Fault Tolerance Of Accelerated Asynchronous Fixed-Point Iterations On Flexible Computing Infrastructure, Evan Coleman, Masha Sosonkina

Electrical & Computer Engineering Faculty Publications

Asynchronous iterative methods tolerate straggling processors by allowing workers to proceed with stale data, but at a cost: the iterates become inconsistent, potentially degrading convergence. We investigate whether convergence accelerators such as Anderson acceleration compensate for this degradation. We experimentally study three fixed-point iterations: the Jacobi method for sparse linear systems, value iteration for the Bellman equation, and the Hartree–Fock self-consistent field (SCF) iteration. The experiments are conducted using a high-performance execution framework, Ray, which abstracts the complexity of distributed systems and enables code parallelization and fault injection with minimal changes.

We establish two main results. First, straggler tolerance is …

Electrical & Computer Engineering Faculty Publications

Digitally captured handwriting preserves pen trajectories and dynamic signals, but it also records hardware- and input-dependent properties that can confound forensic interpretation. This study revises a support vector machine (SVM) screening framework using 16,500 samples from 30 writers, 11 writing-content categories, and five acquisition conditions spanning three tablets and stylus or finger input. Twenty-four raw and derived time-series variables were summarized by maximum, minimum, mean, median, and standard deviation, yielding 120 features; the mode statistic was removed. Writing direction and angular velocity were recalculated with atan2-based vector formulas. Unavailable device/API channels were encoded as zero, and Z-score parameters were estimated …

Multivariate Quantile Autoregression-Mixed Data Sampling (Mvqar-Midas) Modeling Of Cost Of Living And Supply Chain Dynamics In Canada., Patrick Gbolonyo

Theses and Dissertations (Comprehensive)

In recent years, the rising cost of living as a result of persistent inflationary pressures, disruptions in the global supply chains, and changes in the macroeconomic landscape has become a critical topic of discussion. To address this, we move beyond a mean-based framework and employ a quantile regression approach. This allows the persistence of each series and the transmis- sion of shocks between the Consumer Price Index (CPI) (the total CPI which is a percentage change over the past 12 months), the Interest Rate (IR)(the target for the overnight rate), the New Housing Price Index (NHPI), and high-frequency supply chain …

VMASC Publications

Background/Objectives: Accurate assessment of neuromuscular reflexes, such as the Hoffmann reflex (H-reflex), plays a critical role in sports science, rehabilitation, and clinical neurology. Conventional interpretation of H-reflex electromyography (EMG) waveforms is subject to inter-rater variability and interpretive bias, limiting reliability and standardization. This study aims to develop an automated, interpretable, and robust agentic AI–driven framework for H-reflex waveform analysis. Methods: We propose a fine-tuned Vision–Language Model (VLM) consortium combined with a reasoning Large Language Model (LLM)–enabled decision support system for automated H-reflex interpretation. Multiple VLMs were fine-tuned on curated datasets of H-reflex EMG waveform images annotated with expert clinical observations, …

Student performance was measured as the percentage of independently completed responses across instructional sessions. Student T demonstrated meaningful improvement in independent AAC requesting and reached 75% independence in the final session. Student B demonstrated emerging improvement in timer-setting performance and reached 60% independence …

Examining Marginalized Sexual Identity Development Through Perry’S Scheme Of Cognitive Development, Miranda Bejda

University of Kentucky Doctoral Dissertations

Existing models of LGBTQ+ sexual identity development are critiqued for their linearity and lack of inclusion for diverse experiences and sexual identities. There is a call for a more robust understanding of the cognitive aspect of sexual identity development. The purpose of this dissertation is to further the understanding of how people think about their sexual identity through the developmental process using Perry’s scheme of cognitive development as a framework. Through semi-structured interviews, I analyze the LGBTQ+ sexual identity development process (Stage 1), how Perry’s scheme applies to LGBTQ+ sexual identity development (Stage 2), and propose a Perry-informed model of …

Cognitive Validity In Listen-To-Write Summary Tasks: A Mixed-Methods Analysis Of Notetaking Data, Rebecca Yeager, Gomee Park, Junhee Park

Bilingual and Literacy Studies Faculty Publications

This study examines the cognitive validity of a listen-to-summarize task on a university placement test. Cognitive validity is underinvestigated in listening assessment, especially for higher-order listening processes (Holzknecht et al., 2017; Rukthong, 2021). However, student notes from listening tests can record evidence of these processes (Yeager et al., 2024; Cushing, 1991). This study employed an exploratory sequential mixed-methods design to investigate the higher-order listening processes elicited by an integrated listen-to-summarize task. First, notes from two administrations of the same test form – one with notetaking scaffolding (n = 25) and one without (n = 25) – were analyzed qualitatively. Second, …

Validating Uas-Based Ndvi Data With Satellite Landsat Imagery For Bald Eagle Habitat Prediction In The Del Rio Springs Ecosystem, Noah Morales, Colton Weeks, Hank Vincent, Ronny Schroeder

Student Works

Vegetation health is commonly assessed using the Normalized Difference Vegetation Index (NDVI), which can be derived from multispectral sensors operating at different spatial resolutions. Validating NDVI products across sensor platforms is essential to determine their reliability for environmental monitoring and habitat assessment. This research compares NDVI derived from moderate-resolution satellite imagery and high-resolution unmanned aircraft system (UAS) imagery collected over the same study area. Landsat imagery, provided through the joint USGS–NASA mission, was used to represent satellite-based vegetation patterns, while high-resolution multispectral data were acquired using a MicaSense sensor mounted on a UAS to capture fine-scale vegetation detail.

