Improving the Peak Performance Lifespan of a Two-Piece Composite Bat
Get PDFThe push for innovation and enhancement of sports equipment in recent years has led to significant advancements in composite materials. This project aims to propose new design possibilities that will improve the lifespan of a two-piece composite bat. Using finite element analysis (FEA) software, various fiber orientations and materials were modeled and analyzed for their impact response. Two unique quarter-cylinder designs along with a baseline design were modeled with symmetric boundary conditions. The proposed bat deigns include a helicoidal model and a CFRP-Aramid hybrid model. Comparative analysis of the elastic responses revealed that both the helicoidal and hybrid models demonstrated higher internal energy when contrasted with the baseline model. This heightened internal energy signifies improved capabilities in mitigating stress, strain, fatigue, and damage accumulation over time. Furthermore, the increased displacement observed in the helicoidal and hybrid models suggests superior flexibility and energy storage during impact, therefore aiding in the distribution of forces across the structure and reducing localized damage. These findings underscore the potential of innovative composite bat designs to further revolutionize sports equipment and provide a competitive edge by maximizing durability within the industry standards
Materials Testing for Large Format 3D Printing
Get PDFAn ABS Carbon Fiber blend was printed into single walled hexagons at a variety of settings on a Cincinnati BAAM large format 3D printer. These hexagons were then cut down into sheets and had tensile and flexural test samples cut out of them, in order for materials testing to be performed. Tensile strength, tensile strain, young’s modulus, flexural strength, deflection and elastic modulus were all determined. A desktop CNC machine and a planer were purchased for the manufacturing of these samples, and an efficient cutting procedure was designed and optimized. After all data collection concluded, this data was thoroughly analyzed, furthering Additive Engineering Solutions’ understanding of the materials they print with, and how certain print settings affect those materials
A Review of Transposable Elements in Crustaceans
Get PDFThis project centers around transposable elements (TEs), specifically those found in crustacean species. While transposable elements have been a growing area of interest in the scientific community for some time, the information surrounding the present state of TEs in the field of crustacean biology is limited. This project seeks to shed light on this area of study. It will focus on the relationship between TEs and crustacean evolution, and TE prevalence in crustaceans. TE studies will be categorized by these general themes as well as crustacean taxa. It will seek to answer the research question: What is known about the evolutionary relationship between transposable elements and crustaceans? Additionally, what research currently exists surrounding transposable elements in crustaceans regarding the prevalence of transposable elements in crustaceans

Archiving the Ephemeral in Digital Public Space: Using Speculative Design to Consider Collaborative Fan Play in the Metaverse
Get PDFLooking at fan activity through the lens of play, this paper considers the archiving opportunities and challenges posed by new technology for playful ephemeral fan co-creation in multiplatform digital contexts. These include technical concerns such as platform fragility and how to capture inherent liveness and temporality, but also ethical concerns such as sustainability, consent and content moderation.
To examine this, the paper takes fan-created alternate reality games (ARGs) as a particular example of such archiving challenges. It first describes a real example of such a game, ‘Blow the Man Down’ before introducing speculative design as a method to consider a potential future where emerging technologies such as the metaverse and artificial intelligence form part of online collaborative play and how it is archived.
