of the COR on the X-axis (1.5 mm, t = 0.5741, p = 0.5868) with a fairly strong correlation of the results (r = -0.672, p = 0.0982), whilst for the location of the COR in the Y and Z-axes, there was statistical dependence (Y axis, 4.7 mm, t = 3.168 and p = 0.0194; Z axis, 1.9 mm, t = 1.887 and p = 0.1081). A strong correlation for both axes was also observed (Y and Z) (Y-axis, r = 0.9438 and p = 0.0014; Z-axis, r = 0.8829 and p = 0.0084). Analysis of inclination angle values showed a statistically insignificant difference between mean values (3.9 degrees, t = 1.111, p = 0.3092) and a moderate correlation was found between mean values (r = -0.4042, p = 0.3685). Analysis of the anteversion angle showed a statistically insignificant difference between mean values (1.9 degrees, t = 0.8671, p = 0.4192), while a moderate correlation between mean values was found (r = -0.4782, p = 0.2777). Conclusions. Three-dimensional reconstruction software, together with low-cost anatomical models, are very effective tools for pre-surgical planning, which have great potential use in orthopedic surgery, particularly RHA. In up and in- and up and out-type defects, it is essential to establish a new COR and to identify three support points within the revision acetabulum in order to correctly position acetabular cups.}, DOI = {10.3390/diagnostics13152516}, Article-Number = {2516}, EISSN = {2075-4418}, ResearcherID-Numbers = {Andrzejewski, Krzysztof/R-8684-2018 Domzalski, Marcin/M-3523-2016 Komorowski, Piotr/AAG-4344-2020 }, ORCID-Numbers = {Andrzejewski, Krzysztof/0000-0001-9363-4982 Poszepczynski, Jan/0000-0002-5759-807X Domzalski, Marcin/0000-0003-1915-0773 Komorowski, Piotr/0000-0002-4035-7501}, Unique-ID = {WOS:001048569900001}, } @article{ WOS:000375090400005, Author = {Huang, Jian and Lim, Min Yee and Zhao, Baixiao and Shao, Longyi and Lao, Lixing}, Title = {PM2.5 and ash residue from combustion of moxa floss}, Journal = {ACUPUNCTURE IN MEDICINE}, Year = {2016}, Volume = {34}, Number = {2}, Pages = {101-106}, Month = {APR}, Abstract = {Background Moxibustion, a Traditional Chinese Medicine technique, involves burning moxa floss to apply heat to certain points or areas of the body surface to treat disease. Moxibustion releases a considerable amount of smoke into the environment. There remains controversy over the safety of moxa smoke and its potential effects on human health. Methods We measured the PM2.5 (particulate matter with aerodynamic diameter <2.5m) mass concentration in moxa smoke and the oxidative capacity of PM2.5 and moxa ash (using a plasmid scission assay in whole and water-soluble fractions) in the by-products of moxibustion produced from burning moxa floss of different ratios (3:1 or 15:1) and duration of storage (3 or 10years) in three simulated moxibustion clinics. Results PM2.5 mass concentration was 224.28, 226.39 and 210.56g/m(3) for samples A (3years and 3:1 ratio), B (3years and 15:1 ratio), and C (10years and 3:1 ratio), respectively. Average D-500 oxidative damage of PM2.5 was 29.42\%, 29.16\% and 27.01\% and that of moxa ash was 22.78\%, 20.60\% and 21.42\% for samples A, B and C, respectively. PM2.5 demonstrated a significantly greater oxidative capacity than moxa ash (p<0.05). Conclusions The oxidative DNA damage induced by individual PM2.5 following moxibustion was lower than that reported in other environments. However, PM2.5 mass concentration after moxibustion is still relatively high. We would recommend ensuring adequate ventilation during moxibustion to reduce any possible risks. Further studies are needed to better define the potential impact of particles in moxibustion by-products on human health.}, DOI = {10.1136/acupmed-2015-010914}, ISSN = {0964-5284}, EISSN = {1759-9873}, ResearcherID-Numbers = {Lim, Min/H-5696-2016 Lao, Lixing/P-9107-2019 Shao, Longyi/AAS-9317-2020 }, ORCID-Numbers = {Shao, Longyi/0000-0001-9975-6091 Lao, Lixing/0000-0003-0198-9714}, Unique-ID = {WOS:000375090400005}, } @article{ WOS:000742179000014, Author = {Padala, Hema Susmita and Mendez, Christopher and Fronchetti, Felipe and Steinmacher, Igor and Steine-Hanson, Zoe and Hilderbrand, Claudia and Horvath, Amber and Hill, Charles and Simpson, Logan and Burnett, Margaret and Gerosa, Marco and Sarma, Anita}, Title = {How Gender-Biased Tools Shape Newcomer Experiences in OSS Projects}, Journal = {IEEE TRANSACTIONS ON SOFTWARE ENGINEERING}, Year = {2022}, Volume = {48}, Number = {1}, Pages = {241-259}, Month = {JAN 1}, Abstract = {Previous research has revealed that newcomer women are disproportionately affected by gender-biased barriers in open source software (OSS) projects.

In this paper, we investigate that facet of software using a configurable simulation framework as a basis. The framework uses `agents' to represent developers and models the costs associated with first comprehending and then applying necessary changes to a fictitious code base. It also considers agent `memory recall' of their own code as a fundamental part of the framework and the fact that, with higher numbers of developers, maintenance of a higher proportion of other developers' code (rather than their own) is an inevitable, yet realistic aspect. Through exploration of the results and data produced by the simulation. We are able to explore `desirable' features that are part of simulating software evolution; as a discussion of the issues raised by the framework, we provide a set of class data from four open-source systems by way of comparison and show that trends in those systems are comparable with results generated by the simulation.

