Evolution And Application Of A Parallel Algorithm For Explicit Transient Finite Element Analysis On Simd/Mimd Computers, Partha S. Das

Electronic Theses and Dissertations 1990 - 1999

The development of a parallel data structure and an associated elemental decomposition algorithm for explicit finite element analysis for massively parallel SIMD computer, the DECmpp 12000 (MasPar MP-1) machine, is presented, and then extended to implementation on the MIMD computer, Cray-T3D. The new parallel data structure and elemental decomposition algorithm are discussed in detail and is used to parallelize a sequential Fortran code that deals with the application of isoparametric elements for the nonlinear dynamic analysis of shells of revolution. The parallel algorithm required the development of a new procedure, called an 'exchange', which consists of an exchange of nodal …

Extending Use Cases And Interaction Diagrams To Develop Distributed System Architecture Requirements, John C. Hawkins

Electronic Theses and Dissertations 1990 - 1999

Current object-oriented development methodologies do not introduce distributed system architectural aspects early enough in the system development cycle. A development partitioning scheme that includes the system level, in addition to the problem and application levels, will encourage analysis that includes elicitation of non-functional system requirements. These requirements include response time with respect to system communication load, fault tolerance, safety, security, and real-time deadlines, among others. They can be documented with an extended form of Jacobson's use cases. Where use cases describe how a system will work from a user's point of view, extended use cases add the capability to describe …

Exploratory Study Of Biofeedback In Reducing Pain After Thoracic Surgery, Laurie R. Angel

Electronic Theses and Dissertations 1990 - 1999

This study is a pilot concerning the relationship between acute pain management and biofeedback training. The population studied included patients from a local community hospital undergoing coronary artery bypass graft surgery. The study applied theories of the mind/body connection and stress frameworks for exploring the correlation between patients' hand temperatures and their reported levels of pain pre-operatively and post-operatively. Study findings indicated that there was significant within-subjects effect in hand temperature after biofeedback treatment across three points in time. But the study also found no difference between-subjects in hand temperature after biofeedback treatment across three points in time. Therefore, the …

Female Identity In The Novels Of Marge Piercy, Darcy Dianne Gordon

Electronic Theses and Dissertations 1990 - 1999

Women have traditionally formed their identity around standards created by a patriarchal society. In this way, they have often denied themselves autonomy and the process of self-discovery. With this knowledge, Marge Piercy through fiction re-imagines "the traditional female concern with personal relationships and the details of daily life and then expand (s) these concerns to include a wider and wider swath of human experience" (Snitow 719). Most of Piercy's novels intertwine politically motivated plots with female characters who reach a new conscious level of understanding about origins of identities, and thus these characters engage in an awareness that allows them …

From "Sincere Gay Woman" To "Busty, Fem Biwf": A Longitudinal Test Of The Generalizations About "Lesbians", Social Class, Feminisms And Butch And Fem, Sara L. Crawley

Electronic Theses and Dissertations 1990 - 1999

Academic and non-academic authors argue that middle-class lesbians present themselves as butch or fem less than working-class lesbians. Theorists also have argued that butch and fem were discoursed by 1970s feminist stigma but are reemerging in post-feminist decades. By analyzing "women seeking women (WSW)" personal ads, this study provides a longitudinal, quantitative analysis of the validity of these assumptions. The results suggest that middle-class lesbians were less likely to present themselves as butch or fem than working-class lesbians. Also, butch and fem were found to be much more prevalent in the 1990s than in the 1970s or 80s. Generational cohorts …

For God And Country: W. T. Stead And The Beginnings Of The New Journalism In Victorian Britain, 1883-1885, Phillip Michael Guerty

Electronic Theses and Dissertations 1990 - 1999

Since the late nineteenth century, scholars and historians have attributed the growth of a sensational press in Britain to long-term societal changes such as the rise of capitalism. What has been ignored, however, is the importance of individual initiative, mainly that of W. T. Stead of the Pall Mall Gazette. During the Sudan Crisis of 1883-1885, Stead introduced a new type of journalism to England that combined typographical innovations, such as maps and striking headlines, with a lively literary style. At the root of this new type of reporting were Stead's deep-felt convictions about spreading Christianity, extending the empire, and …

