Development Of A Low-Cost Roadside Monitoring System For Identifying High-Emitting Heavy-Duty Trucks, Spencer Larson
Development Of A Low-Cost Roadside Monitoring System For Identifying High-Emitting Heavy-Duty Trucks, Spencer Larson
Theses and Dissertations
This project investigated the feasibility of using low-cost sensors to identify high-emitting heavy-duty diesel trucks through roadside emissions monitoring. A sampling system was designed and tested in both laboratory and field environments to evaluate sensor performance and measurement reliability. In the laboratory, controlled engine testing enabled direct comparison between low-cost sensors and research-grade instruments to establish baseline accuracy, response time, and sources of uncertainty. These tests demonstrated that while low-cost sensors exhibit greater bias and slower response, several are capable of detecting transient emission events. Field deployments revealed that real-world conditions, such as plume dilution, spatial variability, and short exposure …

Wounded Domestic Ecologies: Ecofeminist Readings Of Gendered Trauma In Purple Hibiscus, Erere Victory Iwhi
Wounded Domestic Ecologies: Ecofeminist Readings Of Gendered Trauma In Purple Hibiscus, Erere Victory Iwhi
Theses and Dissertations
This thesis examines Chimamanda Ngozi Adichie's Purple Hibiscus through an ecofeminist and postcolonial ecocritical lens, developing the concept of "wounded domestic ecology" to analyze how gendered violence operates within domestic space. Drawing on trauma studies, particularly J. R. Kurtz and Rob Nixon's concept of slow violence, it argues that harm in the novel is accumulative, produced through repetition, surveillance, ritual, and spatial regulation. Eugene's household functions as an environment that disciplines bodies, governs language, and embeds fear into everyday life. In contrast, Aunt Ifeoma's home in Nsukka offers a counter-ecology structured by sound, shared labor, and dialogic authority, interrupting the …

Discovery Of Bmi-Associated Gut Microbiome Signatures In The Awi-Gen 2 Cohort, Meriem Yagoubi
Theses and Dissertations
Obesity is increasing across sub-Saharan Africa amid rapid dietary, environmental, and urbanization transitions, yet the gut microbiome features associated with adiposity in African populations remain under-characterized. This study investigated whether species-level gut microbiome composition is associated with body mass index (BMI) in the AWI-Gen 2 cohort, and whether BMI-associated microbial signals remain detectable after accounting for the dominant geographic structure of the microbiome. Gut microbiome community structure and diversity were characterized across 1,665 participants, and differential abundance analysis was used to identify taxa associated with BMI after controlling for study site. Machine learning models were then trained to assess how …
Storytelling, Gender, And The Double-Empathy Problem, Annie Rogers
Storytelling, Gender, And The Double-Empathy Problem, Annie Rogers
Theses and Dissertations
Storytelling has been proposed as a meaningful way to facilitate empathy and connection, particularly across neurotypes. The present study examined whether a live storytelling event influenced perceptions of the autism community, empathy, and interpersonal connection, while also exploring differences on biological sex and levels of autistic traits. Participants completed pre- and post-event measures assessing relationship perceptions and connection, along with standardized measures of empathy and autistic traits. Results showed a significant increase in positive perceptions of the autism community and perceived closeness to storytellers after the event. Engagement, emotional impact, openness, and motivation to support the autism community were all …
Modeling The Spread Of Competing Narratives In Multimodal Social Media Network, Mayor Inna Gurung
Modeling The Spread Of Competing Narratives In Multimodal Social Media Network, Mayor Inna Gurung
Theses and Dissertations
Social media has fundamentally transformed how narratives are produced, contested, and disseminated, enabling competing interpretations of the same event to spread rapidly across networked populations. Understanding how narratives gain traction over others in these environments is critical for addressing misinformation, supporting informed public discourse, and designing effective counter-messaging strategies. Yet existing research largely treats narrative propagation as a single-process phenomenon and focuses predominantly on textual data, overlooking both the competitive dynamics between opposing narratives and the growing role of visual symbolic communication in shaping how narratives are received. This dissertation addresses these gaps through a multi-platform, multimodal framework applied to …

