Halo: High Autonomous Low-Swap Operations, Sloan Hatter, Blake Gisclair

Mathematics and System Engineering Student Publications

Orbital object detection is a vital aspect of space operations, particularly for identifying satellite components. Convolutional Neural Networks (CNNs) are typically used for such operations by running onboard models directly on satellite systems. However, a new neural network architecture, known as Vision Transformers (ViTs), have shown greater effectiveness due to their ability to capture global context. One main issue of deploying systems with such capabilities is resource allocation. One solution is to run models on a Low-SWaP system; however, this results in inefficient performance. To enable efficient ViT operations on Low-SWaP systems, the model must be scaled down through quantization, …

A Practical Approach To Ir Policy Creation And Revision, Nicole R. Webber

University Libraries Publications

The process of policy development and revision often suffers reduced prioritization, particularly when staffing levels limit dedicated expertise and the time necessary for thorough evaluation. International surveys reveal common tendencies for institutional repository policies to lack desired degrees of comprehensiveness, refinement, or consistency, creating operational uncertainty and inhibiting long-term sustainability. This presentation addresses this pervasive gap, not by offering a case study or example documentation, but by introducing a structured, adaptable framework to guide policy development and maintenance, regardless of institutional size, platform, or maturity.

Drawing on a review of case studies and policy literature, a consolidated, openly licensed set …

Mississippi Coastal Bacterial Community Response To Lowered Salinty, Jackson C. Sues

Honors Theses

Microbial communities are essential to the function of coastal ecosystems; however, few studies have examined their response to short-term reductions in salinity. This study used a microcosm approach to examine how decreased salinity over five days affected seawater bacterial community composition, diversity, and richness. Microcosms were assigned to three treatments: unmanipulated seawater (control) collected from the Mississippi coast, seawater amended with natural freshwater, and seawater amended with sterilized freshwater. Length of time bacteria spent in the microcosms was found to have the strongest effect on bacterial community composition, while salinity effects were weaker but still statistically significant. All treatments shifted …

Ethnicity, Culture, And The Epidemiology Of Eating Disorders, Rebecca Atwell

Honors Theses

This systematic literature review addresses the research question: How does culture affect eating disorders? It examines the role of ethnicity and culture in shaping the prevalence, symptom presentation, and treatment of eating disorders across diverse populations. Although eating disorders have traditionally been studied in Western, predominantly White populations, growing evidence suggests that cultural norms, ethnic identity, globalization, and exposure to Western ideals significantly influence both the development and expression of disordered eating behaviors. Twenty peer-reviewed studies published between 2000 and 2024 were included. These studies were identified through systematic searches of PubMed, Scopus, Web of Science, and PsycINFO and selected …
