Adaptation Of A Seismic Outreach Program: Collaboration Between University Students And Seaoc Mos, Paul Quinter, Ryan Lovejoy, Kristin Potterton, Anahid A. Behrouzi, Lelli Van Den Einde

Architectural Engineering

For nearly two decades, students in University of California, San Diego’s Society of Civil and Structural Engineers (UCSD SCSE) chapter have conducted a Seismic Outreach program that reaches around a thousand 4th and 6th grade students annually. This success motivated an effort to share and deploy the curriculum through other universities. To achieve this, the Structural Engineers Association of San Diego (SEAOSD) sought and received a 2024 National Council of Structural Engineers Associations (NCSEA) grant that supported collaboration between UCSD SCSE, the Structural Engineers Association of Southern California (SEAOSC), and California Polytechnic State University, San Luis Obispo (Cal Poly). This …

Navigating The Pathway To Become A Structural Engineering Practitioner-Educator, Kristin Potterton, Anahid A. Behrouzi

Architectural Engineering

Many structural engineers attribute their exposure as students to industry mentors as critical to their recruitment into the profession and the initial development of problem-solving skills they now use in the workplace. The desire to provide similar opportunities to the next generation often motivates practitioners to engage in K-12 outreach or take on university positions to teach courses and advise projects. However, as a young engineer the route to becoming a practitioner-educator is not always clear without an advisor who has sought a similar path that can guide them. To address this, the paper will summarize survey results from practicing …

Baseline Nutrition Knowledge And Feasibility Of A Whatsapp-Delivered Nutrition Education Intervention Among California Wildland-Urban Interface Firefighters, Lauren E. Anderson

Master's Theses

Wildland firefighters perform physically demanding work under challenging environmental conditions that place substantial demands on nutritional health and occupational performance. Despite the importance of nutrition in supporting physical performance, recovery, and long-term health, limited research has examined nutrition knowledge and dietary behaviors among California wildland firefighters or evaluated the feasibility of remotely delivered nutrition education interventions within this occupational population. Therefore, the purpose of this pilot study was to assess baseline nutrition knowledge, nutrition self-efficacy, and dietary behaviors while evaluating the feasibility of a 12-week WhatsApp-delivered nutrition education intervention among California wildland firefighters.

Twenty-four firefighters completed the baseline assessment and …

Hyperchaotic Noise Generation For Adversarial Encryption In Privacy-Preserving Image Classification, Neeraja Beesetti

Master's Theses

Artificial intelligence systems make useful predictions by taking in data and returning a classification, recommendation, or decision. Obtaining that prediction, however, requires sharing the data first. This creates a fundamental privacy challenge in machine learning: users must expose their data to receive a valuable prediction. Machine learning systems increasingly rely on cloud-based image classification for this reason, transmitting images from edge devices to remote servers rather than running large models locally. This creates a conflict between the accuracy a classifier requires and the privacy a data owner wants. Traditional encryption destroys the image structure on which a classifier depends, while …

Evaluation Of General Voronoi Diagram Decomposition For Harmonic Fields In Navigation Of Dynamic Environments, Franco Abullarade

Master's Theses

Harmonic potential fields provide provably minimum-free navigation, but any change to the workspace geometry invalidates the field and forces a costly global recomputation, typically restricting them to static environments. This thesis extends the harmonic map framework of Vlantis et al., which maps the free workspace onto a unit disk and uses an atlas of per-region transformations, to dynamic indoor settings. First, we replace their manually annotated room partition with an automatic decomposition based on the Generalized Voronoi Diagram, allowing the atlas to be built from an arbitrary occupancy grid in an automated way. Second, we introduce a localized repair procedure …

Multidimensional Determinants Of Gait, Balance, And Softball Performance In Female Youth: Biomechanics, Resource Access, And Psychosocial Factors, Allie G. Mcauliffe

Master's Theses

Movement quality is a fundamental indicator of healthy childhood development and supports physical, emotional, psychosocial, and cognitive well-being. Movement quality is influenced by multiple biomechanical, environmental, and psychosocial factors, yet the relationships among them remain poorly understood in underrepresented populations such as female youth, particularly in softball. Previous studies have largely examined biomechanics, resource access, and psychosocial experience independently, and few have investigated how these factors interact in female youth softball players. To address this gap, this study compared gait and balance characteristics between softball (N = 34) and non-softball (N = 7) female youth, examined associations between resource access, …

Developing A Rapid Urban Forest Assessment System For Sustainable City Greenification, Daniel Gonzalez

