Characterization Of Two Mexican Raw Dolomites For Refractory Brick Production, Rodolfo Trevino Cantu

Masters Theses

"Two Mexican dolomites were characterized in order to discover their suitability for production of refractory brick.

The results were compared with other dolomites from American Companies. Some samples were burned in a gas fired Laboratory Furnace and others were obtained in the burned state after processing in Industrial Rotary Kilns.

The characterization procedures included X-Ray Diffraction, Scanning Auger Microprobe, DTA and TGA techniques, Chemical Analysis and Bulk Density measurements.

The procedure to control the quality of the dead-burned dolomite at the industrial level was established taking as the main criteria, bulk density, hydration susceptibility, and impurity levels"--Abstract, page ii.

The Development Of A Selection Model For Coal Conversion Processes., Karen Aldridge Dollar

Masters Theses

"Present research endeavors involving coal conversion technology have encompassed comparisons of the processes on the basis of economics or efficiency. These comparisons lack completeness because many intangible factors pertinent to the evaluations of the processes have been ignored.

A model has been developed to aid in the selection of the optimum coal conversion process for a given situation. The model includes a method for the evaluation of quantifiable factors which affect the decision-making procedure, and also includes methods by which the non-quantifiable factors which are important to the situation may be evaluated. This is a more complete form of decision-making …

The Relation Between A Teacher Evaluation Checklist And Actual Student Course Gains, Thomas Michael Ozee

Masters Theses

The relationship between student gain, as measured by pre and post achievement test measures, and a teacher evaluation checklist, the Student Evaluation of College Teaching Behaviors Instrument (SECTB), was examined in an attempt to validate the eight factors in the SECTB. Sixty seven students in three sections of introductory psychology were measured on both instruments. Results of this study do not support a relationship between student gain and the SECTB. The only significant correlate of gain was a factor measuring nature of presentation (r = -.468) and this correlation was found in only one section. In this section there was …

The Design Of A Hydraulic Jet Coal Cutting Head., Rodney Steven Eck

Masters Theses

"The use of high-pressure water as a tool for cutting coal is discussed. A proposed longwall coal mining machine utilizing oscillating water jets to cut coal is presented. Apparatus for experimentation using high pressure water involving single and dual oscillating jets was designed, constructed, and tested. The design of the cutting head for the proposed mining machine is considered"-- Abstract, p. ii

Electroless And Chemical Metal Deposition On Human Tooth Enamel., Richard Doyle Christie

Masters Theses

"Initial investigations have confirmed the feasibility of depositing an adherent metal film onto tooth enamel. Such films might be used as pit and fissure sealants in preventive dentistry, with denture or orthodontic work, as an intermediate substrate with various organic or inorganic restorative materials, or other such areas. The process employs chemical solutions containing ions of the metal to be deposited and suitable reducing agent solutions.

To date, metallic copper and silver films have been plated onto teeth in vitro. The deposits are quite adherent and appear to exhibit the conductivity, crystal structure, luster, hardness, and other chemical and physical …

A Method For Verifying The Kalman Conjecture., Charles Edward Connelly

Masters Theses

"The Kalman and Aizerman conjectures are of value because, if true, they allow the replacement of a nonlinear stability problem by an equivalent linear stability problem. However, the conjectures are not true in general. This thesis presents a method for verifying the Kalman conjecture. A theorem is also presented which extends the usefulness of the method and allows several very general results to be obtained. The method is based on an off-axis circle criterion of Cho and Narendra and a consideration of the curvature of the Nyquist locus of the transfer f unction. A table is included which summarizes the …

Performance Evaluation Of Linear Systems Using The Fast Fourier Transform., Larry Leonard Lamano

Masters Theses

"In order for a computer simulation of a communication system to yield useful and meaningful results, a method for determining system performance is often essential. The computer postprocessor, described in this thesis, allows accurate determination of the mean-square-error induced by the system being simulated and the noise power at any point in the system.

Measurements of the mean-square-error induced by a system due to amplitude distortion, phase distortion, and amplitude and phase distortion, along with measurements of the power in a Gaussian noise waveform are performed. The values obtained using simulation are compared to the corresponding theoretical values in order …

A Study Of The Effects Of Numerical Error Propagated Through Several Independent Stages: An Electron Optics Simulation., William Donald Webster

Masters Theses

"Presented is a study, combining numerical methods in a series of stages whereby each stage provides input data to its successor. A model problem from electron optics ii is studied in which a potential field is computed, gradient vectors calculated, and trajectory equations solved. Error effects in each stage is assessed for its influence on the final results of the numerical process mimicking the model problem. Error analysis is given in Appendix A. Finally, the superiority of Spline approximations for estimating derivatives is demonstrated"-- Abstract, p. ii

Reflected Surface Waves From A Vertical Discontinuity., Jesus Manuel Aboud

Masters Theses

"Surface waves generated in the field by small explosions were observed along lines parallel and perpendicular to a vertical discontinuity in a surface layer. Three types of wave particle motion were observed in waves incident on the discontinuity: retrograde, progressive, and shear (SH). Waves of the last two types were intense enough to observe a reflection, permitting calculation of reflection coefficients. The results demonstrate the feasibility of using reflection measurements to locate a discontinuity such as a fault zone"-- Abstract, p. ii

Phase Equilibria Near The Solidus Temperature For Iron-Rich Fe-Cu-C Alloys., Kenneth L. Metz Jr.

Masters Theses

"The effect of copper on the solidification temperature of graphite-saturated iron-rich alloys was determined with the use of cooling curves. The ternary invariant temperature for the alloy was found to be 1172°c with the use of heating curves. At 1172°c, graphite, austenite, an iron rich liquid, and a copper-rich liquid are in equilibrium. The composition of the metallic phases was determined by weight gain, chemical analysis, and the electron microprobe. In addition, the composition of the iron-rich liquid was calculated from thermodynamic data. Isothermal sections of the iron-rich corner of the system were constructed for several temperatures in the range …
