    ACKNOWLEDGEMENT I have the pleasure and honor to thank the Almighty God for the gift of wonderful life he has

    given me without which nothing would be done by me.

    In addition, I would like to acknowledge the marvelous contribution made by the Italian Co-

    operation towards this research by availing me with the simulation software that was a

    prerequisite for the successful completion of this research.

    Special thanks go to my supervisor Dr. Kariko B. Buhwezi for the advice and direction offered to

    me during this research

    I would also like to extend my many thanks to Mr. Paul Isaac Musasizi for the academic and

    professional guidance offered to me during the entire research period from the word go.

    Many thanks go to Mr. James Herzing the Product Support Engineer Autodesk Algor for all the

    technical support he extended to me without which it would be difficult to realize the objectives

    of this research.

    Last but not least, I would like to especially thank my family members robina, agness, peter,

    Charles and my dad for all the support psychological and financial that was rendered to enable

    me finish this research, God bless you all.
