East Of The Tracks: Grassroots Environmentalism In South Mississippi, Heather Kay Sanchez

Master's Theses

Environmental justice literature challenges the disparity and oppression regarding the quality of life associated with residential environments among communities of color. Recent disasters, such as hurricane Katrina, the Tennessee coal sludge disaster (December 2008), and the BP Oil Spill (2010) have garnered visibility for environmental issues, particularly in the south. Nevertheless, the topic has largely been ignored in Mississippi among academia, many advocacy groups, and at the state level despite the emergence of several community based grassroots environmental groups throughout Mississippi in recent years. From Columbia, to Crystal Springs, to Hattiesburg, a coalition of environmental groups is forming with Hattiesburg …

"Where The Deepening Thunders Call": Voice In Herman Melville's Battle-Pieces And Aspects Of The War, Loren Percy Bishop

Master's Theses

Scholarship has long under-appreciated Herman Melville's 1866 collection of Civil War poetry, Battle-Pieces and Aspects of the War, partly due to the poems' inconsistent and distanced perspectives. Melville's experimental use of poetic voice and his unconventional depiction of fictional voices within the poems contribute to the collection's distanced perspectives, as well as to the volume's sometimes difficult and even awkward poetics. However, these experimental voices are also crucial to understanding Melville's attempt to describe changes in the relationship between American individuals and the nation occurring during and immediately following the tumultuous war. Melville's experiments in poetic voice also denote …

Capecitabine Induced Hand And Foot Syndrome And The Reproducibility Of Friction Skin, Rodney Allen Schenk

Master's Theses

In 2008, a 62 year old male was detained by United States Customs and Immigration officials when attempting to enter the United States because his fingerprints were not detectable. It was later reported by his medical doctor in Singapore that the individual suffered from Hand and Foot Syndrome (palmar-plantar erythrodysaesthesia) as a result of his cancer treatment of capecitabine (N4-pentyloxycarbonyl-5-deoxy-5- fluorocytidine) which causes interruptions to the normal growth of keratinocytes in the friction skin. Capecitabine is a recently developed, orally administered fluoropyrimidine prodrug designed to generate 5-fluorouracil through a three-step enzymatic process giving it antineoplastic properties to combat cancerous tumor …

Techniques To Characterize Vapor Cell Performance For A Nuclear-Magnetic-Resonance Gyroscope, James Julian Mirijanian

Master's Theses

Research was performed to improve the procedures for testing performance parameters of vapor cells for a nuclear-magnetic-resonance gyroscope. In addition to summarizing the theoretical infrastructure of the technology, this research resulted in the development and successful implementation of new techniques to characterize gyro cell performance.

One of the most important parameters to measure for gyro performance is the longitudinal spin lifetime of polarized xenon atoms in the vapor cell. The newly implemented technique for measuring these lifetimes matches results from the industry standard method to within 3.5% error while reducing the average testing time by 76% and increasing data resolution …

Autonomous Tracking And Following Of Sharks With An Autonomous Underwater Vehicle, Esfandiar Manii

Master's Theses

This thesis presents the integration of an acoustic tracking system within an autonomous underwater AUV (AUV) to enable real-time tracking of sharks tagged with artificial acoustic sources. The tracking system consists of two hydrophones and a receiver unit that outputs a measurement of the relative angle to the tagged shark. Since only two hydrophones are used, the sign of the relative angle measurement is unknown. To overcome this ambiguity, a particle filter algorithm was developed to estimate the position of the acoustic source. When combined with an active control system that drives vehicle to obtain different orientations with respect to …

William Colmer And The Politics Of The New Deal Labor Legislation 1933-1940, Zachary Wyatt Moulds

Master's Theses

William (Bill) Colmer first entered Congress in 1933, the same year that President Franklin D. Roosevelt and his New Deal began to reshape the role of government in the United States. While the New Deal's efforts to combat the Great Depression proved popular in the beginning, by 1935 many congressmen, especially southerners, began to distance themselves from the administration's attempts at social reform. Although many of his colleagues refused to endorse the increasingly liberal agenda of the New Deal, Congressman Colmer remained loyal throughout the decade. His loyalty to the administration was due in part to the south Mississippi district …

