I would like to express my deepest gratitude to my supervisor David Engblom whose help, guidance and encouragement were always motivating to me. I am also indebted to Anna Eskilsson, Anna Nilsson, Daniel Björk, Milen Kirlov and Nina Ottosson for their friendly and useful supports. Last but not least, I would like to thank my wife and my family for the encouraging environment they have made for me during my education.
