Parabolic Differential Inequalities In Cones, Randy Vaughn, V. Lakshmikantham Mar 1978

Parabolic Differential Inequalities In Cones, Randy Vaughn, V. Lakshmikantham

Mathematics Technical Papers - Archive

In this paper we investigate the theory of parabolic differential inequalities in arbitrary cones. After discussing the fundamental results concerning parabolic inequalities in cones, we prove a result on flow-invariance which is then used to obtain a comparison theorem. This comparison result is useful in deriving upper and lower bounds on solutions of parabolic differential equations in terms of the solutions of ordinary differential equations. We treat the Dirichlet problem in this paper since its theory follows the general pattern of ordinary differential equations and requires less restrictive assumptions. The treatment of Neumann problem, on the other hand, demands stronger …


A Further Look At The Comparison Of Normal Percentile Estimators, Danny D. Dyer Mar 1978

A Further Look At The Comparison Of Normal Percentile Estimators, Danny D. Dyer

Mathematics Technical Papers - Archive

For the purpose of making a pairwise comparison of point estimators of normal percentiles, a twofold technique is introduced which basically examines ,(a) the "odds" in favor of an estimator being closer to the true value than is a competing estimator and (b) an estimator's average closeness to the true value when it is closer (as well as when it is not) than is a competing estimator. Closeness to the true value is measured through an absolute error loss function. Joint consideration of these concepts is shown to form a basis for determining which of two estimators is preferred in …

Reaction-Diffusion Inequalities In Cones, Randy Vaughn, V. Lakshmikantham Feb 1978

Reaction-Diffusion Inequalities In Cones, Randy Vaughn, V. Lakshmikantham

Mathematics Technical Papers - Archive

Recently there has been a growing interest in the study of nonlinear reaction-diffusion equations [2,3,4,7] because of the fact examples of such equations occur in population genetics [2,5,12,13], nuclear and chemical reactors [2,7,8], conduction of nerve impulses [1,7,15], and several other biological models [1,6,15]. As is the case of ordinary differential equations [9,10], it is natural to expect that the theory of reaction-diffusion inequalities and comparison theorems will play a prominent role in this study. In this paper, we consider reaction-diffusion equations which are weakly coupled relative to an arbitrary cone. We prove a result on flow-invariance which is then …

System Identification Of Models Exhibiting Exponential, Harmonic And Resonant Modes, B. Soni, Jerome Eisenfeld Jan 1978

System Identification Of Models Exhibiting Exponential, Harmonic And Resonant Modes, B. Soni, Jerome Eisenfeld

Mathematics Technical Papers - Archive

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 compartmental model [see pdf for notation] [see pdf for notation] Where A is a square matrix and the dimensions of B and C are consistent with that of A. The problem is to estimate a certain subset of the matrix elements [see pdf for notation], [see pdf for notation] and [see pdf for notation] from discrete observations of the input vector u(t) and the output vector y(t). When instantaneous mixing is assumed the analogous equations …


Relationship Between Stochastic And Differential Models Of Compartmental Systems, Jerome Eisenfeld Jan 1978

Relationship Between Stochastic And Differential Models Of Compartmental Systems, Jerome Eisenfeld

Mathematics Technical Papers - Archive

This paper shows that the differential equations model for compartmental systems is consistent with a stochastic description. Consequently, we may employ either a differential equations or a stochastic formulation for either parameter identification, or for physical interpretation, as best suits the purpose. The differential equations parameters, the so-called fractional transfer coefficients, may be determined from the corresponding set of stochastic parameters and vice versa.

