Gamified Gait Rehabilitation Via Real-Time Biofeedback And Adaptive Hip-Exoskeleton Control, Mariya Huzaifa Tohfafarosh

Theses

Gait impairments arise from systemic diseases, age-related degeneration, musculoskeletal dysfunctions, or neurological conditions. While traditional rehabilitation can be effective, they often face challenges such as high costs, inaccessibility, and low patient engagement. To address these challenges, my work introduces a virtual reality-based rehabilitation (VRBR) system, integrating real-time motion and electromyographic (EMG) muscle activation feedback with a gamified virtual environment for enhanced adaptability and engagement. The system includes a custom-designed hip-exoskeleton that provides adaptive spring-like assistance or resistance, supporting both mobility-impaired users and strength training. Assistance levels can be tuned to match the user's progress. Additionally, a custom pressure insole was …

A Novel Framework For Dynamic Graph Representation Learning With Mamba, Ashish Pandey

Theses

Dynamic graph embedding is a key technique for modeling temporal dependencies in evolving networks. While transformer-based models perform well, their quadratic complexity limits scalability on long graph sequences. This thesis compares transformer approaches with the Mamba architecture-a linear-complexity state-space model—for temporal graph embedding.

Two frameworks are proposed: DG-Mamba and GDG-Mamba. DG-Mamba uses standard GCN-based spatial encoding, while GDG-Mamba incorporates domain-aware edge features using Graph Isomorphism Network with Edge Convolution (GraphGINE). Experiments on UCI, Reality Mining, Slashdot, Bitcoin-OTC, and SBM datasets show that Mamba-based models match or exceed transformer performance, especially on graphs with high temporal variability.

The thesis also applies …

Anita’S Plight: Challenging Low Expectations For A Black Girl In A Montreal High School, Lerona Dana Lewis Dr.

The Qualitative Report

In this paper, I examine how a Black adolescent girl in a Montreal high school contests low teacher expectations that resulted in her being directed to a vocational program (Formation à un métier semi-spécialisé, FMS) in her high school. The FMS program prepares children for entry-level careers, defined in the Quebec curriculum as semi-skilled jobs. I (re)present her account in the form of a narrative found poem that explores how the use of found poetry as a heuristic device improves understanding of the school practices impacting the student’s placement in the FMS program. The found poem offers a critical reading …

Analytical Approaches For Identification Of Essential Genomes Of Plasmodium Knowlesi And Babesia Divergens, Sida Ye

Graduate Doctoral Dissertations

Apicomplexa constitute a large phylum of single-celled, obligate intracellular protozoan parasites. Notably, Plasmodium spp. and Babesia spp. are apicomplexan parasites that infect red blood cells. Plasmodium species are the causative agent of malaria and are transmitted by Anopheles mosquitoes, affecting large human populations, whereas Babesia spp., transmitted through the bite of Ixodes ticks cause babesiosis.

In this dissertation, we investigate the essential genome of these parasites using high-throughput transposon mutagenesis. Identifying the essential genome is key to finding new drug targets and understanding resistance mechanisms, a crucial pursuit given the rising resistance to frontline antimalarial drugs and the challenges …

From Industrial Building To Affordable Senior Housing: An Idea Book Beyond Code, Weiyi Ma

Masters Theses

This thesis envisions a proposal to adaptively re-purpose Rhode Island’s extant industrial building stock into affordable housing tailored to the needs of its older and more vulnerable citizens. Architectural dignity, in terms of older citizens amidst this housing crisis, is the creation of living environments that honor their autonomy, comfort, and identity through design interventions that provide accessible, luminous, breathable, and socially enriching spaces, reaffirming their rightful place within the community. With humanistic care and logical rigor, it establishes a mathematical framework for assessment and execution, anchored in five criteria: light, air, space, accessibility, and livability, and presents itself in …

Wooorrmmhooolleess, Kimberly Duck

Masters Theses

By now we all know that the internet is an integral part of our existence. One could argue that this online existence holds equal importance to our physical one. While the lines blur even further and Mark Zuckerberg can’t wait to cosplay the rich computer guy from Ready Player One, I choose to refrain from the existential dread that seems to be inescapable when thinking of the future nowadays. While we often associate the internet with portals (after all, we once called websites “Internet Portals”—in German at least), Wormholes more accurately capture the experience. Portals promise instant connection. But what …

Tree Story, Jia Hu

Masters Theses

What is Nature?

Nature is a system of intelligence. It means designing for efficiency—often by learning from strategies that have evolved over time. In my research, I use patterns to interpret and decode nature.

To explore nature, I began with the red cedar tree, aiming to simulate and predict its growth patterns—forms shaped by both internal biology and external forces. By analyzing its geometry, I sought to understand how trees embody the dynamic relationship between organism and environment. These patterns reveal the adaptive logic of life.

