This Bachelor thesis has been carried out at Fachbereich Energietechnik Aachen University of Applied Sciences Jülich , Germany This thesis was supervised by : Prof. Dr. Alexander Kern Prof. Dr. Christoph Helsper I certify that this work has been carried out and written up entirely by myself. No literature references and resources other than cited have been used. Jülich , Germany , June 2011
Acknowledgments I would like to express my deepest gratitude to Prof. Dr. Alexander Kern, for his expertise, understanding and guidance, thanks for correcting this thesis over and over again. And I also want to thank Prof. Dr. Christoph Helsper for his suggestions and supervision of my project. Also I would like to thank both of my professors, for their great help in the past several years. At the same time, I would like to thank all Professors of FH Aachen who had given me so much advises and help during my study in Germany. And I would like to thank my family and my friends for their deep love and support. Thanks very much.
