Experimental Impacts into Sloped Targets
Get PDFAsymmetric craters have been ob-served on sloped surfaces on the Moon [1] and extensively across Vesta [2] and Ceres [3]. For example, Lowell Crater (Fig. 1A) is a large crater on the surface of the Moon that has a small-er crater, Lowell H, which formed when an asteroid impacted the sloped surface of Lowell’s crater rim [1]. The topography map of Lowell H (Fig. 1B) shows the original sloped crater wall, the highly asymmetric and slumped Lowell H crater, and the debris flows that formed during its collapse.
Typically, impact cratering experiments are performed into smooth, flat-lying targets as a way to simplify the process. In the last decade, [4&5] have performed low-speed impacts into sloped targets. Here, we have used the Vertical Impact Facility (VIF) at NASA Johnson Space Center to fire 4.76-mm aluminum spheres at speeds of 1.5 km/s (3400 mph) into 0.4-0.8 mm rounded, sieved sand targets that were built to have slopes of 0°, 5°, 10°, 15°, and 20° above horizontal

NerveX
Get PDFThe NerveX fidget toy is a modern and stylish alternative to traditional fidget toys, designed especially for adults. Many fidget toys are made for children, which can make them feel out of place in professional or social settings. NerveX solves this problem by offering a discreet and effective way to manage stress, anxiety, and conditions like ADHD and OCD.
One of the key features of NerveX is its smooth, endless spinning motion. This repetitive movement helps people with ADHD stay focused and engaged in tasks. It can also provide comfort for individuals with OCD by giving them a calming action to manage compulsive behaviors. The spinning motion is simple yet effective, helping to reduce stress and improve concentration without being distracting to others.
To make sure NerveX meets the needs of its users, I conducted research and gathered feedback from adults aged 20 to 28. This helped shape the final design to be both functional and appealing. The feedback highlighted the importance of a high-quality fidget toy that is durable, effective, and comfortable to use in daily life.
NerveX is made using 3D printing with two different materials to ensure durability and performance. The spinning band is made from TPU, a flexible and long-lasting material that allows smooth motion without wearing out quickly. The outer frame is made from PLA, a sturdy material that gives the toy structure and strength. This combination makes NerveX both reliable and long-lasting. The 3D printing process also makes it easy to produce in larger quantities, keeping costs low and ensuring accessibility for more people.
As I work towards completing the project, I am focusing on finalizing the design, improving production, and getting ready for distribution. To track progress, I will compare my estimated costs with actual expenses to make sure the project stays within budget. I will also monitor sales to understand how well NerveX is performing in the market. This will help determine if any improvements are needed to increase its success.
NerveX is more than just a fidget toy it is a practical and stylish tool designed to help adults stay focused and reduce stress. With its smooth spinning motion, strong materials, and discreet design, it provides an effective way for people to manage anxiety and improve concentration in their daily lives
Panel Impact and Compressing Strength Testing
Get PDFIntro/Purpose: This project was conducted to investigate how a material\u27s compressive strength is affected after being impacted while supported on three sides. This has broader implications, helping us understand how military equipment, such as battleships, have their compressive strength affected when impacted by projectiles like bullets, shrapnel, or other objects.
Methodology: This test was conducted using panels made of multiple layers of fiberglass pressed together to form a solid sheet. We then cut these sheets into multiple panels. These panels were rectangular, with a tab coming off three sides. The three tabs simulated a wall supporting the material around it. We developed five groups, with three panels per group. We then impacted the center of the panels with varying levels of force for each group. Afterward, we documented the damage and tested the compressive strength. Once this was completed, we collected all our data to analyze the relationship between impact force and compressive strength.
Results/Findings: From this, we expect to find that the impact on the panels reduces their compressive strength. Each group had different levels of damage based on the amount of force taken from the impact. The panels subjected to a greater impact force are expected to have the least compressive strength. This is because greater amounts of force lead to more cracks and structural defects, lowering the compressive strength. This information will help us understand the relationship between how impact affects compressive strength

Cybersecurity and Education: Terminology Defined and Contextualized for Educational Practitioners
Get PDFSchools have never processed, stored, and protected more student, faculty, staff, and stakeholder data, leading to a rise in big data analytics in the field of education. However, along with implications for data use and governance, there are practical implications of the cybersecurity of that data, including whether educational organizations possess equitable human, financial, and technological resources to ensure the cybersecurity of their websites, through which countless transfers of data occur every second. As a result, this strategic brief distills the NIST Computer Security Resource Center glossary from 9,787 terms (NIST, 2024a) to the 17 most critical terms for educational practitioners to comprehend in order to better understand the concept of cybersecurity and how it may impact their everyday work
