To all my respected teachers; my loving wife Ambika, my sole daughters, Pravitha and Prarthana; my caring brothers, Balu and Gopinath; my dearest friend, Adarsh; the precious gift of my life, my Mom, Indira and my Dad, Jayaram; and my entire family. Thank you for all the support and for everything you have done so far. It is difficult to express my gratitude in words.
