Carbon emissions have become a major concern since the turn of the century. This has increased the demand of hybrid vehicles in United States market. Hence, there is a need to make these vehicles more efficient. This thesis focuses on creating a thermal model that could be used for optimization of these vehicles. The project was accomplished in collaboration with EcoCar3, and the temperature data obtained from the model was compared with the experimental temperature data gathered from EcoCar's testing of the vehicle they built. The data obtained through this study demonstrates that the model was accurately able to predict thermal behavior of the electric motor and the high-voltage batteries in the vehicle. Therefore, this model could be used for optimization of the powertrain in a hybrid vehicle.

This study analyzes mechanical properties of additively manufactured plastic materials produced in a conventional 3D printer. This topic has generally been studied in controlled scenarios, and this study aims to reflect the properties seen by consumers. Layered prints are inherently anisotropic due to the direction of the layers and associated weaknesses or stress concentrators. Thus, the ultimate strength and elastic modulus of plastic specimens produced using default settings are compared based on print orientation angle, and trends are observed. When a specimen is parallel to the build plate, it tends to have ultimate strength and elastic modulus near the published bulk values of 13.2MPa and 404-710MPa, but these values tend to decrease as the print angle increases.

The project consists of steps that a Formula SAE team could take into developing their first carbon fiber monocoque chassis. The project is based on an interview with a successful team that has build carbon monocoques for the last several years. The project covers the steps into designing a carbon monocoque, including aspects that need to be highlighted in the design process as well as an outline of the overall rules and regulations regarding carbon fiber monocoques. The project also encompasses simple finite element analysis procedure that would introduce teams into carbon fiber composite sandwich analysis and its applications in racecar monocoques. The project also includes steps in manufacturing a carbon fiber monocoque beginning from methods to acquire necessary materials to the final process of de-molding the monocoque. The method has been used before from several FSAE teams, proving its viability. The goal is that through this report, teams could have an idea of where to start in developing their carbon monocoques and have a clear path to take on going from initial designs up until a final finished product.

In today’s day and age, the use of automated technology is becoming increasingly prevalent. Throughout the aerospace industry, we see the use of automated systems in manufacturing, testing, and, progressively, in design. This thesis focuses on the idea of automated structural design that can be directly coupled with parametric Computer-Aided Drafting (CAD) and used to support aircraft conceptual design. This idea has been around for many years; however, with the advancement of CAD technology, it is becoming more realistic. Having the ability to input design parameters, analyze the structure, and produce a basic CAD model not only saves time in the design process but provides an excellent platform to communicate ideas. The user has the ability to change parameters and quickly determine the effect on the structure. Coupling this idea with automated parametric CAD provides visual verification and a platform to export into Finite Element Analysis (FEA) for further verification.

Following the Global Financial Crisis of 2007-2008, financial institutions faced regulatory changes due to inherent weaknesses that were exposed by the recession. Within the United States, regulation came via the passing of the Dodd-Frank Wall Street Reform and Consumer Protection Act in 2010, which was heavily influenced by the internationally focused Basel III accord. A key component to both of these sets of regulations focused on raising the capital requirements for financial institutions, as well as creating capital buffers to help protect solvency during economic downturns in the future. The goal of this study is to evaluate the effectiveness of these changes to capital requirements, and to hypothesize as to what would happen if the modern banking system experienced the COVID-19 pandemic recession with the capital and leverage levels of the banking institutions circa 2007. To accomplish this, data from the Federal Reserve describing the capital and leverage ratios of the banking industry will be evaluated during both the Global Financial Crisis of 2007-2008, as well as during the COVID-19 Recession. Specifically, we will look at by how much capital was improved due to Dodd-Frank/Basel III, the resiliency of the capital and leverage ratios during the modern COVID-19 recession, and we will look at the average drop in capital levels caused by the COVID-19 recession and apply these percentage changes to the leverage/capital levels seen in 2007. Given the results, it is clear to see that the change in capital requirements along with the counter-cyclical buffers described in Dodd-Frank and Basel III allowed the banking system to function throughout the COVID recession without approaching insolvency in the slightest, something that ailed many large banks and firms during the Global Financial Crisis. As an answer to our hypothetical, we found that the drop seen affecting the measures of bank capital experienced during the COVID pandemic when applied to values seen at the beginning of the 2007 recession still led to a well-capitalized banking industry as a whole, highlighting the resiliency seen during the COVID recession thanks to the capital buffers put in place, as well as the direct assistance provided by the federal government (via PPP loans and stimulus checks) and the Federal Reserve in keeping the hit on capital to minimal values throughout the pandemic.

