Dirk S¨offkerUniv.-Prof. Dr.-Ing. Jo¨rg RaischTag der m¨undlichen Pru¨fung: 10. Oktober 2011Dedicated to my parentsYuqing Qin and Xike Zhangwho teach me to love the world.IVAcknowledgementFirst and foremost, I would like to thank my doctor supervisor Univ.-Prof. Dr.-Ing. Dirk S¨offker, for his precious support on this fascinating topic of doctor thesis,for his providing an open and free academic environment for research, and mostimportantly, but also his invaluable guidance on the development of my world viewand personality. Without him, neither would this work have been initiated andfinished, nor would I have develop a more objective and individual insight than fouryears ago.I am also grateful to Univ.-Prof. Dr.-Ing. Jo¨rg Raisch for his effort being the secondsupervisor for my thesis. Without his keen scientific questions and helpful advicetowards the thesis, there would have been still much more aspects to be improvedin the technical content of this thesis.I thank Univ.-Prof. Dr. rer. nat.
