Design of an Active-Control Pressure Regulator for a Rocket
Full text linkAn electronically actuated pressure-regulation valve and controller are necessary for maintaining pressure levels in a pressure-fed liquid-fueled rocket engine. Mechanical regulators are too heavy and have unacceptably high-pressure variation throughout the operation of a dynamic system like a rocket. Developing an electronic pressure regulator using a PID controller is a method by which a reliable, accurate, and lightweight flow regulator can be built for use on a rocket vehicle. This work will outline the development of flow simulations, PID controller, physical valve hardware, and initial testing
Rhamnolipid as an Effective SRB Biocide – Determining a Solution to Replicate Anticipated Conditions
Full text linkThis project aimed to develop a laboratory-scale solution that replicates produced water conditions (CO2 + brine) found in crude pipelines, with the added requirement of promoting the growth of sulfate-reducing bacteria (SRB). A previously successful study was used as a reference, which employed a hybrid salt solution containing essential nutrients and environmental factors. The proposed solution included 10 g sodium chloride, 1 g sodium pyruvate, 0.2 g ammonium chloride, and 0.8 g sodium sulfate per liter of deionized water. Electrochemical testing (Linear Polarization Resistance and Electrochemical Impedance Spectroscopy) was performed on solutions with and without rhamnolipid. Results from the non-rhamnolipid solution were comparable to published data, suggesting the added nutrient additions to the produced water simulant had minimal impact on corrosion behavior. If SRB growth is confirmed, this solution could serve as a practical model for studying SRB-induced corrosion in crude pipeline environments
Analysis of Sled Dog Biomechanics
Full text linkThis paper is an analysis of data collected by Dr Rachel Olson and her team. The data was collected from the same set of sled dogs before and after training for the Iditarod race. The goal of this paper is to draw conclusions on whether the gait of sled dogs’ change with fitness level. The data was cleaned in R to find the average peak for forelimb joint angles per run for each dog. The data was analyzed with 3 different ANOVAs – one including both the shoulder and carpus, one for just the shoulder, and one for just the carpus. From these ANOVA’s it was determined that the fitness of the dog does change gait biomechanics. The peak maximum carpus angle increased whereas the peak maximum shoulder angle decreased with increased fitness
Automatic Hole Saw Testing for MK Morse
Full text linkM.K. Morse has a hole saw tester they use for their hole saw product line. The tester currently requires constant operator attention for a process that could be automated. The goal of this project is to create a new hole saw tester that can run without the need for an operator\u27s complete attention and give reliable data for the hole saws
Effects of Exercise on Cognitive Performance
Full text linkThis research project “Effects of Exercise on Cognitive Performance” will be conducted with the purpose of determining the relationship between exercise and cognitive performance. The relationship between injury and cognitive performance will also be investigated. In order to investigate these relationships 60 participants who are current students at the University of Akron will be asked to complete three cognitive assessments, one while at rest, one while riding an exercise bike, and one following the completion of exercise. The results of these three assessments will be compared to determine the relationship between cognitive performance in all three states. Participants will include both males and females as well as division 1 athletes and non-athletes to provide a diverse participant population and ensure that all types of injuries are represented throughout the study
Software Literacy in Construction
Full text linkThe construction industry increasingly relies on software like Bluebeam Revu for their quantity takeoff, document management, and collaboration needs. This project will outline pertinent information obtained through their Bluebeam professional training program and reflect it with a detailed estimate of a real life construct project
How Do Religious Beliefs, Practices, and Experiences Impact Mental Health?
Full text linkThe following literature review discusses the influence religious practices, beliefs, and experiences impact mental health. The discussion will revolve around three main religions: Catholocism, Judaism, and other denominations of Christianity. Negative and positive influences of religion on mental health were found and discussed
Are you smarter than a dancer?: An investigation of physical agility and cognitive ability between dancers and non-dancers.
Full text linkThe purpose of this study is to develop a better understanding of learning and memory in dancers in comparison to non-dancers. I plan to search further into the way formally trained dancers perform on certain tests in comparison to people with no dance training. This will be measured through a series of five tests completed in the following order: the sit to stand test, hop and stop test, the single leg stance test, the digit symbol substitution test, and a tower of Hanoi task. These tests will be conducted on 20 dance majors, and 20 non-dance students. This data will be analyzed through a regression with all five of these predictors using logistic regression. Through this method, we will try to predict group membership. This method will allow us to compare and contrast the physical and cognitive abilities of dancers to non-dancers. I predict that we will see a significant difference between the two groups, with dancers scoring better on all five tests than non-dancers
