Community Resilience Drives Change, Andrew Thomas Solt

Graduate Theses, Dissertations, and Problem Reports (ETD)

The opioid crisis has impacted many Americans. From 1999 to 2023, approximately 800,000 people have died due to opioid overdose (CDC, 2025). What began as overprescriptions of painkillers has quickly evolved into a complex social health issue that is now further worsened by stronger synthetic drugs like fentanyl. Fentanyl and fentanyl analogs (synthetic opioids that are very similar chemically to fentanyl) are often found in illegal drug supplies and in counterfeit pills (CDC, 2025). Thus, individuals who might have been initially overprescribed painkillers might now be pushed towards illegally produced drugs that are significantly more potent than what they were …

A Digital Calibration Source For 21 Cm Cosmology Telescopes, Kalyani Balkrishna Bhopi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Precise calibration of radio telescope beams and gains is a central requirement for 21 cm intensity mapping experiments, which aim to measure large scale cosmological structure through the redshifted emission line of neutral hydrogen. Bright astrophysical foregrounds dominate the sky at these frequencies, and separating them from the cosmological signal demands precise control over instrumental systematics, particularly the telescope beam and its frequency-dependent response. Existing aerial calibration sources are incoherent broadband emitters, detectable only as total power. They provide no direct phase information and suffer from poor sensitivity in low signal-to-noise regimes.

We present the Precision Emitter for 21cm Array …

Swarm Of One: Self-Organization In Multicellular Robots, Trevor Riley Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Designing robots traditionally relies on centralized, top-down methods that constrain adaptability and resiliency, producing systems optimized for specific tasks. However, such systems often fail in complex environments, such as extraterrestrial, disaster, or natural settings, where designers cannot foresee every scenario a robot may encounter. Achieving autonomy in these contexts requires robots that are resilient and capable of adapting to the unknown. Multicellular organisms exhibit this adaptability through self-organization, where complex structures and behaviors emerge from local interactions among their cells. Such organisms can be viewed simultaneously as a single entity and a swarm of cooperating cells, i.e., a Swarm-of-One.

Development And Validation Of A Multi-Output Neural Network-Based Virtual Temperature Sensor For Electric Vehicle Thermal Management, Dalton Michael Wiggins

Graduate Theses, Dissertations, and Problem Reports (ETD)

Battery electric vehicles (BEVs) rely on accurate thermal management to ensure component performance, efficiency, safety, and long-term durability. Critical propulsion system components, including electric motors and high-voltage battery packs, are commonly monitored using physical temperature sensors. However, these sensors increase system cost, introduce additional hardware complexity, and may be impractical for directly measuring temperatures at critical internal locations. Virtual temperature sensors (VTSs) provide a software-based alternative by estimating component temperatures using readily available vehicle operating data.

This research presents the development and validation of a long short-term memory (LSTM) neural network-based virtual temperature sensor capable of simultaneously estimating the motor …

Computer Vision Methods For Rfi Segmentation In Radio Astronomy, Yechan Kweon

Graduate Theses, Dissertations, and Problem Reports (ETD)

Radio Frequency Interference (RFI) increasingly contaminates the radio astronomy spectrum, often exceeding astronomical signal amplitudes by 50–70 dB. Reliable detection and mitigation are therefore essential for studies of faint transient phenomena such as pulsars and fast radio bursts (FRBs). Existing practical methods including Spectral Kurtosis (SK), Median Absolute Deviation (MAD), and SumThreshold perform well in many settings but depend on assumptions about the RFI environment and data statistics, limiting their effectiveness for weak, broadband, or nonstationary interference.

We develop a transform based RFI detection method that requires no prior knowledge of the RFI origin or type. The method operates on …

Students consistently valued in-person interactions over online …

Difficult Tasks And Strained Ties: Irritation As A Mediator For Relationship Quality And Caregiver Distress, Payton Elisabeth Radcliffe

Graduate Theses, Dissertations, and Problem Reports (ETD)

Caregiving, defined as providing regular unpaid assistance to individuals with chronic illness or disability, is a widespread role associated with both societal benefit and psychological strain (Berg et al., 2021; Schulz et al., 2020). Prior research indicates that perceived caregiving difficulty is a key predictor of caregiver distress, though the mechanisms underlying this association remain unclear (Blom et al., 2024; Gérain & Zech, 2022). Drawing on the Stress Process Model (Pearlin et al., 1990), the present study examined irritation as a mediator linking perceived caregiving difficulty to relationship quality and caregiver distress, while also testing whether caregiver relationship type moderates …

Carbon Emissions And Greenwashing: Do High Esg Scores Reflect Real Decarbonization?, Alison Steenerson

All Master's Theses

This study examines the relationship between environmental scores, environmental performance, disclosure quality, and firm characteristics using a sample of publicly traded firms observed in 2020 and 2021. A two-stage regression framework was used to separate environmental scores into components explained by observable environmental performance, firm characteristics, disclosure practices, and environmental commitments. Results indicate that emissions intensity has a statistically significant but economically small relationship with environmental scores. In contrast, disclosure quality measures exhibited strong positive associations with environmental scores. Firms reporting emissions, participating in CDP, disclosing emissions targets, and adopting science-based targets received higher environmental scores independent of environmental performance. …

Forecasting The Emotional Cost Of Online Dehumanization, Reyhaneh Bagherian Shamir

All Master's Theses

The use of social media platforms to share, view, and communicate information is now ubiquitous (Crockett, 2017). Given the prevalence of problematic content found on social media (e.g., prejudice, misinformation), this research examines how accurately people predict their responses to such content. Kawakami et al. (2009) found that individuals overestimate their emotional distress and behavior in response to discriminatory actions (i.e., racism) in-person predicting they would be more upset, and more likely to reject a racist confederate than individuals who experienced the incident actually were. In the current research, we built upon the work of Kawakami et al. (2009) to …

Modernism’S Wild Child: The Interplay Of Modernist And Children’S Literature, Rachel Riffel

All Master's Theses

Within literary criticism, American and British modernism are often characterized by the disillusioned writers and creators who established an elitist literary community during the early 20^th century. This period is also distinguished by the Harlem Renaissance highlighting Black art, culture, and writing. Gertrude Stein, T. S. Eliot, Langston Hughes and Arna Bontemps are well-known for contributing core texts to modernism and the Harlem Renaissance that expressed existential themes and developed experimental techniques. What many readers don’t know, however, is that these authors and many other contemporaries wrote stories and poetry for children. In this thesis, I explore the children’s …
