  • In-forest log segregation based on acoustic measurement of wood stiffness

    Creator:
    Amishev, Dzhamal Y.
    Abstract:
    To remain competitive, the forest products industry needs to look for new and innovative processes and technologies to not only reduce costs but also to recover more value through the entire seedling-to-customer forest products supply chain. It is well recognized that measuring wood properties of logs in real time during...

  • Wood properties and use of sensor technology to improve optimal bucking and value recovery of Douglas-fir

    Creator:
    Acuna, Mauricio A.
    Abstract:
    There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...

  • Evaluation of six tools for estimating woody biomass moisture content

    Creator:
    Becerra Ochoa, Fernando Amador
    Abstract:
    Woody biomass transportation costs and market values/costs are strongly correlated with the woody biomass moisture content. Properly managing moisture content can potentially lead to economic and environmental advantages in biomass energy markets. Good management requires accurate moisture content measurements. Therefore, availability of accurate, precise, reliable, and efficient tools to assess...

  • Evaluation of a prototype NIR system for Douglas-fir wood density estimation

    Creator:
    Belart Lengerich, Maria Francisca
    Abstract:
    Forest products companies in the U.S. face vigorous competition from other wood producers around the world and other industries (steel, aluminum, plastics, composites). To be competitive, forest companies need to control costs, sort and allocate logs to the most appropriate markets, and recover more value at time of harvest. Interest...

  • Municipal water source turbidities following timber harvest and road construction in western Oregon

    Creator:
    Grizzel, Jeffrey D.
    Abstract:
    Many municipalities throughout western Oregon rely upon forested watersheds as a source for domestic water supply. These watersheds are commonly managed by state or federal agencies or private corporations for timber production. Activities related to forest management within municipal watersheds have the potential to adversely affect water quality. Timber harvesting...

  • Spatially-explicit prediction of recoverable harvesting residues

    Creator:
    Schmidt, Christian F. W.
    Abstract:
    In order to decide whether or not to develop biomass energy facilities and where to best locate them, developers and investors need accurate assessments of fuel supply. This includes information about the distribution and concentration of fuel throughout the assessment area, the quality of fuel (form, moisture content, contaminant content,...
