Complementary Color Laser Illumination For Perceptual Contrast Enhancement In Structurally Colored Samples, Tomoshree Dash

All Theses

Structural color, a phenomenon arising from nanoscale interaction between light and materials, has the potential to unveil biological, chemical, physical, and mechanical characteristics of the sample. It enables direct visualization of the sample by human users with high spatiotemporal resolution. However, its impact is often constrained by challenges in the perceptual differentiation of subtle color variations. This thesis introduces complementary color laser illumination (C²LI) as an imaging technique that enhances color perception of the Human Visual System (HVS) by accessing the psychophysical non-linearities in chromatic color perception. C²LI offers a platform optimized for the HVS by …

Language barriers between English-speaking supervisors and Spanish-speaking workers create safety risks on U.S. construction jobsites. Hispanic workers face higher injury and fatality rates, with miscommunication being a major contributing factor. Existing translation tools lack the accuracy, cultural context, and jobsite relevance needed for effective safety communication.

In this study a mobile application with construction-specific safety phrases in English and Spanish was designed and field tested. The research included a literature review, phrase collection and validation with industry experts, application development and design with a computer science collaborator, and usability testing with supervisors and workers. Surveys and field trials measured navigation, …

Reproduction And Larval Development Of The Invasive Asian Longhorned Beetle In South Carolina, Lindsey A. Stone

All Theses

The Asian longhorned beetle (Anoplophora glabripennis Motschulsky; ALB) is a major threat to forest health due to the damage done by larval feeding in host trees. In 2020, ALB was discovered in Charleston County, South Carolina, which presents a novel climate for this invasive pest in North America. I investigated the reproductive biology and larval development of ALB to support detection and management efforts. By exposing 19 host trees to mated pairs of adults, I was able to determine rates of oviposition success (55%), egg viability (55%), and early larval survival (56%). On average, females chewed nearly 1 egg …

Process Optimization And Cost Reduction For Cellulose Nanocrystals For Metal Removal From Rendered Fat, Sheikh Abdur Rehman

All Theses

Cellulose nanocrystals (CNCs) coupled with polymers featuring a high density of amine functional groups, such as polyethylenimine (PEI), exhibit significant metal-capturing capabilities. Rendered animal fat has applications in a vast number of industries, with the potential to be used as a feedstock for the biodiesel/renewable diesel industries. Nevertheless, rendered fat samples occasionally contain concentrations of metals/inorganic contaminants above the suitable threshold for use in this application. Thus, a cost-effective solution to remove light metal/inorganic contaminants from rendered fat samples is desirable.

To address this problem, a cellulose nanocrystal coupled with polyethylenimine, i.e., CNC-f-PEI, was developed by previous …

Experimental And Numerical Study On The Influence Of Carbon Fiber Reinforcement On The In-Plane Compressive Properties Of 3d Printed Hexagonal Honeycomb Core Structures, Deon Wallace

All Theses

There is difficulty with numerically replicating the behavior of composite honeycomb core structures numerically due to the trouble of gathering material properties from a hollow structure. Also, complex part geometries and carbon fiber reinforcement strategies can lead to unwanted structural weaknesses and variance in material properties that may not be reflected in numerical analysis when the part is additively manufactured. In this study, edgewise compressive testing is used to characterize the mechanical behavior and performance characteristics of these structures. The experimental results indicate an increase in the Young’s moduli of the honeycomb core structures as carbon fiber concentration increases. However, …

Barriers To Mindfulness Training Among Athletes: A Transtheoretical Approach, Annabelle L. Thomas

All Theses

Mindfulness, originating from ancient Eastern traditions, involves developing intentional, nonjudgmental awareness of the present moment (Kabat-Zinn, 2012). In recent years, mindfulness-based interventions (MBIs) have gained recognition in Western contexts for improving both well-being and athletic performance (Hut et al., 2021). Despite growing evidence for the benefits, many athletes still do not engage in mindfulness training. Common barriers include limited time (Gao et al., 2024), stigma (De Petrillo et al., 2009), lack of structure (Bühlmayer et al., 2017; Weber et al., 2023), and doubts about effectiveness (Augustus & Zizzi, 2022). This study examined these barriers among NCAA Division I and club …

Capillary Imbibition Of Shear-Thinning Xanthan Gum Solutions, Aimee Sayster

All Theses

Capillary rise in confined geometries plays a critical role in numerous natural and industrial processes. While classical models such as the Lucas–Washburn equation accurately describe the dynamics of Newtonian fluids, they fail to capture the complex behavior of shear-thinning, non- Newtonian fluids whose viscosity varies with shear rate. This research investigates the capillary rise dynamics of shear-thinning xanthan gum polymer solutions in capillary tubes. The rheological behavior of each fluid is characterized using the Ellis model, which accounts for shear-thinning effects through three key parameters: zero-shear viscosity μ0, characteristic shear stress τ1/2 and viscosity index α. Experimental data was collected …

Cross-Modal Prompting For Multi-Class Visual Anomaly Localization, Duncan F. Mccain

