Completion And Compactification Functors For Cauchy Spaces, James Francis Ramaley
Completion And Compactification Functors For Cauchy Spaces, James Francis Ramaley
Mathematics & Statistics ETDs
The subject of this thesis is topological but the approach is categorical. We consider the approach as important as the subject itself and so we try to indicate whenever we have a categorically defined concept. In fact, we are led by this approach to make definitions and constructions so that certain relationships are categorical in nature. Our coreflective completion functor of Chapter IV is one example of this approach.
We wish here to give a brief outline of the historical development of convergence theory and how category theory has come to play a role in this development...
Tolerance Regions For A Joint Exponential Distribution, Lee J. Bain
Tolerance Regions For A Joint Exponential Distribution, Lee J. Bain
Mathematics and Statistics Faculty Research & Creative Works
The evaluation of the reliability of a system of components, when the components are assumed to follow a joint exponential distribution, is considered. The approach used is to develop tolerance regions for the joint exponential distribution or to estimate the probability content of the appropriate specification region.

A Survey Of The Applications Of Difference Equations, Roberta Lanice Harkey
A Survey Of The Applications Of Difference Equations, Roberta Lanice Harkey
Mathematics & Statistics ETDs
In asserting that people in other fields often tend to be afraid to use mathematics, F.K. Mechta, an economist, expressed an uncertainty which contributes to the hesitancy to use mathematics. “Mathematics is tricky, it maintains silence, does its work quietly; and when we do not understand its ways and misinterpret its message, it just smiles. It never loses its temper, never laughs; we can observe a suppressed smile on its lips. Such is mathematics.” It is the purpose of this paper to conduct a brief survey of the applications of difference equations. The use of these equations is often rather …
Simulation Of Mathematical Models In Genetic Analysis, Dinesh Govindal Patel
Simulation Of Mathematical Models In Genetic Analysis, Dinesh Govindal Patel
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In recent years a new field of statistics has become of importance in many branches of experimental science. This is the Monte Carlo Method, so called because it is based on simulation of stochastic processes. By stochastic process, it is meant some possible physical process in the real world that has some random or stochastic element in its structure. This is the subject which may appropriately be called the dynamic part of statistics or the statistics of "change," in contrast with the static statistical problems which have so far been the more systematically studied. Many obvious examples of such processes …
Some Information - Theoretical And Empirical Techniques In Statistical Inference, Chaitanya Swarup
Some Information - Theoretical And Empirical Techniques In Statistical Inference, Chaitanya Swarup
Mathematics & Statistics ETDs
This study is divided into two seemingly disjoint parts -- one containing EMPIRICAL (Bayesian and Non-Bayesian) approach and the second containing INFORMATION-THEORETICAL techniques in problems of statistical estimation and tests of hypotheses. But in the end, both approaches have been brought together for solving ENCODING problems of COMMUNICATION THEORY to unify the whole dissertation.
Some Properties Of Certain Sets Of Coprime Integers, Roger C. Entringer
Some Properties Of Certain Sets Of Coprime Integers, Roger C. Entringer
Mathematics & Statistics ETDs
The set P(n) of all primes equal to or less than n has the obvious property that it contains exactly one multiple of each prime equal to or less than n. We use this partial description of P(n) as a basis for the following
Definition 1.1. An increasing sequence {a1,...,ak} of integers greater than 1 is a coprime chain if it contains exactly one multiple of each prime equal to or less than ak.
Convergence Functions And Their Related Topologies, Darrell C. Kent
Convergence Functions And Their Related Topologies, Darrell C. Kent
Mathematics & Statistics ETDs
A convergence function is a correspondence between the filters on a given set S and the subsets of S which specifies which filters converge to which points of S. This concept is defined to include types of convergence which are more general than that defined by specifying a topology on S. Thus a convergence function may be regarded as a generalization of a topology.
A Statistical Technique For Predicting A Two Dimensional Vector With Application, Richard E. Vogel
A Statistical Technique For Predicting A Two Dimensional Vector With Application, Richard E. Vogel
Mathematics & Statistics ETDs
The problem of multiple regression analysis where the dependent and independent variables are components of a two dimensional vector is discussed, and a complete statistical development of the solution of estimators for the parameters in the model given. The theory regarding predictions and confidence statements about such predictions is also developed. A computer code was written for the IBM 704 computer which solves the above problem and a description of the code appears in the appendix.
The statistical model was applied to a meteorological problem in wind forecasting at the Eniwetok Proving Ground, and prediction equations were developed and evaluated.
Beta And Gamma Distributions, Calvin Rogers
Beta And Gamma Distributions, Calvin Rogers
Mathematics & Statistics ETDs
The purpose of this paper is to exhibit the main properties of Gamma and Beta distributions and show their relation to certain well known distributions.
In chapter II the Gamma and Beta distributions are defined in terms of Gamma and Beta functions. The moments of these distributions are calculated, and the moment generating function and cumulant generating function for the Gamma distribution are obtained. The curves are classified with respect to parameter values and the curves are graphically illustrated in Figures 1, 2, and 3. The exponential distribution, as a special case of interest, is shown to be a Gamma …
The Use Of Kamke's Transformation In Approximating The Zeros Of Orthogonal Polynomials, Robert L. Daniels
The Use Of Kamke's Transformation In Approximating The Zeros Of Orthogonal Polynomials, Robert L. Daniels
Mathematics & Statistics ETDs
The importance of the classical orthogonal polynomials has long been acknowledged. It has not been possible, however, to represent them in such a way that all of their important properties are immediately evident. In particular, the location of the zeros of these polynomials is of considerable interest.
This thesis is primarily concerned with a different technique in which Kamke's transformation is applied to the differential equations frequently used to define these polynomials. The resulting trigonometric differential equations cannot be explicitly solved either, but certain characteristics of these solutions facilitate the derivation of approximations to the zeroes of the solutions.
The Variation Problems Of Weierstrass-Bliss And Radon, Douglas M. Gragg
The Variation Problems Of Weierstrass-Bliss And Radon, Douglas M. Gragg
Mathematics & Statistics ETDs
Problems of the Calculus of Variations are generalizations of the familiar minimum problems treated in the differential calculus. The relationships between the ordinary minimum problems of the calculus and the generalizations dealt with in the Calculus of Variations is possibly best seen by examining the general Hilbert-Moore minimum problem, and the special examples of such problems formulated in the table below.

