Edge Co-Occurrence Regularization For Node Classification, Kadir Altunel

Theses

We propose a simple yet effective regularization technique for node classification on graphs that leverages edge-based label co-occurrence patterns. We first train an MLP on node features to produce class probability distributions, then compute a fixed penalty matrix from edge-based co-occurrence statistics of these predictions. This penalty matrix, which captures unlikely class combinations on connected nodes, is then used to regularize GNN training without further updates. We evaluate this approach across multiple homophilic datasets (Cora, CiteSeer, PubMed, ogbn-arxiv) and heterophilic benchmarks (Chameleon, Squirrel, Actor, Roman-Empire) using three GNN architectures: GCN, GraphSAGE, and H2GCN. Results show consistent improvements on homophilic graphs, …

Deep Learning Approaches For Ctenophore Identification And Tracking, Anagha Bharadwaj

Theses

Ctenophores are translucent marine organisms with nearly invisible tentacles and pose significant challenges due to their transparent morphology and ambiguous structural features. This research addresses the classification and tracking of these organisms and evaluates the performance of current computer vision models under sparse-data environments.

Evaluation Of Medical Instrument Reliability For The Heath And Maddox Components Of The Accommodative-Vergence System, Jacob Chabuel

Theses

Binocular vision relies on the coordination of near response triad composed in part by the vergence and accommodative systems. Binocular dysfunctions linked to these systems impact the quality of life of those affected by complicating day-to-day tasks and leading to further health concerns. Clinical evaluations that diagnose dysfunctions and tailor therapies rely on subjective methods, creating a need for a reliable, quantitative, measurement tool. This is achieved using a haploscope, a tool that quantitatively measures and observes binocular vision to identify deficiencies within the eye. Modernization of a haploscope system, measurement of the Heath and Maddox components of the visual …

Polarimetric Terahertz Imaging For The Measurement Of Birefringence In Plastic, Rachel Cohen

Theses

Birefringence offers a promising way to observe stress concentration in materials such as glass and plastic, and thereby to identify weaknesses. Polarimetric imaging can be used to measure the birefringence of material, so long as the material is transparent to the light being used for the imaging. In this research, 2D Terahertz imaging was investigated as a means of measuring the birefringence of plastics that are opaque to visible light but transparent to THz radiation, for the eventual purpose of analyzing the residual stress present. In order to do so, two separate terahertz cameras were characterized for potential use in …

Retinomorphic Mid-Wave Infrared In-Sensor Processing Engine: Device-To-Architecture Co-Design, Hemalatha Nagaraju

Theses

Conventional frame-based CMOS image sensors acquire full-frame pixel data at discrete time intervals, resulting in substantial spatial redundancy and loss of temporal information between frames. The repeated conversion and transfer of redundant pixel data increases bandwidth and power consumption in machine vision systems. Retinomorphic sensing architectures address these limitations by enabling programmable, analog-domain processing directly at the sensor interface. A compact behavioral model of the PbSe device is developed in HSPICE based on calibrated TCAD simulation data to capture gate-controlled photocurrent modulation under varying illumination and gate bias conditions. Error analysis is performed to quantify the deviation between TCAD-generated photocurrent …

The Impact Of Employment On Sense Of Belonging And Metacognitive Awareness: A Mixed-Methods Study Of Undergraduate Students’ Mathematical Performance, Erin Ryan

Theses

This study investigated how employment intensity affects two critical factors for academic success: a student’s sense of belonging and their metacognitive awareness (the ability to monitor and manage their own learning). Using a mixed-methods approach at the Rochester Institute of Technology, we analyzed survey data through multi-level modeling and conducted qualitative interviews to capture the personal experiences of employed students. Results reveal that students working off-campus for more than eleven hours a week showed significantly lower sense of belonging and metacognitive awareness scores than unemployed students. However, on-campus employment did not show the same effect. Both quantitative and qualitative results …

Uncovering Cytoskeletal Length Control From Growth Trajectories Using Sparse Dynamical Modeling, Carson Hearn

