Infinitely Many Perfect and Unitary Perfect Polynomials Over Some GF(q)
(University of Texas at ArlingtonDepartment of Mathematics, 1977-05)**Please note that the full text is embargoed** ABSTRACT: The existence is shown of infinitely many non-splitting perfect polynomials over GF(2d), GF(3d), GF(5d) for each odd integer d > 1, and over GF(2d) for each (even) ... -
The Influence Of Dynamic Visualization On Undergraduate Calculus Learning
The urgent need in the United States to produce an additional one million graduates in the areas of science, technology, engineering and mathematics and previous research into why students choose to abandon their quest to ... -
Influence of environmental factors on college alcohol drinking patterns
(American Institute of Mathematical SciencesDepartment of Mathematics, University of Texas at Arlington, 2013)Alcohol abuse is a major problem, especially among students on and around college campuses. We use the mathematical framework of [16] and study the role of environmental factors on the long term dynamics of an alcohol ... -
Influence of vectors' risk-spreading strategies and environmental stochasticity on the epidemiology and evolution of vector-borne diseaes: the example of Chagas' disease
(Public Library of ScienceDepartment of Mathematics, University of Texas at Arlington, 2013)Insects are known to display strategies that spread the risk of encountering unfavorable conditions, thereby decreasing the extinction probability of genetic lineages in unpredictable environments. To what extent these ... -
An Information Theoretic Approach to Incorporating Prior Information in Binomial Sampling

Interval Estimation of Reliability Characteristics of a k-identical Unit Standby Redundant System
(University of Texas at ArlingtonDepartment of Mathematics, 1977-02)**Please note that the full text is embargoed** ABSTRACT: Standby redundancy is a method for increasing the reliability of a system through the use of additional "backup" units. Assuming perfect failure-sensing and ... -
Interval Estimation of the Noncentrality Parameter of A Gamma Distribution
(University of Texas at ArlingtonDepartment of Mathematics, 1984-09)**Please note that the full text is embargoed** ABSTRACT: Asymptotic confidence interval for the noncentrality parameter of a Gamma distribution (or Chi-squared distribution) is derived. An algorithm for computing the ... -
INVERSE PROBLEMS AND FORWARD PROPAGATION OF OPTICAL FLOW
(2020-08-24)Optical flow is a concept originally introduced in computer vision that quantifies, and aids in the presentation of, motion (flow field) between two or more images. In essence, it is a solution of an inverse problem ... -
An Investigation Of The Conceptual Understanding Of Continuity And Derivatives In Calculus Of Emerging Scholars Versus Non-emerging Scholars Program Students
(Mathematics, 2011-07-14)The Emerging Scholars Program (ESP) has been adapted at colleges and universities across the nation in efforts to increase student access to Science, Technology, Engineering and Mathematics (STEM) disciplines. This study ... -
The Laplace Transform of the Linear Car-following Model
(University of Texas at ArlingtonDepartment of Mathematics, 2008)**Please note that the full text is embargoed** ABSTRACT: Laplace transform is used to analyze the differential-difference equation for the linear car-following model. The car-following model has been developed to describe ... -
Large Deviation Principle For Functional Limit Theorems
(Mathematics, 2009-09-16)We study a family of stochastic additive functionals of Markov processes with locally independent increments switched by jump Markov processes in an asymptotic split phase space. Based on an averaging limit theorem, we ... -
