An Analysis Of Texture Resulting From Thermomechanical Processing Of Ti-6al-V, David J. Brock Dec 1998

An Analysis Of Texture Resulting From Thermomechanical Processing Of Ti-6al-V, David J. Brock

Masters Theses

An investigation of texture and microstructure formation in Ti-6Al-4V after thermomechanical processing and heat treating was performed. X-ray diffraction was used to measure prismatic and pyramidal pole figures. These pole figures were used to calculate basal pole figures, which showed significant changes in texture from heavy rolling and near or above β-transus heat treatments. Primary texture components were found to be strengthened by near β-transus heat treatments. For heavily rolled material, above β-transus heat treatments were found to reverse the primary texture components order of dominants. Heavy rolling was found to reduce the RD component and strengthen the TD.

Synthesis, Characterization And Photophysical Behavior Of A Cr(Iii) Bimetallic System, Yan Chen

Masters Theses

Many binuclear transition metal complexes have been studied to understand the nature of interactions between the metal centers. People have found Simultaneous Pair Excitation phenomenon in some bimetallic system that can serve as a potential source of Non-Linear Optical behavior.

Thus a series of Cr2 -([14]aneN4)2-X4n+ complexes were synthesized and characterized. Only the cis,cis configuration was found. The results were compared with those of their monomer analogs. The electronic structures are very similar in both monomer and dimer complexes. The quantum yield, UV-Vis absorption and lifetime studies suggested a possible coupling between the …


The Identification Of Domains And Competencies For Community Practice Occupational Therapy, Lisa Anne Werner Dec 1998

The Identification Of Domains And Competencies For Community Practice Occupational Therapy, Lisa Anne Werner

Masters Theses

Literature shows evidence of a shift in occupational therapy from traditional institutional settings to community-based settings. As increasing numbers of new and expert occupational therapists enter community-based practice, the need for competency identification for practice, education, and reimbursement becomes paramount. This qualitative research study sought to identify domains and competencies of community-based occupational therapy practice by interviewing three expert occupational therapists using the critical incident method in which each therapist described one therapeutic intervention with a client. This method, as seen in nursing studies (Benner, 1982, 1984), serves to elicit competencies embedded in expert practice. Thirty-nine competencies were described in …


French Influences On The Historical And Nationalist Thought Of Nicolae Balcescu: An Inquiry Into The Structure Of Romanian Nationalism, Ion Matei Costinescu Dec 1998

French Influences On The Historical And Nationalist Thought Of Nicolae Balcescu: An Inquiry Into The Structure Of Romanian Nationalism, Ion Matei Costinescu

Masters Theses

In the past decade nationalism has been conceptualized as a cultural artifact, a product of invention and social engineering. Yet despite the flourishing interest in questions of national identity, we still have no theory explaining the reasons why nationalism presents itself in a manifold diversity of forms and aspirations. One way of . accounting for the malleability of modern nationalism is to approach it as a product of dialectical interactions between various national ideals. In this respect, the case of Romanian nationalism is particularly instructive. Its nineteenth-century proponents consciously borrowed and adapted French cultural mores and ideological forms since they …


The Origins Of Greek Cypriot National Identity, Elena Koumna Dec 1998

The Origins Of Greek Cypriot National Identity, Elena Koumna

Masters Theses

Discussions of Greek Cypriot identity have conventionally been dominated by primordial arguments, contributing to the creation and maintenance of stereotypes and mythologies about the ethnic conflict between Greek and Turkish Cypriots. In order to examine the validity of the primordial thesis, modernist and constructionist approaches on nationalism and identity are considered (Gellner 1983; Hobsbawm 1990; Anderson 1991; Hroch 1985; Smith 1991). Nationalism and identity formation are analyzed in the context of"stages," where the social composition of each stage and the degree of modernization are examined. The findings of the thesis largely support the hypotheses that pinpoint the articulation of Greek …


