Abstract:
I am thankful to my Creator Allah Subhana-Watala to have guided me throughout this
work at every step and for every new thought which You set up in my mind to improve it. Indeed, I could have done nothing without Your priceless help and guidance. Whosoever helped me throughout the course of my thesis, whether my parents or any
other individual was Your will, so indeed none be worthy of praise but You. I am utterly
thankful to my parents for their support, I am nothing but a piece of everything you have
wanted me to be. I would like to thank mu husband and my best friend, Omair Munir for his sheer support
and love that helped me achieve my dream. I would also like to express my utmost gratitude to my supervisor DR. ASAD WAQAR
MALIK for his help throughout my thesis and his guidance, tremendous support, and
cooperation. I can safely say that I wouldn't have been able to complete my thesis without
his in-depth knowledge of this field. Each time I stumbled because of my personal and
professional issues; he was there with a helping hand that got me where I am right now in
my professional education. There are not enough words to appreciate his patience and
guidance throughout my entire thesis. I am heartily thankful to him. His encouragement, guidance, and support from the initial to the final level enabled me to develop an
understanding of the subject.
