Determining Stability Of Nonlinear Control Systems Via Lyapunov's Method., John Joseph Komo

Masters Theses

"The problem undertaken in this thesis is to present Lyapunov's method of stability as i t applies to control systems and to use it in the stability analysis of nonlinear control systems. The variable gradient method of generating Lyapunov functions is presented since this seems the best general procedure for obtaining Lyapunov functions. Also, the integration of matrices method is presented as a comparison. ii

Procedures for the use of the variable gradient method and the integration of matrices method are written and several examples are used to illustrate these procedures.

It is concluded that Lyapunov's method is very definitely …

Masters Theses

"The development of nuclear fission reactors to convert nuclear energy into electrical energy for use in industry, public utilities, military applications, and space exploration has resulted in ever increasing quantities of radioactive waste solutions. Significant reductions in nuclear fuel costs will be obtained when economical processes have been developed for recovery and purification of valuable fission products which are contained in radioactive waste solutions and are in demand for many research applications.

The United States Atomic Energy Commission has supported exhaustive studies to recover fission products by processes involving the more common unit operations such as extraction, distillation, crystallization, and …

The Measurement Of The Life-Time Of The 62P3/2 State Of Thallium, Danny Hale Sokolowski

Masters Theses

The measurement of the lifetime of the metastable 6²P_3/2 state of thallium is discussed. Time-sampling equipment techniques and instantaneous methods of display on an oscilloscope for measuring the lifetime are explained. The lifetime is measured as a function of mercury vapor pressure. The decay of the 5350 A thallium line is also measured to give an indication of the effect of the imprisonment of the 3776 A resonance line. This decay of the 5350 A line is also in a mercury atmosphere"--Abstract, page ii.

Analysis Of Problems In The Performance Of A Natural Gas Storage Reservoir., Gerald Eugene Henderson

Masters Theses

"A digital computer technique is presented for predicting two parameters of underground natural gas storage reservoir performance: (1) the prediction of reservoir pressures and volumes, and (2) the prediction of optimum flow rate and pressure drawdown for a single well in accordance with the theory of water coning.

The outlined procedure for predicting gas storage reservoir pressures and volumes was not effective for the field studies, although certain conclusions have been drawn which should be beneficial in further studies.

The procedure for predicting optimum gas flow rate and pressure drawdown from a well without production of bottom water involved first …

The Justification For And Design Of A Lunar Radio Observatory., Thomas Van Doren

Masters Theses

"The purpose of a radio telescope is to record information concerning the strength, spectrum, polarization, and direction of arrival of extraterrestrial electromagnetic radiation at radio frequencies. Earthly based radio observatories are hampered in their attempt to achieve this purpose by atmospheric absorption and reflection of the radiation. A lunar based system would not have this problem because the Moon possesses practically no atmosphere. However, other environmental conditions, such as micrometeorites, high frequency radiation, and extreme temperature variations, must be overcome. This thesis justifies the need for a lunar radio observatory and also describes a particular radio telescope system which should …

The Electrochemical Degradation Of Alkyl Benzene Sulfonate., Melvin David Rickard

Masters Theses

"The ever increasing use of nonbiodegradable synthetic detergents, mainly the alkyl benzene sulfonates, has created difficulties in water and wastewater treatment, and in stream pollution. Although considerable attention has been given to this problem, no solution has been developed which can be effectively employed in the abatement of detergent pollution.

The purpose of this investigation was to determine the feasibility of the use of direct current electrochemical degradation in the removal of alkyl benzene sulfonates (ABS) from water. The rate and degree of completion of the electrochemical reactions were determined, and the nature of the end products formed was investigated. …

Parameters In Ablation Heat Sheilds, Franklin Chang Liang Lin

Masters Theses

"The desired result of this paper is a method of determining temperature distribution and burn off rate in a semi-infinite rod or shield subjected to a large heat flux. The possible methods of determination were investigated, and it was felt that an analytical approach turned out to be the most feasible.

The analytical analysis employed involves the use of the Fourier's general equation for one dimensional heat flow. Transformations from stationary to moving coordinates reduces the problem from unsteady state to steady state boundary conditions. The resulting equations can be applicable to the extent for the heat flow problems involving …

The Design, Construction, And Calibration Of An Apparatus To Determine The Thermal Conductivity Of Solids, Alan Edward Stephenson

The apparatus used in this investigation is a modification of the guarded hot plate method used by the American Society for Testing Materials. Operation of the device is given in a step by step procedure both as a guide for others and also to show how it was operated during calibration of the apparatus. Data obtained in the calibration is given in tabular and graphical form …

A Study Of The Angular Velocity In A Liquid Induced By A Vortex In An Emptying Container, James Paul Hartman

Masters Theses

"Previously a limited amount of investigation has been done to describe the rotational motion of fluid in a draining tank. To date tank design has been based on trial and error, since the physical mechanisms of actual draining have not been recognized. This investigation has been made to develop a technique for the measurement of the motion of the fluid during the draining process and to present the results of the observed surface velocity of the liquid as a function of depth of fluid and its distance from the center of the vortex core. Many previous investigators of vortex behavior …

A Graphical Solution Method For The Tchebychev Elliptic Function Filter, Gene S. Luckfield

Masters Theses

"This thesis is concerned with the design of the Tchebychev elliptic function filter. The Darlington synthesis procedure is discussed and salient points from Darlington's paper needed for the design of this filter are presented.

