Haptics Based Grasping Of Novel Objects Using Robotic Manipulator, Nicolas C. Leocadio

Graduate Thesis and Dissertation post-2024

This work is focused on extending and demonstrating the generalizability of previous interactive perception-based work done on a model-free, non-neural algorithm for robotic gripper envelopment of objects using haptic feedback. Using a 6-axis force and torque sensor placed behind the wrist of a robotic arm's manipulator, appropriate motions are generated in order to achieve contact with, align the manipulator with, and place the manipulator around some desired object in a position where grasp is possible by simply closing the manipulator. The algorithm relies on generating restoring (reactive) and frictional forces by rapid multidirectional oscillation of gripper fingers about an initial …

Enhancing The Hardness Of The Multispectral Zns Transparent Ceramics Through Ga2s3 Incorporation: A Comparative Study Of Vapor Transport Deposition And Solid-Solid Reaction Methods, Hayat Soufiani

Graduate Thesis and Dissertation post-2024

Multispectral zinc sulfide (MS-ZnS) is an important optical ceramic widely used in broadband imaging systems due to its wide transmission range and relatively low cost. However, its modest mechanical properties limit its durability in harsh environments. This dissertation investigates two solute strengthening methods, vapor transport deposition (VTD) and diffusion coupling (DC), to enhance the hardness of MS-ZnS windows through Ga2S3 incorporation while maintaining optical transparency. The VTD process successfully incorporated gallium in the subsurface, resulting in up to 120 % increase in microhardness compared to untreated samples, but with slight discrepancies in lateral gallium distribution. The DC technique demonstrated superior …

A New Dawn Of Joy: How Joy Is Cultivated Among Black Transgender And Nonbinary Young Adults In Florida, Courtney Marciá Gardner

Graduate Thesis and Dissertation post-2024

The state of Florida had a record-breaking number of implemented and proposed policies between 2023-2024 that impacted transgender and nonbinary individuals. Black transgender and nonbinary people are particularly impacted by these policies due to the compounded effects of their race and gender identity. Nonetheless, despite the growing literature on Black transgender and nonbinary individuals, a lack of research exists examining positive aspects of intersectional experiences among Black transgender and nonbinary individuals. This qualitative study shifts away from deficit centered frameworks by investigating how Black transgender and nonbinary young adults in Florida cultivate joy in their lives. This study uses a …

Mechanistic Insights Into The Antimicrobial Action Of Fungus-Derived Xanthoquinodins Against Clostridioides Difficile, Erika A. Serravalle

Graduate Thesis and Dissertation post-2024

The bacterial pathogen Clostridioides difficile is the leading cause of antibiotic- and healthcare-associated diarrhea, imposing significant clinical and economic impacts. The emergence of hypervirulent strains, such as PCR ribotype 027 (RT027), has exacerbated disease severity, recurrence rates, antibiotic resistance, and epidemiological spread. Expanding resistance profiles among C. difficile strains continue to limit the effectiveness of current IDSA-SHEA recommended therapies, which are already compromised by high recurrence rates due to antibiotic-induced disruption of the gut microbiota. These challenges highlight the urgent clinical need to identify and characterize antimicrobial compounds targeting alternative pathways in C. difficile physiology. We report the discovery and …

On High-Speed Breakup Of Water Droplets Behind High Mach Number Shocks, Sydney M. Briggs

Graduate Thesis and Dissertation post-2024

Water droplet breakup in high-speed flow is a relatively popular experimental study to analyze breakup mechanisms. There is a plethora of experiments performed at low Mach number and low Weber number, but studies with higher speed flows and higher Weber numbers are less common. In this study, water droplet breakup is assessed using high-speed shock waves (Mach 2.3-above Mach 5) in a shock tube. Multiple methods are used to introduce droplets, and multiple different water purity levels are considered. An assessment was made into whether cavitation played a role in the breakup process physically, as this has been a budding …

This thesis explores the manifestation of racism, sexism, and capitalism in the language and rhetoric of sports media through a case study of WNBA players Angel Reese and Caitlin Clark. This study theorizes that sports media has referred to Reese and Clark with damaging language tied to the intersections of their respective identities. This thesis also identifies and analyzes the presence of repeated themes throughout select sports media that mirror relevant theories surrounding stereotypes, biases, and marginalization in sports. Examining and analyzing the subtle nuances at play allows one to understand how language implicitly reinforces harmful narratives and, thus, how …

A Kinder Panopticon? Examining Effects Of Fairness And Justice On Performance Outcomes Under Advanced Electronic Monitoring Systems, William F. Tang

Honors Undergraduate Theses

The adoption of Electronic Performance Monitoring (EPM) systems has increased with the prevalence of remote workers post-COVID. Research indicates EPM yields conflicting performance and behavioral outcomes. EPM-related behavior can be predicted by organizational justice (the extent to which workplaces are perceived as fair in nature); environments with higher justice ratings are less likely to induce issues like stress and distrust. However, advanced EPM like electroencephalograms (EEG) may modulate the relationships between perceived fairness, stress, and work performance. This study assigned 42 participants to a modified vigilance test (based on Temple, et al., 2001), which participants took under 3 placebo monitoring …

0th Order Solutions Of The Wavefunctions For The Quantum Elliptical Box And Microstrip Antenna, Nishtha Tikalal

Honors Undergraduate Theses

For a quantum particle confined to a two-dimensional elliptical box or electromagnetic wave in a microstrip antenna, geometrical and boundary condition interplay result in a spectrum of spatial patterns. Due to the asymmetrical nature of the ellipse, we are faced with continuous symmetry reductions, leaving both degenerate and nondegenerate solutions. Here, we present a complete derivation of an analytical solution and visualizations of the fundamental wavefunctions for both Dirichlet and Neumann boundary conditions respectively corresponding to the quantum elliptical box and the elliptical microstrip antenna.