Adaptive Channel Equalization Techniques, Saied Razavilar Dec 1998

Adaptive Channel Equalization Techniques, Saied Razavilar

Masters Theses

Inter Symbol Interference (ISI) is a characteristic of band-limited communication channels that can severely degrade the digital communication system performance if not treated properly. Channel equalization techniques may be used to mitigate the effects of ISI in the system, thereby improving the system capacity and performance. In this thesis, the problem of Inter Symbol Interference caused by the nonlinear characteristics of band limited communication channels and adaptive equalization techniques to combat the effects of ISI are discussed. First, the analysis of ISI in a band limited communication channel using a concrete theoretical framework is presented. Next, various adaptive equalization techniques …


Re-Cycling The Menstrual Cycle: A Multidisciplinary Reinterpretation Of Menstruation, Heather H. Rea Dec 1998

Re-Cycling The Menstrual Cycle: A Multidisciplinary Reinterpretation Of Menstruation, Heather H. Rea

Masters Theses

This thesis offers a reinterpretation of the human female menstrual cycle that understands the process as positive, functional, and practical experience. Standard western definitions and understandings of menstruation use negative terminology and focus on menstrual blood as an indicator of failed conception. This view contributes significantly to the negative perception women have of menstruation in general, their own menstrual cycles, and ultimately of their femaleness. This fundamental, physiological process that symbolizes femaleness, the menstrual cycle, has been defined both, bio-medically and culturally, as a negative experience. I propose a reconceptualization of the menstrual cycle that is not only a tool …


A Portable, Object-Oriented Library For Neural Network Simulation, Martin P. Franz Dec 1998

A Portable, Object-Oriented Library For Neural Network Simulation, Martin P. Franz

Masters Theses

A portable, object-oriented library for simulation of general Multi-layer Feedforward Neural Networks (MLFNs) is described. Unlike all-encompassing neural network simulation environments, the library was designed to allow convenient use in existing programs and in applications where training and testing data are generated using separate, often complex simulations.

The library' s design goals include modularity, portability, efficiency, correctness, compactness, and type-safety. To demonstrate how these objectives are met, competing architectural choices are presented, along with the criteria used for determining the strategy actually implemented. Sample applications using the library are presented, showing how the library' s class files are used in …


Spatial And Temporal Variations Of Cloud-To-Ground Lightning In Southern Michigan, Michael A. Crimmins Dec 1998

Spatial And Temporal Variations Of Cloud-To-Ground Lightning In Southern Michigan, Michael A. Crimmins

Masters Theses

Lightning has a profound impact on many aspects of modern day society. Understanding its temporal and spatial distributions is fundamental in learning to coexist with its destructive power. This study surveyed the spatial and temporal distribution of cloud-to-ground lightning over southern Michigan using data provided by the Detroit Edison Company. Flash density and 'lightning day' maps were produced for every year of the 1985 to 1995 study period and then averaged to determine long term trends. A temporal analysis determined the distribution of lightning from the inter-annual down to the diurnal scale.

The spatial analysis indicates both deficiencies in the …

Mathematical Model Of Paper Discoloration By Ink Particles, Zbigniew W. Slotwinski Dec 1998

Mathematical Model Of Paper Discoloration By Ink Particles, Zbigniew W. Slotwinski

Masters Theses

The goal of this experiment is to investigate how changes in the size and number of ink particles will affect the final brightness of the filter pad.

It was assumed that any differences in brightness of the used Millipore filters were due to change in the average particle size, given the same mass of ink solids on each filter. However, such simplified interpretation of image analysis proved to be inadequate to solve this complex problem.

The correlation between the particle area, number of particles, and brightness drop was established using an algorithm based on the particle area and the square …


Nickel Subsulfide Can Protect Human Fibroblasts From The Mutagenic Effect Of Benzo[A]Pyrene Diolepoxide, Samir M. Hamdan Dec 1998

Nickel Subsulfide Can Protect Human Fibroblasts From The Mutagenic Effect Of Benzo[A]Pyrene Diolepoxide, Samir M. Hamdan

Masters Theses

Cancer researchers are interested in identifying the environmental causes and synergistic influences of different carcinogens. It is important to examine the combined effect of multiple carcinogens since this is a more realistic representation of the true environmental situation in which we are exposed daily. Our study has reported that pretreating human fibroblasts with nickel subsulfide followed by the simultaneous treatment with both nickel subsulfide and benzo[a]pyrene diolepoxide (BPDE) can protect human fibroblasts from the mutagenic effects of BPDE. These results correlate well with our previous chromium-BPDE co-treatment work, suggesting a transition metal dependent protective effect. This protective effect was dependent …

