With the explosion in the availability of user-generated videos documenting any conflicts and human rights abuses around the world, analysts and researchers increasingly find themselves overwhelmed with massive amounts of video data to acquire and analyze useful information. In this paper, we develop a temporal localization framework for intense audio events in videos which addresses the problem....
In the era of social media, a large number of user-generated videos are uploaded to the Internet every day, capturing events all over the world. Reconstructing the event truth based on information mined from these videos has been an emerging challenging task. Temporal alignment of videos “in the wild” which capture different moments at different positions with different perspectives is the critical...
Feature selection can improve classification accuracy and decrease the computational complexity of classification. Data features in intrusion detection systems (IDS) always present the problem of imbalanced classification in which some classifications only have a few instances while others have many instances. This imbalance can obviously limit classification efficiency, but few efforts have been...
Studies of cardiovascular system have been the hot point generally concerned as well as extraordinarily significant issue of bioscience. Because of the complexity of cardiovascular system, it is difficult to research the internal principle completely. Consequently, it is usual to study by modeling and simulation. In this article, the cardiovascular system model was established by using Matlab/Simulink...
With the increasing use of audio sensors in user generated content collection, how to detect semantic concepts using audio streams has become an important research problem. In this paper, we present a semantic concept annotation system using soundtracks/ audio of the video. We investigate three different acoustic feature representations for audio semantic concept annotation and explore fusion of audio...
Exonuclease VII (ExoVII) of Escherichia coli is a single strandspecific DNA nuclease composed of two different subunits: the large subunit, XseA, and the small subunit, XseB. In this study, we found that multicopy single-stranded DNAs (msDNAs), Ec83 and Ec78, are the in vivo substrates of ExoVII; the enzyme cuts the phosphodiester bond between the fourth and fifth nucleotides from the 5′end. We used...
In order to assure the quality of software, early detection of defects is highly recommended. Code review is one of effective way for such early detection of defects in software. Code review activities must contain various useful insights for software quality. However, especially in open source software developments, records of code review merely exist. In this study, we try to analyze a code review...
