Progress Towards Confinement Of An Ultracold Neutral Plasma With Electric And Magnetic Fields, Ben Farley

Theses and Dissertations

Ultracold neutral plasmas represent a regime of plasmas that is not entirely described by theory, but is critical to our understanding of many phenomena. Though their low temperature makes observing them more manageable, even "confined" ultracold plasmas do not remain contained for more than a few hundred microseconds. No steady state or long-term confinement of an ultracold plasma created by pulse ionization has ever been demonstrated. In this thesis, the construction of a Penning trap for calcium ultracold neutral plasma is presented. The trap consists of a uniform magnetic field to trap the electrons radially and a quadrupole electric field …

A C++ Library For Turbulent Mixing Simulation Using Hierarchical Parcel Swapping (Hips), Masoomeh Behrang, Tommy Starick, Heiko Schmidt, David O. Lignell

Faculty Publications

Turbulence models are crucial for simulating flows at all scales, capturing both large-scale structures and small-scale mixing. Software libraries that implement such models should support modular integration, customization, and scalability across different simulation frameworks. This paper presents Hierarchical Parcel Swapping (HiPS), a C++ library documented with Doxygen and available on GitHub. HiPS supports both mixing and reactions and can be used as a standalone model or as a subgrid model in CFD simulations. The code includes examples for users to run it as a standalone model. Additionally, considerations for using it as a subgrid model are provided.

Bacterial infections continue to drive the need for more effective and rapid methods for bacterial analysis. To address this, magnetic nanoparticles (MNPs) have emerged as promising tools, especially when their surfaces are modified with bacteria binders. The bis-zinc–dipicolylamine (Zn–DPA) complex is known for its broad affinity to bacteria. We have synthesized MNPs via a thermal decomposition method, encapsulated them in silica, modified their surface with Zn–DPA, and tested their ability to remove bacteria. The MNPs retain their superparamagnetic properties and crystallite structure after being encapsulated. The MNPs coated with silica and Zn–DPA effectively bind and remove both Gram-positive and Gram-negative …

Resisting Islamophobia: “Westophobia” In Social Media, Peter O'Brien, Jordan Nelson

Comparative Civilizations Review

Both the practice and study of Islamophobia repose on the concept of comparative civilizations. Purveyors of Islamophobia use what Roger Westcott calls a “denotative” understanding to posit an objective conflict (or “clash” à la Samual Huntington) between Western and Islamic civilizations. Scholars who analyze Islamophobia tend to take what Westcott calls a “connotative” approach that views civilizations as subjective, social constructs (à la Edward Said’s “Orient”).

Despite many advantages, the latter approach tends to dismiss the agency of Muslims to resist Islamophobia. This article counters that trend by exploring Islamist resistance to Islamophobia, to which we give the shorthand label, …

Academic Civilization: Expansion And Development, Inbar Gotlib Gotlib-Rivkin

Comparative Civilizations Review

The concept of academic civilization was developed out of and in relation to that of modern civilization. Prominent characteristics of modern civilization are reflected in institutions of higher education, and they can therefore be regarded as constituting a civilization. The six main characteristics of institutions of higher education that render them a civilization include expansion in terms of scope and growth, flexibility and institutional diversity, center-periphery relations, academic culture, autonomy and academic freedom, and the monopolization of professional training and the professional middle class. This paper addresses the first characteristic — expansion of institutions of higher education — and …

Towards The Systematic Cross-Civilizational Comparison: How Civilizations Work - Case 1: The Monotheistic Civilization, Liah Greenfeld

Comparative Civilizations Review

The purpose of this essay is to offer several hypotheses based on the concept of civilization and the conceptual scaffolding for the study of the cultural reality, proposed in the Spring 2024 CCR paper, regarding the three civilizations coexisting in the world today: the monotheistic, the Sinic, and the Indic. It introduces the modal dimensions along which civilizations may differ on the level of the individual mind — cognitive (pertaining both to the structure and contents of thought), moral, and emotional; and that of the society (separate institutions and institutional systems) and history.

Intellectual Risk-Taking And Emotional Intelligence In Educational Systems: A Comparative Study Of The Usa, Finland, Japan, And Singapore, Peter Hecht

Comparative Civilizations Review

This paper examines how intellectual risk-taking (IRT) and emotional intelligence (EI) are integrated into educational systems in the United States, Finland, Japan, and Singapore, arguing that these factors are essential for fostering creativity, resilience, and academic success. In modern pedagogy, IRT is defined as the willingness of students to engage in challenging academic tasks despite potential failure, thereby promoting innovative problem-solving and critical thinking (Beghetto 210; Dweck 6). Complementarily, EI — an individual’s capacity to recognize, understand, and manage emotions — plays a crucial role in classroom dynamics by enhancing self-regulation and interpersonal relationships (Goleman 43; Mayer et al. 197). …

The Fragrance Muse: Musk As A Symbolic Tapestry In Classical Persian Poetry, Akbar Shirini, Shen Xudong, Zhao Dan

Comparative Civilizations Review

This paper explores the symbolic representation of musk in classical Persian poetry, uncovering its role as a multifaceted emblem of Iranian cultural identity and human experience. Drawing on a qualitative analysis of primary texts from the Ganjoor archive and secondary sources, the study traces musk’s historical significance across China, Iran, and Islamic world. In China, musk is prized for its rarity, medicinal properties, and metaphysical roles; in Iran, it intertwines with mythology, Zoroastrian cosmology, and trade; in Islamic contexts, it holds commercial and therapeutic value, cherished by figures like Mohammad. Within Persian poetry, musk transcends its material origins, symbolizing blackness …

