Safe-R2r: A Safety-Aware And Budget-Optimized Retrieval Controller For Rag Systems, Mandar Sunil Gondane

Master's Projects

Retrieval-Augmented Generation (RAG) improves factual grounding in large language models by incorporating external evidence during inference. However, most RAG systems rely on fixed retrieval strategies that ignore query difficulty, computational cost, and prediction uncertainty. This project introduces SAFE-R2R (Safety-Aware and Budget-Optimized Reason-to-Retrieve), a retrieval controller that treats retrieval as a query-dependent decision problem. SAFE-R2R organizes retrieval into a multi-rung ladder ranging from no retrieval to deeper retrieval with reranking. At each rung, the system generates an answer, computes reliability signals, and combines them into a risk score used within a conformal calibration framework to decide whether to accept the answer …

Multi-Agent Path Planning And Optimization Using Q-Learning, Chirag Rudrish

Master's Projects

Robot navigation in a multi-agent setting requires a balance between safety and efficiency, especially in dense environments. In these two-dimensional spaces, the scope for geometric errors is much less and could lead to collisions or immobility. This project proposes to address the navigation task using a two-phase path planning pipeline that combines reinforcement learning and convex optimization in a scalable and robust manner. The first phase consists of generating diverse collision-free paths using a Q-learning agent that is trained on a visibility graph representation of the environment. The discretization of the environment using waypoint-based graphs allows the agent to train …

Cost-Aware Predictive Routing For Vision-Language Models, Sahil Sait Naveed

Master's Projects

Vision-language models (VLMs) are increasingly used for multimodal tasks, but their inference costs vary widely across model tiers. This work presents a predictive routing framework that assigns each query to the most cost-effective VLM by using multimodal embeddings, clustering, and per-cluster model error estimates. Evaluated on six commercial VLMs, the selected router reduces average cost by about 49 percent relative to the quality-first setting on both validation and test. This comes with accuracy losses of 0.4 percentage points on validation and 0.9 on held-out test data. It also outperforms K-NN and ZeroRouter routing baselines while providing lowercost operating points than …

Stepwise Sudoku Reasoning Training Using Transformers, Lok Man Chu

Master's Projects

Sudoku is a constraint satisfaction problem that serves as a testbed for studying reasoning and stepwise deduction. While many solvers can produce correct solutions, they often fail to generate human interpretable sequences of logically consistent steps. This study investigates whether a transformer trained on stepwise deduction traces can learn to solve Sudoku puzzles through sequential, logically deducible moves. Results show that solve accuracy improves significantly with more training data, reaching approximately 78% at 1500k samples. Stepwise analysis indicates that the model effectively learns simple strategies, achieving near-perfect performance. However, performance on more complex strategies remains limited. Overall, while the model …

Adaptive Real-Time Fraud Detection Using Online Learning And Explicit Concept-Drift Detection, Purva Govind Tugaonkar

Master's Projects

Real-time credit card fraud detection faces challenges such as extreme class imbalance, delayed feedback, and concept drift in transaction streams. This project implements and evaluates an adaptive streaming fraud detection framework based on three methodologies: (1) online learning with incremental updates, (2) explicit conceptdrift detection using statistical monitoring, and (3) separate models for immediate and delayed supervision, combined with cost-sensitive learning and anomaly detection. The system processes the credit card fraud dataset in a batched streaming fashion, uses multiple online learners and ensembles. Experiments show that online, driftaware models maintain high recall on frauds while controlling false positives under imbalanced …

Ai Deployment Authorisation: A Global Standard For Machine-Readable Governance Of High-Risk Artificial Intelligence, Daniel Djan Saparning

Student Publications

Modern artificial intelligence (AI) governance lacks a formal, enforceable mechanism for determining whether a given AI system is legally permitted to operate in a specific domain and jurisdiction. Existing approaches-such as model cards, audits, and benchmark evaluations provide descriptive information about model behaviour and training data but do not produce binding deployment decisions with legal or financial force. This paper introduces the AI Deployment Authorisation Score (ADAS). This machine-readable, regulator-grade framework evaluates AI systems across five legally and economically grounded dimensions: Risk, Alignment, Externality, Control, and Auditability, derived from safety engineering, alignment theory, algorithmic accountability, and liability economics. ADAS produces …

