Damping Modulation Of Dampened Kapton Surfaces, Sebastian Esteban Jan 2025

Damping Modulation Of Dampened Kapton Surfaces, Sebastian Esteban

Honors Undergraduate Theses

When droplets are vibrated or disturbed, they can exhibit a complex sloshing motion, an understudied behavior in drop physics. Droplet sloshing involves a complex combination of transverse and longitudinal motion that changes the droplet's effective weight on the surface the droplet is on. Our current understanding stems from preliminary work focusing on a cantilever beam of fixed thickness and variable viscosity of the liquid being sloshed. This investigation will focus on how variable cantilever thickness and constant viscosity for a liquid being sloshed affects the beam's deflection under consistent vibration. It will also investigate how the natural frequency of a …


Integrated Compliant Structure For A Hand Exoskeleton, Tristan R. Koopman Jan 2025

Integrated Compliant Structure For A Hand Exoskeleton, Tristan R. Koopman

Honors Undergraduate Theses

This thesis presents the design and prototyping of a wearable hand exoskeleton that integrates a flexible structural framework to assist with hand movement while maintaining comfort and anatomical conformity. The goal was to create a device that supports tendon-driven actuation through a compliant structure, combining elements of rigidity and flexibility to match the natural geometry and motion of the human hand. Traditional hand exoskeletons often trade off motion for structure or vice versa. This project aims to bridge that gap with a hybrid compliant design that balances flexibility and support. The design process followed an iterative approach involving rapid prototyping …


Fabricating Silver-Ceria Polymer Nanocomposite Scaffolds For Biomedical Therapeutic Applications, Shreya S. Pawar Jan 2025

Fabricating Silver-Ceria Polymer Nanocomposite Scaffolds For Biomedical Therapeutic Applications, Shreya S. Pawar

Honors Undergraduate Theses

Improper healing of bone fractures and limited regeneration of bone following bone tumor resection remain a prevalent complication worldwide. Long-term effects of this include joint instability, limited movement, and arthritis. Bone infections (osteomyelitis), reactive oxygen species (ROS) generation via excessive inflammation, and underlying conditions such as osteoporosis can contribute to suboptimal bone tissue regeneration. ROS accumulation stimulates osteoblast apoptosis, while promoting osteoclast differentiation. These processes inhibit mineralization and osteogenesis. Conventional therapeutics involve the utilization of drugs and bone grafts. However, these approaches pose limitations and can result in subsequent complications. Microbial infections, ROS accumulation, and excessive inflammations are factors that …


Self-Compassion And Shame: The Role Of Socioeconomic Status, Amanda Louie Jan 2025

Self-Compassion And Shame: The Role Of Socioeconomic Status, Amanda Louie

Doctor of Psychology (PsyD)

Undergraduate student mental health concerns are a growing issue on a global scale. One proposed intervention to support student well-being is to increase student self-compassion. Previous research has found that self-compassion can decrease negative affect and shame, and improve well-being and resilience, which in turn may reduce stress. A lesser area of study concerning self-compassion is what effect, if any, socioeconomic status may have on the development of self-compassion in individuals. To address this gap in the literature, this study collected data from college students on the West Coast and used a correlational design to explore the relationships between self-compassion, …


Utilization Of Assessment Results To Improve Identification Of Prenatal Substance Exposure, Whitney R. Mendenhall Jan 2025

Utilization Of Assessment Results To Improve Identification Of Prenatal Substance Exposure, Whitney R. Mendenhall

Doctor of Psychology (PsyD)

Prenatal substance exposure (PSE) significantly increases the risk of behavioral, emotional, and neurological challenges in children (Eiden et al., 2023). Children with PSE present similarly to children with attention deficit hyperactivity disorder (ADHD) and are often diagnosed with ADHD due to shared symptomatology (Garrison-Desany et al., 2022). However, PSE has a greater association with long-term cognitive, emotional, social, and behavioral deficits (Eiden et al., 2023). While PSE and ADHD share similar symptomologies, treatment and outcomes vary substantially, where early identification and treatment is a critical protective factor against the development of other psychological conditions in children with PSE. PSE can …

An Ailment I Will Fight With: Differential Diagnosis And Methodology Evaluation Of Possible Treponemal Infection At Dayr Al-Barsha, Egypt, Lindsey D. Lefebvre

Graduate Thesis and Dissertation post-2024

Treponemal diseases, including bejel, yaws, pinta, and venereal syphilis, have long plagued human populations and continue to pose public health challenges today. Despite their persistent global presence, the origins, transmission pathways, and archaeological identification of these diseases—caused by various subspecies of Treponema pallidum—remain contested. This study explores the utility of standardized diagnostic criteria, as proposed by Baker et al. (2020), in assessing the presence of treponemal disease in highly fragmentary skeletal remains from the Roman-period necropolis at Dayr al Barsha, Egypt. Through the examination of 14 individuals, this research seeks to (1) identify indicators consistent with bejel (T.p. …

