First and foremost, I thank Allah Almighty for His mercy, guidance, and kindness in every step of my life. Without His will, nothing would have been possible.
I would like to thank King Fahd University of Petroleum and Minerals for providing me with the opportunity to study and conduct my research in such a supportive environment. My appreciation goes to all my professors and to my department.
My deepest gratitude goes to my supervisor, Dr. Md. Mahfuzur Rahman, for his valuable guidance, patience, and continuous support. His calmness and reassurance helped me overcome challenges and stay motivated throughout this journey. I also extend my thanks to the thesis committee members for their time, comments, and contributions to this work.
My heartfelt thanks to my parents for their unconditional love, prayers, and support. May Allah reward you abundantly, my dear father and mother, for planting in me endless love and faith. I am also grateful to my brothers and sisters, my family, and all my friends who stood by me and shared this journey with love and kindness.
I would like to thank my fiancé, Dr. Mahmoud Ramadneh, for his love, understanding, and continuous support. You have been my source of comfort and strength.
