Timing And Synchronization: Software And Hardware Approaches For Precision Maximizing, Christina Alicia Alejandra Carreon Jimenez

Open Access Theses & Dissertations

This thesis explores the design of synchronization mechanisms that allow multiple FPGA boards to operate as if they were a single coherent timing domain. The solutions span three layers: a software PLL for E1 telecommunication links, a PCIe-based timestamp exchange protocol, and a hardware-level multi-FPGA mesh architecture. Across these layers, the work demonstrates that practical, low-cost synchronization can achieve sub-microsecond accuracy without the burden of specialized hardware such as GPSDOs or White Rabbit infrastructure. Experiments show stable alignment within the nanosecond-microsecond range, validating the feasibility of the proposed methods for SDR and telecom applications.

Supporting Neurodiversity-Affirming Practice For Young Adults: Resource Development For A Level I Occupational Therapy Fieldwork Clinic, Grace Campbell

Capstone Projects

Neurodiversity-affirming and strengths-based practices are a growing area of focus within occupational therapy, viewing neurological differences as natural variations of human diversity rather than deficits to be corrected. This Doctoral Capstone Experience (DCE) focused on applying these perspectives within the Work-to-Work Clinic, a Level I occupational therapy fieldwork clinic that serves young adults with neurodevelopmental conditions such as Autism, ADHD, and intellectual disability. Commonly-used assessments and treatment materials at the clinic were outdated, deficit-focused, and poorly suited to this population’s developmental stage, leaving many clients with unmet needs. Additionally, Level I fieldwork students are still developing clinical reasoning skills and …

Pictured And Framed: A Media Analysis Of Local News Coverage Of The Unhoused In Fayetteville, Sabine Skoch

School of Social Work Undergraduate Honors Theses

Amid a growing housing crisis in Fayetteville, local media serves as an influential force in shaping public understanding of homelessness. This study examines how homelessness is framed in local news coverage through a reflexive thematic analysis of ten randomly selected articles published between May 2022 and November 2025. Guided by media framing and attribution theory, this analysis explores how causes, consequences, and solutions to homelessness are constructed within a rapidly growing Southern city.

Three central themes emerged. First, local reporting centers empathy through lived experiences and community testimonies, emphasizing dignity, vulnerability, and structural precarity rather than individual failure. Second, coverage …

Climate Vulnerability In Context: Interpretations Of Risk And Reality In Maine And New Hampshire, Sophie Hope Goodwin

Master's Theses and Capstones

This study examines the relationship between place-based climate vulnerability and belief in anthropogenic climate change in Maine and New Hampshire. While exposure-based models suggest that direct experience with environmental hazards should increase climate belief, sociological research emphasizes the role of political ideology and social context in shaping attitudes. Using county-level measures from the U.S. Climate Vulnerability Index combined with individual survey data from the Pine Tree State Poll and Granite State Poll, this study evaluates whether multidimensional climate vulnerability is associated with belief that climate change is happening now and is primarily caused by human activities. Results from three-step logistic …

Developing A Questionnaire For The Interoceptive Awareness Of Stuttering, Leslie Williams

Graduate Theses and Dissertations

Stuttering is commonly measured through its overt characteristics (blocks, prolongations, and repetitions). This equates to stuttering “severity,” or the frequency of these behaviors. This method, however, does not reflect the lived experience of adults who stutter. This “measurement problem” has been the subject of numerous studies. In this graduate thesis, the measurement problem is addressed by using qualitative data previously gathered by Malcolm (2024) from adults who stutter about the internal experience of stuttering to create survey. Quotes from adults who stutter were gathered, categorized, edited for clarity, and formatted into a survey, The Multidimensional Interoceptive Awareness of Stuttering Scale …

Marvelous And Disturbing: Surreal Imagery, Elaboration And The Limits Of Persuasion In Women's Health Journalism, Shelby Elizabeth Gill

