4 This dissertation has presented the work and research I have
5 accomplished in the past five years. Chapt.~\ref{chapt:RSA}
6 illustrates one of the first problems I had applied myself to. Given a
7 relatively simple model, could we account for the differences seen in
8 experiment? By using the methods described in Monte Carlo modeling, I
9 was able to write several simulations that provided a clear
10 explanation for the majority of the experimental evidence.
11
12 Later in Chapt.~\ref{chapt:oopse} I present the work I had to do in
13 order to solve more complex research problems. It became clear, after
14 the work on the RSA simulations, that even simple simulations can take
15 a great deal of programming. If I were to simulate the bilayer
16 simulations I wanted to investigate, a sophisticated molecular
17 modeling package was needed. After examining the options available at
18 the time, writing an advanced simulation suite was the best method
19 of accomplishing my goals.
20
21 Working with my colleagues we have developed {\sc oopse} to the point
22 where it is capable of many unique simulation features. It properly
23 integrates rigid body dynamics. It has the capabilities to model
24 dipoles rather than point charges only. It can use the MPI interface
25 to calculate the long range forces across multiple processors. And
26 lastly, it is open source, so that other scientists may use the code,
27 and contribute back to the project to enhance the package.
28
29 Lastly Chapt.~\ref{chapt:lipid} presents the research for which I
30 originally set about the development of {\sc oopse}. The lipid model
31 was under continual development while {\sc oopse} was being
32 designed. In fact many of the integration ensembles in {\sc oopse}
33 were specifically written to continue development of the lipid
34 model. The set of simulations presented in the chapter proved that the
35 model was capable of spontaneously forming bilayers. It also explored
36 the properties of the bilayers formed over a range of
37 temperatures. Further extensions to the model will likely include
38 exploration of dipole strength on the head as well as varying chain
39 configurations (one chain versus two chains, etc.). However, at this
40 point there are many questions that can now be explored with this model
41 such as the inclusion molecules to diffuse through the bilayer, or
42 perhaps exploration of special phases such as the ripple phase.
