Computational Fluid Dynamics Based Optimization Method Applied To Hydrokinetic Turbine Devices, Stuart Glenn Fletcher

Graduate Theses and Dissertations

This thesis presents a computational investigation of optimal kinematic operating parameters governing various hydrokinetic turbines (HKT) systems for the use of power generation within river and tidal environments. Two separate studies are performed. The first study investigates optimal cycle parameters for simple and complex kinematic modes governing the motion of oscillating foil energy harvesters (OFEH). An iterative gradient-ascent optimization method is used to search for local efficiency optima based on an initial set of kinematic parameters. To search the operational space for up to eight degrees of freedom (DOF), a maximin space filling condition was implemented to efficiently compute initial …

Validation Studies Of A Dynamic Hybrid Rans-Les Turbulence Modeling Strategy For Cfd Simulation Of Gas Turbine Component Film Cooling, Cole Simmonds

Graduate Theses and Dissertations

Computational prediction of the flow physics associated with gas turbine film cooling is important for ensuring effective heat transfer design. These flow fields are highly turbulent and anisotropic, making the accuracy and efficiency of the chosen turbulence model an important aspect of performing high quality computational fluid dynamics (CFD) based analysis. Current industry standard Reynolds-averaged Navier-Stokes (RANS) turbulence models such as RANS k-ω SST, while computationally efficient, are subject to relatively high levels of uncertainty in their ability to predict these turbulent flow fields. In contrast, high fidelity methods such as Large Eddy Simulation (LES) are computationally very expensive, while …

Is Artificial Intelligence Really Taking Our Jobs?, Francesca A. Strom

Undergraduate Theses and Capstone Projects

This paper studies how artificial intelligence has reshaped occupational opportunities in the United States by analyzing changes in employment, median wages, and wage inequality across all occupations from 2014 through 2024. Using a difference-in-differences framework, I compare occupations associated with AI-related tasks to those not directly exposed to generative AI, with particular attention to the structural break introduced by the mainstream release of generative AI tools in 2022. The results show no statistically significant decline in employment among AI-exposed occupations, indicating that early adoption did not lead to measurable job displacement. Instead, the strongest effects appear in wage inequality. Among …

Optimal Control Of Human Exercise Using An Individualized Physiological Three-Tank Model And Dynamic Programming, Asal Lotfi

All Theses

This thesis develops a physiologically inspired three-tank model of human bioenergetics to describe and optimize fatigue and recovery during exercise. The aerobic, phosphagen, and glycogen systems are modeled as coupled reservoirs whose states constrain instantaneous power output. Building on this representation, dynamic programming is used to compute pacing strategies that respect physiological limits while maximizing task-specific goals such as peak power or total work over a fixed duration, enabling individualized, goal-driven exercise prescriptions. The three-tank dynamics are formulated in continuous time and then discretized under a zero-order-hold assumption for simulation and optimal control. Model parameters are linked to standard field …

This article demonstrates the reception of Thomas of Ireland’s Manipulus florum (1306) and John of Wales’ Communiloquium (ca. 1270) in a sermon by King Robert of Naples (1276-1343) promoting the revival of the military alliance known as the Lombard League, and also his use of the Manipulus in another sermon. A full edition of Robert’s sermon “pro liga Lombardie” is appended. It also corrects the misattribution to Robert of a collection of anecdotes and quotations attributed to ancient philosophers and provides a brief comparative analysis of the short and long recensions of the Communiloquium.

“Starlight Suite”: A Compositional Exploration Of The Argo Navis Constellations In Three Movements, Adam Miller

Student Publications

This thesis explores a compositional technique in which stellar constellations are arranged upon musical staves in a variety of iterations to create a basis from which to draw melodic, harmonic, and rhythmic material. These raw extrapolations of unaltered notes are then arranged and orchestrated into thematic music for full orchestra, centered around elements from the mythological background behind the constellations used. An accompanying analysis explains the specific applications of this technique within each movement of the work, the significance of each, and the variety of ways in which musical inspiration was drawn from the raw materials. The objective of this …

Journal of the Association for Communication Administration

This essay explores the conceptual, practical, and relational foundations of building and sustaining communication research labs. Drawing on early models of research teams, we argue that contemporary labs function as living systems that integrate research, teaching, mentorship, and community engagement. The essay outlines practical considerations for creating and maintaining labs, including recruitment, infrastructure, leadership succession, and digital presence, while emphasizing the importance of flexibility and autonomy. Rather than viewing labs as static organizational units, we position them as relational ecosystems that evolve through connection, shared purpose, and adaptability across time and institutions. Ultimately, this work encourages scholars to view lab-building …

Making The Invisible Visible: Cultivating Contexts For Equitable Workloads, Andrea Carlile

Journal of the Association for Communication Administration

Women make up the majority of degree earners and most of those teaching at higher education institutions. Yet, women are not advancing to the highest ranks. How female faculty receive credit for their work may account for the discrepancy in women advancing to the highest ranks. This single-institution case study explored institutional practices and policies as they related to workload satisfaction and rewards for female faculty. Following the framework from the Faculty Workload and Rewards Project, FWRP, the case used the constructs of equity-minded faculty workloads to shape the analysis. Three themes emerged in the analysis: context matters, transparency practices, …

Combining the best available research evidence, the perspectives of patients and communities, and the voices of healthcare workers in guiding policy and practice is essential. All of us involved in providing and strengthening family medicine and primary care need to be good consumers (users) of research, and some will be good producers (doers) of research. In both using and doing research, a helpful starting point is evidence synthesis – a form of secondary research that collates primary research on the same research question. This short …

Dielectric Properties Of Surface-Doped Partially Stabilised Zirconia With Ceramic Nanomaterials, Lara Al-Hakeem, Shihab Zaidan, Wafaa Khalef

