Background India’s economic growth rate in recent years has been fairly impressive. But, it has been consistently failing to make considerable progress in achieving health related Millennium Development Goal (MDG) targets. Lack of coherence between provisions and utilization becomes the face of the problem. Inadequacies in outreach, access and affordability coupled with escalating healthcare co...

The Data Preservation Alliance for the Social Sciences (Data-PASS) is a partnership of six major U.S. institutions with a strong focus on archiving social science research. The partnership is supported by an award from the Library of Congress through its National Digital Information Infrastructure and Preservation Program (NDIIPP). The goal of DataPASS is to acquire and preserve data at-risk of...

We present a comprehensive evaluation of shot-based visual and audio features for MediaEval 2013 Violent Scenes Detection Affect Task. To obtain visual features, we use global features, local SIFT features and motion features. For audio features, the popular MFCC is employed. Besides that, we also evaluate the performance of mid-level features which is constructed using visual concepts. We comb...

The National Digital Information Infrastructure and Preservation Program will demonstrate a pilot tools platform called Recollection that supports access to distributed NDIIPP collections. The Recollection platform uses semantic technologies to make NDIIPP collections easier to find, access, share, and integrate with other digital information sources.

We present a deterministic distributed 2-approximation algorithm for the Minimum Weight Vertex Cover problem in the CONGESTmodel whose round complexity isO(log n log∆/ log log∆). This improves over the currently best known deterministic 2-approximation implied by [KVY94]. Our solution generalizes the (2 + ǫ)-approximation algorithm of [BCS17], improving the dependency on ǫ from linear to logari...

The development of Internet and of the news Information and Communication Technology tools have boosted the implementation of distance education, virtual university and virtual laboratory all around the world. Nowadays the only constant in education is change and evolution, long life learning is compulsory, and distance education will be a very powerful answer. In relation with that dictates di...
