To properly acknowledge the individuals who positively impacted my life at WPI, I will resort to using two quotes by David Joseph Schwartz and John Quincy Adams:. .. David Joseph Schwartz: "Here is the basic rule for winning success. Let's mark it in the mind and remember it. The rule is: Success depends on the support of other people. The only hurdle between you and what you want to be is the support of other people." I would like to extend my utmost gratitude to Vice Provost of Research, Prof. Bogdan M. Vernescu who was instrumental in opening a new beginning for my Ph.D. endeavor at WPI. In few occasions that I have had the pleasure of meeting with Prof. Varnescu, he inspired me by his respectful mannerism, his willingness to support, and his sound advice. And more close to home, ECE department, Department Head, Prof. Yehia Massoud resolved my administration issue very quickly and efficiently. I greatly appreciate his whole humble demeanor despite his high scholarly achievements. We have a proverb in IRAN that states: "The more fruitful the tree, the more bent it is" and, on the contrary, a fruitless tree with its light weight stands upright!. .. John Quincy Adams: "If your actions inspire others to dream more, learn more, do more and become more, you are a leader." My advisor, Prof. Kaveh Pahlavan can easily be described by the above quote. With his accomplishment and tenure track for many years, he does not swing his weight against the student and on the contrary, there is no iota of ill-intention towards any student. Under Prof. Pahlavan's leadership, I have greatly benefitted from his selflessness, keenness and visionary ideas. We have shared many laughs and has made this endeavor highly educational and fun. Dedicated to two dearest ladies of my life, my Mother, & my Wife. .. Omar Khayyám, Rubaiyat: "To wisely live your life, you don't need to know much Just remember two main rules for the beginning: You better starve, than eat whatever And better be alone, than with whoever.". . .
