Determining K Clusters In K-Means Clustering With The Crab Algorithm, Jasmine Kristine S. Cabrera

Master's Theses

Unsupervised clustering often faces the challenge of determining the correct number of clusters in the absence of a true target variable. Traditional methods such as the Elbow Method and the Silhouette Score can produce ambiguous results and rely on assumptions about cluster shape or separation. To address this, we created the Clustering Rivals and Buddies (CRAB) algorithm which evaluates clusters based on stability across multiple subsamples. CRAB uses pairwise classifications to identify points that consistently group together called “Buddies” and points that remain separated called “Rivals.” Applied with K-means, CRAB accurately recovers underlying cluster structures in both spherical and non-spherical …

Teaching Multi-Core Architecture: Design And Implementation Of A Cache-Coherent Cpu For Undergraduate Education, Isaac R. Lake

Master's Theses

Modern computing has relied on multicore processors for high performance for nearly two decades, yet undergraduate computer engineering curricula often provide limited exposure to parallel hardware architectures and their design challenges. This thesis presents the design of CPE 433, a course that extends the pipelined and cached OTTER CPU developed in CPE 233 and CPE 333 into a multicore processor capable of running parallel workloads. The thesis documents the architectural changes required to adapt the verified single-core design into a multicore system, including MMIO-based interrupt support, a shared cache hierarchy with cache-coherence mechanisms, and clock-gated modules. It further presents a …

Implementation Of A Line-Scan Camera Triangulation Sensor For A Ball Balancer, Jackson R. Mclaughlin

Master's Theses

Ball Balancer or Ball on Plate systems are used for education and research in control theory. These consist of a plate which can be actively tilted, with a ball rolling on the surface. Students are challenged to model the dynamics of the system and implement a control loop which is capable of stabilizing the ball by actuating the plate.  The mechatronics group at Cal Poly is developing hardware for one of these ball-balancer systems, for future use in the Mechanical Engineering curriculum.

The position of the ball relative to the plate must be measured in order to control and stabilize …

Practice-Oriented Seismic Design And Retrofit For Mid-Story Isolated Buildings, Luke Reilly

Master's Theses

This study reviews the state of the art of MSI and evaluates a practical framework for preliminary design using coupling coefficients. A database of 155 research documents is compiled and classified into analytical, mixed numerical, computational, experimental, and miscellaneous studies. The review identifies major research trends, common modeling approaches, important design parameters, and remaining limitations. In addition, 16 representative MSI building projects are reviewed. These applications show that MSI is most often used for retrofit, vertical expansion, mixed-use buildings, over-track construction, and buildings with major functional or structural discontinuities. The study then examines the Coupling Coefficients (CCs) Method as a …

Boundary Influence In Truncated Groundwater Models: Reconstructing A Local-Scale Modflow Model From A Consultant-Developed Regional Model In The Monterey Subbasin, Bruce K. Liscomb

Master's Theses

Regional groundwater models built by consultants contain valuable calibrated frameworks but are often too large and complex for repeated local-scale analysis. Rather than rebuilding an entirely new smaller model, this study truncates the existing consultant-built regional model of the Monterey Subbasin, preserving the original grid structure and parameter framework while reducing the active domain to a manageable size for planning-level use. A key finding is that boundary-condition representation exerted a dominant influence on simulated groundwater behavior within the truncated domain, highlighting that truncation is a structural decision that meaningfully affects how the model responds. Model performance was evaluated two ways. …

There Be A Dragon, Audreanna Elliott

ETDs from 2020-2029

There Be a Dragon is set in a roughly medieval era world named Aleovion. Evren is the protagonist of the story, a young woman freshly seventeen on the cusp of what should be amazing things. She’s in her last year of schooling and will be on her way to escaping the misery her school has brought her, and on top of that, this is the year she should finally ‘manifest’. Evren’s a part of a sect of beings in this world called ‘Embodied’, people whose ancestry is touched by a mystical creature. This allows them to act as conduits for …

