Analytical And Semi-Analytical Modeling Of Solar Cells Using The Lambert W Function: A Comprehensive Review Of Equivalent Circuits, Adel El-Shahat, Martin Ćalasan, Snežana Vujoševic, Shady H. E. Abdel Aleem

Engineering Technology Faculty Publications

The modeling of photovoltaic (PV) cells through equivalent circuits forms a central element in the analysis, simulation, and optimization of solar energy systems. Traditional approaches often depend on iterative numerical methods to solve the implicit current–voltage (I–V) equations. In contrast, the Lambert W function has emerged as an effective mathematical tool that enables closed-form or semi-analytical expressions for a wide range of PV models. This paper presents a Lambert W-centered review of analytical and semi-analytical formulations for PV equivalent-circuit models, covering classical single-diode and multi-diode structures and modern variants incorporating additional elements, voltage-dependent parameters, and topology rearrangements. The models are …

Interpretable Machine Learning For Bridge-Pier Scour Prediction And Flood Resilience, Adil Khan, Dalya Ismael

Engineering Technology Faculty Publications

Bridge-pier scour is a leading cause of flood-induced bridge failure, yet practice still lacks transparent, physics-informed tools that link data-driven prediction with design guidance. This study develops an interpretable, physics-aware machine-learning framework to predict equilibrium scour depth and translate those predictions into actionable strategies for flood-resilient infrastructure. Using the 2014 U.S. Geological Survey Pier-Scour Database (569 laboratory cases), five models: Gradient Boosting, AdaBoost (Tree), XGBoost, Gaussian Process (RBF kernel), and Kernel Ridge (polynomial), were trained and evaluated with K-fold cross-validation. Model performance was evaluated using R², RMSE, and MAE. Gradient Boosting performed best, achieving training and testing R² of 0.99 …

The Global Onboard Training Programme (Gobt) : A Comprehensive Review, World Maritime University

Reports

A stable supply of qualified seafarers is a critical component of the global maritime logistics industry, which relies heavily on maritime transportation. According to the 2021 BIMCO Manpower Report, an additional 89,510 officers will be needed by 2026. In 2021 alone, there was already a deficit of 26,240 STCW-certified officers, clearly indicating that demand continues to outpace supply. The report also noted a 45.8% increase in the number of female seafarers since 2015, although they still represent only a small share of the overall workforce. Maritime Education and Training (MET) institutions around the world continue to provide training to develop …

Rules Of The Road: Toward National Regulation Of Autonomous Vehicles, Adam Raviv

Journal of Law and Mobility

After decades of promise, self-driving cars are now becoming a meaningful reality on our roads. Yet not a single federal law or regulation governs autonomous vehicle operation in the United States—despite widespread agreement among policymakers, advocates, and industry stakeholders that a national safety framework is necessary. This article provides the first comprehensive legal analysis of what a federal safety regulation for autonomous vehicles can and should look like. It describes the current landscape of autonomous technology. It analyzes both the existing federal legal regime for vehicle safety regulation as well as state, local, and international standards that apply to autonomous …

The following research question was utilized to guide this paper: How do Housing First principals and interventions impact housing stability …

Who Gets To Stay? Selective Compliance, Local Power, And The Politics In San Juan Capistrano, Daniel Fernández

CMC Senior Theses

This thesis examines how California cities can satisfy state housing mandates while systematically under producing affordable housing. Using San Juan Capistrano as a case study, it documents a pattern of selective compliance. That is, a formal planning obligations are met while local governance tools, place-based identity, and discretionary processes that consistently filter housing outcome towards market-rate development and away from lower-income production. The findings suggest that closing California's affordability gap requires enforcement tools capable of reaching beyond formal planning compliance to address the governance mechanisms that shape what actually gets built.

The Economics Of The U.S. Student Loan Market And The Case For The Education Development Financial Institution, Ian Akers

CMC Senior Theses

The United States student loan market is shaped by a variety of market failures–credit constraints, positive externalities, behavioral frictions including myopia, debt aversion, and misperception–that together justify government intervention in the market. Yet the design of federal intervention is just as important as its existence. This thesis details the economic theory underpinning the market for student loans, evaluates three historical federal student loan programs (the Perkins Loan Program, the Federal Family Education Loan Program, and the Federal Direct Loan Program) through the lens of that theory. The thesis then proposes a novel institutional model as a targeted response to the …

Revenge Of The Interceptors? The Dod, Congress, And The Return Of Space-Based Missile Defense During Trump 45, Chad Mcelroy

