The Effects Of Overwash On Barrier Island Evolution And Building A Barrier Island Measure Of Resistance, Beth Thomas
The Effects Of Overwash On Barrier Island Evolution And Building A Barrier Island Measure Of Resistance, Beth Thomas
Theses and Dissertations
Barrier islands are critical for coastal communities, as they serve as a natural buffer against storm surge, waves, and the effects of rising sea levels, protecting life and property. These islands continuously evolve due to both normal and severe environmental conditions; global warming makes it increasingly difficult to predict the evolution of these islands due to increases in storm frequency and intensity. We present a cellular model of barrier island evolution consisting of biotic and abiotic processes including the effects of vegetation, wind, ocean currents, and gravity. The model is used to predict the future evolution of barrier islands off …
Machine Learning-Based Spatio-Temporal Modeling Of Climate Dynamics And Desertification In The Sahara–Sahel Region, Stephen M. Tivenan
Machine Learning-Based Spatio-Temporal Modeling Of Climate Dynamics And Desertification In The Sahara–Sahel Region, Stephen M. Tivenan
Theses and Dissertations
Arid climate classifications are threshold-dependent and easily interpretable mappings that are widely used in ecological, agricultural, and climate-related studies. These classifications inform scientific understanding, support policy and land management decisions, and provide an intuitive summary of environmental conditions. Despite their usefulness, traditional arid climate classifications often fail to quantify uncertainty, incorporate spatial context, or account for complex relationships among relevant environmental variables. Existing approaches to uncertainty assessment have largely relied on comparing classifications across multiple datasets or alternative formulas, but these methods generally overlook important spatial dependence and latent structure in the data.
This dissertation develops three machine learning-based statistical …
In-Between Echoes, Jiayi Liang
In-Between Echoes, Jiayi Liang
Theses and Dissertations
In this dissertation, I explore memory, diaspora, labor, and intergenerational trauma through constructed photography and experimental film. Informed by Homi K. Bhabha’s concept of the Third Space, I examine how identity is shaped through displacement, cultural negotiation, and inherited memory. Drawing from my relationship with my grandmother and my experience as a Chinese woman living in diaspora, I consider labor as both survival and care, tracing how domestic gestures and emotional structures continue across generations. Through collage, reconstruction, and animation, I rework fragments of family archives, colonial landscape imagery, and personal photographs to address grief, racialized perception, belonging, and the …

Exploring The Lived Experiences Of Families Of Students With Significant Disabilities In Accessing Community Transition Supports In Rural Settings, Michael David Green Jr.
Exploring The Lived Experiences Of Families Of Students With Significant Disabilities In Accessing Community Transition Supports In Rural Settings, Michael David Green Jr.
UNF Graduate Theses and Dissertations
The transition process beyond high school can be daunting for students with disabilities and their families. Families often encounter difficulties accessing community-based supports after students leave the K–12 education system despite federal legislative mandates under the Individuals with Disabilities Education Act (IDEA) and the Workforce Innovation and Opportunity Act (WIOA). Rural contexts further complicate the experience for families accessing adult services after high school. The current hermeneutic phenomenological study explored how families of students with significant disabilities experienced accessing community transition supports after leaving high school in rural contexts. Through the lens of van Manen’s hermeneutic phenomenology, the study explored …

Dissertations, Master's Theses and Master's Reports
The transportation sector currently accounts for nearly 30% of global energy consumption, necessitating urgent advancements in vehicle efficiency to meet Net Zero targets. Leveraging connectivity and automation, this dissertation proposes and validates methodologies to reduce the energy consumption of light-duty vehicles at both fleet and individual levels.
