Acknowledgements
I would like to thank my committee members: my advisor, Michael Harrison, for his
support, guidance, and patience during my long and somewhat chaotic quest for a PhD,
Susan Graham, for her advice and encouragement, and Mary Kay Duggan, for some very
stimulating discussions on the history of printing and the Reformation.
My research would not have been possible without the help of the rest of the Ensemble
group, including Steve Procter, Vance Maverick, Tom Phelps, Ethan Munson, Roy Goldman,
Brian Dennis, Kannan Muthukkaruppan, Robert Wahbe, Tim Wagner, and Bill Maddox.
Ming Lin, Ioannis Emiris, and John Canny signicantly contributed to the Asgard project,
in the areas of collision detection and convex hull calculation. I also owe thanks to Armin
Wulf, Mike Hohmeyer, and the rest of the ICEM CFD team for providing a great place to
work and some very good ideas while nishing this dissertation.
I would like to thank my aunts Alice, Elene, Mary, and Dorothy, my uncle Fred, and my
cousins Bill, Ron, and Fred, for all they have done for me, and also Tom, Matt, Pat, and
especially Ginger.
Finally, I would like to acknowledge all the people who have been important to me in
numerous ways over the last few years, without whose inuence I would have nished a bit
sooner but had a lot less fun. Including but not limited to, and in no particular order:
Pete French, Tom and Linda O'Toole, Sonny and Stan Friedman, Maureen Master, Carla
Markwart, Birgitta Sylvan, Rosemary Busher, Leah Slyder, Amy Lee, Chris Loverro, and
Ylva Lindholm.