Competitive-Cooperative Processes And Stability Of Diffusion Systems, V. Lakshmikantham, G. S. Ladde Jan 1978

Competitive-Cooperative Processes And Stability Of Diffusion Systems, V. Lakshmikantham, G. S. Ladde

Mathematics Technical Papers - Archive

Very recently, the stability analysis of deterministic [12], random [12,13] competitive-cooperative process has been made in a systematic and unified way. It is well recognized that the probabilistic models in biological [7,9,19,20,30], physical [7,20,21,30], and social [31] sciences are more realistic than the deterministic models. In this paper, we extend the stability analysis of random competitive-cooperative processes [11] to the stability analysis of competitive processes of the diffusion type. The stability results presented includes the stability analysis of multispecies community models [16,17] under white-noise excitations. All our results are in the frame-work of the earlier results [11-13, 16-18]. The paper …

The Functions Of Reported Speech In Discourse, Mildred Lucille Larson Dec 1977

The Functions Of Reported Speech In Discourse, Mildred Lucille Larson

Linguistics & TESOL Dissertations - Archive

The study of the functions of reported speech makes five ma­jor contributions to the current literature on discourse. (l) It highlights the multifunctional characteristics of reported speech; (2) it correlates these functions with discourse types; (3) it points out the necessity to separate the situational features from the deep structure organizational features and relates both to surface structure discourse types; (4) it defines more clearly the nature of dialogue discourse, that of a portmanteau realization of deep structure narrative and repartee; and (5) it shows for the first time within the stratificational grammar framework that contrastive discourse structures occur both …


Monotone Methods For Nonlinear Boundary Value Problems In Banach Spaces, Stephen R. Bernfeld, V. Lakshmikantham Dec 1977

Monotone Methods For Nonlinear Boundary Value Problems In Banach Spaces, Stephen R. Bernfeld, V. Lakshmikantham

Mathematics Technical Papers - Archive

Monotone methods have been used to generate multiple solutions of nonlinear boundary value problems for both ordinary and partial differential equations. Keller [10] and Sattinger [13], extending the chord method, considered nonlinear partial differential equations containing no gradient term. The inclusion of the gradient term was first introduced by Chandra and Davis [6] who considered the ordinary boundary value problem (1.1) [see pdf for notation] (1.2) [see pdf for notation] Here [see pdf for notation]. They assumed that f depends linearly on [see pdf for notation]; and this restriction on [see pdf for notation]' was eliminated by Bernfeld and Chandra …

Remarks On Numerical Computations Using The Alternative Method, R. Kannan, Jerome Eisenfeld, Stephen R. Bernfeld

Mathematics Technical Papers - Archive

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 boundary value problems. Our purpose here is to point out how these approximations may be improved upon without much additional effort. For illustrative purposes we discuss one of their examples.


Fixed Point Theorem For Non-Expansive Mappings On Banach Spaces With Unifformly Normal Structure, B. B. Williams, A. A. Gillespie Nov 1977

Fixed Point Theorem For Non-Expansive Mappings On Banach Spaces With Unifformly Normal Structure, B. B. Williams, A. A. Gillespie

In [1] Kirk proved that if D is a bounded, closed, and convex subset of a reflexive Banach space that has normal structure, then every non-expansive mapping of D into D has a fixed point. This was also proved for a uniformly convex space by Browder [2]. In this paper we replace uniformly convex, or reflexive and normal structure, by uniformly normal structure to obtain this result. Let S be a bounded subset of the Banach space X and [see pdf for notation] (1) [see pdf for notation] (2) [see pdf for notation] (3) [see pdf for notation] A space …


Pitman-Closeness Efficiency Of Estimators Of Reliability With Application To The Exponent/Al Failure Model, Jerome P. Keating, Danny D. Dyer Oct 1977

Pitman-Closeness Efficiency Of Estimators Of Reliability With Application To The Exponent/Al Failure Model, Jerome P. Keating, Danny D. Dyer

Mathematics Technical Papers - Archive

When there are available several point estimators of component or system reliability, it would be of interest to compare such estimators through some "closeness to the true value of reliability" criteria. Along these lines, the concept of Pitman-closeness efficiency is introduced. Essentially, when comparing two estimators of reliability for a given situation, Pitman-closeness efficiency gives the odds in favor of one of the estimators being closer to the true value of reliability than is the other. Theory is developed which provides a straightforward way to evaluate this measure of efficiency under fairly general conditions on the estimators. Based on this …
