+I dedicate this dissertation to my beloved wife Dania, my children: Elias,
+Yasser and Mehdi. My family, your unwavering support, encouragement, and
+constant love throughout this Ph.D. study was incredible. My wife and children have
+supported me with prayers, encouraging words that gave me strength to make this dream
+a reality. I am truly thankful to my God for having you in my life. I love you.
+This dissertation has also been dedicated to my parents. From an early age, they
+instilled in me a desire to learn, and made sacrifices so as to I have access to a high-
+quality education. Without their support and guidance, I would not be where I am today.
+Dear Mom and Dad, I can not thank you enough for all the support and love you have
+given me. I know you would have been very proud of me. Thank you so much for your
+love.
+I dedicate this work as well to my brothers, sisters, and their families, whose support
+and encouragement helped me to follow through and not give up.
+I would like to extend my dedication to my friends who supported me.
