The vast and deep conditions of the ocean still contain many objects that have not been explored. Based on the type of autonomous underwater vehicle (AUV) device design, it consists of types that can drift, glide, and can propel itself in water. Types of AUV without propellers (nonpropelled, drifter). or glider), can float without thrusters or glide up and down the water by changing its buoyancy. This AUV uses little or no battery power compared to propeller-driven AUVs, but cannot perform as many maneuvers. Variable Buoyancy System used in different types of underwater craft, designed and built for specific rides and applications. Therefore, each system is completely different from the others. This research focuses on systems that raise and lower volume, using components such as diaphragms, bladders, and bellows. It is possible to use a diaphragm for a buoyancy engine to make the vehicle easier to fabricate. The aim of this research is to determine the magnitude of deformation of the diaphragm made from silicon rubber and EPDM (ethylene propylene diene monomer) with varying thickness of 0.5 mm; 1mm and 2mm. Through the Finite Element Method approach to obtain deformation analysis modeling, EPDM material provides higher deformation than using silicon material. However, for pressures of no more than 0.5 bar, using a rubber thickness of 0.5 mm is not suitable. So the appropriate application for Gliders is 1 mm thick.

“The Game Was Ruined For Me There:" Examining the Mental Health Byproducts of the Transfer Portal and NIL on Student-Athletes
Authors: Madden Ethan , O'Hallarn Brendan
Published: July 2024

Two rule changes have brought seismic changes to collegiate sports in the United States—the right for college athletes to monetize their Name, Image, and Likeness (NIL), and the Transfer Portal for athletes looking to switch schools. Qualitative interviews with 16 college athletes, explored the mental health byproducts of these new athlete opportunities. The interviews suggest that many athletes are hesitant to participate in NIL due to a lack of guidance. The study also found that college athletes believe entering the Transfer Portal to be a highly stressful experience, comparing the process to being recruited out of high school. However, the accessibility of the Transfer Portal also helps students leave situations that are negatively impacting their mental health faster and easier than before. Since college athletes are a highly at-risk demographic of college athletes for mental health issues, their first-hand perspective can help on-campus staff and administrators have a better understanding of what is needed to give collegiate athletes the best possible experience to learn and develop as students and citizens.
