Building Eden Where We Can, Ireland Thomas

Graduate Studies Theses and Dissertations 2026

Building Eden Where We Can is a nonfiction memoir told in vignettes that come together to build a wider story. Through these vignettes, we are shown a narrator who is simultaneously surviving an abusive family, navigating a rare diagnosis, and coming to terms with their queerness. By braiding narratives and maintaining these various threads, this collection examines the intersections of sickness and religion, tradition and freedom, as well as fear and love. The lattermost dichotomy is represented in the narrator’s ultimate choice to leave behind a life of fear in the mother figure’s safe cage. In exchange, they receive a …

Thermomechanical Modeling Of Transpiration Surfaces For Hypersonic Propulsion, Spencer D. Smith

Graduate Studies Theses and Dissertations 2026

Hypersonic flight vehicles are a promising form of high speed passenger transport and efficient space access architectures. However, they are fundamentally a thermally limited technology. High heat fluxes exceeding 10 MW/m2 and gas temperatures between 3000-4000K can be found both within the engine, and on the outer surface. Current conventional engineering materials are non-viable at these conditions. In order to make these materials viable, active cooling strategies could be utilized. One particularly promising type is transpiration cooling, where a coolant is diffused through a porous surface. Although researched heavily in the 1960s, adoption is still minimal. Part of the reason …

Chirpi - Implementing And Analyzing The Chirp Communication Algorithm On Esp32 Hardware, Calvin Vanwormer

Graduate Studies Theses and Dissertations 2026

This work presents the implementation and experimental evaluation of the CHIRP communication algorithm on resource-constrained ESP32-S3 microcontrollers, bridging the gap between simulation-based validation and real-world deployment. CHIRP is a lightweight, fully decentralized peer-to-peer protocol designed for IoT networks with dynamic node membership, enabling runtime node join and leave operations without centralized coordination or global reconfiguration. The implementation comprises two main components: C-based node firmware running on FreeRTOS [1, 2], which implements the full CHIRP protocol including peer discovery, round-robin pairing, and firefly-inspired phase synchronization, and a Python-based experiment controller that orchestrates network experiments and collects per-node metrics without influencing protocol …

A Sensor Fusion And Optimization Framework For High-Resolution Power Outage Detection And Energy Asset Allocation, Elizabeth Trader

Graduate Studies Theses and Dissertations 2026

Existing power outage datasets lack the spatial and temporal resolution required for neighborhood- level risk assessment, and conventional energy system design optimizes for cost without accounting for community-level demand - resulting in inefficient and inequitable asset de- ployment. This dissertation presents IONCORTEX, a framework integrating three technical contributions: a heterogeneous sensor fusion pipeline combining social media signals with municipal infrastructure records for intersection-level outage detection at six-hour tempo- ral resolution, maintaining detection capability during telecommunications disruptions; a techno-economic analysis pipeline evaluating photovoltaic, battery storage, hydrogen, and diesel portfolios using NREL’s System Advisor Model with Monte Carlo uncertainty quan- tification; and …

Abig4l: A Semantic Reasoning Engine For Verilog Via Abstract Interpretation, Alicia Thoney

Graduate Studies Theses and Dissertations 2026

Modern Electronic Design Automation (EDA) flows treat structural and semantic reasoning as separate concerns. Synthesis structurally optimizes RTL, while dedicated verification teams validate functional behavior through testbenches and formal methods. This organizational divide means designers have no automatic, sound way to understand what their RTL does at the moment they are writing it. This thesis introduces AbIG4L (Abstract Interpretation of Generic 4-valued Logic), a static analysis framework that bridges this gap by delivering sound semantic reasoning automatically, directly within the hardware design loop.

The framework operates on a language-agnostic intermediate representation to compute sound over-approximations of hardware behavior across 0, …

Invisible Stress, Visible Patterns: How The Superwoman Schema Shapes Diet And Feeding Practices In Black Mothers And Their Youth During The Summer Versus School Months, Jillian Weathington

Graduate Studies Theses and Dissertations 2026

Background: Black mothers are frequently socialized into the Superwoman Schema (SWS), a coping pattern characterized by self-sacrifice and suppression of personal needs. Alongside significant caregiving demands, SWS may limit healthy eating opportunities, yet its relationship with diet quality (DQ) remains understudied. SWS may also intensify during unstructured summer periods. This study examined associations between SWS, perceived stress, and DQ among Black mothers and their youth during summer (T1) and school months (T2).

