#### A Mathematical Curiosity in Estimating the Radius of the First Ring Electrons of an Arbitary Atom

(University of Texas at Arlington, 1984)

In this note, we explore an elementary method for approximating the radii and speeds of first ring electrons in atoms. The approach uses only a single
algebraic equation with parameters. Any particular atom under study ...

#### 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 ...

#### Method of Quasi-Upper and Lower Solutions in Abstract Cones

(University of Texas at Arlington, 1981-05)

Let E be a real Banach space with ||•|| and let E* denote the dual of E. Let K C E be a cone, that is, a closed convex subset such
that ^K C K for every ^ ≥ 0 and K ^ {-K} = {O}, By means of K a partial order ≤ is defined ...

#### Interval Estimation of the Noncentrality Parameter of A Gamma Distribution

(University of Texas at Arlington, 1984-09)

Asymptotic confidence interval for the noncentrality parameter of a Gamma distribution (or Chi-squared distribution) is derived. An algorithm for
computing the maximum likelihood estimator of the non-centrality parameter ...

#### Programs and Data Sets for Quasimolecular Modeling of Cavity Flow

(University of Texas at Arlington, 1987-01)

#### On Washout in Nonlinear Compartmental Systems

(University of Texas at Arlington, 1981-04)

Let x(t) be a solution of a compartmental system. If, for some compartment j, x (t) -> 0 as t -> °°, then we say that compartment
j washes out. We show that a compartment washes out if it always reaches (along a fixed ...

#### Existence and Monotone Method for Periodic Solutions of First Order Differential Equations

(University of Texas at Arlington, 1981-09)

An attempt was made recently in [3] to combine fruitfully the two basic techniques, namely the method of upper and lower solutions and the Lyapunov-Schmitt
method to investigate the existence of periodic solutions of ...

#### Monotone Method for Equations Describing Transport Phenomena in a Banach Space

(University of Texas at Arlington, 1981-06)

Existence of extremal solutions of initial and boundary value problems (B.V.P. for short) of differential equations in a Banach
space has been recently considered in [2,7] by utilizing monotone iterative method.
A ...

#### Monotone Iterative Technique for Delay Differantial Equations in Abstract Cones

(University of Texas at Arlington, 1982-04)

Monotone iterative technique is developed for delay differential equations
in a Banach space by utilizing the method of upper and lower solutions.

#### Numerical Simulation of Miscible and Immiscible Fluid Flows in Porous Media

(University of Texas at Arlington, 1981-02)

Fast, economical, and accurate finite difference numerical methods are developed for approximating continuum
models of both miscible and immiscible fluid flows in porous media. The methods apply to very general systems ...