Clinical use with prostate gold fiducial markers is presented. Methods Projections of regions of interest (ROI) in the reference frame of the electronic portal imaging device are computed offline for different gantry angles before the first treatment fraction. During treatment delivery, the contrast of portal images is automatically adjusted using a histogram equalization algorithm. The projections associated with the current gantry angle are then superimposed on the images in real time. This allows the therapist to evaluate if the imaged structures of interest remain within their respective contours during treatment delivery and to potentially interrupt the treatment if deemed necessary. The spatial accuracy of the method was evaluated by imaging a ball bearing phantom in a set-up where the position of the projected ROI is highly sensitive to gantry angle errors. The visibility of fiducial markers during one fraction of seven different volumetric modulated arc therapy (VMAT) prostate treatments is characterized. Results The geometric validation showed a negligible systematic error mu < 0.1 mm for the position of the projections. The random errors associated with the time accuracy of the gantry angle readout were characterized by standard deviations sigma <= 0.6 mm. The VMAT clinical treatments showed that the fiducial markers were frequently visible, allowing for a meaningful clinical use. Conclusions The results demonstrate that the method presented is sufficiently accurate to be used for intrafraction monitoring of patients. The fact that this method could be implemented on many modern linacs at little to no cost and with no additional dose delivered to the patients makes this solution very attractive for improving patient care and safety in radiation therapy.}, DOI = {10.1002/acm2.12940}, EarlyAccessDate = {JUN 2020}, ISSN = {1526-9914}, ResearcherID-Numbers = {Tremblay, Nicolas/O-7927-2019}, Unique-ID = {WOS:000538292400001}, } @incollection{ WOS:000279571300010, Author = {Bruzzone, Gabriele and Bibuli, Marco and Caccia, Massimo}, Editor = {Hayes, M and Johansen, I}, Title = {A FREE SOFTWARE PLATFORM FOR EMBEDDED REAL-TIME ROBOTICS AND INDUSTRIAL AUTOMATION}, Booktitle = {JAVA SOFTWARE AND EMBEDDED SYSTEMS}, Series = {Computer Science Technology and Applications}, Year = {2010}, Pages = {211-225}, Abstract = {Embedded real-time platforms are a basic component of both robots and machines for the automation of industrial processes.

As a first step towards proposing articulated actions towards diversity and inclusion, we need first to explore the gender gap in terms of activities and interactions.

We particularly focus on building socio-technical networks and analyze them to explain how females contribute and interact in practice. We reflect on interactions' graphs and examine through a preliminary study, using data from six OSS projects, possible links between existing findings and the directions we suggest for more gender diversity.

Two feature that makes them particularly attractive are their interactive nature and easy testing during the model development process. However, they are less suited for operation as production level models due to their slow simulation performance. This paper presents a new extension to the EDD that offers C++ model performance coupled with the convenience of EDD modelling. The extended form of the EDD is called a Verilog-A EDD or VAEDD for short. It has the same structure as the standard EDD but is built around compiled Verilog-A module code, which in turn is translated to C++ code and dynamically linked to the main body of the simulator code. Essentially a VAEDD is a tiny Verilog-A module with a standardised internal code structure.

These platforms are usually centered in a specific brand/product and their members are linked by a shared admiration to that brand. This paper analyzes one of the most powerful online collaborative platforms, the free software (FS) case, which involves a lot of virtual communities developed around products such as Linux or Android, the new Google's mobile operating system. Our purpose is to determine some of the main antecedents and consequences of the consumer involvement in this type of communities. Results have shown that satisfaction with a virtual community may increase the level of consumer participation in that community. At the same time, a greater identification with the virtual community may increase indirectly the consumer participation thanks to the enhancement of his/her satisfaction with the community. We have also found positive and significant effects of consumer identification and participation on the level of community promotion. Finally, positive and significant effects of consumer participation and satisfaction with the community on loyalty to the FS were also found. These findings allow us to conclude some interesting managerial implications. (C) 2010 Elsevier Ltd.

Knowledge can be shared among individuals, groups, and organizations. A free software community is a type of community of practice arranged around a specific free software, where the knowledge shared is complex and the knowledge sharing processes have scarcely been studied. This investigation aims to identify the profiles of knowledge sharing processes in free software communities and examine how 6 motivations for sharing knowledge in free software communities are associated with each of the clusters. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters were identified: Sporadic Sharer; Collector; Donator; and Constant Sharer. With the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators and Collectors. These results confirm the view of free software communities as communities of practice and highlight the importance of knowledge sharing in free software development cycle. The results reveal the importance of the Constant Sharer profile, which has the highest rates of donation and collection and is also the profile in which all the motivations appear with the highest values, indicating its key role in the functioning of free software communities.}, DOI = {10.1002/kpm.1569}, ISSN = {1092-4604}, EISSN = {1099-1441}, ResearcherID-Numbers = {Oliveira, Mirian/IZQ-0495-2023 Balle, Andrea/O-7855-2016 Oliveira, Mirian/B-5090-2010 }, ORCID-Numbers = {Oliveira, Mirian/0000-0002-5498-0329 Balle, Andrea/0000-0003-2521-5342}, Unique-ID = {WOS:000440654200002}, } @inproceedings{ WOS:000426465900026, Author = {Fu, Chenbo and Zhou, Mingming and Xuan, Qi and Hu, Hong-Xiang}, Book-Group-Author = {IEEE}, Title = {Expert Recommendation in OSS Projects Based on Knowledge Embedding}, Booktitle = {2017 14TH INTERNATIONAL WORKSHOP ON COMPLEX SYSTEMS AND NETWORKS (IWCSN)}, Year = {2017}, Pages = {149-155}, Note = {14th International Workshop on Complex Systems and Networks (IWCSN), Doha, QATAR, DEC 08-10, 2017}, Organization = {IEEE Circuits \& Syst Soc; Texas A \& M Univ Qatar; City Univ Hong Kong}, Abstract = {Modern Open Source Software (OSS) projects depend on the globally-distributed and synchronized software development.

