\clearpage \phantomsection \addcontentsline{toc}{chapter}{Acknowledgements} \chapter*{Acknowledgements} I would like to thank Simon Van Mierlo for his excellent guidance, review and feedback of this thesis. I would also like to thank my promotor, Hans Vangheluwe for giving me the chance to re-enroll at university after dropping out a couple of years ago. And naturally, I thank family and friends for their support.
