#### Linear Algebraic Computational Procedures for System Identification Problems

(University of Texas at Arlington, 1977-05)

An algorithm is presented for identifying exponentials sums [see pdf for notation] from discrete data [see pdf for notation] The algorithm determines
the number of components, [see pdf for notation] the rate constants ...

#### Mathematical Analysis of Stress Relaxation in Articular Cartilage During Compression

(University of Texas at Arlington, 1977-02)

Articular cartilage is the avascular bearing material covering the articulating ends of the mating bony segments of synovial joints. Functionally articular cartilage provides a near frictionless surface, whose coefficient ...

#### General Moment Methods for a Class of Nonlinear Models

(University of Texas at Arlington, 1977)

This paper deals with the following problems: (i) the development of a general theory which incorporates several methods as special cases; (ii) the applicability of moment methods to a class of nonlinear
problems, (iii) ...

#### Estimating Transition Probabilities from Aggregate Samples Augmented by Haphazard Recaptures

(University of Texas at Arlington, 1995)

Transition probabilities provide a convenient summary of changes in a categorical trait over time in a population. The difficulties of estimating such probabilities based on only aggregate data from repeated sampling are ...

#### Remarks on Numerical Computations Using the Alternative Method

(University of Texas at Arlington, 1977-12)

Recently Cesari and Bowman [1] have demonstrated the applicability of the alternative method to obtain approximate solutions of nonlinear equations. They provided numerical approximations of solutions of two point nonlinear ...

#### On the Existence of Solutions of Differential Equations in a Banach Space

(University of Texas at Arlington, 1974-03)

The study of Cauchy problem for differential equations in a Banach space has taken two different directions. One approach is to find compactness type conditions [1,2,4,9,14] to guarantee existence of solutions only and the ...

#### Asymptotic Properties of a Nonlinear Diffusion Process Arising in Articular Cartilage

(University of Texas at Arlington, 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 ...

#### Stochastic Parameters in Compartmental Systems

(University of Texas at Arlington, 1980-05)

Let [see pdf for notation] denote the
probability that a particle in compartment j
will reach (or enter) compartment i. We present
several formulas for obtaining the [see pdf for
notation] in terms of the ...

#### A Direct Computational Method for Estimating the Parameters of a Nonlinear Model

(University of Texas at Arlington, 1978)

We consider the system identification problem which deals with determining information about the unknown constant matrices A, B, and C or the linear dynamical system: [see pdf for notation], where u(t) and y(t) are given ...

#### Differential Inequalities and Flow-Invariance via Linear Functionals

(University of Texas at Arlington, 1977-05)

This paper deals with flow-invariance properties with respect to [see pdf for notation] and resulting comparison inequalities. Both the order relation He and the regularity conditions on x are defined, in a general manner, ...
