Hydrothermal Alteration Of Ash-Flow Tuffs In The Indian Peak District Of Southwestern Utah, Michael Allan Tolley

Masters Theses

"Careful petrographic study of the ash-flow tuffs in the Indian Peak District of southwestern Utah reveals hydrothermal alteration around the fluorite veins. The alteration minerals themselves and the intensity of alteration vary with distance from the veins. Primary plagioclase has altered to secondary feldspar, calcite, sericite, and traces of epidote and zoisite. Hornblende and biotite have altered to chlorite, calcite, and secondary iron oxide, and traces of epidote and zoisite. Diopside has changed to calcite and secondary iron oxide. An overall picture of the mining district shows that certain minerals increase and others decrease as one nears the veins. Hydrothermal …

The purposes are to obtain the optimum values of …

Distribution, Petrology, And Environment Of The St. Louis-Ste. Genevieve Transition Zone In Missouri, Donald Howerton Fielding

Masters Theses

"In eastern Missouri, southeastern Iowa, and western Illinois - a transition zone, a body of rock consisting of several lithosomes which has a geographic extent measured in scores to hundreds of miles and which lies between a single overlying formation and a single underlying formation and which has lithologic and/or paleontologic properties common to both the overlying and the underlying formations, was found to exist between the St. Louis and the Ste. Genevieve formations. This transition zone is called the St. Louis-Ste. Genevieve Transition Zone, and is shown to possibly be due to continuous deposition between these two times and …

A Comparison Of Computer Codes For Fast Neutron Dosimetry By The Foil Technique, Jau Wen Chen

Masters Theses

"A comparison of the major codes currently used for fast neutron dosimetry based on the foil technique has been made. These codes are SAND II, SPECTRA and RDMM. The comparison is based upon the deviation of calculated from-measured activities, the input data decks, the obtained information, and the computer time required. Four sets of data were used to be compared upon the above four viewpoints, the conclusion reached is that the SPECTRA computer code is the most satisfactory for the UMR Reactor fast neutron spectrum"--Abstract, page ii.

A Driver-Assisting Control System, Roger Allen Hayes

Masters Theses

"The material presented here explains the electronics of a magnetic guidance control system. The system is based on magnets embedded in the center of the roadway. If a vehicle passes near a magnet, fluxgate magnetometers sense the presence of the magnets and guidance pulses are developed and processed. The end result is a visual output which indicates the direction the driver must steer the vehicle for proper positioning on the roadway. The paper presents a solution to the detection problem caused by the sensor output being a function of the earth's field as well as the field of the guidance …

Stability And Synthesis Of Transfer Functions Rational In W = E To The Power Of The Square Root Of T (S² + Bs + C) And Omega = The Square Root Of T (S² + Bs + C), James Fred Archer

Masters Theses

"The bounded input-bounded output stability is investigated for networks containing uniformly distributed LRGC, LRC, GRC and G(ω)RC elements. The region of stability in the W plane (W = e to the power of the square root of (s² + bs + c), Θ plane (Θ = the square root of (s² + bs + c), and S plane (S = s²+bs+c) is found in each case so that if the poles of a transfer function rational in W, Θ or S lie within this region the system is stable. After obtaining a desired transfer function rational in W = e …

Design And Preliminary Testing Of A Thermomechanical Rock Fragmentation Apparatus, Gary Earl Fenton

Masters Theses

"The design characteristics of equipment to thermally weaken and mechanically fragment hard rock were developed and the apparatus constructed. An initial investigation of thermo-mechanical fragmentation was conducted on Missouri red granite. The particles from the fragmentation tests were sized and this analysis was used in the Rittinger theory to calculate surface area breakage energy. It was found that the application of thermal energy could reduce the surface area breakage energy per unit volume of material removed by as much as 41 percent. The use of kerfs in the rock increased the amount of material removed and permitted larger particles to …

A Study Of The Dislocation Instability And Reverse Martensitic Transformation In Fe-Ni System, Chung Lim

Masters Theses

"Since the martensitic reaction is a strain transformation, the transformation of the lattice structure can be induced by an external stresses. This also means that the macroscopic total elastic constant should decrease as the temperature is lowered to M_s on cooling. For the reverse transformation an anomalous decrease of the elastic constant is to be expected as the temperature increases to A_s on heating. In this experiment measurements of the velocity change of an ultrasonic wave in Fe-Ni alloys were carried out for the reverse martensitic transformation. The deviation from the linear relationship of the velocity change as …

The Pm3m-Fm3m Transformation And Phase Equilibrium In Solid Solutions Of Csc1 With Kc1, Rbc1, And Csbr, John David Weyand

Masters Theses

"Thermal expansion and the Pm3m t Fm3m transition of cesium chloride have been studied with high temperature diffractometry, differential thermal analysis, and heating and quenching techniques. The onset temperature of the transition in pure CsCl, on heating, is 471ºC. There are no observable premonitory effects below the transition temperature and no apparent structural relationships between the polymorphs is apparent. Both phases coexist over a 20º to 50ºC temperature range and equilibrium thermal hysteresis occurs on heating and cooling. Hysteresis behavior is explained by addition of strain energy parameters to the free energy function. Initiation of the Pm3m t Fm3m transformation …

Numerical Solutions Of The Torsional Oscillations Of A Shaft-Flywheel System, Mahendrakumar Ramkrishna Patel

Masters Theses

"The application of the finite-difference technique, the Fourier transform, and the Laplace transform for the solution of a system governed by the one-dimensional wave equation is examined. A specific example consisting of a continuous shaft-flywheel system acted upon by an exciting torque applied at a specific section of the shaft is studied. The exact solution to this example is obtained using the classical method of superposition of modes, and is used as a reference to evaluate the accuracy (in terms of the rms error) and relative efficiency (based on computer time) of three approximate solution methods. A sinusoidal excitation was …

Electric Field Strength Dependency Of The Rate Of Radiation Induced Degradation In Silicon Planar Devices, Cyrus Hoshang Irani

Masters Theses

"The investigation of electric field strength dependence of the rate of damage introduction, caused by gamma and neutron irradiations in matched is reported. Groups of devices (with varying biases applied to the emitter-base and collector-base junctions to allow study of the electric field strength dependence) were exposed to ionizing gamma radiation from a Co-60 source. Similar experiments were conducted to study the field strength dependence of the rate of space-charge volume damage introduction, caused by fast neutrons (E> l0keV, fission source). The experimental results indicate that the rate of surface degradation, as reflected by the increase of the normalized surface …
