Towards Understanding: The Study Of Hughes' Poetry As The Epitome Of The Expressive, Cultural, And Political Elements Of African American Literature, Brianne Nicole Trudeau

Masters Theses

Unfortunately, a disconnection currently exists between the academic world and the sweet, soulful study of African American literature (AA literature). Because there is limited exposure to AA literature in academics, except for specialized courses in which it serves as the intended focus, most people do not know how to approach it as serious academic study because of its stark differences from Western literature. In sum: African American writers often do not utilize Standard English (SE), so their work is misinterpreted as non-academic in comparison to other Western works of prominence; AA literature tells a different cultural story that most of …

Sediment Remediation Impacts On Macroinvertebrate Community Structure: Assessing The Success Of Urban Stream Restoration, Laurie Beth Nederveld

Masters Theses

Land use practices altering the natural landscape have resulted in the widespread degradation of stream ecosystems and the need for urban stream restorations. While a number of studies have evaluated the success of these stream restoration efforts, few have assessed the recovery of macroinvertebrate communities following the remediation of contaminated sediments. The purpose of my study was to evaluate the impact of sediment remediation activities on macroinvertebate abundance, diversity, and richness to determine the success of stream restoration in Ruddiman Creek, a small stream in the Muskegon Lake watershed. During my investigation, macroinvertebrate samples were collected from all available habitat …

The Proper Candidate: An Examination Of The 1525 Debate Between Ulrich Zwingli And Balthasar Hubmaier Concerning Baptism, Kurt J. Thompson

Masters Theses

This thesis examines the written debate that occurred in 1525-1526 between Balthasar Hubmaier and Ulrich Zwingli on the proper candidate of baptism. Both pastors held to the reformation principle of sola scriptura yet came to different conclusions as to what the Bible teaches about baptism. Hubmaier argued that baptism should be administered to believers only. Only those who have mindfully repented and have chosen to follow Christ are eligible for Christian baptism. Hubmaier's arguments for believers' baptism are presented in the second chapter. Zwingli, on the other hand, argued that the children of believers are entitled to the Christian baptism. …

A Radical Phenomenology Of Love: Divine Love As Understood By The Radically Orthodox John Milbank, Jason Wesley Alvis

Masters Theses

The topic of Divine love is no longer taken seriously. In some sense it is difficult for one to even utter the words "God is love" without an accompanying mawkish sentimentality. One's concept of love in general, and Divine love in particular, is a linchpin to all other theological, ethical and social spheres of life. This thesis considers how John Milbank, the "father" of Radical Orthodoxy, understands Divine love, and some ways in which his work may be positively situated in the Ecclesial Community and lead individuals into deeper experiences of such love. Since Milbank has very few explicit words …

Transcending Tragedy: The Power Of The Green World In Renaissance Drama, Sheridan Lynn Steelman

Masters Theses

Hospitals in the twenty-first century are using healing gardens to help patients heal their minds, bodies, and souls by offering views of lush flora from their rooms and calming pathways for their walks. Recent studies have shown that patients who are able to witness nature’s beauty request less pain medication and report shorter stays. Today’s use of gardens as part of a total wellness package may have found its roots in the work of John Gerard (1597) who was the first to study and catalog over 300 varieties of plants and herbs, many of which had common medicinal uses. Gerard’s …

Modeling Of Wear And Oxidation Behavior Of A Carbon/Carbon Multidisk Clutch, Shankar Nagaraj

Masters Theses

"Carbon/carbon composites are a family of advanced composite materials. They are the most advanced form of carbon and consist of a fiber, based on carbon precursors, embedded in a carbon matrix. They are extensively used in design of sliding contact systems such as clutches and brakes because of their low weight, excellent thermal and mechanical properties, chemical inertness and self lubricating capability. They retain their mechanical strength in inert atmospheres up to 2000° C. However, in oxidizing environments, C/C composites rapidly react with oxygen forming gaseous carbon oxides around 450° C.

In the present study a C/C composite clutch assembly …

Network simulation is performed in order to study a wide range of phenomena occurring during MANET communication. The effectiveness of three reactive routing protocols against different level of mobility is observed under varying network parameter like the network size, number of nodes and network connectivity. The study reveals that the network sparseness or density favors one or the other routing mechanism under varying mobility. Outcome of the simulation also provides a great deal …

Reliability-Based Design With System Reliability And Design Improvement, Gagandeep Singh Saini

Masters Theses

"This thesis focuses on developing a methodology for accurately estimating series system probability of failure. Existing methods for series system based design optimization are not that accurate because they assign reliability to each failure mode; as a result complete system reliability goes down. According to method proposed in this work, the user will assign required system reliability at the start and then optimizer will apportion reliability to every failure mode in order to meet required system reliability level. Detlevson second order upper bounds are used to estimate system probability of failure. Several examples have been shown to verify the results …

Fault Detection And Prediction With Application To Rotating Machinery, Gary R. Halligan

Masters Theses

"In this thesis, the detection and prediction of faults in rotating machinery is undertaken and presented in two papers. In the first paper, Principal Component Analysis (PCA), a well known data-driven dimension reduction technique, is applied to data for normal operation and four fault conditions from a one-half horsepower centrifugal water pump. Fault isolation in this scheme is done by observing the location of the data points in the Principal Component domain, and the time to failure (TTF) is calculated by applying statistical regression on the resulting PC scores. The application of the proposed scheme demonstrated that PCA was able …