Understanding how developers become inactive or why they take breaks can help communities prevent abandonment and incentivize developers to come back. In this paper, we propose a novel method to identify developers' inactive periods by analyzing the individual rhythm of contributions to the projects. Using this method, we quantitatively analyze the inactivity of core developers in 18 OSS organizations hosted on GitHub. We also survey core developers to receive their feedback about the identified breaks and transitions. Our results show that our method was effective for identifying developers' breaks. About 94\% of the surveyed core developers agreed with our state model of inactivity; 71\% and 79\% of them acknowledged their breaks and state transition, respectively. We also show that all core developers take breaks (at least once) and about a half of them (similar to 45\%) have completely disengaged from a project for at least one year. We also analyzed the probability of transitions to/from inactivity and found that developers who puce their activity have a similar to 35 to similar to 55\% chance to return to an active state; yet, if the break lasts for a year or longer, then the probability of resuming activities drops to similar to 21-26\%, with a similar to 54\% chance of complete disengagement. These results may support the creation of policies and mechanisms to make OSS community managers aware of breaks and potential project abandonment.}, DOI = {10.1007/s10664-021-10012-6}, Article-Number = {76}, ISSN = {1382-3256}, EISSN = {1573-7616}, ResearcherID-Numbers = {Gerosa, Marco/A-6686-2009 Lanubile, Filippo/AAF-9132-2020 Igor, Steinmacher/B-6414-2012 Calefato, Fabio/H-4177-2014 }, ORCID-Numbers = {Calefato, Fabio/0000-0003-2654-1588 Gerosa, Marco/0000-0003-1399-7535}, Unique-ID = {WOS:000770762600001}, } @inproceedings{ WOS:000625294907095, Author = {Mueller, Matthias and Schindler, Christian and Slany, Wolfgang}, Editor = {Bui, TX}, Title = {Engaging Students in Open Source: Establishing FOSS Development at a University}, Booktitle = {PROCEEDINGS OF THE 52ND ANNUAL HAWAII INTERNATIONAL CONFERENCE ON SYSTEM SCIENCES}, Year = {2019}, Pages = {7721-7730}, Note = {52ndHawaii International Conference on System Sciences (HICSS), HI, JAN 08-11, 2019}, Abstract = {Open source is widely used for educational purposes in higher education around the world.

However, the use of these tools for education purposes faces important barriers: the availability of the resources, the cost and the students' perception, among many others. These problems might be overcome by the use of free software simulators. In this paper, we present several experiences using free software tools in engineering Higher Education courses. The experiences shown cover several courses of different engineering Degrees: ``Electronics and Automation{''}, ``Electrical Engineering{''}, ``Computing{''} and ``Industrial Technologies{''}. These tools have been used in teaching activities for several years. As a result, the perceptions, gained experience and views of the teachers involved in the different courses are presented and discussed. Teachers specially valued the independence of the tools from commercial policies, as well as the suppression of expensive licenses. Additionally, they perceived that students understood better the simulations performed since all the parts of the tools could be freely accessed. They also remarked the possibility of changing the code at low level and fuse different free software projects together, what is not possible with the commercial tools. In addition, free software resources allowed students to start in a very common world currently, the collaborative communities, which may be of great importance in their future professional activities. However, teachers involved in these experiences also detected several drawbacks. In some cases, free software simulators are less robust than their commercial alternatives, which usually pay special attention at the design, being perceived by students as a signal of higher quality. In some simulators the documentation is incomplete, and there is a lack of easy-to-use examples which hinders the use of the tool by low-experienced users such as first-year students. The opportunities and threats faced by these tools are also discussed, concluding that when selecting an educational resource, the free software resources must be considered as perfectly valid options in the same conditions as the proprietary solutions.}, ISSN = {2340-1117}, ISBN = {978-84-608-8860-4}, ResearcherID-Numbers = {Arcega, Francisco/AAG-8003-2020 García-Magariño, Iván/C-9189-2011}, Unique-ID = {WOS:000402955908095}, } @incollection{ WOS:000553241100006, Author = {Depoorter, Gael}, Editor = {Frere, B and Jacquemain, M}, Title = {The Free Software Community: A Contemporary Space for Reconfiguring Struggles?}, Booktitle = {EVERYDAY RESISTANCE: FRENCH ACTIVISM IN THE 21ST CENTURY}, Year = {2020}, Pages = {117-143}, DOI = {10.1007/978-3-030-18987-7\_6}, ISBN = {978-3-030-18987-7; 978-3-030-18986-0}, Unique-ID = {WOS:000553241100006}, } @inproceedings{ WOS:000380425100003, Author = {Hata, Hideaki and Todo, Taiki and Onoue, Saya and Matsumoto, Kenichi}, Book-Group-Author = {IEEE}, Title = {Characteristics of Sustainable OSS Projects: A Theoretical and Empirical Study}, Booktitle = {2015 IEEE/ACM 8TH INTERNATIONAL WORKSHOP ON COOPERATIVE AND HUMAN ASPECTS OF SOFTWARE ENGINEERING CHASE 2015}, Year = {2015}, Pages = {15-21}, Note = {8th IEEE/ACM International Workshop on Cooperative and Human Aspects of Software Engineering (CHASE), Florence, ITALY, MAY 18-18, 2015}, Organization = {IEEE COMP SOC; TCSE; ACM; SIGSOFT}, Abstract = {How can we attract developers?

Based on these results, we again analyzed the projects empirically to support the outcome of the models, and found empirical evidence. The answers to the initial questions are clear.

In this work, we describe the Hybrid Overlap Filter (HyOF), a new filtering algorithm implemented in the free R software environment. The flow diagram of HyOF differs in the following ways from that of other filters developed to date: (1) the algorithm is formed by a combination of sequentially operating functions (i.e., the output of the first function provides the input of the second), which are capable of functioning independently and thus enabling integration of these functions with other filtering algorithms; (2) the variable penetrability is defined and used, along with slope and elevation, to identify ground points; (3) prior to selection of the seed points, the original point cloud is processed with the aim of removing points corresponding to buildings; and (4) a new method based on a moving window, with longitudinal overlap between windows and transverse overlap between passes, is used to select the seed points. Our hybrid filtering method is tested using 15 reference samples acquired by the International Society of Photogrammetry and Remote Sensing (ISPRS) and is evaluated in comparison with 33 existing filtering algorithms. The results show that our hybrid filtering method produces an average total error of 3.34\% and an average Kappa coefficient of 92.62\%.

This process finds the best matching case and recommended measures by intuitionistic fuzzy rough sets. To verify the model, Kunming Lake and other 20 lakes are simulated with the proposed method.

