Analytical and Numerical Studies on the States of Ions and Atoms
(University of Texas at Arlington, 1985)
**Please note that the full text is embargoed** ABSTRACT: A speculative model is described which refines and extends the method of Bohr to various atoms and ions which have four or fewer electrons. The results for ground, ...
Rapid Computation of the Energy States of Two-Electron Systems
(University of Texas at Arlington, 1985)
**Please note that the full text is embargoed** ABSTRACT: A new deterministic approach to modelling atoms and molecules is developed which uses static and dynamic numerical methods. The estimate for the ground state energy ...
A New Algorithm for Unstable Three Terms Recurrence Relations
(University of Texas at Arlington, 1985-09)
**Please note that the full text is embargoed** ABSTRACT: A modified version of Miller's and Olver's algorithm based on the "double sweep" method is presented. It is very stable in both directions and automatically controls ...
Rapid Approximation of the Energy States of Three-Electron Systems
(University of Texas at Arlington, 1985-03)
**Please note that the full text is embargoed** ABSTRACT: In this paper, we show how to approximate rapidly the energy states of systems with one electron in the second ring. Using known energy states and average radii of ...
Remarks on Bellman's Structural Identifiability
(University of Texas at Arlington, 1985-03)
**Please note that the full text is embargoed** ABSTRACT: This paper remarks on unidentifiable compartmental systems. Emphasis is placed on detecting properties of the system directly from the compartmental diagram without ...
Multivalued Maps and Multivalued Differential Equations
(University of Texas at Arlington, 1985-04)
**Please note that the full text is embargoed** ABSTRACT: Everybody meets multivalued maps very early in his mathematical education, as inverses of maps which are not one-to-one, but in elementary lectures the multivalued ...
Particle Simulation of Spiral Galaxy Evolution
(University of Texas at Arlington, 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 ...
Numerical Simulation of Miscible and Immiscible Fluid Flows in Porous Media
(University of Texas at Arlington, 1981-02)
**Please note that the full text is embargoed** ABSTRACT: Fast, economical, and accurate finite difference numerical methods are developed for approximating continuum
models of both miscible and immiscible fluid flows ...
Linear Monotone Method for Nonlinear Boundary Value Problems in Banach Spaces
(University of Texas at Arlington, 1981-05)
**Please note that the full text is embargoed** ABSTRACT: One of the most useful techniques in proving the existence of multiple solutions of nonlinear boundary value problems (BVP for short) is the
monotone iterative ...
On Washout in Nonlinear Compartmental Systems
(University of Texas at Arlington, 1981-04)
**Please note that the full text is embargoed** ABSTRACT: 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 ...
