Description
This thesis evaluates the viability of an original design for a cost-effective wheel-mounted dynamometer for road vehicles. The goal is to show whether or not a device that generates torque and horsepower curves by processing accelerometer data collected at the edge of a wheel can yield results that are comparable to results obtained using a conventional chassis dynamometer. Torque curves were generated via the experimental method under a variety of circumstances and also obtained professionally by a precision engine testing company. Metrics were created to measure the precision of the experimental device's ability to consistently generate torque curves and also to compare the similarity of these curves to the professionally obtained torque curves. The results revealed that although the test device does not quite provide the same level of precision as the professional chassis dynamometer, it does create torque curves that closely resemble the chassis dynamometer torque curves and exhibit a consistency between trials comparable to the professional results, even on rough road surfaces. The results suggest that the test device provides enough accuracy and precision to satisfy the needs of most consumers interested in measuring their vehicle's engine performance but probably lacks the level of accuracy and precision needed to appeal to professionals.

Description
This research project will test the structural properties of a 3D printed origami inspired structure and compare them with a standard honeycomb structure. The models have equal face areas, model heights, and overall volume but wall thicknesses will be different. Stress-deformation curves were developed from static loading testing. The area under these curves was used to calculate the toughness of the structures. These curves were analyzed to see which structures take more load and which deform more before fracture. Furthermore, graphs of the Stress-Strain plots were produced. Using 3-D printed parts in tough resin printed with a Stereolithography (SLA) printer, the origami inspired structure withstood a larger load, produced a larger toughness and deformed more before failure than the equivalent honeycomb structure.

Description
Throughout my experience in college, I learned many different techniques to communicate effectively. Most professors emphasized the importance of speaking clearly, and the ability to influence others. Dr. Kashiwagi piqued my interest when he explained his thoughts on how he wanted us to communicate to him. The criteria were simple, speak to him in a way that he could easily understand, without having to think. If thinking took place for him in the conversation, he determined that the person spoke too complexly and that his understanding of the student was low. After hearing this in class, I thought back to past conversations with my managers. I then wondered if I explained things clearer or simplified my wording, would things have gone better? I was also curious about simplicity in communication through writing, and how different presentations of information affected understanding. To further analyze these issues, I explored multiple research reports on verbal communication. Furthermore, I set up an experiment to test two common types of visual communication. The research concludes that Dr. Kashiwagi's theory was indeed correct, simplicity in conversation reduces miscommunication. The effectiveness of simplicity in written communication was partially proven by the survey results. The results indicated that the time required to fully understand a given topic dropped significantly if the information was depicted in a simplified format (list format). The more complex paragraph (textbook format) did have a higher level of understanding. However, the participants rated the textbook format job objectives as more complex, and stressful. After gathering the research, and running the experiment it can be concluded that by simplifying verbal communication, there are negligible differences in understanding of the topic, but the time of understanding decreases significantly.

Description
The vastly growing field of supercomputing is in dire need of a new measurement system to optimize JMRAM (Josephson junction magnetoresistive random access memory) devices. To effectively measure these devices, an ultra-low-noise, low cost cryogenic dipping probe with a dynamic voltage range is required. This dipping probe has been designed by ASU with <100 nVp-p noise, <10 nV offsets, 10 pV to 16 mV voltage range, and negligible thermoelectric drift. There is currently no other research group or company that can currently match both these low noise levels and wide voltage range. Two different dipping probes can be created with these specifications: one for high-use applications and one for low-use applications. The only difference between these probes is the outer shell; the high-use application probe has a shell made of G-10 fiberglass for a higher price, and the low-use application probe has a shell made of AISI 310 steel for a lower price. Both types of probes can be assembled in less than 8 hours for less than $2,500, requiring only soldering expertise. The low cost and short time to create these probes makes wide profit margins possible. The market for these cryogenic dipping probes is currently untapped, as most research groups and companies that use these probes build their own, which allows for rapid business growth. These potential consumers can be easily reached by marketing these probes at superconducting conferences. After several years of selling >50 probes, mass production can easily become possible by hiring several technicians, and still maintaining wide profit margins.