Describe that the experiments were conducted using widely recognized brands of pork floss available in the grocery market, omitting the use of abbreviations. A total of 8000 images of eight commercially available pork flosses were collected and processed using sharpening, image gray coloring, real-time shading correction, and binarization. After the machine learning model learned the features of the pork floss, the images were labeled using a manual mask. The coupling of residual enhancement mask and region-based convolutional neural network (CRE-MRCNN) based deep learning framework was used to segment the images. The results showed that CRE-MRCNN could be used to identify the knot features and pore features of different brands of pork floss to evaluate their quality. The combined results of the models based on the sensory tests and machine vision showed that the pork floss from TC was the best, followed by YJJ, DD and HQ.

Such analyses have the objective of evaluating effort, productivity and types of activity globally and around major releases. They enable a comparison of these releases and patterns of effort and activities with traditional software products and processes, and in turn, the identification of company-driven projects (i.e., working mainly during office hours) among FLOSS endeavors. The results of this research show that, overall, the effort within the Linux kernel community is constant (albeit at different levels) throughout the week, signalling the need of updated estimation models, different from those used in traditional 9am-5pm, Monday to Friday commercial companies. It also becomes evident that the activity before a release is vastly different from after a release, and that the changes show an increase in code complexity in specific time slots (notably in the late night hours), which will later require additional maintenance efforts.}, DOI = {10.1007/s10664-011-9191-7}, ISSN = {1382-3256}, EISSN = {1573-7616}, ResearcherID-Numbers = {Capiluppi, Andrea/AGO-2961-2022 Cortazar, Daniel/ABE-2382-2020 }, ORCID-Numbers = {Capiluppi, Andrea/0000-0001-9469-6050}, Unique-ID = {WOS:000313069300003}, } @article{ WOS:000447349200007, Author = {Nestor, Pauline}, Title = {ETHICAL EVOLUTION: ENDOGAMY AND EXOGAMY IN THE MILL ON THE FLOSS}, Journal = {GEORGE ELIOT-GEORGE HENRY LEWES STUDIES}, Year = {2007}, Number = {52-53}, Pages = {93-104}, Month = {SEP}, ISSN = {2372-191X}, Unique-ID = {WOS:000447349200007}, } @article{ WOS:000290470500004, Author = {Chou, Shih-Wei and He, Mong-Young}, Title = {Understanding OSS development in communities: the perspectives of ideology and knowledge sharing}, Journal = {BEHAVIOUR \& INFORMATION TECHNOLOGY}, Year = {2011}, Volume = {30}, Number = {3}, Pages = {325-337}, Abstract = {This study aims to understand why open source software (OSS) developers contribute and how their dispersed efforts are controlled to lead to viable outputs.

In this article, the bug closure process that is followed by a community of an open source software project is investigated in order to perform process conformance checking. Actual data that reveal the process steps have been extracted from the project's Bugzilla database and have been used as input in Disco process mining tool. The data includes extracted information for more than 19,000 bugs for the past 15 years in a csv form, formatted appropriately to construct an event log suitable for process mining. The extracted models have been compared to the process described in the project's blogs and wikis by the community. The same models are also compared to the bug closure process that Bugzilla suggests to be used by the projects using this software for bug tracking purposes. The findings reveal that indeed the process followed in the OSS project is very similar to the declared one but variations do occur under specific circumstances. However, the process is not identical to the one proposed by Bugzilla suggesting that each OSS project can customize its processes in order to better address the needs of the project and the community.

A methodology to integrate GIS and statistics in morphometric analysis is presented for the most usual morphometric parameters-hypsometry, slope, aspect, swath profiles, lineaments and drainage density, surface roughness, isobase and hydraulic gradient. The GIS used was the Geographic Resources Analysis Support System (GRASS-GIS), an open-source project that offers an integrated environment for raster and vector analysis, image processing and maps/graphics creation. Statistical analysis of parameters can be carried out on R, a system for statistical computation and graphics, through an interface with GRASS that allows raster maps and points files to be treated as variables for analysis. The basic element for deriving morphometric maps is the digital elevation model (DEM). It can be interpolated from scattered points or contours, either in raster or vector format; it is also possible to use DEMs from NASA's Shuttle Radar Topographic Mission, with 30 m of ground resolution for the USA and 90 m for other countries. Proposed methodology can be adapted according to necessities and available tools. The use of free and open-source tools guarantees access to everyone, and its increasing popularization opens new development perspectives in this research field. (C) 2004 Elsevier Ltd.

Currently, FAQ chatbot is the most popular domain of use of dialog assistants. However, developing a chatbot project requires a full-stack team formed by numerous specialists, such as dialog designer, data scientist, software engineer, DevOps, business strategist and experts from the domain, which can be both time and resources consuming. Language processing can be particularly challenging in languages other than English due to the scarcity of training datasets. Most of the requirements of FAQ chatbots are similar, domain-specific, and projects could profit from Open Source Software (OSS) reuse. In this paper, we examine how OSS FAQ chatbot projects can benefit from reuse at the project level (black-box reuse). We present an experience report of a FLOSS FAQ chatbot project developed in Portuguese to an e-government service in Brazil. It comprises of the chatbot distribution service, as well as for analytics tool integrated and deployed on-premises. We identified assets that could be reused as a black-box and the assets that should be customized for a particular application. We categorized these assets in architecture, corpus, dialog flows, machine learning models, and documentation. This paper discusses how automation, pre-configuration, and templates can aid newcomers to develop chatbots in Portuguese without the need for specialized skills required from tools in chatbot architecture. Our main contribution is to highlight the issues non-English FAQ chatbots projects will likely face and the assets that can be reused. It allows non-chatbot experts to develop a quality-assured OSS FAQ chatbot in a shorter project cycle.}, DOI = {10.1145/3306446.3340823}, ISBN = {978-1-4503-6319-8}, Unique-ID = {WOS:000632588700003}, } @inproceedings{ WOS:000368495600006, Author = {Blincoe, Kelly and Damian, Daniela}, Editor = {Damiani, E and Frati, F and Riehle, D and Wasserman, AI}, Title = {Implicit Coordination: A Case Study of the Rails OSS Project}, Booktitle = {OPEN SOURCE SYSTEMS: ADOPTION AND IMPACT}, Series = {IFIP Advances in Information and Communication Technology}, Year = {2015}, Volume = {451}, Pages = {35-44}, Note = {11th IFIP WG 2.13 Annual International Conference on Open Source Systems (OSS), Florence, ITALY, MAY 16-17, 2015}, Organization = {IFIP WG 2 13; Google}, Abstract = {Previous studies on coordination in OSS projects have studied explicit communication.

