Miniature Train Engine

This report details the redesign of the Mini Train Prop for the SLO Civic Ballet’s The Nutcracker, aiming to create a lighter, more user-friendly, and easily maneuverable train. The Final Design Review (FDR) includes the design process, manufacturing plan, and justifications for decisions made. Key improvements are reducing the train\u27s weight, automating the fake wheels, and enhancing maneuverability with a neutral pin and lever system. In this report we detail the significant changes since the Critical Design Review (CDR). The implementation covers procurement, manufacturing, and assembly, while design verification ensures compliance with cost, weight, turn radius, and structural integrity specifications. Testing confirmed the redesigned train meets all requirements. The document concludes with project outcomes and recommendations for further improvements. Finally in the appendix a user manual, risk assessment, final project budget, design verification table, and testing procedures can be found

Cal Poly Fluid Power Vehicle Challenge 2024

In this Final Design Review, the Cal Poly Fluid Power Vehicle Team competed in Norgren’s 2024 Fluid Power Vehicle Challenge. The design need of the competition was for college teams to compete with human-powered, hydraulic-driven vehicles in an endurance race, a sprint race, an efficiency race, and a regenerative power race. The competition need was to design a vehicle to win in as many races as possible, achieving the highest overall score and winning the competition. With a design emphasis on the endurance and sprint race, the Cal Poly team designed a fluid power system that fastened to a purchased tricycle. The tricycle converted mechanical rotational power to fluid power that could be stored, released, or directly used at a rear-driven wheel using a mechatronics control system. The best results achieved during testing and competition were a 10:49 mile time (testing), 86 ft distance traveled on regenerated power collected from a 100ft deacceleration (competition), a 22% vehicle efficiency (competition), and a 39 second sprint time to cover 500 ft (testing). The rear chain fell off and eventually snapped during the competition, preventing the team from achieving high marks in the sprint and endurance race, but the vehicle performed 4th in the efficiency race and 5th in the regen race. A major takeaway from the competition was that a purchased frame build was the best design direction to focus on the hydraulic and pneumatic system implementation. The two major recommendations for next year’s vehicle design using the same platform are an improved mechatronics system that efficiently switches between drive modes and a rear chain tensioner to prevent the chain from skipping teeth and falling off

TMHA Parking Lot Project

The Transitional Mental Health Association (TMHA) parking lot project in Edna, California, aimed to construct a 4,400 SF decomposed granite (DG) parking lot for the TMHA’s Youth Treatment Program (YTP). TMHA’s YTP involves giving children in a transitional housing state a safe and welcoming place to live while addressing the problem of unhoused children in San Luis Obispo County. This initiative involved extensive grading, forming, surveying, and installing the necessary infrastructure to ensure both functional and aesthetic improvements for the facility. The project was meticulously planned and executed during the Spring, 2024 quarter, with a budget of approximately $4,285. The successful completion of this project required careful coordination, resource management, and problem-solving. It highlighted the importance of accurate estimation, proper equipment usage, and community engagement. This paper details the project\u27s conception, methodology, outcomes, and lessons learned, providing a thorough overview of the processes and experiences involved. It serves as an example of how academic knowledge can be applied in real-world settings to achieve significant community benefits. The project also underscores the value of hands-on experience in enhancing professional skills and readiness for future challenges as students eventually become industry professionals

Review: C-type Natriuretic Peptide And Amphiregulin On Bovine Oocyte Maturation And Pitfalls In The IVF Laboratory.

The production of embryos has been described as a revolutionary process with the ability to make cattle systems more successful. However, despite constant research done in the field of embryology, there remains a discrepancy between the quality of in vitro produced (IVP) and in vivo derived (IVD) embryos. This difference is potentially associated with the lack of synchronization between nuclear and cytoplasmic maturation events within the oocyte, which is carefully mediated in the ovarian environment and the cumulus oocyte complex (COC). The purpose of this thesis was to utilize a pre-maturation culture system to keep oocytes in an arrested germinal vesicle (GV) state before subjecting them to maturation. In the first half of the experiment, oocytes were pre-matured in C-type natriuretic peptide (CNP) supplemented medium for 12 hours. Following pre-maturation, oocytes were transferred to amphiregulin (AREG) for another 12 hours to develop. This procedure is known as CAPA-AREG. After fertilization and a 7- day culture, embryos were assessed for cleavage rate and blastocyst rate. Embryos were also subjected to staining in order to evaluate lipid content and mitochondrial activity via confocal microscopy and ImageJ software. Hurdles in acquiring data also encouraged an assessment on the IVF laboratory and how procedures can be optimized. Overall, embryology lab procedures must be strictly followed, and the laboratory environment must be maintained to the best of the staff’s ability to increase success rates. Due to mishaps in the laboratory, the effectiveness of CNP and AREG on improving bovine oocyte maturation and embryo development is still inconclusive. Further research is required to determine if CNP and AREG can be utilized in future bovine IVF procedures

A Study of Commuting Conditions for Construction Professionals in the San Francisco Bay Area

This paper investigates the commuting experiences of workers in the San Francisco Bay Area, with a focus on construction industry professionals. Numerous scientific studies and reports have been done regarding both traffic congestion in the Bay Area and commuting conditions for construction workers. By comparing points of information on Bay Area workers like their job type, commute length and commute satisfaction, this study aims to uncover correlations and understand who is affected the most by traffic congestion. After extensive surveys and interviews of Bay Area workers, average commute times were calculated and reported for several industry subsets, along with averages for specific positions within the construction industry. It was found that construction industry workers have the worst commutes in the Bay Area, and trade workers like carpenters and electricians commute the most of any job type, regardless of industry. These conditions are brought on by the combination of high demand for construction professionals to develop real estate in the urban centers, suboptimal transit options, and a lack of available affordable housing. With millions of people already living there and more on the way, the sprawling San Francisco Bay Area faces a lack of transportation efficiency that must be addressed
