Parabolic Differential Inequalities in Cones
(University of Texas at ArlingtonDepartment of Mathematics, 1978-03)**Please note that the full text is embargoed** ABSTRACT: In this paper we investigate the theory of parabolic differential inequalities in arbitrary cones. After discussing the fundamental results concerning parabolic ... -
Parameter Estimation in Illness-Death Processes: Preinfaractional Angina
(University of Texas at ArlingtonDepartment of Mathematics, 1979)**Please note that the full text is embargoed** ABSTRACT: An illness-death process is an absorbing Markov process where the illness states from the transient states of the process. This paper deals with the estimation of ... -
A Particle Model of Ground State H2
(University of Texas at ArlingtonDepartment of Mathematics, 1990-06)**Please note that the full text is embargoed** ABSTRACT: A particle model is developed for the ground state H2 molecule. Interparticle forces are formulated which are noncoulombic, but nearly coulombic. The vibration ... -

Particle Simulation in Contact Mechanics of a Bouncing Elastic Ball
(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 ... -
Particle Simulation of Biological Sorting on a Supercomputer
(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, ... -
Particle Simulation of Compression Waves
(University of Texas at ArlingtonDepartment of Mathematics, 1984-05)**Please note that the full text is embargoed** ABSTRACT: Compression waves are studied using a quasi-molecular, particle approach. Explosive type disturbances are simulated to generate such waves, which propagate by the ... -
Particle Simulation of Large Carbon Dioxide Bubbles in Water
(University of Texas at ArlingtonDepartment of Mathematics, 1993)**Please note that the full text is embargoed** ABSTRACT: A method which can be applied to simulate the motion of fluid drops within fluids is described through a detailed study of a prototype problem, that is, the motion ... -
Particle Simulation of Spiral Galaxy Evolution
(University of Texas at ArlingtonDepartment of Mathematics, 1985)**Please note that the full text is embargoed** ABSTRACT: Spiral galaxies are modelled as n-body systems by means of long range and molecular-type short range forces. A relatively massive, elliptic, type core is sit into ... -
