Evaluating The Performance Of The Primary Heat Exchanger In A Sco2 Brayton Cycle While Firing Solid Fuels, Brian Jeffrey Schooff

Theses and Dissertations

The sCO2 closed-loop Brayton cycle is an alternative to the standard steam-Rankine cycle for generating electrical power from a heat source. The sCO2 Brayton cycle is advantageous because it can be more efficient, use less water, and have smaller turbomachinery than the steam-Rankine cycle. While there are several research groups advancing the technology necessary to utilize the sCO2 Brayton cycle on an industrial scale, none of these groups use solid fuel combustion as the heat source. A Brigham Young University-led project developed and tested a pilot-scale sCO2 Brayton cycle unit (1.6 MWth) using natural gas, pulverized coal, and pulverized biomass …

Drones And The Changing Character Of War, Erik A. Davis

The US Army War College Quarterly: Parameters

Cheap drones have transformed the character of war by creating a “mass effect” that challenges traditional principles of force concentration. Unlike commentary focused on offense-defense debates or ethics, this article explains how Jevons’s Paradox, the Red Queen Effect, and models like Lanchester’s Laws and Hughes’s Salvo Equations underpin this shift. Drawing on lessons from Ukraine, historical theory, and production trends, it explains why the production of cheap “precision mass” is expected to accelerate. For military and policy practitioners, the analysis offers urgent guidance for adapting tactics, procurement, and doctrine to a battlefield dominated by ubiquitous, low-cost drones—before adversaries exploit this …

Basic Science Engineering

In this work, a sixth–order extension of the nonlinear Schrödinger equation (NLSE) within its integrable hierarchy is investigated to model higher–order nonlinear and dispersive effects relevant to optical fiber systems and nonlinear wave propagation. By employing the Improved Modified Extended Tanh Function Method, a comprehensive family of exact analytical solutions is derived, encompassing bright and dark solitons, singular soliton structures, and singular periodic solutions. In addition, solution families expressed in terms of Jacobi elliptic functions, Weierstrass doubly periodic elliptic functions, and exponential profiles are obtained. The novelty of this study lies in extending the analytical framework of the NLSE hierarchy …

Mechanistic Roles And Design Criteria For Catalysts In Lithium–Sulfur Batteries, Saheed Lateef, Golareh Jalilvand

Faculty Publications

Catalysis is widely explored in lithium–sulfur (Li–S) batteries to address challenges related to limited capacity and cycle durability. Despite extensive research, catalyst development has often focused on materials without a clear understanding of the mechanistic landscape underlying the complex, multi-step, multi-electron sulfur redox pathway. In fact, our understanding of the thermodynamic, kinetic, and mass transport framework in Li–S systems is still evolving, particularly with respect to the reaction pathways during charge and discharge, and the dynamic evolution of materials in both liquid and solid phases. These evolving insights may fundamentally shift the requirements for catalyst design and future research priorities. …

Degrees Of Rate Control And Autodiff-Driven Direct Sensitivity Analysis In Heterogeneous Catalysis, Olajide H. Bamidele, Sina Behtash, Mubarak Bello, Andreas Heyden

Faculty Publications

Despite the wide application and benefits of the degree of rate control (DRC) analysis, several details remain argued, particularly about the conservation of DRCs at transient (TR) and steady-state (SS) conditions, especially for complex reaction networks. This work argues that previous proofs about the conservation properties of DRCs have been incomplete, and we provide new mathematical proofs at TR and SS conditions. In addition, we use both analytical (automatic differentiation) and numerical (finite difference) approaches to compute DRCs for the case study of ethane hydrogenolysis (EH) over Pt(111). This work confirms that at both TR and SS conditions, the sum …

Theses and Dissertations

Pancreatic cancer remains one of the most lethal malignancies, with a five-year survival rate below 5%. While rapamycin (Rap) has demonstrated therapeutic potential, its clinical utility is hampered by systemic toxicity. To address this limitation, this study developed a targeted nanocarrier system using gold nanospheres (AuNPs) functionalized with the Epidermal Growth Factor Receptor (EGFR) peptide GE11 for the specific delivery of Rap to pancreatic cancer cells. It is to note that pancreatic cancer overexpresses EGFR. The AuNP–GE11–Rap conjugates were successfully synthesized and characterized using physico-chemical techniques, which confirmed peptide conjugation and drug loading. In vitro studies using PANC-1 cells demonstrated …