Graduate Theses and Dissertations

Since the 1930s, surrealism has lent its abstract hand to journalism, offering a visual language for topics that resist literal depiction. Given its historical and often fraught association with the female form, surrealist imagery has found a natural home in editorial coverage of women's health, most recently in reporting on endometriosis, a condition whose invisible, stigmatized and difficult-to-articulate experience makes conventional photojournalism an inadequate representational tool. The present study experimentally compared surreal imagery, realistic imagery and a text-only control condition to assess their effects on knowledge acquisition, comprehension, attitudinal responses, perceived risk and behavioral intentions related to endometriosis in a …

Mitigating Inertial Measurement Unit Drift In Quadcopter Trajectory Tracking Using Kalman Filter Sensor Fusion With Global Positioning Measurements, Juan Sandro Caballero Aguilar

Graduate Theses and Dissertations

Unmanned Aerial Vehicles (UAVs) like quadcopters are widely used in civilian and military applications such as farming, photography, search and rescue missions, and autonomous navigation and motion. The performance and stability of these systems depend on accurate state estimation, which provides real-time information about the vehicle’s position, velocity, and orientation. However, achieving reliable state estimation is challenging due to sensor noise, measurement uncertainty, and inaccurate modeling. Common navigation sensors such as the Global Positioning System (GPS) and Inertial Measurement Units (IMUs) exhibit complementary characteristics. GPS provides absolute position measurements but suffers from noise, multipath effects, and low update rates, while …

Asynchronous Polymorphic Logic Locking, Kelby Haulmark

Graduate Theses and Dissertations

This work presents Asynchronous Polymorphic Logic Locking (APLL), a logic locking methodology that integrates polymorphic logic within the Multi-Threshold NULL Convention Logic (MTNCL) paradigm. APLL achieves Boolean satisfiability-attack resilience through a fault-based logic stripping approach followed by logic restoration, while leveraging the analog, dual-functionality of polymorphic gates to impede reverse engineering and removal attacks. In contrast to comparable SAT-resistant logic locking techniques, APLL provides inherent resistance to reverse engineering, reducing the viability of a broad class of attacks that rely on access to the locked netlist. A complete automated design flow is developed, enabling the transformation of combinational circuits into …

Mind The Gap: Exploring Sociocultural And Educational Factors Contributing To The Gender-Based Achievement Gap In Early Elementary Ela, William Matthew Mcgee

Graduate Theses and Dissertations

This study examined the sociocultural and educational factors contributing to the gender-based achievement gap in early elementary English Language Arts (ELA). While research has examined the gender-based achievement gap related to female-identifying students in STEM disciplines, there is less emphasis on the underperformance of male-identifying students in ELA. Earlier research often emphasized biological explanations rather than the influence of environment and instructional practices. This study was guided by the Expectancy-Value Theory and Social Role Theory to better understand how home environments, gender norms, instructional practices, and student perception of literacy influence student engagement and performance in Kindergarten through third grade. …

Collective Dissipative Charging And Energy Extraction In Quantum Batteries, Sagar Pokhrel

Graduate Theses and Dissertations

In this dissertation, we investigate the charging and discharging dynamics of a quantum battery composed of a collectively driven ensemble of $N$ identical two level systems coupled to a structured electromagnetic environment. The system is described using collective angular momentum operators in the Dicke basis, which provides a compact and physically transparent framework for analyzing collective light-matter interactions. Rather than treating dissipation as an unwanted source of loss, we explicitly use it as a mechanism for energy storage and work extraction. Starting from a coherently driven ensemble coupled to common reservoirs, we derive a master equation in Lindblad form under …

Self-Directed Violence In Athletes, Adela Vavrinova

Graduate Theses and Dissertations

Self-directed violence (SDV) in athletes comprises a spectrum of behaviors, including non-suicidal self-injury (NSSI), suicidality, and self-harming behaviors that can be embed- ded within sport contexts. Competitive sport environments may intensify psychological vulnerability through factors such as performance demands, body-image pressures, injury and rehabilitation stress, and norms that discourage help-seeking. This thesis synthesizes existing literature on SDV among athletes with the aim of clarifying how SDV is concep- tualized and measured, summarizing what is known about prevalence patterns, functions, and contextual risk factors, and identifying prevention and intervention strategies relevant to athlete systems. The reviewed evidence suggests the SDV literature …