Master's Theses

This thesis presents the Rapid Urban Forest Assessment (RUFA) system, a web-based platform that integrates urban tree inventories and aerial tree detection to assess forest health across California’s census-designated places. RUFA combines inventoried tree records with coordinates detected from high-resolution multispectral imagery using convolutional neural networks, then computes a composite RUFA Score from four metrics: canopy cover percentage, trees per capita, tree diversity (TD-50), and tree evenness. The thesis addresses two engineering challenges in building the dashboard: querying and aggregating over seven million tree records in real time, and rendering spatial summaries at multiple zoom levels without recomputing cluster assignments …

Beyond Beliefs: Factors That Shape Agricultural Plastic End-Of-Life Management Among California Strawberry Growers, Kyle Y. Cahitas

Master's Theses

The practice of using plastics in agriculture is so prevalent it has earned its own name: plasticulture. One key plasticulture tool is polyethylene (PE) mulch film, a thin plastic sheet laid over the field for a single growing season and pulled out before the next. Because PE film is hard to recycle, most of it ends up in a landfill, yet how growers decide what happens to used plastic mulch has rarely been studied. To identify what shapes that decision, this study draws on a survey of California strawberry growers (n = 126). Twenty variables, spanning grower attitudes, farm characteristics, …

Synthesis And Characterization Of Carbon Quantum Dots And Gold Nanoparticles For Norovirus Biosensing Applications In Water Systems, Breanne Evans

Master's Theses

Rapid, reliable detection of viral pathogens remains a significant challenge across water-treatment and environmental monitoring systems, including drinking-water, wastewater, water reuse, and environmental surveillance applications. Waterborne viral contamination can pose substantial public-health risks, making early detection essential for protecting water quality and responding quickly to treatment failures or contamination events. Direct potable reuse (DPR) is one particularly demanding example because it requires continuous verification of treatment performance and the broader need for rapid virus monitoring extends across many water-treatment and environmental surveillance applications. Norovirus is a priority target because of its widespread occurrence in wastewater, environmental persistence, and exceptionally low …

Constructing Executive Presence Within The Double Bind: Women’S Experiences Of Leadership Communication, Sydney Anne Shumaker

Communication Studies

Women in executive leadership often face a gendered double bind, expected to be warm and approachable, while also appearing competent and confident. This qualitative study examines how women executives develop executive presence and navigate these workplace expectations. Drawing on Warmth-Competence Theory and Impression Management Theory, the study explores how women leaders adapt their communication, manage self-presentation, and balance perceptions of warmth and competence in professional settings. This study involved conducting semi-structured interviews with four women in corporate executive-level roles. Thematic analysis of participant responses revealed five key themes: adaptive communication, varied experiences with gendered workplace expectations, the importance of credibility …

Presence Without Exposure: Feminist Pedagogy In The Home-As-Classroom, Kristy Kelly

Feminist Pedagogy

This commentary reflects on teaching during and after COVID-era remote instruction, when the classroom moved into students’ homes and “presence” became equated with visibility. Drawing from a course-based study conducted with students, I describe how patterned differences in men’s and women’s experiences of online participation illuminated the unequal costs of being seen—costs shaped by privacy, domestic constraints, and the risks of interpretation. I argue that feminist pedagogy requires decoupling engagement from visual exposure and designing participation around those most vulnerable to surveillance and stigma in online spaces. The essay outlines practical shifts—camera-optional norms, modality-equivalent participation, structured breaks, and low-stakes entry …

Xenaform Algorithm, Alden Ulysses Quandt

Architectural Engineering

This project develops a computer-generated form-finding process for XenaForms, a discrete folded-plate shell system made from rigid triangular panels and hinge-like edge connections. Using Blender and Python, the workflow generates an initial top-down triangular strip, expands it into a fuller shell through stability-guided growth, checks the resulting geometry against a local stability rule, and culls unstable or erroneous elements. The algorithm translates XenaForm stability principles into a usable design tool while also accounting for constructability through sheet-size constraints and geometric collision checks. The result is a Blender-based workflow that can rapidly produce stable, varied XenaForm models for architectural, sculptural, and …

The Regulatory Costs Of Wine Production In Napa County, Lynn Hamilton, Michael Mccullough

Agribusiness

Unlike other food products, commercial alcoholic beverage production has been subject to federal regulation and taxation since the founding of the United States, with specific wine taxes being levied during the wartime Emergency Revenue Act of 1914 (Cilluffo and Gravelle, 2024). Since then, taxation and regulations have expanded, with many new laws originating at the state level. Additional regulatory costs, combined with the current decline in consumer demand raise questions regarding the long-term viability of California wine production. Napa County Farm Bureau contacted Cal Poly to assess baseline conditions in the industry by conducting a case study of regulations accruing …