Methods: This observational within-subjects study included Black mothers (T1: n=51; T2: n=32; mean age 39.6±6.1) and their youth (mean age 10.6±0.3). Assessments occurred at two timepoints six weeks …

Dynamic Interactions Of The Compressible Reacting Flow With A Morphing Wall In A Supersonic Combustor, Mason R. Thornton

Graduate Studies Theses and Dissertations 2026

The influence of compressibility on supersonic reacting flows is explored by varying the area expansion ratio in a supersonic cavity combustor using a moving wall. In principle, this design allows on-the-fly adjustment of the combustor aft wall expansion ratio to accommodate variable inlet conditions and fueling rates. The variable back pressure broadens the operability envelope and ensures greater pressure rise recovery compared with a constant geometry combustor. The results demonstrate that modulating area expansion alters the combustor pressure distribution and can influence cavity flame dynamics. At sufficiently high equivalence ratios and compression levels, the back pressure induced by the moving …

Threads Of The Past: Exploration Of Banal Medievalisms In Russia's Invasion Of Ukraine, Evan Garrett Wallace

Graduate Studies Theses and Dissertations 2026

This dissertation examines how medieval historical narratives circulate within contemporary Western digital discourse surrounding Russia’s invasion of Ukraine. Russian political rhetoric has frequently invoked the medieval polity of Kyivan Rus’ to assert civilizational continuity between the medieval past and the modern Russian state. While these claims have been widely discussed in political and media contexts, less attention has been given to how such narratives appear within everyday online discourse. This study investigates how medieval references are mobilized, circulated, and interpreted within social media environments during the early conflict.

The research draws on a dataset of approximately 160,000 tweets collected from …

Sonic Costumes For Immersive Theme Park Storytelling: Developing Interactive Wearables To Enhance Performer, Audience, And Environment Interaction, Rachel Yee

Graduate Studies Theses and Dissertations 2026

Costumes enhance the themed experience through visual storytelling while also allowing performers to interact fluidly with a physical space. These garments are typically passive storytellers in theme parks, even if the performers interact directly with guests. Some garments coordinate with and react to elements of the themed environment, predominantly when worn by performers within live shows, parades, or streetmosphere settings. However, this interactivity is often available only at a distance from guests, causing a separation between audience and performer. For instance, lights on parade costumes, such as those throughout Disney’s Magic Kingdom Park, often synchronize only with parade floats and …

Infrared Systems And Their Application On Target Detection And Geolocation, Li Zhang

Graduate Studies Theses and Dissertations 2026

The infrared spectrum contains various sub-bands (from near infrared (NIR) to long-wave infrared (LWIR), which are specialized at different detection tasks. Objects that are well camouflaged to human vision can be highly noticeable in NIR imagery. For vision navigation, the varying illumination condition and the cluttered urban background poses challenges in the visible band but can easily be resolved by using a thermal imager operating in LWIR. Despite this potential, practical deployment remains limited by the lack of suitable platforms, task-specific datasets, and long-duration field validation. This dissertation addresses these gaps through the design and evaluation of two infrared sensing …

Ecological And Evolutionary Responses To Environmental Change In Two Large North American Mammals, George Zaragoza

Graduate Studies Theses and Dissertations 2026

Climate change and urbanization are resulting in rapid shifts in ecosystems. The effects of these changes are complex, and understanding how species respond is critical for predicting their impacts on genetic diversity and evolution, as well as changes in habitat suitability. Species can respond to these changes in two major ways: through behavioral or genetic adaptation, or by moving to more suitable habitat as conditions change. Adaptive genetic change, in particular, can support behavioral and physiological responses that enable species to persist in novel or changing environments, and understanding these changes can help predict how species will respond to anthropogenic …

Bowtie Antenna-Coupled Bi₂Te₃–Sb₂Te₃ Thermoelectric Detector For Millimeter-Wave Radiation, Rumana Zahir

Graduate Studies Theses and Dissertations 2026

We explore the development of antenna-coupled thermoelectric detectors for long-wavelength radiation using sputtered bismuth telluride (Bi₂Te₃) and antimony telluride (Sb₂Te₃) thin films. Detection in the infrared, millimeter-wave, and terahertz regimes is critical for sensing, imaging, and energy applications; however, many existing detectors rely on cryogenic operation, exhibit narrow spectral response, or require complex material systems. In this work, we investigate the feasibility of reliable, room-temperature long-wavelength detection using microfabricated thermoelectric thin films integrated with antenna structures. A systematic full-factorial experimental approach was employed to determine how sputtering parameters and post-deposition annealing influence …

