Llnl Raft Flash Pole Redesign, Jack Stangel, Evan Wolfson, Jake Borden, Alexander Meeter

Mechanical Engineering

During research exercises in the ocean, Lawrence Livermore deploys a fleet of rafts outfitted with flash modules affixed to tall poles (in tandem called flash poles) that flash while a photo is taken to act as datums for data collection. The current flash pole design that the LIDSS (Lawrence Livermore Independent Diagnostic Scoring System) team uses is too short to be visible in high seas, not mechanically suited to be made taller, too susceptible to the elements and blunt impact and too difficult to service. We aim to solve these issues.

Torsional Vibration Kit Simulator (Tks), Joseph Thachet, Luca Lawson, Ryan Ota, Otis Mcloughlin

Mechanical Engineering

The goal of this project was to create torsional vibration on a shaft while limiting axial and radial vibration. To do this an eddy current brake was used to slow down a rotating shaft. The electromagnets used to create the eddy currents are able to be turned on and off at a frequency produced by a function generator. This power cycling of the electromagnets creates an alternating braking force thereby inducing torsional vibration while limiting the other two vibration types

Uv Vessel Hoist Scope Of Work, Quinn J. Horak, Harvey Perkins, Andrew A. Osborn, Mikayla H. Nieman

Mechanical Engineering

The San Luis Obispo Wastewater Treatment Plant uses ultraviolet (UV) tubes to purify water. These tubes are cleaned by an internal wiping mechanism that must be removed for servicing and replacing damaged tubes. Currently, this is accomplished by using an engine hoist, but this method requires a large amount of effort and is not safe. Technicians have requested a new method of lifting wiper mechanisms that is safer, faster, and easier to use than their current method.

To solve this problem, we have developed a design that consists of a custom gantry crane with a hoist on a trolley. The …

Trailer Transport System For Multi-Ton Bins, Joanna Lizbeth Bendy, Kevin Matthew Creel, Annelise Vaara Cuneo, Hugo Alonso Valdez

Mechanical Engineering

This project aimed to improve the process of transporting 10,000-pound industrial waste bins. The current method for relocating these bins poses safety risks and requires significant manual effort.

Brush Seal Cycling Test Rig, Angelo J. Reis, Neil M. Bedagkar, Max A. Soury, Eoin K. Lenham

Mechanical Engineering

To prevent backflow from the high pressure compressor stages of their gas turbines to lower pressure regions, Solar Turbines utilizes brush seals along their driveshafts. Due to manufacturing limitations, no shaft is perfectly symmetric about its rotating axis, leading to orbiting that creates asymmetric friction on the shaft through rubbing. With this biased application of friction comes a hotspot on one side of the shaft, causing bowing of the shaft and cascading into an amplified vibrational response. Our goal is to gather data on this phenomenon and offer a potential solution.

Micro Mobile Home R3, Roha Y. Ali, Yuka M. Iwashita, Luke C. Douglas, Joshua Q. Le

Mechanical Engineering

Homelessness is an ever-growing issue all around the world. In 2023, over 250,000 or ~40% of all people experiencing homelessness did not have access to shelter spaces in the U.S. [1]. All people have the right to a place where they are safe from violence, crime, and the constant fear that they will be forced out.

Both homeless people and outdoor enthusiasts need a new way to keep themselves and their belongings safe when living outdoors, since existing products do not offer adequate security, portability, or versatility.

Anything No Longer Goes: How The Eleventh Circuit Has Settled On One Standard To Determine Deliberate-Indifference Claims, Sarah Beth Scarborough

Mercer Law Review

Deliberate indifference to the medical care of a loved one, or oneself, rightly causes outrage. When such an occurrence takes place behind prison walls, inmates or loved ones on their behalf, file a deliberate indifference claim under 42 U.S.C. § 1983,and they allege a violation of their Eighth Amendment right to be free of cruel and unusual punishment. However, the test for deliberate indifference has been misconstrued and misapplied for decades within the United States Court of Appeals for the Eleventh Circuit. Such a malleable test leads to different standards of proof for a plaintiff to meet, and confusion among …

Repugnant Verdicts For $1000: Navigating The Intersection Of Double Jeopardy And Conflicting Verdicts In Mcelrath V. Georgia, Talia Levine

Mercer Law Review

“No man is to be brought into jeopardy of his life, more than once, for the same offense.” This ancient maxim, preserved in the Double Jeopardy Clause of the Fifth Amendment, is a hallmark of the American justice system. The Double Jeopardy Clause gives a criminal defendant the constitutional right not to be tried again for the same offense after being acquitted. This guarantee stands as “[p]erhaps the most fundamental rule in the history of double jeopardy jurisprudence.”

The Supreme Court of the United States has repeatedly upheld these principles; by refusing to allow retrial following an acquittal, the Court …