The Court Of Small Things, The Curse Of Legal Superstition: The Precipitous Decline Of Small Claims Court, Why It Matters, And What Can Be Done About It, Telia Mary U. Williams

Nevada Law Journal

This Article addresses the precipitous decline of small claims courts in the United States and argues that their erosion is more than administrative; it is a democratic and constitutional crisis. Small claims courts were once the laboratories of everyday justice, where ordinary citizens could access law without lawyers, ritual, or mystery. The seemingly minor disputes of the small claims court illuminate the democratic soul of American law. Yet, over recent decades, filings have declined dramatically, and the locus of power has shifted from the poor to repeat-player institutional actors. This is in part due to what I call, “legal superstition,” …

Resource Assessment Report No. 8: Pilbara Prawn Resource - 2024 Assessment, Inigo Koefoed, Rachel Marks, Scott Evans, Sharon Wilkin, Jason How

Resource Assessment Reports

The Pilbara Prawn Resource (Resource) is accessed by three managed commercial fisheries; the Exmouth Gulf Prawn Managed Fishery (EGPMF), the Onslow Prawn Managed Fishery (OPMF) and the Nickol Bay Prawn Managed Fishery (NBPMF). All three fisheries are managed under effort controls, with the EGPMF and OPMF targeting brown tiger prawns (BTP; Penaeus esculentus), western king prawns (WKP; Penaeus latisulcatus), blue endeavour prawns (BEP; Metapenaeus endeavouri), and lesser quantities of banana prawns (Penaeus merguiensis). The NBPMF primarily targets banana prawns while also catching BTP, WKP, and BEP in lower numbers. These fisheries are situated adjacent to one another along the Pilbara …

Ra Hub: Streamlining Resident Advisor Workflows Through A Mobile App, Samantha Danahe Gonzalez

Graphic Communication

This project explores the need to improve the workflow experience for Residential Advisors (RAs), specifically focusing on polychat logging and event planning workflows that currently rely on multiple disconnected software platforms. This fragmented system creates confusion and makes it difficult to complete responsibilities efficiently and accurately. Survey findings revealed frustrations with tracking tasks, managing workflows, and navigating between systems. In response, this project proposes a centralized workflow system designed to create a more organized, accessible, and userfriendly experience for RAs.

(R2133) Analysis Of A Bulk Queue With Balking, Adaptive Overloading Service, Multiple Vacation, Inspection And Rework, S. Karpagam, R. Lokesh

Applications and Applied Mathematics: An International Journal (AAM)

We consider a queueing system that utilizes a single server to manage product flow through bulk and overload service modes, depending on queue length. Balking occurs when the queue length reaches ‘N’. After completion of service, products undergo quality inspection, with defective products sent for rework based on specific probabilities. If the product is non-defective, the server continues processing until the queue length exceeds a certain threshold; beyond this point, the server is either routed back to bulk service or directed to an overload service. Also, the server goes into a vacation mode when the queue size is below a …

Rethinking Pakistan Studies: The Grounds Of Regional Knowledge After South Asia, Zoya Sameen

FAS Pakistan

This article rethinks Pakistan Studies as both a pedagogical project and a field of knowledge by examining the limits of history as a tool of legitimation. It argues that in the public sphere, history often serves to authorize the present, and shows how Pakistan Studies has historically operated within this framework. At the same time, the article suggests that this condition opens up another possibility: to understand history not as passive inheritance but as an active demand upon the present. Seen in this light, Pakistan Studies emerges not as a stable body of knowledge but as a series of shifting …

Loint: A Framework For Geospatial Data Quality Management Of Integrated Bim-Gis Models To Support Digital Twin Development In Construction And Renovation Applications, Peshawa Mohammed

Doctoral

The development of high-quality digital twins of built assets is essential for resolving defects and integrating off-site fabricated components in construction and renovation applications. A key component of digital twins is the three-dimensional (3D) digital models. Building Information Modelling (BIM) and Geographic Information Science (GIS) models serve as valuable geospatial sources for these models. The integration of BIM and GIS data enables the creation of comprehensive digital twins within a georeferenced national mapping framework. Since digital twins are developed to reflect the existing conditions of the assets in the real world, geospatial surveying instruments and techniques are typically used to …