Charge Transport Modeling Of Multifunctional Molecular Transistors, Romena Akter

Graduate Studies Theses and Dissertations 2026

Distinguishing between the current–voltage characteristic curves associated with different transport mechanisms in a molecular electronic device and an artifact arising from device-level disorder is a central challenge in the study of molecular electronics. Characterizing these mechanisms and connecting them qualitatively to molecular-level orbital alignment, electrode coupling, voltage division, energetic disorder, and reorganization energy requires not only experimental data but also a rigorous theoretical framework for extracting physically meaningful parameters from measured transfer characteristics. This dissertation addresses this challenge in Chapters 2, 3, and 4 by developing and applying four complementary transport models —Simmons tunneling, single-level Landauer, Marcus hopping, and McConnell …

From Motherhood To Sisterhood: Women Strike For Peace And The Transmission Of Feminist Consciousness, Olivia R. Aldrich

Graduate Studies Theses and Dissertations 2026

Women Strike for Peace (WSP) has traditionally been understood as a maternalist peace movement that emerged in response to atmospheric nuclear testing during the early Cold War era. This thesis argues that WSP’s history reveals a more nuanced relationship between motherhood, feminism, and political activism than existing scholarship has suggested. Rather than operating in distinct stages, maternalism and feminism operated simultaneously, working alongside one another throughout the organization’s history. Furthermore, this thesis builds upon Ednie Kaeh Garrison’s concept of feminist “radio waves,” arguing that WSP functioned as a transmitter of feminist consciousness, where ideas, organizational practices, and different political identities …

Effects Of Back-Pressure On Pseudo-Shock Systems, Emil C. Alunno

Graduate Studies Theses and Dissertations 2026

The isolator of a scramjet engine houses a pseudo-shock, a compressive flow structure that raises the static pressure and decelerates the incoming supersonic flow for efficient combustion while shielding the inlet from the elevated pressure downstream. Under sufficient back pressure the leading shock bifurcates and forms a shock train followed by a shockless mixing region, and the resulting system oscillates even under nominally steady conditions; this unsteadiness distorts the flow, can drive the pseudo-shock out of the isolator and unstart the inlet. This thesis experimentally examines how a pseudo-shock in a constant-area isolator at a measured entrance Mach number of …

Making Unsafe Sequences Unexecutable: Formal Protocol Enforcement For Cyber-Physical Systems, Arthur Amorim

Graduate Studies Theses and Dissertations 2026

Cyber-physical systems execute physical actions in response to software commands, making their communication protocols a primary attack surface. A stealthy attack is a sequence of individually valid messages that violates a required ordering, driving the system into an unsafe state without malware or protocol violation. Existing defenses examine messages or physical state in isolation, not protocol level sequences, and cannot prevent them. Preventing them requires enforcement that makes unsafe sequences unexecutable at the communication boundary.

Formal methods offer a principled path to enforcement, but no tool spans specification to safe deployed hardware. Model checking automates proofs but has no certified …

Developing A System Dynamics Framework For Sustained Digital Transformation, Quintal Battle

Graduate Studies Theses and Dissertations 2026

Despite significant organizational investments, more than 70% (Ellmer et al., 2025) of digital transformation initiatives fail. The existing literature evaluates transformation mechanisms as separate factors rather than as interacting, evolving feedback systems. This dissertation addresses this gap by developing and validating a system dynamics framework for sustained digital transformation. Guided by three research questions, the study examined the mechanisms that enable or constrain transformation, identified mechanisms distinctive to digital transformation contexts, and evaluated how existing change management frameworks guide transformation efforts. The study followed a six-phase methodology that combined a systematic literature review of peer-reviewed studies, empirical cases, causal loop …

Fgf19 As A Colorectal Cancer Serum Biomarker And Fgfr4 As A Mediator Of Anti-Her2 Resistance In Breast Cancer, Jordan Beardsley

Graduate Studies Theses and Dissertations 2026

The fibroblast growth factor 19 (FGF19)-fibroblast growth factor receptor 4 (FGFR4) signaling pathway regulates hepatic metabolism, bile acid (BA) synthesis, and hepatocyte proliferation. This signaling axis also is implicated in promoting tumor progression, therapeutic resistance, and metastasis in certain cancers.

