I would like to thank my advisor Dr. ...... for his continuing guidance, support, and understanding throughout my graduate years. I thank all the past and present members of the ...group for their helpful discussion and sincere encouragement. Special thanks go to.............
No words are adequate to express my thanks to my mother and brother. The warmth and the tenderness of the family they have provided all these years gave me courage to face all the obstacles in my life. I feel paticularly grateful to the unconditional trust and love from my dear husband. Without his constant encouragement and support, this thesis would not exist today.
Finally, I would like to dedicate this thesis to my father, who passed away during the first year of my graduate study, but is always with me in all the sadness and joy in my life.