First, a validation framework is developed to bridge the “simulation-to-real world” gap in Cooperative Automated Vehicle (CAV) research. Moving beyond virtual simulations, the study establishes a methodology for physically validating centralized control architectures via a custom Cellular V2X network. By synchronizing vehicle-powertrain models with physical test vehicles, the framework successfully orchestrates complex arterial …
Evaluating Willow Establishment With Biochar For Remediation Of Mine Waste Soils: Amendment Ph Determines Plant Biomass And Metal Mobility, Madeline R. Webb
Evaluating Willow Establishment With Biochar For Remediation Of Mine Waste Soils: Amendment Ph Determines Plant Biomass And Metal Mobility, Madeline R. Webb
Dissertations, Master's Theses and Master's Reports
Heavy metal contaminated mine tailings (“stamp sands”) from historic copper mining inhibit plant establishment and contribute to ongoing metal contamination. Biochar amendments may enhance plant growth and reduce metal mobility in highly permeable mine waste soils, but the efficacies of different application methods or biochar sources and composition are uncertain. We evaluated different biochar sources (neutral or alkaline pH) and application methods (either mixed or layered) for planted willow growth, moisture retention, and metal mobility. A 10-week growth chamber experiment assessed plant performance, heavy metal content and heavy metal mobility in soil leachates and plant tissues. Biochar pH was the …
Origin Of The World-Class Eagle, Eagle East, And Tamarack Ni-Cu-Pge Deposits And Comparative Analysis With Other Midcontinent Rift- And Siberian Trap-Related Intrusions, Robert M. Nowak
Dissertations, Master's Theses and Master's Reports
The 1.1 Ga Mesoproterozoic Midcontinent rift hosts the Eagle, Eagle East, and Tamarack Ni-Cu-PGE deposits and Embayment Prospect. These deposits are hosted by ultramafic igneous rocks and have some of the highest Ni-Cu grades on Earth. We use new bulk-rock data and published datasets (bulk-rock, mineral chemistry, and isotopic analyses) to examine major, minor, and trace element trends of both Midcontinent rift-related alkaline and tholeiitic intrusions. In addition, we compare the geochemical data to local kimberlite-hosted lower-crustal xenoliths and local igneous (Archean) and sedimentary (Paleoproterozoic) country rocks. We found the peridotite magma compositions dominantly consist of primitive mantle compositions with …

Drawing on a qualitative analysis of existing literature, the study explores how AI is increasingly integrated into political campaigns, election administration, and voter engagement. Key benefits include enhanced data analysis, personalized political messaging, and improved efficiency in campaign operations. AI also supports real-time fact-checking and more accurate vote tabulation, which can strengthen transparency and trust in electoral processes. However, the thesis emphasizes that these advantages are accompanied by significant challenges. AI technologies enable the rapid creation and dissemination …
Hybrid Patchtst And Physics-Based Framework For Predicting Lithium-Ion Battery State Of Health, Pavan Ravuri
Hybrid Patchtst And Physics-Based Framework For Predicting Lithium-Ion Battery State Of Health, Pavan Ravuri
Honors Undergraduate Theses
Accurately forecasting the state of health of lithium-ion batteries is critical for improving performance, reliability and lifetime in energy storage applications. Battery capacity degrades into a nonlinear pattern over cycling due to electrochemical processes where neither purely data driven nor physics-based models can capture alone. This study looks at a hybrid framework combining that PatchTST patch-based transformer architecture with physics-based features derived from the solid electrolyte interphase and pseudo two-dimensional models. Physics inspired proxy features were computed from cycling data and concatenated with electrochemical measurements as added input channels before patch segmentation. There are five model configurations that were evaluated …
The Role Of Resistance Training In Managing Menopause-Related Changes, Alyson K. Strauss
The Role Of Resistance Training In Managing Menopause-Related Changes, Alyson K. Strauss
Honors Undergraduate Theses
Resistance training serves as a critical non-pharmacological strategy for mitigating the physiological and psychological declines associated with the menopausal transition. This natural biological phase, marked by declining estrogen levels, typically leads to accelerated bone mineral density loss, sarcopenia, metabolic regulation disturbance, and heightened mood disturbances. To evaluate the efficacy of targeted exercise interventions, a systematic review was conducted following PRISMA guidelines. From an initial pool of 60 relevant articles, 13 studies met the specific inclusion criteria, focusing on structured resistance training protocols for perimenopausal, menopausal, and postmenopausal cohorts.
