Multistage Random Key Genetic Algortihm Optimization For Scheduling Flexible Flow Lines With Sequence Depenedent Setup Times, Aadithan Anbuvanan

All Theses

This thesis proposes a new variation to the Random Key Genetic Algorithm (RKGA) for scheduling optimization in flexible flow line manufacturing with sequence dependent setup times. The proposed RKGA representation decodes scheduling information independently at each stage, unlike the traditional RKGA, which is only sequenced based on the first stage, limiting flexibility. The proposed method's performance is compared to the traditional method with varying numbers of jobs and stages. It is compared regarding performance ratio and statistical significance of differences through the Wilcoxon Signed Rank Test. Results show that the proposed RKGA outperformed traditional RKGA in high complexity (8 Stage …

Interobserver Agreement Of Human Osteological Analysis On The Szeged, Hungary Skeletal Collection, Alleyia Bailey

All Theses

Biological anthropologists develop human skeletal biological profiles to identify skeletal remains and build demographic knowledge of past and modern peoples. Biological anthropologists estimate age-at-death, sex, stature, ancestry, and the presence of injury or pathology to develop biological profiles. While biological profiles are at the basis of the work anthropologists perform, there is a lack of research concerning the reproducibility and interobserver agreement rates of the methods used to create biological profiles. Due to the risk of variability stemming from the education, training, and experience of observers, along with variation that can arise from population affinity, examining the interobserver agreement rates …

Reinforcement Learning For High-Dimensional Tradespace Exploration In Multi-Objective Optimization, Aaditya Kothavade

All Theses

Engineering design optimization often requires balancing multiple competing objectives while navigating complex, high-dimensional tradespaces. Despite significant advances in tradespace exploration techniques, current methods face critical challenges in efficiently navigating high-dimensional design spaces. As the number of design variables and competing objectives increases, traditional multi-criteria decision-making and optimization methods struggle to explore the vast solution space comprehensively. The curse of dimensionality exacerbates this issue, making it impractical to analyze all possible solutions and effectively identify trade-offs between objectives. Additionally, the computational complexity of high-dimensional spaces further complicates optimization, making exhaustive solution analysis infeasible. Traditional multi-objective optimization methods rely on static Pareto-front …

Rhetorics Of Motherhood In Fiction:Motherhood As Identity And Status-Quo, Brea A. Hudson

All Theses

Motherhood has become a highly politicized and dominant topic in public discourse, with it often being a beacon of good-will and the building block of feminine identity. Lindal Buchanan’s Rhetorics of Motherhood demonstrates how motherhood has been used by all types of political ideologies to make women more palpable in public spaces. Miranda July’s All Fours explores an identity shift in an aging mother. In my collection, I explore these different identities and facets of motherhood and what that looks like for characters who struggle with infertility, loss, and addiction. My collection shows motherhood in a realistic and messy view …

Race, Sex Work, And Spatial Segregation In Storyville, New Orleans, Paige M. Magoto

All Theses

Storyville, New Orleans, operated as a legalized vice district from 1897 to 1917. This 38-block area facilitated sex work and prostitution “across the color line,” perpetuating and encouraging the practice of white men seeking sexual acts from Black women and women of mixed-race descent. I engage with multiple interacting subsections of historiography within this thesis project. The historiography spans Southern history from the early nineteenth century in the Old Antebellum South until the early twentieth century in the Progressive Era. The broader historiographic dimensions of labor and sexuality were also influential in curating this research project, engaging with the evolving …

The demolition of historically undervalued vernacular architecture for the construction of transportation projects has created a large-scale, cumulative loss of architectural heritage nationwide. This thesis quantifies the architectural loss caused by the construction of the series of Cooper River bridges in peninsular Charleston and Mount Pleasant. This study assesses the transformation of the built environment as a result of each bridge’s construction by determining the quantity of architectural loss, identifying forms and materials of architectural loss, and differentiating the effects of bridge construction on the more rural Mount Pleasant side compared to the urban peninsular Charleston side. Also assessed in …

Speaking Up: A Courage Framework Of Bipoc Voices In The Workplace, Aishah Khan

All Theses

Despite the many beneficial outcomes of voice in the workplace, employers and employees do not often utilize it to its full potential, particularly those from historically marginalized groups. Past literature has examined the many ways in which the experience of minority-group members differs from that of majority-group members; however, scarce work has been done exploring the “mental calculus” that those from marginalized groups go through when deciding whether to advocate for themselves or others at work. To provide insight into this specific experience, I manipulated representation and context in a novel fashion – and examined if and how safety, risk, …

