  • Dissertation Defense: What’s In A Frame? Exploring State Policymakers’ Conceptualization Of Human Trafficking.

    Virtual

    Human trafficking within and across nations is a pervasive, insidious global criminal enterprise that endangers human rights and impedes social justice. Sex and labor are two fundamental types of human trafficking, but both media and policies prioritize the former. Social work calls for empowering marginalized groups, and labor trafficking survivors—who are more likely to be women and immigrants of color—certainly …

  • Thesis Defense: Multi-Species Time Histories During Oxidation of Ammonia Hydrogen Blends at High Pressures Inside a Shock Tube

    Virtual

    Emissions of greenhouse and toxic gases from current combustion processes significantly contribute to the global climate crisis. Recent policies worldwide have shifted focus towards combating these emissions using clean and renewable energy sources. However, achieving carbon neutrality while meeting modern energy needs will require alternative carbon-free fuel sources for power generation turbine cycles. Ammonia-hydrogen blends have shown potential as carbon-free …

  • Thesis Defense: The Impact of Experience Replay Buffers on Catastrophic Forgetting within Proximal Policy Optimization

    L3Harris Engineering Center: HEC 356

    Catastrophic Forgetting continues to be a prevalent issue for any neural-based approach to learning. Without better understanding and solutions to solving catastrophic forgetting, learning performance and efficacy in autonomous agents, particularly deep learning-based agents will become drastically hindered. Current literature contains approaches to reduce the effects of catastrophic forgetting via task decomposition, rehearsal, and layered learning. However, critical agent knowledge …

  • Dissertation Defense: Advanced Optical Diagnostic Techniques for Heat Transfer Measurements in Supercritical CO2 Flows

    TA: 103 and Virtual

    Supercritical CO2 (sCO2) has been proposed for a plethora of applications, such as power generation, air conditioning, and thermal management of electronic equipment. In proximity to critical conditions, the thermal and transport properties of the CO2 vary abruptly, promoting a significant heat transfer enhancement. Revealing the heat transfer processes associated with CO2 flows requires measuring fluid temperature, pressure, heat transfer …

  • Dissertation Defense: High-Pressure Natural Gas and Methane Experiments and Modeling at Rocket Thrust Chamber Conditions

    Virtual

    In recent years, the space travel industry has grown exponentially, resulting in the need for a low-cost, efficient rocket engine fuel. As such, there has been renewed interest in utilizing liquid natural gas (LNG) as it is less likely to soot than kerosene-based fuels and has widespread availability and low cost of use as compared to the traditional RP-X and …

  • Dissertation Defense: Improving Osteological Sex Estimation Methods for the Skull: Combining Morphological Traits and Measurements Utilizing Decision Trees and Random Forest Modeling

    HPH: 409M

    The purpose of this research was to improve osteological sex classification accuracies for the skull by combining morphological and metric variables into multiple models using decision trees and random forest (RF) modeling. The sample was derived from four U.S. based skeletal collections and consisted of 403 individuals of European American and African American population affinities. Twenty-one morphological traits and 21 …

  • Dissertation Defense: DECENTRALIZED OPTIMIZATION ALGORITHMS FOR COORDINATION OF POWER GRID AND OTHER CRITICAL INFRASTRUCTURES

    Virtual

    Critical infrastructures such as power grids, transportation networks, water systems, and others increasingly interact with each other for functional facilities. Therefore, coordinating these interdependent critical infrastructure networks has become paramount for synergistic operation. Since different infrastructures belong to different entities, this dissertation proposes decentralized optimization algorithms tailored to various coordination challenges. First, this dissertation proposes a decentralized framework for coordinating …

  • Thesis Defense: Safety Testing for Hydrogen and Hydrogen-Natural Gas Mixtures for De-carbonizing Electric Power Plants

    Mathematical Science Building: 149

    The successful transition to global clean energy is contingent upon meeting the increasing worldwide energy demand for power while simultaneously curbing greenhouse gas emissions. This study delves into the complexities of transitioning to cleaner energy sources and the challenges posed by utilizing hydrogen and hydrogen/natural gas mixtures as a potential fuel source alternative to traditional carbon-based combustion cycles. By addressing …
