The End. |

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. |

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. |

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. |
