Investigation Of A Flux Compression Magnetic Nozzle For Pulsed Plasma Propulsion, Zachary K. White

Dissertations

A key part of any propulsion system is how the energy of the propellants is used for thrust. Because of the high temperatures of nuclear fusion plasma, traditional methods like guiding the propellant with walls are not feasible, so instead, electromagnetic forces must be used to avoid physical contact between the propellant and the vehicle. Usually, to do so the physical nozzle is replaced by a magnetic nozzle where the physical walls are replaced by magnetic fields. This thesis focuses on the direct imaging and probe measurements of a laser produced plasma expanding into a magnetic field as analogous event …

A Hierarchical, Data-Driven Analytical Paradigm For Strategic Planning, Operational Decision-Making, And Resilience Enhancement In United States Electric Power Systems Under Extreme Demand Conditions, Anyama Hanson Tettey

Dissertations

Historical evidence indicates that the United States electric power grid continues to face persistent criticism for reliability challenges during peak demand conditions. Extreme ambient temperatures are a primary driver of such peaks, rendering the grid most vulnerable precisely when electricity demand is highest. These demand surges are largely driven by coincident operation of heating, ventilation, and air-conditioning systems across customer classes, a trend expected to intensify as sectors such as transportation increasingly rely on electrification. Efforts to mitigate demand related unreliability have traditionally focused on system-level demand forecasting and planning, typically at the scale of cities or entire utilities. However, …

Role Of Mkp-2 In Pancreatic Beta Cell Function & Development Of Diabetes, Nabin Ghimire

Dissertations

Diabetes mellitus is a chronic metabolic disease characterized by persistent hyperglycemia. Type 1 diabetes results from autoimmune destruction of β-cells, whereas Type 2 diabetes is associated with obesity and insulin resistance. Type 2 diabetes (T2D) and metabolic-associated fatty liver disease (MAFLD) are closely linked, as individuals with T2D are twice as likely to develop MAFLD. Previous work from our lab demonstrated that overexpression of MKP-2 in obesity promotes hepatic steatosis, diet-induced obesity, reduced insulin sensitivity, and increased body weight. However, the role of MKP-2 in the onset and progression of diabetes remains unclear. The objectives of this study were to …

Mechanisms Of Interface Formation In Bi-Metallic Components Fabricated Using Additive Manufacturing Processes, Michael P. Santangelo

Dissertations

As the expansion of metal additive manufacturing (MAM) brings forward new techniques and processes, compatibility between combinations of materials in multi-material components needs to be considered. Currently, the process by which compatibility between various metal alloys are evaluated is through laborious characterization of representative samples, which are products of both the additive manufacturing (AM) process used as well as the material chemistry. If a methodology for understanding the driving mechanisms behind formation of a compatible metallic interface can be created with the use of a predictive model, then wider implementation of multi-material MAM can be achieved. The objective of this …

Diffusion Behavior Of Uranium Fission Products In A Centrifugal Nuclear Thermal Rocket, Mitchell Schroll

Dissertations

Centrifugal nuclear thermal rockets (CNTR) are an advanced concept engine first proposed in the 1950’s that would allow for specific impulses of up to 1800 seconds. A major difference in this engine is that the liquid fuel allows for fission products to move through the fuel layer and even exit out of the reactor completely. This dissertation seeks to answer the question, how does the migration of fission products within a centrifugal nuclear thermal rocket affect its operation and performance?” To accomplish this a reduced order model was developed to simulate and track the fission products generated during the firing …

An Incremental Approach For Recovering Decompiled Variable Data Types Using Graph Neural Networks With Learned Confidence Estimates, Caleb Stewart

Dissertations

When software is compiled into machine code, the high-level data types defined in the original source code are lost. Binary type inference is the process of attempting to recover these high-level data types from compiled binary code. This dissertation investigates binary type inference using graph neural networks (GNNs) to predict data types for decompiled variables. The study is organized into three phases. Phase one presents DRAGON, a GNN model that predicts simple data types for decompiled variables using input graphs derived from decompiled abstract syntax trees (ASTs). DRAGON also produces confidence estimates indicating the degree of faith the model places …

Artificial Intelligence And Automated Decision-Making In Employment: The Future Of The Embattled Disparate Impact Theory Of Discrimination Under Title Vii, Daniel S. Alcorn

Journal of Law, Technology, & the Internet

Artificial intelligence now makes core employment decisions—from resume screening and video interviews to promotion and termination—yet Title VII’s disparate impact doctrine was built for paper tests, not black-box models. This Article argues that, while under attack by the Trump Administration and a minority of the U.S. Supreme Court, disparate impact remains indispensable but increasingly inadequate without adaptation. We show how algorithmic opacity frustrates causation, vendor delegation diffuses liability, predictive-accuracy claims distort “business necessity,” and trade-secret barriers impede proof of less-discriminatory alternatives. Drawing on emerging U.S. and comparative regimes, we propose a practical toolkit: (1) treat the algorithmic system as the …

Evaluating High-Strength Steel Welded Connections For Future Aws Welding Standards, Parker Minter

2026 Research Poster Competition

Welding plays a critical role in many civil engineering applications as it is a common method used to connect structural steel components. Because of how widespread the practice is, the American Welding Society (AWS) has developed a set of standardized welding guidelines to ensure consistent quality in structural welds. These standards allow common weld types to be fabricated using pre-approved procedures (e.g. welding materials, temperatures, and positions). Recently, high-strength structural steels have begun to be available domestically. Current AWS standards do not allow for high strength steels (yield strength greater than 80ksi) and need to be evaluated for the inclusion …

