Improving And Evaluating Performance Of The Proton Prediction System Through An Expanded Solar Proton Event Catalog, Samantha R. Howard Sep 2023

Improving And Evaluating Performance Of The Proton Prediction System Through An Expanded Solar Proton Event Catalog, Samantha R. Howard

Theses and Dissertations

Solar energetic particles (SEPs) are especially high energy protons (≥ 5 or 10MeV kinetic energies) originating from the Sun that are known to have significant effects on space-based military operations. The Air Force’s current forecast model, the Proton Prediction System (PPS), forecasts less than half of SEP events that are observed, motivating the need for an update to the operational model. To develop the updated PPS model, PPS2.0, an expanded SEP catalog was produced, which includes 103 previously unidentified events and specification of the proton flux response above background levels or prior events. Event detection and source association were initially …

Advanced Statistical Methodology For The Modern Probability Of Detection, Christine E. Knott Sep 2023

Advanced Statistical Methodology For The Modern Probability Of Detection, Christine E. Knott

Theses and Dissertations

Probability of detection (POD) is an invaluable part of the calculations used by the USAF to validate the capabilities of nondestructive inspection systems for detecting defects in critical structural components on aircraft. A POD study consists of a designed experiment, linear modeling, and a probability of detection verses defect size curve. This curve is useful for determining how often an aircraft should be re-inspected. Some POD studies are unsuccessful in creating realistic POD curves because the statistical modeling used has two common limitations: (1) a lack of convergence leading to no solution and, (2) violated assumptions leading to incorrect solutions. …

Parental Roles In K-12 Online Education, Barbara Tanner Sandberg Aug 2023

Parental Roles In K-12 Online Education, Barbara Tanner Sandberg

Theses and Dissertations

Parental support roles in K-12 online learning differ from traditional schools. Since K-12 students typically have not developed the self-regulation skills necessary for academic engagement, parents partner with schools to provide the affective, behavioral, and cognitive engagement support necessary for academic success. Through 21 semistructured interviews with parents supporting K-12 students in varied online contexts, this study delineates how parents provided support in each of these dimensions of engagement. The participants felt that in online education, parents should take the primary responsibility for behavioral engagement support, and that teachers were primarily responsible for cognitive support.

Phosphorus Sorption And Kinetics Across The Sediment-Water Interface Of Utah Lake, A Shallow Eutrophic Lake, Forrest Fielding Stretch Jarvis Jarvis Aug 2023

Phosphorus Sorption And Kinetics Across The Sediment-Water Interface Of Utah Lake, A Shallow Eutrophic Lake, Forrest Fielding Stretch Jarvis Jarvis

Theses and Dissertations

Internal sediment phosphorus (P) cycling may regulate harmful algal blooms (HABs) in shallow eutrophic lakes. Utah Lake frequently experiences HABs despite its high alkalinity and P-rich sediment. Phosphorus cycling between the lakebed and the water column is dependent upon stable P-sorption with organic matter (OM) and mineral species, which can vary with substrate availability, P-concentrations, temperature, redox, pH, and microbial activity. A full biogeochemical analysis of the water and sediment across seven sites shows Utah Lake to be spatially well-mixed in terms of composition and sorption, with few exceptions. Sediment P-concentrations (avg. 677 mg-P kg-1) primarily correlate with redox-sensitive iron …

Grief In Children With Disabilities And How It Is Portrayed In Children's Picture Books, Erjola Gjini Aug 2023

Grief In Children With Disabilities And How It Is Portrayed In Children's Picture Books, Erjola Gjini

Theses and Dissertations

Even though today's children's literature provides a wide range of topics, including books on death and grief, and much has been done to represent children with disabilities accurately and positively, there is still room for improvement. This descriptive study sought to understand how individuals with disabilities were represented in 177 grief-themed children's books from 1965-2023. From the results, only seven books included representations of individuals with disabilities. Additionally, the literary devices such as euphemisms or metaphors utilized in the books to describe how death was represented may inadvertently perpetuate inaccessibility to resources about grief (Berns, 2004). Thus, when choosing books …