The synthesis of these studies indicates that resistance training is a highly …
Lie-Galois Theory, Giovanni Reed
Lie-Galois Theory, Giovanni Reed
Honors Undergraduate Theses
Differential equations are a much-studied topic in the field of mathematics, as well as other sciences, such as engineering, economics, and biology. While much is known concerning these, there is still a large gap in our knowledge about such equations. It is important therefore, both to mathematics and other sciences, that we gain a more complete knowledge of differential equations, in particular the nature of their solutions. In this research, we investigate the solution space of linear ordinary differential equations (ODEs) from the standpoint of differential algebra. Differential algebra allows an ODE to be treated similarly to a polynomial, allowing …
Dominating Hadwiger's Conjecture For 2k2-Free Graphs, Thomas Tibbetts
Dominating Hadwiger's Conjecture For 2k2-Free Graphs, Thomas Tibbetts
Honors Undergraduate Theses
A dominating Kt minor in a graph �� is a sequence (��1,…,��t) of pairwise disjoint non-empty connected subgraphs of ��, such that for 1≤��< ��≤��, every vertex in ��j has a neighbor in ��i. Replacing “every vertex in ��j” by “some vertex in ��j” retrieves the standard definition of a ��t minor. The strengthened notion was introduced by Illingworth and Wood in 2024, who asked whether every graph with chromatic number �� contains a dominating ��t minor. This is a substantial strengthening of the celebrated Hadwiger’s Conjecture, which asserts that every …

Sequential extraction using ultra – pure water followed by organic solvents, hexane, dichloromethane (DCM), and ethyl acetate (EA), was evaluated across water – based, silicone – based, oil – based, and hygiene product matrices. Analysis was performed using Direct Analysis in Real Time – High Resolution Mass Spectrometry (DART – HRMS), and extraction efficiency was assessed through spectral correlation with neat reference samples. Results demonstrated that solvent performance was highly dependent …
The Self And The Afterlife, Elizabeth Schmidt
The Self And The Afterlife, Elizabeth Schmidt
Honors Undergraduate Theses
My thesis explores aspects of the self in the context of a classical theistic Heaven: a perfect place with perfect persons. The relevant philosophical literature raises issues on free will, personal identity, and the desirability of Heaven. Will there be free will in Heaven? If yes, inhabitants of Heaven can introduce evil to it. This conflicts with theists' assumption that Heaven is perfect. If there is no free will in Heaven, then God could have created a world in which there is good without evil by omitting free will. In this case, God allows unnecessary suffering on Earth, which nullifies …
Assessing Physiological Arousal During A Standard Versus Inverted Vigilance Task Using Heart Rate Variability, Taha Riaz
Honors Undergraduate Theses
Background: Vigilance tasks require sustained attention over long periods of time while monitoring for rare critical signals. Inverted or reverse vigilance/sustained attention response tasks (SART) may impose greater response-control demands. Although prior studies have compared these tasks behaviorally, there are fewer investigations examining whether they differ in physiological arousal as indexed by heart rate variability (HRV).
Method: Undergraduate students from UCF completed a variation of either the X-CPT (standard vigilance task) or the CPT-3 (inverted/SART) task. Electrocardiogram data was recorded continuously. Data from 40 participants were analyzed. HRV was indexed using frequency domain analysis using the low-frequency to high-frequency ratio …
Immigration Securitization And Educational Access: The Impact Of U.S. Immigration Policy On International Students, Cossir Carter
Immigration Securitization And Educational Access: The Impact Of U.S. Immigration Policy On International Students, Cossir Carter
Honors Undergraduate Theses
This study examines the securitization of international students within the broader transformation of United States immigration policy from the post-9/11 era to the present administration. Following the September 11 attacks, immigration governance was increasingly reorganized under a national security framework, significantly altering the regulatory environment surrounding student visas. Subsequent policy shifts have intensified monitoring mechanisms and administrative controls that directly shape international students’ access to education and mobility. Given the sensitivity of immigration-related participation in the current political climate, this research employs qualitative policy analysis rather than direct student surveys. Under the Trump administration, this securitization intensified through stricter visa …
From Lap To Map: How Musical Scale, Place, And Play Drive The Interconnected Mario Kart World, Cameron Cummins
From Lap To Map: How Musical Scale, Place, And Play Drive The Interconnected Mario Kart World, Cameron Cummins
Honors Undergraduate Theses
