First, we would like to thank our industrial advisors Yiğit Öğretmengil, Başak Baş, Aysen Arıkan and Kerim Kasap not only for providing us the necessary data and spending time for our project, but also for their friendship and support.

We are also grateful to our academic committee which includes our academic advisors Ülkü Gürler and Emre Berk, our course coordinator Bahar Yetiş Kara because they do not only give useful advice, but also accompany us at all meetings throughout the year, in spite of their busy schedule.

Lastly, but not least, we thank USIM Coordinator Yeşim Erdoğan for all the warm help and opportunities she provides throughout the year.