The evaluation and comparison of more than one examination is time-consuming and prone to create errors. Using the free software environment R we developed a solution to average the data of multiple examinations and to allow a comparison of different patient groups. Methods: Data of single mfERG recordings as exported in .csv format from a RETIport 21 system (version 7/03, Roland Consult) or manually compiled .csv files are the basis for the calculations. The R software extracts response densities and implicit times of N1 and P1 for the sum response, each ring eccentricity, and each single hexagon. Averages can be calculated for as many subjects as needed. The mentioned parameters can then be compared to another group of patients or healthy subjects. Application of the software is illustrated by comparing 11 patients with chloroquine maculopathy to a control group of 7 healthy subjects. Results: The software scripts display response density and implicit time 3D plots of each examination as well as of the group averages. Differences of the group averages are presented as 3D and grayscale 2D plots. Both groups are compared using the t-test with Bonferroni correction. The group comparison is furthermore illustrated by the average waveforms and by boxplots of each eccentricity.

This study shows that entrepreneurs differentiate themselves from non-entrepreneurs by focusing on cognitive and relational capital building activities, which in return makes it possible for them to leverage their social capital to influence and shape the environment in which they are operating. Our findings suggest that entrepreneurs strategically select which activities within the community to expend their limited resources on (e.g., developing code over participating in email conversations) and build their social capital more through their actions than through their words (e.g., showing their commitment to the community through code commits, bug fixes, and documentation).

This paper studies (i) types of modifications that may affect vulnerable open-source dependencies and (ii) their impact on the performance of vulnerability scanners. Through an empirical study on 7,024 Java projects developed at SAP, we identified four types of modifications: re-compilation, re-bundling, metadata-removal and re-packaging. In particular, we found that more than 87 percent (56 percent, resp.) of the vulnerable Java classes considered occur in Maven Central in re-bundled (re-packaged, resp.) form. We assessed the impact of these modifications on the performance of the open-source vulnerability scanners OWASP Dependency-Check (OWASP) and Eclipse Steady, GitHub Security Alerts, and three commercial scanners. The results show that none of the scanners is able to handle all the types of modifications identified.

The OSS technique allows for the rapid calculation of radiance for any class of multispectral, hyperspectral, or ultraspectral sensors at any spectral resolution operating in any region from microwave through UV wavelengths by selecting and appropriately weighting the monochromatic points that contribute over the sensor bandwidth. This allows for the calculation to be performed at a small number of spectral points while retaining the advantages of a monochromatic calculation such as exact treatment of multiple scattering and/or polarization. The OSS method is well suited for remote sensing applications which require extremely fast and accurate radiative transfer calculations: atmospheric compensation, spectral and spatial feature extraction, multi-sensor data fusion, sub-pixel spectral analysis, qualitative and quantitative spectral analysis, sensor design and data assimilation.

The social and technical activities of developers evolve together, and as they link to each other they get organized in a network of changing socio-technical connections. Traces of those activities, or behaviors, are typically visible to all, in project repositories and through communication between them. Thus, in principle it may be possible to study those traces to tell which of the observable socio-technical behaviors of developers in these projects are responsible for the forming of persistent links between them. It may also be possible to tell the extent to which links participate in the spread of potential behavioral influences. Since OSS projects change in both social and technical activity over time, static approaches, that either ignore time or simplify it to a few slices, are frequently inadequate to study these networks. On the other hand, ad-hoc dynamic approaches are often only loosely supported by theory and can yield misleading findings. Here we adapt the stochastic actor-oriented models from social network analysis. These models enable the study of the interplay between behavior, influence and network architecture, for dynamic networks, in a statistically sound way. We apply the stochastic actor-oriented models in case studies of two Apache Software Foundation projects, and study code ownership and developer productivity as behaviors. For those, we find evidence of significant social selection effects (homophily) in both projects, but in different directions. However, we find no evidence for the spread (social influence) of either code ownership or developer productivity behaviors through the networks.}, DOI = {10.1007/s10664-016-9431-y}, ISSN = {1382-3256}, EISSN = {1573-7616}, Unique-ID = {WOS:000392378400011}, } @inproceedings{ WOS:000380608000003, Author = {Tansho, Terutaka and Noda, Tetsuo}, Book-Group-Author = {ACM}, Title = {Utilization and Development Contribution of Open Source Software in Japanese IT Companies: An Exploratory Study of the Effect on Business Growth (2nd report based on 2014 survey)}, Booktitle = {Proceedings of the 11th International Symposium on Open Collaboration}, Year = {2015}, Pages = {A3+}, Note = {11th International Symposium on Open Collaboration, San Francisco, CA, AUG 19-21, 2015}, Organization = {Wikimedia Fdn; Google Inc; Univ California Berkeley; ACM SIGSOFT; ACM SIGWEB; John Ernest Fdn}, Abstract = {The usage of Open Source Software (OSS) has been extended in a wide range of business fields not only IT industries.

