Vibro-Acoustic Analysis Of A Fan Blade, Matthew Koithan

2022 Spring Honors Capstone Projects - Archive

A frequent problem with rotating machinery is vibration. Vibration in a rotating part can be caused by unequal mass distribution. A sound or acoustic wave is created by a pattern or disturbances traveling through a medium. Vibration and Acoustics can be dealt with individually, however, if they share a common source, both could be solved simultaneously. The purpose of this project is to correlate the fan noise to the rotor imbalance. The unbalanced mass can be removed by aligning the center of gravity (CG) with the axis of rotation, which eliminates any coupled moments. The vibration is measured using accelerometers …

United Nations Peacekeepers, The Use Of Sexual Exploitation And Abuse, And Feminist Theory, Corrina Marie Sullivan

2022 Spring Honors Capstone Projects - Archive

Why do United Nations peacekeepers enact sexual harm against the very populations they are meant to protect? Given that the purpose of United Nations peacekeepers is to promote peace in a country following a period of unrest and/or violence, acts of sexual exploitation and abuse are antithetical to their purpose. These acts also inflict trauma on populations meant to be protected. Finally, this behavior undermines the general trust in the United Nations. Therefore, when peacekeepers engage in acts of sexual exploitation and abuse, these acts have larger implications for not only the peacekeeping force but the United Nations as a …

Agricultural Carbon: The Land, Landowner, And Farmer, Barclay Rogers

Journal of Food Law & Policy

Carbon is certainly a hot topic in agriculture. Across the countryside, farmers, landowners, agricultural service providers, and many others are trying to understand what carbon is about and what it may mean to them. One of the more interesting topics around agricultural carbon concerns the relationship between the landowner and tenant farmers on absentee-owned land (i.e., land that is farmed by someone other than the person who owns it). This article provides a brief background on the agricultural carbon opportunity and explores some ideas about how to pursue the opportunity on absentee-owned farmland.

Estimating Cattle Density Using Wildlife Cameras, Emily Bonebrake

Undergraduate Honors Capstone Projects

Quantifying the abundance and distribution of animal populations is critical for effective wildlife research and management. Due to their cost-effectiveness, wildlife cameras have become an increasingly popular tool for estimating population densities. Previously, this technique relied on ‘capture-recapture’ models that utilized re-sightings of individually marked animals, but in recent years methods have been developed to estimate the population densities of unmarked animals. One such method is the random encounter and staying time (REST) technique, which does this by assuming that the cumulative time animals stay within the view of the camera scales linearly with the number of individuals. This allows …

Bridging The Divide Between Upper And Lower Classmen: Resources For Mentors And Freshmen In The Choral Education Program, Tanner Hancock Pruett

Undergraduate Honors Capstone Projects

The recent decline in student retention in the choral education program at Utah State University should be cause for concern. Students who are excited and passionate about choir are leaving choral education and/or dropping out of college entirely. However, research into college retention rates and the experiences of choral education students at USU has helped explain this decline in student retention.

My review of research about college retention rates indicates that some of the biggest reasons that students drop out of college are academic difficulty, interpersonal difficulties, and mental health. It also indicates students with a strong sense of support …

The Evolution And Unraveling Of The American Eugenics Movement, Anneka Walton

Undergraduate Honors Capstone Projects

While the evolution of American eugenics surrounding the time of Nazi Germany has been well-documented, the periods before the explosion of American eugenics and the result of the movement in the wake of the Holocaust are not so well known. Many historically-based works have described the path and growth of eugenics from the time the term was coined to the public acknowledgement of World War II and the point where Americans ended eugenic euthanasia and slowed eugenic sterilizations. There are also many works within the realm of disability history that document these events from the more common social viewpoint. This …

Western Christianity And The Origins Of Antiblackness, Eurocentrism, And White Supremacist Ideology., John Chenault

Electronic Theses and Dissertations

This qualitative study investigates the cult(ural) and intellectual history of Western Christianity to address a significant gap in the literature pertaining to the origins of whiteness/antiblackness in the West and its subsequent socialization worldwide. Western Christianity’s seminal role in the social construction of the whiteness/antiblackness dichotomy has been undertheorized, neglected, and ignored. This study finds early Christian theologians categorically imposed conceptual metaphors about Blackness on African people that depicted them as the exemplars of evil to teach Christian doctrine about sin and salvation. It connects these original antiblack discourses directly to the theo-political arguments Western European Christians used centuries later …

Ashley: A Chamber Opera In Four Scenes., Rron Karahoda

Electronic Theses and Dissertations

This thesis is an intimate chamber opera which explores an original story of a young woman finding her place in the world at the same time she is dealing with unresolved feelings of regret, jealousy, and confusion over her sister’s death. This journey is complicated by people on all sides seeking to benefit by exploiting her and her sister’s legacy. As these two threads collide, the opera reveals itself to be about introducing and synthesizing dualities (in the dialectical sense of thesis→antithesis→synthesis), both musically and dramatically. Octatonic and whole tone pitch sets learn to intermingle, as do whole families of …

The Gambler's Edge - A Theoretical Framework To Trading Securities, Matthew Haines

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Like gamblers, retail investors seeking excess returns in financial markets are prone to miscalculation and their models are often misspeciffied. Forecasting asset prices is extremely difficult in the long run and nearly infeasible in the short run. Additionally, retail investors are likely to be at a disadvantage both technologically and informationally—rarely will they be ahead of the curve. With these disadvantages and the difficulty of predicting future outcomes, retail investors may come to view prices as unpredictable and random in nature, like a roll of the dice. This theoretical research explores a possible investing methodology (derived from gambling principles) should …

Calibration Procedure For Dic Strain Measurements During Vibration-Based Fatigue Testing, Benjamin D. Hill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Vibration-based fatigue testing is fast and effective method for determining failure characteristics of a material. Often, a small electrical device called a strain gage is bonded to a rectangular plate specimen to measure the deformation of the plate during a test. However, these strain gages break before the plate does, so an alternative method would improve the results obtained from the test. As an alternative to strain gages, Digital Image Correlation (DIC) is a non-contacting, camera-based technique that measures the deformation of an object by comparing digital images taken before and after the object is deformed. During a vibration-based fatigue …
