Reliability-Based Performance Evaluation Of Slurry Wall For Leakage Control At Chakaria Landfill, Bangladesh, Shishir Bhandari

Civil Engineering Theses

Landfill leachate threatens groundwater quality in low-lying coastal Bangladesh, where a shallow water table and a discontinuous natural clay barrier heighten contamination risk beneath municipal solid waste sites. At the Chakaria Landfill in Cox's Bazar District, a cement-bentonite slurry wall was proposed as a vertical cutoff to control seepage, but its reliability under the site's high-groundwater condition had not previously been evaluated in probabilistic terms.

This study evaluated the wall's performance using a two-dimensional SEEP/W finite-element seepage model, a validated response surface (RSM) equation relating seepage rate to wall permeability, thickness, depth, and a Hasofer-Lind first-order reliability (FORM) analysis built …

Investigating Ui Based And Ai Based Interactions In Vr Environments For Human Anatomy Education, Siddharth Sondhi

Master's Projects

Traditional approaches to learning and simulation often struggle to convey the complexity of three dimensional structures. In anatomy education, methods such as textbooks, lectures, and cadaver based learning are used, but can make it difficult to understand the complex structure of organs within the human body. Virtual Reality (VR) offers a promising alternative by providing immersive and interactive 3D environments that allow users to explore and manipulate anatomical structures more intuitively. These environments can be further enhanced by integrating large language models (LLMs) as intelligent agents capable of guiding users through natural language interaction. This project presents a Unity-based VR …

Improving Pid Control With Bayesian Optimization For Adversarially Robust Federated Learning, Adrian Pena, Sergei Chuprov, Raman Zatsarenko, Leon Reznik

Computer Science Faculty Publications

Federated Learning (FL) often suffers from unstable convergence and reduced robustness under non-IID data and malicious attacks. In this paper, we present FedPIDAvg_tuned, a control-theoretic aggregation framework for improving stability and adversarial robustness in FL. In particular, our approach combines a server-side Proportional–Integral–Derivative (PID) controller with Bayesian optimization to tune controller gains for different data and attack conditions. The PID controller regulates global model updates through feedback on loss dynamics, providing adaptive scaling that improves stability and convergence. The tuned gains are applied within a trust-weighted trimmed-mean mechanism to remove adversarial or outlier updates. Using the Flower framework, we evaluate …

Utilizing A Suction Catheter As A Makeshift Tracheostomy Tube In A Premature Infant: A Case Report., Ashwini V Bandi, Shaina W Gong, Gabriela G Cruz, Alicia S Lore, Kunal Shetty, Sancak Yuksel

Faculty, Staff and Student Publications

One of the most challenging aspects regarding pediatric tracheostomy tube placement is the size selection, particularly in preterm infants. We present the first reported case of a makeshift tracheostomy tube using a 6-French suction catheter in a 31-week-old premature infant in an emergent situation. This approach holds promise as a potentially life-saving intervention for extremely small preterm infants. Furthermore, this case emphasizes the size discrepancy between the premature neonatal airway and the smallest tracheostomy tubes available. Further research is warranted to allow for more diverse clinical solutions that can accommodate similar cases in acute settings.

Ventilation-Perfusion Scan: A Functional Imaging Approach To Regional Lung Disease In Primary Ciliary Dyskinesia, Gabriel Román-Ríos, Gabriel Rosario-Ortiz, Marcos J Ramos-Benitez, Ricardo A Mosquera, Wilfredo De Jesús-Rojas

Faculty, Staff and Student Publications

Introduction: As a rare genetic disorder defined by defective ciliary motility, Primary Ciliary Dyskinesia (PCD) leads to chronic respiratory complications. A founder variant in the RSPH4A [c.921+3_921+6delAAGT] gene, common in Puerto Rico, impairs ciliary function and contributes to progressive lung disease. Today, the clinical value of ventilation/perfusion (V/Q) scans in PCD has not been thoroughly investigated as well as pulmonary function tests (PFTs) and chest imaging. To explore the role and clinical utility of V/Q scans in PCD.

Methods: Retrospective evaluation of pulmonary function tests, chest imaging, and Tc-99m DTPA ventilation and Tc-99m MAA perfusion scans in ten patients with …

Transcripts from these sessions underwent thematic analysis to identify key patterns related to …

"Art, Esthetics, Ideal": An Ethics For Literary Translators In The Age Of Translating Machines, Gabriel González Núñez

Writing and Language Studies Faculty Publications

The advent of effective machine translation has raised several issues for translators, including the question of how a human translator ought to translate in this age of translating machines. In this context of new ethical questions, the present essay argues that an answer may be found in Pedro Figari’s (1912) philosophical essay on esthetics. Following Figari, the current essay argues that literary translation is art, that as such it can produce an esthetic emotion on readers and that the purpose of such art and esthetics is an ideal in the form of the continuous betterment of the human condition.

