Material Appearance Modeling For Physically Based Rendering, Alexis Benamira

Graduate Thesis and Dissertation 2023-2024

Photorealistic rendering focuses on creating images with a computer that imitates pictures of reallife scenes as faithfully as possible. To achieve this, rendering algorithms require incorporating accurate modeling of how light interacts with various types of matter. For most objects, this model needs to account for the scattering of the light rays. However, this model falls short when rendering objects of sizes smaller or comparable to the wavelength of the incident light. In this case, new phenomena such as diffraction or interference are observed and have been characterized in optics. Digital rendering of those phenomena involve different light representations than …

Propaganda Of Car Ecotourism In Glacier National Park, Hanna Y. Mohammed

Honors Undergraduate Theses

This paper discusses the promotion of car ecotourism and its impact on Glacier National Park. Coinciding with the creation of the park's flagship Going-to-the-Sun Road from 1921 to 1932, both the state and the private sector presented the image of the newly commodified automobile as a vehicle to explore nature with. Historically, national parks have served the interests of the middle and upper classes, by suppressing marginalized communities, primarily through forced relocation in order to clear the lands for creation of the parks. The public's conception of the “wilderness” drastically changed during the time the car was commodified, as nature …

Local-Level Maternal And Infant Health: A Mixed-Methods Analysis Of The Relationship Between Social Determinants Of Health, Maternal And Infant Health Outcomes, And Public Health Programs In Florida, Jacquelyn Reiss

Electronic Theses and Dissertations, 2020-2023

Current data highlight significant disparities in infant and maternal health (IMH) outcomes both when comparing outcomes to other countries and between groups within the U.S. Previous studies indicate that disparities in health outcomes are caused by health inequities. Health inequities are a result of marginalized groups historically being denied resources and exposed to increased risk directly impacting health. These resources and risks are considered social determinants of health (SDoH), such as income, housing, transportation, and access to care. Although SDoH influence individuals across multiple levels of society, communities are sites where individuals directly access protective resources and are potentially exposed …