However, in textbooks molecular structures are represented as two-dimensional objects and as result, students might find difficult to switch from 2D to 3D structures or images. Using 3 dimensional models help students acquire a better understanding of molecular geometry and encourage active learning. Computer visualizations now offer an interesting possible alternative to concrete or physical models {[}3]. Jmol is one of the most prevalent molecular visualization tools in STEM education. It is a free open source software for interactive molecular visualization. This work describes the implementation of the Jmol visualization tool in a module on General Chemistry for Engineers during the academic year 2016-2017. The goals were three-fold. Firstly, to use the Jmol visualization application as a teaching tool for classroom demonstration. Then, to provide students with the skills to use the molecular visualization tool for their own learning process. Finally, to actively engage students with generation and manipulation of molecular models. Jmol application was used during Lectures to teach about molecular structure. Students then had to download and use the application on their own to complete several worksheets. Later on, Jmol molecular models were also used to aid student understanding of organic chemistry, including isomerism. Additional worksheets and assignments involved the use of Jmol visualization tool. The evaluation of the software implementation on the module was carried out by marking the worksheets and by a survey that was conducted among the students.}, ISSN = {2340-1117}, ISBN = {978-84-697-3777-4}, Unique-ID = {WOS:000493048104068}, } @article{ WOS:000421470000014, Author = {Serna Montoya, Edgar and Andres Galvis, Jorge and Mauricio Ortiz, Ivan}, Title = {Strategic Principles of Free Software and its Relation with Process Reengineering}, Journal = {REVISTA VIRTUAL UNIVERSIDAD CATOLICA DEL NORTE}, Year = {2014}, Volume = {42}, Pages = {197-206}, Month = {MAY-AUG}, Abstract = {In the last decades, companies have been forced to restructure their processes to remain competitive in a globalized world.

In this work we describe some strategies based on free software which can be applied in process reengineering to achieve this goal.

Early on it was decided to use one software system to run our simulations as well as ultimately handle the event processing for real data. We leveraged many existing HEP external libraries (Geant4, Gaudi Framework, ROOT, CLHEP, CMT) to ease the burden on our developers. This strategy of re-using existing software helped us pull together our system quickly and test during our beam tests and data challenges. Now, after launch, we are in a new phase of the project, where we must move forward to support modern operating systems and compilers to get us through the life of the mission. This means upgrading our external libraries as well, which are not under our direct control. Meanwhile, it is crucial to our production system that we carefully orchestrate all upgrades to insure stability. An additional hurtle is that our number of active developers has dwindled dramatically.

Our findings indicate that gender diversity is low across all parts of the world, with no substantial difference across regions. However, there has been statistically significant improvement in diversity worldwide since 2014, with certain regions such as Africa improving at faster pace. We also find that most motivations and barriers to contributions (e.g., lack of resources to contribute and poor working environment) were shared across regions, however, some insightful differences, such as how to make projects more inclusive, did arise.

The author demonstrate ``Das Flog der Medusa{''} like a example of the protest music as a direction that exposes not only fascism, but also any form of social inequality, violence against the person. The study of the features of choral style of ``Das Flog der Medusa{''} reveals parallels in the textural structure between Henze's oratorio and Nono's works of the 1950s ({''}La victoire de Guernica{''}, ``Il canto sospeso{''}, ``Intolleranza 1960{''}). The use of political text resources, the operation of individual syllables and phonemes of a literary text, work with multilingual verbal rows, the active use of diagonal texture - all this brings together the choral works of two contemporaries. At the same time, Henze's composition also reflected the searches in the field of vocal timbre, characteristic of other composers of Darmstadt Summer Course - the use of various modifications of speech singing ( Sprech- gesang ), the latest techniques of vocal articulation (vocal tremolo, prolongation of the anterolingual vibrant). All this together allows us to talk about Henz's oratorio as one of the most peculiar choral compositions of the late 1960s.}, DOI = {10.21638/spbu15.2024.102}, ISSN = {2221-3007}, EISSN = {2542-2243}, Unique-ID = {WOS:001238177200002}, } @article{ WOS:000367946100020, Author = {Remmel, Tarmo K.}, Title = {ShrinkShape2: A FOSS toolbox for computing rotation-invariant shape spectra for characterizing and comparing polygons}, Journal = {CANADIAN GEOGRAPHIES-GEOGRAPHIES CANADIENNES}, Year = {2015}, Volume = {59}, Number = {4}, Pages = {532-547}, Month = {WIN}, Abstract = {Delineation of geographic space partitions landscapes into regions that express relative homogeneity within those delineated regions and many efforts exist to analyze the resulting shapes that these delineations produce.

This free, efficient, and accessible environment provides a multidimensional, rotation invariant, scale-controlled method for characterizing and comparing planar shapes and tools for visualizing results. ShrinkShape2 incrementally buffers polygons internally until the point of extinction; at each shrinking phase a series of summary metrics are computed to form spectra of index values that characterize general characteristics of shape structure and complexity. Demonstrations with simple synthetic shapes, political boundary maps, and a sample sub-Arctic pond demonstrate the ability to assess boundary complexity, pinch-points, and identify holes within larger shapes. For perfectly convex and compact shapes, perimeter decompositions will decrease linearly and area decompositions will decrease according to one limb of a second-order polynomial function relative to the cumulative shrinking distance.

By mining the repositories of 6 open source projects, we characterize the differences in the fixing process between vulnerabilities and canonical bugs, highlighting critical issues which could represent challenges for future research. Results of our study demonstrate that: (i) more re-assignments (than the ones observed in canonical bugs) are required for finding the developers able to handle vulnerability-related bugs, (ii) developers' security-related skills should be profiled, to improve the efficiency of the security bug assignment tasks, and, consequently, reduce the re-assignments, and (iii) vulnerabilities require more effort, contributors and time to define the fixing strategy but smaller time to fix than canonical bugs.

The study uncovered specific aspects related to trust and trustworthiness of the Open Source Software development process that we did not find in previous studies as: the standards implemented by the OSS project, the project's roadmap is respected, and the communication channels that are available.}, ISSN = {1868-4238}, EISSN = {1868-422X}, ISBN = {978-3-642-24418-6; 978-3-642-24417-9}, ResearcherID-Numbers = {Succi, Giancarlo/AAZ-2354-2020}, Unique-ID = {WOS:000309430500016}, } @article{ WOS:000323497400005, Author = {Schiaffino, Chiara F. and Brignone, Massimo and Ferrari, Marco}, Title = {A free software for sand and gravel embayed beach modelling: PhoEbuS- parabolic equation shape}, Journal = {EARTH SCIENCE INFORMATICS}, Year = {2013}, Volume = {6}, Number = {3}, Pages = {165-173}, Month = {SEP}, Abstract = {An in-depth knowledge of the littoral system is essential for its conservation and for an accurate planning of due interventions. The parabolic bay shape equation, used to study the embayed beach planform, is a qualitatively assessed instrument to obtain information about beach equilibrium conditions. Nowadays the equation has been extended in order to be applicable not only to sand beaches but also to gravel beaches. In this paper Phoebus user-friendly software for an automatic use of the extended parabolic bay shape equation is presented. The software enables both technical experts and non-professionals to conduct expeditious analysis in order to evaluate the evolution and equilibrium conditions of embayed littoral beaches lying between natural headlands or man-made structures, as well as to artificially recreate stable embayed beaches by building new artificial structures on open beaches. The software can be also used for coastal planning, to anticipate beach modifications in response to new building or to changes in pre-existing structures. Highlights 1. Development of a free software to automatically compute embayed beach planform 2. The system can be used on every type of beach image 3. The software allows to display the planform both for sand and gravel beaches 4.