Applying Motivational Interviewing-Based Health Coaching Within An Existing Exercise Referral Program: A Cost, Implementation, And Effectiveness Analysis, Zachary Joseph Friedman

In-Vitro Testing Of Light Wavelength To Detect Clots In Neonatal Extracorporeal Membrane Oxygenation Circuitry, Amanda Holmes

Dissertations and Theses (Open Access)

Background: Neonates requiring extracorporeal membrane oxygenation (ECMO) are at high risk for thrombotic complications, which contribute substantially to morbidity and mortality. Current circuit surveillance methods rely on intermittent visual inspection and indirect laboratory markers, both of which often detect thrombosis only after clinically significant progression. Optical approaches offer a non-invasive alternative for earlier clot visualization, yet the influence of illumination wavelength on detection performance under realistic ECMO conditions remains incompletely characterized.

Methods: This study evaluated wavelength-dependent clot detection performance in a controlled in-vitro neonatal ECMO circuit model using a portable imaging prototype designed to emulate bedside workflow. Twelve independent ECMO …

Enhancing Walleye (Ogaa) Recruitment: Evaluating Assisted Reproduction As A Mitigation Strategy, Douglass Keiser

Biology Graduate Theses

Over the past several decades, cold- and cool-water fish populations across the Upper Midwest, including Minnesota and Wisconsin, have shown troubling signs of decline. Among the most affected is the walleye/Ogaa (Sander vitreus), a species deeply embedded in the ecological balance, cultural identity, and economic vitality of the region, and central to the lifeways, treaty-reserved rights, and resource stewardship of Tribal Nations, including Ojibwe communities across the Upper Midwest. Despite ongoing stocking efforts and harvest regulations, many lake systems have experienced persistent declines in natural recruitment, prompting resource agencies to investigate the underlying causes. One such system is …

Biodiversity Risk And Firm Valuation: Regional Heterogeneity And Value-Chain Exposure In Global Capital Markets, Madelein Wentzel

Doctoral Dissertations (DBA)

This study examines whether biodiversity-related risks are priced in global equity markets and whether that pricing varies across regions, using a cross-sectional sample of more than 10,000 globally listed firms with biodiversity and financial data drawn from the fourth quarter of 2025. Consistent with a regional heterogeneity hypothesis, the results show that biodiversity risk is significantly negatively associated with firm valuation in developed markets such as the United States and OECD countries, while the relationship is weaker, insignificant, or even positive in certain emerging regions including Latin America and the Middle East and Africa. The analysis further distinguishes between value-chain …

Evaluating Management Strategies And Technology To Improve Grazing Efficiency, Thomas E. Aquino

Department of Animal Science: Dissertations, Theses, and Student Research

Increasing land costs and labor constraints continue to challenge beef producers. More intensive practices can increase harvest efficiency; however, many producers are deterred from implementing them due to increased labor and management considerations. Virtual fencing (VF) may provide a reduced labor alternative to traditional fencing for managing intensive grazing. This dissertation evaluated management strategies and VF technology to improve grazing efficiency of stocker cattle systems. In Experiment 1, VF was used to effectively manage groups of steers grazing in adjacent paddocks separated by only virtual boundaries. There was no difference in VF containment (99%) when steers were grazing co-fenced, with …

From Reactive To Predictive: A Hybrid Trust-Mediated Adoption Framework For Data-Driven Maintenance In Distributed-Authority Aviation Environments, Dustin J. Foote

International Journal of Aviation, Aeronautics, and Aerospace

Modern aviation maintenance operates within increasingly data-intensive technological environments, yet the operational integration of predictive maintenance into routine decision-making remains inconsistent across sectors. Contemporary aircraft incorporate centralized maintenance computers and condition monitoring architectures capable of fault aggregation, exceedance capture, and trend-based data collection. Although prognostics and health management research continues to advance detection and prediction methods, implementation outcomes often depend on factors beyond analytical performance alone.

This paper examines predictive maintenance adoption in distributed-authority aviation environments and argues that constraints emerge less from sensing capability than from organizational structure, decision authority dispersion, and institutional trust dynamics. For purposes of analysis, …