Preventing Chemical Product Failure, Kenneth Ombete

Masters Theses

"The purpose of this thesis is to demonstrate a research methodology to prevent chemical product failures. This methodology extends the risk in early design (RED) method for prevention of failure in electromechanical products to include products with chemical subsystems. Inclusion of this domain is demanded by the ever-growing semiconductor and energy industries. The RED method was extended by first identifying principal chemical failure modes and adding them to the failure mode taxonomy. The RED database was then augmented with historical failures of products that included chemical subsystems. Finally, the extension was validated with a case study of a fuel cell"--Abstract, …

Decision-Based Design Under Uncertainty With Intervals, Sashank Vasireddy

Masters Theses

"Design requires a series of decisions, and one of the major challenges engineering designers face is making decisions under uncertainty. The engineering designer must choose the best design among various alternatives. This work evaluates the use of utility functions to make decisions under uncertainty with both random and interval variables. Uncertainty cannot be eliminated completely, but it can be reduced. Most current methods treat only aleatory uncertainty. Here, however, both aleatory and epistemic uncertainties are addressed in the context of engineering design. Methods such as moment matching method and worst case analysis are used to incorporate uncertainty into design problems"--Abstract, …

Anchorage And Bond Characteristics Of Externally Bonded Frp Laminates Used For Shear Strengthening Of Rc And Pc Girders, Carlos Andres Ortega Ordonez

Masters Theses

"In the last three decades, the use of fiber reinforced polymer (FRP) materials to strengthen structures externally has emerged as one of the most promising technologies in materials and structural engineering, and these materials have been gaining popularity in the civil engineering community. Externally bonded FRP sheets and laminates have been used successfully to increase flexural and shear capacity. The overall performance of the strengthened system depends heavily on the quality of the bond between the concrete and the FRP laminate. Low bond strength can cause delamination at the fiber-matrix interface and at the FRP laminate-concrete interface. As a result, …

Why We Failed: The Rise Of Islamic Extremism And America’S Failure To Stop It 1979-2003, Brad Michael Negulescu

Masters Theses

This thesis examines the rise of Islamic terrorism from 1979-2003. It begins with how the Soviet-Afghan war during the 1980’s gave birth to a movement of young Islamic radicals that became known as al Qaeda. The paper then discusses how the organization, led by wealthy Saudi financier Osama bin Ladin, became a principle antagonist of the Clinton Administration throughout the 1990’s. Moreover, it goes on to talk about the numerous successful terrorist acts al Qaeda was able to plan and implement around the world during the 1990’s and how the administration attempted to deal them. It also discusses how the …

Codes Of Conduct: Didacticism In The Works Of Maria Edgeworth, Megan Lockard

Masters Theses

To encounter the novels of Maria Edgeworth is to encounter an author who is not always politically correct. She did not write as a feminist to better the world for women. She did not write in the name of equality between nations or classes. She did not write to promote racial tolerance. In fact, based on her treatment of these issues within her novels, Edgeworth could arguably be accused of anti-feminism, imperialism, and racism. Instead, what this late eighteenth-century, early nineteenth-century writer centered her novels around was a rigid set of moral guidelines. Maria Edgeworth used the novel genre as …

The Letters Of Elizabeth I: Rhetoric For Ruling, Anna M. Patton

Masters Theses

This thesis is an investigation of the rhetorical skill of Elizabeth I of England, focusing primarily on her letters. Elizabeth's rhetorical prowess is well documented; scholars have spent ample time dissecting her political speeches as well as her historical significance in literary, political and historical studies. Although her speeches provide a firm foundation from which to examine Elizabeth and her relationships with her people, her letters are even more pertinent when examining those relationships Elizabeth sought to establish during her reign. Elizabeth's politics and relationships are enhanced and developed by her ability to manipulate those around her with her words. …

Translating Anglo-Saxon Poetry: Foreignized Translations Of The Seafarer And The Wanderer, Andrew Timothy Eichel

Masters Theses

Few scholars argue that medieval literature retains the same prestige today it once held as the foundation of almost every school's English literature/language department. One reason for this fall could be the lack of proper integration of newer literary approaches into the field. Why, despite the recent swell in the use of more contemporary schools of theory-Marxism, feminism, and deconstructionism, for example-do many medieval scholars still endorse traditional strategies of historical and empirical analysis? Focusing on the translation methodology of foreignization, I present Ezra Pound's translation of the Anglo-Saxon poem "The Seafarer" and my translation of "The Wanderer." Both serve …

"Freedom In Working": Representations Of Working Women In Elizabeth Gaskell's Mary Barton, Ruth, And North And South, Amy King

Masters Theses

In my M.A. thesis, I explore Elizabeth Gaskell's representations of women workers in her three novels, Mary Barton, Ruth, and North and South through the context of Victorian domestic ideology and social class. I argue that Elizabeth Gaskell supported and challenged the accepted gender roles for women. Through a close reading of her novels and short stories, I analyzed the reasons behind her conflicting and ambiguous portrayals of working women. I argue that while Gaskell clearly advocated domestic work as the "natural" work for women, her views on wage-earning labor varied; however she suggests that women, regardless of class, could …
