The Natural Middle of a Complete Resolution
(2021-08-23)It is widely known that minimal free resolutions of a module over a complete intersection ring have nice patterns that arise in their Betti sequences. In the late 1990's Avramov, Gasharov and Peeva defined a new class of ... -
THREE DIMENSIONAL IMAGE RECONSTRUCTION (3DIRECT) OF SPARSE SIGNALS WITH MRI APPLICATION
(2016-11-29)Sparse signal reconstruction has been steadily gaining tremendous attention, specifically in applications of compressed sensing as well as feature selection in signal processing methods [IEEE Signal Processing, Vol. 25 ... -

A Topological Method for Vector-Valued and Nth Order Nonlinear Boundary Value Problems
(University of Texas at ArlingtonDepartment of Mathematics, 1982-05)**Please note that the full text is embargoed** ABSTRACT: The use of topological methods in the analysts of second order nonlinear boundary value problems (BVP for short) in Rn of the form (E) [see pdf for notation] (C) [see ... -
Transmission dynamics and underreporting of Kala-azar in the Indian State of Bihar
(Department of Mathematics, University of Texas at Arlington, 2010)"Kala-azar" (or Indian Visceral Leishmaniasis) is a vector-borne infectious dis- ease affecting communities in tropical and subtropical areas of the world. Bihar, a state in India, has one of the highest prevalence and ... -
Truncated Circular Normal Distribution with Applications in Ballistics and Meteorology
(University of Texas at ArlingtonDepartment of Mathematics, 1973-12)**Please note that the full text is embargoed** ABSTRACT: The use of the circular normal distribution (CND) to describe the behavior of random phenomena of a geophysical nature has been discussed by Crutcher [7, p. 9]. ... -
Twisting Systems and some Quantum P³s with Point Scheme a Rank-2 Quadric
(2022-05-18)In 1996, J. J. Zhang introduced the concept of twisting a graded algebra by a twisting system, which generalizes the concept of twisting a graded algebra by an automorphism (the latter concept having been introduced in an ... -
Two Remarks on Totally Balanced Games
(University of Texas at ArlingtonDepartment of Mathematics, 1996)**Please note that the full text is embargoed** ABSTRACT: Two results on totally balanced TU games are presented. It is first shown that the core of any subgame of a non-negative totally balanced game can be easily obtained ... -
Uniform Weighted Compact / Non-compact Schemes For Shock / Boundary Layer Interaction
(Mathematics, 2008-08-08)The critical problem of CFD is perhaps an accurate approximation of derivatives for a given discrete data set. Based on our previous work on the weighted compact scheme (WCS), a uniform weighted compact / non-compact scheme ... -
The Uniqueness Of Minimal Acyclic Complexes
(Mathematics, 2009-09-16)In this paper, we discuss conditions for uniqueness among minimal acyclic complexes of finitely generated free modules over a commutative local ring which share a common syzygy module. Although such uniqueness occurs over ... -
Unitary Perfect Polynomials Over GF(q)
(University of Texas at ArlingtonDepartment of Mathematics, 1975-03)**Please note that the full text is embargoed** ABSTRACT: For monic polynomials A(x), B(x) e GF[q,x], call B(x) a unitary divisor of A(x) provided (B(x),A(x)/B(x)) = 1 . The polynomial A(x) is called unitary perfect over ... -
USE OF GENERALIZED GAMMA DISTRIBUTION IN MODELING
(2017-06-01)In this study, we have considered analysis of lifetime or survival data with right censoring, which is the most common form of censoring encountered in practice. Assuming a fully parametric setup, the main objective is to ... -
Vaccination strategies and backward bifurcation in age-since-infection structured model
(ElsevierDepartment of Mathematics, University of Texas at Arlington, 2002)We consider models for a disease with acute and chronic infective stages, and variable infectivity and recovery rates, within the context of a vaccination campaign. Models for SIRS and SIS disease cycles exhibit backward ... -
A Value for Digraph-restricted Games
(University of Texas at ArlingtonDepartment of Mathematics, 1997)**Please note that the full text is embargoed** ABSTRACT: Digraph-restricted games model situations where some of the players, due to the lack of communication among them, are unable to cooperate. A digraph-restricted game ... -

Vector consumption and contact process saturation in sylvatic transmission of T. cruzi
(Taylor & FrancisDepartment of Mathematics, University of Texas at Arlington; Universidad de Colima, Mexico, 2006)Recent research in the transmission of the protozoan parasite Trypanosoma cruzi, some strains of which cause Chagas’ disease, suggests that consumption of vectors by sylvatic hosts such as raccoons may play a role in ... -
