Enhancing Facial Recognition: A Comparative Analysis of Image Preprocessing Techniques in PCA, KL Expansion and SVD

Creator:: Tuffour, Prince A.
Abstract:: Facial recognition has become increasingly important in recent years, due to the wide range of applications it has in fields such as security, surveillance, and human-computer interaction. Three popular methods for facial recognition are the Principal Component Analysis (PCA), Karhunen-Loeve Expansions, which is fundamentally a continuous form of PCA but...

Dynamic Probabilistic Risk Assessment Using ADAPT/RELAP5-3D for Cybersecurity Threat Analysis

Creator:: Wiltbank, Nathan E.
Abstract:: There is a growing need for an expanded Probabilistic Risk Assessment (PRA) framework that is able to accommodate new uncertainties that are present in Generation 3+ reactor designs. Dynamic PRA (DPRA) can allow for a more realistic risk assessment by taking advantage of established nuclear simulation codes to drive Dynamic...

Susceptibility of juvenile salmonids to avian predation : Are Caspian terns and double-crested cormorants only taking the sick and injured?

Creator:: Hostetter, Nathan J.
Abstract:: The ability to non-destructively assess fish condition and subsequently track fish behavior and survival can be vital in understanding natural and anthropogenic stressors and sources of mortality, especially in populations of fish listed as threatened or endangered. I investigated the use of a quick, non-lethal, external examination technique to assess...

Removal of E. coli with alternative media Biosand filters

Creator:: Fulton, Nathan J.
Abstract:: When Biosand filters cannot be constructed with crushed quarry rock due to resource limitations, a suitable alternative filter media is needed. In this research, two crushed quarry rock alternatives were examined. Three bench-scale Biosand filters with crushed rock, beach sand, and heat-treated beach sand media were simultaneously dosed with Willamette...

First-Year Mentorship Program Influence on Second-Year Student Success

Creator:: Petitti, Nathan J.
Abstract:: Second-year students are a population that is often overlooked by higher education institutions. Many programs are offered to foster the success of students, but there is little research on their influence on second-year students. Mentorship initiatives are well researched and utilized support programs for students, but relatively little research has...

Population Ecology of the Mariana Swiftlet (Aerodramus bartschi) on O'ahu, Hawaiian Islands

Creator:: Johnson, Nathan Christopher
Abstract:: The Mariana Swiftlet (Aerodramus bartschi) (Aves: Apodidae) is endemic to the Mariana Islands, where it currently occurs on Saipan, Aguiguan, and Guam. An introduced population of Mariana Swiftlets is also present on O'ahu in the Hawaiian Islands. Sparing interference with the endangered population in the Marianas, the introduced, surrogate population...

Effects of body size on the survival and timing of emigration of newly metamorphosed Northern Red-legged frogs

Creator:: Chelgren, Nathan D.
Abstract:: The purpose of this study was to investigate the survival and movements of newly metamorphosed Northern Red-legged frogs (Rana aurora aurora) as they emigrated from two ephemeral breeding ponds. Quantifying survival and movement rates will be important to our understanding how changes to terrestrial and aquatic systems affect behavior and...

Ecology of Columbian black-tailed deer fawns in western Oregon

Creator:: Pamplin, Nathan P.
Abstract:: Little is known about Columbian black-tailed deer (Odocoileus hemionus columbianus) because of their elusive nature and the logistical difficulty of studying them in densely forested and mountainous terrain. The Oregon Department of Fish and Wildlife has identified fawn survival as an important gap in the current knowledge of demography and...

Effects of whole body vibration and progressive resistance exercise on balance and lower extremity strength

Creator:: Dodge, Nathan
Abstract:: Whole body vibration (WBV) is widely used as a mechanical stimulus for neuromuscular training, and to a lesser extent, in the treatment of patients undergoing physical rehabilitation. PURPOSE: To quantify any beneficial and/or synergistic effects associated with the longitudinal administration of WBV and progressive resistance (PRE) exercise on lower extremity...

The effects of differing hazelnut concentrations in hog finishing rations with respect to pork shelf-life and fatty acid composition

Creator:: Parker, Nathan B.
Abstract:: Commercial hog diets in the United States commonly contain lipid sources high in polyunsaturated fatty acids, most notably linoleic acid (18:2). This may result in greater deposits of linoleic acid in pork adipose tissue, contributing to an increased potential for lipid oxidation, high n-6/n-3 fatty acid ratio and increased fat...
