#### Pressure Method for the Numerical Solution of Transient, Compressible Fluid Flown

(University of Texas at Arlington, 1983-08)

In this paper the pressure method for incompressible fluid flow simulation is extended and applied to the numerical simulation of compressible fluid
flow. The governing equations, obtained from the physical principles ...

#### Melting Points of Atomic and Homogeneous, Diatomic Molecular Solids Via the Four-Body Problem

(University of Texas at Arlington, 1992-10)

For a regular tetrahedral arrangement of four identical atoms, the minimum velocity of one atom, required for that atom to pass through the plane of the other three, is used to define the melting point of any solid composed ...

#### Particle Simulation of Compression Waves

(University of Texas at Arlington, 1984-05)

Compression waves are studied using a quasi-molecular, particle approach. Explosive type disturbances are simulated to generate such waves, which
propagate by the interaction of each particle with its immediate neighbors. ...

#### Particle Simulation of Large Carbon Dioxide Bubbles in Water

(University of Texas at Arlington, 1993)

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 of carbon dioxide bubbles in water. The mathematical ...

#### Particle Modeling of Unstable Mode Configurations and Elastic Bending of Deformable Shells

(University of Texas at Arlington, 1984)

A new particle-type of modeling is developed for the simulation of phenomena related to the bending of elastic shells. Application is
made to the determination of unstable equilibrium modes and to the simulation of ...

#### A Particle Model of Ground State H2

(University of Texas at Arlington, 1990-06)

A particle model is developed for the ground state H2 molecule.
Interparticle forces are formulated which are noncoulombic, but
nearly coulombic. The vibration is simulated by a numerical
method which conserves the ...

#### On Nonlinear Parameter Estimation in Least Squares Approximation

(University of Texas at Arlington, 1993-03)

A non-matrix form of Newton's method for systems of nonlinear
equations is described for nonlinear parameter estimation in
least squares approximation. Computer examples are described
and discussed for the exponential ...

#### N-Body Modeling of Nonlinear, Free Surface Liquid Flow

(University of Texas at Arlington, 1978-11)

In this paper a new, n-body approach is developed for the
modeling of liquid phenomena. Both long and short range forces
are included. Computer examples of several prototype, nonlinear,
free surface problems are ...

#### A Semiclassical, Dynamical Model of the Water Molecule

(University of Texas at Arlington, 1995)

A model of the ground state water molecule is formulated dynamically and studied by computer simulations. Excellent approximations of NMR determined bond angles and bond lengths are achieved through electron pairing and ...

#### Local Molecular Temperature

(University of Texas at Arlington, 1989-11)

For the study of phase-transition by molecular dynamics, the concept of local temperature is desirable. Such a concept, defined and studied previously for atoms, is extended in this paper to molecules. The fundamental ...
