A Survey of Techniques for Determining Lower Confidence Bounds on Series System Reliability Based on Subsystem Test Data
(University of Texas at ArlingtonDepartment of Mathematics, 1975-09)**Please note that the full text is embargoed** ABSTRACT: A problem of considerable interest and for which a great deal of research has been expended is that of determining lower confidence bounds on series system ... -
System Identification of Models Exhibiting Exponential, Harmonic and Resonant Modes
(University of Texas at ArlingtonDepartment of Mathematics, 1978)**Please note that the full text is embargoed** ABSTRACT: A classical problem arising in compartmental analysis is the so called identification problem or the inverse problem. One is presented with the linear time invariant ... -
System Identification Problems and the Method of Moments
(University of Texas at ArlingtonDepartment of Mathematics, 1977-05)Let X(t) and W(t) be vectors of dimension N > 0. We are concerned with the problem of computing an N x N matrix A such that [see pdf for notation](1.1) where X'(t) is the rate of change of X(t) with respect to time t. ... -
Systems by the Method of Quasisolutions
(University of Texas at ArlingtonDepartment of Mathematics, 1981-01)**Please note that the full text is embargoed** ABSTRACT: Recently [10] the method of lower and upper solutions has been extended to systems of reaction diffusion equations which has become very useful in dealing with ... -
A Systems-Theory Approach to the Analysis of Multiexponential Fluorescence Decay
(University of Texas at ArlingtonDepartment of Mathematics, 1978-08)**Please note that the full text is embargoed** ABSTRACT: A mathematical model of the fluorescence decay experiment based on linear systems theory is presented. The model suggests an experimental technique which increases ... -
A Technic in Perturbation Theory
(University of Texas at ArlingtonDepartment of Mathematics, 1974-07)**Please note that the full text is embargoed** ABSTRACT: A study of the effect of perturbations of differential equations depends on the method employed and on the nature of perturbations. One of the most used technics ... -
A Technique in Stability Theory of Delay-Differential Equations
(University of Texas at ArlingtonDepartment of Mathematics, 1978-04)**Please note that the full text is embargoed** ABSTRACT: In the study of stability theory for delay-differential equations using Lyapunov functions and the theory of differential inequalities, it becomes necessary to ... -
A Temperature-Adjusted Ozone Attainment Criterion Based on Extreme Value Regression Analysis
(University of Texas at ArlingtonDepartment of Mathematics, 1993)**Please note that the full text is embargoed** ABSTRACT: We propose a new statistical methodology to adjust observed peak ozone levels to "normal" meteorology (say, temperatures) across the year for a given site. The ... -
Tennis, Geometric Progression, Probability and Basketball
(University of Texas at ArlingtonDepartment of Mathematics, 1999-03)The following problem about a tennis match is well—known. See Halmos [1, 2]. Consider 2n tennis players playing a single elimination match. Ask the question: what are the number of games played? The answer can be obtained ... -
Tensor Products of a Finite-Dimensional Representation and an Infinite-Dimensional Representation
(2016-05-05)In this project, we explicitly find the decomposition of the tensor product of a Verma module $Z(\lambda)$ and the standard module ${\mathbb C}^n$ of the Lie algebras $\mathfrak{sl}(n)$, $n=2,3$. The result provides an ... -
Testing Exponentiality Against IDMRL Distributions with Unknown Change Point
(University of Texas at ArlingtonDepartment of Mathematics, 1991)**Please note that the full text is embargoed** ABSTRACT: Guess, Hollander and Proschan (1986) proposed tests for exponentiality versus IDMRL (increasing initially and then decreasing mean residual life) distributions when ... -
Testing The Equality Of Regression Coefficients And A Pooling Methodology From Multiple Samples When The Data Is Multicollinear
(Mathematics, 2009-09-16)Testing the equality of regression coefficients between two regression equations is a common practice in statistics today. The theory and methods are sufficiently developed under ordinary least squares (OLS) estimation. ... -
The Natural Middle of a Complete Resolution
(2021-08-23)It is widely known that minimal free resolutions of a module over a complete intersection ring have nice patterns that arise in their Betti sequences. In the late 1990's Avramov, Gasharov and Peeva defined a new class of ... -
THREE DIMENSIONAL IMAGE RECONSTRUCTION (3DIRECT) OF SPARSE SIGNALS WITH MRI APPLICATION
(2016-11-29)Sparse signal reconstruction has been steadily gaining tremendous attention, specifically in applications of compressed sensing as well as feature selection in signal processing methods [IEEE Signal Processing, Vol. 25 ... -