With their deserts, castles, and ghost houses, the environments of Super Mario games are colorful, whimsical, and charming, but why are they so compelling, and what happens when our analysis of these environments extends beyond individual levels to expansive game worlds? Drawing on Cresswell’s theory of place (2014) and recent work on musical place-building in Mario Kart 8 (Heazlewood-Dale, 2024), I propose a spectrum between localized and globalized scale in games. As game environments become increasingly globalized, the music may be similarly altered to account for this shift in scale. Consequently, players may then encounter a broader, less musically congruent …
Vibration-Based Control Of Nonlinear Dynamic Systems, Ossyris N. Bury
Vibration-Based Control Of Nonlinear Dynamic Systems, Ossyris N. Bury
Honors Undergraduate Theses
This thesis investigates vibration-based stability as a mechanism for achieving self-stabilizing nonlinear dynamic motion in engineered systems. Inspired by biological hovering flight, in which periodic wing motion can passively enhance stability, the study explores how controlled oscillations can be used to stabilize otherwise unstable mechanical configurations. The research centers on a simplified dynamic model based on the Kapitza pendulum, an inverted pendulum with a vertically oscillating base, which serves as a foundation for understanding vibration-induced stabilization. Analytical modeling using Lagrangian mechanics is employed to derive the governing equations of motion and identify the excitation conditions required for stable inverted behavior. …
Ai-Thropology: A Study Of Artificial Intelligence Use In Anthropology, Carly R. Junod
Ai-Thropology: A Study Of Artificial Intelligence Use In Anthropology, Carly R. Junod
Honors Undergraduate Theses
This study examines how undergraduate anthropology students utilize Artificial Intelligence tools in their coursework and the impact on perceptions of learning. As the use of AI becomes more commonplace, I investigated whether it has been integrated into the praxis of undergraduate anthropology students. Using a Likert-scale survey distributed to 26 anthropology students across multiple subfields, I investigated AI usage patterns, perceptions of academic integrity, and correlations with demographic factors. The results reveal that anthropology students exhibit conservative AI usage patterns, with the majority rarely using AI for core academic tasks such as drafting papers. ChatGPT and Grammarly emerged as the …

Evaluation Of The Long-Term Sealability Performance Of Aramid Fiber Nitrile-Based Gaskets, Salome Ramirez
Honors Undergraduate Theses
The reliability of sealed, oil-filled containers is critical for maintaining the operation of high-voltage energy systems, in which the sensitive electronics need to be isolated from the cyclic conditions associated with outdoor environments. New materials bring the possibility of extending service lifetimes and maintenance intervals. Aramid fiber nitrile-based gaskets are an attractive alternative to conventional gasket choices due to their long-term stability in various environments and compatibility with porcelain, metals, and plastics. For newly designed porcelain-to-metal fittings, understanding the behavior of the candidate gasket material under realistic loading conditions is essential to ensure long-term seal integrity and equipment safety. Traditional …
Being-Online: Towards A Phenomenological Account Of Virtual Place And Narrative Selfhood, Ben Runey
Being-Online: Towards A Phenomenological Account Of Virtual Place And Narrative Selfhood, Ben Runey
Honors Undergraduate Theses
The intent of this thesis is to explore and explicate a phenomenology of virtual place by investigating how environments motivated by computers and smart devices appear within lived experience as well as how these virtual places found and mediate interpretative narratives of self-identity. Many individuals today spend vast portions of their waking hours concerned with or engaged within virtual domains. While contemporary scientific research aims to uncover the effects of this on human psychology, physiology, and social structures, phenomenology must be utilized to reveal the existential, lived dimensions of virtual places. This investigation will be founded upon, but not limited …
Investigation Of The Impact Of The Shape Of The Wings On Formula E Racing Car Performance: Enhancements For Optimal Aerodynamics, Ednie Marthe Adlaikah Jozil
Investigation Of The Impact Of The Shape Of The Wings On Formula E Racing Car Performance: Enhancements For Optimal Aerodynamics, Ednie Marthe Adlaikah Jozil
Honors Undergraduate Theses
The aerodynamic performance of a Formula E chassis significantly dictates its overall race efficiency, directly impacting crucial parameters such as battery range and thermal management. This thesis investigates the external aerodynamics of the baseline Gen 2 Formula E car and evaluates the performance gains of two novel aerodynamic packages: a "Fully Modified" configuration and a "Flat Rear Wing" design. Computational Fluid Dynamics (CFD) simulations were conducted to analyze drag coefficients (Cd), downforce generation, and vehicle wake structures at race-relevant free-stream velocities (e.g., 37 m/s and 89 m/s). To ensure numerical robustness, the computational setup was validated using a smooth sphere …
To Print A Remake: An Analysis Of Hollywood Remakes And Their Cultural Value, Connor F. Seaton
To Print A Remake: An Analysis Of Hollywood Remakes And Their Cultural Value, Connor F. Seaton
