An Integrated Multivariate Econometric Modeling Framework For Risky Driving Behavior Related Crashes: Evaluating Crash Risk And Severity Across Zones, Pabitra Kumar Roy

Dissertations and Theses

Rapid advancements in crash modeling have yet to fully integrate multiple behavior-driven crash types and their severity outcomes within a single, scalable framework, specially in a way that captures the sequential nature of these behaviors where one risky action may amplify another. This study proposed an integrated multivariate econometric framework to jointly model crash frequency and severity outcomes for three major behaviorally driven crash types: alcohol-related, distraction-related, and aggressive-driving-related crashes. Specifically, using Oregon's 2022 census block group-level crash data, we propose an Integrated Multivariate Negative Binomial – Generalized Ordered Probit Fractional Split (IMNB–GOPFS) model to analyze these dimensions simultaneously while …

Macroinvertebrate Community Dynamics In A Recovering, Hypersaline Estuary, Catherine M. Eckert, Claudia A. Tamez, Erin E. Easton, David Hicks

School of Earth, Environmental, & Marine Sciences Faculty Publications

The Bahia Grande is a 6,500—acre tidal basin located at the southernmost tip of Texas. Tidal flow into this coastal estuary was cut off in the 1930s, causing the basin to dry up for ~70 y. A pilot channel connecting the Bahia Grande to tidal waters was constructed in 2005, allowing flooding of the basin to occur. Throughout the period reported herein (2005–2019), the system remained characterized by persistent spatial and temporal episodes of extreme hypersalinity (>70)—a critical factor influencing estuarine community composition and driving key ecological processes. With additional rehabilitation actions forthcoming, characterization of the estuary is essential …

Perron Theorem Application To A Second-Order Differential Equation With Small Advances, Jason Hendrix

Theses and Dissertations

We analyze a delayed second order differential equation with small delay parameters, proving spectral stability via the characteristic quasi-polynomial and establishing uniform bounds on derivatives of the Green’s function to ensure sign preservation under perturbation, providing a foundation for monotone iteration methods. These results aim to advance the functional-analytic framework for traveling wave solutions in delayed reaction-diffusion systems.

The Effect Of Wearable Resistance Microloading On Sprint Biomechanics, Curtis King

Doctorate in Kinesiology

Wearable resistance refers to the practice of attaching weight to specific body segments during sport-specific movements. This study investigates the impact of progressive microloading training, which involves wearing wearable resistance on the torso (3%, 5%, 10%), on sprint mechanics and performance among competitive athletes. A total of twenty-two participants engaged in a nine-week study that included both progressed and non-progressed group protocols. Sprint times, hip angles, and perceived fatigue were monitored at pre, mid, and post-intervention. A manual biomechanical analysis combined with SPSS-based repeated measures ANOVA indicated no statistically significant changes in hip angle or sprint times between the groups. …

Playing By Feel: Gender, Emotion, And Social Norms In Overwatch Role Choice, Cristo Leon, Angela Arroyo, James Lipuma

STEM for Success Resources

This paper explores how emotion, gameplay context, and social norms shape role choice in both digital and institutional systems. Using Overwatch as a case study, it examines gendered experiences of physiological excitement and decision-making during play. Women often describe heightened emotional engagement where victory represents both personal achievement and resistance to cultural expectations. Such emotions influence situational choices, including whether to play as a Tank, DPS, or Support, and which hero to select based on perceived risk or visibility. Drawing on feminist game studies and transdisciplinary communication, the authors argue that role preference is determined not only by game mechanics …

Scout 07, Austin Roberts

Theses

Throughout my tenure at RIT, I have produced multiple short films, undertaken gaming co-ops, and pursued an independent study centered on gaming assets to expand my technical and creative skills. For my thesis film, I sought to merge these experiences by concentrating on environmental storytelling—a deliberate challenge, given faculty concerns that narratives lacking strong character focus may struggle to engage audiences emotionally. With these considerations in mind, I crafted a film featuring a secondary character within a rich environment, designed to immerse viewers and provoke curiosity about the story’s temporal and spatial context.