A Portable Potentiostat Integrated With A Pt/Zno/Lig Electrode For Non-Enzymatic Glucose Detection, Reagan Aviha, Gymama Slaughter

Center for Bioelectronics Publications

Continuous glucose monitoring is critical for effective diabetes management; however, conventional benchtop potentiostats are bulky, costly, and unsuitable for decentralized point-of-care (PoC) applications. To address these limitations, this work presents a miniaturized, low-cost electrochemical sensing platform integrating a non-enzymatic glucose sensor with a portable potentiostat. The sensing electrode is based on laser-induced graphene modified with zinc oxide and platinum nanostructures via electrodeposition to enable sensitive glucose detection under physiological conditions. A custom-designed portable potentiostat was developed to control electrode potentials and perform electrochemical measurements, and its performance was experimentally validated against a commercial Metrohm system. Glucose detection was evaluated using …

Étude Multidisciplinaire Du Confort Des Bouchons D'Oreilles : Vers Une Protection Auditive Efficace En Milieu De Travail, Olivier Doutres, Franck Sgard, Alessia Negrini, Alain Berry, Chantal Gauvin

Rapports de recherche scientifique

L'utilisation de protecteurs auditifs individuels (PICB), tels que les casques ou les bouchons d’oreilles souvent recommandés comme mesure temporaire, reste souvent le seul moyen d'assurer la protection des travailleuses et travailleurs exposés quotidiennement à des niveaux de bruit dangereux. Actuellement, le choix d'un PICB est principalement basé sur des considérations liées à l’atténuation acoustique qu’il offre (et mesurée en laboratoire par des organisations certifiées), et/ou à des caractéristiques de l'environnement de travail, telles que la chaleur, l'hygiène et la compatibilité avec d'autres équipements de protection individuelle (EPI). Le port de PICB est connu pour générer de nombreux inconforts qui peuvent …

Green As Cure: The City Beautiful Movement And The Spatial Politics Of Health, 1870-1950, Avi Patel

Library Map Prize

At the turn of the twentieth century, Progressive Era reformers understood the American city not merely as disordered but as pathological—an environment that bred disease and eroded civic life. This thesis argues that the City Beautiful Movement (CBM), embodied in Washington's 1902 McMillan Plan, advanced a spatial logic it terms "green as cure:" the conviction that disciplined landscape design could function as a form of environmental medicine, restoring health to the urban body. Drawing on maps, planning documents, and congressional reports, the thesis shows how plans defined disorder, prescribed intervention, and embedded assumptions about race and belonging into the built …

Searches And Seizures Of The Unhoused, Shawn E. Fields

Faculty Scholarship

The United States recorded its largest ever unhoused population in 2024. Acute affordable housing shortages and climate-fueled natural disasters have exacerbated a decades-long unaddressed humanitarian crisis, straining resources in cities and rural areas alike. In response, state and local governments have pivoted to a more punitive approach to houselessness. Draconian "anti-camping" ordinances subject houseless people to fines or arrests while police destroy their property in encampment "sweeps," disconnecting the unhoused from critical social structures. Quality-of-life laws criminalize basic biological functions in public. New York, California, and other states have expanded the reach of involuntary civil commitment procedures, forcibly hospitalizing and …

Build, Baby, Build: Federal Takings For Affordable Homes, Desiree C. Hensley

Missouri Law Review

The private housing market in the U.S. fails to produce sufficient affordable housing for the people who need it. Even middle-income Americans are stretched to buy or rent. If local and state governments cannot respond effectively, may the federal government simply use eminent domain to build affordable homes to correct the nation’s housing market, including the high cost of land? Conventional wisdom is that the Constitution prohibits such federal action. This understanding arises from a brief period during which the federal government built fifty housing projects—approximately 21,000 housing units—in thirty-five cities across the United States during the Great Depression. The …

Unreasonable Accommodations: Staple V. School Board Of Broward County And The Case For The Interactive Process In Title Vii Accommodations, M. Thomas Yang

Missouri Law Review

When Congress enacted the Americans with Disabilities Act (ADA) in 1990, it envisioned a unique dispute resolution mechanism within the statute—the interactive process. Under this process, when an employee requests an accommodation from an employer, the two must “work together to assess whether an employee’s disability can be reasonably accommodated.” Although the term “interactive process” does not appear in the ADA’s text, the Equal Employment Opportunity Commission (EEOC) interpreted Congress’s intent and incorporated the interactive process into its regulations to guide disability accommodations. Strangely though, Title VII, which governs religious accommodations, does not include the interactive process in its text …

Integrative Masters Project: Hold That Thought: An Original Picture Book, Jordana Blumberg

Graduate Student Independent Studies

Rooted in personal experience, this picture book follows a group of young children who each listen in their own unique way. The author drew from her own childhood memories of struggling to meet classroom expectations — particularly the challenge of holding back when she had something to say — to craft a story that validates the experiences of children who don't always fit the traditional mold of a "good listener."
