A Battle Over 20th Century Textbooks: How The Civil War Is Still Fought In American Classrooms, Katie Court

History

This paper analyzed the emergence of Lost Cause history textbooks in the late 19th and early 20th centuries. Following the Civil War, Confederate societies such as the United Daughters of the Confederacy and United Confederate Veterans had a vested interest in positively portraying the South. From 1890-1930, Confederate societies attempted to expel textbooks that spoke unfavorably of the Confederacy, and instead encouraged states all around the country to follow stringent rules of how to discuss historical events. This research was led by material written by these societies and the textbooks they endorsed or expelled, in order to analyze the origins …

Trudging The Road Of Happy Destiny: The Gift Economy In Early Alcoholics Anonymous History And The Creation Of The Big Book, Timothy J. Parker

History

In 1939, Bill Wilson and his peers published Alcoholics Anonymous: The Story of How Many Thousands of Men and Women Have Recovered from Alcoholism, and in doing so, codified a spiritual gift economy through which millions of people have recovered from alcoholism and other addictions. This project examines the pragmatic formulation of this economy and argues its origins were driven as much by self-interest as altruism. It further explores the syncretic leadership of Bill Wilson and his mark on "The Big Book."

From Sidious To Nixon: The Parallels Between ​Star Wars​ And Vietnam, Brennan Simpson

History

In the case of a film franchise that features twelve movies, five television series, and various other forms of media by the time this paper was written, many people may be surprised to hear that Star Wars was actually inspired by one of the most questionable moments in American history. However, the time period in which Star Wars creator George Lucas first wrote what became this world’s ‘‘first step into a larger world’’ actually greatly reflected what ended up on the big screen. Even though the Star Wars movies take place ‘‘a long time ago in a galaxy far, far …

Potential Environmental Effects Of Deepwater Floating Offshore Wind Energy Facilities, Hayley Farr, Benjamin Ruttenberg, Ryan K. Walter, Yi-Hui Wang, Crow White

Physics

Over the last few decades, the offshore wind energy industry has expanded its scope from turbines mounted on foundations driven into the seafloor and standing in less than 60 m of water, to floating turbines moored in 120 m of water, to prospecting the development of floating turbines moored in ~1,000 m of water. Since there are few prototype turbines and mooring systems of these deepwater, floating offshore wind energy facilities (OWFs) currently deployed, their effects on the marine environment are speculative. Using the available scientific literature concerning appropriate analogs, including fixed-bottom OWFs, land-based wind energy facilities, wave and tidal …

Physical Activity Guidelines For People With Alzheimer’S Disease Of Various Ambulatory And Cognitive Status, Amanda Katherine Wright

Kinesiology and Public Health

With the rapidly growing elderly population in the United States, the number of people diagnosed with dementia and Alzheimer’s Disease (AD) is increasing dramatically. For these patients, it is crucial to slow the rate of progression. Research has proven that exercise improves cognition, and recent findings suggest a similar association among those with AD. However, this is complicated by the large majority of AD patients becoming non-ambulatory as the disease progresses. Thus, there is a large gap in the literature to meet the needs of non-ambulatory AD patients working to slow their disease’s progression. The first purpose of this article …

Pomegranate: Procedural 3d Tree Creation Via User-Defined L-Systems, Jeremy Berchtold

Computer Science and Software Engineering

Pomegranate creates procedural 3D trees based on a user-specified template. The template supports randomness and allows users to generate an entire forest of unique trees from a single template. The output trees are a single closed mesh without intersecting geometry (with the exception of leaves). Additionally, the output contains a skeletal rig used for animating the trees. Pomegranate produces textured trees that can use either a realistic or stylized look, as well as supporting different mesh densities for games or film. Since this project uses a procedural workflow, artists can quickly create and make edits to their trees. This increase …

Clustering Web Users By Mouse Movement To Detect Bots And Botnet Attacks, Justin L. Morgan

Master's Theses

The need for website administrators to efficiently and accurately detect the presence of web bots has shown to be a challenging problem. As the sophistication of modern web bots increases, specifically their ability to more closely mimic the behavior of humans, web bot detection schemes are more quickly becoming obsolete by failing to maintain effectiveness. Though machine learning-based detection schemes have been a successful approach to recent implementations, web bots are able to apply similar machine learning tactics to mimic human users, thus bypassing such detection schemes. This work seeks to address the issue of machine learning based bots bypassing …

Towards A Complete Formal Semantics Of Rust, Alexa White

Node Classification On Relational Graphs Using Deep-Rgcns, Nagasai Chandra

Master's Theses

Knowledge Graphs are fascinating concepts in machine learning as they can hold usefully structured information in the form of entities and their relations. Despite the valuable applications of such graphs, most knowledge bases remain incomplete. This missing information harms downstream applications such as information retrieval and opens a window for research in statistical relational learning tasks such as node classification and link prediction. This work proposes a deep learning framework based on existing relational convolutional (R-GCN) layers to learn on highly multi-relational data characteristic of realistic knowledge graphs for node property classification tasks. We propose a deep and improved variant, …

Seasonal Controls On Nearshore Hypoxia In A Small Coastal Embayment, Stephen Alexander Huie

Physics

Dissolved oxygen (DO) is an important biogeochemical factor that strongly influences nearshore coastal ecosystems. Low DO (hypoxic) events can cause physiological stressful environments for ecological and economically important species, potentially leading to mass mortalities. In order to better assess drivers of coastal hypoxia, we collected data from monthly cruises on the inner shelf and nearshore moorings inside and outside a small coastal embayment (San Luis Obispo Bay on the Central California Coast) across the full upwelling season (March to August). During the late spring and early summer, we found that the nearshore near-bottom temperature-DO (T-DO) relationship aligned with the shelf …
