This thesis addresses the problem of learning dynamic Bayesian network (DBN) models to support reinforcement learning. It focuses on learning regression tree models of the conditional probability distributions of the DBNs. Existing algorithms presume that the stochasticity in the domain can be modeled as a deterministic function with additive noise....
Determining the electrical properties of ceria-based materials is important for their use as electrodes in hot-wall magnetohydrodynamic (MHD) power generators with wall temperatures greater than 1500 ̊C. The electrical conductivity of a material can be used in models for predicting the performance of generator designs. More specifically, the temperature dependent...
The literature on first-generation South Asian American (SAA) mental health is limited despite the increased focus of studies on help-seeking behaviors and subjective well-being over the past decade. Therefore, we designed a web-based survey seeking to address two research questions. Research Question 1 informed Study 1 of this dissertation project:...
Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...
Agrobacterium tumefaciens and Rhodococcus fascians are plant pathogenic bacteria that can induce crown and leafy galls on plants, respectively. Infection by these bacteria results in disfigured, unsellable plants, leading to significant economic losses to the nursery industry. A. tumefaciens and R. fascians are capable of infecting a broad range of...
Over the last 50 years, riparian zones in the semi-arid West have gained recognition as disproportionately important habitats for both breeding bird communities and agricultural operations. Despite growing interest in exploring avian-habitat relationships in these systems to better inform land management, few studies have attempted to describe temporal changes in...
The low-level baroclinic eddy activity seen in the NASA Ames Mars General Circulation Model (MGCM) for simulations under three annual dust cycles are characterized. Simulations were conducted with both radiatively active and radiatively inert clouds (RAC and non-RAC, respectively) for 11 continuous annual cycles for each dust case. Model results...
Sixteen secondary school health teachers evaluated their own
course teaching performance. Students in each of these courses
evaluated the same teacher and the results were compared. An
adapted version of a teacher rating form developed by the School of
Agriculture, Oregon State University, was used by all study participants.
Teacher...
Accurate determinations of body composition, fat mass (FM) and fat-free
mass (FFM) are of interest to scientists as well as many individuals
who serve as health and fitness practitioners. Currently, researchers and
practitioners use a variety of indirect methods to determine body
composition. Traditional methods of estimating percent body fat...
The Brush less Doubly-Fed Machine (BDFM) has the potential to be a more cost effective replacement for conventional induction or synchronous machine drives. The BDFM has two stator windings: a power winding and a control winding. An electronic power converter of variable voltage and frequency is connected to the control...
Volatile loss rates of pesticides from turfgrass were measured using the Backward-Time Lagrangian Stochastic Dispersion model (Flesch et al., 1995). Solar radiation, ambient temperature, surface temperature, relative humidity, wind direction, and wind speed were monitored continuously. Growth regulator was applied to the turf plot several days before pesticide application to...
The feasibility of using lumber and plywood futures as a means of cross product hedging for stumpage is explored from the standpoint of the producer of forest products. A survey conducted in April, 1979 Indicates that this process has not been attempted in western Oregon. Historical price relationships between contract...
Soil erosion research in the fields of agronomy, soils science
and mechanics, agricultural engineering, hydrology, climatology, and
other scientific disciplines has economic dimensions. In general,
measurable and, at times, significant economic effects are
associated with the effects of erosion in the other disciplines.
Interactions between climate, soils, hydrology, and tillage...
Few studies have examined the partitioning of organic matter in upwelling systems,
despite the fact that these systems play a key role in carbon and nitrogen budgets in the
ocean. We examined the production and partitioning of phytoplankton-derived organic
matter in deck incubations off Oregon during the upwelling season. During...
We monitored larval Lost River and shortnose suckers from natal beds in the Williamson and Sprague rivers to nursery grounds in Upper Klamath Lake. Downstream movements occurred at night, in the middle of the channel, and on the falling limb of the hydrograph. Ages, sizes, and developmental stages of larvae...
Fire exclusion has been associated with structural and compositional changes
in many upland forests of the western United States, but little is known about the
impacts on riparian forests, portions of the landscape protected for habitat and water
quality. For this study, I characterized the historic disturbance and tree recruitment...
Experiments were designed to answer key questions about diatom-derived organic matter cycling (i.e., production and degradation) in coastal systems. Dissolved organic matter (DOM) production was examined in axenic batch cultures of five diatom species. Dissolved organic carbon (DOC) release rates varied between species, but were significantly higher for all species...
Large numbers of hatchery salmon spawn in wild populations each year. Hatchery
fish with multiple generations of hatchery ancestry often have heritably lower
reproductive success than wild fish and may reduce the fitness of an entire population.
Whether this reduced fitness also occurs for hatchery fish created with
local- and...
