First and for most, I would like to thank the almighty God for the providence and faithful
guidance; without whom nothing would have come to this end. He protected me and for this I
will always honor my God and all praise and glory to him, for granting me the ability and
strength to accomplish this thesis all the way through. In addition, the completion of this
thesis would not have been possible without the assistance, courage and support of a number
of people; therefore, I would like to acknowledge them. And also, I would like to extend my
deepest gratitude and great respect to my thesis principal advisor, Dr. Getasew Yaregal
(Ass.Proffesor), for his tremendous academic support, valuable suggestions, and thorough
constructive guidance in writing this thesis with wisdom and patience; without his genuine
advice this research would not have been possible. I really appreciate his invaluable guidance
and advice from the conception of my thesis to its realization in a statement. Next foremost,
my humble gratitude goes to my Co-Advisor, Getahun Kelemework (Ass.Proffesor), who
tirelessly advised and guided me through the preparation of this work, his technical support

appreciation to my beloved Sister, Ms Senait Demissie, for his continuous financial and
moral support, encouragement, guidance, direction that she has given me and best wishes
