to discuss the book with. Many people at the Department of Computer Science at the University of Warwick assisted directly and indirectly. My PhD supervisor Saraswati Kalvala and personal advisor Raja Nagarajan showed nerves of steel while watching me write this book and a PhD simultaneously. Ananda Amatya and Ranko Lazic cheered me along the way. The prolific Doron Peled helped me enormously in the initial approach to Springer. Springer's anonymous reviewers gave many clear and insightful comments on the manuscript at several stages. Vishal Thakur additionally reviewed the book with a super-finetoothed comb. Vishal was supported by Manmeet Singh, who smoothed the review process. The broad general engineering knowledge and massive techni- cal writing experience of all reviewers gave me confidence in the book from an early stage.
