Motion Of Viscous Liquid In Rotating Cylinder, Chicheng Wu

Dissertations

A computer model for the withdrawl and buildup of the fluid from the pool bounded on the horizontal, rotating, cylindrical surface has been developed. For a incompressible Newtonian fluid, the model is based upon the modified SOLA-SURF algorithm to solve the finite-difference form of Navier-Stokes equations on primitive variables. A hybird of centered and partial donor cell differencings is applied to the momentum convective flux. In each time cycle, the cell velocity is adjusted by the pressure corrector and iterates to satisfy the equation of continuity. The free surface position is approximated by a surface height function derived from kinematic …

A Needs Analysis Study For The Establishment Of A Community College Educational System In The United Arab Emirates, Hussain M. Joma

Dissertations

Although the United Arab Emirates (U.A.E.) survived for nearly a decade, its future is far from secure. Among the most immediate and pressing of the U.A.E.'s problems are those of manpower and trained personnel in technical and middle management.

The purpose of this study was to conduct a needs analysis for a community college educational system that will be established in the U.A.E. Underdeveloped nations have imported the idea of the community college concept to help them as they face new problems of modernization and growth.

The questions that were researched are as follows: (1) What are the educational plans …

Removal Of Fluoborate From Electroplating Rinse Water By Ion Flotation, Ray Haralson

Dissertations

A problem exists in the removal of fluoborate from electroplating waste rinse water. The normally used waste treatment methods are not effective and the vacuum evaporation process now being tried is expensive and energy intensive. Experiments were conducted and an alternative treatment process which shows substantial removals of the fluoborate was developed. This can be effectively done using ion flotation techniques. A broad range of surfactants were screened for usefulness in this process and it was found that an aliphatic amine acetate was usable in this process. Operating parameters for the process were investigated, and the removal mechanism was determined …

Fractionation Of Multicomponent Mixtures By Staged Sequence Cyclic Process And Parametric Pumping, Charles Omotayo Kerobo

Dissertations

The continuous fractionation of multicomponent fluid mixtures has been experimentally and theoretically investigated by staged sequence cyclic process and parametric pumping operating in the direct thermal mode.

A multicolumn staged sequence cyclic process for the separation of solute mixtures was developed. The criteria necessary for the continuous fractionation of a system of n solutes with n+1 columns arranged in a series operated with n+1 cyclic variables is presented. The feasibility for practical application of this process was demonstrated by fractionating the model system, O-xylene-Anisole-n-heptane on silica gel. The separation was modeled by one column staged sequence experimental data and by …

Separation Of Proteins Via Ph Parametric Pumping With Electric Field, Helen Conway Hollein

Dissertations

A new semi-continuous parametric pumping process for the separation of protein mixtures has been developed, based on cyclic variation of pH and electric field. The model system used for this process consisted of a mixture of human serum albumin and human hemoglobin in contact with CM Sepharose cation exchanger. Experimental results show that the protein separation via the pH parapump with electric field is two to three times greater than the results which are obtained in batch chromatography or via either single-column or multi-column parapumps with cyclic variation of pH and ionic strength.

The separation in the new process depends …

The Relationship Between Organizational Structure And Support For Employee Communication Skill Improvement, Roberta M. Supnick

Dissertations

In order to examine the relationship, if any, between an organization's structure and the propensity of that organization to support communication training for its employees, 16 small manufacturing firms located in southwestern Michigan were selected for study. Firms were determined to exhibit organic, mechanistic or mixed structures based on managers' perceptions of centralization, formalization, impersonalization and task specialization within the company. Each firm was also judged to exist in either an uncertain or stable environment. Support for communication training in each company was assessed from personnel directors' responses to questions concerning programs offered, employees involved, frequency of offerings and percentage …

Remote Attitude Measurement Techniques, Frank John Elmer

Dissertations

A method has been developed for solving practical problems which can be expressed in terms of physical geometry. These problems often involve combining directional information observed by remotely located sensors reported in their own respective local coordinate systems. To transform this information into a common coordinate system, the attitude of the sensors must be measured with respect to this common coordinate system.

Physical geometry is a generalization of mathematical -geometry where objects define the endpoints of figures composed of ensembles of lines. A probabilistic approach has been taken which is based on the fundamental assumption that the objects can be …

Crimp-Type Electrical Connectors, Ted Lai-Che Kuo

Dissertations

Three types of surface conditions (plain surface, plain surface with oxidation inhibitor, and toothed surface) and four types of environmental gases (air, nitrogen, hydrogen, and oxygen) were used to study the performance of electrical connectors installed on aluminum conductors. All of the connectors were placed insealed vessels which allowed the desired type of gas to flow at a steady rate. The connectors were then current cycled.

For the connections prepared with plain surfaces, the connectors deteriorated equally fast in air, nitrogen and hydrogen. Only the connectorsexposed to oxygen showed a higher deterioration rate than the others.

Connections prepared withhaving plain …

An Experimental Study Of Multiple Steady States In A Photopolymerization Reactor, Chih-Ning Kuan

Dissertations

An experimental study of photosensitized free radical polymerization of styrene in both batch and continuous stirred tank reactors is presented. Each reactor was run under both adiabatic and isothermal conditions. Multiple steady states were investigated. Exact multiplicity and uniqueness criteria for the above systems were derived and a mathematical model developed to correlate the results.