Human Rights, Between Peace And Dignity, Ryan Liss

Michigan Journal of International Law

Today, it seems self-evident that human rights are enshrined at the international level because they protect universal human dignity—a cosmopolitan entitlement that cannot be left to the contingencies of domestic law. The prevalence of this received wisdom, however, masks a fundamental transformation in the idea of human rights over the last century. When human rights were first enshrined in international law—during and following the Second World War— their international status was not seen to be justified primarily by the inherent dignity of persons, but by the instrumental role human rights were understood to play in securing interstate peace. This article …

Roots And Greens: Discovering The Power Of Indigenous Produce, Abiodun T. Atoloye, Sherif O. Olasoji, Ebunoluwa G. Ibidapo

Nutrition, Dietetics, and Food Sciences Courseware

The curriculum was designed in alignment with the Cognitive Theory of Multimedia Learning (CTML), Empowerment Theory (ET), and Social Cognitive Theory (SCT) frameworks. These frameworks were used to determine the selection and sequencing of learning activities. As reflected in CTML principles, the use of texts, images, infographics, and videos enhances knowledge retention and information comprehension and helps prevent cognitive overload. Through activities, homework, and family engagement, the principles of ET were incorporated into the curriculum to facilitate participants’ perceived control over food-related decisions. Additionally, by applying the principles of SCT, the curriculum incorporates scenario-based questions, opportunities to engage with peers, …

The Fivestar Method: An Interchangeable Intervention For Ptsd Nightmares And Waking Traumatic Events, Gregory Sparrow, Valerie Leija, Mark Thurston

Human Development and School Services Faculty Publications

There is a variety of trauma resolution methods that focus on reducing the emotional impact of nightmares and/or waking traumatic memories. The revision of nightmares through imagery rescripting represents one of the effective evidence-based methods. In contrast, traditional dream analysis represents an unlikely intervention for trauma resolution, given cultural assumptions regarding the presumed fixed or predetermined nature of dreams. The co-creative dream paradigm, in contrast, introduces the notion that the dream ego can intervene to shift the dream’s unfoldment toward resolution, both retroactively by reliving the original dream in a new way, and prospectively by preparing for new responses in …

A Performance-Weighted Environmental Assessment Of Ultra-High-Volume Fly Ash Substitution In Portland Cement Concrete, Youngguk Seo, M.A. Karim, Teddy Tzvetkov, Joshua Hardy

Faculty Articles

Fly ash substitution for cement in Portland cement concrete (PCC) has been regarded as a sustainable solution, but its widespread application remains constrained by concerns over mechanical performance and durability of PCC, especially at higher replacement rates. This study evaluates PCC mixes incorporating fly ash Type C (FA-C) or Type F (FA-F) across cement replacement rates from 10% to 90%, tracking fresh-state workability, compressive strength, and surface electrical resistivity at 7, 14, and 28 curing days. A process-based life cycle assessment (LCA) with the TRACI 2.1 method quantified global warming potential (GWP, kg CO₂/m³) under a …

From Lineage Discovery To Conservation Prioritisation, Zachary G. Macdonald, Joscha Beninde, Julian R. Dupuis, Thomas W. Gillespie, H. Bradley Shaffer, Gregory F. Grether

Entomology Faculty Publications

Accurate inferences of diversification and evolutionary processes depend on knowing how many independently evolving lineages exist within nominally widespread taxa. Uncertainty in lineage number and composition also limits our ability to meaningfully prioritise conservation efforts. Addressing these knowledge gaps requires frameworks that sequentially identify distinct lineages, assess mechanisms that contribute to their divergence, and quantify spatial and environmental determinants of their genomic diversity. With these goals in mind, we apply whole-genome, ecological, and morphological analyses to the American rubyspot damselfly (Hetaerina americana), a widespread and well-studied North American insect that has been long regarded as a single species of least …

Public Perceptions Of Family Caregiving Of Children Versus Older Adults, Elizabeth S. Scott, Tamar Kricheli-Katz

Faculty Scholarship

The population of older adults in the United States is growing at a rapid rate, both because people are living longer lives and because older adults are an increasingly large share of the population as baby boomers age. It is predicted that by 2030, one in ¿ve adults in the United States will be of retirement age, and one in six people worldwide will be age 60 or older. By 2034 there will be more adults age 65 and older in this country than minor children under age 18.

