  • Three strategies for tree bucking at the harvest site: consequences for the sawmill

    Creator:
    Acker, Timothy A.
    Abstract:
    The timber shortage in the Pacific Northwest is forcing sawmill owners to improve the competitiveness of their harvesting and processing operations. A computer simulation and financial statement analysis were used to compare the processing efficiency and profitability of three bucking strategies: log cost minimization (traditional 40-foot preferred-length logs); hauling length...

  • The effect of rip-kerf width on 5/4 Ponderosa pine cutting stock yield

    Creator:
    Rahardjo, Susilowati
    Abstract:
    The moulding and millwork industry consumes large quantities of shop grade lumber which is becoming less plentiful and of a lower quality. This fact has compelled industry to explore the use of new technology to increase product yield. One prospect for increasing yield is the application of thin-kerf sawing technology....

  • The effect of edging red alder lumber on cut stock production

    Creator:
    Schott, Kermit A.
    Abstract:
    It has been observed that edging flitches into lumber unnecessarily reduces the yield of cut stock. This research investigated the yield of cut stock from unedged red alder (Alnus rubra) flitches, and compared it to yields attained from boards subjected to a variety of edging strategies: conventional, light-edging, actual, severe...

  • Modeling microarchitecture simulator using object-oriented approach

    Creator:
    Chan, Chung-lun
    Abstract:
    With the success of the CounterDataFlow Pipeline microarchitecture developed by Oregon State University, there is increasing demand for a highly flexible high-level simulator modeling tool to support the further expansions and studies of the Counterflow pipeline processors family. This work examines the implementation of a Java-based execution-driven simulator modeling tool,...

  • Performance and graphics enhancement of the LOGSIM mechanized log harvesting system simulator

    Creator:
    Moss, J. Alexander
    Abstract:
    The focus of this research concentrates on enhancement of the LOGSIM mechanized log harvesting system simulator. Enhancement of software focuses on overall improvement of the user environment as well as improvement of the performance and capabilities of the simulation package. An enhanced version of the front-end interface program is developed...

  • Initial spatial motion of a rigid body on removal of one constraint

    Creator:
    Batra, Ajoy
    Abstract:
    This thesis presents a discussion of motion of a six-legged walking machine following removal of one leg constraint. To take a step, one leg must be lifted and placed at some other position. As soon as the constraint provided by the leg is removed, however the machine begins to fall....

  • Numerical simulation of pressing wood-fiber composites

    Creator:
    Haselein, Clovis R.
    Abstract:
    A model to simulate the dry-process pressing of wood composites is presented. The model uses as its starting point a pre-existing mass and heat transfer model. A number of furnish material properties, including fluid permeability, thermal conductivity, hygroscopicity and rheological parameters, are reviewed and modified for use in the pressing...

  • Multi-Scale, Multi-Physics Reactor Pulse Simulation Method with Macroscopic and Microscopic Feedback Effects

    Creator:
    Zabriskie, Adam X.
    Abstract:
    The Transient Reactor Test facility (TREAT) at Idaho National Laboratory (INL) is a unique reactor capable of stressing test fuel during a power pulse transient. TREAT fuel is composed of high enriched uranium (HEU) heterogeneous fuel; microscopic UO₂ fuel grains with an average radius of 10 μm are randomly distributed...

  • Rendering and Simulation for Tires Rolling on Snow

    Creator:
    Clucas, Alexander
    Abstract:
    Modeling tire-snow interaction is important in designing effective snow tires, which directly affects road safety during wintry weather. Unfortunately, tires have complex tread designs and the physical properties of snow have not been characterized. We employ the Material Point Method (MPM) for simulating a material that mimics the fracturing and...

  • Tsunami Simulation Using OpenSees : Validation of Bridge Response and Exploration of Shallow Water Flow

    Creator:
    Cressman, Luke R.
    Abstract:
    The finite element software framework, OpenSees, has been used by researchers to simulate the response of structural and geotechnical systems to earthquake loading. Implementation of the Particle Finite Element Method (PFEM) has made it possible to simulate hydrodynamic forces through fluid-structure interaction (FSI) in OpenSees. To validate the FSI implementation...
