Historically the U.S. Forest Service has used uncorrected
aerial photographs to delineate proposed and past management
activities on the land base it manages. Transferring a boundary
from an image not planimetrically correct to a planimetrically
corrected image introduces errors. Positional accuracy of
boundaries affects the number of acres the Forest...
The Queen Charlotte Fault system is a segment of the North America - Pacific
plate boundary. From 45 Ma - 5 Ma, plate motion has been primarily translational.
Since 5 Ma, transpression has been the dominant mode of interaction. The plate
boundary west of the Queen Charlotte Islands is characterized...
Alternating-current thin-film electroluminescent (ACTFEL) devices are metal-insulator-semiconductorinsulator-
metal (MISIM) structures which emit light under high field, pulsed excitation. One aspect of ACTFEL operation that is not well understood is the aging of such devices with operating time. One of the primary goals of
this thesis is to characterize the kinetics...
The focus of this research was to examine the relationship between the Oregon secondary agricultural education teachers’ level of computer-based technology integration, perceptions of barriers to computer-based technology integration, and learning style preferences. Additionally the correlational analysis of the level of computer-based technology integration and the following demographic variables was...
Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...
Hop (Humulus lupulus L. var lupulus) is a plant of great cultural significance, used as a medicinal herb for thousands of years, and for flavor and as a preservative in brewing beer. Studies of the medicinal effects of the unique compounds produced by hop have led to interest from the...
The purpose of this qualitative study was to describe how novice students solved computer programming problems in a beginning college level computer science (CS) course with an introduction to object-oriented programming (OOP) and what knowledge they obtained about OOP and computer problem solving (CPS) as a result of their experiences....
The goal of this phase of the study was to develop a model of the Tualatin River incorporating Scoggins Creek and Hagg Lake. This tool will be used in conjunction with a hydrologic model, the EPA HSPF model (Johnson, Imhoff, and Kittle, 1984), to analyze management strategies to improve water...
This thesis examines prehistoric land use patterns of the entire North Santiam subbasin, located on the western slopes of the Oregon Cascade Range. The objective of this analysis is three-fold: 1) to contribute to reconstructing the cultural chronology of the area; 2) to address the use of raw material by...