In colorectal cancer (CRC) there is a critical need for non-invasive biomarkers for disease detection and monitoring. We identified FGF19 as a candidate CRC serum marker through meta-transcriptomics and found FGF19 to be expressed and secreted by CRC cell lines. Tumor-derived FGF19 was detectable in mouse serum at levels correlating with tumor volume in a subcutaneous xenograft model. RNA sequencing …

Sensory And Emotional Impacts On Modern Consumer Experiences, Winter E. Bland

Graduate Studies Theses and Dissertations 2026

This dissertation comprises two essays examining how environmental and psychological stimuli shape consumer experience, attitudes, and cognition. The first essay investigates the joint influence of scent temperature (warm versus cool) and scent arousal (stimulating versus relaxing) on experiential attitudes and cognitive performance in digitally mediated consumption environments. Across multiple lab experiments with biometric validation, findings reveal that these two scent dimensions interact to shape downstream outcomes. Warm, low-arousal scents (e.g., vanilla) enhance consumers' experiential evaluations of digital interactions but do not improve task performance, whereas cool, high-arousal scents (e.g., peppermint) boost cognitive efficiency and accuracy but do not elevate experiential …

An Examination Of The Impact Of School Context And Socioeconomic Status On Agency And Creative Productivity In Gifted High School Students, Elizabeth Bronson

Graduate Studies Theses and Dissertations 2026

This explanatory sequential mixed methods study investigated gifted high school students’ perception of the agency afforded them within school settings, and the relationship between these perceptions and their creative productivity. A sample of 140 students was drawn from a population of 966 identified gifted high school students. These students were contacted via their parents and asked to complete the Agentic Engagement Scale (AES) questionnaire which provided gifted high school students’ perceptions of the agency afforded at school. No significant differences in perceived agency were found across demographic variables, including socioeconomic status and school type. Of the respondents, 10 students were …

A Systematic Review And Characterization Of Privacy Noncompliance In Real-World Applications, Alexander E. Charkiewicz

Graduate Studies Theses and Dissertations 2026

Software applications increasingly rely on user data to provide their functionality, but improper handling of such data can lead to serious privacy noncompliance with applicable regulations and policies. A prominent example is the Facebook–Cambridge Analytica scandal, in which a third-party application collected the personal data of approximately 87 million Facebook users without users' consent. Despite growing attention to privacy compliance, two key challenges hinder the systematic understanding and analysis of privacy noncompliance. First, unlike security vulnerabilities, which have been systematically categorized through taxonomies such as the Common Weakness Enumeration (CWE), privacy noncompliance lacks a technical taxonomy describing how it manifests …

Vaccine Hesitancy In Arabic Discourse: A Multi-Method Social Media Study, Nada Dimashkieh Chehab

Graduate Studies Theses and Dissertations 2026

Vaccine hesitancy — the state of uncertainty about vaccination — poses global public health challenges, undermining efforts to prevent infectious diseases. It is also a contextual phenomenon, shaped by social and political forces. While survey-based research on vaccine hesitancy is abundant both globally and in the Arab world, humanities-oriented approaches using discourse analysis remain limited especially in Arabic on social media: some have tracked trends on Twitter, but virtually none have done so on Facebook. This dissertation addresses these gaps through a multimethod design combining Textual and Trend Analyses and Critical Discourse Study. It examines vaccine-related trends and discourses among …

An Exploration Of The Professionalization Of Graduate Students Using Rhetorical Theory, Jennifer M. Crowell

Graduate Studies Theses and Dissertations 2026

This qualitative study examines the professionalization of graduate students as a rhetorically mediated and relational process of identity development within an interdisciplinary doctoral program. While existing scholarship emphasizes institutional structures and formal mechanisms of professional preparation, less attention has been given to how graduate students experience professionalization at the individual level. This study addresses that gap by exploring how students interpret expectations, use rhetorical strategies, and construct professional identities across multiple disciplinary contexts.

Grounded in organizational rhetoric and community of practice theory, the study investigates how graduate students in the Texts & Technology Ph.D. Program at the University of Central …

An Empirical Comparison Of K-Nearest-Neighbors And Logistic Regression Classification Models, Jackson Cushing

Graduate Studies Theses and Dissertations 2026

This thesis presents an empirical comparison of two classification methods: Logistic Regression and K Nearest Neighbors (KNN). The primary objective of this research is to evaluate the strengths and limitations of each method when applied to real-world datasets. Several publicly available datasets on diabetes, breast cancer, heart attack risk, and cardiovascular disease, were analyzed. For each dataset, K Nearest Neighbors models were implemented in the same way logistic regression had already been applied. The results demonstrate that while logistic regression offers interpretable parameter estimates and performs well when the underlying predictor and outcome relationship is approximately linear, however KNN can …

Machine Learning Modeling Of In-Situ Effective Thermal Conductivities And Ablation Behaviors Of Ceramic Matrix Composites Under Hydrogen Combustion Environments For Gas Turbine Engines, Jayanta Bhusan Deb

