Barrett, The Honors College Thesis/Creative Project Collection
Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.
Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.
In order to best approach the paradoxical concepts of exonerations and wrongful convictions in the determinate system of US courts, both court agents (i.e. attorneys and judges) and citizens that interact with it must increase their understanding of the various perspectives found in the process. Through the use of an app for mobile devices, information from the perspective of these court agents can be easily accessible for anyone, serving as a valuable learning tool for not only individuals that strive to work in the justice system, but citizens that will possibly interact with it in the future as well.
The scope of this project is a combination of material science engineering and mechanical engineering. Overall, the main goal of this project is to develop a lightweight concrete that maintains its original strength profile. Initial research has shown that a plastic-concrete composite could create a more lightweight concrete than that made using the typical gravel aggregate for concrete, while still maintaining the physical strength that concrete is known for. This will be accomplished by varying the amount of plastic in the aggregate. If successful, this project would allow concrete to be used in applications it would typically not be suitable for.<br/>After testing the strength of the concrete specimens with varying fills of plastic aggregate it was determined that the control group experienced an average peak stress of 2089 psi, the 16.67% plastic group experienced an average peak stress of 2649 psi, the 33.3% plastic group experienced an average peak stress of 1852 psi, and the 50% plastic group experienced an average stress of 924.5 psi. The average time to reach the peak stress was found to be 12 minutes and 24 seconds in the control group, 15 minutes and 34 seconds in the 16.7% plastic group, 9 minutes and 45 seconds in the 33.3% plastic group, and 10 minutes and 58 seconds in the 50% plastic group. Taking the average of the normalized weights of the cylindrical samples it was determined that the control group weighed 14.773 oz/in, the 16.7% plastic group weighed 15 oz/in, the 33.3% plastic group weighed 14.573 oz/in, and the 50% plastic group weighed 12.959 oz/in. Based on these results it can be concluded that a small addition of plastic aggregate can be beneficial in creating a lighter, stronger concrete. The results show that a 16.7% fill ratio of plastic to rock aggregate can increase the failure time and the peak strength of a composite concrete. Overall, the experiment was successful in analyzing the effects of recycled plastic aggregate in composite concrete. <br/>Some possible future studies related to this subject material are adding aluminum to the concrete, having better molds, looking for the right consistency in each mixture, mixing for each mold individually, and performing other tests on the samples.

The Arizona Civic Education Project is a cross-college collaboration supported by the Maricopa County Community College District to design, develop, and distribute publicly available, interactive, and engaging multimedia modules about Arizona State Government and the justice system. The modules aim to consist of high quality, professionally produced, value- neutral, fact-based, and bias-free videos, lesson plans, printable materials and activities that explain how Arizona state government is structured and how the justice system works in Arizona. The modules also identify and teach the audience how to deal with encounters within the justice system through lessons about the courts and dealing with the police. In addition to the resources we create, links are provided with attribution to other free resources that have been developed by other organizations. The targeted audience for this project is high school and college students attending public high schools and community colleges. In 2015, Arizona legislature passed the American Civics Act (House Bill 2064). This bill requires students to pass a civics test based on the United States Immigration and Naturalization civics questions. Students are required to score 60% or higher in order to graduate from high school or obtain a high school equivalency certificate. The Arizona Department of Education along with help from the Maricopa County Education Service Agency and Arizona educators have developed a mostly multiple-choice version of the required test. The modules provide helpful information that pertains to the civic test along with additional informational useful to students and educators alike.<br/>There were a few goals kept in mind when assembling the modules and collecting information to put them together. The most important thing is to fairly and effectively educate<br/>2<br/>students about their rights and the place they can hold in their own government. The youth in America, and specifically Arizona, with one of the lowest rated public education systems in the country1, needs to better understand the justice system and the way it works in order to really be able to better understand and decide the role they play in it as they grow into the adult population. We also aimed to teach students, mostly young adults, how to navigate being involved with the law and situations they may find themselves in like being arrested or having to go to court. The videos included in the related modules teach students what to do if they’re ever arrested and go over important legal actions that could affect their outcome. It was also important to provide instructors with a fair and trusted curriculum that can be taught across the state. With a shortage of qualified teacher in the state, it is impossible to provide students from all different districts and background with the same content. With the mandated civics test required to graduate from high school, it’s important that students get a fair chance at passing despite their living conditions or resources. With the modules we provide, passing the civics test along with managing other issues that pertain to young Americans, become attainable and don’t require as much additional time spent outside of school hours. The additional topics covered within our modules also provide information regarding resources that students will find useful for their families and loved ones. Students in compromised neighborhoods may have family and loved ones dealing with court cases and the justice system. Overall, we wanted to provide an unbiased, all-inclusive curriculum that can be used across the state to help students learn about all aspects of the government in Arizona.
The goal of this experiment was to examine the energy absorption properties of origami-inspired honeycomb and standard honeycomb structures. These structures were 3D printed with two different materials: thermoplastic polyurethane (TPU) and acrylonitrile butadiene styrene (ABS). Quasi-static compression testing was performed on these structures for both types and materials at various wall thicknesses. The energy absorption and other material properties were analyzed for each structure. Overall, the results indicate that origami-inspired structures perform best at energy absorption at a higher wall thickness with a rigid material. The results also indicated that standard honeycomb structures perform better with lower wall thickness, and also perform better with a rigid, rather than a flexible material. Additionally, it was observed that a flexible material, like TPU, better demonstrates the folding and recovery properties of origami-inspired structures. The results of this experiment have applications wherever honeycomb structures are used, mostly on aircraft and spacecraft. In vehicles with structures of a sufficiently high wall thickness with a rigid material, origami-inspired honeycomb structures could be used instead of current honeycomb structures in order to better protect the passengers or payload through improved energy absorption.
