\chapter*{Colophon}

%Thanks every body !
Completing my PhD degree is the most intellectually challenging %% FUCK OFF ZERNIKE POLYNOMIALS WERE MORE DIFFICULT --- and actually useful unlike set theory
activity of my first 52 years of my life!                       %% SET THEORY IS A LOAD OF BOLLOCKS
%
The best and worst moments of this  journey 
have been shared with many people. 
%
It has been a great privilege to spend several years 
visiting the Mathematics and Engineering departments of 
the University of Brighton, pushing me forward in clarity of self-expression,
precision through mathematics, critical assessment and carefully crafted English,
its members will always remain dear to me.

%
My first debt of gratitude must go to my supervisors, 
Dr. C Garret,          %% TOP BLOKE
Professor J. Howse and %% JAVALA LAT HUND
Dr. A. Fish.           %% JAVALA LAT HUND
%
They patiently provided the guidance, 
encouragement and advice necessary for me to proceed through the 
research, consolidation and write-up phases of the PhD program,
to submit three papers to conferences~\cite{syssafe2011,syssafe2012,Clark_fastzone}  
and to complete and submit this thesis. 

%
I owe a debt of thanks to Dr J. flower, my MSc project supervisor, 
who explained that the chapter in my project documentation postulating a modular form of
FMEA---which had obvious potential for making FMEA
more efficient---was a concept worthy of being developed for a PhD and assisting  me
to submit this as a conference paper~\cite{Clark200519}.
%
Further I thank her for encouraging me to apply for the PhD. %% PITY SHE DID NOT STAY ON AS MY PHD SUPERVISOR
%

I am deeply thankful to the directors of Energy Technology Control not only for
funding this course, but providing training and work experience in the
field of safety critical engineering, and giving me Friday
afternoons to pursue my studies.
%
At Energy Technology Control, the following people gave encouragement, and
validated the concepts for modular FMEA that I was proposing, Martin~Thirsk, Colin~Talmay,
Darren~Legge and Hazel~Anderson. The environment and context of the work there
was very useful for clarifying concepts relating to FMEA and 
safety, at least once a week there would be a new practical case study arising
and being discussed, be it the observability of the effect of failures in an amplifier,
or how a particular sensor could fail. 
%
The field of industrial burner control
is rich with practical examples that my new methodology have been % be
applied to and thus the theoretical aspects were often
sounded out  against `real~world' problems.
%
These real~world failure scenarios were reflected in the 
design documentation, often submitted in support of 
safety accreditation, that I am tasked to produce there.
%
Again I thank energy Technology control Ltd, for giving me
these parallel tasks, which aided my studies.

%
These Engineers, whose whole careers
have been focused on the safety critical electronic/computing area,
gave valuable time to look at and comment on my FMMD proposals.

% Grandma Serife Gur and grandaunt Fadime Altinteril, who left us too soon.

I wish to thank my parents, Jeniffer and Richard Clark.
% MY MUM for proof reading alot!
I hope that this work makes you proud.
