A New Model For Predicting Two-Zone Parameters Based On Geometric Modifications In Computational Fluid Dynamics Simulations, Jason B. Metten

Theses and Dissertations

This study uses Computational Fluid Dynamics (CFD) to create a new and improved model for key Two-Zone modeling parameters, 𝜒 and 𝛿2𝑝. It explores how geometric changes to centrifugal compressors impact these modeling parameters. While centrifugal impellers are an important part of many systems, the flow through such impellers is inherently complex, making performance often difficult to predict. There are many approaches for modeling this complex flow environment, one method being the Two-Zone model developed by Dave Japikse. Values for 𝜒 and 𝛿2𝑝 are often determined from data obtained from test rigs or correlations. In this study high-fidelity CFD simulations …

Challenging Batson: Interest Convergence And Permanence Of Racism In Jury Selection, Addrain Conyers, Amanda Bergold, Antoinette Critelli

The Scholar: St. Mary's Law Review on Race and Social Justice

A Batson challenge is an objection to the use of peremptory challenges to dismiss potential jurors based on their race; however, Batson challenges are rarely successful. In this paper, we apply Critical Race Theory (CRT) as a framework to analyze the Batson Challenge. More specifically, we argue that the Batson challenge is a practice grounded in interest convergence that underscores the permanence of racism in the judicial system. We explore three interests of Batson: (1) the protection of the Sixth Amendment right to a fair trial; (2) the protection of the Fourteenth Amendment; and (3) the promotion of public trust …

From Fear To Familiar: Decreasing Technology Anxiety Among Older Adults In A Senior Community, Regina Rayz

Master's Projects and Capstones

Objective: Older adults (defined by the WHO as those 65 and older in developed countries) are more susceptible to technophobia than younger adults (Song et al., 2025). The fear and anxiety occurs with use of smartphones, tablets, social media, and telehealth and is associated with higher rates of social isolation and reduced autonomy. Technology-use anxiety is a preventative obstacle that inhibits both technology acceptance as well as overall health (Kim et al., 2023). Aim: To reduce technology-related anxiety among older low-income adults living in a senior residential facility in Richmond, CA by at least 25% using a brief, individualized technology …

Dem Simulations For Tractive Performance Of Rigid Wheel In Granular Media, Aidan Noah Dickerson

Theses and Dissertations

Accurately predicting vehicle mobility in granular media is essential for evaluating off-road mobility in agriculture, defense, and planetary exploration. Traditional empirical models often fail in capturing complex micromechanics of soil deformation, especially under dynamic conditions such as high slips and maneuvering. This study demonstrates the value of the discrete element method (DEM) in modeling wheel-soil interactions with higher fidelity. Using Altair EDEM and pre-calibrated GEMM materials, simulations were conducted for a range of forward (-5.9% to 54.8%) and side slip angles (3°, 6°, 12°) in dry sand. DEM enabled detailed analysis of sinkage, traction forces, and lateral loads, revealing trends …

Electrospun Nanofiber Creation With Varying Polymer-Solvent Combinations For Air Filtration, Lancaster Jace Hill

Theses and Dissertations

This study aims to analyze various polymer-solvent combinations for electrospun creation of nanofiber media and to determine the best-suited solution for lab-grade electrospinning. Suitable solutions allow for controlled morphology of fiber diameters and for efficiency of media creation. The principal variables are solvent, concentration, and voltage. Humidity and temperature play a secondary variable role. The solution must withstand an electric field of ≤30 kV and be insoluble in water to maintain desired morphology and structure. Manipulation of the solutions and variables allow for fiber diameter optimization and beading minimization. High temperature filter applications require efficiency in intense heat and preservation …

Toward A Unified Network Flow Framework: From Conservation Principles To Fluid Dynamics Models, Zonghan Zhang

Theses and Dissertations

Network flows govern a wide range of critical systems, from tangible infrastructures like transportation and power grids to replicable processes such as information spread and epidemics. While tangible flows obey conservation laws and physical constraints, replicable flows, like rumors or viruses, can grow, decay, or vanish unpredictably. Despite their increasing interaction in real-world settings, these flow types are typically modeled in isolation, using disconnected mathematical frameworks. This dissertation presents a unified modeling approach that bridges the gap between conserved and replicable flows by embedding principles from fluid dynamics into graph-based propagation models. I introduce physically informed extensions to classical models, …

Thomas, Kristina Pattison, Suneel Kumar, Gagana Karkada, Duncan Trosan, Aunic Goodin, Jason Rainone, Dnyaneshwari Rananavare, Vandana Miller, Francois Berthiaume, Katharina Stapelmann

Kimmel Cancer Center Faculty Papers

Cold atmospheric plasmas (CAP) are a versatile tool in medical applications like wound healing. Its therapeutic benefits are partially attributed to the generation of biologically active reactive oxygen and nitrogen species (RONS). Characterization of RONS, however, typically only occurs after treatment. Here we report the first real-time in situ detection of CAP-generated nitric oxide (NO), and the simultaneous detection of cellular calcium ions (Ca²⁺) release using electrochemical sensors during CAP treatment of murine wounds. In vivo, NO rose rapidly within the first minute of CAP treatment but accumulated less overall than in PBS, reflecting reactions with wound-bed targets. In situ …

Conservation Of Cis-Regulatory Codes Over Half A Billion Years Of Evolution, Yohey Ogawa, Yu Liu, Connie A Myers, Ala Morshedian, Gordon L Fain, Alapakkam P Sampath, Joseph C Corbo

2020-Current year OA Pubs

Identifying homologous cell types across species is essential for understanding cell type evolution. The retina is ideal for comparative analysis because its six major cell classes have persisted since the origin of vertebrates more than half a billion years ago. Here, we show that the retina's conserved cellular architecture is mirrored by deep conservation of the cis-regulatory codes that govern gene expression. Through single-cell chromatin accessibility analysis of lamprey, fish, bird, and mammalian retinas, we demonstrate cross-species conservation of cis-regulatory codes in all retinal cell classes despite extensive turnover of cis-regulatory regions. Conservation manifests as clustering of high-affinity transcription factor …

An Axe To The Funny Bone: Curated Instability And Horror-Comedy Intersections In American Storytelling, Samantha Box

Masters Theses

Funny. Terrifying. Subversive.

Horror-Comedy twists and bites at the intersection of two incredibly reactive genres— with both Horror and Comedy being well known for the political and social discourses they embody and reinvent through story. While prevalent in American popular culture, scholarly analysis of this hybrid space barely exists beyond a small number of Film Studies investigations. Despite this lack, Horror-Comedy works continue to be successfully produced. This thesis unpacks the vibrant relationship between fear and laughter in contemporary American storytelling through Horror-Comedy, maintaining a focus on structural dynamics and the audience-disarming results of simultaneously applying horror and humor to …
