Probability Polynomials For Cubic Graphs In The Framework Of Random Topological Graph Theory, Esther Joy Tesar

Dissertations

Topological graph theorists study the imbeddings of graphs on surfaces (spheres with handles). Some interesting questions in the field are on w hat surfaces can a graph be 2 -cell imbedded and how m any such imbeddings are there on each surface. The study of these and related questions is called Enumerative Topological Graph Theory. Random Topological Graph Theory uses probability models to study the 2-cell imbeddings. It generalizes the results from Enumerative Topological Graph Theory (which is the uniform case, p= 1/2) to an arbitrary probability p.

We study the model where the sample space consists of all labeled, …

A History Of The Concept Of Creativity In Western Nursing: A Cultural Feminist Perspective, Karen K. Fritz Dnsc, Ms, Ba, Rn

Dissertations

Using historical methodology, this study examined the concept of creativity in Western nursing from a cultural feminist perspective. An exploration of the concept was accomplished by means of a review emanating from the English literature of Western nursing and its allied disciplines of education and psychology. Two distinct views of creativity were delineated--the classical and the contemporary. The classical understanding required the completion of a major product or attainment in order for creativity to be ascribed. In contrast, the contemporary view was that of a novel, unrestrained thought process. It required no creative work or attainment for its ascription. The …

Micromechanics Of Hot Mix Asphalt Material Formulation And Numerical Simulation, Kuo-Neng G. Chang

Dissertations

Hot Mix Asphalt (HMA), a highway and airfield pavement material, is heterogeneous, granular, and composite. It is traditionally modeled as a homogeneous material using continuum mechanics or semi-empirical methods. As a result, the above models either neglect or over-simply component reactions, failing to predict field performance problems resulting from particle segregation. This research presents micromechanical modeling, a novel approach that accounts for the components.

A micromechanical model is developed for HMA by modeling it as an assembly of asphalt cement coated particles. The asphalt cement is modeled as a viscoelastic material. To represent asphalt cement, several viscoelastic elements (i.e. Maxwell, …

Contingency-Shaped Behavior And Rule-Governed Behavior: A Comparison In Terms Of Speed Of Acquisition, Generalization And Maintenance, Ronald Ramirez-Henderson

Dissertations

According to Skinner (1969, 1974), operant behavior can be acquired through two major processes, direct contact between the behavior and its environmental consequences and antecedents in a process referred to as contingency - shaped behavior (CSB) and through verbal mediation by rules and instructions in a process referred to as rule-governed behavior (RGB). CSB and RGB were compared in terms of the speed of acquisition of complex problem skills, the generalization of those skills to new stimuli, and their maintenance. Forty-four college students, 13 males and 31 females, with an average age of 21 .5 years, participated in four sessions …

Toward A Biocritical Sociology, John Neuhaus

Dissertations

This dissertation is a critical discourse with three prominent trends in contemporary sociology. It is a critique of Emile Durkheim's admonition that sociological analysis, by definition, requires the exclusion of biological and psychological data. It shows, in contrast, that the exclusion of biosocial data removes vast sources of information which are useful and necessary in any interpretation of human behavior. This work also demonstrates that a biosocial perspective facilitates the development of a transcultural theory of human needs, which, if utilized, would enable sociologists to clarify a number of unproductive disciplinary conflicts concerning the definition and extent of social problems. …

On Adaptive Code Division Multiple Access Detectors, Wenping Chen

Dissertations

Several variations of adaptive CDMA synchronous receiver schemes which can automatically adjust to the system parameters, are studied in this dissertation. Unlike their non-adaptive counterparts, these adaptive detectors require no knowledge of the received signals' energies and have similar or better performance.

Minimum energy and decorrelating criterion are used to update the weights. Since weights are updated according to the changes of the detector's outputs, hence no training sequence is required. The convergences of some of the aforementioned adaptive detectors are also disscussed.

The detectors proposed in this dissertation are near-far resistant,thus rendering the high-precision power control unnecessary. Among them, …
