Investigating Engineering Students Responses to Failure
No full textLearning from failure is an essential component of both learning and practicing engineering. However, failure is often stigmatized and avoided in engineering education. This project aims to better understand how to support students throughout their engineering education to help them learn from their failures, rather than become frustrated or discouraged by them. The project will build on prior research in students’ responses to failure experiences to specifically analyze students who respond to failure in different ways and build on these experiences to help students in similar situations. During the SURP project, the student will use qualitative methods to analyze interview data from students at Cal Poly who have experienced failure and persisted in engineering. The interview questions focus on students’ experiences both in and out of the classroom that have supported them through learning from failure and we will use qualitative data analysis methods to analyze students’ experiences. The aim is to compile the results of the analysis to present to students and instructors at Cal Poly, as well as prepare a conference paper to report the findings to a larger audience. These results have the potential to support students to persist through failure experiences and to develop ways for instructors and institutions to support learning from failure
Analyzing Patterns in Hofstede’s Cultural Dimensions Towards Individual AI Receptiveness for Affective Experiences
No full textThe use of artificial intelligence (AI) has significantly advanced efficient decision-making, with trust in algorithmic decisions shown to vary by cultural upbringing [1]. As AI becomes increasingly embedded in everyday life, it is essential to examine how cultural values affect trust in AI in subjective contexts that extend beyond purely quantitative analysis, like the personal interpretation of art. This work utilizes Hofstede’s cultural dimensions to investigate potential patterns in receptiveness towards AI predictions during art interpretation, providing insight into individual susceptibility to bias in AI-assisted affective analysis.
The study leveraged a cultural dimension survey and a custom Java program connected to an electroencephalography (EEG) headset, collecting Pleasure-Arousal- Dominance (PAD) estimates of participants’ emotional subconscious with self-reported quantifiable data. This was conducted as participants viewed artwork before and after receiving predictions from a machine-learning model, allowing us to analyze changes triggered by the presence of AI. Through regression modeling, it was found that none of the cultural dimensions had a statistically significant relationship with the number of changed answers. However, 26 out of the 35 participants acknowledged experiencing self-reflection or persuasion when exposed to such recommendations. While the quantitative data did not reveal a measurable influence from espoused cultural dimensions, the qualitative insights affirm that AI presence can still exert affective influence by promoting introspection, regardless of one’s cultural dimensions. The exploration of how these findings align or expand upon prior research reveals opportunities for further investigation within the psychological elements of AI adoption
Circular Restricted Three Body Manifold Trajectories via Koopman Operator Theory
Get PDFThere are a multitude of computational techniques capable of modeling the behavior of nonlinear dynamic systems over time. In the field of astrodynamics, the most frequently used tools are numerical integrators, specifically Runge-Kutta algorithms. These algorithms have successfully produced numerous two-body trajectories, as well as an increasing number of three-body trajectories when two-body dynamic models fail to produce Δv values within the realm of mission feasibility. Koopman operator theory is an alternative method for modeling nonlinear dynamic behavior that captures an approximation of a nonlinear dynamic system on a defined basis in the Hilbert space. The Koopman operator is an infinite dimensional linear operator capable of evolving all observable functions of the state, and when the observable is chosen to be the identity observable, can evolve the states themselves. In this thesis, Koopman operator theory is applied to the circular restricted three body problem to solve for halo orbits in the Sun-Earth system, as well as their resulting manifold trajectories. The goal is to possibly expand the initial trajectory design tools available to mission designers as the need for nonlinear three body solutions increases. A complex-normal Hamiltonian dynamic model and Hamiltonian dynamic model are used with a third order Richardson polynomial for the nonlinear dynamic representation. The implementation of the complex-normal Hamiltonian is found to be highly susceptible to error and ill suited to an initial trajectory design application. The implementation of the Hamiltonian is much simpler and using this dynamic model, the Koopman operator produces partial halo orbits, but diverges before a full period is achieved. The solutions become less accurate as the halo amplitude increases, and as the solution order decreases. Manifolds are successfully computed along the converged portion of the trajectories, but their trajectories diverge as well before long term behavior can be identified. The lack of converging solutions from the Hamiltonian model is attributed to an insufficient basis. The computational burden required to form a sufficiently large basis that produces a converging solution exceeds the capacity of the computer used for this analysis and what is desirable for low-cost initial trajectory design. Thus, Koopman Operator Theory is deemed an ineffective initial trajectory design tool
Moonlight Matcha Process Book
Get PDFAs matcha continues to rise in popularity across the United States, there are significant gaps in consumer awareness regarding its health benefits and cultural significance. Moonlight Matcha, a fictitious brand developed for my senior project, seeks to bridge those gaps by educating consumers about the wellness benefits of matcha while featuring a modern, appealing design that resonates with a broad audience. This project has been especially meaningful because it allowed me to explore the full process of building a brand from the ground up – from brand strategy and storytelling to packaging development and user experience (UX) design. It brings together all of the skills I’ve developed through my Graphic Communication coursework, including marketing, branding, design, and UX. By creating a cohesive brand that informs and engages consumers, I gained deeper insight into what it takes to design a brand that feels authentic and approachable. Additionally, as someone who drinks matcha daily, this project gave me the exciting opportunity to create a brand that reflects both my personal connection to match and my creative vision
Development of Planetary Drive System For Formula SAE Electric Race Car
Get PDFHub motors are compact electric motors mounted directly on each outboard wheel hub. Utilized in Formula SAE and Formula Student vehicles, this configuration offers several advantages over traditional drivetrains, including packaging optimization within the chassis, vehicle traction, and improved efficiency. Although hub motors are not yet common in 4WD vehicles, they are being explored for use in EVs and may become more common in the future. Every year, Cal Poly Racing FSAE designs and builds a formula-style race car. To improve drivetrain performance, the team is investigating the achievability of a hub motor 4WD drivetrain, requiring extensive research, development, and testing. This project focuses on designing a planetary gearbox and its requisite housing for integration with a hub motor 4WD system. The team has developed a novel suspension and drivetrain upright design to accommodate this system and evaluate its performance before full vehicle integration.
The planetary gearbox is derived from pervious Cal Poly Racing Formula upright designs, utilizing their trademarks of in-house manufacturing, requirements driven design. The assembly features 3 component compound gear sets, a ring gear, and sun gear. Additionally, the upright has been adapted to support the AMK hub motor with mounting features on the upright for an adapter plate which will support both the AMK hub motor and potential a cooling jacket. The hub was also revised to accommodate the gearbox structures while maintaining its signature features such as mounting face for the OZ magnesium center lock wheels as well as brake rotors and hub bearing seat.
The gear fatigue analysis was conducted using AGMA standards, supported by an interactive spreadsheet to evaluate design trends and their impact on gearbox performance. COTS (Commercial off the shelf) components were used, when possible, to prioritize two main factors: (1) reduced in house manufacturing utilization and, (2) readily available components for purchase. This allowed the team to purchase both planet gears, and all gearbox hardware
