If you can't find me, I'm probably up in ECE 446, off finding good espresso, forgetting to post to my weblog, looking for good graduate students, or coming up with captions for my headshot.

| Speaker | Topic |
|---|---|
| Prof. Ricardo Sanfelice Asst. Professor, AME | "Robust Stability Analysis of Hybrid Control Systems" Driven by recent technological advances, hybrid systems have become prevalent when describing complex systems with both continuous and discrete dynamics. This ongoing trend has been the thrust for research on modeling, stability analysis, control design, validation, verification, and simulation of hybrid systems. These research efforts are also relevant in the design of advanced control algorithms with mixed continuous/discrete dynamics, that is, hybrid control systems. Even though hybrid control systems have been shown to enhance the robustness properties of the closed-loop system in most applications, the analysis and design for robustness of these systems have not been pursued in a systematic manner due to the lack of formal tools for that purpose. Instead, this has been carried out with tools suitable for the particular application of study. In this short talk, we take a dynamical systems approach to modeling and robust stability analysis of general hybrid systems. We introduce a mathematical framework for robust stability of compact sets and pinpoint several engineering control problems. |
| Shiva Planjery SPACL (Prof. Vasic) | "Iterative decoding beyond belief propagation" At the heart of modern coding theory lies the fact that low-density parity-check (LDPC) codes can be efficiently decoded by belief propagation (BP). The BP is an inference algorithm which operates on a graphical model of a code, and lends itself to low-complexity and high-speed implementations, making it the algorithm of choice in many applications. LDPC codes approach theoretical limits of channel capacity underr BP decoding. However, this capacity approaching property holds only in the asymptotic limit of code length, while codes of practical lengths suffer abrupt performance degradation in the low noise regime known as the error floor phenomenon. Our study of error floor has led to an interesting and surprising finding that it is possible to design iterative decoders which are much simpler yet better than belief propagation! These decoders do not propagate beliefs but a rather different kind of messages that reflect the local structure of the code graph. This talk will briefly introduce this new paradigm. |
| Tao Shu Krunz Lab | "Efficient and truthful mechanisms for opportunistic spectrum access: an economic perspective" Opportunistic spectrum access (OSA) is a new technology that can significantly improve the utilization of the spectrum. Under OSA, a secondary radio (SR) is allowed access to a channel that is not currently being used by the primary radios (PRs) of the channel. In this talk, I will give an economic view on the operation of an OSA network, in which the activities of PRs and SRs are driven by profit. I will identify various research issues that stem from the for-profit nature of the network. I will also briefly introduce our research achievements on addressing some of these issues. |
