  • A method for approximating distributions of mechanical properties for structural lumber

    Creator:
    Fernandez, Virgilio Asuncion
    Abstract:
    The present method of design for walls does not accurately predict the strength and stiffness of walls because load sharing and composite action are not taken into consideration. This results in the use of higher strength materials and walls which are overdesigned. A new method of design for walls using...

  • A mathematical model for optimum timber allocation

    Creator:
    Bengston, Steven John
    Abstract:
    Operations research is concerned with the science of decision and uses mathematical models to aid in making these decisions. In this thesis operations research is used in connection with the lumber industry. The problem of concern has to do with a lumber company that is unable to supply the mill...

  • Numerical simulation of wood drying

    Creator:
    Berberovic, Adin
    Abstract:
    A mathematical and then a numerical model were developed for simulating a convective batch lumber drying process. The model incorporates mass and heat transfer relationships within the lumber stack, as well as thermodynamic properties of the wood and drying air. It takes into account a change of air properties along...

  • Development of a posture prediction model

    Creator:
    Dendamrongvit, Thidarat
    Abstract:
    Biomechanical models have been used in designing human work environments to evaluate potential risks to workers before a work environment is constructed. In order for work environments to be modeled correctly, most biomechanical models require as input, an accurate body posture of the worker. This information can be obtained by,...

  • Modified limiting dilution analysis : a mathematical model with biological interpretation

    Creator:
    Maier, Stefan H.
    Abstract:
    A mathematical model of Limiting Dilution Analysis for two limiting parameters is presented and investigated. Limiting Dilution Analysis is a microbiological cell assay developed for immunological application. In the given case we deal with the interaction between B lymphocytes, macrophage derived factor and T-independent antigens. The state of the art...

  • Advanced numerical modeling of the Lorentz mixing process

    Creator:
    Hager, Michael B.
    Abstract:
    There are numerous techniques for improving the mixing of fuel and oxidant species. However, many of these methods cannot be applied to combustion systems due to material limitations. A means of mixing the reacting species without physically invading the flow stream is therefore desired. In this work, induced electromagnetic forces...

  • A "mildly inconsistent" method for accelerating upstream corner balance transport

    Creator:
    Gulick, John C.
    Abstract:
    A new method for accelerating the Upstream Corner Balance (UCB) discretization of the equation of transfer is introduced. The inconsistent acceleration equations for the UCB discretization are derived by applying the "Modified 4-Step" diffusion synthetic acceleration technique not to the UCB discretization, but instead to the simple corner balance (SCB)...

  • Tracer experiments in a non-uniform porous medium : implications of diffusive mass transfer on the late-time breakthrough behavior

    Creator:
    Freiherr von Schwerin, Claudius
    Abstract:
    Mass transfer processes were evaluated in an artificial, non-uniform porous medium with a power law distribution of diffusion rate coefficients obtained from physical characterization of solute and porous medium. Breakthrough curves of several pulse experiments conducted at different velocities were compared (1) to analytical expressions for concentrations at mass transfer...
