    • Arbitrary Order, Hamiltonian Conserving Numerical Solutions of Calogero and Toda Systems 

      Greenspan, Donald; Marciniak, Andrzej (University of Texas at ArlingtonDepartment of Mathematics, 1990)
      For Calogero and Toda dynamical equations two numerical methods of arbitrary high order, conserving the Hamiltonian are developed. The methods consist of modifications of conventional polynomial extrapolation with the Gragg ...
    • An Arithmetic Computer Approach to Gas Dynamical Modeling 

      Greenspan, Donald; Wadia, Aspi Rustom (University of Texas at ArlingtonDepartment of Mathematics, 1979-01)
      Unsteady, two dimensional internal and external flows are analyzed using an arithmetic n-body formulation. A Lagrangian approach is used to study the internal shock formation in a shock tube and the external flows over a ...
    • Asymptotic Equilibrium of Ordinary Differential Systems in a Banach Space 

      Mitchell, Roger W.; Mitchell, A. Richard (University of Texas at ArlingtonDepartment of Mathematics, 1974-03)
      A differential system [see pdf for notation] where [see pdf for notation] has asymptotic equilibrium if 1) for any initial condition [see pdf for notation] the system has a solution [see pdf for notation] existing on and ...
    • Asymptotic Properties of a Nonlinear Diffusion Process Arising in Articular Cartilage 

      Mow, Van C.; Eisenfeld, Jerome (University of Texas at ArlingtonDepartment of Mathematics, 1977-01)
      There has been considerable effort put forth to analyse degenerative Joint diseases in terms of the principles of mechanics and hydrodynamics [8]. This effort has led to mathematical models which are systems of nonlinear ...
    • An Asymptotic Result in Forced Oscillations of Pendulum-Type Equations 

      Kannan, R.; Ortega, R. (University of Texas at ArlingtonDepartment of Mathematics, 1985-04)
      The forced pendulum-type equation is given by [see pdf for notation] where [see pdf for notation] is continuous and T-periodic and p(t) is[see pdf for notation] -periodic. When g(x) = a sin x, a > 0, we obtain the classical ...

    • An Average Per Capita Formula for the Shapely Value 

      Dragan, Irinel C. (University of Texas at ArlingtonDepartment of Mathematics, 1992-09)
      A new formula for the Shapley value is given which does not require the storage of the [see pdf for notation] values of the characteristic function in the computer, and avoids the search in the memory for such data.
    • Banzhaf Permission Values for Games with Permission Structure 

      van den Brink, Rene (University of Texas at ArlingtonDepartment of Mathematics, 2000-05)
      A game with a permission structure describes a situation in which cooperation possibilities in a cooperative game with transferable utility are limited because there are players that need permission from other players ...
    • Bargaining Sets with Thresholds 

      Dragan, Irinel C. (University of Texas at ArlingtonDepartment of Mathematics, 1984-02)
      A concept of bargaining set for cooperative n person games with side payments has been defined by assuming that a player could be attracted in a new coalition only if his supplementary gain exceeds a fixed threshold and ...
