Gold-Encrusted Chaos: An Analysis Of Auschwitz Memoirs, Mary D. Lagerwey

Dissertations

One way to better understand the Holocaust is to look closely at several survivors' stories. In my dissertation I closely examine six published memoirs of women and men from one time and place: Auschwitz, 1942-1945. Specifically, I ask three questions:

1. How do Holocaust memoirs relate a universal human story?

2. How are Auschwitz memoirs informed by gender?

3. How do Auschwitz memoirs exemplify a polyphony of voices which engulfs and transcends gender differences?

In exploring the first question, I develop a thesis, that there is a universal story which captures the experiences of Auschwitz survivors' experiences. Next, I develop …

Reducing Dietary Fat And Cholesterol Consumption: An Evaluation Of A Behaviorally Focused Nutrition Education Program, Peter F. Carey

Dissertations

Coronary heart disease (CHD) is the leading cause of death in the United States, killing more than 500,000 people annually. Serum cholesterol is a principal risk factor for the development of atherosclerosis, a primary precipitant of CHD. Unfortunately, elevated serum cholesterol is a common but often undetected health risk for many Americans. Furthermore, the typical American diet contains high levels of fat and cholesterol which contribute to elevated serum cholesterol levels. The National Cholesterol Education Program (NCEP), created to improve awareness of serum cholesterol as a CHD risk factor, recommends that dietary changes constitute the initial step in the treatment …

A Previous Suicide Attempt As A Factor To Predict Successful Completion Of A Residential Alcohol Treatment Program, Michael William Glover

Dissertations

The focus of the study was an examination of patient reports of a prior suicide attempt(s) as a predictor variable in completing a residential alcohol treatment program. Data were extracted from the records of 308 patients diagnosed as alcohol dependent based on criteria from the DSM III-R (APA, 1987). Additional demographic information, i.e. age, race, marital status, employment status, and substance use in family of origin, was collected for comparison to completion rates and prior suicide attempts.

Previous suicide attempt(s) was a statistically significant predictor for noncompletion of an alcohol treatment program for this study. The demographic factors of employment …

Particle Dynamics Modeling Of Vibrating Granular Beds, Yidan Lan

Dissertations

Particle dynamics modeling is done to study the behavior of granular beds subjected to vibrations imposed by a plane boundary which oscillates sinusoidally about a zero mean speed. Significant differences between the lower and higher shaking acceleration regions are found for the granular temperature and solids fraction depth profiles, which characterize the effectiveness of the boundary in fluidizing the beds. When higher accelerations are applied, the temperature is maximum at the vibrating floor and attenuates through the depth, while the solids fraction profiles exhibit a maximum at some intermediate depth. At lower acceleration values, most of the mass is located …

Motion Estimation Using Optical Flow Field, Jingning Pan

Dissertations

Over the last decade, many low-level vision algorithms have been devised for extracting depth from intensity images. Most of them are based on motion of the rigid observer. Translation and rotation are constants with respect to space coordinates. When multi-objects move and/or the objects change shape, the algorithms cannot be used.

In this dissertation, we develop a new robust framework for the determination of dense 3-D position and motion fields from a stereo image sequence. The framework is based on unified optical flow field (UOFF). In the UOFF approach, a four frame mode is used to compute six dense 3-D …

Adaptive Nonlinear Control Using Fuzzy Logic And Neural Networks, Shu-Chieh Chang

Dissertations

The problem of adaptive nonlinear control, i.e. the control of nonlinear dynamic systems with unknown parameters, is considered. Current techniques usually assume that either the control system is linearizable or the type of nonlinearity is known. This results in poor control quality for many practical problems. Moreover, the control system design becomes too complex for a practicing engineer. The objective of this thesis is to provide a practical, systematic approach for solving the problem of identification and control of nonlinear systems with unknown parameters, when the explicit linear parametrization is either unknown or impossible.

Fuzzy logic (FL) and neural networks …

Estimation And Cancellation Of Friction In Control Systems, Sofia Mentzelopoulou

Dissertations

The research reported in this dissertation concerns the estimation and cancellation of friction in control systems. For purposes of analysis, the Coulomb friction model, the "extended" Coulomb friction model as well as dynamic friction models are used. In addition, for systems with multiple degrees-of-freedom, a general matrix representation of friction is presented.

For the design of the friction estimators, the theory of nonlinear observers is applied. In particular, for a system with multiple degrees-of-freedom, holonomic constraints, and multiple friction sources, three different observers are presented to estimate the friction force or torque. The first (Generalized Coulomb Friction Observer) is designed …

Investigation Of Paraelectric Ptl Thin Films Using Reactive Magnetron Sputtering, Hyun Hoo Kim

Dissertations

The study of methods to prepare paraelectric perovskite PLT (Pb_1-xLa_xTi_1-x/4O₃; x=0.28) thin films has been important because thin films of this high dielectric strength material are required to make high density capacitors for dynamic random access memory. In this research, paraelectric PLT thin films were prepared on multi-layer (Pt/Ti/SiO₂/Si) and MgO substrates in a unique way by the reactive magnetron sputtering method using a multi-component metal target. The individual control of each metal area on the sputtering target had considerable influence on the stoichiometry and electrical properties of the thin …

Engineering Analysis Of A Packed-Bed Biofilter For Removal Of Volatile Organic Compound (Voc) Emissions, Zarook M. Shareefdeen

Dissertations

This study dealt with removal of VOC emissions from airstreams using an evolving new technology which is known as biofiltration. The basis of this technology is biodegradation of VOCs in biofilms formed around porous solids which are placed in packed-bed reactors.