Centering Well-Being And Wholeness: Exploring Racial Battle Fatigue Among Black 3-K To Twelfth-Grade Teachers, Olubunmi Fashusi
Theses and Dissertations
This qualitative case study, with some descriptive statistics, examined Black 3-K through 12th- grade teachers’ experiences with racial battle fatigue (RBF), the psychological and behavioral stress responses they perceived most accurately convey how RBF manifests for them, and the strategies they used to disrupt RBF’s impact. Participants experienced compounded RBF due to advocating for students (i.e., speaking out, supporting, or intervening). Participants’ most perceived psychological stress response to RBF was racism awareness, and most perceived behavioral stress response was spirituality or religion. Participants disrupted the impact of RBF through intrinsic care (i.e., purpose or why, managing emotions, and self-care) and …
Design And Optimization Of A Bluff Body For Energy Harvesting Of Transverse Galloping Induced By Low-Speed Wind Using Bernstein Polynomial Equations, Youssef Wael Abdelmoneim
Design And Optimization Of A Bluff Body For Energy Harvesting Of Transverse Galloping Induced By Low-Speed Wind Using Bernstein Polynomial Equations, Youssef Wael Abdelmoneim
Theses and Dissertations
In this thesis, a computational framework is proposed for optimizing the aerodynamic shape of bluff bodies used in galloping-based wind energy harvesters. The system targets low-wind speed environments, where normal wind turbines are not effective, offering a potential alternative to batteries used for powering small electronic devices such as wireless sensors. The design relies on the galloping effect, where airflow around a bluff body induces transverse oscillations that drive an energy conversion mechanism. To generate efficient bluff body geometry, the Class-Shape Transformation (CST) method is used to define a wide range of candidate shapes with minimal design parameters. These shapes …
Turning Boycott Into A Sustainable Opportunity: Leveraging Boycott To Boost Local Production And Enhance Local Market Competitiveness In Egypt, Alaa Maher
Theses and Dissertations
While existing literature largely concentrates on the consumer behavior dimensions of boycotts, limited attention has been paid to their structural economic implications for FDI and local production. This paper frames the 2023 boycott campaign as a demand shock in Egypt’s food and beverages sector. Dependency theory is applied to assess the pre-boycott stage, where MNCs’ market power created structural dependencies within the sector. Dynamic capabilities theory is employed to explain the heterogeneity in firm responses during the boycott and their attempts to acquire sustainable market share. Using a multi-case study design, qualitative in-depth interviews were conducted across 16 firms in …

The Relationship Between Musical Ability And Perceptual Skills For Speech Motor Learning In Young Adults, Emily Catmull
The Relationship Between Musical Ability And Perceptual Skills For Speech Motor Learning In Young Adults, Emily Catmull
Theses and Dissertations
Speech motor learning is the multimodal process of acquiring speech sounds. Speech motor learning is trained through speech-language pathologist intervention in individuals across the lifespan. Previous research has explored which factors can influence speech motor learning, such as musical experience or training, which is the subject of this study. Sixty young adult participants (four male, 56 female) were recruited as part of a larger study that examined four possibly influential factors: bilingualism, phonetic knowledge, perceptual skills, and musical experience. Since the adult population has already acquired all the speech sounds in English, learning was measured using nonnative consonant clusters. Participants …

Same-Subject Induction Experiences For Elementary Music Teachers: Teacher Efficacy Beliefs, Experiences Of Isolation, And Job Satisfaction, Wendy Tams Hickman
Theses and Dissertations
This survey study seeks to explain the relationships between elementary music teachers' experiences with same-subject induction support and those teachers' feelings of teacher efficacy, experiences of isolation, and job satisfaction. Independent variables came from latent class groupings of same-subject induction support for beginning elementary music teachers. Teacher background variables were also included as controls. Three- and four-step regression models helped provide understanding about how the relative set of predictors--teacher background variables, isolation levels, induction experiences, and interaction terms--predicted the three outcomes. Initial regression analyses showed that the number of years of teaching elementary music predicted efficacy and levels of isolation …
The Correlation Between Perceptual Abilities And The Acquisition Of Non-Native Consonant Clusters, Hope Emma Nielson
The Correlation Between Perceptual Abilities And The Acquisition Of Non-Native Consonant Clusters, Hope Emma Nielson
Theses and Dissertations
A common approach in the study of speech motor learning is to have speakers learn to produce clusters of consonants that do not occur in their native language. This study investigated the relationship between auditory or speech perceptual abilities and the initial acquisition of non-native stop-stop consonant clusters. Sixty young adult participants (56 female, four male) were administered a gap detection test and a speech-in-noise test to assess their innate perceptual skills. The participants then performed a nonsense-word repetition task featuring non-native consonant clusters in the initial position. The participants' spoken productions of the nonwords were recorded and analyzed acoustically …

Vigor: Virtual Intelligence For Gaze Observation And Representation, Meherun Nesa Shraboni
Vigor: Virtual Intelligence For Gaze Observation And Representation, Meherun Nesa Shraboni
Theses and Dissertations
Eye tracking in modern XR head-mounted displays can capture high-frequency gaze data at 90–120 Hz, generating thousands of samples within a single 30-second interaction. At the same time, the XR market has grown to millions of active users worldwide, with major platforms such as Meta investing heavily in eye-tracking-enabled devices. Despite this large-scale adoption and data availability, most applications still rely on hand-controller input, with gaze either processed offline or reduced to a simple pointing signal. As a result, the majority of temporally rich gaze information remains unused in real-time interaction, limiting system responsiveness, reducing interaction fidelity, and preventing effective …
The Reliability Of Yolo Object Detection On The Amd Versal In A Proton Radiation Environment, Jacob D. Brown
The Reliability Of Yolo Object Detection On The Amd Versal In A Proton Radiation Environment, Jacob D. Brown
Theses and Dissertations
Object detection is an important operation for satellites to be able to perform, and in outer-space missions it is crucial that machine learning models perform inference on satellite images accurately and reliably. Where size, weight, power, and other constraints exist, meeting this goal for accurate and reliable object detection is challenging. Additionally, soft errors caused by radiation further disrupt and degrade the operation of object detection in satellites. This thesis studies the performance of a deep learning model on an embedded device, the AMD Versal, in the presence of soft errors. The well-known and high-performing YOLO convolutional neural network was …