Contagion Chronicles: A Spatiotemporal Analysis Of Armed Conflict And Infectious Disease, Devyn Escalanti Jan 2025

Contagion Chronicles: A Spatiotemporal Analysis Of Armed Conflict And Infectious Disease, Devyn Escalanti

Graduate Thesis and Dissertation post-2024

This dissertation examines the relationship between armed conflict and infectious disease transmission through a novel theoretical framework that integrates ecological disturbance and health systems resilience theories into epidemiological contexts. The framework conceptualizes diseases along a continuum from "pulse" to "press." Pulse diseases, like Ebola, are characterized by sudden onset, high mortality, and short-term outbreaks. Press diseases, like HIV, progress gradually with lower mortality and long-term persistence. Grounded in this pulse–press disease typology and ecological and health systems resilience, the theory suggests that the absorptive capacity, adaptive capacity, and resilience of community health workers in conflict areas can influence disease transmission, …


Shock Tube Investigation And Chemical Kinetic Modeling Of Green Propellants For Space Missions, Marley Albright Jan 2025

Shock Tube Investigation And Chemical Kinetic Modeling Of Green Propellants For Space Missions, Marley Albright

Graduate Thesis and Dissertation post-2024

Hydrazine thrusters have been used for decades to land spacecraft on other planets. While its use is common, handling hydrazine is difficult due to its toxicity; this poses a risk to humans during testing and loading the propellant onto a spacecraft. Occupational Safety and Health Administration has limited human exposure to 1 part per million (ppm) of hydrazine per eight-hour workday. Green propellants are promising alternatives because they have lower toxicity but do not sacrifice performance. Green propellant technology has been demonstrated in space and future missions are planned, such as NASA’s Green-Propulson Dual-Mode technology demonstration. At the University of …

Addressing Vulnerabilities And Defesne Mechanisms In Transformer-Based Language Models, Mansour Al Ghanim Jan 2025

Addressing Vulnerabilities And Defesne Mechanisms In Transformer-Based Language Models, Mansour Al Ghanim

Graduate Thesis and Dissertation post-2024

Transformer-based Large Language Models (LLMs) have achieved remarkable success across Natural Language Processing (NLP) tasks, yet their increasing adoption has exposed critical vulnerabilities across input, model, and output layers. This dissertation systematically investigates these vulnerabilities and develops corresponding defenses, offering an end-to-end view of LLM security. First, we study model-level vulnerabilities through backdoor injection attacks that implant hidden malicious behaviors via hardware perturbations. We propose TrojBits, a hardware-aware attack that uses minimal bit-flips to insert trojans into models. Its three-stage design—Vulnerable Parameter Ranking, Hardware-Aware Attack Optimization, and Vulnerable Bit Pruning—success- fully compromises BERT and XLNet using only 64 parameters and …

Aluminum Alloys For Laser Powder Bed Fusion Additive Manufacturing And Process Optimization By Machine Learning, Kevin Graydon Jan 2025

Aluminum Alloys For Laser Powder Bed Fusion Additive Manufacturing And Process Optimization By Machine Learning, Kevin Graydon

Graduate Thesis and Dissertation post-2024

Laser powder bed fusion (LPBF) additive manufacturing is a promising manufacturing technology enabling enhanced design freedom through layer-by-layer production. However, traditional, wrought aluminum (Al) alloys suffer from solidification cracking during LPBF processing and the initial printer parameter optimization process required for every novel or untested material is time and resource intensive. There exists a need to formulate Al alloys for LPBF and a method to reduce the resources consumed during initial printer parameter optimization studies. Al-9.5Ce-xMo (x = 0.2, 0.6, 1.0 wt. %) alloys have been designed specifically for LPBF utilizing the CALPHAD approach. Additionally, a neural network model was …

Under New Management?: Sovereign Wealth Funds And Their Ownership Of U.S. Sports Teams, Benjamin K. Moyer Jan 2025

Under New Management?: Sovereign Wealth Funds And Their Ownership Of U.S. Sports Teams, Benjamin K. Moyer

Dickinson Law Review (2017-Present)

In October 2021, Saudi Arabia’s sovereign wealth fund (“SWF”) successfully purchased the English Premier League soccer team Newcastle United F.C. for $400 million. With this transaction, Saudi Arabia joined fellow Gulf countries, Qatar and the United Arab Emirates, in owning a major European soccer team through one of its state’s SWF. States have long used their SWFs to invest in foreign markets, but recent trends have transformed these originally strictly financial vehicles into political tools. Since the 2007–2008 financial crisis, many states have used their SWFs not only to produce financial gains but also to generate soft power through political …
