Acknowledgements 
My deepest gratitude goes to Dr. Rafiqul Islam for his unwavering support and 
collegiality throughout this journey. Your patience, motivation, and guidance has helped me 
throughout my research. I could not possibly have had a better advisor and mentor for my 
DIT study. 
My special thanks to my wife, Arzu, and two kids, Jemre and Azra, for all your support 
and endless love. I know I steal a lot of time from you and spend it in my research; that’s 
why, I cannot thank you enough. 
My parents—they never went to school, they never had a chance to read and write. But 
all their life, they worked really hard for me to get an education and no words can explain 
how thankful I am for all that you have done. The same credit goes to my brothers; they 
supported me during my early education, and this simple line of thanks cannot reflect the 
respect I have for both of you
