Abstract:
A PhD degree document may contain a single name, the name of recipient, but PhD
research itself is a team work. My own work is no exception- I could not have been
able to travel so far on the complex routes of research without the support of many
others who deserve my thanks.
To my advisor, my inspiration, Dr. Sumanta Guha, I wish, some day I could hold
a tin of coke in my hand like him during research, but no, he is the only one in the
world who can do such out of norm things, yet look so stylish. He helped me to polish
my data mining skills, ¯rst in the course work and then during the research. The best
things I enjoyed during the past years of research under his guidance, is the freedom
to make my own path and make myself a self-driven.
To the members of my dissertation committee, namely Prof Dr. Kazi M Ahmed,
and Prof Dr. Mattew N Dailey. Their timely and constructive criticism and suggestions
have a huge role in this study. At times, I had to reshape everything in the light of
their comments.
To my father, who has always been a role model for me. His honesty and sincerity
towards work has been benchmark for me. My journey to where I am today, would
have not taken even a single step without his support and encouragement that was
always there whenever needed.
To my mother, her habit of putting 100% in the job in hand has led me to learn how
to work tirelessly. She actually helped me to learn that God has given an unmatched
ability to human to climb on any height with just a cool head and sincere e®ort.
Finally, to my wife, her love helped me to discover myself. She let me know what
I am, and what I can do. Her belief in me has a great part in ¯nding dare to dreambig and bringing them to reality.
