On real and padic Bezoutians
(20110107)We study the quadratic form induced by the Bezoutian of two polynomials p and q, considering four problems. First, over R, in the separable case we count the number of configurations of real roots of p and q for which the ... 

On rings with commuting ideals
(20121129)This report is a summarization and extension of previous work done by Dr. Efraim Armendariz, University of Texas at Austin, and Dr. Henry E. Heatherly, University of Lousiana Lafayette, on the topic of rings with commuting ... 
On semantic reference and discerning referential intentions
(20110105)In Speaker’s Reference and Semantic Reference, Saul Kripke posited two kinds of reference involved in every use of a designator—a semantic reference, to the object picked out by the meaning of the words used—and a speaker ... 
On some distribution problems in Analytic Number Theory
(20100826)This dissertation consists of three parts. In the first part we consider the equidistribution of roots of quadratic congruences. The roots of quadratic congruences are known to be equidistributed. However,we establish a ... 
On some problems in the simulation of flow and transport through porous media
(20091020)The dynamic solution of multiphase flow through porous media is of special interest to several fields of science and engineering, such as petroleum, geology and geophysics, biomedical, civil and environmental, chemical ... 
On some residual and locally virtual properties of groups
(20100921)We define a strong form of subgroup separability, which we call RS separability, and we use this to combine LERF and Agol’s RFRS condition on groups into a property called LVRSS. We show that some infinite classes of groups ... 
On state repression of journalists : a comparison of Egypt's treatment of print journalists and bloggers, 20042008
(20100826)In 2008, the Committee for the Protection of Journalists reports, Internet journalists comprised the worldwide plurality of imprisoned media workers for the first time. Why are Internet journalists subject to higher levels ... 
On study of deterministic conservative solvers for the nonlinear boltzmann and landau transport equations
(20140819)The Boltzmann Transport Equation (BTE) has been the keystone of the kinetic theory, which is at the center of Statistical Mechanics bridging the gap between the atomic structures and the continuumlike behaviors. The ... 
On S₁strictly singular operators
(20101008)Let X be a Banach space and denote by SS₁(X) the set of all S₁strictly singular operators from X to X. We prove that there is a Banach space X such that SS₁(X) is not a closed ideal. More specifically, we construct space ... 
On the arresting efficiency of spiral buckle arrestors for offshore pipelines
(20121105)Buckle arrestors are devices placed along an offshore pipeline for the purpose of arresting an incoming propagating buckle. Typically, buckle arrestors locally increase the pipe’s bending rigidity in the hoop direction. ... 
On the AubryMather theory for partial differential equations and the stability of stochastically forced ordinary differential equations
(20110601)This dissertation is organized into four chapters: an introduction followed by three chapters, each based on one of three separate papers. In Chapter 2 we consider gradient descent equations for energy functionals of the ... 
On the behavior of the porous rotating disk electrode
(20120913)The flow, reactions and current in a porous rotating disk electrode (PRDE) is studied experimentally and theoretically. A PRDE is an electrochemically active porous disk mounted on a classic rotating disk electrode (RDE). ... 
On the blowup of fourdimensional Ricci flow singularities
(20130430)In 2002, Feldman, Ilmanen, and Knopf constructed the first example of a nontrivial (i.e. nonconstant curvature) complete noncompact shrinking soliton, and conjectured that it models a Ricci flow singularity forming on ... 
On the canonical components of character varieties of hyperbolic 2bridge link complements
(20111025)This dissertation concerns the study of canonical components of the SL(2, C) character varieties of hyperbolic 3manifolds. Although character varieties have proven to be a useful tool in studying hyperbolic 3manifolds, ... 
On the capacity of multiterminal systems : the interference and fading broadcast channels
(20121012)A central feature of wireless networks is multiple users sharing a common medium. Cellular systems are among the most common examples of such networks. The main phenomenon resulting from this interuser interaction is ... 

On the compressive response of opencell aluminum foams
(20120927)This study is concerned with the mechanical behavior of opencell aluminum foams. In particular the compressive response of aluminum foams is analyzed through careful experiments and analyses. The microstructure of foams ... 
On the crushing of honeycomb under axial compression
(20110215)This thesis presents a comprehensive study of the compressive response of hexagonal honeycomb panels from the initial elastic regime to a fully crushed state. Expanded aluminum alloy honeycomb panels with a cell size of ... 
On the De Regno of St. Thomas Aquinas
(20130423)Can explicitly Christian principles be invoked and put into practice in political life without thereby rendering that politics fideistic, exclusionary and immoderate? Could such principles in fact strengthen the rule of ...
