I would like to express my deep gratitude to my supervisor, A/P Aslaksen, for his patient
guidance, enthusiastic encouragement and useful suggestions for this final year project. I
am so grateful for his willingness to give time so generously. Despite his busy schedule, he
still meets me every week to guide and support me throughout the year. I have benefited
and learnt greatly from this project.
I would also like to thank my lovely family, my understanding boyfriend Jesse, and my
supportive friends Huimin and Jingxian for their continued encouragement and help. Last
but not least, a special thank goes to the spirits in Heaven, who give and support my life on
this beautiful Earth. I have had a really special and meaningful year because of you all.
