Prediction of Energy Consumption Behavior

DEDICATION To my loving family iii ACKNOWLEDGEMENTS First of all, I would like to thank my advisor, Professor Nenad Medvidovic, for his kind support and guidance during my Ph.D. course. Whenever I was encountered by some difficult problems in my research, he always encouraged me and kindly helped me solve those problems. He was also the only person who gave me a research opportunity, when I had to find my Ph.D. advisor again at USC four years ago. I also would like to thank Professors Alexander Egyed for serving as the committee members and giving me very useful comments on my research. I was very fortunate to work with many smart friends and colleagues during the last four years. Sam Malek helped me a lot in formalizing and developing the energy consumption estimation framework for distributed Java-based systems. I would like to thank George Edwards for his significant contributions in developing the style-induced energy cost estimation framework. I also wish to thank many other good friends in the Software Architecture Group at USC: I would like to dedicate this dissertation to my loving family. I owed many thanks to my older sister, Hyojung Seo, and older brothers, Chihwan Seo and Chiho Seo, for their support and love. Finally, I would like to express my deep respect to my parents, iv Seongkyu Seo and Jungja Chang. Without all the sacrifices you have made for me, I could not have succeed in this long journey.
