Evaluation of health monitoring parameters for automotive pneumatic elastomeric system using soft pressure sensors for enhanced vehicle performance.
No full textIn the rapidly evolving automotive industry, the need for reliable and efficient pneumatic elastomeric components necessitates cutting-edge health monitoring methods, given that the pneumatic components are directly connected to dampening properties, ride comfort, vehicle safety, and stability. A novel approach for pneumatic elastomeric component health monitoring utilizing ionic liquid (IL)-based soft sensor technology has been proposed, which has the promise to enable real-time health monitoring and prognostics of vehicle systems. The proposed polymer sensor leverages the distinctive characteristics of flexibility, stretchability, and high sensitivity. These properties are critical for precisely measuring load, vertical displacement, air pressure, force locations, and load frequency of the air pressure responsive rubber part. The sensors are attached to three key contact positions: two on the metal cover of the elastomeric component and one on the piston of the component to provide critical information about the rolled and unrolled rubber. These sensors continuously measure essential parameters for health monitoring. The collected data can identify potential issues such as leaks, wear, or structural weaknesses. The finding illustrates the effectiveness of the IL-based soft sensors in providing precise and reliable data for health monitoring parameters
Canine Agility on the A-Frame Obstacle
No full textAgility dogs rely on speed, strength, and precision to safely complete obstacles, such as the A-frame. These athletes can experience injuries in training or competition and the variability in multiple repetitions is undocumented. The purpose of this study was to evaluate whether canine mass and trained contact behavior affected performance variables, including number of footfalls, obstacle completion time, and velocity between repetitions. Twenty-one actively competing dogs, at the masters level in American Kennel Club agility, were recorded completing two repetitions of the A-frame under standardized conditions. Paw placements were tracked manually frame by frame in XMALab and statistical analyses including mixed effect models and linear mixed models were performed in RStudio. Tukey post hoc tests from mixed effects models revealed no significant difference in the total number of footfalls (p = 0.8517), obstacle time (p = 0.0824), or velocity (p = 0.1064) between repetitions. Linear models demonstrated weak associations between mass and each performance variable across repetitions. Qualitative analysis of paw placement patterns were visualized through positional and duty factor (e.g., contact durations) graphs and demonstrated behavioral distinctions in dog performance including contact behavior. These findings suggest that A-frame performance may be more influenced by individual training, consistency, and coordination between dogs and handlers than by mass or contact strategy, as individuals showed stereotyped repetitions of the same obstacle. This research contributes to a growing understanding of canine biomechanics and highlights the importance of factors that are based in training to promote safety and reduce injury in canine athletes
Review of: Lily of Appalachia Series: \u3cem\u3eUnder the Bridge\u3c/em\u3e (2017), \u3cem\u3eUnder Fire\u3c/em\u3e (2018), and \u3cem\u3eUnder the Juniper Tree\u3c/em\u3e (2019)—Emily Steiner
Full text linkThe Lily of Appalachia series—the first series by Conservative Mennonite novelist Emily Steiner—is set in the Appalachian coal-mining country of Kentucky and West Virginia. The timeline follows Lily Burchett from schoolgirl to middle years, set in (as close as I could tell) the mid-1920s through the late 1930s. Taken together, the three books, Under the Bridge, Under Fire, and Under the Juniper Tree make a full circle, where the dreams and ambitions of the first book are not realized until the last book. If you read one of these books, you should read all of them. Each book title references a symbol that holds a theme throughout the book. The first, a bridge, which symbolizes a crossing over, is washed away. The second, a fire, which is a symbol of purification, is both a metaphorical fire of persecution and the literal fire of their house. The third, a Juniper tree, is undoubtedly a reference to the Biblical story of Elijah where deliverance is found in the midst of resignation. [First paragraph.