A detailed model describing steady state biofiltration of single and mixed VOCs was developed, and experimentally validated. The model takes into account biodegradation kinetics, the effect of oxygen, kinetic interactions among structurally similar compounds, and mass transfer from the gas phase to the biolayer. It was found that oxygen (a factor neglected in all previous studies) plays a very …

Biological Denitrification : Fundamental Kinetic Studies, And Process Analysis For Sequencing Batch Reactor Operation, Jun-Hsien Wang

Dissertations

This study dealt with a detailed investigation of biological denitrification of nitrate and nitrite by a pure culture of Pseudomonas denitrificans (ATCC 13867), under anaerobic conditions.

In the first part of the study, the kinetics of denitrification were studied in serum-bottle experiments. It was found that reduction of both nitrate and nitrite follows inhibitory expressions of the Andrews type. It was also found that when nitrite is present at levels above 15 mg/L, nitrite and nitrate are involved in a cross-inhibitory, non-competitive, interaction pattern. Analysis of the kinetic data has shown that the culture used has severe maintenance requirements, which …

Heart Rate Variability Study Using Phase Response Curve, Peizhuan Zhang

Dissertations

A noninvasive phase resetting experiment on human subjects was investigated. The phase response curve was estimated and was used to demonstrate cardiac phase resetting due to a vagal input. The estimated running phase response curve showed that the cardiac cycle resetting depended on the time and the amplitude of the vagal stimulation. The phase response curve was then studied using time circle analysis, topological analysis and nonlinear dynamics analysis. Also phase entrainment and stimulus frequency dependence of the phase response were evaluated. Further, the Van Der Pol model, Generalized Additive model and Knight and Peskin's model were used to simulate …

There were five women and five men in the study who also reflected diverse ethnic and spiritual perspectives. The researcher used a qualitative interview methodology. Each person was given the chance to review and edit the transcript of the interview. …

Motion Synthesis Of Mechanisms Using Constraint Manifolds In Image Space, Yeou-Kai Wu

Dissertations

Kinematic mappings, quaternion algebra, and constraint manifolds in the algebraic image space are applied to the problems of the dimensional synthesis of mechanisms. Dimensions of a mechanism are determined such that a tracer frame fixed on the coupler will pass through or at least as close as possible to the desired positions and orientations in the physical space as the input link rotates about its fixed joint. First, using kinematic mappings, the desired positions and orientations of the tracer frame of the mechanism can be mapped onto points in a hyperspace in which the motion of the tracer frame can …

Behavior Of Biaxially Loaded Concrete-Encased Composite Columns, Pedro Ricardo Munoz

Dissertations

The theory of nonlinear behavior of biaxially loaded short and slender composite columns is used to study the load-deformation and moment-curvature of four pin-ended composite column specimens tested under axial compressive load and biaxial bending moments in a single curvature. The accuracy of the test results is verified by comparison with analytical results obtained by a method of analysis that includes the nonlinear material properties of concrete and steel and covers the ascending and descending branches of the linear segmented column specimen. A computational method is presented to model the analytical behavior of the biaxially loaded composite column. Its validity …

"I’Ll Do It Tomorrow." A Radical Behavioral Analysis Of Procrastination, Cassandra Ann Braam

Dissertations

This study examined the problem of procrastination or the failure to complete tasks. Five similar rules were presented to five, four-year-old children, using a multielement design. The rules described contingencies varying in the specification of delays in the delivery of consequences and deadlines. In addition, a general statement of disapproval of procrastination was presented one time, in addition to a rule specifying a delayed consequence with no deadline, to determine its effect on an established pattern of procrastination. The results showed (a) rules specifying delayed consequences (indirect-acting contingencies) with no deadlines did not reliably control behavior, (b) rules specifying immediate …

The Effects Of Utilitarianism On Performance Appraisal And Selected Output Measures In A Weberian Bureaucracy, Donald Wayne Wright

Dissertations

The research explored whether or not a relationship existed between the performance appraisal criteria used by the Social Security Administration and actual performance between 1984 and 1990. The issue was whether or not either of the diverse sets of performance appraisal criteria was more effective in improving performance than the other and whether or not base pay should be tied to the results of the performance appraisal system.

The methodology for this study was both quantitative and qualitative. The qualitative technique of content analysis was done on the sets of performance appraisal criteria to assess the extent to which each …