A Qualitative Analysis Of Graffiti Inscriptions At Ecclesiastical Sites In The South Carolina Lowcountry, Hannah Truman

All Theses

The study of graffiti has become a multi-disciplinary study. Historical and modern forms of graffiti offer a unique perspective on the connection people have with religious sites over the span of three hundred years. Within South Carolina, the establishment of twenty-five churches throughout the Lowcountry from 1706 to 1775 offers an understanding of people’s connection to spaces from the beginning of South Carolina’s establishment to the present day. Their beliefs are reflected throughout the space of the building as congregations have left their imprint.

In order to understand the relationship of people to the site over time, various methods were …

Thymosin Beta-4: A Novel Treatment For Acanthamoeba Keratitis, Victoria A. Murphey

All Theses

Acanthamoeba keratitis (AK) is a severe corneal infection caused by the free-living amoeba, Acanthamoeba. Both stages of its life cycle (trophozoite and cyst) cause infection, primarily in contact lens wearers. It is often misdiagnosed, leading to delayed treatment and poor clinical outcomes. Current treatment options for AK rely on anti-amoebic agents that are toxic to corneal epithelial cells. Further, no single drug can eliminate both forms of the amoeba. Approximately 30% of all AK infections require a corneal transplant.

Thymosin beta-4 (Tβ4) is a G-actin binding protein synthesized in almost all human cells, including corneal epithelial cells. Tβ4 exhibits …

African Sleeping Sickness: From Basic Biology To Future Directions, Riddhi R. Patel

All Theses

African Sleeping Sickness is a Neglected Tropical Disease (NTD) which poses a significant health risk to impoverished populations in 36 Sub-Saharan African countries. It is a devastating disease caused by the protozoan parasite Trypanosoma brucei, which is transmitted to mammals via the bite of infected tsetse flies. The disease manifests in two stages: the hemolymphatic stage and the meningoencephalitic stage. In the latter stage, it invades the Central Nervous System (CNS) and can be fatal if left untreated. It is caused by morphologically indistinguishable species of Trypanosoma brucei in both humans and animals, where in humans it is known as …

Evaluating The Role Of Electrostatic Forces In The Adsorption Of Perfluoroalkyl Substances To Granular Activated Carbon, Thomas A. Mccall

All Theses

In response to new drinking water regulations announced by the EPA in 2024, many municipalities will need to monitor concentrations and implement new treatments to address PFAS, a class of anthropogenic organic contaminants. A leading technology for this application is GAC adsorption due to its familiarity and availability. The adsorption of four PFAS species (PFBA, PFBS, PFOA and PFOS) to Calgon Filtrasorb400 (F400) was evaluated for a range of pH and ionic strength conditions to investigate the role of electrostatic interactions in adsorption capacity. These PFAS are all strong acids, so pH was used as a control for GAC surface …

Graph Based Deep Reinforcement Learning Aided By Transformers For Multi-Agent Cooperation, Michael S. Elrod

All Theses

Mission planning for a fleet of cooperative autonomous drones in applications that involve serving distributed target points, such as disaster response, environmental monitoring, and surveil- lance, is challenging, especially under partial observability, limited communication range, and uncertain environments. Traditional path-planning algorithms struggle in these scenarios, particu- larly when prior information is not available. To address these challenges, I propose an innovative framework that integrates Graph Neural Networks (GNNs), Deep Reinforcement Learning (DRL), and transformer-based mechanisms for enhanced multi-agent coordination and collective task ex- ecution. My approach leverages GNNs to model agent-agent and agent-goal interactions through adaptive graph construction, enabling efficient …

Blockchain-Integrated Version Control For Secure And Transparent Software Supply Chains, Iwinosa W. Aideyan

All Theses

The software supply chain encompasses all stages of software development and delivery from initial coding and version control to integration and deployment. As development environments become increasingly distributed and reliant on external dependencies, ensuring the integrity, auditability, and consistency of code changes has become a pressing challenge. Traditional version control systems like Git, while effective for collaboration and tracking revisions, do not inherently provide tamper-evident commit histories. Features such as history rewriting (e.g., git rebase, git push --force) can be exploited to manipulate commit logs without detection, posing risks in security-sensitive domains. This thesis proposes a blockchain-integrated version control framework …

