  • 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...

  • Estimating spatial changes in acoustic velocity in felled Douglas-fir stems

    Creator:
    Dowding, Bodie
    Abstract:
    To compete with other building materials, the wood products industry must find a way to increase value and lower costs. Wood stiffness is important for most wood uses. Value can be increased and costs can be lowered by sorting logs for stiffness in the woods using acoustic devices mounted on...

  • 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...
