A Gabor system is a collection of modulated and translated copies of a window function. If we have a signal in $L^2(\mathbb{R})$, it can be analyzed with a Gabor system generated by a certain window $g$ and then synthesized ...

Semiconductor lasers have become the most widely utilized form of coherent light emitters. Aluminum gallium arsenide is the prototype material system in heterostructure laser technology. New fabrication techniques that are ...

The ability to walk can be severely compromised by a lower-limb amputation, which can have long-reaching consequences to the individual’s health and safety. It has been reported that the high incidence of lower back pain ...

This thesis contains three investigations examining gait variability in people with multiple sclerosis (MS), which is a neurological disease that can result in significant walking impairment. Gait variability, i.e. ...

The crystal structure of GalD indicates that His 185 may serve as a general acid catalyst to facilitate the departure of the 3-OH leaving group and/or stereospecifically protonate the product in the subsequent tautomerization ...

Finally, new techniques of scientific visualization, which is an integral part of computational science research, are explored in the context of boundary element method. This investigation includes developing new modules ...

AlGaN/GaN high electron mobility transistors (HEMTs) have shown promising high speed performance, both high microwave power and low microwave noise. In this dissertation, the millimeter-wave and microwave power performance ...
