An Investigation Of Consolidation On Compacted Partially Saturated Clarksville Soil, Ma-Tai Matthew Chen

Masters Theses

"The Terzaghi theory of consolidation and the assumption of his theory, pore pressure and effective stress, secondary compression and rheology were all reviewed and discussed. Eight compacted unsaturated samples made from Clarksville silty clay (CL) under different compaction efforts and moisture contents were subjected to consolidation load increments. Each load increment was maintained for 24 hours. An extra compacted sample was loaded for one month to investigate secondary compression.

From e-p curves, five settlement vs. compacted embankment height curves were derived for different compaction effort and moisture contents. These curves may be of practical use, when checked by field measurements …

Kinetics And Mechanisms Of Base-Catalysed Reactions, Rohit Panalal Sheth

Masters Theses

"Base-catalysed reactions normally involve complex series of transformations. their kinetics is usually governed by a variety of equilibria, participating in the overall and concurrent processes as well as by competitive side-reactions that interfere with the normal course of such reactions. Mechanisms which have been proposed, by and large, are primarily based on product, by-product and intermediate analyses together with some scattered kinetic and isotopic evidence. In the cases where kinetic studies have been attempted, highly complex mechanisms have usually been proposed due to the frequent necessity of using heterogeneous media or employing involved mathematical treatments to describe the kinetics of …

Mass Transfer In Droplets With Turbulent Internal Circulation - Mathematical Description, Jayantilal Mohanbhai Patel

Masters Theses

"This investigation was carried out to check the accuracy of the eigenvalues, λ_n, calculated by Wellek and Skelland, using some method other than the Rayleigh-Ritz technique and also, to determine the coefficients, B_n in series solution, which were not calculated before.
The eigenvalues were obtained by trial and error procedure using the standard Runge-Kutta method. The coefficients B_n were obtained by using eigenvalues. By using this information the fractional extraction was calculated as a function of droplet contact time.

The Wellek-Skelland modification was also solved by finite difference technique to compute fraction extracted as a function …

Nucleate Boiling Heat Transfer To Liquid Nitrogen At Atmospheric Pressure, Satish R. Parikh

Masters Theses

"The object of this investigation was to study the effect of micro-roughness, a thin layer of oil, and infra-red radiations on the cylindrical heat transfer surface of copper, in liquid nitrogen and at atmospheric pressure during nucleate boiling. An attempt was made to find any possible effect of orientation of the heat transfer element on nucleate boiling. A number of different runs were taken with different degrees of roughness, and different orientation positions. Nucleate boiling has been found to be nearly independent of the heat transfer surface roughness and of orientation while strongly dependent on the chemical nature of the …

An Ac Method Of Measuring The Conductivity Of Dielectric Liquids., Henry E. Fischer

Masters Theses

"The problem undertaken in this thesis is the presentation of a method of measuring the conductivity of dielectric liquids in which the liquid is used as the parallel tank circuit of a modified Wien-bridge oscillator. The main advantage of this method is that the frequency of the voltage applied to the liquid can be varied by simply varying the oscillator frequency. This allows the selection of a frequency which is best suited to the liquid in regard to polarization and relaxation time.

An oscillator was designed, built and used in the laboratory to measure the conductivity of the dielectric liquids …

Analysis Of Time-Varying Linear Multipole Filters With Sampled Nonstationary Random Inputs, Ming-Chwan Chow

Masters Theses

"In this thesis an analytical method is developed to determine an optimum time-varying linear filter in order to satisfy the following specifications. The filters are of sampled data multipole form with n inputs and m outputs. The signal of each input is a member of a nonstationary random process, and the signal is corrupted by stationary noise.

The statistical optimization theory developed by Wiener is extended to a linear time- varying filter with nonstationary input. Correlation functions are defined for nonstationary ensembles. The mean- square error is calculated in terms of these correlation functions. By minimization of the mean-square error, …

An Application Of The Variable Gradient Method Of Generating Liapunov Functions To Discrete Systems, Henry N. Peterson

Masters Theses

"The variable gradient method of generating Liapunov functions has been used only for continuous systems. This thesis presents an application of the variable gradient method to non-linear sampled data control systems.
Certain modifications to the variable gradient method are developed and several examples are presented which demonstrate the application. An attempt was made to synthesize the control system parameters, but due to the complexity of the ΔV functions, the synthesis in general cannot easily be obtained . To circumvent the problem of determining if the ΔV functions are negative definite, a set of computer programs were written to determine a …

Study Of Heat And Mass Transfer Through Non-Wettable Porous Membrane, Rajender Kumar Rohatgi

Masters Theses

"The object of this investigation was to study the use of non-wettable porous membranes for simultaneous heat transfer and mass transfer of water from a hot salt solution stream to a cold distilled water stream, the streams being in countercurrent flow separated by the membrane. This type of mass transfer was achieved in the experiments, and mass and heat transfer coefficients were measured.