All Theses

Visual anomaly detection is a technology that uses computer vision to automatically identify defects or irregularities in images, such as cracks, scratches, or discolorations on manufactured products. Unsupervised visual anomaly detection does this without needing examples of those defects during the training process. This "unsupervised" approach is crucial in industries like manufacturing, automotive, electronics, and pharmaceuticals, where ensuring product quality is essential for safety, reliability, and cost efficiency. For instance, it helps spot flaws in circuit boards, fabrics, or medical pills during production lines, preventing faulty items from reaching consumers. By reducing manual inspections, it saves time and resources, benefiting …

Study On The Knock Resistance Offered By Thermally Stratifying Water Injections In A Single Cylinder Spark Ignition Engine, Aditya Datar

All Theses

Stochastic end-gas autoignition in SI engines, commonly called ‘knock’, limits attainable engine efficiencies. Multiple pathways to extend SI engine operation into knock-limited regions have been studied, including direct water injection (DWI). This study employs single-cylinder engine experiments and modeling to investigate the knock resistance offered by compression stroke water injections, which have shown to thermally stratify the cylinder in HCCI. In SI, thermally stratifying injections are expected to forcibly widen the cylinder temperature distribution by preferentially cooling the cylinder periphery. The end-gas is in the cylinder periphery; therefore, a cooler end-gas would result in longer ignition delays, thus providing knock …

Tradespace Exploration For Multiple Collaborative Vehicles, Mrunal Deshmukh

All Theses

Modern military operations demand systems that adapt to uncertain, rapidly changing missions across diverse terrains. Traditional single-platform vehicle design is insufficient for such complexity. This research introduces a hierarchical tradespace exploration framework for designing and evaluating families of heterogeneous ground vehicles under a System-of-Systems (SoS) architecture. The framework treats vehicle design as a co-optimization problem, where a “parent” vehicle (e.g., a Squad Multipurpose Equipment Transport) coordinates specialized “child” vehicles for reconnaissance, amphibious tasks, terrain traversal, and stealth missions. Unlike conventional approaches that optimize vehicles individually, this study emphasizes collaborative performance, resource sharing, and adaptability at the family level. Central to …

Comparison Of The Recent Icrp Occupational Intakes Of Rradionuclides Series To Annual Limits On Intake (Ali) In The United States For Select Radionuclides, Aidan B. Barker

All Theses

Dose coefficients (DCs) and secondary limit values (such as the annual limit on intake [ALI] and derived air concentration [DAC]) are useful and convenient quantities in radiation protection (RP) for estimation of radiological dose and the practical application of dose limits. DCs link radioactivity intake to dose while secondary limit values express a dose limit in terms of the type and extent of exposure. The International Commission on Radiological Protection (ICRP), an international organization which provides guidance and recommendations for RP, calculates, tabulates, and updates DCs following new findings and updated knowledge relevant to dose determination (e.g. improved human biokinetics, …

Enhancing Facial Expressiveness For Games Through Procedural Animation, Abhijit Varanasi

All Theses

Facial animation is one of the most important parts of bringing characters to life in video games and virtual experiences. This thesis explores a new approach to creating more expressive facial animations using procedural techniques and blended facial performance for more flexibility. The project uses FACS (Facial Action Coding System), which breaks down facial expressions into small, measurable muscle movements. By building a facial rig based on these muscle units, the character’s face can be animated in a way that reflects real human emotion. The animation in this work is not just pre-recorded, though it can respond in real-time to …

Plant Community Responses To Wildfire, Timber Thinning, And Bison Reintroduction On The Northern Great Plains, Ethan H. Van-Derpoel

The Northern Great Plains (NGP) is one of the largest intact grasslands remaining in the world. These two studies examine a few of the ecological concerns on the NGP today. First, the woody encroachment of conifers into grasslands and the effects of wildfires. Second, the effects of bison (Bison bison) reintroduction on plant communities. In Chapter 1, this study aims to examine the effects of wildfire and mechanical timber thinning, using a two-by-two factorial design, on plant community responses and forage quality in the Bull Mountains area of central Montana, USA. We found that our treatments had varying …

Unloved Ecologies, Ellen Griffin

All Theses

Unloved Ecologies is an exhibition of ceramic sculptures that stage encounters between human and nonhuman bodies. Through it, I investigate the intersections of queer identity and ecology to reevaluate what society often deems “unlovable.” By working with the language of Queer Ecology, I explore the tensions between protection and vulnerability, as well as between cultivated order and wild resistance. Ceramic sculpture is my mode for examining moments of transformation, repair, and growth, and natural processes function as metaphors for the ways external pressures shape individuals. My overall goal is to explore the ecological processes of change and examine how our …

Investigating Workplace Management Conditions Influence On Interpreter Motivation And Interpretive Program Performance, Jessica M. Henry

All Theses

Organizations, including non-profit and government agencies such as the National Park Service and nature centers, that provide informal education (also known as interpretation) seek ways to achieve their mission and enhance their organizational performance (Anderson et al., 2022; Weiler & Ham, 2010). For informal education organizations that provide interpretation to visitors, one measure of organizational performance is the achievement of an organization’s desired visitor outcomes. Theory suggests that positive organizational performance is associated with positive workplace management conditions and high employee motivation. Thus, this study explored the relationships between interpreters’ perceptions of workplace management conditions, motivation, and performance on interpretive …

