    • Adaptive Nonparametric Distribution-free Procedures In Factorial Data Analysis 

      Ferim, Richard Nzagong (Mathematics, 2010-03-03)
      Many statisticians have questioned the basic assumptions about underlying models which might dominate the analysis of the data in many cases. The assumption of normality without much thought is of concern to a growing group ...
    • Advancements And Applications Of Nonstandard Finite Difference Methods 

      Wood, Daniel
      A class of dynamically consistent numerical methods are analyzed for general n-dimensional productive-destructive systems (PDS). Using this analysis, a methodology for constructing positive and elementary stable nonstandard ...

      Heijmans, J. G. C. (University of Texas at ArlingtonDepartment of Mathematics, 1991-08)
      Von Neumann-Morgenstern solutions (stable sets) for cooperative sidepayment games are notoriously difficult to find. This paper provides guidelines on how to find discriminatory vN-M solutions and exhibits some difficulties ...
    • Alternative transmission modes for Trypanosoma cruzi 

      Kribs, Christopher (American Institute of Mathematical SciencesMathematics Department, University of Texas at ArlingtonMathematical and Computational Modeling Sciences Center, Arizona State University, 2010-07)
      The parasite Trypanosoma cruzi, which causes Chagas’ disease, is typically transmitted through a cycle in which vectors become infected through bloodmeals on infected hosts and then infect other hosts through defecation at ...
    • Am I too fat? Bulimia as an epidemic 

      Kribs, Christopher; Gonzalez, Beverly; Huerta-Sanchez, Emilia; Ortiz-Nieves, Angela; Vazquez-Alvarez, Terannie (ElsevierDepartment of Mathematics, University of Texas at Arlington, 2003)
      For at least the past ten years, eating disorders have had a major impact in the physical and mental health of women, particularly young women. Anorexia and bulimia nervosa are closely linked eating disorders. Anorexia ...
    • Analysis And Simulation In Neuron And Fibrosis Models 

      Perez Gonzalez, Humberto D. (Mathematics, 2009-09-16)
      In this work, we use analysis and numerical simulations to study the change of collective behaviorof two synaptically coupled square bursting systems, the effect of noise inan elliptic bursting system and foreign body ...
    • An Analysis of Stress Wave Propagation in Slender Bars Using a Discrete Particle Approach 

      Greenspan, Donald; Reeves, W. R. (University of Texas at ArlingtonDepartment of Mathematics, 1980-12)
      In this paper, a discrete particle approach is developed for the quantitative analysis of stress wave propagation in metal bars. Though linear forces are emphasized, nonlinear forces are also considered. Cylindrical, ...
    • Analytical and Numerical Studies on the States of Ions and Atoms 

      Greenspan, Donald (University of Texas at ArlingtonDepartment of Mathematics, 1985)
      A speculative model is described which refines and extends the method of Bohr to various atoms and ions which have four or fewer electrons. The results for ground, single, and multiple excited states are of unexpectedly ...
    • Applications And Adaptations Of A Globally Convergent Numerical Method In Inverse Problems 

      Rhoden, Aubrey (Mathematics, 2013-07-22)
      In our terminology "globally convergent numerical method" means a numerical method whose convergence to a good approximation of the correct solution is independent of the initial approximation in inverse problems. A numerical ...
    • Applications Of Cubical Arrays In The Study Of Finite Semifields 

      Aman, Kelly Casimir (Mathematics, 2014-09-17)
      It is well known that any finite semifield, S, can be viewed as an n-dimensional vector space over a finite field or prime order, Fp, and that the multiplication in S defines and can be defined by an n x n x n cubical ...