Typically, the developers create a stable branch for each old stable version, deploy security patches on the branch, and release fixed versions at regular intervals. As such, old-version applications in production environments are protected from the disclosed vulnerabilities in a long time. However, the rapidly growing number of OSS vulnerabilities has greatly strained this patch deployment model, and a critical need has arisen for the security community to understand the practice of security patch management across stable branches. In this work, we conduct a large-scale empirical study of stable branches in OSS projects and the security patches deployed on them via investigating 608 stable branches belonging to 26 popular OSS projects as well as more than 2,000 security fixes for 806 CVEs deployed on stable branches. Our study distills several important findings: (i) more than 80\% affected CVE-Branch pairs are unpatched; (ii) the unpatched vulnerabilities could pose a serious security risk to applications in use, with 47.39\% of them achieving a CVSS score over 7 (High or Critical Severity); and (iii) the patch porting process requires great manual efforts and takes an average of 40.46 days, significantly extending the time window for N-day vulnerability attacks. Our results reveal the worrying state of security patch management across stable branches. We hope our study can shed some light on improving the practice of patch management in OSS projects.}, DOI = {10.1145/3485447.3512236}, ISBN = {978-1-4503-9096-5}, Unique-ID = {WOS:000852713000077}, } @article{ WOS:000229256600003, Author = {Mayer, J}, Title = {Network management and OSS: Todays lean operators, tomorrow's market leaders}, Journal = {ALCATEL TELECOMMUNICATIONS REVIEW}, Year = {2003}, Number = {3}, Pages = {176-181}, ISSN = {1267-7167}, Unique-ID = {WOS:000229256600003}, } @inproceedings{ WOS:000360571700108, Author = {Kuwata, Yoshitaka and Miura, Hiroshi}, Editor = {Ding, L and Pang, C and Kew, LM and Jain, LC and Howlett, RJ}, Title = {A Study on Growth Model of OSS Projects to estimate the stage of lifecycle}, Booktitle = {KNOWLEDGE-BASED AND INTELLIGENT INFORMATION \& ENGINEERING SYSTEMS 19TH ANNUAL CONFERENCE, KES-2015}, Series = {Procedia Computer Science}, Year = {2015}, Volume = {60}, Pages = {1004-1013}, Note = {19th International Conference on Knowledge Based and Intelligent Information and Engineering Systems (KES), Singapore, SINGAPORE, SEP 07-09, 2015}, Organization = {Natl Univ Singapore, Inst Syst Sci; KES Int}, Abstract = {The products of Open Source Software (OSS) projects are widely used even in commercial mission-critical and high-availability systems. This is because both the quality of these software products is high enough for these applications and the support of software could fulfill the requirement. In general, when one wants to adopt OSS as a part of computer systems, it is required to examine the functional requirement (FR) for the OSS as well as nonfunctional requirement (NFR). In the previous paper, we focused on NFR of OSS and proposed an evaluation method based on the maturity model of OSS community. Based on the model, we tried to evaluate four major OSS communities. For the evaluation, we used human knowledge of targeted OSS community. However it was not clear how to evaluate individual OSS project in OSS community. In this paper, we focused on continuity of OSS project, as it is one of the most important factors for users to make a decision. In order to evaluate continuity, we proposed a growth model of OSS project, which is based on the size and activity of OSS Project. We evaluated the growth model using information retrieved from OSS communities from both OSS community sites and source code repositories. (C) 2015 The Authors.

To capture user innovation and to maintain quality of software and productivity of teams, these projects need to attract and retain contributors. Aim: We want to understand and quantify how inflow and retention are shaped by policies and actions of companies in three application server projects. Method: We identified three hybrid projects implementing the same JavaEE specification and used published literature, online materials, and interviews to quantify actions and policies companies used to get involved. We collected project repository data, analyzed affiliation history of project participants, and used generalized linear models and survival analysis to measure contributor inflow and retention. Results: We identified coherent groups of policies and actions undertaken by sponsoring companies as three models of community involvement and quantified tradeoffs between the inflow and retention each model provides. We found that full control mechanisms and high intensity of commercial involvement were associated with a decrease of external inflow and with improved retention. However, a shared control mechanism was associated with increased external inflow contemporaneously with the increase of commercial involvement. Implications: Inspired by a natural experiment, our methods enabled us to quantify aspects of the balance between community and private interests in open-source software projects and provide clear implications for the structure of future open-source communities.}, DOI = {10.1145/2876443}, Article-Number = {13}, ISSN = {1049-331X}, EISSN = {1557-7392}, ResearcherID-Numbers = {Zhang, Lejie/ACD-9278-2022 Mockus, Audris/AEY-3361-2022 Hong, Mei/IZQ-2897-2023 }, ORCID-Numbers = {Mockus, Audris/0000-0002-7987-7598}, Unique-ID = {WOS:000377289000003}, } @article{ WOS:000233123600033, Author = {{[}Anonymous]}, Title = {Arcelor House, Saint-Maur-des-Fosses - Energetic performances and environmental qualities (Pascal Bonaud)}, Journal = {ARCHITECTURE D AUJOURD HUI}, Year = {2005}, Volume = {360}, Pages = {120}, Month = {SEP-OCT}, ISSN = {0003-8695}, Unique-ID = {WOS:000233123600033}, } @inproceedings{ WOS:000332765100096, Author = {Yang, Xin and Kula, Raula Gaikovina and Erika, Camargo Cruz Ana and Yoshida, Norihiro and Hamasaki, Kazuki and Fujiwara, Kenji and Iida, Hajimu}, Editor = {Leung, KRPH and Muenchaisri, P}, Title = {Understanding OSS Peer Review Roles in Peer Review Social Network (PeRSoN)}, Booktitle = {2012 19TH ASIA-PACIFIC SOFTWARE ENGINEERING CONFERENCE (APSEC), VOL 1}, Series = {Asia-Pacific Software Engineering Conference}, Year = {2012}, Pages = {709-712}, Note = {19th Asia-Pacific Software Engineering Conference (APSEC), Hong Kong, PEOPLES R CHINA, DEC 04-07, 2012}, Organization = {IEEE Hong Kong Sect Comp Soc Chapter; ACM Hong Kong Chapter; IEEE Comp Soc}, Abstract = {Due to the distributed collaborations and the volunteering nature of Open Source Software (OSS), OSS peer review processes differs from traditional approaches.