The membranes studied in this work were made of fiberglas treated with Teflon dispersion and aluminum sulphate. The fiberglas membranes yielded desired results. Empirical correlations were proposed which predict values of heat and mass transfer coefficients close …

The Orientation And Mobility Needs Of Blind Youth In A Highly-Impacted Metropolitan Area, Lawrence E. Blaha

Masters Theses

Introduction

Mobility enables man to interact with his surroundings, and to influence his environment as well as to be influenced by it. The need for the blind individual to relate himself to his environment has been the motivation for the development of orientation and mobility instruction.

While orientation and mobility for the blind is a relatively new discipline, the systemic use of basic techniques, i.e. hand-and-arm techniques and the use of long, light, functional cane as a mode of travel, has been validated empirically with more than a thousand blinded adults. These techniques have also been used successfully with blind …

Phase Shift Analysis Of Protons Elastically Scattered By 016 Near EP = 8.3 Mev, Glenn D. Westin

Masters Theses

Chapter I

Introduction

The study of the resonances in the scattering cross section of the p + O¹⁶ reaction can reveal information regarding the energy levels of the compound nucleus F¹⁷. The analysis is simplified because of the zero spin of the O¹⁶ nucleus. Also, the low binding energy of the proton added to O¹⁶ allows examination of the low-lying energy levels in F¹⁷.¹ The reaction has been intensively investigated at the University of Wisconsin in a series of experiments using an electrostatic accelerator as a source of protons.

The Calculation Of The Cross-Section Of The Interaction Between Two Yang-Mills Fields, Richard A. Starr

Masters Theses

The Problem and Its Background

This thesis presents a study of the interaction between two arbitrary fields, named Yang-Mills fields¹ for their originators. The basic equations for the calculations of the Yang-Mills interaction are due to modern quantum field theory and its specific application to quantum electrodynamics.²

Much useful information can be obtained from the formulation of the dynamical equations for a classical system: for example, the classical description of the electromagnetic field, based on Maxwell's equations, leads to wave concepts. Then using this formalism as a starting point, one can proceed to the quantum theory of free …

Study Of The Stereochemistry Of A Carbanion Generated From An Azoacetate, Nguyen Thanh Buu

Masters Theses

Introduction

The reaction of lead tetraacetate with ketohydrazones to form azoacetates has been reported recently by Iffland, Salisbury and Schafer (13) and may be represented by the following equation:

R₂C=N-NH-R' + Pb(0Ac)₄ → R₂C-N=N-R' + Pb(OAc)₂ + HOAc OAc

Of principal interest has been the base-catalyzed decomposition of an azoacetate in a protonic solvent to give a ketone, a hydrocarbon, nitrogen and an acetate salt. The following sequence of steps has been proposed to account for these products (11).

An Investigation Of The Relationships Between Judgements Of Esophageal And Artificial Larynx Speech Made By Sophisticated And Naïve Judges, Gerald Robert Moses

Masters Theses

The Background and Purpose of the Study

Introduction

Laryngectomy, the surgical removal of the larynx, is performed to save life threatened by a carcinomatous condition of the larynx. This surgical procedure is also performed when necessitated by accident, injury or other pathologies of the larynx. (35).

There are living, in the United States, an estimated 15,000 to 20,000 individuals who have undergone surgical removal of the larynx due to the carcinomatous condition of that organ (33). It is probable that the total population of laryngectomized persons would exceed this number if statistical information were available concerning the number of laryngectomies …

An Investigation Of The Maturation Of Articulation Of Elementary School Children, Thomas D. Marshall

Masters Theses

The Background and Purpose of the Study

Introduction

Developmental studies of speech (12, 13, 24) have indicated that the growth of articulation skills in children follows a definite pattern, with the vowels being first mastered, then the consonants, and finally, the consonant blends. Studies generally agree that the normal child acquires essentially adult articulation by eight years of age. It may be expected, then, that in the early elementary grades, immature articulation skills are not unusual in normal children, and that at higher grade levels, immature articulation skills are relatively less common. Mills and Streit (11), in a survey of …

An Investigation Of Adaptation To The Delayed Auditory Feedback Effect By Normal Speakers, Nelson H. Bormann