CMC Senior Theses

The initiation of the Golden Dome for America program has brought space-based missile defense (SBMD) to the forefront of American national security policy and rekindled debates that had laid dormant since the administration of President Ronald Reagan. How, forty-two years after President Reagan first proposed the Strategic Defense Initiative, did SBMD return as a national priority? In lieu of public information about the ongoing Golden Dome initiative, this thesis explores the first Trump administration, otherwise known as Trump 45, in order to analyze the development of SBMD proposals by its proponents in Congress and the Department of Defense. I used …

Revisionist Political Coalitions, Queering, And The Transmission Of Violence, Tom Y. Inouye

CMC Senior Theses

This thesis examines the ways in which violent non-state actors (VNSAs), specifically revisionist political coalitions (RPCs), emerge from a state-centric international system that denies them access to formal avenues of political advocacy, legitimacy, and recognition. Challenging dominant portraits in international security that cast non-state-perpetrated violence as irrational or deviant, I argue that RPCs turn to brutality as a strategic response to exclusion produced by the Westphalian paradigm. Queer theory, particularly the concepts of legibility and strategic disidentification, is central to the reconceptualization of RPCs as “queered” political objects whose existence falls outside the normative boundaries of sovereignty and legitimacy.

No Coup, No Conscience: Coup-Proofing In The Armenian Genocide, Rachel Svoyskiy

CMC Senior Theses

The Armenian Genocide functioned as a form of coup-proofing under the Committee of Union and Progress (CUP). Existing scholarship emphasizes nationalism, wartime radicalization, and security dilemmas, but does not fully account for why the military complied, why dissenters were removed, or how Armenian property became tied to political loyalty. Applying Hicham Bou Nassif’s framework of coup-proofing, this study examines four tactics the CUP used to secure military obedience while carrying out mass violence. First, the regime framed Armenians as an existential threat to align the officer corps ideologically with the state. Second, it promoted the material interests of military and …

Lessons Unlearned: Cultural Competence And The Limits Of U.S. Army Doctrine In Iraq And Afghanistan, Kylie W. Ha

CMC Senior Theses

This thesis examines how the absence of comprehensive cultural and linguistic competence within U.S. Army doctrine contributed to operational and ethical failures during the wars in Iraq (2003–2011) and Afghanistan (2001–2021). It focuses on the gap between doctrinal recognition of culture and language and the failure to institutionalize these elements as measurable, force-wide competencies. The thesis analyzes doctrinal publications spanning the period from 2001 to 2014 and finds that, while these publications increasingly acknowledged the importance of cultural awareness, language, and local context—particularly in counterinsurgency operations—these elements were not embedded as standardized requirements across training, planning, or evaluation. Iraq and …

Allocating Electricity, Alexandra Klass, Dave Owen

Articles

The U.S. electricity system is premised on the ideas that utilities have a duty to serve all customers in their service territories and that electricity supply should always meet demand. Until recently, there has been little reason to question these foundational premises. U.S. electricity demand has remained flat for over a decade, and during earlier periods of growth, new energy generation plants were relatively easy to build. Now, however, electricity experts predict massive load growth—most notably from data centers to power artificial intelligence and cryptocurrency—and building new power plants is no longer easy.

Major efforts are underway to increase electricity …

Ecological Feedbacks In The Earth System, Eugene J. Murphy, Jessica J. Williams, Isla H. Myers-Smith, Vivienne P. Groner, David M. P. Jacoby, Lester Kwiatkowski, Jess Melbourne-Thomas, Emma Ransome, Cristina Banks-Leite, Laurent Bopp, Marion Gehlen, Eileen E. Hofmann, Babette Hoogakker, Nadine M. Johnston, Yadvinder Malhi, Emma L. Cavan

CCPO Publications

Ecological feedbacks are fundamental features of the Earth system, affecting physical processes and chemical cycles. Our understanding of the interactions underlying these feedbacks at different spatial and temporal scales and the extent to which feedbacks affect Earth system functioning remains limited. Climate change and other anthropogenic pressures are already negatively affecting ecological processes in marine, freshwater, and terrestrial ecosystems. These will most likely be amplified in the coming decades under our current warming and socioeconomic pathways. The knock-on impacts on ecological feedbacks have the potential to cause rapid perturbations to the Earth system, and may significantly impact the structure and …

A Computational Approach To Graduated Centrifuge Profiles For Partial Gravity Planetary Environments, Cabell W. Jones