Evaluating High School Students’ Perceptions About The Construction Industry: Views To Consider And Improve The Inclination Towards A Career In Construction, Radhika Soni

All Theses

The construction industry continues to face a critical workforce shortage, intensified by declining interest among high school students who often hold narrow or negative views of construction careers. This study examines students’ perceptions of the construction industry, the experiences that shape those perceptions, and the factors influencing their likelihood of pursuing construction-related careers. A mixed-methods design was used, consisting of a survey distributed to students in Grades 9–12 across the upstate region of South Carolina. Quantitative analyses included descriptive statistics, Kruskal–Wallis tests, Mann–Whitney U tests, and Spearman correlations, while qualitative responses were examined through thematic analysis.

Findings show that most …

Dynamic Topology Optimization And Experimental Validation Of Reinforcement For Pcb Robotics, Ryan G. Semler

All Theses

Ongoing research between Clemson University and the NASA Jet Propulsion Laboratory (JPL) has been conducted to characterize and assess rigid-flex printed circuit board (PCB) robotics subjected to dynamic loads. A lightweight, PCB lunar rover, PUFFER (Pop-Up Flat Folding Explorer Robot), was designed by NASA JPL for Mars missions, but its deployment for lunar missions has been investigated as well. Its current architecture, however, is insufficient for navigating and surviving the lunar environment, and reinforcement has been recommended as a solution to protect larger panels.

This research work presents a dynamic topology optimization process for PCB panel reinforcement. A thorough literature …

Harnessing Irrationality, Jennifer E. Smith

All Theses

My thesis work considers the presence of objectifying gazes in representations of women in Western visual media and pop culture. I reference film, television, short form content shared on social media, and pornography to identify and repurpose tools of objectification in my large scale drawings and animated GIFs. I compare the objectifying tropes present in contemporary entertainment media and pop culture to those present in the Western art historical tradition of the reclining female nude, mythology and folklore, and pornography. Using these comparisons, I discuss objectification in terms of passive and active, consumption and appetite, and idealization and devaluation. I …

Optimal Control Of Human Exercise Using An Individualized Physiological Three-Tank Model And Dynamic Programming, Asal Lotfi

All Theses

This thesis develops a physiologically inspired three-tank model of human bioenergetics to describe and optimize fatigue and recovery during exercise. The aerobic, phosphagen, and glycogen systems are modeled as coupled reservoirs whose states constrain instantaneous power output. Building on this representation, dynamic programming is used to compute pacing strategies that respect physiological limits while maximizing task-specific goals such as peak power or total work over a fixed duration, enabling individualized, goal-driven exercise prescriptions. The three-tank dynamics are formulated in continuous time and then discretized under a zero-order-hold assumption for simulation and optimal control. Model parameters are linked to standard field …

Dwelling / Knowing / Loving: Imaging The Immanent Present, Joel Pasquarelli

All Theses

This thesis serves as an attempt to articulate, understand, and testify to my experiences within the immanent present. Defined as moments where the world impresses itself upon my awareness with such a force that it eclipses all else, the experience of immanence is necessarily undeniable and ephemeral. These moments are accompanied by a combined sense of exultation in the world’s existence and poignant longing for something beyond. I feel as though I am embedded within something great and meaningful, as the material world acts upon me, yet I remain ever unsatiated by this experience as the world inevitably returns once …

Understanding Policy Transfer Under Decomposition And Coordination: Sequential Reinforcement Learning With Relaxation-Based Feasibility Control, Aannand Lal

All Theses

This thesis investigates how decomposition and coordination (D&C) choices influence exploration, learning, and transfer in reinforcement learning (RL) based design frameworks. A unified methodology is developed to evaluate generality under decomposition and to demonstrate sequential coordination on a representative physical task. The generality study holds the underlying physics constant while varying problem presentation - specifically scalarization weights, objective orientations, and feasibility handling. A train-evaluate matrix is constructed in which each trained policy is assessed across all alternative decompositions. Set-based diagnostics quantify generality through exact-match identity, Jaccard similarity of distinct feasible states, total feasible coverage, and Pareto-front quality. Results show that …

Soundscapes Of Alaska's Arctic Coastal Plain: Implications For Wildlife, Maxwell Plichta

Biological Sciences

Passive acoustic monitoring is an effective tool for collecting baseline acoustic data in remote locations and for advancing our understanding of soundscapes, the sound that emanates from a landscape. Terrestrial Arctic soundscapes remain understudied. The Arctic Coastal Plain (ACP) of northern Alaska is an ecologically, culturally, and economically significant region, containing a mix of land-uses and management practices. This study leverages a spatially large (~8,000 km2), multi-year dataset of acoustic recordings and paired images collected across the ACP to investigate how natural and anthropogenic factors influence the soundscape (Chapter 2), and how acoustic metrics influence the behavior of caribou (Rangifer …