Masters Theses

Introduction

Research is being conducted in numerous areas of interest in an effort to better understand the functionings of the various speech deviations. One promising area of investigation is studying speech production as an automatic-control system or a servosystem. Interest in studying the theories of servosystems was greatly stimulated by the work of Nobert Wiener, who first formulated and developed the science of cybernetics. An integral aspect of cybernetic theory is the concept of controlling the behavior of a system by monitoring and evaluating the system's own output. Wiener stated that, in its simplest form, "...the feedback principle means that …

Masters Theses

Chapter I

The Problem and Its Background

Introduction

Over the past several decades there has been increasing interest in the occupational choices of men and women, and the interests and attitudes associated with various professional groups. Since occupations are becoming increasingly more specialized, employers and educators have found that those people who perform best in the position of their choice are those who exhibit certain interests and attitudes with regard to their occupation. Colleges emphasize the necessity of counseling in order to enable students to effectively choose general areas of concentration. The fields of study chosen by students are a …

The purpose of this paper is to acquire a better understanding of the relationship between grace and tree will, that is, the paradox between the omnipotence of God and human free will. More specifically speaking, this paper will deal with two historical approaches to the problem, namely, Baneziem and Molinism. At the onset we shall learn something about Domingo Banez, O.P. and Luis de Molina, S.J. who were largely responsible for the systems which bear their names. We shall then learn something or the historical circumstances which produced Banezism and Molinism and also some or the …

Great Britain And The Balkan Crisis Of 1875-1878, Carol Zainfeld Becker

Masters Theses

Introduction

For years Great Britain had followed the time-honored doctrine in foreign affairs of maintaining the balance of power which meant

to resist by diplomacy or arms the growth of any European State at once so formidable and so potentially hostile as to threaten our national liberties, the security of our shores, the safety of our commerce or the integrity of our foreign possessions.

With the defeat of Napoleon in 1815 and the establishment of the Metternichian concept of the concert of Europe, Britain's historic determination to preserve the balance of power gave way to a new attitude in foreign …

An analysis of the relationships between public policy and public opinion is vital to gaining an understanding and appreciation of the political process in the United States. According to democratic theory, citizens are to be free to express their views on issues and policy decisions. In a representative democracy the elected officials are supposed to carry out the wishes of their constituents. This study is directed toward analyzing the relationships between foreign aid policy and public opinion toward ten selected policy changes which have taken place since World War II. It focuses on the formal foreign aid program; and, …

Nuclear Magnetic Relaxation And Diffusion In Paraffin Oil, David E. Parker

Masters Theses

Introduction

Since the introduction of the spin echoes technique by E. L. Hahn¹ many studies have been made in the determination of the spin relaxation T₂, spin-lattice relaxation T₁, and the diffusion rates in gases, liquids^2-5, and solids^6-10. Hahn's methods were later improved by Carr and Purcell¹¹. The Carr-Purcell method serves as the basic technique for this study.

Several studies have been published on the relaxation and diffusion rates in hydrocarbons¹². These studies have shown:

1. The spin relaxation time T₂, is independent of the …

Negligence In The Operation Of Business Aircraft, Daniel J. Garber

Masters Theses

Introduction

Basis for Business Aircraft

The use of airplanes as a production tool for executives and supervisory personnel by business firms in practically all fields of endeavor is ever increasing. This is true even though the airlines have largely substituted pure jet aircraft for piston powered airplanes and turbo-propelled ships on the trunk routes. This makes it more difficult for the business aircraft to save the executives of a company time and money by cutting down transportation waste in obtaining more hours of usefulness from those persons using business aircraft transportation and less expense for employee's hotel, meals and other …

Social Distance Attitudes Of College Students Toward Three Minority Groups, Dennison W. Nichols

Introduction

This study is an endeavor to add to the already existing scientific information in regard to man's social relations with his fellow men. More exactly, the purposes of this research are: (1) to gain a better understanding of prejudice among college students toward both stereotype images and "real" described persons belonging to the Jewish minority, the Negro minority and the homosexual minority, (2) to explore the possibility of their being a relationship between social-distance attitudes of these students toward these minorities and the personal, economic and certain other factors influencing these students, and (3) to consider the significance of …

Helianthus Annuus - The Separation And Identification Of A New Fatty Acid, Donald C. Gruber

Masters Theses

Introduction

The term "fatty acids" was first applied principally to saturated, monobasic carboxylic acids and especially to long chain acids derived from animal and vegetable oils. As time passed and the knowledge of natural fats increased, polyunsaturated, hydroxy, keto and branched chain acids were also found as constituents of these fats and oils and these also came under the heading of fatty acids. Even acids containing alicyclic substituents were found.

More recently the term 11 fatty acid" has been applied to include saturated and unsaturated monobasic carboxylic acids and several other series of substituted acids having carbon skeletons similar to …
