Monte Carlo Simulation Of Confidence Intervals For Reliability, Kathryn Palisch Berkbigler

Masters Theses

"A computer program which computes fiducial confidence intervals for reliability by Monte Carlo simulation has been written. The program has the capability of computing these intervals for general systems of series, parallel, and mixed series and parallel subsystems which have failure time distributions which are either exponential, Weibull, gamma, normal, or lognormal.

Comparison of the simulation technique with a Bayesian technique for computing confidence intervals in the case of a series of exponentially distributed components shows that the two methods agree quite well when a fiducial prior distribution for reliability is used in the Bayesian technique. A uniform prior distribution …

Mass Transfer Coefficients Determined By Simplex Optimization Techniques, Charles Ferris Callihan

Masters Theses

"The objective of this thesis is to develop a method for obtaining individual mass transfer coefficients in absorption columns. There are two assumptions which apply throughout the thesis. The first assumption is "plug flow." The second assumption is that the axial concentrations can be measured accurately enough.

The problem is approached by simulating data generated from a mathematical model of an absorption column. A response surface is defined which is a function of the individual mass transfer coefficients. The lowest point on the surface locates the individual mass transfer coefficients for the system in question.

The mathematical model of the …

The Effect Of Explosive Charge Length Of Cratering, John M. Mason

Masters Theses

"In an attempt to determine the influence of charge length upon cratering, a series of small scale model blasting experiments were conducted in Plexiglas, Hydrostone, mortar and dolomite, using mild detonating fuse as the explosive charge. Single hole blasts were simulated, with the blasthole being drilled normal to one free face and parallel to a second. The resultant craters were photographed and closely studied. Particular attention was paid to effects of variation of charge length and burden upon cratering.

The investigation showed the importance of radial fracturing and the dominance of gas pressure in explosive crater formation from elongated cylindrical …

An Investigation Into The Degree Of Correlation Between Air Flow Rates, Bacteria In The Air And Post-Operative Infections In Hospitals, Carl Eugene Intag

Masters Theses

"Post-operative infections are a recognized problem in the medical and hospital professions. Annual costs and deaths due to infections in the U.S.A. have been estimated at $8-$9 billion and 10,000 lives respectively. The air lS one potential path in transporting contaminants that may cause an infection. Yet, the degree of influence airborne contaminants have in causing infections is a topic of much debate. As a result of the need for more information in this area, this investigation was undertaken to determine the degree of correlation between post-operative infection rates, bacteria in the air, and air flow rates.

The Linear New City -- A Pattern For New Cities Based On Efficiency Of Transportation, Public Services, And Land Use, Elbridge Wesley Bartley Iii

Masters Theses

"The linear new city is defined as a city consisting of some arrangement of relatively narrow, high-density strips, served by various mass transportation systems. Such a new city would be ideally suited to the implementation of the latest technology. The concentration of development along the transportation route would allow certain economies in the supply of utilities and services, as well as insuring that open space would be readily available around and throughout the city. The provisions for transportation, housing, and governmental control should combine to produce a better quality of life for the inhabitants of the linear new city"--Abstract, page …

Nutation Control During Precession Of A Spin-Stabilized Spacecraft, Richard James Donner

Masters Theses

"The effects of precession thrust pulses and energy dissipation upon nutation of a spin-stabilized spacecraft are studied. Methods for controlling nutation during a precession maneuver are proposed and examined. In particular, a precession modulation control law is developed which uses precession thrust pulses to control nutation. Digital simulations show that precession control with separate nutation control is the fastest precessing system; however, the precession modulation method is only fractionally slower while not requiring a separate nutation control system"--Abstract, page ii.

Multispectral Analysis Of Erts Imagery By Color Enhancement, John F. Peters

Masters Theses

"The Earth Resources Technology Satellite (ERTS) program has supplied the scientist with high resolution multispectral imagery of a large portion or the earth. Photographic and electronic methods of image enhancement are not universally available to those who might profit from such endeavors.

Diazo products were found to be satisfactory for creation of false color enhancement of ERTS multispectral data. The purpose of the enhancement was to make the Diazochrome composite comparable to more sophisticated methods for the purpose of interpretation. The basis of the enhancement was the standard false color infrared composite, with negative and positive Diazochrome masks to enhance …

Ideal Filter Approximation And Synthesis, Patrick Shu Yau Ho

Masters Theses

"Several methods are currently used for approximating the ideal low pass filter. Generally, those approximations relate only to the amplitude or phase characteristic of the ideal filter. A class of filters has been proposed as approximating both the amplitude and phase characteristics of the ideal filter. The characteristics of the first ten members of the proposed class are considered in this paper. The results indicate a much improved approximation to the ideal filter has been achieved"--Abstract, page ii.

Efficacy Of Reinforcement In An Observational Paradigm, Charles M. Krizic

Masters Theses

Study investigated the effectiveness of reinforcement in an observational paradigm where the dependent variable was indicated by increased morphological resemblance of an observer (O) after viewing a model (M). The stimulus was a series of novel responses recorded on videotape with each child viewing the tape individually. The subjects were 32 Head Start males divided into four groups. The first group was administered verbal praise prior to the modeling session. The second served as the vicarious reinforcement condition and observed an adult praise the model. The third group received direct reinforcement during the test for acquisition. The control group received …

An Electromyographic Study Of The Effects Of Lateral Asymmetry On The Upper Leg Muscles Used In Normal Walking On A Treadmill, S. Marie Landmesser

Masters Theses

The purpose of the study was to determine through electromyography whether a non-pathological fault, such as lateral asymmetry at the pelvic level, would hinder, in significant manner, efficient functioning of the body.

A review of the literature revealed that although previous experiments had been conducted to determine the effects certain postural deviations had on the normal, efficient functioning of the body and that previous experiments had been conducted to determine which muscles performed which task as related to walking, none dealt with the specific effects of lateral deviations at the pelvic level on the upper leg muscles used in walking. …
