Sirma for the great moments shared together during these years. I would also like to thank my friends back home, whom have continued supporting me and encouraging me during these years, and I would like to thank the Gym for keeping me mentally sane when I was doubting myself, and for giving me the mental strength to keep going.I want to thank my family for their unconditional love and support and dedicate this dissertation to them. They have always been an inspiration for me due to their hard work, and I will be always grateful for all the sacrifices they did for me to be able to pursue what I want in life.