Efficient Organic Molecular Crystal Structure Prediction Using The Density Functional Tight-Binding Method, Maureen M. Kitheka, Yan Jing, Yan Yao, Puja Goyal

Faculty Publications – Chemistry

Over the years, computational crystal structure prediction (CSP) for organic molecules has thrived as an area of research, spanning various scientific disciplines and having significant applications in industries such as pharmaceuticals and agrochemicals. Within the field of batteries, redox-active organic materials (ROMs) such as quinones have received increased attention as promising electrode materials for rechargeable batteries. However, experimental determination of the crystal structure of intermediate species formed during the discharge/charge cycle can often be challenging. Incomplete X-ray diffraction patterns can also lead to difficulties in crystal structure determination for ROMs used in batteries. Use of a semiempirical electronic structure method …

The Trial Of Socrates, Jonathan Van Patten

Faculty Publications

In many important ways, the trial of Socrates was not just the trial of the century, nor even the trial of the millennium. It predated the trial of Jesus, which is important for many other reasons, but Socrates’ contribution to how we think about justice and the rule of law is without equal. This Article explores the ways that this fifth-century B.C. trial, located geographically on the margin of what came to be known as the West, is at the center of what makes us a civilization. It is not simply about the drama, nor the politics of free inquiry, …

Detecting And Repairing Conflicting Constraints In Co-Trained Physics-Informed Neural Networks For Composite Curing Processes, Cooper J. Evans

Dissertations, Master's Theses and Master's Reports

Composite materials have become a critical component of modern manufacturing, especially in the automotive and aerospace industries. The curing process for these composites has been modeled using a variety of partial differential equations representing the heat transfer and composite curing kinetics. Optimizing the applied temperature profile is critical for maximizing the efficiency and capacity of composite part manufacturers. Constraints must be placed on the inputs and outputs of the model, including but not limited to, the applied temperature profile, part temperature, and final degree of cure. Conflicting sets of constraints are easy to unknowingly impose due to the highly coupled …

Torque-Based Detection And Isolation Of Bucket-Specific Load Variations In A Continuous Bucket Ladder Excavator, Mason R. Krause

Dissertations, Master's Theses and Master's Reports

Understanding how cutter geometry, material, and operating conditions influence excavation performance is critical for the design of lunar surface systems operating in regolith environments. This work presents a torque-based methodology for detecting and quantifying bucket-specific load variations in a continuous bucket ladder excavator. A nine-bucket excavator was constructed to record drivetrain torque while operating in a regolith simulant over multi-day test periods. Each bucket featured a unique combination of cutting edge material and geometry. A method was developed to separate the continuous torque data into individual excavation events, enabling identification of individual bucket interactions. Analysis of the resulting event-based dataset …

A 725-Bp Quadruple Repeat In The Promoter Of Smmyb113 Is Associated With Light-Independent Anthocyanin Regulation In Eggplant, Zhilei Xia, Meng Yang, Yinggemei Huang, Bingxin Yu, Tingxia Wan, Duanhua Wang, Qian Li, Manoj Sapkota, Shuangshuang Yan, Bihao Cao, Zhengkun Qiu

Horticulture Faculty Publications

Eggplant exhibits a diverse range of fruit colors, making it an excellent model for studying fruit pigmentation and its genetic regulation. While genes responsible for green and photosensitive purple fruit have been identified, the genetic basis of the nonphotosensitive (NPS) fruit trait in eggplant has remained elusive. In this study, we characterized a major quantitative trait locus (QTL), SmNPS10.1, on chromosome 10 using QTL-seq. By combining linkage-based gene mapping with progeny testing, we fine-mapped SmNPS10.1 to a 33.58-kb interval, within which we identified SmMYB113, an R2R3-MYB transcription factor that regulates anthocyanin biosynthesis, as the candidate gene. Sequence analysis …

Adding Family Complications To Birthright Citizenship, Scott Titshaw

Articles

On the first day of his second administration, President Trump issued an executive order purporting to restrict citizenship of U.S.-born children based on their parents’ citizenship or immigration status. In the process, it discriminates between mothers and fathers and adopts genetic definitions of “mother” and “father” to exclude any parent, who is not the child’s “immediate … biological progenitor.”

