The Torii Project
This is a summary of the Torii Project: how the project came to be, and the process behind the preconstruction of installing the structure. A Torii is a Japanese gate structure in Japanese Shinto practices, as the structure is a frame for a significant space. The project was initially started by the Japanese Student Association, and has grown over time become an interdisciplinary design build project involving architects, civil engineers, landscape architects and construction management majors. The design came from Cal Poly Architecture Alumni Amir Hossler who has studied the construction of Toriis in Japan and was the main source of information for the design. In order to stay committed to the project’s promotion of diversity and inclusion, major Japanese American communities were sought for their approval of the project as stakeholders, which included the Japanese Student Association, the Nikkei Student Union, the SLO Buddhist temple and the Hayashi Family. With help from CAED support shop staff and architecture student Laura Kuffner, process plans were designed and developed as the materials were procured. It will also discuss the permitting process, and the difficulties and roadblocks that slowed progress and the plans going forward to install the final version of the Torii
Mobile Firewall System For Distributed Denial Of Service Defense In Internet Of Things Networks
Internet of Things (IoT) has seen unprecedented growth in the consumer space over the past ten years. The majority of IoT device manufacturers do not, however, build their products with cybersecurity in mind. The goal of the mobile firewall system is to move mitigation of network-diffused attacks closer to their source. Attack detection and mitigation is enforced using a machine that physically traverses the area. This machine uses a suite of security tools to protect the network. Our system provides advantages over current network attack mitigation techniques. Mobile firewalls can be deployed when there is no access to the network gateway or when no gateway exists, such as in IoT mesh networks. The focus of this thesis is to refine an explicit implementation for the mobile firewall system and evaluate its effectiveness. Evaluation of the mobile firewall system is analyzed using three simulated distributed denial of service case studies. Mobility is shown to be a great benefit when defending against physically distant attackers – the system takes no more than 131 seconds to fully nullify a worst-case attack

The Construction of Khovanov Homology
Knot theory is a rich topic in topology that studies the how circles can be embedded in Euclidean 3-space. One of the main questions in knot theory is how to distinguish between different types of knots efficiently. One way to approach this problem is to study knot invariants, which are properties of knots that do not change under a standard set of deformations. We give a brief overview of basic knot theory, and examine a specific knot invariant known as Khovanov homology. Khovanov homology is a homological invariant that refines the Jones polynomial, another knot invariant that assigns a Laurent polynomial to a knot. Dror Bar-Natan wrote a paper in 2002 that explains the construction of Khovanov homology and proves that it is an invariant. We follow his lead and attempt to clarify and explain his formulation in more precise detail
Discourse Analysis in Engineering: Investigating Patterns in Brainstorming Conversations
Brainstorming is a critical part of the engineering design process and can have a significant impact on the outcomes of the overall project. While research has studied the outcomes of brainstorming and the ideas that teams generate, the role that language and conversation play in these activities is still relatively underexplored. Observing the different ways people use specific types of discourse can reveal how conversations can affect brainstorming itself. To that end, this research aims to answer the following questions:
1) What are the different kinds of discursive moves that students make during engineering brainstorming activities?
2) What patterns or themes emerge among these discursive moves?
We collected data by recording conversations that took place during team brainstorming activities with engineering students. These conversations were transcribed, and we used discourse analysis to code our data according to the speaker\u27s intent. We combined quantitative and qualitative analysis to identify and explore correlation patterns within these conversations.
