Ph.D. dissertation research in Dept. of Electrical and Computer Engineering, UCSB Title : Video Compression and Packet Loss Concealment Using
Spatial and Temporal Masking
Abstract: Video compression for wireless communications continues to be an area of great research interest. We examine the interaction of intra and interframe coding and spatial and temporal masking effects to select codec parameters and optimize end-to-end performance. We also develop robust methods for concealing packet losses based upon mode classification and perceptual masking. The operational rate distortion function is employed for system optimization, and the theoretical results are evaluated as enhancements to the H.264 advanced video coding standard. Passed my dissertation proposal in December of
2004!

MS dissertation research in Dept. of Electrical and Computer Engineering, Rice University Title : Discrete-Time Linear Periodically Time-Varying Systems:
Analysis, Realization and Model Reduction
Abstract: Discrete-time linear periodically time-varying(LPTV) systems, considered as a bridge between the well-studied linear time-invariant(LTI) model and the nonlinear time-varying problems in real world, have been receiving increasing attention in recent a few decades. In this research project, we try to understand discrete-time LPTV systems both internally and externally and derive basic theories for anaylisis, realization and model reduction of LPTV systems. Firstly we review the system model for LPTV systems, define its transfer function matrix, Markov parameters, stability, reachability and observability. Then we emphasize on the numerically efficient and stable methods to compute LPTV system grammians and to approximate the eigenvalue decay rate. Another main result of this thesis is Krylov-based moment matching algorithm for model reduction of LPTV systems, which is derived afterwards, and is also compared to the other approach: balancing and balanced truncation of LPTV systems. Almost any application of discrete-time LPTV systems, including periodic digital filters and periodic control theories, demands a periodic state-space model from input-output maps. This periodic realization problem is treated at the end of the thesis with demonstration of applicable non-minimal and quasi-minimal realization methods. MS thesis in

It seems that what I have been doing in the past ten years is just getting degrees and doing "research" work. Wait a second.. Life is not all about school and research. It's about growing up, well, I don't mean growing taller, since I stopped doing that a long time ago. It's about always loving my parents, for their unconditional (really) love and support. It's about trying to be as fantastic as my big sister Lucy but never achieving it. It's about getting a perfect boyfriend and tricking him to ask the question. It's about travelling around and having fun. It's about keeping in touch with old friends. It's about hanging out with the cool group and getting drunk occasionally. And it's about trying cockroaches and being every where (thanks to Mike for both pictures, but they are scary).
