Open Source Software/Systems in Humanitarian Applications (H-FOSS)
No full textInternational audienceIn the past few years we've seen many catastrophic natural disasters, most recently the Haitian and the Chilean Earthquakes. Others include the 2004 Indian Ocean Earthquake and Tsunami, the 2005 Kashmir earthquake, the 2008 Sichuan earthquake, and Cyclone Nargis that hit Myanmar in 2008. Because these events are rare and often impact poor countries, the development of information systems that support humanitarian and crises response may not be profitable, and thus rarely developed. Systems needed to track medical services to populations of poor nations are often not developed nor deployed because there is no profitable business model for such products. Commercially systems typically require expensive training and hardware not practical in poor underserved places on the plane
Warehousing and Studying Open Source Versioning Metadata
No full textInternational audienceIn this paper, we describe the downloading and warehousing of Open Source Software (OSS) versioning metadata from SourceForge, BerliOS Developer, and GNU Savannah. This data enables and supports research in areas such as software engineering, open source phenomena, social network analysis, data mining, and project management. This newly-formed database containing Concurrent Versions System (CVS) and Subversion (SVN) metadata offers new research opportunities for large-scale OSS development analysis. The CVS and SVN data is juxtaposed with the SourceForge.net Research Data Archive [5] for the purpose of performing more powerful and interesting queries. We also present an initial statistical analysis of some of the most active projects
Preferential Nucleation of Cobalt Nanoclusters on the Faceted Rhenium(1231) Surface
No full textWe have studied the preferential nucleation of cobalt nanoclusters on oxidized faceted rhenium(1231) by means of Auger electron spectroscopy (AES), low energy electron diffraction (LEED), and scanning tunneling microscopy (STM). Preferential nucleation means that the Co nanoclusters form at specific sites on the substrate. In contrast to previous nanostructure studies of preferential nanocluster nucleation in metal on metal experiments, we use a surface that is both oxidized and faceted to form a nanotemplate. It is shown that for cobalt coverage between 1.6 ML and 3 ML, preferential nucleation of cobalt nanoclusters occurs on this faceted surface. It is also shown that by varying the parameters of cobalt coverage, facet width and annealing temperature, the cobalt nanocluster size can be varied. The cobalt nanocluster system may prove to be a model system for future studies of different substrates and overlayers more relevant to catalytic reactions. ii Acknowledgement This work would have been impossible without the support and guidance of Professor Theodore Madey during my studies at Rutgers University. I would like to thank Dr. Madey for giving me the opportunity to work in his group, which was a great experience for me. I would also like to thank Mr. Hao Wang for introducing me to the experimental setup and all its secrets, for his patience and advice. I would like to thank my family for all of their support during my academic career. I would especially like to thank Cassie for letting me accompany her on long walks around the neighborhood. ii
The Present and Future of FLOSS Data Archives
No full textInternational audienceThis is a proposal for a panel presentation to be held during the OSS2010 conference in South Bend, IN. The purpose of this panel will be to discuss the features available in current archives of data about open source projects. The panel will also discuss possible future activities and features to be implemented into these data archives. Community feedback, requests, and questions will also be integrated into this panel discussion
The FOSS 2010 Community Report
No full textInternational audienceThis is a proposal for a panel presentation to be held during the OSS2010 conference in South Bend, IN. The purpose of this panel will be to disseminate the findings from the related FOSS2010 workshop, a CCCsponsored exploratory workshop held in Irvine, California in February. At the OSS conference we wish to give first a report of what was learned at the FOSS workshop, and then to glean important feedback from community members who were unable to be at the FOSS workshop

No full textAbstract. Software is central to the functioning of modern computer-based society. The OSS (Open Source Software) phenomenon is a novel, widely growing approach to develop both applications and infrastructure software. In this research, we studied the community network of the SourceForge.net, especially the structure and evolution of the community network, to understand the Open Source Software movement. We applied three different analyses on the network, including structure analysis, centrality analysis and path analysis. By applying these analyses, we are able to gain insights of the network development and its influence to individual developments
