Environmental Impact Of Preventative Fire-Retardant Products On Soil Chemistry, Elisabeth Kraycik

Master's Theses

Human-caused ignitions account for most wildfires in the United States, particularly along roadsides, utility corridors, and other high-risk infrastructure where fine fuels are abundant and ignition sources are concentrated. These settings are often embedded within grassland and shrubland ecosystems, where fires spread rapidly and can threaten nearby communities and assets. Preventative fire-retardant products (PFRPs) have emerged as a promising strategy for reducing ignition likelihood in these environments. Unlike traditional aerial retardants applied during active suppression, PFRPs are designed for annual, pre-season application to ignition-prone locations. Despite their growing use, the environmental consequences of repeated PFRP applications remain poorly understood, especially …

Assessing Video Game Pedagogy For Civil Engineering Education And K-12 Stem Engagement, Jillian Codron, Anahid A. Behrouzi

Architectural Engineering

Traditional civil engineering education is often structured around a “theory before practice” model, where students first learn concepts in lecture and then confirm them in a laboratory setting.

Exploring Border Rhetoric, Resistance, And The American Dream: Alexandria Ocasio-Cortez' First House Address, Candice L. Ruh Phd, Cassandra Hightower

Feminist Pedagogy

Border rhetoric can be a “muddy” topic for undergraduates, as borders are often taught as fixed, factual lines that divide places and people. However, from a communication perspective, borders are fluid, symbolic, and socially constructed. This difference between viewing borders as physical dividers versus rhetorical constructs creates a valuable opportunity for students to think critically about how meaning is shaped by borders of land, language, and identity.             This original teaching activity uses Representative Alexandria Ocasio-Cortez’ (D-NY) first House speech—the most-watched C-SPAN video within 12 hours of release (Gajanan, 2019)—as a central case. It invites students to analyze a key moment …

Vlsi Spike Encoder For Spiking Neural Networks With 4-Bit Sar Adc, Jack Marshall, Wyatt Tack, Cameron Young, Ryken Thompson

Electrical Engineering

A spike encoder forms the interface between sampled data, such as image data or a sensor signal, and a spiking neural network by converting numerical input samples into discrete spike events. Unlike conventional artificial neural networks, spiking neural networks use spare, even-driven computation instead of continuous-valued activations. This makes them attractive for low-power embedded systems, biomedical electronics, and other edge applications where energy consumption, physical area, and thermal limits are important design constraints.

This project develops a modular spike encoder architecture for spiking neural networks with selectable support for temporal, rate, multi-spike, and delta encoding. Prior work has shown that …