Fitness Landscape Analysis Of Discrete Constrained Optimization Problems, Sai Prasanna Ravichandran Dec 1998

Fitness Landscape Analysis Of Discrete Constrained Optimization Problems, Sai Prasanna Ravichandran

Masters Theses

The exponentially large size of the solution space of typical optimization problems precludes the use of any deterministic approach to search for an optimal solution. A more efficient and efficacious approach is to use heuristic algorithms based on rules of thumb to guide the search process in the solution space. Associated with every solution in the space is a real number called fitness that signifies the quality of a solution. This space and the fitness values together form the fitness landscapes. Knowledge about the topology of these fitness landscapes is vital for any heuristic search operator to expedite the search …

The Impact Of Women' S Traditional Caregiving Roles On Their Paid Labor Force Participation Throughout Their Lifecourse, Paulina X. Ruf

Dissertations

Since women are the majority of caregivers to older and/or disabled relatives, the increasing number of women in the labor force has meant that more caregivers are also employed. In an effort to expand our understanding of the perils and benefits of women's caregiving roles, the present study examines the impact of women's traditional caregiving roles on their paid labor force participation throughout their lives. This qualitative study involved semistructured, in-depth interviews with sixteen women (i.e., six in their 50s, four in their 60s, and six women in their 70s), to answer the question, "how do family caregiving roles cumulatively …

Black Women Build Community: An Examination Of The Radcliffe Black Women Oral History Project, Dawn Michelle Hinton

Dissertations

This study investigated the unique position of Black women in the creation of community. Narratives from the Radcliffe Black Women Oral History Project were the source of information used for this work. These 20 oral narratives were collected between 1978 and 1982 by the Schlesinger Library. The women studied were involved in various community activities and represent Black women from various social classes and geographical locations. An in-depth reading of each of the narratives identified three themes: life-informing work, community-building, and religion. The theme of life-informing work was identified because the work and community involvement of the narrators had a …


Loss Of The Lifelong Partner: Implications For Social Adaptation, Anora Ackerson Grinwis Dec 1998

Loss Of The Lifelong Partner: Implications For Social Adaptation, Anora Ackerson Grinwis

Dissertations

The death of a partner has long been recognized for its ability to alter the lifestyle of the survivor. This life event can be even more significant for older adults who may be facing loss in several areas of their lives simultaneously. The focus of this qualitative study is on how older adults socially reconstruct their lives following a partner's death. The social construction of reality (Berger and Luckmann, 1966) guides design and analysis. Semistructured interviews were conducted with 29 individuals following the death of a lifelong partner, described as a relationship of 45 or more years. Participants had been …

Temporary Employment: The Spanish Experience, Catalina Amuedo-Dorantes Dec 1998

Temporary Employment: The Spanish Experience, Catalina Amuedo-Dorantes

Dissertations

In an effort to promote employment flexibility and reduce the unemployment rate, Spanish authorities deregulated temporary employment in the early 1980s. Nonetheless, the deregulation of temporary employment took place at the margin, favoring the development of a dual labor market in which temporary workers constituted a second class of workers involuntarily employed and enduring limited advancement opportunities.

Using data from the Spanish labor force survey, Spanish temporary employment and job transitions into and out of temporary employment are examined. The study first evaluates the incidence of Spanish temporary employment and its involuntary and demand-led character. Secondly, the analysis reveals temporary …

Max Horkheimer’S Critical Theory Of Religion:The Meaning Of Religion In The Struggle For Human Emancipation, Michael R. Ott Dec 1998

Max Horkheimer’S Critical Theory Of Religion:The Meaning Of Religion In The Struggle For Human Emancipation, Michael R. Ott

Dissertations

Over the past thirty years much has been written about the critical theory of society that was produced by a small group of left-wing Hegelians in the Institute of Social Research in Frankfurt am Main, Germany and in the United States. However, except for the pioneering work of Rudolf Siebert, little has been written about the critical theory of religion as a fundamental and dynamic element of the entire critical theory’s struggle for human emancipation. This study seeks to make a contribution in the development of the critical theory of religion as a corrective to the one-sided, positivistic development of …
