I would like to dedicate this book to my late father who will always be there in my thoughts for the love and encouragement he gave me to explore new things in life. I would like to thank my family, my mother and my sister, for putting up with me during my long writing and research sessions. I would also like to thank my friends and colleagues who encouraged me and kept the momentum going. I would like to convey deep gratitude to my mentor, Sharoon Thomas, who introduced me to these technologies and helped me learn a lot. Without the support of all of them, I would have never been able to learn these technologies and complete this book.
