Learning MDP action models via discrete mixture trees

Creator:: Wynkoop, Michael S.
Abstract:: 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....

High Temperature Electrical Properties of Ceria-Based Ceramics for Use as Electrodes in Magnetohydrodynamic Power Generators

Creator:: Bowen, Michael S.
Abstract:: 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...

Predicting Help-Seeking Attitudes and Intentions and Life Satisfaction of First-Generation South Asian Americans Based on Acculturation Levels, Select Demographics, and Forms of Racial Stereotyping

Creator:: Michaels, Krupali S.
Abstract:: 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:...

Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

Creator:: Bowen, Michael S.
Abstract:: 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...

Characterizing novel bacterial isolates that inhibit the growth of gall-forming phytopathogenic bacteria

Creator:: Belcher, Michael S.
Abstract:: 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...

Twenty-year changes in riparian bird communities of east-central Oregon

Creator:: Ellis, Michael S.
Abstract:: 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 effects of clouds on transient baroclinic eddies in a Mars General Circulation Model

Creator:: Rucker, Michael S.
Abstract:: 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...

Chemical and environmental factors affecting pesticide volatilization from turfgrass

Creator:: Conway, Michael S.
Abstract:: 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...

Cross product hedging for stumpage using forest product futures: a Pacific Northwest exploratory study

Creator:: Meredith, Michael S.
Abstract:: 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...

Production and partitioning of organic matter during simulated phytoplankton blooms

Creator:: Wetz, Michael S.
Abstract:: 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...
