In the thesis, we introduce linear regression models such as Simple Linear Regression, Multiple Regression, and Polynomial Regression. We explain basic methods of the model parameters estimation, Ordinary Least Squares (OLS) and Maximum Likelihood Estimation (MLE). The properties of the estimates, and what assumptions need to be made for the model for the estimates to be the Best Linear Unbiased Estimates (BLUE) are given. The basic Bootstrap methods are introduced. The real world problem is simulated in order to see how measurement error affects the quotient of two estimated models.

This thesis presents the results of an experimental investigation of the hydrodynamic characteristics of the Monoform hull in calm water. The forces acting on a 1.7 meter model were measured as the model was held captive and towed in calm water. The model was tested at speeds up to three meters per second. The rudders were held straight during one part of the study and were deflected during another to test both their ability to correct for pitching moment and to create yaw moments. The draft of the model was also varied during this study and included drafts of 1.90, 2.21, and 2.42 hull diameters. All three forces and all three moments were measured. The model was tested in a 31 meter towing basin located at Virginia Polytechnic Institute and State University. The results are presented in Figure form in the thesis body and in numerical form in an appendix. Recommendations for future work and improvements to the instrumentation are presented along with conclusions at the end of the thesis. / M.S.

This thesis documents the fabrication, testing techniques, and response of a plastic scale model of an orthotropic bridge deck. To economically investigate a two-lane steel bridge deck, plastic AcrylicR was used as a modeling material. Welds were simulated with dichloromethane, a capillary action solvent, and PS-30, a polymerizable cement. Deflections were measured with laboratory dial guages while strains were monitored with strain guages mounted on the deck. The response of the deck to AASHO vehicle axle loads was compared with a discrete element computer program used to analyze orthotropic bridge decks continuous over flexible supports. Results indicate good correlation between measured and computed values for deflection and strains.