Integrating nephelometers are key instruments for quantifying aerosol light scattering, a fundamental parameter governing the direct radiative effect of aerosols on climate and visibility, and for interpreting satellite observations of aerosol optical depth. The AirPhoton integrating nephelometer quantifies aerosol light scattering by measuring total scattering from the sample air and subtracting a clean-air reference that represents Rayleigh scattering, instrument wall scattering, and detector background noise. Measurement accuracy depends on rigorous calibration and regular performance evaluation to account for instrumental drift and environmental influences. This study presents a field performance evaluation of the AirPhoton integrating nephelometer within the global Surface Particulate …

Integrating Large Language Models And Single-Cell Omics Analysis For Target Discovery In Pancreatic Ductal Adenocarcinoma, Zixi Xu

McKelvey School of Engineering Graduate Student Theses & Dissertations

The elucidation of cell-type–specific signaling networks is central to understanding pancreatic ductal adenocarcinoma (PDAC) and to nominating mechanistically grounded therapeutic targets. We present a Text-to-Target framework that integrates large language models (LLMs) with single-cell omics to couple literature-derived hypotheses to cell-type–resolved expression evidence. Using publicly available datasets, we construct malignant ductal epithelial and lineage-matched acinar meta-cell cohorts from PDAC and perform differential expression analysis to obtain a robust catalogue of disease-associated transcriptional changes. In parallel, an ensemble of LLMs is prompted in a schema-constrained manner to retrieve cell-type–specific targets, pathways, and mechanistic annotations from the biomedical literature. After normalization and …

Behavior Analytic Food Reinforcement Use And Guidelines In Interventions For Children With Autism, Christopher Rogers

Electronic Theses and Dissertations 2020 - Present

Reinforcers create opportunities to increase behaviors in applied behavioral analysis, with healthy and unhealthy foods offering high reinforcing value. The use of food raises ethical and health concerns, so researchers and behavior analysts often avoid food reinforcement altogether. Kronfli et al. (2024) indicate healthy food alternatives bring about similar rates of responding as snack foods, potentially reducing ethical and health concerns. This research presents the question: To what degree are food reinforcers used in behavioral interventions for children with autism spectrum disorder? This review analyzes behavioral research articles containing the words “food,” “edible,” “autism,” and “children” in the context of …

Tests Without Borders: A Global Approach To Measuring Visualization Literacy, Olivia A. Guess

McKelvey School of Engineering Graduate Student Theses & Dissertations

Visualization literacy assessments shape how we understand people's ability to interpret data, yet most existing instruments embed Western datasets and assumptions that limit their relevance for global audiences. This thesis argues that because data is personal, assessments must also be culturally grounded. We introduce a unified framework for adapting the Mini-VLAT into 22 regionally responsive short-form assessments, each retaining the structure of the original test while incorporating datasets and scenarios tailored to specific regions around the world. To demonstrate how such adaptations can be customized and validated, we present a detailed case study of a Ghana-adapted Mini-VLAT, developed in collaboration …

Ultra-fast and precise (ps-ns) timing fluorescence acquisition techniques suffer from different trade-offs. Some methods suffer from high dead times, decreased accuracy in fluorescence lifetime calculations, and high data volumes and transfers. Finding a new method that can provide the best performance while experiencing low dead times, adequate …

Expansion Limits Of Meshed Split-Thickness Skin Grafts, Haomin Yu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Split-thickness skin grafts are widely used to treat chronic wounds. Procedure design requires surgeons to predict how much a patch of the patient's own skin expands when it is meshed with rows of slits and stretched over a larger wound area. Accurate prediction of graft expansion remains a challenge, with current models overestimating the actual expansion, leading to suboptimal outcomes. Inspired by the principles of mechanical metamaterials, we developed a model that distinguishes between the kinematic rearrangement of structural elements and their stretching, providing a more accurate prediction of skin graft expansion. Our model was validated against extensive data …

Development Of A Multispectral Collagen Detection Dermatology Device For Delineation Of Non-Melanoma Skin Cancers, Anmol Jarang

McKelvey School of Engineering Graduate Student Theses & Dissertations

To diagnose and manage skin disease, clinicians primarily use visual inspection aided with dermatoscopes, which are cross-polarized magnifiers. In recent years, digital cross polarized multispectral imaging systems have been developed to quantitatively assess skin disease. For example, systems like the one developed by Yaroslavsky et al., which utilize red and blue filters, can non-invasively assess the collagen network in the dermis(Yaroslavsky et al., 2003). Visualization of collagen network disruption can make it easier to visualize the boundaries of skin cancers like keratinocyte carcinoma, and therefore easier to excise completely. Current systems use external bandpass filters in front of cameras to …