Patterns are central to understanding nature. While tree geometry may appear chaotic, it follows …

Revealing Watery Geologies: Softening The Mississippi River Bluffs In Saint Paul, Minnesota, Chloe Kahn

Masters Theses

How is a place shaped by the geologies beneath it? In Saint Paul, Minnesota, the geologic ground tells the story of the different forces and processes that shaped it through time, but in the most recent geologic period of the anthropocene, industrialization and urban development have covered up these stories. On the edge of downtown, where the city meets the Mississippi River, an eighty foot concrete wall replaces the natural form of the bluff shaped by glacial and riverine activity. This thesis peels back the anthropogenic materials we encounter every day and explores Saint Paul through deep time– exploring how …

Tubo, Shaobo Liu

Masters Theses

In this light, while the pursuit of convenience has advanced human civilization in remarkable ways, it is essential to recognize that creativity depends on more than just abstract thought. It relies on the inevitable process of translating ideas into physical form, engaging both mind and body in a cycle of experimentation, failure, and discovery. Without opportunities to physically manipulate and construct, our creative faculties risk stagnation, underscoring the importance of preserving and reintroducing hands-on, experiential learning into modern life.

The modular system in my work prioritizes physical interaction and open-ended outcomes, which responds directly to the challenges posed by digital …

Field Journal: The Excluded Middle, Carrie E. Kouts

Masters Theses

What does it look like to engage with organisms and landscapes at the periphery of anthropocentric value structures? How does one break the internalized myth that the “built” environment is excluded from the natural world? When does a hyper-mobile and hyper-commodified society confront the exponential crisis of animal death? Within this series of journal entries, field notes, collection observations, weird prose, and sensory musings, one will find questions on the nature of being human and the complex narratives of care we encounter in a world shared with more-than-humans. Each handwritten vignette and photograph from daily life weaves a non-linear and …

The Limits Of Knowing: Determinism, Uncertainty, And What’S Beyond The Human Gaze, Xilong T. Zhang

Masters Theses

This essay traces a personal philosophical and artistic journey from rigid belief in scientific determinism to an evolving embrace of uncertainty, subjectivity, and computational perception. Raised in an atheist, scientifically grounded household in China, the author initially adopted Newtonian determinism and Laplace’s thought experiment of a fully predictable universe as guiding principles. These beliefs informed early artistic practices rooted in Constructivism, geometry, and rule-based aesthetics. However, a failed attempt to fully optimize life through deterministic control led to physical and mental collapse, prompting deeper exploration into Cartesian dualism, quantum mechanics, and the limits of reason. Through Heisenberg’s Uncertainty Principle and …

Graphic Gestures On The Digital Surface; In Defense Of The Observational, Soyoung Ro

Masters Theses

This thesis offers a subjective and process-based exploration of digital tools, challenging the dominant function-driven mindset that often defines digital design today. Rather than prioritizing speed, efficiency, or usability metrics, this work is a shift in focus toward experience, spatial awareness, and the subtle dynamics of interaction.

Rooted in acts of attention—looking inwards, looking outwards—this approach begins by setting aside assumptions about what tools are for, in order to ask how they shape our behaviors and ways of thinking. In doing so, it proposes a design methodology grounded in presence over productivity, process over execution, and agency over automation.

The …

Textus Complexus, Vishakha Ruhela

Masters Theses

textus complexus investigates how language shapes thought by merging scientific rigour and poetic action to challenge reductive narratives. My inquiry stems from a fascination with complexity as an existential condition—one that resists homogenisation, preserves collective memory, and demands inclusive, multidimensional engagement. Hybridity, as a spectrum from complicated to complex, becomes a methodological tool to uncover latent connections that lead to cross-communication, and articulate transitional spaces through recursive processes. By systematising multiplicity via layering, modularisation, and indexing, my work foregrounds expression through form, where structural clarity emerges from cumulative gestures rather than simplification.

The projects in this thesis trace the roots …

Ziyyarah: Ethical And Intra-Active Space For Conducting Interviews With Muslim American Students, Wesam M. Salem

The Qualitative Report

Conducting research with Muslim American participants, who have non-Western roots and are bound to their cultural, linguistic, and religious practices, the prescribed, Eurocentric, and power-laden interviewing practices appear to be unfit and essentializing. This paper extends the argument to de/colonize research practices to create realities that are inclusive of participants' ways of knowing and culture. It also draws from the call for an intra-active and entangled approach to research that emphasizes how researchers and their subjects mutually co-constitute knowledge through their entanglement in the research process. It is also rooted in postcolonial theory, and the concept of the nomadic subject …