Courts and scholars have condemned this attempt to restrict birthplace citizenship as a violation of both the Fourteenth Amendment and the Immigration and Nationality Act. Yet there has been little, if any, discussion of the new family-based conditions in the order. …

The Love We Draw, Caleb Van Cleave

English Honors Papers

This thesis contains a completed story about navigating how to continue loving someone after one’s understanding of their being has changed in a way that makes them suddenly unfamiliar. It is a story that asks its characters if they are willing to adjust their perceptions of one another in order to remain connected or if they would rather sacrifice that growth in favor of chasing prior ideals. It is a story about seeking affection but no longer feeling certain of where to find it.

My goal for this thesis was to focus on fragmentation within a family dynamic, specifically during …

“But I’M Glad I’M Not A Hog!”: The Pig, The Laborer & “Humanity” In Animal Farm (1945) & The Jungle (1905), Madelyn Bell

English Honors Papers

This thesis places The Jungle and Animal Farm in conversation with one another to examine how each text engages, reframes, and complicates Marxist conceptions of labor, class, and (de)individuality through the figure of the pig. Beginning from the pig’s marked similarity to humans – its intelligence, sociality, and symbolic proximity – the analysis considers how this likeness makes the pig a particularly charged symbol for negotiating the moral and conceptual boundary between human and animal, inviting a reading in which human structures are reflected back through the animal form. Attending each novel’s distinct concern with socialism – Sinclair’s investment in …

Hear & Now: Culturally Responsive Music Education Through Digital Audio Workstations & Musique Concrète, Benjamin T. Connolly

Pitzer Senior Theses

Hear & Now: Culturally Responsive Music Education Through Digital Audio Workstations & Musique Concrète is a two-part ethnomusicological study of how the capacities and affordability of modern electronic instruments could be utilized within school curricula as an affordable alternative to traditional music classes. I explore the musique concrète movement from mid-20th century France, aiming my examination towards the movement’s emphasis on the materiality of sound production and utilization of modern technology during the composition process. From there, the paper transitions into a study on the affordances of contemporary music technologies through a series of interviews with electronic composers, tracing the …

When Hearts Beat In Two Languages: Enabling Access To Biliteracy Pathway Recognitions For Latine Linguistically Expanding Learners (Lexls) In K-8 Schools Across A Southern California School District, Mayra C. Orozco

CGU Theses & Dissertations

This qualitative nested case study examined how Biliteracy Pathway Recognitions (BPRs) are implemented and accessed for Latine Linguistically Expanding Learners (LExLs) in one Southern California school district. Although California has expanded opportunities for students to earn recognitions that value bilingualism and biliteracy, little research has examined how these policies are implemented at the elementary and middle school level and how families navigate access to these opportunities. Guided by Honig’s (2006) policy implementation framework of policy, people, and places and Yosso’s (2005) Community Cultural Wealth (CCW) model, this study explored how district and school personnel implemented BPR policies and how families …

Blazing Turquoise And Coral Light Jewels Of Veiled Empowerment: Buddha Ye Shes Mtsho Rgyal (ཡེ་ཤེས་མཚོ་རྒྱལ) And Saint Hildegard Von Bingen In The Lotus Of Ever-Excellent Feminist Dialogue, Janice Leigh Poss

CGU Theses & Dissertations

This Women's and Gender Studies in Religion dissertation seeks to restore awareness of women's religious leadership using the actual embodied experience of Yeshe Tsogyal and Hildegard von Bingen embedded in the philosophical terms Erlebnis (German), Padartha/Bhava (Sanskrit), and srid pa (Tibetan). Brief definitions are: Erlebnis as enthusiastic, lived experience and awareness, Padarthas as categories of real things or actualities, Bhava as the act of emotional or spiritual feeling, and Srid pa as becoming in possibility. Drawing on the above four terms encapsulated in a feminist transnational and intersectional methodological framework, this project reinforces women’s authority and influence in religion as …

On The Influence Of Faraday Waves On Transport In Resonant Acoustic Mixing, Preston David Silverstein