How Do Different Flight Training Programs Impact Pilot Proficiency?, Abigail Henson

2026 Research Poster Competition

The Federal Aviation Administration (FAA), founded in 1958, ensures safe and efficient use of national airspace by regulating aircraft and pilot certification, setting standards for airports, and managing the National Airspace System. One such regulation is in the certification process for aspiring student pilots. Students who want to obtain their private pilots license can do so by picking either a Part 61 or Part 141 flight school. While both lead to the same certification, these two options differ significantly in terms of structure; Part 61 programs offer flexibility with their individualized approach and fewer requirements while Part 141 schools follow …

Among different parts of aviation, general aviation (GA) stands out as one of its largest and most vital sectors. GA is defined as any civil aviation activity excluding scheduled commercial flights and military operations. While loss of engine power is a serious subset of general aviation accidents, accounting for more than 200 fatal accidents per year, several gaps remain in our current understanding of these accidents. While current literature includes older studies from 2000-2014, new data from the past decade have not been analyzed for trends yet. With this significant gap of more than a decade in understanding, it is …

Monitoring Eye Movements To Assess The Impact Of Sensory Feedback On Cognitive Workload During Myoelectric Prosthetic Hand Use, Naomi Tchoungang, Hailey Dirrigl, Justin Asbee

2026 Research Poster Competition

Modern prosthetic hands allow users to grasp and manipulate objects, but many users must constantly watch the device to complete even simple tasks. This heavy reliance on vision increases cognitive effort, slows movement, and makes prosthetic use feel less natural. An important question in prosthetics research is whether providing sensory feedback (enabling users to feel what the prosthetic hand is doing) can reduce this cognitive load and improve performance. In this study, sensory feedback refers to a system that provides clear tactile cues to the user upon contact between the prosthetic hand and an object, helping replace information normally felt …

Wild-type LRA-5, recovered from Alaskan soil samples, shares no more than 33% amino acid sequence identity with enzymes from pathogens like PER β-lactamases. Recombinant E. coli expressing wild-type LRA-5 and its engineered variants LRA-5^Y69Q and LRA-5^V166E showed MIC values equivalent to control strains. However, LRA-5^Y69Q/V166E displayed MICs above the resistant breakpoint for some β-lactams. Kinetic parameters correlated with the MICs, showing that the catalytic efficiency of LRA-5^Y69Q/V166E was comparable to those from class A β-lactamases, such as CTX-M-15, PER-2, and KPC-2. LRA-5^Y69Q/V166E exhibited k_cat/K_m values up to 11,000-fold higher compared to wild-type …

Exclusive By Design: Engineered Scarcity And Consumer Behavior In Fashion Drops, Caroline Meyer

2026 Research Poster Competition

The drop business model centers on releasing small batches of products, often without much notice, on a recurring or semi-regular schedule. These limited releases, or "drops," sell out quickly and rarely restock, creating urgency and making each product feel exclusive. Consumers are trained to anticipate launches, check for updates, and act fast within minutes to secure items before they’re gone. By tapping into psychological drivers such as scarcity, fear of missing out (FOMO), and the desire for social belonging, the drop model flips traditional retail logic. Instead of keeping shelves full, it withholds. Instead of lowering prices to drive sales, …

“The Influence Of Social Media And Algorithmic Capitalism On Popular Fiction”, Emma Bracken

2026 Research Poster Competition

In giving over literature wholly to the market, collapsing as far as possible the distance between literature’s residually sacral significance as a repository of higher values and its everyday function as a commodity, Amazon in one sense intensifies a phenomenon occasioned by the consolidation of publishing in recent decades into immense multinational media conglomerates,” writes professor Mark McGurl in his book, Everything and Less: The Novel in the Age of Amazon (2021). McGurl’s research on Amazon’s role in the literary industry created a baseline for my research on the use of algorithms in digital marketplaces as they relate to literary …

Assessing Mesenchymal Stem Cell Phenotype After Heparan Sulfate Supplementation, Isani Patel

2026 Research Poster Competition

Multiple sclerosis is an autoimmune disease that damages the protective coating of nerves, often causing lasting neurological symptoms. Current treatments slow disease activity but rarely repair existing damage. In response to this, a novel treatment option has emerged: mesenchymal stem cell (MSC) therapy. MSCs are cells found in different adult tissues like bone marrow, and they have the potential to release repair-supporting signals and moderate inflammation. Nevertheless, results in a clinical setting have been inconsistent due to variations in cell potency. As a potential strategy to enhance MSC therapeutic potential, the addition of heparan sulfate, a naturally occurring signaling molecule, …

Cardiovascular Monitoring For Maternal Health Using Wearable Devices, Daniela Alejandra Vasquez

2026 Research Poster Competition

Cardiovascular disease represents the leading cause of pregnancy-related mortality in the United States, accounting for over 30% of maternal deaths, with preeclampsia and hypertensive disorders contributing significantly to this burden. In Arkansas, maternal mortality rates reach 41.9 deaths per 100,000 live births. Current prenatal care relies on intermittent office-based blood pressure measurements conducted during 12-14 clinical visits, may not capture critical cardiovascular changes in a timely manner. Preeclampsia is characterized by new-onset hypertension after 20 weeks of gestation, affects 3-7% of pregnancies, and requires early detection to enable timely intervention. The limited accessibility of ambulatory blood pressure monitoring in rural …
