  • An economic analysis of land prices of mountainous grazing land in eastern Oregon

    Creator:
    Winter, John R.
    Abstract:
    The "unusual" behavior of agricultural land prices is the subject of considerable debate and controversy and is the object of this research. There is little doubt that land prices have been increasing steadily since 1959 and dramatically throughout the decade of the 1970's. However, there is widespread disagreement among economists,...

  • Grass seed producers in the Willamette Valley, An econometric analysis of risk attitudes among grass seed producers in the Willamette Valley

    Creator:
    Ahmed, Awadelkarim Hamid
    Abstract:
    The present increasing need for the development of empirical hypotheses that explain the decisionmakers' behavior towards risk is to provide an understanding of the framework within which an industry operates. Such hypotheses could facilitate the implementation of policies designed to solve problems identified within an industry and could also provide...

  • Computer vision for geometrical analysis of bridge gusset plates

    Creator:
    Varakantham, Shravya
    Abstract:
    Gusset plates are an important component of bridges. They are thick sheets of steel that join steel members together using fasteners and also strengthen their joint. Transportation agencies regularly evaluate and rate their inventories of gusset plate connections using visual inspection, which is very costly. To address this issue, we...

  • Managing bug reports in free/open source software (FOSS) communities

    Creator:
    Mohan, Nitin
    Abstract:
    Free/Open Source Software (FOSS) communities often use open bug reporting to allow users to participate by reporting bugs. This practice can lead to more duplicate reports, as inexperienced users can be less rigorous about researching existing bug reports. The purpose of this research is to determine the extent of this...

  • Topological analysis, visualization, and design of vector fields on surfaces

    Creator:
    Chen, Guoning
    Abstract:
    Analysis, visualization, and design of vector fields on surfaces have a wide variety of major applications in both scientific visualization and computer graphics. On the one hand, analysis and visualization of vector fields provide critical insights to the flow data produced from simulation or experiments of various engineering processes. On...

  • Using provenance to aid document re-finding

    Creator:
    Lonsdale, Heather
    Abstract:
    In the field of Human-Computer Interaction, provenance refers to the complete history and genealogy of a document. Provenance can be useful in identifying related resources, such as different versions of the same document or resources used in the creation of a new document. Though methods of provenance collection and applications...

  • Classification of motion capture sequences

    Creator:
    Maniar, Dharin Haresh
    Abstract:
    Motion capture data is a digital representation of the complex temporal structure of human motion. Motion capture is widely used for data-driven animation in sports,medicine and entertainment, because of its ability to capture complex and realistic motions. Due to its efficiency and cost, methods for reusing collections of motion capture...

  • The biochemical oxygen demand of Douglas-fir needles and twigs, western hemlock needles and red alder leaves in stream water

    Creator:
    Ponce, Stanley L.
    Abstract:
    Field studies indicate that accumulation of finely divided organic debris in the channels of mountain streams after clearcutting may be responsible for subsequent reduction in the dissolved oxygen concentration. The purpose of this study was to quantify the biochemical oxygen demand (BOD) of Douglas-fir needles and twigs, western hemlock needles...

  • Investigating the Potential of Slow Release Nitrogen Fertilizer to Increase Agricultural Nitrogen Management Efficiency for Tall Fescue in the Southern Willamette Valley

    Creator:
    Derksen, Jacob Z.
    Abstract:
    Nitrogen (N) fertilizer application can promote nitrate leaching below the rooting zone and into groundwater drinking water sources in many agricultural settings. The proper management of N application can minimize non-point source nitrate pollution to groundwater. This study examines the potential for enhanced efficiency fertilizers, specifically urea treated with a...

  • The choice calculus : a formal language of variation

    Creator:
    Walkingshaw, Eric
    Abstract:
    In this thesis I present the choice calculus, a formal language for representing variation in software and other structured artifacts. The choice calculus is intended to support variation research in a way similar to the lambda calculus in programming language research. Specifically, it provides a simple formal basis for presenting,...