What if I told you that a few photos of a sweatshirt, delivered at the perfect time, cracked a case that had stumped some of the world’s greatest marketing minds for more than twenty years? What if I told you that a dismissed lawsuit played an integral part in this? One made possible by a rainy night in Couva, Trinidad? Or that all of this, hundreds of years in the making, could aid a wrongfully incarcerated man in being freed after spending twenty two years in prison, and pioneer one of the largest-scale social justice movements of the 21st century? All catalyzed by the effects of a global pandemic? If I told you, would you believe me? But let’s get back to that sweatshirt for now.<br/>In January 2020, the Coronavirus was a seemingly distant issue for another part of the world to most Americans. A generation that had seen the likes of H1N1 and Ebola come, cause irrational panic, and subsequently disappear had grown complacent with regard to unknown diseases. On March 9th, Utah Jazz center Rudy Gobert took a defiant step in dispelling fears of COVID-19 by touching every microphone in the room at the end of an interview. Two days later, a test revealed that he had contracted the virus, the first professional athlete to do so. The NBA suspended all activities, and thus began the succession of sports leagues across the nation suspending their seasons as global infection numbers rose. But we humans are resilient. As weeks became months, the NBA and WNBA were able to engineer “bubbles” to play in: isolated areas with only the players and essential personnel to play the games, equipped with safety precautions and persistent testing. With no fans allowed inside, social media and media members provided the only glimpse into the “bubble” that ordairy fans would get.<br/>The mornings of July 25th and 26th, as the players arrived for the first games of the day and were snapped by photographers, many sported orange hoodies with the trademark white WNBA logo in the center, to promote the start of the WNBA’s “bubble” season that summer. This sent the internet into a frenzy. “#OrangeHoodie” was trending across all social media platforms, the item sold out on many websites, and more people than ever were talking about the WNBA online. That season, WNBA viewership spiked. More people watched the WNBA than ever before, even with the NBA’s playoffs taking place at the same time. How, then, did a single orange hoodie change the future of marketing the WNBA? What does that tell us about other women’s sports that have similarly struggled with attention and viewership? What role does media exposure play in all of this; do we perceive women differently in the media than we do men? Are these issues rooted in deeper societal prejudices, or are women’s sports simply quantifiably less entertaining?<br/>On a journey to find the answers to these questions, I learned a lot about the relationship of media and culture, about sport, and about the outstanding untold stories of American sportswomen. However, the most important thing I found was that women are marketable. After long being denied the opportunities and exposure they deserve, American culture has as a result pushed women to the background under the guise of them not being demanded or marketable. This could not be further from the truth. They are not demanded because they are not seen. Investing in sportswomen would not only create a better future for all women, but for all people. How, then, is this achievable? How will the powers that be allow for changes to be made? How can we as individuals be receptive to this change? In this thesis, I will take you on a journey where media is fun and fair, and where the future is female.

In the 21st century economy, life moves pretty fast, and change is happening all around us. For example, it was common to drive to shopping malls with your friends or family and spend the whole afternoon browsing through hundreds of items until you found the perfect purchase. Or, only a few months ago, the entire world was put on lockdown to stop the spread of COVID-19, which caused a recession when consumers stopped spending as much to start saving. Americans also used to enjoy their loud, gas-guzzling cars and trucks to get them from place to place. Now what changed, and why? The study of economics justifies how we, as human, fundamentally live and make choices every day. As we notice the results of our choices, we may continue to do the same the next day, temporarily go another route, or alter our behavior permanently. This framework presents the concept of innovation. By applying this logic to the business world, I will attempt to analyze and defend why the innovations of e-commerce, COVID-19 vaccines, and electric vehicles were the natural cause of society changing perspective to move forward toward a better tomorrow.

Math homework is a highly debated topic within the middle school education field. Teachers, parents, and students all have differing opinions on what the ideal math homework assignment is and how it promotes academic achievement. This study was intended for discovering what the optimal middle school math homework assignment looks like, how teachers can best follow-up on the assignment, and the most beneficial quantity and frequency of homework. Currently, teachers need more distinct guidelines when designing homework assignments. Students in Barrett, The Honors College, at Arizona State University were asked a series of questions about the type, length, and follow-up practices of their homework assignments and how they felt about them. It was found that students who like math are generally highly motivated in the subject. Most often, students are given short but frequent practice homework assignments, which they find to be most helpful, and they appreciate when teachers review the steps and solutions to the assignments in class. These results should allow educators to better align their math homework assignments with practices that students find to be helpful and necessary.

This thesis will discuss how procurement should approach price increases from suppliers during at time of rising inflation. It explains the process that should be taken by a procurement associate and the different routes. The thesis mainly focuses on how procurement needs to be adaptable to changes during inflation since it can cause many aspects of the business to be volatile. This paper also leaves room for future research to analyze the optimal time to negotiate with a supplier after a downward trend.
