Bridging Gaps With Occupational Therapy: The Unique Role Of Occupational Therapy In Women’S Day Shelters, Alex Sato

Doctoral Projects

Homelessness is a multifaceted, complex issue that we face as a society. Mainstream services provided to homeless or vulnerable populations tend to focus on housing and basic services. While these are essential and meaningful, literature suggests there is a lack in trauma and self-care support (Marzana et al., 2023; Milaney et al., 2020). Looking through an Occupational Therapy (OT) lens, there are a multitude of ways the profession can provide holistic care. Current OT service provision within this population most commonly focuses on obtaining and maintaining housing and addressing the survival occupations these individuals may be engaging in (Cunningham & …

Promoting Participation And Self-Efficacy Among Youth With Disabilities In Community-Based Vocational Education, Allison Hollender

Doctoral Projects

Occupational therapy, with its focus on participation, contextual adaptation, and strength-based practice, is uniquely suited to support the growth and inclusion of youth in transition (Angell et al., 2018; Cahill et al., 2020; Carroll et al., 2025). Research indicates that transitional-aged youth (TAY) with disabilities, ages 14-24, are less likely to graduate from high school, pursue postsecondary education, or live independently (BLS, 2024; Cheng & Shaewitz, 2022; Cook et al., 2015). These disparities are compounded by occupational deprivation, or limited opportunities for meaningful participation, which can negatively impact long-term self-efficacy and belonging (Arbesman & Logsdon, 2011; Cahill et al., 2020). …

Homomorphically Encrypted Faceted Values, Tanmay Singal

Master's Projects

Faceted values prevent the implicit flow of sensitive information by controlling the visibility of program data. They achieve this by maintaining two facets for each variable: a public facet, which is observable, and a private facet, which remains hidden. Although this method secures the flow of sensitive data, it can be leaked if the server storing the faceted values is compromised. While faceted values may be encrypted on the server, doing so would necessitate that the private facets be briefly decrypted during execution to allow arithmetic operations to be performed on them, creating an attack vector for information to be …

Ai-Enabled Anticipatory Handover Predictions In 5g Networks, Ojas Ankush Naik

Master's Projects

As users move across network cells in 5G, it is critical to maintain seamless connectivity through efficient and fast handovers. However, as 5G networks have a very dense deployment of cells and higher carrier frequencies, handovers are often more frequent and challenging, leading to failures or the ping-pong effect. In this research, we are going to use Artificial Intelligence (AI) techniques to enable predicting handover(HO) events proactively as opposed to reactively, aiming to reduce HO failures and unnecessary handovers. We develop Long-Short-Term Memory (LSTM) and Bidirectional LSTM (Bi-LSTM) models to forecast future signal measurements, predict handover trigger points, and compare …

Simple Vs. Complex Human Activity Classification Via Hybrid Machine Learning Models, Anusha Kukreja

Master's Projects

In-depth understanding of the complexity of daily human activities is crucial for building responsive health monitoring and assistive technologies. However, limited research has focused on distinguishing activities based on their involvement level, as most existing work classifies only the type of activity performed. In this thesis, we address this gap by proposing a method to classify human activities as either simple or complex using sensor data from the Opportunity dataset. We define complex activities as those involving object interactions or multiple coordinated movements (e.g., drinking from a cup, cleaning a table), and simple activities as static or low-effort postures (e.g., …

Unconditional-To-Conditional Transfer And Optimization For Web-Based Skybox Gan, Crystal Kwong

Master's Projects

Generative adversarial networks (GANs) are known for their ability to generate high quality
images mimicking real life or even particular art styles. Yet for all their capability, casually
training a GAN on an average machine can be infeasible as GANs require an enormous amount
of time and data to train. Even with a trained GAN, model inference demands heavy
computations, making GANs difficult to deploy on applications. To address these limitations,
techniques such as transfer learning and quantization have been leveraged to speed up training of
GANs and lighten computational cost of GAN inference. This project aims to use such …

Only connectivity begets connectivity. Lua is an extensible and high-performing scripting language based on ANSI C. The language is popular in many fields but faces security challenges. Lua has a non-traditional …

Combining Esm Models With Experimentally Derived Structural Stability To Identify Functional Missense Mutations, Rucha Deo

Master's Projects

Missense mutations can impact protein function and structure, yet their effects on protein function are difficult to predict. In this study, I compared two deep learning models, ESM1v and ESM1b, by evaluating their mutation predictions against experimental structural stability data. ESM1v showed a stronger correlation with experimental structural stability scores compared to ESM1b. A sigmoid curve was fitted to explore this relationship further. Over 100,000 mutations were identified where experimental stability differed significantly from model predictions. Many mutations that remained structurally stable experimentally but were predicted as harmful by the ESM models were frequently found at known functional sites. Structural …
