    • Uniform Weighted Compact / Non-compact Schemes For Shock / Boundary Layer Interaction 

      Xie, Peng (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 

      Hughes, Meri Trema (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) 

      Beard, Jacob T. B., Jr. (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 

      Yu, Hongbo (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 

      Kribs, Christopher; Martcheva, Maia (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 

      Voshtina, Oltion (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 ...
    • Variation of Constants, Vector Lyapunov Functions and Comparison Theorem 

      Aftabizadeh, A. R. (University of Texas at ArlingtonDepartment of Mathematics, 1980-04)
      **Please note that the full text is embargoed** ABSTRACT: In this paper we combine the above ideas to obtain a new comparison result and discuss its relation to known results. A simple application to stability theory is ...
    • Vector consumption and contact process saturation in sylvatic transmission of T. cruzi 

      Kribs, Christopher (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 ...
    • Vector Lyapunov Functions and Perturbations of Nonlinear Systems 

      Moore, Marion E.; Mitchell, Roger W. (University of Texas at ArlingtonDepartment of Mathematics, 1975-03)
      **Please note that the full text is embargoed** ABSTRACT: Two recent papers [2,3] have combined the techniques of the Lyapunov method and the nonlinear variation of parameters to study the effects of perturbations of ...
    • Volterra Integral Equations in Abstract Cones and Monotone Iterative Technique 

      Shendge, G. R. (University of Texas at ArlingtonDepartment of Mathematics, 1983-08)
      **Please note that the full text is embargoed** ABSTRACT: The objective of this paper is to develop monotone technique for obtaining extremal solutions of Volterra integral equations in abstract Banach spaces via coupled ...
    • Weight Modules Of Orthosymplectic Lie Superalgebras 

      Ferguson, Thomas Lynn
      A long-standing problem in representation theory is the classification of all simple weight modules of the classical Lie superalgebras. This problem was reduced to the classification of simple bounded highest weight ...
    • WEIGHTED UPWINDING COMPACT SCHEME FOR SHOCK CAPTURING 

      Al-Dujaly, Hassan Abd; 0000-0002-2052-9396 (2017-05-03)
      The Weighted Upwinding Compact Scheme in this dissertation has been constructed due to dissipation and dispersion analysis at each stencil. The new scheme is applied to many one-dimensional typical problems involving ...
    • Zeros of Bouligand-Nagumo Fields, Flow-Invariance and the Bouwer Fixed Point Theorem 

      Pavel, Nicolae H. (University of Texas at ArlingtonDepartment of Mathematics, 1987)
      **Please note that the full text is embargoed** ABSTRACT: Mainly, in this paper we prove that if D is a convex compact of Rn, then the Brouwer fixed point property of D is equivalent to the fact that every Bouligand-Nagums ...
