Contractor Quality Control: A Method Of Construction Inspection, John Scott Treadwell

Masters Theses

"It has become apparent in recent years that the United States Government's construction contract supervision and administration procedures are causing an increase in contractor claims and disputes and that the system itself is becoming prohibitively expensive. To deal with some of these problems, the Department of Defense is attempting to implement a new approach to construction inspection--Contractor Quality control. Under the Contractor Quality Control System the majority of the standard contract inspection and testing responsibilities are placed on the contractor, and the Government relinquishes its traditional step-by-step inspection and testing procedures and withdraws to a position of contract surveillance. The …

The Cytogenetics Of The Salivary Gland Chromosomes Of Three Wild Type Strains Of Drosophila Melanogaster, Rosemary Ann Harris

Masters Theses

This investigation involves the cytogenetics of three strains of field-collected, wild-type Illinois Drosophila melanogaster. These three strains were collected from Charleston, Channahon, and Olney, Illinois, in 1967.

The purpose of this study was to compare cytogenetically these three strains and to determine if there exists differences among them. First, the chromosomes themselves were studied for the purpose of identifying the four chromosomes of D. melanogaster by their characteristic banding patterns. Then, the chromosomes of the three strains were examined for chromosomal aberrations, principally inversions. The cytogenetics of the chromosomes of the three strains were then compared and contrasted.

Comparison Of Diffusion Coefficients Measured Electrochemically And Non-Electrochemically, Terry Dick Rotsch

Masters Theses

Diffusion coefficients of Co(en)₃I₃⋅H₂O, FeCl₃, and K₃Fe(CN)₆ were measured using the methods of polarography, chronopotentiometry, and diaphragm cell for the purpose of determining any relationships which may exist between these values. A major objective of the present study was to relate diffusion coefficients obtained by a simple non-electrotrochemical method to diffusion coefficients used in electrochemical techniques.

It was found that the polarographically determined diffusion coefficients were all 1.04 times larger than the chronopotentiometric values. This constant factor is probably due to viscosity differences tn the polarographic and chronopotentiometric solutions …

Mechanical Properties Of Low Carbon Martensite, Allen L. Affolter

Masters Theses

"Steels of three different compositions were heat treated and tensile tested in order to determine their mechanical properties after heat treatment. All samples had near 0.20 per cent carbon and two manganese levels 0.90 per cent and 1.35 per cent. One group containing the higher manganese level also had small additions of columbium and vanadium. The specimens were too brittle in the as-quenched condition to be loaded to full strength. Maximum strength and ductility were found after short time tempering at low tempering temperatures -- 2 to 15 minutes at 200º to 300ºF. Higher strengths were found at the low …

Practical Application Of Digital Computer To Distribution Systems, Juan Vincente Saavedra

Masters Theses

"Given a three phase ac power distribution system, a digital computer program is presented which determines a complete steady state solution for a given condition. The network data is processed by the computer into an admittance matrix, and these parameters are stored in a manner that enables the computer program to operate upon them as the coefficient of a simultaneous set of nonlinear equations. This set of equations are solved by the Gauss-Seidel Iterative Process improved by a modification of the relaxation method. Practical experience with the distribution system of the Davenport, Iowa, plant of the Aluminum Company of America …

The Influence Of Member Length On Thermal Contact Resistance In A Vacuum Environment, Larry Martin Cooper

Masters Theses

"An investigation was conducted to determine the influence of member length on thermal contact resistance in a vacuum environment. A model was created which consisted of a center rod axially loaded between two other members. It was assumed that circular macroscopic constriction areas were formed at the contact interface when the rods were loaded. Macroscopic modeling of the contact surfaces makes the thermal contact analysis a function of the mechanical and thermal boundary conditions of the total body. The method of finite differences was employed to calculate the temperature distribution, heat flows, and thermal contact resistance of each member. Data …

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 …

Low Frequency Lumped Element Directional Couplers, Constantine Rodolph Jenkins

Masters Theses

"Lumped element directional couplers are desirable at frequencies below the VHF range because they eliminate the large physical size necessary for the distributed element directional couplers. The purpose of this work is to describe the theory and design of such low frequency lumped element directional couplers. A model for the coupler is developed and the equations which describe it are derived. Scattering matrices for one and two section couplers are obtained. Computer solutions for three section couplers are presented. Experimental results for one, two, and three section couplers are presented and comparison with theory are made. Comparisons of theoretical and …

A Statistical Hydrologic Simulation Model, Ronald L. Wycoff

Masters Theses

"Simulation of a physical system requires knowledge of all components of the system and their interactions. A probabilistic simulation model of a hydrologic system is developed from short term continuous, sychronized rainfall-runoff records. The individual components of the system area the time between and duration of storms, the depth of rain occurring in each time period of the storm, precipitation excess relations, and the watersheds unit hydrograph. The available data is used to define or develop the probabilistic models involved. The only nonprobabilistic model employed is the watersheds unit hydrograph. It is found that the time between and duration of …

A Study Of The Void-Strengthening Of Aluminum And Its Nature, Purushottam G. Manusmare

Masters Theses

"Strengthening of aluminum by formation of the voids and the nature of resultant strengthening, viz., the temperature and the strain rate dependence of its yield strength were studied. Aluminum wires with 99.999% purity and of 3.1 mm diameter were quenched and heat treated to form voids of the approximate density 10¹³-10¹⁴ voids/cm³ and were tested for their yield strength. Voids in selected samples were observed by transmission electron microscopy using the Hitachi HU-11A microscope. The yield strength of the void strengthened samples was measured at various temperatures from 77ºK to 593ºK using two strain rates, 3.33 x 10⁻²/sec and 1.67 …
