Effect Of Hydrostatic Pressure On Anelastic Stress Relaxation In A Mixed-Alkali Silicate Glass, Young-Gil (Gilbert Y.) Kim

Masters Theses

"The effect of hydrostatic pressure on the anelastic stress relaxation of a mixed-alkali silicate glass (0.05 Na₂O, 0.95 K₂O, 3 SiO₂) was studied at 75°C between ambient pressure and 6 kbar. The activation volume of diffusion was found to be - 4.2 cm³/mole. It is proposed that a reequilibration of the defect population at pressure gives rise to the negative activation volume of diffusion"--Abstract, page ii.

The Use Of Turbulence Energy Equation In Boundary Layer Study, Ro-Chi Tai

Masters Theses

"A turbulent boundary layer problem has been studied analytically and compared with an available experiment in the literature. Correlations of the experimental data were made to investigate the validity of the commonly used empirical relations on turbulent shear stresses. It was found that the model which related the local turbulent shear stress linearly with the local turbulent kinetic energy, as used by Bradshow et. al., appeared to be most reasonable. combining this model with the expression of turbulent viscosity given by Boussinesq, it was then possible to introduce the turbulence-energy equation in addition to the governing equations of continuity and …

Computer-Aided Design Of Lossless Non-Uniform Transmission Lines, Larry Lee Wesner

Masters Theses

"A numerical iterative design technique is presented for the synthesis of lossless non-uniform transmission lines. A variational approach is used to minimize an error functional to which the system and boundary equality constraints have been adjoined by Lagrangian multipliers. The resultant network optimization conditions lead to an iterative scheme requiring analysis of the non-uniform line, analysis of an adjoint system and calculation of the error gradient in parameter space. A steepest descent procedure is used to optimize parameter values. Finite difference equations are used to provide an approximation model for implementation on the digital computer. A design example and a …

The Design Of Three-Port Strip Line Circulator, Jeng Seng Chang

Masters Theses

"This dissertation is concerned with the analysis and design of the radius of ferrite disk of strip line circulator using a generalized analytical field expression. The first part consists of an analysis of the field in the ferrite disk with the TEM wave incident normally on the air-ferrite boundary. It is approximated by taking the boundary condition at the incident and outlet points, so that analytical expressions for the electric and magnetic fields can be obtained. The next part consists of an approximate method to determine the radius of the ferrite disk based on the result obtained in the first …

Film Boiling From Inclined Flat Surfaces, Charles Ernest Price

Masters Theses

"The object of this investigation was to determine the effect of inclination on the heat transfer for saturated film pool boiling from a flat plate heater. Nitrogen at atmospheric pressure was used as the test fluid. The test plate was oriented at various angles from the horizontal position and the convective film coefficient was determined for each angle. Tests were conducted for heater angles of 0°, 30°, 60°, and 90°. The heater strip was placed in a container of the liquid and was heated electrically. Heat transfer results were obtained for plate temperatures ranging from 100 to 800°F. As the …

Fast Neutron Effects On Transistor Scattering Parameters, David Leslie Gray

Masters Theses

"It has not been possible in the past to characterize a transistor or other semiconductor device with regard to its performance in a fast neutron (E>10keV) environment when the device is operated at high (>100 MHz) frequencies. Using the scattering (s-) parameter concept, which regards a device as a two-port "black box", a full characterization of the trends in the neutron bombarded high-frequency performance of a typical transistor can be made. Scattering parameters are not only an accurate means of describing the high-frequency performance of any device, but are now reasonably easily measured with the advent on the …

The Effect Of Aging On The Exfoliation Corrosion Characteristics Of 7178 Aluminum Alloy, J. James Slavick

Masters Theses

"The objective of this investigation was twofold: 1) to determine the effect of the quench-to-artificial aging delay period on the exfoliation corrosion of 7178 aluminum alloy subsequently aged at 250F for 24 hours and 2) to determine the effect of an initial aging treatment at 212F on the tensile properties and exfoliation of 7178 aluminum subsequently aged at 250F. Testing was conducted on 0.125 inch thick sheet. Quench-to-aging delay periods of 0 to 28 days, and initial artificial aging treatments at 212F for 24 and 48 hours were investigated. In addition, the effect of overaging T6 material at 320F for …