For both adiabatic and isothermal continuous stirred tank reactors operating in the metastable state regions, the conversion and polymer molecular weight are greater than the corresponding lower steady state operations. At a given conversion level, the reaction time for both adiabatic and isothermal continuous stirred …

The Entrainer Effect On Azeotropic Distillation Column Design, Charles Ming-Hsiao Tsai

Dissertations

A rigorous multistage distillation model was developed for use with non-ideal multicomponent systems. A subsidiary computer program was also developed to handle the problem of two liquid phases after condensation of a vapor.

Using the program developed, entrainer entry location and rate effects have been investigated via computer simulation for azeotropic distillation columns. The specific example used to verify the procedure was an ethanol dehydration column using benzene as the entrainer. The results indicate that the entrainer should enter the column two to five theoretical stages above the feed. The optimum entrainer rate was also determined.

The overhead vapor product …

A Model For The Development And Administration Of A Modern Television Complex For Private Colleges And Universities, Paul Henry Denton

Dissertations

Problem. There are virtually no model designs available for television complexes to meet the needs of private colleges and universities. These institutions must meet educational specifications for new or remodeled complexes within strict limits in space and money. The purpose of this study was to develop a model complex and administration of a cost efficient design.

Method. The study utilized the descriptive and developmental methods. Literature was reviewed to gather concepts related to complex facilities, hardware, administration and personnel. Twelve functioning television complexes were visited using a thirty-four item criteria list to evaluate each complex, its hardware, administrative structure, and …

Perceived Family Emotional Relationships, Person Orientations, And Expected-Job-Satisfaction Among Teachers In Training In Mexico : A Test Of Anne Roe's Theory Of Vocational Interest And Choice With The General Culture Group, Saul Torres

Dissertations

Problem. Anne Roe claims that occupational interests and person orientation develop to a significant extent from the complex interaction of family emotional relationships in the formative years. She describes three basic family patters (Accepting, Concentrating, and Avoiding) of needs satisfaction as antecedents to the two types of person oriention within eight occupational group classifications. Research has mostly failed to support her global occupational predictions. This study explored the specific predictions for a General Culture Group.

Method. A sample of 298 subjects was used from the population of 311 teachers in training at the University of Montemorelos, N. L., Mexico. …

Separation Technique On Proteins Via A Ph-Parametric Pump : A Theoretical And Experimental Study, Ura Pancharoen

Dissertations

The separation of protein mixtures via pH-parametric pumping was investigated both theoretically and experimentally. A simple system consisting of one column packed either with cation or anion exchanger was first considered. A system of parapumps was then developed with more columns which were connected in series and packed alternately with cation and anion exchangers. Various methods of operation of parapumps are discussed. Enrichment and spliting of protein mixtures were examined. In most cases, the separation factor was defined at a steady state condition and was improved by increasing the number of cycles and columns.

Computational methods for predicting both Batch …

Structural And Organizational Forces In The Etiology Of Corporate Crime, Beti Thompson

Dissertations

In an effort to gain understanding of the etiology of corporate crime, a theoretical framework for examining the problem has been developed. This framework includes structural features such as a capitalistic organization of society, the importance of political economy, the importance of market structure, and the importance of corporate influence over the legal environment, in understanding corporate crime. Corporations within this society are affected by the structural features of society. Organizations are organized according to capitalistic principles and effectively force their employees into certain kinds of actions and activities. It was theorized that such organizational factors might have an influence …

College Students' Attitudes Toward Affirmative Action Policies For Non-Whites And Women, Susan Ann C. Tong

Dissertations

This research was designed to assess college students' attitudes toward affirmative action policies for non-whites and women. As suggested by a review of the literature, five hypotheses were posited as possible factors related to attitudes toward antidiscrimination public policies. In addition, seven demographic variables were examined as control variables.

This study indicated that the majority of respondents were most in favor of equal opportunity and least in favor of discrimination-in-reverse. However, there were significant differences toward affirmative action based on the race and sex of the respondents. Non-whites overwhelmingly supported discrimination-in-reverse and did not favor equal opportunity. The converse was …

A Nonvocal Method For Teaching Reading And Spelling To The Deaf, Amy A. Barmeier

Dissertations

Teaching reading and spelling to the deaf requires materials and methods which compensate for the two problems of the deaf child. The first is that the deaf typically have a small verbal history in either the sign language or lipreading modes. The second is that the deaf cannot identify unknown written words by phonetically sounding them out. In comparison, the hearing child has sophisticated sounding out skills and an extensive auditory-vocal history.

The seven experiments in this research investigated a method for teaching vocabulary comprehension and spelling to the deaf which assumed neither a verbal history with respect to the …

Peer Training Of High-Risk Low-Frequency Staff Behaviors In An Institutional Setting, Richard Aart Van Den Pol

Dissertations

Four experienced and four newly employed psychiatric attendants were assessed on their performance of three high-risk low-frequency behaviors during simulated emergencies. The three skills measured were Convulsive Seizure Management, Fire Safety Procedures, and Self-Defense. Each of the behaviors directly affected the safety and well-being of staff and retarded residents of the facility. The experienced employees, labelled "Trainers", received a series of workshops on how to perform and teach the requisite skills to other staff. Following each workshop, according to a multiple baseline across skills experimental design, the Trainers each taught one new staff member, labelled "Trainee" how to perform the …
