Microscopy Investigations Assessing The Dispersion Within Particle Composites Manufactured In An Acoustic Levitator, Matthew Smith

Student Research Symposium (SRS)

Acoustic levitation offers a containerless environment for studying the ultraviolet (UV) curing of particle composites to support goals for in-space manufacturing. In this study, samples composed of a photopolymer resin mixed with alumina or regolith powders were prepared as slurries. Acoustic levitation was used to suspend the droplets during UV exposure, enabling curing without contact with a container or mold. Optical microscopy studies reveal the effect of the contactless manufacturing process on particle dispersion. The study demonstrates that acoustic levitation shows potential as a contactless environment for investigating the manufacturing of particle composites relevant to in-space and microgravity manufacturing environments.

A Low-Complexity Generator Matrix-Influenced Algorithm To Globally Recover Algebraic Codes Over Finite Fields, Oshani Jayawardane

Student Research Symposium (SRS)

Code Recovery using algebraic-geometric approaches becomes computationally expensive with the cardinality of the field and complex code structures. In response, we propose a low-complexity algorithm that utilizes structures in algebraic-geometric codes over finite fields. The low-complexity algorithm to locally recover algebraic codes over finite fields (i.e., 𝑙𝑟𝑐 algorithm) is defined based on a sparse matrix factorization that computes the inverse of an (r+1) x r generator matrix, whose elements are defined by the points on the surface in P³ over the finite field 𝔽q with locality r. We have shown that the (𝑙𝑟𝑐 algorithm) reduces the complexity from O(n³) to …

Events such as the large-scale blackout in Spain (April 2025) and the Heathrow power disruption (2025) illustrate how local perturbations can cascade into systemic breakdowns. Traditionally, system behavior was governed by centralized operators who had exclusive access to the analytical tools and data required to understand grid …

Crew Resource Management Analyzed In Guyana Military Accident, Kaylee Lall

Student Research Symposium (SRS)

"In December 2023, a Guyana Defence Force Bell 412EP helicopter crashed in mountainous jungle terrain near the Venezuela border, killing five of the seven personnel on board. Preliminary investigation findings indicate the probable cause of the accident was pilot error, rather than mechanical failure. Due to deteriorating weather conditions, the crew deviated from the standard route and elected to fly under visual flight rules (VFR) along the Mazaruni River. The combination of limited visibility, rising mountainous terrain, and potential spatial disorientation likely contributed to this controlled flight into terrain.

This case study applies the SHELL model to analyze the interactions …

Development Of A Planar 3-Dof Multi-Agent Apriltag Localization System With Predictive Track Recovery Under Intermittent Detection Loss, Timothy Mascal

Student Research Symposium (SRS)

Research into multi-agent swarming leverages multiple low-cost agents to perform tasks resulting in a more resilience, scalable, and efficient systems compared to systems using single agents. To support research on multi-agent swarming, there is a need for a low-cost system that reliably localizes multiple agents moving on a plane in three degrees of freedom (x, y, yaw). Existing approaches utilize an overhead camera with fiducial markers to perform localization but suffer performance degradation when agents undergo maneuvers featuring fast rotations and translations. The induced motion blur causes intermittent detection loss. This work proposes a localization system that maintains agent localization …

Investigation Of Biofilm Formation And Osmotic Stress Tolerance Of Nonmotile E. Coli Mg1655 In Simulated Microgravity, Tyler Jenkins

Student Research Symposium (SRS)

Simulated microgravity presents multiple physiological stressors for astronauts, including bone demineralization, muscle loss, and weakening of the immune system (Chavez et al., 2024). Bacteria serve as viable model organisms to study physiological changes because of their abundance in the human digestive system and skin. Motility in bacteria plays a significant role in cell survival, but few studies have been conducted on microgravity’s effect on motility phenotypes. While motile strains like K12 have been studied extensively under microgravity conditions (Topolski et al., 2022; Chavez et al., 2024), the effects of simulated microgravity on non-motile strains are largely unknown. To better understand …

Growing Plants On The Moon: How Mizuna Roots And Organic Matter Spark Microbial Metabolism, Stefani Capasso Villanueva, Nupur Kulkarni

Student Research Symposium (SRS)

Establishing functional plant–microbe systems in extraterrestrial substrates is critical for sustainable lunar agriculture. We tested whether manure amendment and Mizuna mustard (Brassica rapa var. japonica) rhizosphere activity enhance the metabolic potential of a lunar regolith simulant (LHS-1). Plants were grown in four treatments: Unplanted manure-amended regolith (LRM), planted manure-amended regolith (LRMP), planted unamended regolith (LRP), and soil controls. Plant height and community-level physiological profiles (CLPP; Biolog EcoPlates) were measured to assess growth and metabolic diversity. Mizuna grew best in soil, with modest improvements in LRMP compared to LRP, though regolith treatment differences were not statistically significant. CLPP revealed the highest …

Examining Self-Direction In Learning Programming Among First-Year Students, Abigail Blalock

Student Research Symposium (SRS)

In this poster, we present empirical insights into first-year students’ self-direction in learning programming. In this study, we use a 25-item Personal Responsibility Orientation to Self-Direction in Learning Scale (PRO-SDLS) to assess the self-direction of first-year students in learning programming. The PRO-SDLS is comprised of 4 constructs: self-efficacy, initiative, motivation, and control. Additionally, this study examines the results of the PRO-SDLS across different demographic groups (i.e., first-generation, students with employment, financial aid, etc.). A pre- and post-survey was administered during the Fall 2024 semester in an introductory programming course for first-year engineering students. Data was collected from seven course sections, …

Evidence For Robustness Of Synchronous Hatching Consensus Algorithm: Examining New Model Parameters And New Fault Types, Grace Gratton, Morgan Kendall

Student Research Symposium (SRS)

Robustness to faulted agents in consensus algorithms within a multi-agent system is a critical requirement for reliable systems. Faulted agents can compromise the swarm, leading to catastrophic consequences, including economic impacts and possible loss of life. Therefore, it is critical to develop robust consensus algorithms to ensure the security and reliability of the systems we rely upon. Biologically Inspired Design previously led to the Synchronous Hatching Consensus Algorithm, which was robust up to 20% faulted agents reporting false positives, but not robust to faulted agents reporting false negatives. This work builds upon the previous model by increasing robustness to both …

Paschen Curves Of Glow Discharges In Different Gas Compositions, Seth Gerow

Student Research Symposium (SRS)

Our work focuses on low current, low temperature plasma discharges: glow and corona. Townsend theory predicts that the critical voltage to initiate a gas breakdown (i.e., a "spark") between two parallel plate electrodes is dependent on the product of the pressure and distance; consequently, variations in either parameter which results in the same product, pd, do not affect the breakdown voltage. In this work, we present Paschen curves of narrow-to-wide electrode glow discharges in two gas mediums, argon and air. These curves show a deviation from theoretical predictions, such that changes in electrode configuration create a uniform shift of the …