A speculative design scenario is presented where players can choose to recreate the experience of initial interactive play either as a dream-like replaying of the original player choices, or as a branching experience where a new story and experience is created each time; an ever evolving and updating archontic text. In such a context we can then consider, is archiving possible, or even desirable
Assessing CO2 Capture on Amine Sorbents at Low Vacuum Swing Conditions
Get PDFCarbon dioxide (CO2) emissions to Earth\u27s atmosphere have increased rapidly in recent decades largely due to growing fossil fuel use in human-led activities The research contained in this proposal assesses a way to capture CO2 concentration in the atmosphere. The project studies the effectiveness of a vacuum swing adsorption (VSA) process for capture of CO2 from air. CO2 will first be adsorbed by introducing an amine sorbent to a CO2-rich environment for a predetermined period. The amine sorbent will be placed in a VSA unit that will operate at the desorption stage. The sorbent will then be sent to a second VSA unit that will be operated under a vacuum to produce the desorption stage. This research will provide insight to a low-energy CO2 capture process that uses low regeneration-energy sorbents and efficient vacuum processes. Once an optimal setup for capture and desorption are determined, industrial feasibility will be considered via an economic analysis. This project is a joint project and will be completed by Brock Haas ([email protected]) and Payton Taylor ([email protected]). Brock\u27s specific role in this project is the preparation and optimization of high density, low energy CO2 sorbents and analyzing the experimental data. Payton will be responsible for the creation of the VSA units and also analyzing the data from the experimental trials
Morality vs. Mortality: The Ethics of Physician-Assisted Death in the United States
Get PDFAccording to the American Academy of Hospice and Palliative Medicine, physician-assisted death is defined as a physician providing, at the patient’s request, a prescription for a lethal dose of medication that the patient can self-administer by ingestion, with the explicit intention of ending life. This paper will examine the different perspectives on the prevalent issue revolving around the ethics and criminality of physician-assisted death and euthanasia in the medical field – a heavily debated topic since the concept was conceived. It will explore the history and controversy revolving around the practice using ethical, faith-based, and scientific perspectives relating respectively to the ideas of death with dignity, autonomy, vitality, and the sacredness of life as well as taking the criminal aspect of it into consideration. In order to understand the correlation between political, religious, and social beliefs and the support for the legalization of physician-assisted death, this paper will explore and analyze Gallup’s 2018 Values and Beliefs poll regarding physician-assisted death and public opinion. The ultimate goal of this research paper is to allow the reader to become more informed on the topic of physician-assisted death and to shed light on the differing perspectives regarding the controversial subject
Wetting Transition of 3D-printed Surface Features
Get PDFThis project aims to build on the previous research of prior students in the study of the wetting transition of a textured, 3D-printed surface. The surfaces studied will be constructed by a resin printer in the lab and will be composed of an array of uniform, microscopic pillars. Features of the textured surface, such as pillar diameter, pillar spacing, and pillar height, will be varied to study the impact on the wetting transition of water, oil, and a combination of water and oil. The wetting transition is defined as a transition from a state where the surface cavities are occupied by air to a state where the surface cavities are occupied by the liquid. Optical microscopy will be used to observe the surface as well as measure the time for the wetting transition to occur. The data collected will be used to create educational material that will compile the data collected from this project, as well as the projects of prior students
The Effects of Static Versus Dynamic Stretching on Lower Extremity Power Output and Flexibility in Dancers
Get PDFCollegiate dancers require a large range of motion throughout all joints for performance success. Previous research has shown static (STA) stretching to be most effective at improving flexibility (Chaabene et al. 2019), due to this factor, warmups for dance are primarily based on STA stretching to allow dancers to reach their maximum flexibility. Previous research has also shown that STA stretching before activity can have negative effects on an athlete’s power output, and a large amount of power is essential for dance. PURPOSE: Determine the effect of STA and dynamic (DYN) stretching on lower extremity power and flexibility in collegiate dancers. METHODS: Subjects (N=10) were recruited from The University of Akron Dance Team. Data collection involved 3 conditions with different stretching protocols. DYN warm-up, STA warm-up, or no warm-up (CON) were completed before each independent condition of data collection. Biodex testing was performed to assess individual power output of right and left knee extension and flexion and a flexibility test was performed to test hamstring flexibility. Paired t-tests were used to assess significance. Significance was set at p\u3c 0.05. RESULTS: Significance (pCONCLUSION: There was a functional difference in lower extremity power output for all power measures, but only some to a statistically significant level. Previous research has demonstrated similar power output results in dancers following DYN vs. STA warmups where no significant difference was observed (Vlieg et al., 2019). The results contradicted previous research which resulted in a significant increase of flexibility from DYN versus STA stretching in dancers (D’Elia et al., 2023). Future research should analyze flexibility and power output in dancers after being accustomed to dynamic warmups for a longer period, should analyze a different group of athletes, and analyze results after performing warmups of equal length