Global Carbon Mitigation From Bacnet Adoption In Commercial Building Automation Systems 1995-2030, Fei Han, Weiwei Mo

Building Automation Systems (BAS) play a critical role in improving energy efficiency in commercial buildings, yet their long-term carbon mitigation potential has not been comprehensively quantified at a global scale. As the dominant open communication standard enabling interoperability in modern BAS, BACnet has played a central role in expanding automation adoption worldwide. This study develops a cohort-based modeling framework to estimate historical (1995–2025) and projected (2026–2030) CO₂e mitigation from BACnet-based BAS adoption across four regions: the United States, Canada, Europe, and the Rest of World (ROW). The model combines regional commercial floor area, baseline electricity and natural-gas energy intensity, BAS …

Evaluation And Calibration Of Coupled Low-Cost Particulate Matter Sensors, Tyler Cargill

McKelvey School of Engineering Graduate Student Theses & Dissertations

Low-cost sensors (LCS), if used appropriately, are useful instruments to elucidate human exposure to particles suspended in the air (i.e. particulate matter, PM). Characterizing this exposure is crucial, as exposure to PM2.5 (i.e. particles with aerodynamic diameter ≤ 2.5 μm) negatively affects the respiratory, cardiovascular, and other organ systems and is the leading environmental burden for global mortality. Similarly, exposure to particles with aerodynamic diameters greater than 2.5 μm and less than or equal to 10 μm, here forth termed as PMCoarse, is known to cause health ailments for the upper respiratory system. This dissertation focuses on the MODULAIRTM-PM (MOD-PM), …

Investigating Metabolic Heterogeneity In Engineered Isogenic Microorganisms, Xinyue Mu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Engineered microorganisms play an increasingly important role in the sustainable production of fuels, bioplastics, and other valuable biomaterials. Successful industrial deployment depends on maximizing product titers and ensuring process robustness at large scale. However, one of the major obstacles is non-genetic cell-to-cell heterogeneity arising from stochastic intracellular processes. Such heterogeneity can result in subpopulations that divert substrates toward growth rather than product biosynthesis, ultimately reducing yield and contributing to batch-to-batch inconsistency. To better understand the mechanisms by which cell-to-cell variation emerges, propagates, and impacts bioproduction, this dissertation investigated how intracellular energetic dynamics and stochastic biosynthetic noise contributed to metabolic heterogeneity …

Transforming Co2 Into Value-Added Products: Liquefied Petroleum Gas And Solid Carbon Materials, Kaiying Wang

McKelvey School of Engineering Graduate Student Theses & Dissertations

The escalating climate crisis, driven by anthropogenic carbon dioxide (CO2) emissions, necessitates the development of advanced Carbon Capture and Utilization (CCU) technologies. A critical distinction within CCU lies between transient carbon cycling, which converts CO2 into fuels, and permanent sequestration, which transforms it into durable, solid materials. This dissertation addresses fundamental catalytic challenges across both pathways to develop economically viable and technologically sound solutions for CO2 valorization. This work seeks to answer two primary research questions: (1) How can the catalyst temperature mismatch and stability limitations in the tandem conversion of CO2 to Liquefied Petroleum Gas (LPG) be overcome to …

Late-Stage Capitalism And Consumerism In Higher Education: A Morphogenetic Analysis, Kallen Zhou

Publications

Facing widespread student disengagement and dissatisfaction, U.S. higher education is undergoing a paradigm shift, detaching from its civic and pedagogical origins. A key force driving this transformation is the rise of student consumerism. While existing literature documents market-driven actions adopted by higher education institutions (HEIs) and the consumer roles students play, it overlooks structural market forces. Specifically, little theorization exists on the relationship between late-stage capitalism and student consumerism. This paper addresses that gap through two steps: first, offering a historical analysis of the traditional university model, late-stage capitalism, academic capitalism, and the decline of the liberal arts; second, developing …

Amp: Single-Shot Ultra-Wide Fisheye-To-Cubemap Pnp Pose Estimation, Ryan M. Raettig, Richard R. Nyquist, Scott L. Nykl, Clark N. Taylor, Christine M. Schubert Kabban

Faculty Publications

Estimating the position and orientation of a rigid object from an image is critical for situational awareness in robotics and autonomous systems. This study explores relative pose estimation using an ultra-wide fisheye camera for unmanned aircraft inspection vehicles. Ultra-wide fisheye lenses introduce radial distortion and capture features beyond the rectilinear image plane, rendering rectilinear Perspective-n-Point (PnP) algorithms inadequate. Designing a bespoke ultra-wide fisheye localization algorithm requires consideration of both the feature detection method and the pose estimator itself. This study proposes a novel method that combines (1) a fisheye-to-cubemap reprojection, (2) a You Only Look Once (YOLO) convolutional neural network …

