Improving Fairness On Semantic Segmentation Using Large Language Models, Samuel E. Burggraf

Electrical & Computer Engineering Projects for D. Eng. Degree

As machine learning systems are increasingly integrated into critical decision-making processes, ensuring fairness in their design and implementation has become a significant concern. While fairness research has primarily focused on specific protected attributes, less attention has been given to spatial fairness, which can affect individuals at specific locations. If fairness is not addressed, models may systematically underperform in certain regions or across populations which can lead to unequal access to accurate predictions and potentially biased decision-making. Fairness considerations should extend across all machine learning applications to align with the National Institute of Standards and Technology (NIST) guidelines of fair and …

From Invisible Injury To Measurable Impact: Exploring Associations Between Peripheral Biomarkers Of Neuroinflammation And Mental Health Outcomes After Mtbi, Lauren Leggett Smith

Psychology Theses & Dissertations

Mild traumatic brain injury (mTBI), often referred to as a “silent epidemic,” accounts for the majority of traumatic brain injuries worldwide and is increasingly linked to persistent psychiatric outcomes. Despite its prevalence, mTBI remains understudied due to diagnostic challenges, underreporting, and misperceptions of its clinical significance. The present study examined whether peripheral biomarkers of neuroinflammation and astroglial injury—tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and glial fibrillary acidic protein (GFAP)— mediate associations between mTBI history and psychiatric symptom severity, including depression, anxiety, and posttraumatic stress disorder (PTSD). Participants were 138 traumaexposed adults recruited from an urban university and surrounding community, with …

Temperature-Induced Uncertainty In Fixed-Context Retrieval-Augmented Generation, Steven Zeng, Murat Kuzlu

Cybersecurity Undergraduate Research Showcase

This study examines how decoding temperature affects output uncertainty in a fixed-context retrieval-augmented generation (RAG) system. We define uncertainty as the semantic dispersion among repeated answers under the same fixed retrieved context, with greater dispersion interpreted as higher uncertainty. To isolate this answer-generation variability from retrieval drift, each question was paired with a fixed retrieved context, and repeated generations differed only in temperature. The experiment used nine questions drawn from a machine-learning textbook corpus, with three questions each at easy, moderate, and hard difficulty. Each question was evaluated at five temperatures (0.0, 0.25, 0.5, 0.75, and 1.0) over 30 iterations, …

Phishing Restraint: University Simulated Phishing Campaigns, Alexander M. Abou Khir

Cybersecurity Undergraduate Research Showcase

Universities face heightened vulnerability to phishing attacks due to their open information-sharing culture and diverse user populations. This study examines how phishing exploits human factors within campus environments and evaluates three major training strategies: embedded phishing, microlearning, and role-based instruction to understand their individual and combined effectiveness. I explored studies that implement these strategies in pairs and use the strategies alone, identified trends in susceptibility reduction, behavioral reinforcement, and contextual relevance. I suggest that, while each method independently improves user awareness, multiple approaches offer stronger, more adaptable protection by addressing both psychological triggers and role-specific risks. The paper contributes a …

Hijacking The Prompt: A Survey Of Prompt Injection Attacks, Detection, And Defense In Large Language Models, Edward J. Griggs

Cybersecurity Undergraduate Research Showcase

Prompt injection attacks, ranked the number-one vulnerability in AI systems by OWASP's 2025 Top 10 for Large Language Model Applications, remain largely unsolved, and this survey examines why. As large language models (LLMs) are deployed across enterprise workflows, agentic systems, and consumer tools, their fundamental inability to distinguish trusted instructions from untrusted user data has created a persistent and expanding attack surface. This paper presents a structured taxonomy of prompt injection attack vectors, including direct injection, indirect injection, multimodal attacks, tool and agent exploitation, hybrid chained techniques, and autonomous propagating threats. These vectors are mapped across five impact categories (data …

Limitations Of Signature-Based Network Intrusion Detection Under Modern Traffic Conditions, Henry Guidry

Cybersecurity Undergraduate Research Showcase

Network Intrusion Detection Systems are tools used to monitor network traffic and alert to suspicious or harmful activity before it can cause harm. Signature-based versions of these systems are a foundation for intrusion detection, operating by finding common patterns and forming malicious signatures. However, three developments in modern network environments have greatly impacted the significance of Network Intrusion Detection Systems. These three developments are the near-complete adoption of end-to-end encryption, the use of sophisticated packet fragmentation techniques, and the processing demands of high-throughput networks. Encryption makes deep packet inspection practically infeasible by transforming inspectable payloads into ciphertext, forcing NIDS to …

Introduction to the Exhibit:

Today—exactly 250 years after the signing of the Declaration of Independence—many Americans trace the origins of the nation’s revolutionary sentiment to Boston, Massachusetts or Philadelphia, Pennsylvania. We remember the violence of March 1770, when red-coated British soldiers fired into a crowded Boston street, massacring innocent colonists and igniting outrage. We recall the patriotic defiance of the Sons of Liberty, who boarded three East India Company ships and dumped chests of imported British tea into the Boston Harbor in December 1773. We can still hear, too, the reverberations of the “shot heard ’round the world,” when British …

The Lived Experiences Of Master's Level Counselors In Professional Counseling Association Leadership, Catalina R. Kraft

Counseling & Human Services Theses & Dissertations

Leadership and advocacy are essential for all counselors (Lewis, 2022; McKibben, 2016; Paradise et al., 2010; Sweeney, 2022). However, within research and professional counseling associations, there appears to be a bias in which counselor educators are the expected, default leaders within the counseling profession (Burns, 2015; Kleist, 2018; Speciale & Goodrich, 2020). While counselor educators may have experience as counselors, they primarily work in academia, so their experiences do not authentically represent the needs of professional counselors. Counseling leaders need to represent and understand the people they serve: counselors. Therefore, this study sought to understand the lived experiences of master’s …

Objectification And Discrimination Among Bi+ Women: Body Image Outcomes And The Moderating Role Of Relationship Type And Partner Gender, Kaitlyn E. Ryan

Psychology Theses & Dissertations

Objectification theory posits that being sexually objectified by others leads to a greater likelihood of engaging in body surveillance behaviors, which in turn is associated with higher body shame (Fredrickson & Roberts, 1997). Prior research has identified both objectification and anti-bisexual discrimination as significant predictors of body surveillance and body shame among bi+ women (i.e., bisexual, pansexual, queer) (Brewster et al., 2014; Salim et al., 2024). No studies, however, have considered the unique experiences of romantically partnered bi+ women, including the potential moderating effects of partner gender and relationship type. The present study examined whether romantic relationships are protective for …

Microstructural And Thermal Studies Of Niobium On Copper Fabricated By Sputtering And Multicharged Ion Deposition, Md Obidul Islam

Electrical & Computer Engineering Theses & Dissertations

Niobium-coated copper (Nb/Cu) superconducting radiofrequency (SRF) cavities are a promising alternative to bulk niobium cavities for next-generation particle accelerators due to their reduced material cost and superior thermal conductivity of the copper substrate. However, cavity performance is fundamentally limited by the microstructural quality of sputtered Nb films and thermal transport across the Nb/Cu interface. Reduced thermal diffusivity in thin films and high interfacial thermal resistance contribute to localized heating and performance degradation under high RF fields. This dissertation addresses these challenges through a combined experimental and methodological investigation of thermal transport in Nb thin films, focusing on interface engineering using …
