There is a new possibility of generating deep ultraviolet laser radiation from a solid-state source. With recent advances in material development, a new nonlinear optical crystal provides a greater damage threshold than current materials making higher conversion efficiencies possible.
This thesis examines the possibility of using this crystal to generate...
Pacific lampreys (Lampetra tridentata) have declined in abundance in the Columbia River Basin. Although, the reasons for the decline are unclear, we suggest that development of hydroelectric dams and habitat alterations in tributaries as the main causes. The available knowledge of life history of Pacific lampreys and status from dam...
The application of the collinearity solution by resection of the interior and exterior
orientation parameters of historical photographs is investigated. The spatial coordinates of seven
or more identifiable control points in the field of view of an historical photograph, combined
with image coordinates of the control point images, allow solution...
The purpose of this thesis is to explore the design of a multimedia extension Instruction Set Architecture (ISA) for a reconfigurable processor. An Extendable Multimedia Module (EM3) was designed as an optional module for X32V. X32V is a prototype configurable processor simulator developed at Oregon State University by John Mark...
General purpose computer systems have seen increased performance potential through the parallel processing capabilities of multicore processors. Yet this potential performance can only be attained through parallel applications, thus forcing software developers to rethink how everyday applications are designed. The most readily form of Thread Level Parallelism (TLP) within any...
A stalagmite (sample OCNM8-02A) collected from Oregon Caves National Monument (OCNM) was sampled for stable isotope ratios in order to develop a record of Pacific Northwest climate history. Nine U-series dates indicate that the record spans the time period - 13.5 - 9.5 ka. The stalagmite growth rate varied from...
This document is the 1998 annual progress report for studies of Pacific lampreys
(Lampetra tridentata) conducted by the Confederated Tribes of the Umatilla Indian
Reservation (CTUIR), Columbia River Inter-Tribal Fish Commission, and University of
Minnesota (U of M). Bonneville Power Administration (BPA) funded activities through
Project 94-026.
The Pacific Lamprey...
Lateral heel wedge orthotics are designed to reduce medial tibiofemoral joint loading and pain in patients with knee osteoarthritis (OA). To date, the efficacy of long-term lateral heel wedge orthotics use among OA patients has not been determined. This study evaluated the extent to which lateral heel wedge orthotics reduced...
This study examined daily streamflow response over up to four decades in northwest conifer forest and eastern deciduous forest sites in the United States. We used novel methods to analyze daily observations of climate and streamflow spanning more than 900 basin years of record at 14 treated/control basin pairs where...
We analyzed the sedimentological characteristics and magnetic properties of cores from the three basins of Clear Lake, California, USA, to assess the depositional response to a series of land use changes that occurred in the watershed over the 20th century. Results indicate that distinct and abrupt shifts in particle size,...
