Although much has been written describing the
various reactions to the origin of Species in America, the Mormon reaction to Darwinism has been largely ignored. This dissertation will recount the history of this reaction as exemplified by the life and works of B. H. Roberts. Roberts's intellectual pursuits early in...
Tensor field topology is of importance to research areas of medicine, science, and engineering. Degenerate curves are one of the crucial topological features that provide valuable insights for tensor field visualization. In this thesis, we study the atomic bifurcations of degenerate curves in 3D linear second-order symmetric tensor fields, and...
N-ary relationships, which relate N entities where N is not necessarily two, are omnipresent in real life. In this thesis, we develop a visualization technique for N-ary relationships.
First, we propose a visual metaphor that utilizes vertices and polygons to represent entities and N-ary relationships. Based on this visual metaphor,...
Fluid simulation is an interesting research problem with a wide range of applications including mechanical engineering, special effects in movies and games, and scientific simulation. Due to the complex nature of typical fluid flow equations, there are circumstances where a full volumetric fluid simulation may not be necessary to generate...
A steady-state computer simulation was developed for the
Chemico Urea Process which is owned and operated by Reichhold
Chemicals, Inc., St. Helens, Oregon. The DISCOSSA executive system
was used to process information input and output and to automatically
converge the complex recycle calculations in this process.
The models developed in...
A generalized modeling system was developed for digital computer
simulation of the pharmacodynamic response of selected chemicals
introduced into mammalian systems. The modeling system is based on
the compartmental approach used extensively in pharmacodynamic studies
in which the mammal is assumed to be subdivided into compartments
which interact by means...
The gradient of a velocity vector field is an asymmetric tensor field which can provide critical insight that is difficult to infer from traditional trajectory-based vector field visualization techniques. I describe the structures in the eigenvalue and eigenvector fields of the gradient tensor and how these structures can be used...
