I dedicate this book to . . . My parents, Shivakumara Setty V and Anasuya T M who blessed me with their love and strength, My wife, Chaitra Prabhudeva and my son Shishir who shared their time and support, My in-laws, Prabhudeva T M and Krishnaveni B who provided help and courage, and to all my school teachers to bestow lots of love and knowledge. —Shailesh Kumar Shivakumar To lovers of books . . . I hope this book aids you to get your work out to a wider audience. I would love nothing more than to see the book in the hands of people everywhere—students in the classroom, researchers, browsers in the bookstore, and professionals. That’s a great challenge, but it is certainly worth an attempt. —Sourabhh Sethii