A Teacher, A Supervisor, An Undefined Self, Alexa Muse

The Qualitative Report

This article follows the experiences and reflections of an American high school English teacher while evolving a single tenth grade memoir and grammar unit into a published student-led research project over the span of 3 years. As a partner piece, this article supplements my students’ published project, titled “A Teacher, a Tutor, a Friend,” that explores ChatGPT and student perspectives through a thematic discourse analysis under the framework of Figured Worlds (Holland et al., 1998); as their teacher-turned-supervisor, I found that preparing 10th grade students—now called the Lexington Student Research and Publication Collaborative—to grapple with such complex material was a …

Embodying Altruistic Love: The Role Of Emotions In Teaching Black Students With Disabilities Within An Inclusive Elementary School, Joshua Armentrout

Graduate Doctoral Dissertations

Teacher emotions play a pivotal yet understudied role in shaping the educational experiences of Black students with disabilities (SWDs). This study examines how five special educators in a fully inclusive elementary school understand, experience, and navigate their emotions in relation to Black SWDs. Using a qualitative approach grounded in portraiture, this study explores the intersection of race, disability, and emotion, revealing how teachers internalize, resist, and negotiate dominant ideologies within the broader educational system.

Guided by a three-dimensional space framework from the field of narrative inquiry—temporality, sociality, and spatiality—this study traces how educators’ emotions are shaped by past experiences, social …

Blockchain-Based Ai-Assisted Cyber-Physical Systems For Robust And Reliable Machining Processes, Prithbey Raj Dey, David Lee Enke

Engineering Management and Systems Engineering Faculty Research & Creative Works

This study demonstrates the prospects of Blockchain-based Cyber-Physical Systems (CPS) to establish a scalable framework for designing a secured, automated, and traceable modeling in machining processes. Machining operations like turning, being inherently complex, rely on different types of explanatory parameters such as feed rate, depth of cut, cutting speed, tools, and environmental factors. All of these variables significantly influence key response variables like surface quality, tool wear, cutting forces, and energy consumption. The proposed Blockchain-based framework, designed using the Object-Process Methodology (OPM) systems modeling language, enables the reliable exchange of comparative data streams within a unified data analytics platform. By …

Linear Mixed Model For The Surface Roughness Prediction In Hard Turning Operation, Prithbey Raj Dey, David Lee Enke

Engineering Management and Systems Engineering Faculty Research & Creative Works

Surface machining using hard turning is an intricate operation due to the influence of multiple machining parameters, their non-linear interactions, and the inherent variability introduced by different experimental trials. This study proposes a Linear Mixed Model (LMM) for predicting surface roughness, effectively addressing the challenges in traditional linear models, posed by the influencing factors, non-linearity, and interactions. The LMM incorporates variability from both fixed effects, such as cutting parameters (feed rate, depth of cut, and cutting speed), and random effects arising from tool wear across experimental runs. As a result, it provides a more comprehensive understanding of how these factors …

Latah Formation: History And Case Studies, Kylee M. Woodworth

2025 Symposium

The Latah Formation is a series of discontinuous sedimentary interbeds between the flows of the Columbia River Flood Basalts outcropping across northern Idaho and eastern Washington. Ages ranging between the Middle to Upper Miocene, the sediments represent varied fluvio-lacustrine environments. The deposits are predominantly composed of claystones and shales as alternating, laminated couplets, many containing a variety of fossils. Though the sediments may appear similar across localities, they come from different source rocks, ranging from ashes from Yellowstone hotspot to metamorphic rock from nearby hills. These ancient lacustrine and fluvial environments allowed for great preservation of fossils, often in great …

Structural Analysis Of Catawissa Quadrangle, Columbia County, Pennsylvania, Kylee M. Woodworth

2025 Symposium

Catawissa Mountain within Columbia County, Pennsylvania is a part of a much large system of mountains called the Appalachian Mountains. Though little more than hills today, the Appalachian Mountains are some of the oldest mountains in the Americas, dating back to after the separation of the supercontinent, Pangea. This presentation is about the structure interpretations of the Catawissa 7.5 Minute Quadrangle, located in Columbia County, Pennsylvania, including fold analysis of the SW trending Catawissa Syncline, formed from Appalachian fold-thrust belt. These analyses are to decipher how the mountain formed from the surrounding regional tectonics and the timeframe of when the …

The Power Of Storytelling: Creatively Facilitating Conceptual Change In The Classroom, Mackenzie S. Rose, Marcus Johnson

Journal of Educational Research and Practice

Conceptual knowledge encompasses understanding the interrelationships among multiple pieces of information. Misconceptions of these interrelationships illustrate the need for effective educational strategies to facilitate conceptual change, with the goal of facilitating changes in learner understanding to appropriate, accurate, and complete concepts. Strategies, such as refutation texts, have proven effective in addressing science misconceptions, yet there is a prominent gap in research on conceptual change in nonscience subjects and the use of storytelling to facilitate such change. Storytelling, presented in a range of educational subjects, invites learners to engage in social discourses and problem-solving exercises. Prompted by classroom storytelling practices, creativity, …

