An Analysis Of Conceptual Color Matching, James T. Northrop

Masters Theses

The key pecking responses of six pigeons were reinforced in the presence of a bisected response key when both halves were of equal wavelength; responses to non-matching presentations were not reinforced. Subsequent generalization tests involving novel non-matching stimuli were conducted in extinction. The results indicated the acquisition of a conceptual color matching discrimination; however, post-discrimination training peak shifts may interfere with the demonstration of the concept of color matching.

High Speed Magnetically Supported Vehicles For Reducing Transportation's Degradations Of The Environment, Pravinchandra Shukla

Masters Theses

"The development of new techniques for higher speed transportation is desirable to satisfy the environmental, conservation, and economic requirements of society. Some of the important factors are presented for developing magnetically supported vehicles. A new method for improving the ratio of lift force to drag force is suggested and discussed. An application of the new technique to vehicles that would ride on a carpet of magnetism and would operate with less waste of energy is suggested "--Abstract, page ii.

The Morphology Of The Cellular Precipitation Reaction In A Pb-3.0 Wt% Sn Alloy, Federico Sequeda Osorio

Masters Theses

"The complete development of the cellular precipitation structure at selected grain boundaries in a Pb-3.0 wt% Sn alloy during aging at 34°C and 23°C was investigated by light microscopy. The cellular structure in this alloy consists of lamellae of solute depleted lead solid solution and lamellae of ß tin precipitate. The cellular precipitation reaction begins by local migration of a grain boundary with concomitant grain boundary precipitation of ß tin. The grain boundary bows around the ß tin grain boundary precipitates which then begin to lengthen in the direction of boundary migration thus forming the precipitate lamellae of the cell. …

Computer-Aided Circuit Optimization Including The Adjoint Method Of Calculating Network Sensitivities, John Walter Olson

Masters Theses

"A complete discuss ion of the optimization of a circuit, including modeling and programming difficulties encountered, is presented. A three transistor bandpass filter is used in order to study various methods of optimization. The adjoint method of calculating the network error gradient vector is compared to the perturbation method. The adjoint method proves to have decided advantages over the other method. A generalized computer program is presented to carry out the Fletcher-Powell optimization algorithm with specialized subroutines which include a network equation solver and both methods of finding the gradient vector. The program proved very effective in realizing a desired …

Effect Of Glass Aggregates Upon Abrasiveness Of Asphaltic Mixtures, Dwarka Prasad Gupta

Masters Theses

"The utilization of glass as an aggregate in asphaltic concrete pavements has been suggested as a means for reusing the increasing amounts of waste glass generated each year in the United States. Recent studies have shown that asphaltic mixtures containing glass aggregates can be designed to meet Marshall requirements for stability, flow and void content but the abrasiveness of mixtures containing glass aggregates had not been investigated. The objectives of this study were to develop a laboratory wear testing apparatus and compare the abrasiveness of asphaltic concrete mixtures using glass aggregates with the abrasiveness of mixtures using several different conventional …

Studies Of Neutron Capture Produced Rare Gas Isotopes In Rocks And Minerals Containing Chlorine, Selenium And Tellurium, David E. Sinclair

Masters Theses

"Noble gas mass spectrometry was used to study rare nuclear processes in terrestrial rocks and minerals. An excess of ³⁶Ar was detected in a chlorine-rich rock. The excess ³⁶Ar has been produced in rocks near the earth's surface due to capture of cosmic-ray-produced neutrons on ³⁵Cl. Measurement of ³⁶Ar formed by the ³⁵Cl(n, γ)³⁶Cl(β^-)³⁶Ar process makes possible a new method for determining the surface residence time of chlorine-rich minerals

Excess ⁸²Kr and excess ⁸³Kr were detected in selenium-rich ores. The excess ⁸²Kr results from double beta …

Design And Construction Of A Drop Generator For Use In A Vertical Wind Tunnel, Danny Ray Conner

