Rapid Calculation Of Electron Scattering Factors, Jerry Peacher, John G. Wills

Physics Faculty Research & Creative Works

The phase amplitude method is used to reduce the radial Schrödinger equation to two separate differential equations, one for the phase and one for the amplitude. These functions are both smooth as opposed to the rapidly oscillating solution of the radial Schrödinger equation for electron energies in the kilovolt range. The partial-wave phase shifts were obtained rapidly by integrating the differential equations for the phase and amplitude numerically. Hartree-Fock and Thomas-Fermi-Dirac fields were used in the calculation. Results for argon and uranium are given in order to compare with previous results. It was found that the WKBJ approximation to the …

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 Study Of An Electric Method To Excite And Detect Acoustic Waves In Solids, John H. Stevens

Masters Theses

"This experiment has demonstrated that it is possible to generate pulses of acoustic waves in an aluminum single crystal by the direct use of the tensile stress associated with an electric field at the surface of a conductor, and it is possible to detect these waves with a biased, capacitive pickup transducer"--Abstract, page ii.

The Realization And Application Of Parallel Linear Feedback Shift Registers, Ross K. Heitzmann

Masters Theses

"Two methods for serial-to-parallel transformation of linear feedback shift registers are briefly discussed. A third method for transformation is rigorously developed using a next-state and output equation representation of the linear feedback shift register. An algorithm is developed for simplifying the parallel machine resulting from serial-to-parallel transformation, where simplification is defined as reduction in the required number of modulo 2 adders. A computer program incorporating serial-to-parallel transformation and the simplification algorithm is provided "--Abstract, page ii.

Infrared Spectra And Magnetic Properties Of Fluorine Substituted Copper (Ii) Alkanoates, Jose G. Rodriguez

Masters Theses

"The purpose of this study was to prepare some selected copper(II) fluorcalkanoates, investigate their magnetic susceptibilities, study the infrared spectra of these salts and compare these properties to those of the unfluorinated copper(II) alkanoates….

The experimental data obtained indicate that the copper(II) trifluoroacetate, perfluoropropanoate and perfluorosuccinate does not form a binuclear cage structure. Copper(II) 3-(trifluoromethyl) butanoate with a magnetic moment of 1.4 should possess a binuclear case structure similar to copper( II) acetate monohydrate. The structure for copper( II) perfluoroglutarate monohydrate with a magnetic moment of 1.63 B.M. should have a structure somewhere between the two aforementioned structures"--Abstract, page ii.

Magnetic Properties Of The Bifeo₃-Pbtio₃-Pbzro₃ Ternary System, James Ivan Latham

Doctoral Dissertations

"The magnetic susceptibility and spontaneous magnetic moment of the perovskitic, polycrystalline solid solutions of BiFeO₃ with PbTiO₃, PbZrO₃, and [50PbZrO₃·50PbTiO₃] were determined using the Faraday method. Pure BiFeO₃ has a G-type antiferromagnetic structure. Although the perovskite BiFeO₃ exhibits a sharp peak in the susceptibility at the Néel temperature, it does not possess a spontaneous magnetic moment. The solid solutions investigated possessed a spontaneous magnetic moment throughout the multiple cell rhombohedral region of the BiFeO₃-PbTiO₃-PbZrO₃ ternary phase diagram, which extends from pure BiFeO₃ to …

A Multiple-Input Chemical 'Memistor' For Adaptive Circuits, Richard Franklin Crall

Masters Theses

"A modification of Widrow’s "memistor" is made in a form suitable for extension to multiple-input devices. This modified form is extensively investigated using analog field maps, and through experimental testing. The multiple-input device presented exhibits good adaptive characteristics and reduces the number of interconnections required in the external circuitry"--Abstract, page ii.

