I would not have been able to do this without the help of my family, friends and of course, my promotor Prof. Dr. Inge Huybrechts. She was always eager to lend support, especially during though moments, and was available when I had any questions or needed any help. Furthermore, I would like to thank a few special people that aided me throughout this process. Firstly, my parents, without whom I would not have been able to bring it home. Secondly, I would like to thank my girlfriend Kimberley and all- time best friend Thomas, who’s advice and support were deeply appreciated. Lastly, I won’t forget all others who were there when I needed them the most. Thank you. 5 | P a g e 6 | P a g e Contents Abstract ........................................................................................................................................ 1 Abstract ........................................................................................................................................ 3 1.