CGU Theses & Dissertations

Resonant acoustic mixing (RAM) uses low frequency high acceleration oscillatory forcing to combine fluids, particles, and powders. Although progress has been in adjacent RAM fields, there are still gaps in understanding how Faraday surface instabilities affect momentum transport to the bulk fluid and particles therein. This work investigates the energy pathways that an oscillatory mixer has and connects surface deformation to bulk rotational flow and particle forcing. This study is conducted in three phases. In phase 1, a thermodynamic first- and second-law analysis couples the surface features with the scale of subsurface rotational features. Experimental surface measurements showed that for …

John: A Samaritan Gospel, John Colin Stringfellow

CGU Theses & Dissertations

The Gospel of John is enigmatic; scholars have sought to identify its distinctive features. Is it influenced by Hellenistic culture, Gnosticism, Dositheism, or is it an editorial compilation? These distinct characteristics have led scholars to speculate about the intended recipients of the Fourth Gospel. Identifying the audience is crucial in deciphering these distinct characteristics. Why did the author(s) use specific literary techniques and devices? Why were particular stories selected? This dissertation does not seek to dismiss the existing scholarly analyses that have identified the recurring themes and structure of the Gospel of John; instead, it prompts the question, "Why?" Understanding …

Chicano Studies Courses: Latina/O Student Engagement In Community Colleges, Marisol Celeste Madrigal Uribe

CGU Theses & Dissertations

Community colleges play a vital role in expanding access to higher education for historically marginalized students, particularly Latina/o and first-generation college students. However, many students arrive carrying the effects of cultural erasure, racial marginalization, and deficit-based schooling experiences that shape their academic engagement, sense of belonging, and future aspirations. This qualitative study examines how Chicana/o Studies courses foster student engagement, identity development, belonging, and future orientation within the community college context. Guided by Critical Race Theory (CRT) and the concept of racial microaffirmations, the study conceptualizes Chicana/o Studies as a transformational educational space that affirms students’ lived experiences, challenges Eurocentric …

Institutional Reform In Support Of Xi’S Anti-Corruption Campaign, Rixin Wen

CGU Theses & Dissertations

Corruption remains a pervasive challenge that distorts markets, undermines public service delivery, destabilizes social order, and erodes governmental legitimacy. In China, anti-corruption has been a recurring policy priority since 1949, culminating in Xi Jinping’s sweeping campaign launched in late 2012. Conceptualizing corruption through a principal–agent framework, this dissertation argues Xi Jinping’s anti-corruption campaign represents not merely an institutional inflection point in China’s supervisory architecture substantially enhancing enforcement capacity and elite discipline, but also the enforcement–perception interactive change, reproducing an asymmetry between punishment and public perception under the unvarying political foundation. This study employs a multi-method research design that integrates institutional …

Reading The Birds: Critical, Multimodal, And Queer Meaning-Making In Literacy Teacher Education, Kris Benefield

CGU Theses & Dissertations

This qualitative dissertation explores critical, multimodal, and queer literacies and related pedagogies in teacher education. In it, I engage in both critical analysis and theorizing at the intersection of teacher education, literacy, and pedagogy, producing insights and tools that may be of use to teachers, teacher-educators, and researchers interested in resisting oppression in and through literacy and composition education. The findings contribute to the research on literacy teacher education by detailing the situated processes involved in both critical meaning-making and pedagogical enactment among a group of K-12 teachers in and beyond two literacy methods courses. I draw on thematic analysis …

Shared Words, Divided Worlds: Moral Language And The Struggle For Meaning At The Claremont Colleges During The Vietnam War, 1965-1969, Haley Freeth

CGU Theses & Dissertations

This thesis examines the Vietnam War-era campus conflicts at the Claremont Colleges as a profound struggle over the meaning and ownership of moral and political language. Rather than interpreting antiwar and prowar activism as expressions of fundamentally opposed value systems, this study argues that students and administrators alike engaged in an ongoing contest to define ideals such as democracy, responsibility, and conscience. Through a micro-historical lens, the project analyzes how these contested vocabularies were invoked, reinterpreted, and performed in protests, counter-protests, and administrative policies. Drawing from a wide array of archival sources—including student newspapers, protest ephemera, administrative records, and visual …
