Structural Inference on Reliability in a Lognormal Model
(University of Texas at ArlingtonDepartment of Mathematics, 1975-12)**Please note that the full text is embargoed** ABSTRACT: The theory of structural inference, as developed by Fraser (1968), is based on a group-theoretic approach using invariant Haar measures to Fisher's fiducial theory. ... -
Studies in Rapid Kinetic Reactions by Quasi-Quantum Mechanical, Conservative Methodology
(University of Texas at ArlingtonDepartment of Mathematics, 1990-12)**Please note that the full text is embargoed** ABSTRACT: Simulations are made of prototype, ground state, rapid kinetic reactions for A+BC, in which B, and C are hydrogen atoms and BC is a hydrogen molecule. We study ... -
Study Of Multiple Impacts Of A Rigid Body With A Flat Surface
(Mathematics, 2008-08-08)Both analytical and numerical results are presented for two rigid body problems: a rod colliding with the ground, and a rigid thin plate colliding with the ground. The study of the succession of impacts of the rod with the ... -
A Study of Robustness of Preliminary Tests in Conditionally Specified Regression Models
(University of Texas at ArlingtonDepartment of Mathematics, 1983-05)**Please note that the full text is embargoed** ABSTRACT: The selection of variables in regression analysis is usually done by using preliminary tests. When it is doubtful whether the regression coefficients of a set of ... -
A Study On The B Family Of Shallow Water Wave Equations
(Mathematics, 2009-09-16)In this dissertation we study b family of shallow water wave equations which include classical Korteweg-de Vries, Camassa-Holm and Degasperis-Procesi equations. We first establish the models of the Camassa-Holm and ... -
A Study On The Two Component Periodic Shallow Water Systems
(Mathematics, 2012-07-25)In this dissertation we study the generalized periodic two-component Camassa-Holm system and the generalized periodic two-component Dullin-Gottwald-Holm system, which can be derived from the Euler equation with nonzero ... -

(University of Texas at ArlingtonDepartment of Mathematics, 1989-01)**Please note that the full text is embargoed** ABSTRACT: Microdrop collisions are important in fast kinetic, microwave, nucleation, and rainstorm studies. In this Paper a molecular model of colliding microdrops of water ... -
Supercomputer Simulation of Cracks and Fractures by Quasimolecular Dynamics
(University of Texas at ArlingtonDepartment of Mathematics, 1989)**Please note that the full text is embargoed** ABSTRACT: The gross physical behavior of solids and liquids is the result of atomic or molecular reactions to external forces. Using molecular dynamics, we can study such ... -
Supercomputer Simulation of Liquid Drop Formation on a Solid Surface
(University of Texas at ArlingtonDepartment of Mathematics, 1990-02)**Please note that the full text is embargoed** ABSTRACT: Using a molecular dynamics type approach, we show how to simulate the formation of a liquid drop on a solid surface. Application is made to the case in which the ... -
Supercomputer Simulation of Sessile and Pendent Drops
(University of Texas at ArlingtonDepartment of Mathematics, 1987)**Please note that the full text is embargoed** ABSTRACT: A intermolecular approach is developed for the modeling of sessile and pendent drops. Fundamental mechanisms of drop formation are formulated in terms of gravity ... -