Mechanical & Aerospace Engineering Faculty Publications

Missions such as NASA’s Artemis and SpaceX’s Starship aspire towards creating permanent settlements beyond Earth. In order to achieve this goal, it must be considered that the gravity present on planetary surfaces such as the Moon (0.165 g) and Mars (0.378 g) may be insufficient to support human physiology for long term habitation. On near-Earth missions, issues such as muscular atrophy, neuro-ocular changes, cardiopulmonary variations, and bone mineral density loss have been observed proportional to the duration spent in microgravity. Further studies have suggested that the severity of these conditions scales linearly with decreasing gravity, meaning that astronaut health can …

Rethinking Dfw In Gateway Mathematics: Preserved, Disrupted, And Dissipated Momentum Pathways To Student Retention, John Alan Nunnery, Charles Mathies

Educational Leadership & Workforce Development Faculty Publications

This study examines how disaggregated first-year mathematics outcomes, including failure, low-passing grades, course withdrawal, and no attempt at a credit-bearing mathematics course, are associated with second-year retention at a large, diverse, urban public university. The study extends academic momentum theory by positing and operationalizing preserved (marginal passing), disrupted (failure or withdrawal), and dissipated (non-enrollment) as qualitatively distinct momentum states rather than a single condition. Using a segmented binary logistic regression model with more than 26,000 first-time, full-time students across ten entry cohorts (2012–2021), we estimate differences in retention by mathematics outcome, course type, and cohort context. Results show a pronounced …

Simulating Social Attitudes With Llms: Accuracy, Demographic Effects, And Refusal Behavior In The Sensitive Domain Of Suicide Prevention, Cristina J. Perez, Michael P. Vasquez Jr., Philippe J. Giabbanelli, Patrick Y. Wu

VMASC Publications

Large language models (LLMs) are increasingly used to simulate public opinion, yet their validity in sensitive policy domains remains underexplored. We evaluate whether LLMs can reproduce attitudes toward suicide prevention policies using 32 questions drawn from seven nationally representative U.S. surveys (2023-2025). We systematically vary demographic conditioning (race/ethnicity, gender, age, education, income, party), prompt framing (direct elicitation, respondent embodiment, specialist embodiment), and model architecture (GPT-5 Nano, DeepSeek V3.2, Meta Llama 3.1 8B, Mistral Small 24B). Across 811,560 prompts, the mean absolute error—the average gap between predicted and human response distributions—is 23 percentage points. We also find that LLM responses to …

Geography Of Erasure: Manufactured Housing, Heat Exposure, And State Neglect In Florida, Gianna M. Hutton

Pomona Senior Theses

This thesis examines Florida's manufactured housing communities through the intersecting frameworks of energy justice, critical heat studies, and housing displacement scholarship, centering how structural, political, and economic forces shape uneven exposure to thermal insecurity and housing precarity. Using a mixed-methods approach combining statistical regression analysis of American Community Survey microdata (2019-2023) and spatial case study of Miami-Dade County's heat governance and The Li'l Abner Mobile Home Community’s displacement, this research investigates how manufactured housing residents experience compounded exclusions across energy systems, urban heat governance, and housing security. The findings reveal that manufactured home residents face a 26% higher energy burden …

Left In The (Road) Dust: Analyzing Advanced Clean Cars Ii In California’S Disadvantaged Communities, Jj Hoffman

Pomona Senior Theses

Across the United States, air pollution disproportionately impacts minority groups. California’s Advanced Clean Cars II (ACC II) waiver was positioned to lead to significant environmental justice impacts, such as reductions in emissions and adverse health outcomes, by establishing stricter regulations for vehicle emissions and ensuring that 100 percent of new passenger vehicle sales are zero-emission by 2035. As the federal government recently nullified ACC II, pollution, and by extension health, could worsen, especially in disadvantaged communities. The thesis established several important relationships, including how disadvantaged communities experienced higher traffic, pollution, and worse health outcomes than non-disadvantaged communities. Though the results …

Sex, body mass index (BMI), and body fat % (BF% via circumference and an equation) were measured. Accelerometer PA and sedentary time were computed for IPAQ categories …

Legislative Debate-Attributed Suicidality Among Lgbtq+ Adults: The Buffering Effect Of Community Belongingness, Keith J. Watts, Shawndaya S. Thrasher, Laneshia R. Conner, Nicole Campbell, Louis G. Baser, Dekeitra Griffin, Sydney P. Howard, Missy Spears, Justin X. Moore

Counseling & Human Services Faculty Publications

Background: In recent years, the sociopolitical landscape in the United States has shifted due to an increase in state-level legislation regarding LGBTQ+ rights, a trend that has been particularly pronounced in the Commonwealth of Kentucky. While the mental health impacts of enacted laws are increasingly documented, a critical gap remains in understanding the psychological toll of the legislative debates themselves—the prolonged periods of public discourse surrounding the restriction of rights. Methods: Utilizing data from the 2025 Queer Kentucky Survey (N = 817), this exploratory study examined the association between LGBTQ+ community belongingness and acute suicidality attributed specifically to anti-LGBTQ+ legislative …