Theses

Understanding the governing equations of biological filament dynamics is essential for predicting cellular behavior, yet these equations are often difficult or impossible to derive directly from first principles. This thesis investigates the use of Sparse Identification of Nonlinear Dynamics (SINDy) as a unified, data-driven framework for discovering, validating, and refining governing equations from both simulated and experimental data. Focusing on biological filament processes, including growth, disassembly, and severing, this work is designed not only to apply SINDy, but to systematically demonstrate that it is a reliable and generalizable tool for modeling complex biophysical systems. To establish this, SINDy is first …

Gender Symbolism, Emmanuel Joseph Okechukwu

Theses

This thesis, Gender Symbolism, explores how contemporary ceramic practice can be used to challenge colonial ideas of gender and reclaim African perspectives on identity. Drawing from personal experience growing up in Nigeria as someone who did not conform to rigid expectations of masculinity, this work examines how gender has been historically constructed, policed, and misunderstood within both African and Western contexts. Through research into pre-colonial Nigerian societies, this thesis argues that gender was once understood as fluid, situational, and socially defined, rather than fixed within binary categories. The imposition of colonial rule, Christianity, and Western legal systems introduced rigid gender …

Tom: Toward A Design Language For Object Personality, Mike Minerva

Theses

Design has been chasing seamless efficiency for decades, creating smoother interactions, more compliant objects, and experiences that disappear entirely. When an object is frictionless, it does not lack personality. It has a personality. One that is obedient, meaningless, and remarkably boring. An object that pushes back has boundaries, and that resistance comes from a position of caring. Objects have always been able to refuse. What is new is that the refusal can now come from inside the object, from memory, adaptive thinking and a disposition toward the person using it. Expressed consistently over time, that agency is perceived as personality. …

Bio-Based Materials In Adaptive Reuse: Assessing Durability, Disassembly, And Reuse Potential, Gloria Barry

Theses

This study evaluates the performance of bio-based and conventional wall assemblies in relation to their ability to be disassembled and reused after exposure to environmental stress. While durability is often prioritized in construction, this research examines whether materials that resist change are also those most suitable for reuse. Four wall assembly types, two conventional (CMU with EPS insulation) and two bio-based (compressed earth blocks with hemp insulation), were constructed, each with two specimens to establish control and test conditions, using different connection strategies, including 1/2-inch mortared systems and a combination of thin mortar-slip joints with mechanical fasteners. Assemblies were subjected …

Topological Perspective On Temporal Climate Networks, Daniel Oleynikov

Theses

Networks are highly effective tools for analyzing the dynamics of Earth’s climate system. In this approach, nodes represent geographical locations and edges represent correlations or causal relationships with respect to climate fields, such as air and sea surface temperatures. We extend this technique by integrating it with topological data analysis (TDA), which shifts the focus from pairwise relationships—typical of conventional network methods—to higher-order interactions among geographic locations. Through techniques such as persistent homology and simplicial distributions, we investigate how the global climate dynamics—summarized by this representation—have evolved over the last 75 years. Additionally, we evaluate changes in oceanic connectivity with …

Mathematical Models Of The Kinetic Release Of Therapeutics From Contact Lenses And Their Effects On The Ocular Immune System Response To Allergic Conjunctivitis, Narshini D. Gunputh

Theses

Seasonal allergic conjunctivitis (SAC) is one of the most common ocular disorders caused by exposure to airborne allergens such as pollen. It is typically treated with eye drops, but only about 5% of the drug in an eye drop reaches the target tissue. Drug-eluting soft contact lenses have been proposed as an alternative delivery method, but one limitation of a contact lens is the burst-release. In this thesis, we develop multiple mathematical models to support the design and evaluation of drug-eluting contact-lenses for the treatment of SAC. In the first part of the thesis, we build a diffusion-based model to …

Mathematical Modeling Of Ocular Surface Deformation Due To Contact Lenswear That Accounts For Intraocular Pressure, Riley K. Supple

Theses

Myopia is one of the most common ocular disorders, and is expected to affect approximately five billion people worldwide by 2050. One treatment currently available for myopia is soft contact lenses. In general, about one in ten Americans wear contact lenses, however one in three will stop wearing them due to discomfort. The goal of this dissertation is to develop a mathematical model that predicts the mechanical interactions between the contact lens and the ocular surface. Assuming the ocular tissue is a linear elastic material, we first develop a mathematical model to predict ocular deformation that is anatomically accurate in …

