Analysis of the Effects of Combustion Products on Forced Ignition and Turbulent Flame Propagation

Creator:: Bonebrake, Jonathan M.
Abstract:: Practical combustion devices frequently rely upon forced ignition of turbulent fuel/oxidizer mixtures that also contain the product species of combustion. Examples of this include engines that use exhaust gas recirculation (EGR), inter-turbine burners in aircraft engines, and other systems the utilize staged combustion. In this work, the effects of major...

Applications of Holographic Optical Tweezers: Multiplexed Fluorescence Spectroscopy and the Micromechanics of Type-I Collagen

Creator:: Cibula, Matthew A.
Abstract:: The development and some applications of holographic optical tweezers (HOT) are presented. Our HOT system uses a spatial light modulator (SLM) to control the location and properties of the optical trap. We have developed a method for optimizing the diffraction efficiency of a SLM that can be applied in situ...

Evaluating Multi-objective Trade-offs in Mature Douglas-fir (Pseudotsuga menziesii) Stands of Western Oregon

Creator:: Williams, Neil G.
Abstract:: Contemporary forest management involves a more extensive and diverse suite of management objectives than was the case throughout much of the Twentieth Century. Heightened public and political awareness of local and global biodiversity decline, and interest in arresting these trends, has increased the emphasis on broad-based biodiversity conservation as an...

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...

Using Algal Biomass as a Fertilizer

Creator:: Cappellazzi, Shannon B.
Abstract:: Algae can be used in a variety of wastewater systems to capture nutrients while fixing carbon dioxide from the atmosphere. I conducted field trials at three locations in Oregon with both corn and potato crops to assess the agronomic value and environmental impact of using the resulting algal biomass as...

Advances in Freshwater Cyanobacterial Genomics

Creator:: Brown, Nathaniel M.
Abstract:: Limnology is undergoing a transition to high-throughput -omic analysis of freshwater bacterial communities. An important first step in making the transition is to characterize several genomes that can be used as references to guide metagenome assembly and analysis. Here I characterize four new freshwater cyanobacterial genomes, a pair of lake...

A formal model of construction safety and health risk management

Creator:: Hallowell, Matthew R.
Abstract:: Despite recent efforts to improve site safety, construction still accounts for a disproportionate injury and illness rate. According to the 2007 injury and illness data released by the National Safety Council, the construction industry has a fatality and disabling injury rate that is approximately three times higher than the all-industry...

A Direction-Sensitive Radiation Detector for Low-Altitude, UAV-based Radiological Source Search

Creator:: Becker, Eric M. (Eric Matthew)
Abstract:: Many devices and methods for radiological searches are currently being developed, including scanning using simple detectors, mapping using large-volume detectors, and Compton imaging using 3-D position sensitive detectors. However, these devices are typically expensive and the methods used require long periods of time to generate a direction or location. The...

Computational Approaches for RNA Structure Prediction with Dynamic Programming and Deep Neural Networks

Creator:: Deng, Dezhong
Abstract:: Our goal is to build a system to model the RNA sequences that reveals their structural information by using efficient dynamic programming algorithms and deep learning approaches. We aim to 1) achieve linear-time for RNA secondary structure prediction based on existing minimum free energy models; 2) utilize deep neural networks...

Born to run? Integrating individual behavior, physiology, and life histories in partially migratory steelhead and rainbow trout (Oncorhynchus mykiss)

Creator:: Sloat, Matthew R.
Abstract:: Steelhead and rainbow trout are common names for marine-migratory (anadromous) and freshwater-resident forms of Oncorhynchus mykiss, a partially migratory salmonid fish. Anadromous and resident forms are sympatric and can produce offspring with a life history different from their own (i.e., steelhead parents can produce rainbow trout offspring and vice versa)....

Harnessing Heterogeneity in Human Gut Microbiome Data

Creator:: Tataru, Christine
Abstract:: The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....

Tradeoffs and Synergies among Wild Ungulates, Early Successional Plant Communities and Management Intensification in Forest Plantations of the Oregon Coast Range

Creator:: Stokely, Thomas D.
Abstract:: As the global demand for natural resources increases, more land will be intensively managed for the production of commodities such as timber, with potential consequences to biodiversity, ecological functioning and ecosystem services provided to society. Although there is strong consensus that intensive land management practices can negatively affect biodiversity, less...

Using Biodiversity Distribution Data to Support Landscape Conservation and Management in Colombia

Creator:: Zárrate-Charry, Diego A.
Abstract:: Global biodiversity decline is primarily driven by habitat loss. Deforestation, the primary driver of terrestrial habitat loss, is increasing worldwide, with the most significant impact in the world biodiversity hotspots. Sadly, specific knowledge of such impacts in biodiversity-rich but data-poor countries are still unknown, and many national and regional narratives...

Abstract:: The production of cement and concrete results in the production of large amounts of CO₂ emissions which can have significant negative environmental impacts. Using supplementary cementing materials (SCMs) as a cement replacement is an effective solution to reduce these negative environmental impacts, as most SCMs are waste by-products from other...

The Art of Reducing Coastal Hazard Complexity: Coupling Physics and Probability to Understand Extremes, Variability, and Climate-dependence

Creator:: Anderson, Dylan L.
Abstract:: Coastal hazards are the result of numerous physical processes cumulatively causing water levels to flood and erode the land. The waves, storm surges, tides, and run-off contributing to elevated water levels are each the product of chaotic and random weather patterns. These stochastic weather patterns dissipate energy in Earth's climate...