Florida Local Government Compliance With Transportation Concurrency, Raymond A. Liberti

Electronic Theses and Dissertations 1990 - 1999

Growth management grew as a concept and policy objective in the 1970s and 1980s. The interrelationships of the state and local governments changed when Florida developed growth policy and local government implemented the policy. Nine mandatory elements to be included in a local comprehensive plan and seven mandatory concurrency elements of the 1985 Florida Growth Management Act were expensive elements for local government to implement. As a result, the issue of funding the impacts of growth drove the growth management agenda, leaving the question of compliance. The question is: Did Florida local government comply with the transportation concurrency element of …

Generating Formal Models From Uml Class Diagrams, Malcolm Keki Shroff

Electronic Theses and Dissertations 1990 - 1999

The rich structuring mechanisms, and abstract modeling constructs available in most graphical object-oriented modeling methods (OOMs) facilitate the creation of abstract, visually-appealing, highly-structured graphical models. On the other hand, lack of formal semantics for the modeling notation can severely limit the utility of OOMs. Formal specification techniques (FSTs) support the creation of precise and analyzable specifications, but they can be tedious to create and difficult to read, especially by system developers not trained in formal methods. The complementary strengths of OOMs and FSTs suggest that their integration can result in techniques that can be used to create precise and analyzable …

General Relativistic Neutrino Transport In Static Post-Collapse Stellar Cores, Kenneth R. Denisco

Electronic Theses and Dissertations 1990 - 1999

We examine the effects of general relativity on neutrino transport during the critical shock reheating phase of core collapse supernovae. We derive the equations for general relativistic, static, multi-group, flux-limited diffusion (MGFLD), and use these to modify a Newtonian MGFLD code. The steady-state neutrino distributions calculated by the revised code for several post-collapse stellar cores are compared to those computed with the original Newtonian MGFLD code. The general relativistic transport calculations display the expected reductions in neutrino rms energy and luminosity arising from redshift and curvature effects. Although the effects of general relativity on neutrino transport work against the shock …

Image Ratioing As Appropriate Technology For Monitoring Vegetation Cover In The Caribbean, Justine Louise Delahunty

Electronic Theses and Dissertations 1990 - 1999

Satellite image processing should not be dismissed as a tool to monitor vegetation cover because of cost concerns or classification problems due to topographic extremes. Low cost imagery and image processing software's are available and the image ratio technique can be used to minimize classification problems due to topography. The Forestry Division of St. Vincent island has minimum resources and the island's topography varies from sea level to 1,324 meters. The plight of the endemic, endangered St. Vincent Parrot (Amazona guildingii) was used as a case study. An appropriate habitat monitoring technique was formulated for the Forestry Division so that …

Simultaneous Pressure-Temperature Measurements In A Heat Pipe, Madhavan. Jayanth

Electronic Theses and Dissertations 1990 - 1999

When a heat pipe operates with a large temperature difference between the two ends, the vapor liquid combination is not in thermodynamic equilibrium. The experiments showed that the vapor liquid mixture is in a higher state of saturation at the condenser as compared to other sections of the pipe. Correlations were obtained that relate the coefficient of thermal coupling alpha to the evaporator flux and mass of NCG (non-condensable gas). As mass of NCG is increased in the heat pipe, the thermal coupling coefficient alpha decreases. The evaporator heat flux is directly proportional to alpha. The coefficient alpha is related …

Software Reliability Engineering: An Evolutionary Neural Network Approach, Robert. Hochman

Electronic Theses and Dissertations 1990 - 1999

This thesis presents the results of an empirical investigation of the applicability of genetic algorithms to a real-world problem in software reliability--the fault-prone module identification problem. The solution developed is an effective hybrid of genetic algorithms and neural networks. This approach (ENNs) was found to be superior, in terms of time, effort, and confidence in the optimality of results, to the common practice of searching manually for the best-performing net. Comparisons were made to discriminant analysis. On fault-prone, not-fault-prone, and overall classification, the lower error proportions for ENNs were found to be statistically significant. The robustness of ENNs follows from …