Wind Turbine Rotor Design Using High-Fidelity Aerostructural Optimization, Marco Mangano, Sicheng He, Yingqian Liao, Denis-Gabriel Caprace, Andrew Ning, Joaquim R. R. A. Martins

Faculty Publications

Large wind turbines yield more energy but demand careful aeroelastic blade design. Coupled multiphysics design strategies can reduce wind energy costs exploiting fluid-structure interactions. This work presents the first high-fidelity aerostructural optimization study of a large wind turbine rotor.We use blade-resolved fluid dynamics and structural solvers in a monolithic gradient-based optimization framework to explore steady-state torque and blade mass trade-offs. The coupled-adjoint approach computes gradients efficiently, enabling the optimization of over 100 structural and geometric parameters simultaneously. Our optimization study modifies a DTU 10 MW benchmark with a simplified structure and isotropic material properties. The tightly coupled optimizations increase torque …

Using Novel Technology And Sensemaking In The Classroom, Reu/Fri Program Physics And Astronomy, Julio Escobedo

Student Works

This project looked into the usefulness of various new and unique technologies in a science classroom setting to allow for more sensemaking to occur among students. This was done through professional developments or training for multiple educators on how to use these devices in the classrooms. We found that each new technology had a unique set of useful capabilities and drawbacks. These findings suggest that implementation of these technologies can increase sensemaking if done properly and with proper training beforehand.

Cost-Effectiveness Model For Reservoir Sediment Management Economics, Connor Ronald Hale

Theses and Dissertations

Reservoir sediment deposition poses a challenge to sustainable water supplies around the world. Sediment management has proven to be an expensive endeavor. Two models have been developed to guide economic analysis for reservoir sediment management, namely the Reservoir Sediment Economics Model (RSEM) and the Reservoir Conservation Model 2 (RESCON 2). While these are helpful tools for benefit-cost prefeasibility studies, they rely heavily on sometimes elusive estimations of the benefits of water supply. In this study, a new method for economic analysis is proposed that foregoes benefit-cost analysis in favor of a cost-effectiveness approach. The Sediment Management Cost-Effectiveness Model ranks sediment …

Investigation Of A Stable And Saturated Reference Electrode Using Metal Chlorides And Oxides In Eutectic Licl-Kcl Molten Salts, Carlos Mejia, Devin Rappleye

Faculty Publications

Stable and reproducible reference electrodes (REs) are essential for electrochemical systems operating in high-temperature molten salts, where consistent control of potential is required. This study uses three different solutes to investigate the development and evaluation of REs in eutectic LiCl-KCl at 773 K. The solutes tested were NiCl2, AgCl, and NiO, each prepared at multiple concentrations to assess stability, reproducibility, and saturation. Electrochemical stability was measured over three days using chronopotentiometry (CP), followed by open circuit potential (OCP), with cyclic voltammetry (CV) also integrated to monitor changes in electrochemical behavior over time. The CP-OCP approach established a Li+/Li redox potential, …

Across multiple measurement campaigns and modeling efforts, the work integrates advanced array signal processing, high-fidelity field measurements, and improved empirical methods to expand the physical understanding of source …

Seating Charts, Connections, And Fostering Community, Mckenna B. Chow

Theses and Dissertations

This thesis explores how fostering stronger connections in the high school ceramics classroom can create a more inclusive and collaborative community. I regularly changed seating charts to encourage new relationships and strengthen classroom culture as part of this effort. Historically, seating charts have enforced uniformity and promoted specific behaviors. My research challenges these traditional purposes and proposes that seating arrangements can instead serve a more meaningful and enduring goal: promoting connection and ensuring that all students feel seen. I found that while seating charts can contribute to this goal, achieving genuine connection and inclusivity also requires several additional factors to …

Evaluating Nfl Quarterback Decision Making Through Tracking Data, Jesse N. Melville

Theses and Dissertations

Quarterback decision-making is one of the most critical determinants of success in the National Football League (NFL), yet traditional statistics fail to account for the spatial, temporal, and contextual factors influencing each play. This thesis proposes a data-driven methodology for evaluating quarterback decisions using NFL player tracking data from the 2022 season. We replicate and extend the DeepQB framework by training deep learning models to estimate expected completion probabilities and expected yards gained for each receiver at the moment of the throw. Our extension applies the approach to a newer dataset with additional contextual features, enabling a more detailed evaluation …

The Association Of Anxiety, Familial Dysfunction, And Child Emotion Regulation Between Family Therapy Sessions 1 And 4, Kaelie Noel Lemmon

Theses and Dissertations

Few studies address how relational factors may be interdependent and impact child-focused problems that could be collectively addressed in systemic family therapy. The current study utilized a cross-lagged panel model to explore the associations of parental anxiety, familial dysfunction, and child emotion regulation between four family therapy sessions. The study included 224 parents who sought family therapy and participated in the Marriage and Family Therapy Practice Research Network (MFT-PRN). Data were collected at two time points across four family therapy sessions. The findings indicated that higher levels of parental anxiety at intake were associated with higher familial dysfunction at session …