Tunnel Diode Models For Electronic Circuit Analysis Program (Ecap), Carmon Dale Thiems

Masters Theses

"In this paper ECAP models for the tunnel diode are presented. Results showing the model, the current-voltage charateristics [sic] are discussed. Operation in typical circuits is presented. A summary of the current state of the art in modeling appears in Appendix I. Since ECAP is only structured to accept piecewise-linear models of these devices, that type of model is presented here. All of the models are developed to approximate the typical tunnel diode current-voltage characteristic"--Introduction, page 1.

The Effect Of Small Additions Of Niobium Upon The Corrosion Rates And Electrochemical Potentials Of Iron In Hcl, Hf, And H₂So₄, Richard Lee Jones

Masters Theses

"The valence of niobium ions going into solution was determined by dissolving the metal in hot HF and measuring the volume of hydrogen evolved. The corrosion rates of Nb, NbH_x, Fe and Fe - Nb alloys were determined in various concentrations of NCl, H₂SO₄ and HF. The Fe and Fe - Nb alloy samples were made by using powder metallurgy techniques. It was found that a metal skin was produced on the surface of iron corrosion samples if the carbon content of the surface layer was lower than that of the core of the sample. The lower carbon …

The Incorporation Of Oxygen-18 Into Oxindole Acid By Cells Of Hygrophorous Conicus, William Green Allen

Masters Theses

"To understand the mechanism of a biological oxidation in which oxygen is incorporated into a substrate, it is necessary to determine the origin of the incorporated oxygen. The objective of this investigation was to determine the origin of the oxygen atom incorporated into indoleacetic acid (IAA) by the IAA oxidase of Hygrophorous conicus through the use of oxygen-18. To determine the source of the oxygen atom incorporated into IAA it is necessary to incubate H. conicus cells with tryptamine or IAA in the presence of ¹⁸O₂ and H₂¹⁶O in one case and ¹⁶O₂ and H₂¹⁸O in another. An examination of …

The Influence Of Several Factors On The Rate Of Secondary Compression Of Soil, William Joel Green

Masters Theses

"This research program has been undertaken to study the influence of load increment ratio, temperature, and sample thickness on Cα (rate of secondary consolidation) for a high organic content and low organic content soil. Consolidation equipment was designed to produce constant temperatures both above and below ambient, and to accommodate both 3/4 and 1 1/2 inch thick samples. Samples were molded into oedometer rings at the liquid limit. It was found that Cα was independent of the sample thickness and load increment ratio for both the high organic and low organic soils. The influence of temperature on Cα was found …

The Effects Of Ego-Involvement And Fear Appeals Upon Task Performance, Stephen Steinmetz

Masters Theses

Researchers and scholars in the fear appeal area have been unable to determine what factor or factors make fear appeals effective. Two studies, Hewgill and Miller (1965) and Powell (1965), suggest that the personal involvement of the audience with who or what is threatened is the factor which causes fear appeals to be effective. If ego-involvement is the personal involvement factor indicated by these studies, then it would appear to be the key to fear appeal effectiveness. Therefore, the present investigation was designed to experimentally compare the effects of ego-involvement and fear appeals upon task performance.

Experimental Determination Of Dynamic Properties Of Aluminum Including Poisson's Ratio, Terry Lee Holman

Masters Theses

"Two rods of 7075-T651 aluminum are longitudinally impacted to investigate the material's dynamic properties. The test rod, initially at rest, is instrumented with strain gages to record the strain-time history after the impact rod, accelerated to uniform velocity by an air gun launcher, strikes the test rod. A camera records the strain-time pattern displayed on an oscilloscope. The experiment indicates a consistent rise time of approximately 9 µsec. Simple one-dimensional theory correlates well with the experimental data. Compensation is included for the transverse sensitivity of the gages used. The dynamic values for both the modulus of elasticity and Poisson's ratio …