Inverse Problems Of Hamel-Type., Robert G. Schrandt
Mathematics & Statistics ETDs
The formulation and discussion of the simplest (fixed) end point direct problem of the calculus of Variation is a necessary preliminary to attack on the inverse problems considered in Chapters II and III of this thesis. Since the plane problem is already comprehensively treated in the literature, only enough of its theory is developed here to render intelligible to the reader the inverse problems studied in the sequel.
The Darboux Inverse Problem In The Calculus Of Variations, Frank O. Lane
The Darboux Inverse Problem In The Calculus Of Variations, Frank O. Lane
Mathematics & Statistics ETDs
The simplest non-parametric problem of the calculus of variation, the so-called direct problem of the plane, is the problem of finding that arc Co of a family of admissible arcs y=y (x) joining two fixed pointed (x1 , y1 ), (x1, y2) in the x,y-plane such that along the Co the integral takes on a minimum value.

The purpose of this study is to investigate the nature of the coefficients of certain power series. In particular, it is desired to know what characteristics the coefficients must possess in order that the series shall represent an entire function.
Studies Arising From A Problem In The Calculus Of Variations, John Gonzalez
Studies Arising From A Problem In The Calculus Of Variations, John Gonzalez
Mathematics & Statistics ETDs
In mathematics, generalization is progress; so much so that oftentimes one loses sight of the fact that generalization is the result of arduous work in the consideration of the particular. In no other branch of mathematics is this better exemplified than in the Calculus of Variations. The beginning of a systematic development of the theory of the Calculus of Variations really started with the two Bernoulli brothers (1654-1748) in their discussion of the brachistochrone problem in 1696. The method devised by them were sufficiently powerful in the attack of a large number of problems. Euler (1707-85) further elaborated the geometrical …
The Evolution Of The Concept Of Axiom, William Fred Jones
The Evolution Of The Concept Of Axiom, William Fred Jones
Mathematics & Statistics ETDs
The field of knowledge known as mathematics is composed of the totality of mathematical systems. A mathematical system consists of a body of propositions known as the axioms. The concern of this paper is with the axioms; in fact, with the change which has taken place during the centuries in the ideas of mathematicians about the axioms.
New Formulae For The Determination Of The Yield Of A Bond, Marvin Roberts
New Formulae For The Determination Of The Yield Of A Bond, Marvin Roberts
Mathematics & Statistics ETDs
A written contract to pay a certain amount of money on a specified redemption date, and to pay equal periodical dividends, is called a bond from a mathematical standpoint. The principal mentioned in the contract is its face value, or par value. The amount redeemed, or the redemption value, is denoted by C, the dividends by D, and the principal by F. A bond is redeemed at a par if C and F are the same, and at a premium if C is greater than F. The divided rate, or bond rate, is the interest rate named in the bond. …

Some Applications Of The Principles Of Isomorphism And Variation To The Teaching Of Geometry, Ralph Mock
Some Applications Of The Principles Of Isomorphism And Variation To The Teaching Of Geometry, Ralph Mock
Mathematics & Statistics ETDs
In summary, it should be stressed that the numerous examples of this paper are important only in so much as they illustrate the use of the devices and concepts emphasized in the study. It is our premise that plane geometry, as usually taught, does not possess the value which it might have. Certain changes in content as well as in presentation would materially improve the course. This study, then, presents suggestions for improving the ordinary course in two directions. First, by presenting logical propositions from the students' experiences which are partially isomorphic to the theorems of plane geometry, it is …
The Efficiency Of Approximation Formulae For Determining The Rate Of Interest In Amortization Schedules, Wade Ellis
The Efficiency Of Approximation Formulae For Determining The Rate Of Interest In Amortization Schedules, Wade Ellis
Mathematics & Statistics ETDs
The problem of this study is to determine the relative efficiency of the more important formulae for approximating the rate of interest involved in an amortization plan when the amount of the debt, the amount of the periodic payment, and the number of periods are known. By efficiency this meant the degree of accuracy obtainable, and the time required for solution.

A Method Of Changing Certain Infinite Series To New But Equivalent Series, Moneta Gunilla Johnson
A Method Of Changing Certain Infinite Series To New But Equivalent Series, Moneta Gunilla Johnson
Mathematics & Statistics ETDs
The purpose of this investigation is to prove that the sum of a series of variable terms of a certain type is equal to a constant plus the sum of another series of variable terms. As a result of this proof it may be hoped that certain series, which so far have not been summed, may be shown equal to a constant plus another series for which the sum is known.