Multi-Circle Detections For An Automatic Medical Diagnosis System, Dingran Lu

Master's Theses

Real-time multi-circle detection has been a challenging problem in the field of biomedical image processing, due to the variable sizes and non-ideal shapes of cells in microscopic images. In this study, two new multi-circle detection algorithms are developed to facilitate an automatic bladder cancer diagnosis system: one is a modified circular Hough Transform algorithm integrated with edge gradient information; and the other one is a stochastic search approach based on real valued artificial immune systems. Computer simulation results show both algorithms outperform traditional methods such as the Hough Transform and the geometric feature based method, in terms of both precision …

The Impact Of Increased Collateral Flow On Transverse Arteriolar Microvascular Tree Morphology, David Danzeiser

Master's Theses

The goal of this study was to understand how arteriogenesis impacts transverse arteriolar tree structure. The previous process involved a vascular casting technique that utilized black India ink as the casting agent and manual measurement of vessel morphology with ImageJ. This study decreased the complexity of the casted samples by using a casting compound called Microfil. Microfil’s viscosity can be adjusted and through experimentation, a viscosity was found that stopped at the capillary level, allowing only the arterial side of the circulation to be casted. A macro in ImageJ was written to help with morphological measurement by bundling vessel length …

Combustion Simulations Using Graphic Processing Units, Mingjie Wang

Master's Theses

Graphic processing units (GPUs) are powerful graphics engines featuring high levels of parallelism and extreme memory bandwidth, which constitute a powerful computing platform to solve complex problems involving chemically reacting flows. In the present study, computer programs for combustion simulations with detailed chemical kinetic mechanisms were compiled in the Compute Unified Device Architecture (CUDA) language for NVIDIA GPU architecture. Ignition processes were simulated under constant pressure and constant volume conditions using an explicit 4^th order Runge-Kutta algorithm for time integration. Sufficiently small time steps were identified with time scale analysis to ensure the integration stability. The program was validated …

An Interactive Visualization Model For Analyzing Data Storage System Workloads, Steven Charubhat Pungdumri

Master's Theses

The performance of hard disks has become increasingly important as the volume of data storage increases. At the bottom level of large-scale storage networks is the hard disk. Despite the importance of hard drives in a storage network, it is often difficult to analyze the performance of hard disks due to the sheer size of the datasets seen by hard disks. Additionally, hard drive workloads can have several multi-dimensional characteristics, such as access time, queue depth and block-address space. The result is that hard drive workloads are extremely diverse and large, making extracting meaningful information from hard drive workloads very …

Agency, Structures And Peru: Action And In-Action During 1980-2000, Kimberly A. Protzel

Master's Theses

The Shining Path along with Alberto Fujimori's presidency in Peru (encompassing the years 1980-2000) created a terrifying chaos that was wound up in both state and insurgent terrorism, corruption, and massacres. While this chaos is inextricably linked to Peru's history, I fear is being all too quickly forgotten. My main motivation behind this research has been to take a step towards increasing awareness of these events and the many reasons behind them: the agenic nature of some versus the lack of it in others, structures developed by colonialism, and most terrifyingly of all - willful ignorance. By understanding these reasons, …

Testing is an integral part of a satellite’s development, requirements verification and risk mitigation efforts. A robust test program serves to verify construction, integration and assembly workmanship, ensures component, subsystem and system level functionality and reduces risk of mission or capability loss on orbit.

The objective of this thesis was to develop a detailed test program for pico-satellites with a focus on the Cal Poly CubeSat architecture. The test program established a testing baseline from which other programs or users could tailor to meet their needs. Inclusive of the test program was a detailed decomposition of discrete and derived test …

Polar Field Oriented Control With 3rd Harmonic Injection, Martin Todd Hess

Master's Theses

Abstract

POLAR FIELD-ORIENTED CONTROL

with

3^RD HARMONIC INJECTION

Martin Todd Hess

Field Oriented Control (FOC), also known as vector control, is a widely used and well documented method for controlling Permanent-Magnet Synchronous Motors (PMSM) and induction motors. Almost invariably the orientation of the stator and rotor (field) fluxes are described in rectangular coordinates. In this thesis we explore the practicality of using polar coordinates.