Description
The following paper discusses the validation of the TolTEC optical design along with a progress report regarding the design of the optical mounting system. Solidworks and Zemax were used in conjunction to model the proposed optics designs. The final optical design was selected through extensive CAD modeling and testing within the Large Millimeter Telescope receiver room. The TolTEC optics can be divided into two arrays, one comprised of the warm mirrors and the second, cryogenically-operated cold mirrors. To ensure structural stability and optical performance, the mechanical design of these systems places a heavy emphasis on rigidity. This is done using a variety of design techniques that restrict motion along the necessary degrees of freedom and maximize moment of inertia while minimizing weight. Work will resume on this project in the Fall 2017 semester.

Description
This Barrett, the Honors College senior thesis connects the experiences of cosplay with public speaking confidence. “Cosplay, abbreviated from the word ‘costume play,’ is a performance art in which the participant masquerades as a character from a selected film, television, video game, or comic book” (Gn, 2011, p. 583). The ability to “cosplay” in front of other relies on performing in front of an audience much like public speaking. When students speak with confidence, students will know their ideas are being expressed with conviction and assurance. Having the ability to speak professionally and publicly, is a highly valued skill in the workforce and key to success in all types of employment. Communication skills are frequently a top factor in determining whether a college student will obtain employment (Beebe & Beebe, 2006, p. 275-276). Despite their different definitions, there are multiple connections between cosplay and public speaking. This thesis explores the connection between peer support and belief in one’s self in both cosplay and public speaking. Now those who have direct support become self-reliant and confident as a result of these connections. This projects highlights Goffman’s identity theory, the Pygmalion effect, theories of fashion and identity, role-play, narrative paradigm, dramatism, and non-verbal communication, and explores how cosplay can contribute to the formation of one’s public speaking persona. The issue of anxiety is also included in the conversation as it is central to both cosplay and public speaking. Ultimately, this thesis explores the questions: Can cosplay help students become empowered public speakers?

Description
The foundations of legacy media, especially the news media, are not as strong as they once were. A digital revolution has changed the operation models for and journalistic organizations are trying to find their place in the new market. This project is intended to analyze the effects of new/emerging technologies on the journalism industry. Five different categories of technology will be explored. They are as follows: the semantic web, automation software, data analysis and aggregators, virtual reality and drone journalism. The potential of these technologies will be broken up according to four guidelines, ethical implications, effects on the reportorial process, business impacts and changes to the consumer experience. Upon my examination, it is apparent that no single technology will offer the journalism industry the remedy it has been searching for. Some combination of emerging technologies however, may form the basis for the next generation of news. Findings are presented on a website that features video, visuals, linked content, and original graphics. Website found at http://www.explorenewstech.com/

Description
This project focuses on techniques contemporary American poets use in their work. Ten different poetry collections are analyzed for dominant writing styles and techniques, which I then apply to my own poems, concentrating on modeling that particular poet. I then reflect on those poems through an evaluation of my writing process, how those techniques were implemented, and how they affected the poem. In addition to these reviews and reflections, I also wrote three articles about the literary community and what I've learned from my interactions in that community. All these materials are organized into a website, which shows the connections between the different writings via links and menus. Creating this website brings all the materials together to demonstrate my growth as a poet, writer, and designer. This heavy focus on poetry and analysis has helped sharpen my critical thinking skills and has better prepared me for a career in design and journalism.

Description
The transition from high school to college is marked by many changes, one of the most significant being the increased accessibility of alcohol, putting college students at high risk for alcohol-related consequences. It is imperative to identify factors that can protect young adults against these risks during this critical period. Although peers become increasingly influential in college, extant literature has shown that parents still have an impact on their children's behavior during this time. While parents spend less time with their children after college matriculation, they may indirectly protect against risky drinking behaviors by instilling certain values into their children before they make this transition. Using data from a large sample of students during their senior year of high school and their freshman year of college, the current study sought to examine interactive effects of parental communication and parental knowledge and caring on drinking behavior, and the extent to which internalization of personal drinking values mediate these effects. The primary study hypotheses were tested using path analysis conducted in Mplus 7.0. Full information maximum likelihood (FIML) estimation was utilized to estimate missing data and bootstrapping was used to address non-normality in the data. Results showed that, for those whose parents were high in knowledge and caring, higher levels of communication were associated with lower risk for alcohol use and problems at wave 3 through less permissive drinking values at wave 1. This finding has important implications for prevention approaches designed to reduce risk for heavy drinking and related problems during the transition to college.
