  • 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...

  • Unsaturated Soils and Foundation Design : Theoretical Considerations for an Effective Stress Framework

    Creator:
    Baker, Josiah D.
    Abstract:
    This study presents the theoretical background necessary to model the bearing capacity of shallow and deep foundations in partially saturated soils. The conventional bearing capacity equations for shallow and deep foundations and the 𝛽-method for deep foundation side resistance have been modified to include the effects of matric suction and...

  • Optimizing the primary forest products supply chain : a multi-objective heuristic approach

    Creator:
    Hamann, Jeff D.
    Abstract:
    This thesis is a collection of four submitted manuscripts that present methods to assist forest ecosystem service managers wanting to develop operational sampling, monitoring, and production plans for a set of specific quantifiable ecosystem services, which are formulated as a series of general multi-objective optimization problems. The problems are solved...

  • Evaluating safety at Oregon‘s isolated, high-speed, signalized intersections

    Creator:
    Kopper, Neil H.
    Abstract:
    Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...

  • Micromixer assisted continuous flow synthesis of nanoparticles of binary compounds and their application

    Creator:
    Palanisamy, Barath
    Abstract:
    In this work, continuous synthesis routes for binary nanoparticles using advantages of microchannel mixing (low diffusion distances and higher mass transfer) and fast heating rates provided by ultrasound induced heating are investigated. In addition, the application of silica nanoparticles in anti-reflective coatings on glass and understanding the structure­ property-performance correlation...

  • Application of GNSS for Vertical Reference Determination

    Creator:
    Kim, Su-Kyung
    Abstract:
    Vertical datum is a reference system used for specifying the elevation of specific points on or near the Earth. Precise and accurate definition and realization of vertical references are, therefore, crucial to ensure consistency between height measurements. The vertical datums can be divided into two categories: 1) vertical geodetic datums...

  • Design and implementation of a heuristic-based decision support system for nurse scheduling

    Creator:
    Sitompul, Darwin
    Abstract:
    A decision support system (DSS) for nurse scheduling in hospitals is developed and implemented on microcomputer. The system includes algorithms and databases for developing weekly work and shift patterns and combining these into working schedules for nurses for a specified time horizon, and interface modules for the user to interact...

  • Forest biomass estimation with hemispherical photography for multiple forest types and various atmospheric conditions

    Creator:
    Clark, Joshua Andrew
    Abstract:
    The importance of accurately identifying inventories of domestic energy, including forest biomass, has increasingly become a priority of the US government and its citizens as the cost of fossil fuels has risen. It is useful to identify which of these resources can be processed and transported at the lowest cost...

  • Assessment of Airborne Light Detection and Ranging (LiDAR) for use in common forest engineering geomatic applications

    Creator:
    Craven, Michael B.
    Abstract:
    Airborne Light Detection and Ranging (LiDAR) has become a popular remote sensing technology to create digital terrain models and provide forest inventory information. However, little research has been done to investigate the accuracy of using airborne LiDAR to perform measurement tasks common to Forest Engineering. This thesis contains two manuscripts...

  • A supply chain model for optimizing fixed and mobile bio-oil refineries on a regional scale

    Creator:
    Mirzaie, Pantea
    Abstract:
    The use of fossil fuels and their related impact on the environment and global warming have encouraged societies to pursue more sustainable and renewable alternatives, e.g., forest-based bio-oil. Thus, a vital need to decrease the level of greenhouse gas emissions and the tendency of nations to reduce their dependency on...
