CKNOWLEDGEMENTS
 
I would like to express my sincere gratitude to my supervisor Dr. Dragos Ilie for the 
continuous support and related research, for his patience, motivation and immense 
knowledge. His supervision helped me during my thesis research and composing of the 
thesis document immensely. I could not imagine a better supervisor and mentor for my 
Master Thesis. 
I would also like to thank my thesis committee: Prof. Kurt Tutschku and Asst.Prof. Patrik 
Arlos including others, for their insightful comments and encouragement. But also the hard 
question without which proper perspective into my thesis wouldn’t be possible.
I thank my fellow classmates for stimulating discussions, constant help and support during 
deadlines and all the fun and memories made over the past five years.
Last but not the least, I would like to thank God, my parents and sister for their constant 
support and backing up at every stage in my life and constant motivation without whom I 
wouldn’t be where I’m today.