Graduate Studies Theses and Dissertations 2026

Through the integration of experimental characterization, machine learning, deep learning, numerical modeling, and physics-informed artificial intelligence, this dissertation explores the thermal performance of polymer-derived ceramic matrix composites (CMCs) for hydrogen combustion environments. The polymer infiltration and pyrolysis (PIP) process was used to create Yttria-stabilized zirconia (YSZ)-fiber-reinforced ceramic matrix composites, which were then experimentally assessed under hydrogen torch and hydrogen combustion conditions typical of next-generation gas turbine and aerospace propulsion systems. Front- and back-surface temperature measurements were used to continually monitor thermal reactions, and post-test microstructural characterization and numerical simulations were carried out to evaluate material integrity and heat-transfer behavior. To …

Independent And Interacting Effects Of Co-Presence And Social Media 'Likes' On Online Disinhibition, Margaret M. Doheny

Graduate Studies Theses and Dissertations 2026

Social media platforms have fundamentally transformed interpersonal communication by creating environments in which behaviors are publicly reinforced through visible social feedback systems such as “likes.” Although prior research has linked online environments with increased disinhibition and negative behavior, existing literature has primarily focused on anonymity and invisibility as the primary mechanisms underlying these effects. However, the mechanistic role of physical and psychological co-presence in driving online disinhibition has received little empirical investigation. The central aim of the present study was to determine whether reduced social presence and the selective reinforcement of negative content contribute to online disinhibition and anticipatory reward-seeking …

Exploring The Experiences Of Late Age-On-Arrival Multilingual Learners In Postsecondary Education, Robyn D. Ecklund

Graduate Studies Theses and Dissertations 2026

Multilingual learners (MLs) are the fastest growing population in the United States public school system (Biondi et al., 2024; Kanno & Cromley, 2013; Perez & Morrison, 2016; Varghese & Fuentes, 2020). Within this population of students, there is a subset of students that arrive in the United States during secondary school. These “late age-on-arrival” students face significant linguistic, cultural and social challenges in their pursuit of postsecondary success after high school (Kanno, 2021; Kanno & Cromley, 2013; Perez & Morrison, 2016). This interpretative phenomenological analysis sought to answer the research question: what are the lived experiences of late age-on-arrival MLs …

Detecting Error In Ai-Generated Text: The Effects Of Authorship And Word Presentation Speed, Gabriela Flores Cruz

Graduate Studies Theses and Dissertations 2026

The increased us of artificial intelligent (AI) chatbots powered by Generative Pre-trained Transformers has raised concerns about users’ ability to detect errors of AI-generated text. This dissertation examined how readers identify inconsistencies in AI-generated expository passages using the inconsistency detection paradigm from comprehension monitoring research. Across two experiments, it investigated whether perceived authorship and word presentation speed influenced inconsistency detection. Experiment 1 used a 3 (author: human, AI, no author) × 2 (inconsistency type: internal, external) between-subjects design. Perceived authorship did not significantly affect hit rates, sensitivity, or response bias. Exploratory analyses indicated that reading comprehension and working memory predicted …

Lost Innocence, Found Martyrdom: Childhood War Exposure, Narratives, And Militancy In Hezbollah, Léa Faure

Graduate Studies Theses and Dissertations 2026

What explains participation in armed insurgent groups? Existing literature has examined psychological, individual, structural, and organizational dynamics of mobilization, but rarely looks at all three in tandem. This can be problematic, since these explanations cannot on their own explain variations in participation. Research on the effects of individual exposure to war-related violence also cannot explain why in conflict-ridden, organizationally dense environments, mobilization is still relatively rare despite widespread violent exposure. This study creates a unified theory of participation around the interaction between childhood exposure to war-related violence and relatable timely group narratives. Focusing on the case of Hezbollah in Lebanon, …

Gaining Voice, Creating Opportunity: An Exploration Of Non-Native English-Speaking Students’ Sources Of Self-Efficacy In U.S. College Public Speaking Classrooms, Desiree M M Flores-Molina

Graduate Studies Theses and Dissertations 2026

This qualitative dissertation explores the sources of public speaking self-efficacy among non-native English-speaking international students enrolled in U.S. college public speaking courses. The study applies Bandura's social cognitive theory to examine how students describe the experiences that shape their confidence and perceived ability to succeed, with attention to mastery experiences, vicarious experiences, verbal persuasion, and physiological and affective states. It also considers how classroom practices and instructor support contribute to or constrain students' confidence.

Data were collected through semi-structured student interviews, guided reflection artifacts connected to major speech assignments, and key-informant interviews with public speaking instructors. Thematic analysis was used …
