Geology (Geo, Geos = the earth) is a science that deals with the history of the earth and its life as recorded in the rocks. Geology utilizes the principles of physics, chemistry, astronomy, zoology, botany, and others in its studies. There are many specialties or fields of study in geology,...
Ecosystem management has become an increasingly mainstream paradigm for natural
resource management. Nowhere is this more evident than on the public and private forestland
of the Pacific Northwest. While ecosystem management has become a widely
accepted principle of resource management, substantial questions remain about its
implementation. A case in point...
Coarse woody debris (CWD) decomposition in the Russian boreal forests of the southern taiga zone was studied at four sites located near St. Petersburg in Northwestern Russia, Krasnoyarsk in Eastern Siberia, lrkutsk in the Baikal region, and Khabarovsk in the Russian Far East. This study was part of a broader...
The harmonic problem in power systems is gaining more attention as incidences correlated with harmonics increase. Conventional passive filtering techniques for harmonic mitigation have inherent problems, and purely active filters have the disadvantages of higher costs and ratings. Hybrid active filters inherit the efficiency of passive filters and the improved...
Riparian areas are an integral component of fluvial ecosystems. The management of Oregon's riparian areas has come under greater scrutiny since that latest revision of the Oregon Forest Practices Act (1994). Many riparian areas lie within forested areas. Riparian management issues such as anadromous fish population decline and large woody...
In the highly competitive animal protein market, seafood faces increasing pressure to improve and standardize product quality. While there is general consensus that quality can be improved for many seafood products, there is little agreement on the types and levels of characteristics that should define "quality." This is a fundamental...

The purpose of this study was to describe the presidential search process at a
newly created community college and to learn how that process reflected the
emerging organizational culture. A single research question guided the inquiry: How
did the presidential search process at a newly created community college reflect the...
Power quality has become an important concern to both electric utilities and
end users due to the increased use of non-linear loads in modem power systems
over the past decade. Nonlinear loads inject harmonics into the power system and
thus may lead to poor power quality and lower power factor....
Literary and feminist theory have recently begun to recognize William Shakespeare's character of Juliet as a possible feminist heroine, but communicating this interpretation on film will be complicated. Not only will the film need to deal with the issues of adaptation that come with moving any play onto film, but...
This document investigates, justifies, designs, and simulates the application of a fuzzy logic controller/optimizer in a sawmill bucking system application that is the first production station where stems coming from the mountains are processed in a sawmill. One of the areas of success in the application of fuzzy logic is...
The 14-km long Netarts Littoral Cell, located on the northern Oregon coast, experienced episodic erosion as a result of the severe 1997-98 El Nino and 1998-99 La Nina. The erosion events led to the development of a unique partnership bridging scientists, stakeholders, and various planning agencies. To address these erosion...
Wireless networking equipment was installed on three research vessels and at three shore stations during the 1998 Thin Layers Experiment in East Sound, Washington. This wireless network provided high-speed data communication between scientists on separate vessels and permitted rapid transfer of data from vessels and from moored instruments to a...
This thesis presents a hydrogeologic study of the Parrett Mountain Region,
located approximately 20 miles south of Portland, Oregon. The aim of the study was
to investigate the impacts of Columbia River Basalt on the regional groundwater
system, to expand our understanding of flow through fractured basalt, to improve
management...
The main purpose of this project is to describe the hydrologic characteristics, with and without
regulation by dams, of the Coast and Middle Forks of the Willamette River, including the
floodplain, from the confluence to approximately eight miles upstream. The research is intended
to assess the future potential of the...
This study described how and why a Korean elementary teacher taught mathematics as he did. Specifically, the study sought to describe his beliefs about the teaching and learning of mathematics and relate them to patterns of classroom interaction and norms.
An ethnographic inquiry guided the study of one third grade...
In the context of forest products, a cutting order is a list of dimension parts along with demanded quantities. The cutting-order problem is to minimize the total cost of filling the cutting order from a given lumber grade (or grades). Lumber of a given grade is supplied to the production...
We present a meta-model as a process maturity framework that can be effectively used to
identify the key practices to initiate and sustain a software process improvement effort
focused on a single process area. Our approach moves away from the overall software
development process and computation of maturity levels and...
Unrelated parallel machines are machines that perform the same function but have
different capacity or capability. Thus, the processing time of each job would be different
on machines of different types. The scheduling environment considered is dynamic in
both job release time and machine availability. Additionally, each job considered can...
Although there has been research into ways to design spreadsheet systems to improve the processes of creating new spreadsheets and of understanding existing ones, little attention has been given to helping users of these environments test their spreadsheets. To help address this need, we introduce two visual approaches to testing...
The main result of this written dissertation is a mathematical solution to the problem of multiplex recording for high performance tandem time-of-flight mass spectrometry. The prescription is to use a time-lag accelerator in the second stage to match the ion optical properties of the decay fragments to the requirements of...
Since their discovery in 1977, hydrothermal vent communities have offered scientists
a unique glimpse into a world that is supported primarily by chemically derived
energy rather than direct energy from the sun. Furthermore, studies of hydrothermal
vent ecosystems have introduced scientists to amazing animals that have successfully
adapted to living...
Lake Kinneret is Israel's only fresh water lake (unless you count the Dead Sea). It spans roughly 20km from north to south, and about 12km at its widest east west extent. It is not quite 50m deep at its deepest point. In late spring, the lake stratifies significantly and remains...
The Mount Fubilan Intrusion is part of a geologically young hypabyssal stock in the Star Mountains of Papua New Guinea. This stock was mapped as the Ok Tedi Intrusive Complex and divided into four separate bodies: the Mount Fubilan, Sydney Intrusion, Kalgoorlie, and Ningi Intrusions. Hydrothermal fluids caused alteration of...
El Niflo and La Nifia are oceanographic and atmospheric phenomena that have been
catalogued for well over a centuly. In El Nifio years, Peru's otherwise thy west coast is
subjected to torrential rainfall. Higher ocean temperatures off the coast are deemed the
culprit. Attempts to quantify this began in the...
This paper introduces the even-odd POMDP, an approximation to POMDPs in which the world is assumed to be fully observable every other time step. The even-odd POMDP can be converted into an equivalent MDP, the

The implementation of concurrent engineering into many large
companies has greatly improved their product development processes.
These companies have seen significant gains in quality and customer
satisfaction with reduced product costs, defects, and time-to-market
(Lake, 1992). Many large companies have successfully employed this
relatively new product development philosophy. However, smaller...
Oregon's estuarine wetland landscapes have been changed, especially since the nineteenth century, by diking, dredging, fills, and other alterations. These alterations have removed wetlands from the estuaries, and with them, have removed wetland functions. Currently, efforts are being made to restore estuarine wetlands. The first step in
selecting a site...
