Effective Changes In Hospital Patient Accounting Since The Prospective Payment System (Pps), Carol L. Francke

Dissertations

This is a multiple case study that examined three hospital patient accounting departments since the adoption of the prospective payment system (PPS). The cases were chosen based on similarities such as their size and dependence on government programs for reimbursement, interviews were conducted and documents were reviewed from 1985 and 1990. Measures of gross revenue days in accounts receivable and the ratio of the number of full time equivalents (FTEs) to patient encounters were used to determine whether these patient accounting departments were more efficient in 1990 than in 1985.

Despite their selection of different forms of adaptation, all three …

Isospectral Graphs And The Expander Coefficient, Ian Campbell Walters Jr.

Dissertations

The expander coefficient of a graph is a parameter that is utilized to quantify the rate at which information is spread throughout a graph. The eigenvalues of the Lapladan of a graph provide a bound for the expander coefficient of the graph. In this dissertation, we construct many pairs of isospectral graphs with different expander coefficients.

In Chapter I, we define the problem and present some preliminary definitions. We then introduce two constructions that are related to graph composition and that may be employed to produce cospectral and isospectral graphs.

In Chapter II, we investigate the connectivity of and distance …

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

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 …
