Show ACKNOWLEDGEMENTS I thank my advisor Dr. Kris Sikorski and my committee members Dr. Gerard T. Schuster and Dr. Frank Stenger for their continuous assistance and support. I am deeply indebted to Dr. Sikorski for years of guidance and support and countless and invaluable ideas and suggestions. He is the main reason I have enrolled in this program. He has proposed and outlined many of the ideas explored in this work and suggested alternatives when I ran short of ideas. Dr. Schuster, who was my advisor for my first master's degree, has been a teacher, a supporter, and a friend for a decade now and has played a big role in directing me toward getting this degree. He has also patiently explained to me many of the intricate details involved in solving the elastic wave equation. To all of them and many others I offer my deepest gratitude. |
