A GIS analysis procedure was developed to explore relationships between imagery, yield data, soil information, and other assessments of a field or orchard. A set of conversion utilities, a spreadsheet, and an inexpensive shape file viewer were used to manipulate, plot, and display data. Specific features described include procedures used...
In March 2005 the Oregon State University Herbarium launched its new, free online Oregon Vascular Plant Atlas for public use. This Atlas allows users to access location information from over 385,000 vascular plant specimen and observation records in the state of Oregon. The potential applications of such spatial information are...
Premise of study: This research seeks to advance understanding of conditions allowing movement of fungal pathogens among hosts. The family Clavicipitaceae contains fungal pathogens exploiting hosts across three kingdoms of life in a pattern that features multiple interkingdom host shifts among plants, animals, and fungi. The tribe Ustilaginoideae potentially represents...
This dissertation is an attempt at developing a method for the analysis and estimation of the effects of disruptions due to uncertainties. Such uncertainties may result from design changes and engineering drawing delays in large-scale, complex, research and development, or construction projects.
In order to provide management with a simple...
A complete solution, exact to second-order, for wave motion
forced by a hinged-wavemaker of variable-draft is presented. A
solution for a piston type wavemaker is also obtained as a special
case of a hinged-wavemaker with negative infinite draft. The
existing Stokes inviscid theories for mass transport is extended to
include...
As part of its management strategies for wetlands in Oregon, the Division of State Lands sponsored a Local Wetland Inventory for the city of Tillamook. Wetlands delineation,
determination, assessment, and management are the concern of several institutions which worked together to create the 1993 Oregon Freshwater Wetland Assessment Methodology. With...
The Mt. Scott watershed in northern Clackamas County, Oregon is an urban watershed that lies inside the Portland metropolitan urban growth boundary. Urbanization of the watershed began in the early 1970s and has recently accelerated. A landscape level analysis of the urbanization process was combined with the results of a...
Economic theorists have proposed that the problems created
by a Pareto-relevant externality may be solved by market transactions
between the involved parties. These market transactions would allow
realization of the potential gains from trade which characterize a
Pareto-relevant externality. After all potential gains from trade had
been realized, a Pareto-efficient...