Material Selection In The Mountain West: A Multi-Criteria Decision Analysis (Mcda) Based Approach For Architects, Melissa Bach

Theses

With modern advancements in technology and the expansion of a globally interconnected network, architects have access to a large range of building materials. Increasing public concern for the environment has prompted architects to prioritize materials that are more sustainable, but varying definitions of sustainability, coupled with unclear guidelines for material selection, repeatedly lead to uncertainty and decision-making challenges within the profession. To address this, a comprehensive methodology such as Multi-Criteria Decision Analysis (MCDA) is needed for the material selection processes. Furthermore, a gap in the literature demonstrates that the application of MCDA for material selection in the Mountain West region …

Quantifying Exterior Ecological Performance In Biomimicry, Bioclimatic, And Biophilic Architecture: A Comparative Framework Across Climatic Zones, Ruqayyah Siamwala

Theses

Historically, sustainability research in architecture has focused on interior comfort and operational energy efficiency, leaving the ecological performance of the immediate building façade relatively unexplored. By creating a comparison framework to assess the performance of biomimetic, bioclimatic, and biophilic architecture under external ecological conditions across four climatic zones—hot-humid, cold-humid, hot-dry, and cold-dry—this thesis closes that gap. Using quantitative data such as NDVI, land surface temperature, PM2.5, NO2, infiltration rates, and species count in addition to qualitative analysis of these three architectural strategies at the building-site interface, twelve case studies are evaluated against four ecological indicator groups: air quality, soil quality, …

Using a qualitative approach, I conducted a focus group to hear directly from seniors about their experiences with technology, what challenges they face, how they feel about using it, and what support they need. Guided by Critical Race Theory and the concept of digital inequality, my analysis highlights the gap between access …

Reclaiming Suppressed Symbols: Yoruba Iconography And Nuyorican Identity In The Art Of Nitza Tufiño, Ariana Williams

Theses

This thesis examines the work of Afro-Puerto Rican artist Nitza Tufiño through Yoruba iconography, diasporic memory, and gendered Nuyorican identity. Grounded within the cultural and political context of the Nuyorican Movement of the 1960s and 1970s and, this study argues that Tufiño’s visual practice reframes suppressed African spiritual symbols through a woman-centered perspective, positioning Black femininity and spiritual labor as sites of resistance to colonial erasure and racial marginalization. Drawing upon Yoruba-derived cosmologies, Santería, and processes of visual syncretism, Tufiño integrates African, Indigenous Taíno, and Caribbean traditions to articulate a gendered visual language rooted in care, ritual, and collective memory. …

Urban Illumination And Circadian Disruption: Examining Artificial Light At Night, Caitlin Mcmasters

Theses

Artificial light at night is increasingly prevalent in dense urban environments, yet it remains unclear how often typical city lighting conditions likely exceed recommended nighttime limits for residential circadian health. This thesis evaluates nighttime light exposure in two contrasting urban districts, Back Bay in Boston and Times Square in New York City, using satellite derived nighttime radiance, GIS based urban morphology, and documented lighting infrastructure characteristics. Rather than relying on calibrated photometric simulations, the study employs a qualitative, evidence based comparative approach to assess relative façade exposure and interpret conditions against established benchmarks, including the WELL Building Standard and ILP …

Traumatic Stress Recruits An Excitatory Orbitofrontal-Amygdala Pathway To Drive Maladaptive Aggression, Mikaela Aholt

Theses

Traumatic stress is a reliable predictor of heightened aggression, yet the mechanisms linking stress exposure to aggression remain poorly understood. The Nordman lab previously found that traumatic stress activates the posterior ventral segment of the medial amygdala (MeApv) to drive persistent increases in aggressive behavior. However, why traumatic stress would engage an aggression-promoting pathway is unclear. To address this, the inputs to the MeApv were mapped and a population of excitatory, but not inhibitory, neurons in layer 5 of the medial orbitofrontal cortex (mOFC) were identified. The OFC is classically viewed as an inhibitory brake on amygdala-driven impulses, yet emerging …

Study Of Global Panel Of Soybean Accessions For Nitrogen Use Efficiency Using Association Mapping, Rita Bhandari