Honors Undergraduate Theses
In recent years, audiences and movie critics have expressed concern that Hollywood’s growing reliance on remakes, sequels, franchises, and similar adaptations has led to a broader worry that originality is fading from modern cinema and that the industry is instead focused on using adaptations to maximize profits. Although adaptation is often seen as a commercially driven framework for reproducing existing intellectual property in a new media format, this thesis argues that it should be recognized as an autonomous cultural category with its own artistic, historical, and social significance and merit. By analyzing adaptation scholarship and reviewing its complex historical development, …
Evaluating The Comparison Of Different Body Locations For Data Collection Using Galvanic Skin Response Of Forensic Chemistry Students When In Lecture And Laboratory Environments, Elisa Guerrero
Honors Undergraduate Theses
Anxiety is the response that humans can have when exposed to a stimulus. It can be caused by a multitude of factors, such as psychological, biological, or physiological stimuli. Anxiety can be presented as a state or as a trait in a person. Trait anxiety is typically seen as a more stable personality trait, whereas state anxiety is a more intense temporary emotional state. In our study, anxiety was regarded as a more state-like characteristic. A galvanic skin response (GSR) Shimmer3+ device can measure skin electro-conductance changes following stimulation. In a situation where a participant is experiencing anxiety, levels of …
High-Resolution Mapping Of Soil Moisture Variation Using Uas Thermal And Multispectral Imagery, Jackline Amma Timah
High-Resolution Mapping Of Soil Moisture Variation Using Uas Thermal And Multispectral Imagery, Jackline Amma Timah
Theses and Dissertations
In agricultural landscapes, soil moisture regulates hydrologic partitioning, nutrient transport and water quality, land-atmosphere energy exchange that shapes local climate, and ecosystem resilience. However, traditional monitoring approaches, such as in-situ sensors and satellite imagery, often lack the spatial resolution required to capture fine-scale soil moisture variability. This study evaluated whether unmanned aerial system (UAS)-derived thermal, multispectral, and terrain variables can capture fine-scale spatial variability in volumetric water content (VWC) within an SRB in central Illinois.
High-resolution imagery was collected and paired with 50 field-measured VWC observations. Land surface temperature (LST), vegetation indices (NDVI and NDRE), spectral bands, and slope were …
Characterizing A Low-Gradient Stream In Central Illinois As Gaining Or Losing And Observing Seasonal Changes In This Behavior, Eric Timothy Brunner
Characterizing A Low-Gradient Stream In Central Illinois As Gaining Or Losing And Observing Seasonal Changes In This Behavior, Eric Timothy Brunner
Theses and Dissertations
While the seasonal behaviors of low-gradient streams have been studied, the behavior of surface water and groundwater interactions within low-gradient streams in glaciated terrain is not fully understood. A third order, low-gradient glacial stream with a saturated riparian buffer in central Illinois was studied to determine the direction of flow between the surface water and groundwater. The goals of this study were to determine 1) whether the stream was gaining or losing water, and 2) whether the gaining or losing nature of the stream-aquifer system changes seasonally. At both an upgradient and downgradient location, two wells were installed: one in …
An Application Of Molecular Dynamics To Hed Plasma Physics: Point And Group Defect Diffusion In Coulomb Crystals, Levi Webb
Theses and Dissertations
Molecular dynamics (MD) simulations are used to explore the microscopic behaviors of complex systems that cannot be easily studied experimentally. In particular, the microphysics of high energy density (HED) astrophysical plasma environments remain inaccessible by modern experiment---even in laser facilities, these plasmas exist only on short timescales that do not lend easily to investigation. The diffusion of point and group defects through crystallized plasmas in the cores of white dwarfs and neutron star crusts, called Coulomb crystals, has potentially macroscopic implications for the evolution of these bodies. Thus, I employ the widely-used MD code LAMMPS to simulate small Coulomb crystal …
Type Ii Diabetes Treatment Comparison Via Compartment Modeling, Abigail M. Collins
Type Ii Diabetes Treatment Comparison Via Compartment Modeling, Abigail M. Collins
Theses and Dissertations
Type II diabetes mellitus affects one in ten adults worldwide, yet the effects of treatment type and adherence level on developing complications and quality of life have not been well characterized at the population level, and mathematical modeling offers a structured way to examine these dynamics. This thesis adapts the Boutayeb et al. (2004) model to incorporate dynamic treatment types and levels of adherence, producing nine scenarios in which complication development rate and complication recovery rate differed, to compare peak complications and quality of life across treatment and adherence conditions. Using a system of ordinary differential equations and compartment modeling, …