Thematic analysis shows that Danu Kerthi continues …

Investigate The Role Of Tgfβ3 In Regulating Irf6 And Δnp63 In Periderm Desquamation, Nam Ha

Theses & Dissertations

Introduction: Failure in palatal fusion during palate development results in cleft palate, one of the most common birth defects in the US. During the final phases of palatogenesis, the palatal periderm (a protective cell layer that prevents premature fusion and adhesion with oral epithelium) must be removed, also known as desquamation. This process is a prerequisite for establishing the midline seam in the fused palate. Previous studies have shown that transforming growth factor-β3 (TGFβ3) plays an irreplaceable role in palate development in mice. Our previously published mechanistic models outline the role of TGFβ3 and its downstream signaling cascade involving proteins …

Assessment Of Polymeric Chloroquine Formulations For Targeted Therapy Of Ulcerative Colitis And Metastatic Colorectal Cancer, Neha Kumari

Theses & Dissertations

Effective targeted drug delivery is a critical unmet need in the management of both ulcerative colitis and metastatic colorectal cancer, where conventional systemic therapies may be hindered by suboptimal efficacy and significant side effects. This thesis explores the development and preclinical assessment of polymeric chloroquine (PCQ)-based nanotherapeutics, leveraging stimuli-responsive designs for disease-specific delivery and action.

For ulcerative colitis, a reactive oxygen species (ROS)-responsive nanogel system was engineered to release PCQ, a macromolecular derivative of hydroxychloroquine, specifically in the inflamed areas within the colon. Nanogels with well-defined size and positive surface charge were synthesized via reversible fragmentation chain transfer (RAFT) polymerization …

Role Of Nadph Oxidase 4 In Murine Cancer-Associated Fibroblast, Faith M. Gomez

Theses & Dissertations

Breast cancer is the second leading cause of cancer deaths in women in the United States. Frontline hormone therapies for breast cancer prove ineffective in triple negative breast cancer tumors wherein the hormones estrogen, progesterone, and HER2 are downregulated or absent; therefore, patients diagnosed with triple negative breast cancer are primarily limited to chemotherapies which carry a higher failure and resistance rate. Here we target cancer associated fibroblasts as potential drivers of chemoresistance in triple negative breast cancer. We investigated the mechanism by which Nox4 regulates the YAP/TAZ pathway in modulating DTX sensitivity and sought to determine if targeting Nox4 …

Optimal Sizing Of Battery Energy Storage Systems For Peak Shaving And Demand Response Using A Degradation-Aware Bayesian Optimization-Mixed-Integer Linear Programming Framework, Jiwei Yao, Blake Billings, Tao Gao, John Hedengren, Kody M. Powell

Faculty Publications

The increasing integration of renewable energy and rising electricity demand highlight the importance of battery energy storage systems for peak shaving and demand response. Unlike prior approaches that overlook operational impacts on degradation, this study proposes a Bayesian Optimization–Mixed Integer Linear Programming framework for optimal battery energy storage system sizing. In this framework, Mixed Integer Linear Programming determines short-term scheduling while a calibrated electrochemical model iteratively evaluates degradation. The central hypothesis is that the framework can efficiently identify optimal sizes that yield realistic and economically robust outcomes. The method is tested across three scenarios: peak shaving, peak shaving with energy-reduction …

Socrates And Early Buddhist Medical Ethics: Foundations Of Moral Reasoning In The Care Of Body And Mind, Chandima Gangodawila

Budhi: A Journal of Ideas and Culture

While Buddhist traditions articulate a parallel moral vision in the early discourses of the Pāli Canon, Western traditions usually locate the roots of ethical reasoning in Socratic inquiry. Especially in their approaches to bodily care, spiritual well - being, and moral responsibility, this article contends that both Socratic and Early Buddhist ideas converge on fundamental principles in medical ethics. Through a comparative textual and philosophical study, the paper examines how Socratic dialectics and the Buddha's diagnostic approach to dissatisfa ction/ suffering (dukkha) both produce frameworks for ethical healthcare anchored in the development of virtue, wisdom, and care for the integrity …
