Barrett

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.

Tribological Failures of Wind Turbine Bearings

Although wind turbine bearings are designed to operate 18-20 years, in the recent years premature failure among these bearings has caused this life to reduce to as low as a few months to a year. One of the leading causes of premature failure called white structure flaking is a mechanism that was first cited in literature decades ago but not much is understood about it even today. The cause of this mode of failure results from the initiation of white etched cracks (WECs). In this report, different failure mechanisms, especially premature failure mechanisms that were tested and analyzed are demonstrated as a pathway to understanding this phenomenon. Through the use of various tribometers, samples were tested in diverse and extreme conditions in order to study the effect of these different operational conditions on the specimen. Analysis of the tested samples allowed for a comparison of the microstructure alterations in the tested samples to the field bearings affected by WSF.

This research examines the presentation of ASD in fictional children's literature. The goal is to use the research collected to determine what symptoms of ASD are receiving coverage versus what is not being covered but needs to be in a children's book about ASD. This was accomplished by first consulting background literature on ASD before examining 40 children's books about characters on the spectrum. It was found that girls on the spectrum received less coverage than boys did, and that most books conformed to one of two types: looking at ASD through the eyes of a neurotypical child and looking at it through the eyes of a child who has it. This led to the proposed idea of a book about a girl on the spectrum that would alternate between her point of view and the point of view of her neurotypical friend, and the subsequent draft of said book.
