Theory and applications of the shift-invariant, time-varying and undecimated wavelet transforms
In this thesis, we generalize the classical discrete wavelet transform, and construct wavelet transforms that are shift-invariant, time-varying, undecimated, and signal dependent. The result is a set of powerful and efficient ...
System identification for robust control
In the design of a robust control system, one needs a nominal model together with a quantitative bound on the uncertainty that results from under-modeling and disturbances. In this thesis we do not intentionally seek a ...
Performance analysis of parallel I/O models for external mergesort
Since the I/O subsystem is the bottleneck in external mergesort, I/O parallelism can result in substantial performance improvements. Concurrency can be introduced by overlapping I/O requests at different disks, and the ...
Logic design for reliability
Reliability of logic circuits is emerging as an important concern that may limit the benefits of continued scaling of process technology and the emergence of future technology alternatives. Scaling of CMOS devices below ...
