(Wichita State University, 193305) 
An analysis of the replies to the Kansas American Association of University Women's questionnaire on teacher welfare
(Wichita State University, 194805) 
Elementary applications of matrices
(Wichita State University, 194807)This treatise is concerned principally with the fundamental properties of matrices, the basic operations which may be performed with them, and some of their applications to algebra, analytic geometry, and differential ... 
The construction of revised objective final examination in statistics
(Wichita State University, 194905)During the past three years an examination constructed by Dr. C. B. Read, head of the mathematics department of the University of Wichita, has been given to 597 students as the final examination in beginning statistics ... 
Infinite products
(Wichita State University, 195306) 
Topics in theory of numbers
(Wichita State University, 195405) 
A brief treatise on the Joukowski transformation
(Wichita State University, 195406)The problem of predicting the flight characteristics of an arbitrary airfoil is very complicated, and does not readily lend itself to exact mathematical methods. However if certain simplifying assumptions are made the ... 
Selected methods of matrix inversion
(Wichita State University, 195605)Matrix theory is concerned with the study of rectangular arrays of elements called matrices . In this paper, except for one example, no attempt will be made to describe how these arrays are obtained originally nor to ... 
A set of exercises to be used with Dr. C. B. Read's Manual of Statistics
(Wichita State University, 195606)A need has been expressed for an extensive set of problems which may be used as a supplement to the text and which can be used for both courses in statistics. It is the purpose of this study to develop such a set of ... 
A strong law of large numbers for nonparametric regression
(Academic Press, 1989071)Suppose (i1,n, ..., in,n) is permutation of (1, ..., n) for each positive integer n such that the order of the indices {1, h., n  1} in the permutation corresponding to n  1 is preserved. If {Zn} is a sequence of meanzero ... 
Pole placement by linear quadratic modification for continuous time systems
(IEEE, 19910626)This paper bridges the gap between linear quadratic solution and pole placement providing a simple criterion sucht that the resulting optimal gain places the closed loop eigenvalues at desired locations. The method has the ... 
Constrained pole placement by linear quadratic modification
(IEEE, 19910626)A noniterative method is introduced that will enable the designer to find an optmal one step state feedback controller. The controller will place the eigenvalues of the closed loop system in a specified disk. 
Numerical comparison of negative damping bounds in a specified domain when the wave speed varies
(IEEE, 19920624)The energy decay of a selfexcited wave equation utt  c2 Â¿ u  P(x)ut = 0 is studied where the wave speed c is greater than one, P(x) Â¿ 0, and P(x) LÂ¿(Â¿), Â¿ Â¿ Â¿ Rn. Moreover, the relationship between two bounds for ... 
The stabilization of a linearized selfexcited wave equation by an energy absorbing boundary

Stability of coupled strings vibration system due to different boundary conditions
(IEEE, 19930602)We study the rate of convergence of a coupled wave systems under two different boundary conditions, energy absorbing in two ends for one and free or fixed boundary controls in two ends for the other one. We will observe ... 
Reinforcement and backpropagation training for an optical neural network using selflensing effects
(IEEE, 200011)The optical bench training of an optical feedforward neural network, developed by the authors, is presented. The network uses an optical nonlinear material for neuron processing and a trainable applied optical pattern as ... 
Application of the limit of truncated isotonic regression in optimization subject to isotonic and bounding constraints
(Academic Press Inc., 20020525)An isotonic regression truncated by confining its domain to a union of its level sets is the isotonic regression in the reduced function space. When some of the weights with which the inner product system is defined go to ...
