ACKNOWLEDGEMENTS
I would like to thank Dr. Barbaros Celikkol for introducing me to the world of Ocean
Engineering which enabled me to complete my Ph.D. During the course of my 7 years at
UNH, he had been an excellent mentor and a great friend, always showing his support inside
and outside the university, expecting nothing in return but my success. He was a role model
for me and I feel privileged to learn from him. I will never be able to repay him my gratitude
in my lifetime.
Thanks to Dr. May-Win Thein for creating a research environment which helped me to
become an independent researcher. I appreciate her support and generosity during my entire
study. I also enjoyed our conference trips to Taipei, Keyport, Hampton Roads and Orlando.
I am grateful to Dr. Shachak Pe’eri for guiding me throughout the research and his
contributions on my professional and personal development. It was a great pleasure for me
to work with him and be a part of the same team. I learned a lot from him and I am looking
forward to learning from him even more.
Dr. Yuri Rzhanov was always there when I got stuck on the research. I enjoyed our
discussions on the detector array simulator. He expanded my horizons by looking at things
from a different point of view.
Many thanks to Dr. Robinson Swift for his time in evaluating the dissertation.
I would also like to thank to Dr. Martin Renken for the technical discussions which
improved the quality of the research.
Paul Lavoie contributed greatly on the design and machining of the waterproof acrylic
fixtures He went above and beyond to help me carry out my research and he was very patient
v
with me when I had questions.
Matt Birkebak and Tim Brown worked long late hours with me in Chase Ocean Engi-
neering Lab during the experimental stage of the research. It was also a pleasure for me to
be the grad student adviser of their Harbor Security senior design team.
I also had the pleasure of being the grad student adviser of UNH Remotely Operated
Vehicle (ROV) teams from 2011-2015. I also would like to thank to each member of the
ROV teams for the past 4 years.
Thanks to Tom Fuller and Jesse Mailhot for their contributions on the prototype data
acquisition system for the detector array.
The materials and supplies used in this research were funded by Naval Engineering Ed-
ucation Consortium (NEEC) and Naval Sea Systems Command (NAVSEA). I acknowledge
the funding sources from UNH Graduate School Dissertation Fellowship (2014-2015), the
LINK Foundation Fellowship for Ocean Engineering and Instrumentation (2013-2014), UNH
SummerTeachingAssistantFellowship(2012), LeslieS.HubbardMarineEndowmenttosup-
port Marine Research Development/Equipment (2012). I also acknowledge UNH Mechanical
Engineering Department for supporting me through Teaching Assistant appointments.
Finally, I would like to thank to my family who was always there to support me. They
helped me to get through the turbulence of living abroad.