The Impact of Visiting Artists on Education
Full text linkThe purpose of this Honors Research Project was to provide an extensive resource for art educators who wish to incorporate meaningful experiential learning opportunities by bringing visiting artists into their classrooms. The first section is a brief literature review detailing the benefits of incorporating experiential learning and visiting artists in the classroom. Following the literature review are three appendices provided as resources for teachers to utilize. The first appendix pertains to Ohio-based illustrators being used as visiting artists in schools and includes a list of ten illustrators with respective profiles for each. The second appendix contains a bibliography of the artist profiles for teachers to find research and additional information on the illustrators. The final appendix is a 24-week sample course of instruction split into six units with projects and vocab based on the specific illustrators for educators to incorporate into classrooms as a project-based visiting artist experience
Making Their Mark: Women Judges on the U.S. Courts of Appeals
Full text linkWomen who reach the bench in the U.S. Courts of Appeals have endured the gauntlet of law school, legal practice, and Senate confirmation to secure their prestigious place in the federal judiciary. How do these exceptional individuals approach their role in shaping judicial policy—and how do their colleagues receive their work? In this paper, we will draw on findings from an original dataset of published decisions from 2009-2016 that suggests that women judges invest more time and effort in crafting majority opinions than their male counterparts, but that this investment has a comparatively lower yield in influencing the development of legal policy outside their circuit. These findings have implications for organizational culture within a court, the development of new technologies, and socializing law clerks into the professio
The Myth of the Fourteenth Amendment and the Civil Rights Act of 1866
Full text linkAlthough legal scholars who focus on the original meaning of the Fourteenth Amendment disagree about many things, almost all agree that John Bingham proposed what was to become Section One of the amendment in order to definitively establish the constitutionality of the Civil Rights Act of 1866. In fact, however, the Joint Committee on Reconstruction chose to insert the Bingham formulation in place of a provision that would have explicitly constitutionalized the Civil Rights Act. This Essay describes the circumstances that provided the backdrop for the consideration of the Bingham proposal and the implications that this context has for our understanding of the original meaning of Section One
Migration, Trauma, and \u3cem\u3eTweeback\u3c/em\u3e: Perspectives on Russian Mennonite Identity in Elina Penner’s Novel \u3cem\u3eNachtbeeren\u3c/em\u3e
Full text linkAfter the dissolution of the Soviet Union in the 1990s, a group of about 2.5 million Russia Germans immigrated to Germany, benefiting from the German law that recognizes citizenship to ethnic Germans who arrived in the territory as late ethnic Germans resettlers. Including their children, this subset of Germany’s population now numbers about 3.5 million, and about 350.000 Russia Germans have a Mennonite background. Of the 500.000 Plautdietsch-speaking people worldwide, about 200,000 of them live in Germany. In her debut novel, Nachtbeeren, the author Elina Penner illuminates the everyday life of German Mennonites from the Soviet Union and the successor states. This article explores the novel’s portrayal of elements that impact the hybrid cultural identity of Mennonites from the former Soviet Union in the context of their lived experience in Germany. It contextualizes Penner’s novel within the corpus of literature written by German authors with origins in the Soviet Union and discusses the key experience of migration and the historical dimension of relocation, displacement, and exodus in the Mennonite community.

Rapid Convective Quench Apparatus Design
Full text linkIn this project, we will research, model, and simulate the heat transfer of a red-hot steel plate undergoing a rapid quenching process by high pressure water jets. Our objective is to quench the steel plate in such a way so that the steam formed from the initial water contact does not inhibit the oncoming water from making proper contact with the plate. After sufficient research has been done, we will design an apparatus which will perform the optimal quenching method and record temperature data with the goal of obtaining the heat transfer coefficient. The purpose of our project is to design and verify a method of rapid cooling that is cheaper and more efficient than other existing methods of quenching while still achieving the same material properties such as hardness
Time Series Modeling of Akron Air Quality Index (AQI) Data
Full text linkWith the increase in population and industrialization around the world, climate has become a major concern for many researchers. One measure that has drawn much interest is air quality. There are available resources that track the Air Quality Index (AQI) in most large cities, but there is a general lack of information regarding Air Quality forecasts, even for one day in the future. This project aims to find a useful statistical model for representing and predicting the AQI measure in Akron, Ohio over time. By using historical air quality data from the United States Environmental Protection Agency and AQI.in, an international air quality tracking website, a time series ARIMA model for air quality was developed for prediction. Given the information of the day prior, this model provides a good way to estimate the AQI of the next day. This proposed model can be used to predict potential spikes in AQI that may be dangerous for vulnerable individuals. Future research may aim to find more accurate models so people can be more aware and prepared for the quality of their air tomorrow and beyond
Effects of diet composition on physical parameters in Danio rerio
Full text linkWith the use of zebrafish as a common model organism for human health, the reduction of confounding variables in their care is key. Many commercialized zebrafish diets are available for purchase, but each one consists of a different ratio of these crucial macronutrients. This study aimed to determine the effects long-term diets high in one macronutrient would have on the morphometrics, heart, liver, and protein content of zebrafish. Four diets were fed over a period of almost two years- high lipid, high carb, high protein, and a control diet. The control diet was the standard feed used in this lab, GEMMA Micro 300. Image analysis and dissection were performed on the zebrafish carcasses to obtain morphological measurements and heart and liver masses. The carcasses were then homogenized for a Bradford assay which allowed for the calculation of the protein content. The results showed a high carb diet resulted in a significantly lower body mass and reduced morphometrics than the other diets, possibly indicating an induction of type II diabetes. The control diet appeared to result in the largest morphometrics, with the high protein and high lipid diets measuring in the middle. Because the high protein diet did not produce a significant difference in protein content, additional studies are needed to ensure the absorption of the protein
