Abstract

Firstly, I would like to thank God for everything in life. I would like to thank my parents, Roberto Raddo and Abgail Raddo as well as my girlfriend Anne-Sophie for their constant support, love, encouragement, and total understanding during my long doctoral journey. I would like to thank Ben-Hur V. Borges, Heidi Ottevaere, Idelfonso T. Monroy, and Martin Virte for their contributions to my doctoral research as my academic advisors. I am grateful for their continuous guidance during this long and challenging path, for their helpfulness, confidence, and advice. Special thanks go to Hugo Thienpont and Heidi Ottevaere for the unique offered opportunity to develop part of the doctoral research in Brussels at B-PHOT. I would like to express my gratitude to my great friends: Israel Lot (thanks also for the book's cover), Larissa Lima (thanks also for helping me out so many times),