Masters Theses

"A drop generator, based on the principle of a vibrating capillary, was designed and built for use in the UMR vertical atmosphere wind tunnel. The drop generator worked very well on a test stand where it was firmly supported, but was not consistent when tested in the wind tunnel. Vibration of the wind tunnel walls and a slight turbulence near the forward edge of the generator caused an oscillation in the position of the stream of drops. The oscillation resulted in some of the drops hitting the edge of the collector cup, where the drops would accumulate until a large …

Concentration By Sorting : Feasibility Determination By Radial Distribution Analysis, Robert M. Doerr

Masters Theses

"A method was developed for determining certain factors for assessing the feasibility of sorting fragments of an inhomogeneous solid to concentrate a species. These factors are the typical size of zones in which the grade exceeds a selected value, and the recovery potentially achievable by sorting fragments of such size"--Abstract, page iii.

The Use Of Behavior Modification To Control The Classroom Behavior Of Socially Maladjusted Junior High School Students, Jack L. Wheeler

Masters Theses

A base rate of disruptive and inappropriate classroom behavior was obtained for 40 junior high school children from a program for the socially maladjusted. Teachers involved with these subjects were given a six week in-service training program reviewing the basic techniques of operant conditioning. Parents of 12 subjects were trained in operant conditioning and were asked to use these techniques to control inappropriate behaviors of the subjects at home. When a social and token reinforcement program was introduced in the classroom for all 40 subjects, the frequency of disruptive and inappropriate behavior declined in all subjects. Withdrawal of the social …

The Effects Of The Four Psychological Primary Colors On Gsr, Heart Rate, And Respiration Rate, Keith W. Jacobs

Masters Theses

Measurement of GSR, heart rate, and respiration rate were taken on twenty-four male S's during presentation of four colors (red, yellow, green, blue). Four sequences of color presentations were used based on a 4 by 4 latin square with six subjects receiving each presentation. Significant color effects (p < .05) were found when GSR was used as the measure of activation. The most arousing color was red, followed by green, yellow, and blue, with significant differences in arousal value found between colors. Significant trial effects, disregarding colors, were found in respiration rate. No significant effects on heart rate were found as a function of trials or color. The arousal values of the colors do not support either a linear or U-shaped function of wave length.

An Investigation Of The Effects Of Specific Parameters On An Experimental Analogue Of The Anxiety Relief Hypothesis, Gary W. Hardy

Masters Theses

Thirty-two, naive, albino rats were randomly assigned to one of eight treatment groups with four members per group. The apparatus used was a modified one-way avoidance chamber developed by Baum (1965). The variables studied were the effects of a retraining anxiety relief condition, a hierarchical presentation of tone with the anxiety relief condition, different inter-trial intervals, and the interactions of these variables. All subjects were given the anxiety training to a ninety decibel tone and one-half of the subjects were given anxiety relief training. All subjects were trained to a criterion of ten consecutive avoidance responses in a one-way avoidance …

The Relationship Between Self Concept And The Draw-A-Person Test, William Maurice Schaefer

Masters Theses

This study sought to expand a study by Kamano (1960) to a normal population. In that work, Kamano used the D.A.P. in conjunction with the Semantic Differential. He concluded that the Ss (schizophrenics) analyzed their drawings consistent with their own self concepts. In the present study the relation between Ss ratings of the D.A.P., their self concept, and judges ratings of the drawings were sought. It was predicted that the Ss would rate themselves and the Drawings similarly. This prediction was upheld for the Potency factor. There was interjudge reliability for this factor, but the prediction that there would be …

A Comparison Of Analytical And Experimental Approaches In Determining The Thermoelastic Stresses Around A Cylindrical Inclusion Of Elliptical Cross-Section, Kenneth Byron Oster

Masters Theses

"Three approaches are used to determine the principal stress differences in an infinite elastic medium containing a cylindrical inclusion of elliptic cross-section due to a uniform temperature change. First, the two-dimensional equations of thermoelasticity are solved resulting in equations for the stress components anywhere in the medium material. Second, boundary displacements based on stress-strain relations are used as input displacements in a finite element program of the medium. Third, these same boundary displacements are used as input displacements on a photoelastic model simulating the medium. The problem is treated as one of plane strain in the first approach and one …