Social Safety And Social Security: Validating Context-Specific Instruments For Slums, Liss D. Romero, Katherine Palacio, Zacheous Ako Abang, Valeria Silgado, Humberto Llinas, Leidy González, Erika Frydenlund, Daniel Bolivar, Jose J. Padilla

VMASC Publications

Social safety and social security are concepts that help explain a community's well-being by assessing how it manages and mitigate existing, or perceived, risks. However, these terms are often conflated, which can limit understanding, particularly in areas with unstable living conditions. This study explores both concepts in the context of residents living in slums. As the number of displaced people grows, slums and informal settlements are becoming increasingly common worldwide, making it essential to clarify these concepts. Residents of slums face numerous hazards, including crime, violence, inadequate housing, overcrowding, and limited access to essential services. To measure social safety and …

Assessing The Feasibility Of Small Modular Reactor Deployment On Islands In Southeast Asia And The Pacific, Hayden C. Beauchemin

CMC Senior Theses

This study looks at the feasibility of using Small Modular Reactors (SMRs) to provide island microgrids in Southeast Asia and the Pacific with clean, reliable electricity. SMRs are compared to current methods of electricity generation, namely diesel generators, as well as to renewable alternatives. Policymakers will face geopolitical, technical, economic, and domestic political challenges to SMR deployment. The key considerations of SMRs, including economic viability, safety approaches, public attitudes, and diplomatic relations are considered, and solutions are identified for issues such as financing and nuclear waste disposal. The analysis reinforces the conclusion that SMR deployment is feasible for islands in …

Understanding The Flow: Deconstructing The Link Between Immigrants And Fentanyl, Madeline F. Nesbitt

CMC Senior Theses

This thesis explains how a false link between undocumented immigration and fentanyl becomes widely accepted in the United States. Empirical data show that most fentanyl enters through legal ports of entry and that U.S. citizens account for the majority of those caught transporting it. Why, then, do 41% of Americans attribute overdose deaths to migrants trafficking fentanyl? This project examines how this myth is built, repeated, and sustained, and what policy consequences follow from it.

When complex social problems lack clear culprits, political actors often manufacture them through scapegoating. Current literature documents how political actors link immigrants to drug crimes, …

Rethinking Reentry In The United States: A Comparative Analysis Of Incarceration Strategies In Norway, Singapore, And Austria, Amelia Ulmer

CMC Senior Theses

The prison reentry system in the United States remains a pressing social, economic, and political issue, as hundreds of thousands of prisoners are released each year with few resources to assist them with their transition. In fact, these previously incarcerated people are arguably set up to fail, which leads to over half of them reoffending within two years. This thesis analyzes how the United States should reform its current prison system based on lessons learned from three international case studies. These three case studies, Norway, Singapore, and Austria were chosen as countries that have globally low recidivism rates and unique …

From Statute To Classroom: The Implementation Gap In California's Queer-Relevant Sex Education Policy, Alejandro Quiroz-Novela

CMC Senior Theses

This thesis examines why strong sex education laws do not reliably translate into consistent classroom experiences for LGBTQ+ students. Using a qualitative single-case study of California, it traces the evolution from SB 71 (2003) to the California Healthy Youth Act (CHYA) (2016) and analyzes how mandates move through a decentralized governance chain. Drawing on statutes, legislative records, state guidance, curriculum review tools, advocacy reports, media accounts, and public indicators, the study focuses on implementation mechanisms rather than estimating causal health effects. Three findings emerge: CHYA sets a clear legal floor but is difficult to verify at scale; district discretion and …

The Future Of U.S. Higher Education: Equity Implications Of Shifting Immigration Policies, Research Institute For Social Equity Rise

Research Institute for Social Equity

This report examines the impact of U.S. immigration policies on higher education and international students from 2000 to 2025. It traces five major policy eras, from the post- 9/11 security overhaul and Obama-era expansion to the restrictive turns of 2017–2020 and 2025, and analyzes how shifting regulations have influenced enrollment patterns, economic contributions, and student well-being. Despite hosting more than 1.1 million international students in 2023–2024, the U.S. share of the global student market has fallen from 20% to 16%, underscoring how policy volatility and restrictive measures weaken national competitiveness. Drawing on federal data, scholarly research, and institutional reports, this …