We contend that increased network centrality and closure among current adopters contribute positively to adoption, whereas the same among potential adopters has exactly the opposite impact. Accordingly, we propose a dynamic view where the fraction of current adopters in the network positively moderates the impact of network centrality and closure.

Some of these species are transient and show a three-year cycle of species replacement (turnover when related to added species).

The corresponding model extends a recent optimization procedure introduced to describe flame propagation in heterogeneous media featuring composition variations (equivalence ratio and temperature) in the fresh reactants or containing residual burned gases (RBG). It is based on the use of an optimized virtual species and a tabulation of the pre-exponential coefficient of an Arrhenius law. The main results of high activation energy asymptotics (AEA) are first recalled to put in evidence the key parameters and the dependence of the ignition delay on the corresponding quantities. The optimization procedure is then applied to these parameters, namely, the pre-exponential factor K and the activation energy E-a of the associated single-step Arrhenius law. An efficient tabulation method benefiting from both rapid access and low storage is proposed for the composition variable (the mixture fraction, in the present case). Finally, the restitution of both ignition and propagation features is ensured through the consideration of the cross-over temperature. The performance of the resulting model is then assessed through comparisons with data obtained from detailed chemistry computations used as reference in several conditions of increasing complexity.

The method starts by randomly fragmenting a BAG, YAC or PAC to 8-12 kb pieces and subcloning those into lambda phage. Insert-ends of these clones are sequenced and overlapped to create a partial map. Complete sequencing is then done on a minimal tiling path of selected subclones, recursively focusing on those at the edges of contigs to facilitate mergers of clones across the entire target. To reduce manual labor, PCR processes have been adapted to prepare sequencing templates throughout the entire operation. The streamlined process can thus lend itself to further automation. The OSS approach is suitable for large-scale genomic sequencing, providing considerable flexibility in the choice of subclones or regions for more or less intensive sequencing. For example, subclones containing contaminating host cell DNA or cloning vector can be recognized and ignored with minimal sequencing effort; regions overlapping a neighboring clone already sequenced need not be redone; and segments containing tandem repeats or long repetitive sequences can be spotted early on and targeted for additional attention.}, DOI = {10.1117/12.274362}, ISBN = {0-8194-2396-3}, Unique-ID = {WOS:A1997BH88N00003}, } @inproceedings{ WOS:000368495600007, Author = {Squire, Megan and Smith, Amber K.}, Editor = {Damiani, E and Frati, F and Riehle, D and Wasserman, AI}, Title = {The Diffusion of Pastebin Tools to Enhance Communication in FLOSS Mailing Lists}, Booktitle = {OPEN SOURCE SYSTEMS: ADOPTION AND IMPACT}, Series = {IFIP Advances in Information and Communication Technology}, Year = {2015}, Volume = {451}, Pages = {45-57}, Note = {11th IFIP WG 2.13 Annual International Conference on Open Source Systems (OSS), Florence, ITALY, MAY 16-17, 2015}, Organization = {IFIP WG 2 13; Google}, Abstract = {This paper describes how software developers who use mailing lists to communicate reacted and adjusted to a new supplementary collaboration tool, called a pastebin service.

We then compare the individual pastebin services and their rates of adoption, as well as the reaction of different communities to the new tools and the various rationales for accepting or rejecting them.}, DOI = {10.1007/978-3-319-17837-0\_5}, ISSN = {1868-4238}, EISSN = {1868-422X}, ISBN = {978-3-319-17837-0; 978-3-319-17836-3}, Unique-ID = {WOS:000368495600007}, } @inproceedings{ WOS:000381005000002, Author = {Schilling, Andreas and Laumer, Sven and Weitzel, Tim}, Book-Group-Author = {ACM}, Title = {Stars Matter - How FLOSS Developers' Reputation Affects the Attraction of New Developers}, Booktitle = {SIGMIS-CPR'14: PROCEEDINGS OF THE 2014 CONFERENCE ON COMPUTERS AND PEOPLE RESEARCH}, Year = {2014}, Pages = {5-10}, Note = {52nd Association-of-Computing-Machinery Annual Conference on Computers and People Research (ACM SIGMIS CPR), Singapore, SINGAPORE, MAY 29-31, 2014}, Organization = {ACM SIGMIS; Assoc Comp Machinery}, Abstract = {The attraction of new developers is a key challenge for initiatives developing Free Libre Open Source Software (FLOSS). While previous evaluations consider status gains and competence evaluations to be key drivers for novices' joining behavior, it is unclear how FLOSS developers' relationships with others affect the attraction of new developers. In this research, we look at FLOSS developers' relationships in terms of positive evaluations given by others. Using this perspective, we examine how FLOSS developers' reputation among members within and beyond the project community affects their projects' ability to attract new developers. We draw on Social Resource Theory (SRT) and hypothesize that developers with a high reputation among others enjoy high visibility and credibility, which in turn helps their projects to attract new members. Finally, we propose an evaluation approach for our research model that examines the reputation and project behavior of more than 1,000 FLOSS developers on a longitudinal base.}, DOI = {10.1145/2599990.2599991}, ISBN = {978-1-4503-2625-4}, ResearcherID-Numbers = {Weitzel, Tim/AFS-7648-2022}, Unique-ID = {WOS:000381005000002}, }