The Jacod-Yor Theorem For Sigma Martingales And The Second Fundamental, Moritz Sohns

Journal of Stochastic Analysis

In this paper, we prove the Jacod-Yor Theorem for sigma martingales, a class of processes that generalize local martingales and play a pivotal role in financial mathematics. While the Jacod-Yor Theorem has been extensively studied for L2-martingales, martingales, and local martingales, no prior version exists for sigma martingales. Our result establishes the connection between sigma martingales and their martingale representation properties, addressing a critical gap in the literature. As an application, we prove the Second Fundamental Theorem of Asset Pricing for markets where price processes are modeled as sigma martingales.

TM practices were defined as developing talent-oriented attitudes among managers (ITM), building a culture of high performance in the company (BH-PC) and retaining the best employees in the workplace (RT).

Design/methodology/approach: Information on the assessment of TM practices was obtained from the ‘World Management Survey – Manufacturing’ (WMS) database. The studies used the Kruskal-Wallis test (KWt) and the Multiple …

Effective Strategies For Developing And Implementing Metrics For Successful Social Marketing Campaign Performance, Annette M. Wolf

Walden Dissertations and Doctoral Studies

Ineffective use of marketing metrics by social marketers poses a risk of inconsistent and subjective interpretations of campaign success. Social marketing managers and stakeholders are concerned because unreliable metrics hinder their ability to evaluate performance, justify funding, and replicate effective strategies. The purpose of this qualitative pragmatic inquiry, grounded in general systems theory and foundational social marketing literature, was to explore effective strategies that social marketing campaign managers use to implement metrics sufficient to measure successful campaigns. The participants were ten experienced members of the Social Marketing Association of North America, with effective strategies to implement marketing metrics to measure …

Anticommandeering Climate Action: Defending The Necessity Of Subfederal Planet-Saving Legislation, Tyler Hall

San Diego Journal of Climate & Energy Law

Humanity is on the defensive against climate change, and state and local governments are the front line. Regrettably, Americans have waited too long for air cover in the form of federal climate regulations despite an established history of federal environmental action only emerging from the ashes of headline-grabbing catastrophes. Americans cannot wait on federal legislation to tackle the global and unprecedented problem of climate change. It will come far too late.

State and local governments’ historic police power includes protecting environmental health and public welfare, but decades of successful federal regulation have atrophied its use. Delayed by federal success, state …

The Witten Deformation And Proper Cocompact Lie Group Actions, Hao Zhuang

Arts & Sciences Graduate Student Theses and Dissertations

We study the interactions between the Witten deformation of the de Rham exterior differentiation and topological invariants in two scenarios of proper Lie group actions. In the first scenario, we work on a closed oriented manifold admitting an action by a compact connected Lie group. Using a special Morse-Bott function invariant under the group action, we deform the de Rham exterior derivative and get the associated Witten Laplacian. Applying asymptotic analysis, we localize the kernel of the Witten Laplacian around the critical components of the invariant Morse-Bott function. Finally, we build the chain isomorphism between the invariant Thom-Smale complex and …

Influencing Factors Of Angle-Of-Arrival Estimator Based On Deep Learning, Guohao Pang

Dissertations and Theses

Deep learning (DL)-based angle-of-arrival (AoA) estimation offers significant advantages over traditional signal processing methods, especially in complex and high-noise environments. However, situational complexity and differences in hardware can significantly impact the estimator's performance. It is therefore of interest to investigate the relationship between the performance of deep learning models and the variation of physical parameters such as the number of signal sources, the number of receiving antennas, and the signal-to-noise ratio (SNR). In this study, we investigate the impact of these variations on deep learning-based AoA estimation by systematically analyzing how the variations in the characteristics of the received signal …

Examining The Influence Of Vision And Change And A Mentoring Network On Teaching Philosophies And Strategies, Stephanie Mathews, Carlos C. Goller, Michael J. Wolyniak, Uma Swamy, Anjali Misra, Michael E. Moore, Jeremy L. Hsu, Dina L. Newman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The 2011 report Vision and Change: A Call to Action (V&C) resulted from a national effort to rethink biology curriculum. V&C outlines core concepts and core competencies for biology undergraduates and promotes evidence-based pedagogy, undergraduate research, and inclusive practices. However, it is unclear how much biology educators know about V&C and what motivates educators’ development of their teaching philosophy and practices. We leveraged the Promoting Active Learning and Mentoring (PALM) Network, a group that introduced evidence-based instructional practices (EBIPs) to instructors through mentoring, journal clubs, and a community of practice, to investigate how much V&C has influenced educator …