Theses

Soybean (Glycine max [L.] Merr.) is a leguminous crop valued for its high protein, oil content, and other essential nutrients. Global production has significantly increased, with Brazil, the United States, and Argentina being the leading producers. In the U.S., Illinois, Iowa, and Minnesota rank as the top soybean-producing states. Nitrogen (N) is a predominant nutrient required for optimal soybean growth and productivity, particularly in high-yielding varieties. While biological nitrogen fixation and soil mineral N supply part of the plant’s N requirement, synthetic fertilizers are commonly used to meet the remaining demand. However, only 30–50% of applied N is taken up …

Evaluation Of Otolith Microchemistry For Identifying Walleye Stocked As Fry Or Fingerlings, Joshua Fluur

Theses

Walleye (Sander vitreus) is a popular sport fish whose populations are often supported by maintenance or supplemental stocking, with most fish stocked as fry, fingerlings, or advanced fingerlings. Evaluation of stocking efficacy is important to inform decisions regarding fish stocking rates and sizes and allocating hatchery fish to locations where maintenance or supplemental stocking is most needed. Several types of artificial tags or marks have been proven useful in the identification of stocked fish, but they often have various drawbacks. Natural chemical markers in otoliths offer several advantages compared to conventional tags or marks and can be used to identify …

Indiana Bat Population Dynamics In The Midst Of Climate Change And White-Nose Syndrome, Lexie Ann Schwartz

Theses

Climate change and emerging diseases are altering species distributions and ecosystem dynamics worldwide. For temperate insectivorous bats in North America, food availability and winter climate influence hibernation energetics and survival. As climate warming alters insect phenology, these changes are likely to have an impact on hibernating bats. Many cavernicolous bats in North America are also threatened by white-nose syndrome (WNS), a newly emerged fungal disease devastating bat populations. This study examined the distribution of hibernating Indiana bats (Myotis sodalis) over time throughout their range. I used long-term weather data to simulate seasonal insect availability, the spring and autumn transitory periods, …

3d Infographic Animation Series Unleashing The Mechanism Of Disease (Mod) Of Ventricular Tachycardias In Cellular And Molecular Levels: Afterdepolarization Subtypes And Triggered Activity, Yan Ning ‘Harmony’ Wong

Theses

Ventricular arrhythmias (VAs) account for 75-80% of sudden cardiac deaths, causing 184,000 to 450,000 deaths annually in the U.S. VAs commonly occur in individuals with structural heart diseases, but idiopathic ventricular tachycardias (VTs) caused by delayed afterdepolarizations (DADs), early afterdepolarizations (EADs) and triggered activity, can also arise due to calcium ion discrepancies without apparent structural abnormalities. Despite advances in understanding abnormal impulse conduction, there is a paucity of visual aids that explain impulse formation anomalies of VTs. There are no 3D animations that link ECG interpretation to molecular dynamics in the cardiac EC coupling process. Moreover, ECG interpretation skills are …

What If You Were My Fucked Up Dad And I Was Your Fucked Up Boy And We Cried Together, Ferris Ramirez

Theses

When I was six, maybe seven, my father said I would be disowned if I ended up a faggot. Twenty years have passed since I learned to perform as someone else around my father. As I come to terms with our irreparable estrangement, I present a question to the father I fail to connect with and to an imagined man: What if you were my fucked up dad and I was your fucked up boy and we cried together? This line of inquiry is the very title of my multimedia series, framing concepts of projection, queer desire, fatherhood, role-playing, and …

Microbial Composition In The Context Of Rising Temperatures And Chytrid Infection, Emma G. Thompson

Theses

Chytrid fungi, Bd (Batrachochytrium dendrobatidis) and Bsal (Batrachochytrium salamandivorans), are one of the largest threats to amphibian populations worldwide. Research has shown that the amphibian's skin microbiome can inhibit Bd/Bsal infection, but that microbial composition can vary drastically with host and environmental factors. In addition, habitat-wide mitigation methods that capitalize on the thermal mismatch between Bd/Bsal and their hosts (e.g., warming the host or environment) have been proposed to combat infection. These methods have proven successful so far, but do not consider the indirect effects that warming has on the microbiome. Synthetic microbial communities of ten core members to simulate …
