Vlsi Spike Encoder For Spiking Neural Networks With 4-Bit Sar Adc, Jack Marshall, Wyatt Tack, Cameron Young, Ryken Thompson

Electrical Engineering

A spike encoder forms the interface between sampled data, such as image data or a sensor signal, and a spiking neural network by converting numerical input samples into discrete spike events. Unlike conventional artificial neural networks, spiking neural networks use spare, even-driven computation instead of continuous-valued activations. This makes them attractive for low-power embedded systems, biomedical electronics, and other edge applications where energy consumption, physical area, and thermal limits are important design constraints.

This project develops a modular spike encoder architecture for spiking neural networks with selectable support for temporal, rate, multi-spike, and delta encoding. Prior work has shown that …

Lidar At Poly Canyon, An Binh Chuong

Architectural Engineering

Poly Canyon serves as a living laboratory that reflects Cal Poly’s “Learn by Doing” philosophy through a collection of student-designed and student-constructed structures. Among these is Fratessa Tower, a reinforced concrete observation tower distinguished by its tripod support system, cable-suspended observation deck, and steel spiral staircase. The tower’s unconventional geometry and exposed structural system present unique challenges for documentation, making it well suited for evaluating modern reality-capture and modeling techniques.

This project focused on creating an accurate as-built Building Information Model (BIM) of Fratessa Tower using LiDAR-based scanning, field verification, and Autodesk Revit. Point cloud data were processed to reconstruct …

Reinforced Concrete Design Fundamentals, Belen Stephanie Martinez Espinoza, Estevan Jacob Perez

Architectural Engineering

Hispanic workers make up a large and growing portion of the construction workforce in the United States; particularly in California, the percentage of construction workers who are Hispanic is estimated to be about 55% as of 2021 (Elkins). Many of these workers are Spanish-speaking, yet there is still a gap between technical engineering design and what is understood and applied in the field. One major reason for this gap is the lack of clear bilingual resources. To bridge the gap, a 48-page bilingual booklet titled Reinforced Concrete Design Fundamentals (Fundamentos del Diseño de Concreto Reforzado in Spanish) was created. This …

Flexural Behavior And Failure Mode Assessment Of Concrete-Encased Steel Beams Constructed With Experimental Cardboard Formwork, Luke Robert Jones, Drew Takeshi Kawaguchi

Architectural Engineering

This project investigated the flexural behavior of a concrete-encased W8×13 steel beam detailed without conventional longitudinal reinforcement and constructed using an experimental cardboard/Masonite formwork system. A bare steel control specimen and an encased composite specimen were tested under identical loading conditions to evaluate the effects of concrete confinement and welded transverse reinforcement on lateral-torsional buckling behavior. Results showed that the encased specimen remained laterally stable and developed flexural cracking and concrete crushing rather than the lateral-torsional buckling observed in the control beam. The study also demonstrated that the modified cardboard formwork successfully contained the concrete without the seepage failures observed …

Improving The California Boulevard Railroad Underpass: A Feasibility Study Of Persistent Barriers And Practical Improvement Strategies, Jacee D. Carpenter

Construction Management

The California Boulevard railroad underpass in San Luis Obispo has served as an informal pedestrian route for Cal Poly students since pedestrian access across the adjacent railroad tracks was restricted in 2009. Despite its frequent use, the underpass presents challenges related to lighting, drainage, surface conditions, and seasonal flooding that affect safety and accessibility. Previous studies documented these concerns and proposed improvement concepts; however, no significant physical improvements have been implemented. This project evaluates the factors contributing to the lack of improvements and examines practical strategies for enhancing the underpass within existing regulatory, environmental, and jurisdictional constraints. Methods included a …

Political Inconsistency Detection Across Legislative Speech And Public Communications, Scott M. Pramuk

Master's Theses

Political actors communicate about legislation across multiple contexts, including committee hearings, recorded votes, and public-facing press releases. Differences between these forms of communication can provide useful signals for journalists and researchers seeking to understand how legislators present policy positions to different audiences.

This thesis extends the Digital Democracy Project, a legislative transparency initiative that provides access to California state legislative hearing transcripts, voting records, and related legislative data. Specifically, this work incorporates publicly accessible, legislator-authored news releases into the Digital Democracy Database and develops a pipeline for analyzing legislative communication across multiple sources. The system collects news releases from California …

Perception Is Reality: Evaluating Transportation Satisfaction And Utilization In Continuing Student Housing At Cal Poly, Lucas Owens

Master's Theses

As higher education institutions increasingly mandate on-campus living to foster student success, the built environment becomes a critical determinant of daily mobility. California Polytechnic State University (Cal Poly) is transitioning to a two-year residency requirement and tightening vehicle restrictions. This thesis evaluates how the spatial and built-environment realities of peripheral housing complexes in Cerro Vista Apartments and Poly Canyon Village shape student transportation satisfaction and utilization, and emergency evacuation preparedness.

Employing a mixed-methods approach, this research triangulates data from 79 student surveys and 10 semi-structured interviews. The findings indicate that supplementing traditional metrics of proximity with localized spatial data presents …

Research For Structural Change: An Abolitionist Teaching Activity For Early-Career Scholars, Sophia Sarantakos, Shannon Sliva

Feminist Pedagogy

In recent years, social work practitioners, educators, and scholars have increasingly wrestled with the harmful history of the profession, and sought ways to align the field with the anti-oppressive principles it has long espoused. One expression of this struggle is a growing interest in prison-industrial complex (PIC) abolition, primarily among social work students and early career scholars, who are eager to study this critical theory of change and apply it to the various domains of social work practice and research (e.g., schools, family policing, healthcare, the legal system, and beyond). As social work educators and scholars whose work is centered …

Creating Abolitionist Classroom Environments And Three Abolitionist Learning Activities, Marina Bell

Feminist Pedagogy

In this paper I describe some of the approaches I have developed over the past six years of abolitionist teaching in the classroom. I will focus on three activities for helping students grapple with abolitionist concepts, principles, and values experientially, with the goal of generating conversation about some of their most challenging aspects, and working through emotions around them. Specifically these exercises are: 1) Distinguishing between carceral and abolitionist reforms, 2) What do we do with “the dangerous people” and our feelings about them?, and 3) A mutual aid exercise in which I have students identify and choose together what …