Unsettling Femininity In Ottessa Moshfegh’S My Year Of Rest And Relaxation, Audrianna Witcher

All Theses

This thesis covers how Ottessa Moshfegh’s My Year of Rest and Relaxation critiques traditional understandings of femininity and the inadequacy of neoliberal feminism to address the systemic issues that women face. Using Lauren Berlant’s concept of femininity as a genre, this thesis traces how Moshfegh implements disgust and abjection to reject mandates of cleanliness and emotional labor that are central to traditional femininity. Moshfegh also utilizes disgust and the narrator’s attempt at a year-long sleep to resist the ideals of productivity and self-care that are central to neoliberal feminism. In employing these affects, Moshfegh resists the social structures that exploit …

“Raise Your Keffiyeh:” Headdress As A Lens For Understanding The Arab Revolt In Mandatory Palestine, 1936-1939, Kathryn Kf Butler

All Theses

In the fall of 1938, approaching the apex of the most intensive period of violence during the Arab Revolt against the British government in Mandatory Palestine (1936-1939), a seemingly unassuming change occurred for Arab men in cities throughout the region: they donned a new headdress. Sartorial shifts in the early post-Ottoman period were not unique to Palestine. During the Interwar period, changes in male headgear occurred throughout the greater Middle East in Turkey, Afghanistan, Iran, Syria and Iraq, to name a few. These transformations of dress signaled a shift in something either societal or political and oftentimes both. I argue …

"All The Songs I Stole": Ballad Collection And The Conditions Of Collective-Making In Johnny Cash's Prison Concert-Albums, Camryn J. Bruce

All Theses

In the mid-to-late twentieth century, singer-songwriter Johnny Cash recorded and released three live prison concert-albums composed of many ballads and songs drawing upon a ballad tradition. I question the degree to which these albums, as performed and commercialized ballad collections, create realities of unity between Cash and his audiences. Reviewing three ballads for their aspects of balladry and performance, this thesis finds that Cash’s albums echo and make echoes of isolating conditions and possible collectivities, demonstrating a fragility of “folk” in the shifting scenes of music and prison.

Using qualitative data gathered from two focus groups of millennial participants, this study reveals that millennials represent a diverse and distinct audience with unique expectations for nonprofit communication. Grounded in public relations theories of stewardship and organization-public relationships (OPR), the research highlights the importance of flexibility and autonomy …

Defining Fidelity For Tradespace Application, Aditya Agrawal

All Theses

This research proposes a definition of tradespace fidelity and presents a study on its effectiveness in the tradespace. Tradespace exploration helps evaluate various design options, allowing engineers to make informed decisions in early design stages. Fidelity generally refers to how closely a model approximates reality. However, the definition of fidelity has been inconsistently defined and interpreted in various contexts concerning particular problems. In some cases, it is a measure of accuracy; in others, information; in another, uncertainty; and in others, computational complexity. Fidelity is poorly and inconsistently defined in the literature. In general, higher fidelity models tend to be more …

Investigating Psychological Moderators Of The Effect Of A Slow-Paced Breathing Intervention On Decision-Making Performance, Anthony Alvarado

All Theses

Decision-making is a ubiquitous cognitive process that individuals engage in constantly—some decisions are inconsequential while others can have drastic implications. Identifying ways to improve decision-making, therefore, has potential to have lasting positive effects. One potential approach is slow-paced breathing interventions. While such interventions have shown promise for improving certain aspects of cognition, such as working memory, few studies have examined the effect of slow-paced breathing on decision-making performance. The current study sought to examine the effect of a brief slow-paced breathing intervention on performance on the Iowa Gambling Task (IGT), a reward-based decision-making task. Potential moderating variables such as stress, …

Divergence-Free Smoothed Particle Hydrodynamics In A Stream Digital Twin, Austin Hartley

All Theses

Digital Twins (DT) are being explored by the South Carolina (SC) water community to simulate how SC streams will flow at various water levels. Currently, a DT called Gilligan simulates these streams utilizing weakly-incompressible Smoothed Particle Hydrodynamics (SPH). This method does not strictly enforce incompressibility, which leads to unrealistic water flows and unwanted visual artifacts that require post-processing effects to hide. To address these problems and simulate more realistic water flows, the Gilligan stream logic is updated and a state-of-the-art SPH method that enforces incompressibility—Divergence-Free SPH (DFSPH)—is implemented within the Gilligan framework. DFSPH is able to make use of two …
