WNCG Postdoctoral Associate Juan Sebastian Gomez-Diaz received the Junior Raj Mittra Travel Grant (RMTG) award to attend the 2015 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting, which will take place in Vancouver, Canada this July.
Each year, the UT Department of Electrical and Computer Engineering (ECE) hosts a series of Senior Design Projects, which the undergraduate student teams present at the end of each semester during the Senior Design Open House. The day-long Open House event provides a unique opportunity for students to showcase and demonstrate their work.
While WNCG consists mostly of graduate students, a select few undergraduates also engage in research projects and startups with WNCG faculty and students. Many of them presented during this year's Open House.
WNCG alumni, Prof. Harpreet S. Dhillon and Dr. Radha Krishna Ganti, along with WNCG Profs. Jeffrey Andrews and François Baccelli, recently received the 2015 IEEE Communications Society Young Author Best Paper Award. They received the award for their paper entitled “Modeling and Analysis of K-Tier Downlink Heterogeneous Cellular Networks.”
The first of its kind, the Young Author Best Paper Award covers all publications of the IEEE Communications Society, which includes eight monthly or bi-monthly magazines and 23 multi-annual journal publications.
Last month, Todd Humphreys, an assistant professor in the Department of Aerospace Engineering and Engineering Mechanics and WNCG, testified before the U.S. House Committee on Homeland Security's Subcommittee on Oversight and Management Efficiency. Humphreys was asked to speak at the hearing, "Unmanned Aerial System Threats: Exploring Security Implications and Mitigation Technologies," because of his expertise in unmanned aerial vehicles, UAVs.
In a joint work with Venkat Anantharam from UC Berkeley, WNCG Prof. François Baccelli derived the capacity region in the Poltyrev sense of the dimension matched MAC channel. They gave a representation of the error probabilities for each subset of transmitters based on Palm theory, and random coding exponents for each type of error event in the case without power constraints, in the case of independent and identically distributed Gaussian noise, with arbitrary positive definite covariance matrix at each time.
Prof. Alan Bovik and his student Lark Kwon Choi in the WNCG Laboratory for Image and Video Engineering (LIVE) and Prof. Lawrence Cormack in the Center for Perceptual Systems (CPS) in the Department of Psychology study the influence of motion on the visibility of flicker distortions in naturalistic videos.
Approximate computing is an aggressive design technique aimed at achieving significant energy savings by trading off computational precision and accuracy in inherently error-tolerant applications. This introduces a new notion of quality as a fundamental design parameter. While ad-hoc solutions have been explored at various levels, systematic design approaches are lacking.
Traffic congestion aggravates the daily life of millions of people around the globe and congestion games from game theory provide a suitable tool to understand its effects and offer insights on how to alleviate it. Classic congestion games assume deterministic edge delays, while in reality delays are uncertain and risk-averse drivers might prefer longer but safer routes, further exacerbating the problem of increased travel times and emissions.
A central question in decision-making under uncertainty is how to mitigate risk.
Databases in domains such as healthcare are routinely released to the public in aggregated form to preserve privacy. However, naive application of existing modeling techniques on aggregated data is affected by ecological fallacy that can drastically reduce the accuracy of results and often lead to misleading inferences at the individual level.