Continuous Countercurrent Evaporation Through Porous Water-Repellent Membrane With Pressure Above Atmospheric, Yung C. Hsu

Masters Theses

"An experimental method for measuring mass transfer rates at pressures above atmospheric has been developed for the case of continuous countercurrent evaporation through porous water-repellent membranes. The final developed equipment is suitable for operation under pressures up to 50 psig and at temperatures near the boiling point of 7% salt water when high flow rates are reached. Rates of evaporation of water through the membrane were measured, and the data and results were used to examine the effects of operating conditions on the over-all mass transfer resistance. Least squares equations for fitting the data were also obtained. Over-all mass transfer …

Radial Pressure Gradient In Turbulent Pipe Flow, Gary Kent Patterson, Walter J. Ewbank, Virgil A. Sandborn

Chemical and Biochemical Engineering Faculty Research & Creative Works

Measurements made with a Prandtl static pressure probe have demonstrated that a radial pressure gradient does exist in turbulent pipe flow with approximately the magnitude predicted by Sandborn from hot-wire anemometry measurements.

The Effect Of Concentration On The Viscosities Of Solutions Of Linear Flexible High Polymers, Lung Yu Chou, Jacques L. Zakin

Chemical and Biochemical Engineering Faculty Research & Creative Works

Viscosity-concentration results in the moderately concentrated range for four samples of polyisobutylene (molecular weights of 1.3 x 104 to 1.0 x 106) in cyclohexane (concentrations up to 4.7 g./dl.) and in benzene (concentrations up to 7.0 g./dl.) at 24°C. (a theta solvent) showed molecular weight and goodness of solvent dependencies similar to those reported earlier for three other polymers. For polyisobutylene, polystyrene, and a copolymer of styrene and methyl methaerylate in good solvents, viscosity-concentration data plotted as ηsp. C[η] vs. k′[η]C fit a single curve. The linear region of this curve suggests that the Huggins equation is useful to C[η] …

Computer Solutions To Depletion Drive Hydrocarbon Systems, Tu Kao Chen

Masters Theses

"Three computer analyses of oil production by depletion drive have been developed. These analyses, Tarner's method of depletion drive oil production prediction, depletion drive performance productions of Schilthuis, and depletion drive calculations by a finite difference material balance, have been programmed for computers having Fortran IV compilers and a minimum of 40 K bytes of core storage capacity. Modifications have been incorporated in the last two techniques for (a) constant volume injection of produced gas, (b) the presence of a gas cap, (c) gas-cap injection of produced gas volumes, (d) varying water encroachment and production, and/or, (e) varying sweep efficiencies …

Stresses In A Thick Spherical Shell, David Wayne Moore

Masters Theses

"This thesis reports a method to evaluate the stresses in a segment of a thick spherical shell. In the numerical examples loads due to thermal expansion as the shell is constrained at the free edge and a dead load acting vertically downward were considered for a shell assumed pinned but free to rotate and for a shell assumed completely fixed at the edge. A concrete shell was specifically studied but the method would also apply to a shell of any homogeneous, isotropic material"--Abstract, page i.

Some Aspects Of Transient Flow Behavior In Artesian Aquifers And In Hydrocarbon Reservoirs Surrounded By Artesian Aquifers, Alton John Nute

Masters Theses

"An analysis of the principal theories concerning the transient movement of water in artesian aquifers and from artesian aquifers into hydrocarbon reservoirs is presented. Various analytical methods which can be applied to depict the behavior of these two types of aquifer systems are compared.

Most aquifer studies to date have been based upon the Thesis Non-Equilibrium Formula. This equation has been used to calculate the coefficients of storage and transmissibility for aquifers; to evaluate well performance; and to investigate problems concerning recharge, movement, and discharge of aquifer water. However, one problem which still remains is that of accurately predicting the …

The Separation Of Optical Isomers By Gas Chromatography, Donald Ellis Carpenter

Masters Theses

"The purpose of this investigation was to study the separation of optical isomers by gas chromatography. An optically inactive solid support was coated with an optically active substrate. Racemic compounds were used as samples. The optically active packing materials tried were d-tartaric acid, d-diethyl tartrate, sucrose, d-camphoric acid, d-camphor-10-sulfonic acid, α -methyl-D-glucoside and L-(α)-glutamic acid.

Racemic compounds that were tried included 2-butanol, 3-methyl- 2-butanol, 2-methyl-1-butanol, 2-octanol, 2-bromooctane, 2-methoxy-octane, methyl-2-bromobutyrate, and 3-methylhexane.

It was found that racemic compounds could be separated by using an optically active material for packing in the gas chromatographic columns. Racemic 2-butanol, 3-methyl-2-butanol, and 2-methyl-1- butanol were …
