This thesis presents an identification scheme for the dynamic model of a ship at sea. We determine the form of the governing differential equations for a ship which is free to pitch and roll, but constrained in all other degrees of freedom, using a perturbation-energy technique. This technique approximates energy expressions and applies Lagrange's equations for quazi-coordinates to develop the equations of motion. When formulating the energies, we take advantage of the ship's symmetry to reduce the number of terms. The equations of motions are approximated such that they contain quadratic and cubic nonlinear terms. Having the form of the governing equations, we set up the parametric identification procedure. Using the method of multiple scales, we exploit resonances and obtain expressions containing subsets of the parameters to be identified. Then we outline a scheme which uses these expressions in conjunction with experimental data to identify the ship parameters. / M.S.

In chip level testing using hardware description language approach, a difficult question to answer is: What is the best micro-operation perturbation for modeling fault at the chip level? In this thesis, an automatic evaluation system is developed to determine the best micro-operation perturbation. The measure used is the gate level stuck-at fault coverage achieved by the tests derived to cover the micro-operation perturbation faults. For small combinational circuits, it is shown that perturbing the elements into the logic dual is a good choice. For large combinational circuits, it is shown that there is very little variation in the gate level coverage achieved by the various microoperation faults. In this case, if coverage is to be improved, the micro-operation perturbation method must be augmented by other techniques. / Master of Science

The study of noncovalent interactions between aromatic rings and various functional groups is a very popular topic in current computational chemistry. The research presented in this thesis takes steps to bridge the gap between theoretical prototypes and real-world systems. The non-additive contributions to the interaction energy in stacked aromatic systems are measured by expanding the prototype benzene dimer into trimeric and tetrameric systems. We show that the three- and four-body interaction terms generally do not contribute significantly to the overall interaction energy, and that the two-body terms are essentially the same as in the isolated dimer. The sulfur-pi interaction is then studied by using the hydrogen sufide-benzene dimer as a prototype system for theoretical predictions. We obtain higly-accurate potential energy curves, as well as an interaction energy extrapolated to the complete basis set limit. Energy decomposition analysis using symmetry-adapted perturbation theory shows that the sulfur-pi interaction is primarily electrostatic in nature. These theoretical results are then compared to an analysis of real sulfur-pi contacts found by searching protein structures in the Brookhaven Protein DataBank. We find that the most frequently seen configuration does not correspond to the theoretically predicted equilibrium for sydrogen sulfide-benzene, but instead to a configuration that suggests an alkyl-pi interaction involving the carbon adjacent to the sulfur atom. We believe our findings indicate that environmental effects within proteins are altering the energetics of the sulfur-pi interaction so that other functional groups are preferred for interacting with the aromatic ring.