Creating A University-Based Accessible Makerspace For Use By Local Community Members Through Participatory Design Workshops, Erin Higgins, John J. Magee Iv, Foad Hamidi

Computer Science

While Do-It-Yourself Assistive Technology (DIY-AT) has been shown to provide needed AT for individuals who might not otherwise have access, the makerspaces utilized to create these technologies have proven to be inaccessible. A promising direction for creating accessible makerspaces is to utilize participatory methods to develop new spaces for use by a diverse community of individuals. We explored these possibilities through participatory design workshops focused on building a new accessible community makerspace situated within a university campus setting. Through these workshops, we found that there are unique physical, technical, and human supports needed to create an accessible space for the …

Climate Change And Species Interactions Jointly Shape Migration Timing And Growth At A Critical Ontogenetic Transition In Juvenile Sockeye Salmon, Margaret E. Veatch

Honors Theses

Climate change is shifting the timing of biological events globally, but the mechanisms linking environmental variation to phenological changes are poorly understood in many systems, particularly those where individuals undergo ontogenetic habitat shifts. Here, I examined the join influence of climate-driven environmental variability and species interactions migration timing and body size at migration in juvenile sockeye salmon (Oncorhynchus nerka) in Lake Aleknagik, Alaska, using a multi-decadal dataset (1967–2024). Migration timing varied widely among years and was best explained by a combination of ice-out phenology, epilimnetic temperature, and fish densities in littoral habitats. Juvenile sockeye salmon migrated earlier in …

From Sorochyntsi To St. Petersburg: National Identity In The Works Of Nikolai Gogol, Gary Jay Kogoy Jr.

Honors Theses

Nikolai Gogol's extant works depict a man torn between his birthplace of Ukraine and the nineteenth-century milieu of Imperial Russia. Notably, he did not reveal his name for some time after publishing his first story collection Evenings on a Farm Near Dikanka; as a result, readers attributed the tales of Ukrainian life within not to Gogol, but to the charming "Ukrainian jester" persona of Rudy Panko. Even after revealing his identity and garnering respect in the St. Petersburg literary scene, his contemporaries often viewed him as sly and suspicious because of his ancestry. Perhaps due to external doubts regarding …

This thesis examines the contemporary work of community-based Maine midwives through the theoretical framework of choreography. In the context of this work, choreography can be understood as the well-thought-out, purposeful undertaking of a process during which negotiation, coordination, and improvisation are required to adapt to constantly changing circumstances. Using choreography, this thesis attempts to understand how Maine midwives navigate global market processes and practice under authoritative forms of biomedicine, ultimately linking them to other midwives across various global sites. Situated within Maine’s maternal health landscape that is characterized by the ongoing closure of labor and delivery units and rural hospitals, …

Ultra-Processed Or Ultra-Addictive? A Demand-Based Redefinition Of Ultra-Processed Foods, Braden Jondro

Honors Theses

Ultra-processed foods now comprise the majority of the U.S. food supply and have been directly associated with 32 chronic diseases including obesity, cardiovascular disease, cancer, and diabetes. Current classification systems such as NOVA provide a useful framework for identifying food processing, but rely on broad and subjective categorizations that may not capture the mechanisms most closely associated with promoting persistent overconsumption. In particular, existing classification systems remain limited in their ability to evaluate addiction-like behaviors associated with highly processed foods, including persistent purchasing patterns, reinforcement effects, and substitution responses. This paper introduces the Ultra-Processed Food Intensity (UPFI) index, an objective, …

Between Commodity And Culture: Tea Advertising As A Site Of Imperial Ideology And Anti-Colonial Resistance In India, Sydney Pascal

Honors Theses

Between the late nineteenth century and Indian independence in 1947, tea advertising became a key site through which imperial authority and Indian nationalism were negotiated. Drawing on advertisements, trade journals, and visual marketing campaigns produced from the 1880s through the 1950s, this honors thesis argues that tea advertising was a cultural and political mechanism through which the British Empire attempted to normalize imperial consumption and legitimize colonial authority. British campaigns framed tea as modern and routine while obscuring the exploitative labor systems and landscape transformations that sustained plantation production in Assam. As nationalist movements expanded in the early twentieth century, …

Blood And Belonging: Remembering Massacres Of The American West In The Twentieth Century, Mountain Meadows And Sand Creek, Kenzie Burns

Honors Theses

The late nineteenth and early twentieth centuries marked a turning point in mainstream America’s sense of national identity. A wave of nostalgia for the American Frontier enshrined the region’s idealized nineteenth-century past as myth. A key part of the story is romanticized violence—often depicted through cultural imagery of cowboys, gunfights, and battles with American Indians. This project seeks to understand more about how violence is represented in the cultural memory of the American Western past. Within the past twenty years, scholars of the American West have begun to incorporate the study of memory into their scholarship, frequently with how cultural …

Brewing Resilience: Cooperatives, Micro-Mills, And The Quest For Survival In Costa Rica's Changing Coffee Landscape, Leila N. Iredell

Honors Theses

This thesis examines how different organizational models in Costa Rica's coffee sector shape producers’ ability to capture value, build resilience, and sustain rural livelihoods in a rapidly changing global market. In comparing traditional cooperatives and new micro-mills, I examine specifically how control over the value chain, access to markets, and social infrastructure differ across models and what these differences mean for the farmers who depend on them. This project analyzes how the collapse of international price agreements and decades of market volatility drove producers toward new strategies, from independent processing and direct trade to coffee tourism. Costa Rica stands as …
