The Transition Of An Engineer To An Engineering Manager: The People Problem., Edward Leon Boyd

Masters Theses

“A review of existing literature and a survey of engineering managers are used to determine the work of the engineering manager, the career path leading to an engineering management position, and the skills that should be acquired by the engineer desiring to make the transition to an engineering management position.

The work of the engineering manager, like that of any manager, is getting things done through other people. In advancing to the first formal management position, the engineer usually passes through three career stages: engineer, informal manager, and formal manager. While advancing through these career stages, the engineer must increase …

An X-Ray Diffraction Analysis Of The Lacro₃-Laalo₃ Solid Solution Series, Robin Ashley Murphy

Masters Theses

"A crystallographic study was made of powders from the LaCr_1-x Al_xO₃, La_.90(Mg_.05 Cr_1-x Al_x )_.95O_2.83 , and La_1±xCrO₃ systems. The relationships between composition and thermal expansion, electrical conductivity, and vaporization were also investigated. The x-ray diffraction data of the LaCrCO₃ - LaAlO₃ compounds showed the system to form a single phase solid solution for any given sample from the series. The orthorhombic to rhombohedral phase transition was depressed to below room temperature at approximately 13% Al⁺³ substitution"--Abstract, page ii.

Development Of A Quadratic Finite Element Solution Of The Convective-Transport Equation., David A. Dillard

Masters Theses

"A quadratic finite element has been developed for the solution of the general three-dimensional convective-transport equation. Inherent instabilities in the numerical solution arise when the convective terms in the governing equation become significant. An application of upwinding techniques to the 20 degree of freedom serendipity element failed to produce acceptable results. Upwinding was applied to the 27 degree of freedom Lagrangian element with good results. Results of the latter element are given for several problems, including a model of a round to round metal forming process"--Abstract p. iii

Inferences On The Shape Parameter Of The Gamma Distribution And Cramer-Rao Lower Bounds From Censored Data, James Wyckoff

Doctoral Dissertations

"This dissertation is presented in publication form and consists of two articles. The first article considers inferential procedures on the shape parameter of a gamma distribution from censored sampling. Moments for the statistic T = log(x̅_r/x͠_r) are found and used to derive a two-moment chi-square approximation for T. This approximation is then used for testing, estimating, and setting confidence bounds on the shape parameter of a gamma distribution. The second article concerns the Cramér-Rao lower bounds for the variances of estimators, where the estimators are based on censored data. Convenient techniques are derived to evaluate the …

Some Selection And Ranking Procedures For The Two Parameter Weibull Distribution, Joseph Victor Kingston

Doctoral Dissertations

"This dissertation investigates some selection and ranking procedures for two or more Weibull populations. In particular it studies a restricted subset selection procedure when the populations have a common shape parameter, a 'pick the one best ' procedure for different shapes, classification procedures for both cases, simultaneous and 'best population' confidence intervals for both cases, and, finally, the problem of selecting the one population with largest or smallest shape. Except for the last problem named, the populations are ranked by their reliability. All procedures employ estimates of the parameters of interest based on either uncensored or Type II censored samples. …

Adaptive Control Of A Cloud Simulation Chamber Expansion System, Katiya Greigarn

Doctoral Dissertations

"This dissertation describes the design and construction of a closed-loop computer controlled expansion system for a cloud simulation chamber. The chamber is used to simulate atmospheric phenomena for the study of microphysical processes. In order to accomplish this, the sample gas inside the chamber must be expanded adiabatically. This means the wall temperature and the gas temperature must be made to agree as closely as possible. The wall is cooled by thermoelectric modules, and the temperature is controlled by analog controllers. The gas is cooled by the adiabatic expansion, and the corresponding pressure is controlled by a laboratory minicomputer, a …

A Hydrologic Analysis Of The Meramec River Basin, Missouri, Glendon Taylor Stevens Iii

Masters Theses

"The purpose of this study was to develop water budgets for the Meramec River Basin. These budgets, developed from average annual data, are quantitative assessments of the basin's water resources.

On a long-term basis, inflow was approximately balanced by outflow indicating that the system is steady state.

Precipitation was found to be the only substantial source of inflow to the basin and averages about 40 inches per year.

Evapotranspiration was found to be the major source of outflow from the basin. Annually it accounts for about three quarters of the total outflow and averages about 30 inches.

Streamflow was found …

Vehicle Detection Using A Magnetic Field Sensor, Stanley V. Marshall

Electrical and Computer Engineering Faculty Research & Creative Works

The measurement of vehicle magnetic moments and the results from use of a fluxgate magnetic sensor to actuate a lighting system from the magnetic fields of passing vehicles is reported. A typical U.S. automobile has a magnetic moment of about 200 A-m2(Ampere-meters2), while for a school bus it is about 2000 A-m2. When the vehicle is modeled as an ideal magnetic dipole with a moment of 200 A-m2, the predicted results from an analysis of the sensor-vehicle geometry agree closely with observations of the system response to automobiles.

Effect Of Collagen And Chloride Additions On Electrolytic Copper Deposits, William P. Lorenz, Thomas J. O'Keefe, Carlo B. Sonnino

Materials Science and Engineering Faculty Research & Creative Works

The effects of collagen concentration and molecular weight on the morphology and crystal orientation of electrolytic copper deposits have been determined and compared. The effect of chlorides in the presence of collagen on the above properties has also been investigated. Three different molecular weight collagens were studied and the consumption rate of each was determined by chemical analysis of the electrolyte before and after electrodeposition. Two-hour deposits were made in an electrolyte containing the subject collagens in concentrations ranging from 1.2 to 38.4 mg 1-1. Scanning electron and light microscopes and X-ray diffraction were used to evaluate the electrodeposits. © …

Spin Correlations In Actinide Materials: A Neutron Study Of Usb, G. H. Lander, S. K. Sinha, Don M. Sparlin, O. Vogt

Physics Faculty Research & Creative Works

Measurements have been made of the short-range spin correlations in USb, a metallic compound that orders antiferromagnetically. The system has no transverse fluctuations, and the longitudinal spin correlations are anisotropic, showing stronger interactions within the ferromagnetic sheets than between them. The results of this and other experiments can be understood with simple concepts involving the bonding of 5f electrons. © 1978 The American Physical Society.

Production Of Cl⁻·Hcl Cluster Ions In Hcl-N2 Mixtures, R. J. Corbin, Kaare J. Nygaard, William R. Snow, Laird D. Schearer

Physics Faculty Research & Creative Works

A drift-tube-mass-spectrometer apparatus has been used to study the production of Cl-·HCl cluster molecules in HCl-N2 mixtures. The concentration of HCl was 730 ppm and the total pressure ranged from 0.1-5 Torr. The primary ion Cl- is produced mainly by dissociative attachment of HCl and is converted to a cluster ion in a three-body collision. The rate of formation of the cluster ion is k2≃ 10-25 cm6/sec at E/N=12 Td. © 1978 American Institute of Physics.

Measurement Of Poisson's Ratio And Tangent Modulus Of A Loess, Craig Randall Bowers

Masters Theses

"A series of triaxial tests are used to develop mathematical models for tangent modulus and Poisson's ratio for a remolded loessial soil. These two models are then utilized in a finite element computer program to model the behavior of a shallow foundation placed on compacted loess. Different models for Poisson's ratio gave widely varying load settlement curves, however a constant value of .32 gave results very similar to that given by the experimentally developed model. It was found that the model developed for tangent modulus yielded unreasonable results when utilized in the finite element analysis until a limiting value was …
