The Gear Up Experience: What Leads To College?, Erik Dickamore
The Gear Up Experience: What Leads To College?, Erik Dickamore
Student Research Symposium
Gear up is a 6-year federal grant whose purpose is to encourage and support underprivileged students to enroll in and succeed in higher education. Gear up was deployed in 11 school districts across the state 5 and 1/2 years ago. Ambiguity arises when trying to assess the Gear Up program as a whole because each student's experience within the program varies. My research focuses on using advanced statistical techniques ie. a latent profile analysis (LPA) to look at the holistic experience of Gear Up Students. Results highlight the link between different profiles of experiences within the Gear Up program and …
The Effects Of Radiation-Induced Defects On The Electrostatic Discharge Of Polymers, Kip Quilter, Alexandra Hughlett
The Effects Of Radiation-Induced Defects On The Electrostatic Discharge Of Polymers, Kip Quilter, Alexandra Hughlett
Student Research Symposium
Test were done to see how radiation-induced defect states affect the electrostatic discharge (ESD) breakdown potential of a material. We selected five different highly disorder polymers (PEEK, PI, FEP, PP, LDEP) due to their different tolerances to radiation. By irradiating samples with 5kGy of penetrating beta radiation in vacuo, we created more localized trap states in the polymers; this is known to increase hopping conductivity. It has also been hypothesized that post-irradiation exposure to oxygen or water in air can repair these defects. ESD can be viewed as an extreme limit of conductivity and therefore is expected to decrease as …
Climate Change At Utah Ski Resorts: Impacts, Perceptions, And Adaptation Strategies, Emily Wilkins, Tara Saley, Hadia Akbar, Rachel Hager
Climate Change At Utah Ski Resorts: Impacts, Perceptions, And Adaptation Strategies, Emily Wilkins, Tara Saley, Hadia Akbar, Rachel Hager
Student Research Symposium
Utah sees over four million skier visits per season, which has substantial economic impact across the state. However, climate change may affect the operability of these ski resorts, which could also impact local businesses and communities. With warming temperatures and changes in precipitation patterns, the future of Utah's ski resort industry may be uncertain. We conducted an interdisciplinary study to understand how past weather has changed at the resorts and what climate may be like in the future. We studied this using publically available weather data from PRISM, Daymet, and the National Snow and Ice Data Center, and climate change …
Temperature-Dependent Conductivity Of Highly Insulating Polymers, Megan Loveland, Brian Wood
Temperature-Dependent Conductivity Of Highly Insulating Polymers, Megan Loveland, Brian Wood
Student Research Symposium
Temperature-dependent electrical conductivity measurements of polymers are compared to predictions by thermally assisted hopping conductivity, commonly used to model electron transport between defect sites in highly disordered insulating materials (HDIM). Constant voltage is applied across samples using a parallel plate geometry under vacuum, with the resulting current measured using a high resolution electrometer to calculate extreme low level conductivity. Conductivity of thin film PEEK (polyether ether ketone) and LDPE (low density polyethylene) samples was measured at temperatures ranging from 270 to 350 K to determine temperature influence on conductivity. Long time scales are needed for polymers to reach electrostatic equilibrium …
Gravitational Anomalies & Elliptic Curves, Michael T. Schultz
Gravitational Anomalies & Elliptic Curves, Michael T. Schultz
Student Research Symposium
A gravitational anomaly is a special type of curvature that is important in string theory. Elliptic curves are very important and ubiquitous in mathematics - for example, it was a special property of some families of elliptic curves that was instrumental in proving the famous Fermat's Last Theorem. In the context of my research, an elliptic curve is a torus defined by a simple polynomial equation. My research shows that every suitably general one parameter family of elliptic curves (called an elliptic fibration with section) has both local and global gravitational anomalies. In my talk, I will explain these anomalies …
Quaternions, Octonions, And Electromagnetism, Ben Shaw
Quaternions, Octonions, And Electromagnetism, Ben Shaw
Student Research Symposium
An introduction to Quaternions and Octonions is given, and the Maxwell Equations are formulated in terms of each. The conventional, source-free relativistic theory of eight dimensional electromagnetism is introduced and examined. Similarly, the source-free Octonionic Maxwell Equations are developed, and it is shown that the seven dimensional electric and magnetic fields pure Octonions each admit plane wave solutions. An Octonionic Faraday tensor is constructed and compared with the conventional Faraday tensor, and it is shown that, in the source-free case, the conventional and Octonionic theories are equivalent.