Among the important consequences of this demographic trend will be a …

The Effects Of Carbon-Fiber Plates And Peba-Based Midsole Foam In Running Shoes On Lower-Limb Joint Kinetics And Kinematics In Recreational Female Runners, Jordan M. Allen

Master's Theses

The recent increase in long-distance running participation and the rapid advancement in footwear technology have created a need for research on injury prevention in this growing population of recreational runners. When “super shoes” were first introduced to the running scene, they caught the attention of runners worldwide with the rapid improvement in marathon performance [1]. Today, every major running brand offers its own version of a super shoe, each incorporating a carbon-fiber plate and PEBA-based midsole foam. While previous studies have shown the performance benefits of these shoes, a gap remains in the literature regarding how they impact knee, hip, …

A Blind Eye To Justice: Blind Pleas In The American Courtroom, Meghan Koza, Makayla Nolen, Stuti Kokkalera

Journal of Criminal Justice and Law

Over 90% of criminal court cases are decided through plea negotiations, rather than through a jury or bench trial. Within the broader context of plea negotiations is the use of a “blind” or “open” plea, where defendants consent to the court’s decision without a chance to participate in the bargaining process. In entering blind pleas, defendants must waive constitutional trial rights with the hope that they will be given a more lenient sentence but are largely left in the dark during the process. This study aims to provide a national overview of the utilization of blind pleas in the United …

Developing Sight-Reading Proficiency In Music Education: A Synthesis Of Instructional Strategies And Pedagogical Approaches, Charles Clements Ii

Theses

Sight-reading is a foundational skill in music education that enables students to perform unfamiliar musical material independently. Despite its importance, instruction is often inconsistent and driven by performance priorities rather than systematic skill development. This thesis synthesizes existing research on sight-reading pedagogy to identify effective instructional strategies and organize them into a cohesive framework for educators.

By connecting research to classroom application, this project provides a practical, research-informed model for sight-reading instruction. The findings suggest that effective instruction requires a structured and integrated approach that supports both cognitive processing and musical performance, ultimately promoting greater student independence and musical literacy.

The Implementation Of Scintillation Detectors With The Cuore/Cupid Collaboration In The Search For Neutrinoless Double Beta Decay, Reese Sandra Cormier

Physics

CUORE (Cryogenic Underground Observatory for Rare Events) is an experiment at the Gran Sasso National Laboratory in Assergi, Italy, currently searching for an answer to the matter-antimatter asymmetry problem; the question: why do we exist? One proposed explanation is neutrinoless double beta decay, a theorized exotic decay that would prove that neutrinos are their own antiparticle, violating the current Standard Model for particle physics. However, current detection methods do not distinguish different types of particle interactions, resulting in alpha decays contributing to the background. Therefore, the experimental sensitivity is too limited to make confident determinations about the data. For this …

Hallucinations And Hits: Generative Ai Patent Searching Performance, Pitfalls, And Library Best Practices, Aidan J. Whitlock, Denise A. Wetzel

Journal of the Patent and Trademark Resource Center Association

One of the most challenging aspects for inventors seeking to obtain a patent is conducting an effective preliminary prior art search. The process requires specialized skills and experience to assess the relevant information that many novice inventors do not possess. However, artificial intelligence (AI) tools and Large Language Models (LLMs) offer potential new ways of accessing legal and technical expertise. This study surveys five popular publicly available LLMs ability to aid in conducting a preliminary prior art search. A list of best practices and strategies for using AI tools to conduct preliminary patent searches are outlined at the conclusion of …