Third harmonic injection is also a well-known technique that allows full utilization of the bus (DC-link), thus allowing the motor to run to full base speed without the use of field weakening. This technique potentially …

Experimental Investigation Of Suction Slot Geometry On A Goldschmied Propulsor, Nicole M. Thomason

Master's Theses

The Goldschmied Propulsor concept combines boundary layer suction and boundary layer ingestion to improve propulsive efficiency and reduce drag on an axisymmetric body. This investigation of a Goldschmied Propulsor aimed to determine influential characteristics of the suction slot geometry to aid in better slot geometry design and to decrease the suction flow requirements for maintaining attached flow over the entire model surface. The Propulsor model was 38.5 inches in length with a max diameter of 13.5 inches. Three suction slot geometries were investigated with the addition of aluminum cusps to the slot entrance. The cusps varied in the distance they …

Dynamic Model Creation And Scripting Support In The Horizon Simulation Framework, Brian Jeffrey Butler

Master's Theses

Dynamic model creation and support for the Lua scripting language was added to the Horizon Simulation Framework used for the verification and validation of system-level requirements. The addition of scripting support allows for subsystem models and their algorithms to be defined using a simpler scripting language, rather than C++. The Luabind library by Rasterbind software is used to expose the C++ algorithms and classes to Lua that are already defined in the framework. Interoperability between Lua and C++ code allows for the ease of use of a scripting language while utilizing the utility classes and functions already created. The dynamic …

Second Generation Data-Logging System For Long-Duration Field Measurement Of Vibration Exposure And Grip Force, Robert H. Knapp Iii

Master's Theses

Millions of United States workers are exposed to vibration at their job, whether it is from a power tool that causes hand and arm vibration or from heavy machinery. These vibrations are known to result in physical disorders such as Hand-Arm Vibration Syndrome, which can be debilitating to the point where workers can no longer do their job effectively. Research groups have taken an interest in finding what vibration characteristics are most harmful and choose to record vibration information using data-logging devices. Often, many devices, whether they are commercial or custom-built devices, use frequency weightings and full day estimations to …

An Exploratory Investigation Into The Use Of Eaup As An Alternative To Text-Based Passwords, Joseph Ahor Abandoh-Sam

Master's Theses

Security is one of the major concerns of every industry in the world today. One of the best ways of hacking into a computer system is brute forcing. And with the increase in computing, brute forcing has become faster and easy to do. Text-based passwords are still the most popular and most commonly used form of authentication even though the requirements for a good password are still increasing. Research has shown that the best text-based passwords are the random ones that have no sequence or pattern to them. But this also makes it difficult to remember. Well- documented research has …

An Introduction To A Meta-Meta-Search Engine, Martin Lalnunsanga

Master's Theses

Imagine that all the information in the entire world written in every known language, and every graphic image, video clip, or photograph copied digitally was available at your fingertips. This vast amount of data could then be reduced to digital data packets and stored in miniscule form on computer hard drives that are all connected by several other centrally located larger machines, called servers. However, searching for data in a vast system of inter-connected computers is virtually impossible using human faculties and is a far more intricate process than perusing book titles using the library's Dewey Decimal System. In order …

Nonnatives' Perceptions Of Group Work: A Study Of Their Attitudes And Experiences In The Group Work Setting, Ellen Nogueira Rodrigues

Master's Theses

Problem. Studies on group work in the field of second language learning have pointed out positive outcomes of this classroom instruction for providing output and input opportunities for language production, for negotiations of meaning, and for academic language. Furthermore, social-psychological factors that hinder language development are asserted to be prevented by the use of group work. Even though group work may create an excellent environment for second language acquisition, research has indicated that few opportunities seem to be conceded for second language speakers to take active participation in discussions. In short, it seems that nonnatives’ interactions are hindered due to …

Socially Including A 'Resistant People': Intercultural Education And The Roma In Italy, Mary Cristine Mcsweeney

Master's Theses

As "the situation of the Roma" in Europe has grown increasingly concerning, the European Union (EU) has urged Member States to promote the social inclusion of this diverse population. While the EU has challenged Member States to implement intercultural education, Italy has claimed its own "via Italiana" (or "Italian way") as to how it is going about this process. In an attempt to better understand intercultural education and the role of education in social inclusion projects, this paper aims to address the following questions: What are some of the implications of the intercultural educational initiative currently underway in Italy with …

The Hybrid Laboratory: Informal Spaces For Public-Science Interaction, Whitney Ann Ferrin-Rodriguez