We demonstrate that the eigenmodes, governed by eccentricity, directly correspond to the modal field distributions …

Effects Of Invigorating And Relaxing Music On Heart Rate, Blood Pressure, And Heart Rate Variability, Matthew Joshua Faur

Honors Undergraduate Theses

Heart-rate variability (HRV) has been documented to correlate with several health measures, including autonomic nervous system longevity and athletic performance (Zulfiqar, 2010). While increasing age does not affect heart rate, there is a steady decline in HRV, which is a biological marker of aging and the decline of autonomic nervous system function. Furthermore, men who exercise regularly tend to have increased HRV, suggesting a mitigation of the typical age-dependent loss of HRV (Kristal-Boneh et al., 1995). Previous studies have suggested that music may have a physiological effect (e.g., fluctuating vitals, emotional changes) on cardiovascular parameters. However, little is known about …

Impact Of Tgf-Β And Twist1 On Motility And Proliferation In Estradiol-Treated Mcf-7 Tamr Cells In-Vitro, Thomas L. Scott Iii

Honors Undergraduate Theses

Breast cancer is a highly malignant cancer and is known to be grouped into three main types: adenocarcinoma, invasive ductal carcinoma (IDC) and ductal carcinoma. Breast cancer commonly arises as adenocarcinoma, located in the milk ducts, and becomes IDC when it spreads into the surrounding tissue from the influence of cytokines and hormones. This study outlines the rate of proliferation and motility of a type of adenocarcinoma, MCF-7-TamR, to become invasive ductal carcinoma when Twist1 is downregulated and exposed to TGF- and estradiol (E2) in-vitro. We hypothesize that the downregulation of Twist1 will reduce cell adhesion and cytoskeleton proteins …

The Inverse Scattering Transform For The Nonlinear Schrödinger Equation, Ivan Casas-Rocha

Honors Undergraduate Theses

The Nonlinear Schrödinger (NLS) Equation, iψ_t + 1/2 ψ_xx ± |ψ|²ψ = 0, is a nonlinear partial differential equation which is used to model several physical phenomena including nonlinear effects inside optical fibers and the formation of rogue waves in shallow water. It is particu- larly difficult to study solutions to this equation due to the nonlinearity, and the nonlinearity leads to incredibly interesting solutions not found in linear PDEs such as solitons. In this thesis, we highlight two methods of obtaining solutions to the (NLS) equation: the Inverse Scattering Transform and the Dressing Method. Furthermore, …

Investigating The Effects Of A Psychoplastogen On Depressive-Like Behaviors In Huntington Disease Model Mice, Kaleigh M. Hanley

Honors Undergraduate Theses

Huntington Disease (HD) is a neurodegenerative disorder caused by an expansion in the trinucleotide CAG repeat on exon 1 of the huntingtin gene. In HD one of the first symptoms is often depression. In cases where SSRIs fail, treatments for treatment-resistant depression often become a patient’s only option. These rigorous treatments, such as electroconvulsive therapy, are not suitable for this patient population as it can worsen motor symptoms. In order to search for potential alternatives, we queried whether depressive-like behavior could be reduced in Hu97/18 and Q175FDN HD mice by administering tabernanthalog, a non-hallucinogenic psychedelic analog. Our study is not …

Honors Undergraduate Theses

This thesis addresses the long-standing absence of community archaeology initiatives in the Kurdistan Region of Iraq by designing and implementing a pilot public archaeology program at the site of Kurd Qaburstan, a large Middle Bronze Age city (ca. 1800 BCE) located on the Erbil Plain. In summer 2024, the author implemented a community archaeology activity designed as a first step toward sustained engagement with the village that partially overlaps the site. The program—a hands-on lesson in archaeological stratigraphy for K–5 students, followed by a guided site visit—was intentionally simple, affordable, and easy to carry out alongside ongoing fieldwork. The activity …

Comparative Efficacy Of Hallucinogens In Treating Mood Disorders Through A Meta-Analysis Of Symptom Reduction, Dosage, And Duration, John Marco D.F. Muniz

Honors Undergraduate Theses

Background: Hallucinogens including psilocybin, lysergic acid diethylamide (LSD), ketamine, N,N-dimethyltryptamine (DMT) (as ayahuasca), have re-emerged as potential rapid-acting treatments for mood disorders. We conducted a meta-analysis of placebo-controlled trials evaluating their efficacy in depression and anxiety disorders. Methods: A systematic review identified 12 trials (Total ≈ 670) meeting inclusion criteria (randomized, placebo-controlled). Data on Cohen’s d and Hedges’ g effect sizes for depression- and anxiety-related outcomes were extracted. We computed pooled effect sizes (weighted by sample size and inverse variance), performed subgroup analyses by drug, diagnosis, follow-up duration, and outcome measure type, and assessed heterogeneity (I², Q …

Effect Of Metal Ions On The Reactive Oxygen Species Scavenging Capabilities Of Cerium Oxide For Biological Applications, Agastya Mittal

Honors Undergraduate Theses

Ceria nanoparticles' capabilities to defend cells against oxidative stress through superoxide dismutase activity are well-documented. Ceria nanoparticles demonstrate a ratio between 3⁺/4⁺ oxidative states on the surface of the particles to exhibit oxygen vacancies, a feature that allows these particles to scavenge Reactive Oxygen Species (ROS) in times of Oxidative Stress. Oxidative stress arises from many wounds in the body, such as wounds in the skin, and can have significant impacts on the health of an individual. Even when receiving treatment for the skin wound, ROS can circulate from around the wound, be generated from an imbalance …
