Acknowledgments
In the name of God, the Beneficent the Merciful
During this research and throughout my years in university, I have received
insight, support, and encouragement from many people, to whom I am grateful
from the bottom of my heart.
First, and foremost, I would like to extend my sincere gratitude toward my
supervisor, Dr. Daniel Lai, for his continuous encouragement, academic guidance,
andpatientsupportthroughthisentirejourney.Iwouldliketothankhimforbeing
the source of inspiration and sharing his expert knowledge at every stage of this
doctoral study. I am also sincerely grateful to my associate supervisor,
Prof. Michael Faulkner, for his practical advices, insightful comments, and critical
views through the course of my research. I greatly appreciate his guidance and
counseling.
My appreciation also goes to TEPS research students and staff members for
creating friendly, supportive, and stimulating atmosphere. I would like to thank
Dr. Francois Rivet, Behailu, Zibo, Clement, and Lance for being supportive col-
leges andcoworkers throughout thePh.D. study. Iamalso greatlythankful for the
administrative staff of College of Engineering and Science and the Graduate
Research Center for their support and assistance in a timely and reliable manner.
Last, but definitely not least, my deepest gratitude goes to my wife for her
endless love and encouragement and to both our loving families for their tireless
support and persistence throughout the whole Ph.D. journey.