Journal of Applied Sciences and Nanotechnology

The microstructural and dielectric properties of Yttria-partially stabilized zirconia (Y-PSZ) were studied before and after sintering with BaTiO3 and WO3 doping. After sintering, FE-SEM analysis revealed increased grain coalescence and growth, with BaTiO3 causing 300 nm grain expansion and WO3 promoting uniform grain distribution without significant grain size increase (~200 nm). These microstructural changes dramatically altered dielectric behavior. All sintered samples had higher dielectric constants than pre-sintered ones between 100–1000 kHz due to reduced porosity and enhanced homogeneity. Dielectric constant was highest in BaTiO3-doped Y-PSZ at lower frequencies, while WO-doped showed superior frequency stability and lower dielectric loss across the …

Impacts Of Nutrient Addition And Disturbance On Coastal Dune Arthropod Communities And Trophic Interactions, Kayla Beitzel

Graduate Theses and Dissertations (2019 - present)

Coastal dune ecosystems face ongoing threats from human-mediated disturbance and altered resource availability. Because these dunes provide critical habitat for many organisms, including shorebirds, beach mice, and arthropods, changes in disturbance regimes or resource availability can impact plant communities and higher trophic levels by altering plant richness and productivity, which in turn influence arthropod abundance and diversity. To examine how disturbance and nutrient addition affect arthropod communities, we established twenty 5×5 m plots on Dauphin Island, crossing mechanical disturbance with a 10 g m⁻² addition of nitrogen, phosphorus, and potassium, replicated across five experimental blocks. Arthropods were sampled using three …

Climate Science And Natural Resource Litigation, Jessica A. Wentz

Sabin Center for Climate Change Law

Climate change has major implications for sustainable use and conservation of natural resources. Many natural systems are already under severe stress and may be unable to sustain historical use patterns; resource management decisions can also exacerbate or mitigate climate change by affecting the balance of greenhouse gases in the atmosphere. This Article describes the legal and scientific basis for recognizing agencies’ obligations to assess and respond to climate change, drawing insights from a survey of U.S. litigation involving forests, fisheries, rangelands, and freshwater resources. The cases suggest litigants have been somewhat successful in driving more rigorous assessments of climate change. …

The Disaster Management Complex: Law’S Adaptations In Times Of Climate Disaster, Michael Burger, Jeffrey Schlegelmilch, Lucia Bragg

Sabin Center for Climate Change Law

The Anthropocene is marked by constant climate-related disasters and defined by the urgent need to foster and implement adaptations to future climate impacts that reduce disaster risk. The intensity, frequency, and severity of extreme weather events continue to rise even as nations and corporations alike miss their emissions targets, all promising a hotter, wetter, and more extreme future. A number of federal agencies, including the Federal Emergency Management Agency (FEMA), have, at times, sought to adapt their own famously fragmented responses to these changing circumstances. However, federal disaster response is conducted against a backdrop of authorizing legislation that is designed …

Flower Color Variation And Its Maintenance: Experimental Ecology Of Serpentine-Adapted Leptosiphon Parviflorus Benth. (Polemoniaceae), Magdalene S. Lo

Master's Theses

Environmental heterogeneity can impose fluctuating selection pressures on species across space and time. If variations of a trait provide fitness benefits in certain environmental conditions but not others, these fitness tradeoffs under fluctuating selection could be a means of maintaining intraspecific variation. A common type of intraspecific variation is the production of anthocyanins, pigments responsible for red, pink, and blue colors in plants and that can also provide protection from abiotic stressors, such as water limitation and heavy metals. Leptosiphon parviflorus Benth. (Polemoniaceae, variable linanthus) is an annual wildflower whose individuals produce either pink or white flowers, and both flower …

An Analysis Of Neuroidal Memory Formation Within D. Melanogaster, Jerry Chang

Master's Theses

The Neuroidal model poses a neurobiologically plausible theory for modeling the brain. This symbolic network has been shown to capture realistic memorization behaviors using the JOIN algorithm. The model has also been recently improved by incorporating Watts-Strogatz small-worlds within its base structure. From the efforts of neuroscience researchers, we have access to the Drosophila melanogaster (D. melanogaster) fruit fly’s connectome, which has been found to also contain small-worlds in this thesis. By synthesizing the Ocellar Ganglion (OCG) region of Drosophila, we compare a digitized version of a real-world brain with an instance of the Neuroidal model. In this thesis, we …

Disease remains one of the major constraints to the productivity and economic success of the California strawberry industry. The most important soilborne pathogen is Macrophomina phaseolina, causing Macrophomina root rot (MRR). The most economically significant airborne pathogens include Botrytis cinerea, causing Botrytis fruit rot (BFR), and Podosphaera aphanis, causing powdery mildew (PM).

Disease severity of MRR is highly dependent on environmental factors. Therefore, understanding which abiotic stressors contribute most to disease development is crucial for effective management. A two-year field experiment at Cal Poly, SLO (2024 and 2025) evaluated the effects of drought stress, two elevated chloride …

Using Scenario-Based Design Activities To Explore Sociotechnical Thinking In Engineering Professionals, James M. Whealan

Master's Theses

Sociotechnical thinking is the ability to recognize the interconnectedness of both technical and non-technical dimensions such as environmental, economic, social, cultural, and political factors. Although traditional engineering curriculum often emphasizes technical knowledge and skills, research suggests that engineering work is inherently sociotechnical. While sociotechnical thinking is a critical engineering skill, relatively little is understood about the nature of it or the different aspects comprised within it. To that end, this study addresses the following research question: What sociotechnical factors do engineering professionals consider in a collaborative scenario-based design activity? To answer this question, we conducted a qualitative study of engineering …
