  • On the Computation of Semivalues for TU Games 

    Dragan, Irinel (University of Texas at ArlingtonDepartment of Mathematics, 2008-12)
    In an earlier paper, [Dragan,2006a] , we proved that every Least Square Value is the Shapley Value of a game obtained by rescaling from the given game. In the paper where the Least Square Values were introduced by Ruiz, ...
  • Particle Simulation in Contact Mechanics of a Bouncing Elastic Ball 

    Greenspan, Donald (University of Texas at ArlingtonDepartment of Mathematics, 1999-05)
    An elastic ball is simulated by considering lumped mass molecular sets called particles. Particles are allowed to interact only locally in a fashion similar to that employed in molecular mechanics. Under local and gravity ...
  • Molecular Mechanics Simulations of the Three Dimensional Cavity Problem 

    Greenspan, Donald (University of Texas at ArlingtonDepartment of Mathematics, 1999-03)
    The rapid development of computer technology has resulted in broad interest in three dimensional fluid simulation, which is known to have more complex force interactions than occur in two dimensions (see, e.g., refs. [1-6], ...
  • Tennis, Geometric Progression, Probability and Basketball 

    Ghandehari, Mostafa (University of Texas at ArlingtonDepartment of Mathematics, 1999-03)
    The following problem about a tennis match is well—known. See Halmos [1, 2]. Consider 2n tennis players playing a single elimination match. Ask the question: what are the number of games played? The answer can be obtained ...
  • System Identification Problems and the Method of Moments 

    Eisenfeld, Jerome; Cheng, S. W.; Bernfeld, Stephen R. (University of Texas at ArlingtonDepartment of Mathematics, 1977-05)
    Let X(t) and W(t) be vectors of dimension N > 0. We are concerned with the problem of computing an N x N matrix A such that [see pdf for notation](1.1) where X'(t) is the rate of change of X(t) with respect to time t. ...

    **Please note that the full text is embargoed** ABSTRACT: A intermolecular approach is developed for the modeling of sessile and pendent drops. Fundamental mechanisms of drop formation are formulated in terms of gravity ...
  • Absolute Minimization by Supercomputer Computation 

    Greenspan, Donald (University of Texas at ArlingtonDepartment of Mathematics, 1987)
    **Please note that the full text is embargoed** ABSTRACT: Numerical methodology is developed for approximating the absolute minimum of a function or a functional. Only simplistic numerical techniques are introduced and ...
  • Estimating Transition Probabilities from Aggregate Samples Augmented by Haphazard Recaptures 

    Hawkins, D. L.; Eisenfeld, Jerome; Han, C. P. (University of Texas at ArlingtonDepartment of Mathematics, 1995)
    **Please note that the full text is embargoed** ABSTRACT: Transition probabilities provide a convenient summary of changes in a categorical trait over time in a population. The difficulties of estimating such probabilities ...
  • Conservative Difference Formulations of Calogero and Toda Hamiltonian Systems 

    Greenspan, Donald (University of Texas at ArlingtonDepartment of Mathematics, 1988)
    **Please note that the full text is embargoed** ABSTRACT: Calogero and Toda Hamiltonian systems are reformulated using only differences. The formulations prove to have the same fundamental invariants as the continuous ...

    Greenspan, Donald (University of Texas at ArlingtonDepartment of Mathematics, 1988)
    **Please note that the full text is embargoed** ABSTRACT: Cell sorting, or, self reorganization, is modelled by means of particles which obey classical molecular dynamical equations. A system of N second order, nonlinear, ...
  • Heron's Problem in the Minkowski Plane 

    Ghandehari, Mostafa (University of Texas at ArlingtonDepartment of Mathematics, 1995)
    **Please note that the full text is embargoed** ABSTRACT: Heron's problem in the Euclidean plane is that of minimizing the length of a path that joins two points on one side of a line and intersects the line. A ...