Three prominent themes emerged from our analyses: Active Engagement, Group Rapport, and Exploring the Problem. These themes highlight the range of different conversational elements that work together to support effective brainstorming discussions. Engineers and engineering educators can be mindful of the way that they frame their brainstorming activities so that the team’s discourse encourages more active engagement, stronger group rapport, and deeper exploration of the problem at hand
United States Army Corps of Engineers Info Session at California Polytechnic State University San Luis Obispo
Gabriel Vesneski facilitated an Info Session on Thursday, November 2, at California Polytechnic State University, San Luis Obispo for the United States Army Corps of Engineers Sacramento District Civil Works. Three guest speakers from the Sacramento District Civil Works office presented their educational background, experience as employees for the Corps of Engineers, occupational benefits, and finally opened a question-and-answer forum for the students attending the Info Session. Upon completion of the Info Session, a survey was provided for attendees, in order to track interest in employment or internship opportunities provided by the United States Army Corps of Engineers. Finally, there was a networking portion for all students interested in internship or employment opportunities. This project was designed to expose prospective students to career opportunities provided by the Corps of Engineers, and to foster a relationship between the United States Army Corps of Engineers and Cal Poly Construction Management. In the future, it is encouraged for similar info sessions to be conducted for the students attending Cal Poly either as construction management or engineering undergraduates
A Numerical Modeling Analysis Of The San Francisco Bay And Sacramento-San Joaquin Delta: Riverine, Tidal, And Wind Processes
The primary motivation of this study is to analyze the 1D-2DH hydrodynamic model of the San Francisco Bay and Sacramento-San Joaquin Delta (SFBD) outlined in Nederhoff et al. (2021). I compared model water level data to 70 tidal records from the National Oceanic and Atmospheric Association (NOAA), the United States Geological Survey (USGS), the California Data Exchange Center (CDEC), and from local municipalities throughout the Bay Area to investigate how the model captures water levels and tidal constituent amplitudes. While the Nederhoff et al (2017) model analyzed an extended time period from 1950-2019, I analyzed M2 amplitude and tidal water levels for the water year of 2017 (WY2017) with a larger dataset that extended into the Sacramento-San Joaquin Delta. Because WY2017 was a high river flow year for the Sacramento Delta, the model was able to be evaluated throughout a large range of flow regimes.
I used harmonic analysis through the MATLAB package UTide (Codiga et al. 2011) to assess the model’s ability to replicate M2 amplitudes. I assessed the error for these M2 values as well as for tidal water levels. The average RMSE for M2 amplitude is 0.111 m across the entire model domain during WY2017, performing fairly consistent throughout the model. The one exception being the shallow and complex Grizzly Bay, which performed significantly worse, with RMSE values around 0.5 m. The model better replicated water levels in the 2DH grid representation of the San Francisco Bay (
Attempts to improve the model were mostly unsuccessful. I tried to increase the grid resolution at the Carquinez Strait to improve tidal propagation upstream, but altering the grid caused the coupling between the 2DH grid and 1D network to detach. This prevented the propagation of water flow in either direction at the coupling near Collinsville. The software required to fix this coupling was non-standard and unavailable for my usage, so I was unable to resolve the issue. I also attempted to create a new wind forcing file using in-situ data rather than the ERA5 reanalysis. This new wind forcing made negligible difference in water level and M2 model skill.
An experiment in removing river flow showed that riverine impacts on elevating extreme water levels only have effects (\u3e0.05 m) east of the Carquinez Strait. Extreme water levels west of this point in the San Pablo, Central, and South Bays are dominated by tides, storm surge, and to a lesser extent local wind. A decrease in tidal amplitude by river flow potentially decreases flood risk in some parts of the Bay during times of high outflow from the Sacramento-San Joaquin Delta. I also investigated maximum equilibrium effects of constant wind in the two prevailing wind directions (southerly and westerly) of the San Francisco Bay. The wind setup effect become more prominent (\u3e0.05 m) at and above a steady 10 m/s in both directions. This study also showed that wind likely exerts a small influence on tidal properties, especially for winds greater than 10 m/s
Python Manual: a Learning Guide for Structural Engineering Students
This Python programming manual is a resource to assist architectural, civil, or structural engineering students as they learn to create scripts to solve various structural analysis and dynamics problems. Beyond providing guidance on Python libraries that enable numerical and symbolic mathematics (NumPy, SciPy, SymPy), the manual also focuses on the creation of tabular and plot outputs useful to communicate results through technical reports (Pandas, Matplotlib).
The content of this document was developed based on detailed review of curriculum for three architectural engineering computing courses typically offered to upper class students at Cal Poly, San Luis Obispo as well as surveys with students who had completed the courses and industry members. The authors recognize that programming is challenging enough without having to use a textbook with example problems from other unfamiliar technical fields or where each Python library has its own separate documentation website to navigate.
The document includes 24 chapters on how to use both the Spyder integrated development environment and a range of Python programming topics. The chapters include explanations, graphics, and examples related to structural engineering so that students can follow and apply programming skills to their coursework, but also appreciate its broader utility for their careers. The goal with this resource is to address students’ common knowledge gaps in Python along with building confidence and motivating them to learn how to program, better equipping them for success in the computing courses and in leveraging programming as a tool when they enter industry
