Selection-Based Convolution For Irregular Images And Graph Data, David Marvin Hart

Theses and Dissertations

The field of Computer Vision continues to be revolutionized by advances in Convolutional Neural Networks. These networks are well suited for the regular grid structure of image data. However, there are many irregular image types that do not fit within such a framework, such as multi-view images, spherical images, superpixel representations, and texture maps for 3D meshes. These kinds of representations usually have specially designed networks that only operate and train on that unique form of data, thus requiring large datasets for each data domain. This dissertation aims to bridge the gap between standard convolutional networks and specialized ones. It …

Money People: An Examination Of Wealthy Characters In Fiction, Morgan (Yeatts) Eley

Masters Theses

This thesis seeks to examine the similarities (or dissimilarities) of wealthy characters in fiction, specifically studying two well-known wealthy characters: Mr. Darcy from Pride and Prejudice and Jay Gatsby from The Great Gatsby. The study examined the first impressions of these characters, their attitudes toward others, their physicalities and presences, and how they spent their money. These examinations yielded fairly similar results between the two characters, as discussed in depth within the thesis. The most obvious similarity was the way the authors wrote their characters in a “set apart” manner, creating a division between them and the other characters. While …

Beyond The Long Walk: Appealing To A Target Audience Through Genre Choice And Manuscript Length, Stacie Ann Sudkamp

Masters Theses

Creatively writing specifically for a narrow target audience has not historically been the modus operandi of most authors. The usual recommendation has been to allow a story’s characters to determine plot direction, story length, and genre. My Artist Statement explains my motivation for creating a manuscript that appeals, specifically, to servicemembers and veterans coping with PTSD and suicidal ideation. Furthermore, the research expanded upon in my Critical Paper supports my decision to create a hybrid, or mixed genre, novella in order to capture and hold the attention of my target audience in a unique way. I accomplish this by first …

Implementing Outpatient Screening Of Adult Patients At High Risk For Peripheral Artery Disease, Coral Roseberry

Doctor of Nursing Practice Final Manuscripts

Background: Peripheral artery disease (PAD) is a prevalent chronic vascular disease that remains often underdiagnosed and inadequately treated. The development of PAD increases both with age and with the presence of modifiable and non-modifiable risk factors. Risk factors for PAD include smoking, diabetes, hypertension, hyperlipidemia, and chronic kidney disease. Furthermore, PAD can be an indicator of systemic atherosclerosis which is associated with coronary artery disease, carotid stenosis, and cerebrovascular disease. Undiagnosed obstructive PAD contributes to damaging atherosclerotic sequelae such as claudication, ulcers, infections, peripheral neuropathy, and amputations. It is common for PAD to exist in the absence of symptoms; therefore, …

Making And Meaning In The Study Of Biblical Stories: A Case For A Unified Approach To Narrative Criticism, Todd Michael Oakes

Doctoral Dissertations and Projects

The purpose of this study is threefold and involves looking across the disciplines of literary theory and criticism, hermeneutics, exegesis, and theology in the analysis of biblical literature. In the areas of literary theory and criticism this involves looking at poetics, modern linguistic theory, structuralist criticism, mimetic theory, and the elements of narrative storytelling. For hermeneutics we will measure how one might best interpret a story comparing the differences between text-centered, reader-centered, and author-centered approaches. Regarding exegesis we will advance an argument for the adoption of the grammatical-historical method over any other. This will allow us to make a case …
