  • 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...

  • Design and implementation of a decision support framework for evaluating manufacturing alternatives

    Creator:
    Saleh, Budiman
    Abstract:
    To be competitive in domestic and international markets, manufacturing management is routinely faced with the decision to automate or replace existing production facilities with advanced manufacturing technologies. Installation of advanced manufacturing technologies requires high capital investment, and there is much evidence to suggest that automation for automation's sake has proven...

  • An efficient high-performance computing based three-dimensional numerical wave basin model for the design of fluid-structure interaction experiments

    Creator:
    Nimmala, Seshu B.
    Abstract:
    Fluid-structure interaction (FSI) is an interesting and challenging interdisciplinary area comprised of fields such as engineering- fluids/structures/solids, computational science, and mathematics. FSI has several practical engineering applications such as the design of coastal infrastructure (such as bridges, levees) subjected to harsh environments from natural forces such as tsunamis, storm surges,...

  • Optimal irrigation management : a framework, model, and application for optimizing irrigation when supplies are limited

    Creator:
    Hillyer, Charles C.
    Abstract:
    Many regions in North America are experiencing water shortages, and these conditions are expected to worsen. The next generation of irrigation scheduling applications must therefore be capable of providing operational advice in support of deficit irrigation strategies. However, the theoretical, technical, and practical challenges associated with deficit irrigation scheduling are...

  • Behavior graphs for data-driven animation of 3d characters

    Creator:
    Srinivasan, Madhusudhanan
    Abstract:
    In this dissertation, we present a user-in-the-loop method for the design of an interactive motion data structure that benefits from the advantages of both motion graphs and blend-based techniques. Our novel approach automatically analyzes a traditional motion graph built from labeled motion clips. The result is a more condensed, coarser...

  • Modeling studies of the coastal circulation off northern California

    Creator:
    Pullen, Julie D.
    Abstract:
    By implementing a series of mass-conserving nested high-resolution models down to approximately 1 km resolution that have realistic bathymetry, coastline, wind forcing and river run-off, the winter 1996-1997 shelf flow near Cape Mendocino, California, is simulated and compared with available observations from the Strata Formation on Margins (STRATAFORM) marine geology...

  • Large Ensembles of Regional Climate Simulations over the western United States

    Creator:
    Li, Sihan
    Abstract:
    Large ensembles of regional climate simulations were generated from the weather@home distributed volunteer computing project over the western US domain. Weather@home uses the U.K. Met Office Hadley Centre’s regional climate model HadRM3P (~0.22°) nested within the atmospheric global model HadAM3P (1.875 longitude° by 1.25 latitude°). Simulations from HadRM3P were evaluated...

  • Dynamic modeling and mitigation of cascading failure in power systems

    Creator:
    Song, Jiajia
    Abstract:
    Recent blackout events consistently show that a variety of mechanisms are involved in cascading outages. These cascading mechanisms are irregularly modeled and validated within the existing literature and industry practices. Understanding the relative significance of these different mechanisms is important for choosing which one(s) needs to be modeled for specific...

  • The Development and Evaluation of the Tennis Shirt Pattern for a Wheelchair Tennis Player in a CAD Program

    Creator:
    Jin, HeeJae
    Abstract:
    This study was to develop and evaluate a shirt pattern for a wheelchair tennis player to improve comfort using reducing garment strain using a CAD program. For that, seven body movements related to garment strain during play were analyzed. In order to develop a pattern, a morphological matrix was used...

  • Quantified PIRT and uncertainty quantification for computer code validation

    Creator:
    Luo, Hu
    Abstract:
    This study is intended to investigate and propose a systematic method for uncertainty quantification for the computer code validation application. Uncertainty quantification has gained more and more attentions in recent years. U.S. Nuclear Regulatory Commission (NRC) requires the use of realistic best estimate (BE) computer code to follow the rigorous...
