An Analysis Of A Network Of Finite-Queue, Multiple-Server Facilities., Juanita Kaye Shukers Grau

Masters Theses

"An algorithm for listing all possible steady states and for generating the transition matrix for a series of finite-queue, multiple-server facilities is described. This algorithm is compared to a previously developed one. The new algorithm is better since it works for multiple servers and does not require an extra pseudo-facility. Using the list of states and the matrix generated by the new algorithm, exact steady state probabilities can be calculated. Then the probabilities can be used to obtain system statistics which cannot be calculated otherwise"-- Abstract, p. ii

Fluid Inclusion Geothermometry Of Tri-State Sphalerite, Chi-Sheng Wei

Masters Theses

"Fluid inclusions in successively deposited generations of sphalerite from the Tri-State district have been examined for geothermometry as a function of time. The main stage of vug-filling sphalerite has been studied most intensively and as many as 83 fluid inclusions have been examined in a single crystal. These sphalerite crystals are commonly zoned, and their filling temperatures exhibit a general pattern of declining temperature from their cores outward, from about 135°C down to 90°C. The decline is not a steady one, but rather it is characterized by fluctuations commonly about 15-20°C. Some fluctuations have magnitudes as great as 50-60°C, with …

The Social History Questionnaire As A Predictor Of Therapeutic Outcome, Susan E. Suter

Masters Theses

One of the most critical problems encountered in clinical practice concerns the outcome criteria used for predicting therapeutic improvement. At present, there is no single outcome criteria that is universally accepted as evidence of improvement. Representative studies by Lubarsky et al (1971) have emphasized the magnitude of this problem by citing the many patient variables that may effect the outcome of a therapeutic relationship.

The importance of this therapeutic relationship in terms of time and committment on the part of both the therapist and the client, necessitates some objective means for first, the development of an instrument that can measure …

Method Of Karyotype Determination For Cercaria: Application To Family Azygiidae (Trematoda), James Everett Mick

Masters Theses

The development of a method for karyotype determination of cercaria provides a basis for comparative karyotype analysis between cercaria and adult, possibly eliminating the need for infection experiments for positive identification of cercaria. Snails (Goniobasis livescens) were collected from below the spillway of Lake Charleston, on the Embarras River, near Charleston, Illinois. Of a total of 196 snails collected 42 (21.5%) were found to be infected with undetermined furcocyticercous cercariae. Infected snails were detected through isolation procedure. From the infected snails, emerged and non-emerged forms of the cercaria were recovered. Whole mounts of the cercaria were made and …

The Intramolecular Torsional Potential And Dielectric Properties Of 2,3-Butanedione, Gevert H. Meyer

Masters Theses

Dipole moment measurements have been carried out on 2,3-butanedione in solution, pure liquid, and the vapor phase. A dipole moment of 1.03 ± .01 Debye was observed for dilute solutions of 2,3-butanedione in carbon tetrachloride. Pure liquid samples exhibit an anomalous dipole of 1.56 ± .01 Debye. The following results were obtained for vapor phase measurements: 1.04, 1.07, 1.08, 1.11, and 1.17 ± .01 Debye at 310.15, 350.15, 370.15, 431.70 and 472.10 ± .02°K respectively.

The acetyl torsional potential was characterized from the observed temperature dependence of dipole moment. This torsional mode was described by a two-parameter potential function: V(Ø) …

Mmpi: An Attempt To Fake Profiles Of Policemen, Odie M. Swift

Masters Theses

Personality, uses of personality tests, and problems associated with reliability of personality tests are briefly discussed. The Kroger and Turnbull (1975) study dealing with "role-faking" is discussed. The review of the literature discusses the occupation of policeman under three categories: 1) assessment of policemen, 2) MMPI and police assessment, and 3) MMPI studies. The MMPI was given to 18 policemen, 43 male college students, and 40 female college students. The students were assigned to a control condition and an experimental condition. Subjects in the experimental group answered MMPI questions the way they thought policemen would answer the questions. An analysis …

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 Spheriodization Of Tool Steels., Siri Ram Rai

Masters Theses

"Four different tool steels--AISI 01, Sl, A9 and Tl5--were obtained in the 1/2-inch diameter hot rolled and air-cooled condition from the steel mill. The lower critical temperatures of these steels were determined. The spheroidization of each steel by three different spheroidizing procedures was evaluated with the use of hardness testing and metallographic techniques. Isothermal annealing completely spheroidized each steel yielding coarse carbides and low hardness. Cyclic annealing was an effective spheroidization procedure only for 01 and Tl5 steels. Hardening and tempering resulted in rather fine spheroidized structures in these steels. The total time consumed to produce the best spheroidized structures …

A Parametric Investigation Of The Validity Of 1/25 Scale Automobile Aerodynamic Testing., Marvin Eugene Doberenz

Masters Theses

"Wind tunnel tests have been performed measuring the aerodynamic forces and underbody boundary layer profiles for 1/25 scale models. The trends of the force coefficients with Reynolds number, the underbody boundary layer profiles, and the influence of the ground plane boundary layer on the force coefficients of small-scale models has been shown to be similar with previous results from larger models. This study has shown the usefulness of small-scale models for parametric studies of automobile aerodynamics. The agreement of the data with previous results, also supports the possih1lity o f a method of correction for boundary layer growth on fixed …

A Comparison Between Direct Waves And Head Waves In A Seismic Refraction Profile., Nelson Jose Aboud Garcia

Masters Theses

"The purpose of this investigation was to experimentally verify the theoretical prediction that the particle velocity of a head wave is the time integral of the particle velocity of a direct wave.

The procedure was to use small explosions in the field to generate direct waves and head waves in a surface layer of low compressional velocity overlying a higher velocity medium. The direct waves were distinguished by the ratio of frequencies and by the slopes in a time distance plot.

The result of comparing the particle velocity of the head waves with the integral of the particle velocity of …

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 …