It is shown that the design of the Tchebychev elliptic function filter requires a knowledge of the elliptic functions, particularly the elliptic sine. Since the use of these functions is not common, a brief review of their properties is presented.

Using the elliptic functions, a development of the equations describing the behavior of the Tchebychev elliptic function filter is given for the case of a normalized …

A Rc Active Delay Time Network., Robert Sun-Wu Han

Masters Theses

"This thesis presents a method for performing an approximate synthesis of a variable delay time network by using RC elements and active analog computer circuits. The delay networks discussed here can provide delay times which range from zero to 96 milliseconds for inputs with frequencies which range between zero 2nd 5 cycles per second.

Basically, the procedure involves approximating the delay time transfer function, e^-jwTd , by the ratio of two polynomials each of which is represented by a finite series of terms. The ratio is then shown to be easily synthesized by RC elements and analog computer circuits. …

These have been intruded in the northern part of the area by a batholithic body of granitic composition, a granitic stock, a pegmatitic granite, a granitic sill-like body and different types of pegmatite dikes and sills. The youngest intrusions are a series of northeast trending basic dikes and sills. A major easterly trending transverse fault and a series …

The Effect Of Food And Drug Laws On Producers Of Paper And Paperboard Used For The Packaging Of Food, Charles W. Walton

Masters Theses

In 1958 the Food Additives Amendment to the Federal Food, Drug and Cosmetic Act was adopted causing a great deal of concern on the part of producers of packaging material. Any ingredient of the package that might migrate or transfer to food contained in the package became, by definition, a food additive subject to regulation and prior approval of the Food and Drug Administration.

Other acts and regulations have been adopted since 1958 indicative of increasing concern by the Federal Government for consumer welfare. This activity can be expected to have far reaching effects on manufacturers who must depart from …

The Congressional Phase Of The Military Budget, 1961: A Study In Civil Military Relations, Leland E. Hall

Masters Theses

Introduction

Civilian control of the military in the United States is widely conceived to be Congressional control. The ultimate goal of Congressional procedures is believed to be the "effective Congressional--and civilian--control of the military establishment."¹ It is questionable, however, if the United States Constitution intends Congress to be the instrument that exercises civilian control of the military.

An Investigation Into The Possible Relationship Between Reading Ability And Functional Articulatory Defective Speech, Joan Elizabeth Weir

Masters Theses

Introduction

The purpose of this study is to investigate the relationship between reading disability and defective articulation. An attempt has been made to determine whether or not children with functionally defective articulation have difficulty in reading.

It is conceivable that a deficiency in one or several areas of language development might impede or retard a child's academic achievement and might interfere with his emotional adjustment. This study was, therefore, undertaken, first to determine whether or not there is a difference in the reading ability of speech defective children as determined by valid and reliable measures, and the reading ability of …

Specific Language Disability As Related To Clinical Failure In Public School Speech Therapy, G. Lorraine Hansen

Masters Theses

Chapter I

Background of the Problem

Introduction. The term language as used in this thesis refers to the complex symbolic processes of speaking, reading, and writing. Speech is the primary process of language. Reading and writing are secondary processes formed by written symbols which reflect the primary symbols of speech. Due to the integral relationship of these elements, a facility or disability in one might affect the others. If this is true, then it might also be possible that one currently existing factor could affect the entire area of language including any, or all, of the interrelated processes. It is …

An Investigation Of The Genetic Basis Of Alcoholism, Daniel F. Malamud

Masters Theses

Introduction

Alcoholism: The Disease

"Alcoholism is a chronic disease manifested by repeated implicative drinking so as to cause injury to the drinker's health or to his social or economic functioning" (53). Such a definition of alcoholism points to the disease concept which went unrecognized until recent years. In addition to its medical implications, alcoholism has been the subject of considerable writing and research by academicians in such diverse fields as sociology, psychology, physiology, psychiatry, theology, and law.

At the outset it should be noted that the writer is aware of the arguments and opinions expressed by the advocates of the …

Comparison Of Alcohol Offenses Of College Students With Those Of Persons In A Similar Age Group Who Have Not Had College Experience, Cornelis Laban

Masters Theses

Introduction

The purpose of the study was to·make· a comparison of the drunk driving behavior of college students with that· of those persons in a similar age group who have not had college experience. There is very little published information about the statutes governing "driving under the influence of liquor" (D.U.I.L.). The educable nature of persons involved in such offenses 8 and the probable anti-social and sociopathic behavior in individuals leading up to the offenses, also need thorough investigation. Very pertinent also is the question whether or not there is a biological basis for this particular behavior; an understanding of …

A Study Of Aging In An Old Order Amish Mennonite Community, Louise Chahbazi

Masters Theses

Introduction

The Old Order Amish Mennonites, undoubtedly the plainest of the "plain people," have a high regard for the beliefs and customs of their forebears. Their forefathers had no telephones, automobiles, electric lights, radios, or church buildings, so the Amish of today work the land with horses, travel in buggies, burn gas lights, gather in homes for worship services, and wear styles of dress which were common in seventeenth and eighteenth century Europe.

Estimates made on the basis of recorded church membership in the Mennonite Yearbook place the Amish population of the United States at approximately 57,000. Their high birth …