Master's Theses

While growing trends in participatory science and public outreach have made science more accessible to publics, science communities and publics have long interpreted science and laboratories as private domains, perpetuating the idea that science is reserved for "experts" and locations for science are deemed "private." Many studies that examine public-science interaction, however, seldom consider the role of space and place. I argue that material spaces shape public-science interactions. My analysis takes place at an institutionalized informal education platform: a hybrid laboratory: a space used by "expert" astronomers to create new visual knowledge and "lay" publics to actively participate in astronomy. …

From Individual Conscience To Parish Culture: A Study Of Two Catholic Parishes In The Archdiocese Of Chicago, Lucas S. Sharma

Master's Theses

The Roman Catholic Church is unique in having a unified set of institutional teachings across one billion people in the world including sixty million American Catholics. However, previous quantitative and qualitative studies in sociology suggest that Catholics are not unified in their beliefs but are actually quite diverse. Additionally, Baggett (2009) suggests that Catholics form distinct parish cultures on the local level, and that these parishes are the location that a majority of Catholics experience their faith. What is not know, however, is how Catholic parishes form cultures, especially around political issues. This study aims to understand exactly this by …

Determination Of The Molecular Mechanisms Of Hyperglycemia-Induced Changes In Cav3.2 Calcium Channel Properties, Ginny Marie Keeling

Master's Theses

Hyperglycemia can cause altered excitability due to increased CaV3.2 T-type calcium channel function, bestowing diabetics an increased neuropathy risk. The objective of this study was to understand the molecular mechanisms of increased CaV3.2 function during hyperglycemia in vitro, which leads to a 58% increase in current density and increased channel open probability (PO), among other changes. Two major findings are reported in this study:

1) The enzymatic elimination of extracellular N-acetylneuraminic acid (NANA) moieties reversed the increase in current density and the shift in PO, showing that hyper-glycosylation alters channel function in disease.

2) Treatment with GM1 (a ganglioside highly …

Illinois Mental Health Courts: Intra-Group Dynamics In The Courtroom Work Group, Shanti J. Raman

Master's Theses

This study was intended to gain insight into key social psychological constructs in an unexplored work-group context: one premised on true team structure. Exploratory information on intra-group dynamics in Illinois mental health courts addressed levels of trust, communication, coordination, efficacy, and conflict resolution within mental health court teams.

A survey assessed how court group members associate these central variables with their teams. All reported relatively high levels of trust and team efficacy, and solid capacities for communication, coordination, and conflict resolution. No notable differences emerged in these variables relative to length of courts' operation. Team members from multiple disciplines held …

Stirring Up The Fires : John Spencer Bassett, "The Negro Question" Ansd Southern History, Robert Spencer Dicks

Master's Theses

In 1903 John Spencer Bassett, a young history professor at Trinity College, took to his pen to produce, "Stirring up the Fires of Racial Antipathy," a bold article intended to provoke discussion about southern race relations. An intense public backlash followed, nearly costing Bassett his job . The event, known as the "Bassett Affair," made national headlines. Many scholars have referenced the "Bassett Affair" as a triumph for academic freedom or as a part of a larger story about southern dissent. The 1903 controversy, however, was just one episode in the story of this iconoclastic historian. Delving into Bassett's personal …

The Social Worlds Of Tattooing: Divergent Sources Of Expertise, Lorrie Kathleen Riley

Master's Theses

Since its commercialization and rise to popularity in mainstream culture, tattooing has increasingly become a profession that effectively blends medical regulation and artistic expertise. Although a non-traditional profession sociologically, tattooing is in the process of an occupational shift, moving from the realm of deviant, working-class art to a commercialized industry of consumers' artistic identity expression. While in the process of this shift, tattooing currently borders several social worlds, each of which are vying for control over its practice. Specifically, the social worlds of art, medicine, and legislation are currently colliding in the struggle to define and control of the practice …

Family In Context: (Re)Entry Narratives Of Formerly Incarcerated Individuals, Jennifer Elena Cossyleon

Master's Theses

The current study is informed by narrative accounts of 39 released prisoners, who provide day-to-day understandings of how they have experienced and continue to experience community reintegration. This study digs deeper into the intricacies of returning to free society, one that often disenfranchises and labels ex-offenders, and attempts to reveal how released prisoners themselves see family as pertinent in their reentry experiences. Respondents' stories are telling of the resources they draw upon, and in particular how their families are involved in that process. Findings suggest that families at times provide material and emotional support, but may also facilitate drug use …