Sparse Volume Array For Imaging Ocean Ambient Noise In The Near-Shore Region, Marc P. Olivieri

Electronic Theses and Dissertations 1990 - 1999

Ocean ambient noise has been studied extensively in the past, and several models have been developed to predict its level and to characterize it in different ocean environments. However, most of these studies have been motivated by the need to reduce the negative effect of the ambient noise on measurements. Recently, several studies have used the ambient noise to obtain information about the ocean floor and to achieve passive target detection. This dissertation describes the development of an Ambient Noise Sonar (ANS) which can be used to measure ambient noise directivity to obtain information about the environment. The system was …

Software Metrics Collection: Two New Research Tools, Sylviane G. Jordan

Electronic Theses and Dissertations 1990 - 1999

Collecting software metrics manually could be a tedious, inaccurate, and subjective task. Two new tools were developed to automate this process in a rapid, accurate, and objective way. The first tool, the Metrics Analyzer, evaluates 19 metrics at the function level, from complete or partial systems written in C. The second tool, the Call Graph Generator, does not assess a metric directly, but generates a call graph based on a complete or partial system written in C. The call graph is used as an input to another tool (not considered here) that measures the coupling of a module, such as …

Statistical Modeling Of The Container Inventory Control In A Distribution Network, Weiming. Feng

Electronic Theses and Dissertations 1990 - 1999

The study of the reusable container inventory control in a distribution network is crucial to the efficiency and cost effectiveness of the transportation systems. In order to minimize the total operation cost of such a transportation network system, all subsystems of the distribution network have to be optimized together as a whole system. In this study, we extended the inventory control concept and developed a multiple-inventory control model for the transportation network. We presented a systematic approach to address all those subsystems as interrelated systems. Mathematical models were developed for the transportation and container inventory control problems first. Then, the …

Microwave Plasma Chemical Vapor Deposited Diamond Tips For Scanning Tunneling Microscopy, Sacharia Albin, Jianli Zheng, John B. Cooper, Weihai Fu, Arnel C. Lavarias

Electrical & Computer Engineering Faculty Publications

Diamond microparticles were grown on etched tungsten wires using a microwave plasma-assisted chemical vapor deposition process. The apexes on cubo-octahedral particles bound by {100} and {111} facets were effectively used as tunneling tips for scanning tunneling microscopy. The atomically resolved surface image of highly oriented pyrolytic graphite was acquired. Tunneling characteristics revealed a higher electron emission from the diamond tips than that from the platinum–iridium tips. The same diamond tips were used to produce surface indentation and its image. © 1997 American Institute of Physics.

Optical And Electrical Properties Of Cualse² Thin Films Obtained By Selenization Of Cu/Al/Cu... Al/Cu Layers Sequentially Deposited, J. C. Bernède, S. Marsillac, C. El Moctar, A. Conan

Electrical & Computer Engineering Faculty Publications

Optical and electrical properties of CuAlSe₂ thin films obtained by selenization of Cu/Al/Cu...Al/Cu layers sequentially deposited have been investigated. It is shown that the expected energy gap (2.67 eV) is measured for well crystallized films, whereas a slightly higher value is measured for films not so well crystallized. Raman diffusion also shows differences between well and poorly crystallized films with peaks corresponding to the reference powder for the former samples. A p-type conductivity is found whatever the crystalline quality of the samples. The conductivity of the films depends also strongly on their crystalline properties. When the films are badly …

Specialized Labor And Employment Law Institutions In New Zealand And The United States, Andrew P. Morriss

Faculty Scholarship

Legal specialization takes several forms: decision-makers and advocates can specialize in particular types of cases, specialized rules can govern particular types of disputes, facts may be found by experts, appeals heard by special courts, or some or all of these combined. The American and New Zealand employment and labor law regimes make different use of specialized decision-makers, in part because of differences in their use of specialized legal rules for labor and employment law. These differences provide an opportunity to assess the appropriateness of specialization in legal decisionmaking.

Specialization in the legal system is simply one form of the more …
