Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...

We propose a lecture-on-demand system, which searches lecture videos for segments relevant to user information needs. We utilize the benefits of textbooks and audio/video data corresponding to a single lecture. Our system extracts the audio track from a target lecture video, generates a transcription by large vocabulary continuous speech recognition, and produces a textual index. Users can sele...

Past parametric tests of demand system rank employed polynomial Engel curve systems. However, by Gorman’s (1981) theorem, the maximum possible rank of a utility derived polynomial demand system is three. The present paper proposes a class of demand systems that are utility derived, are close to polynomial, and have rank four. These systems nest rational polynomial demands, and so can be used to...

An Additive Double-Logarithmic Consumer Demand System Lester D. Taylor University of Arizona Despite obvious theoretical shortcomings, the double-logarithmic function, because of ease of estimation and generally superior fit, is often the demand function of choice in applied demand analysis. However, the drawback to double-logarithmic demand functions is that they are not theoretically plausibl...

Unusually high correlation in activities among users in social media is an indicator of bot behavior. We have developed a system, called DeBot, that identifies such bots in Twitter network. Our system reports and archives thousands of bot accounts every day. DeBot is an unsupervised method capable of detecting bots in a parameter-free fashion. In February 2017, DeBot has collected over 710K uni...

With recent developments in technologies, video streaming becomes common on the Internet. Copyright protection of video contents is becoming essential. Thus, an RTSP-Based Video-On-Demand System with watermarking is developed in this project. The system is developed in Java. It is successfully developed with capability to stream stored and real-time captured videos. It can also save captured vi...
