Acknowledgments
I would like to acknowledge the help I have received from colleagues, students, and friends in the process of writing this book. I especially thank Jonathan Jalbert, Shervin Khazaeli, Saeid Amiri, Sbastien Le Digabel, Marco Broccardo, Luong-Ha Nguyen, Rocio Lilen Segura, and Gerd Brandstetter for helping me with reviewing the manuscript. I also acknowledge the feedback I have received from many students who attended my CIV6540 graduate class at Polytechnique Montreal. I want to thank Michel Goulet, who contributed to the book with several of his photos; as well as Daphne and Daniel Dethier, who provided helpful insights during the design of the book cover. I thank the anonymous reviewers who took the time to read the manuscript and whose comments were integrated into the final version.
In a broader perspective, I would like to thank my family for their inexhaustible support over the years. Also, I want to recognize the constructive influence from my advisers, who guided me since the beginning of my university years: Andr Picard, Mario Fafard, Ian F.C. Smith, and last but certainly not least, Armen Der Kiureghian, who was an inspiration through his lectures and mentoring.
Finally, I want to acknowledge the exceptional freedom I was allowed to have as a young professor by my host institution, Polytechnique Montreal. Without it, I do not see how this book would have been possible.
