  • Computational geometry package with fast Voronoi diagram algorithm

    Creator:
    Nave, Jay
    Abstract:
    An interactive Computational geometry package was developed for the purpose of experimenting with geometry problems in the Euclidean plane. The package also contains computer graphics functions to display the result. Application independent functions were developed that are both flexible and general enough for creating new geometry experiments as well as...

  • Finite difference time domain modeling of subwavelength-structured anti-reflective coatings

    Creator:
    Han, Katherine, Han, Hai-Yue, Stack, James, Jr., and Chang, Chih-Hung
    Abstract:
    The finite difference time domain (FDTD) method was used to model anti-reflective properties of a variety of sub-wavelength structures for 300 to 1300 nm input light. Light hitting non-tapered nanostructures exhibited interference patterns similar to thin film anti-reflective coatings (ARCs), increasing the anti-reflective effect at several wavelengths. The lowest reflectance...

  • Monte Carlo Simulations of Structure and Melting Transition of Small Ag Clusters

    Creator:
    Collins, Lee
    Abstract:
    The behavior of small atomics cluster largely depends on their geometry, due to the high ratio of surface atoms to interior atoms. One interesting aspect to study clusters centers around characterizing the transition behavior between nite and bulk materials, where the ratio of surface atoms to interior atoms is very...

  • Geometry of Locomotion

    Creator:
    Ramasamy, Suresh
    Abstract:
    Many animals and robots move through the world by coupling cyclical changes in shape called gaits to an interaction with the environment. Because mobility is an important aspect of such robots, a key metric when evaluating design and performance of mobile robots is the efficiency of their optimal gaits. The...

  • Heat Loss Characterization of NIST-1's Containment Vessel

    Creator:
    Yoshiura, Ramon K.
    Abstract:
    NuScale Power has designed a small modular reactor using natural circulation cooling dependent systems for both steady-state and transient operations. The NuScale Integral Test System (NIST-1) facility was built to supply test data to NuScale Power to verify and validate computer codes for the NuScale Power Mod- ule (NPM) with...

  • Hybrid computational voxelization using the graphics pipeline

    Creator:
    Rauwendaal, Randall
    Abstract:
    This thesis presents an efficient computational voxelization approach that utilizes the graphics pipeline. Our approach is hybrid in that it performs a precise gap-free computational voxelization, employs fixed-function components of the GPU, and utilizes the stages of the graphics pipeline to improve parallelism. This approach makes use of the latest...

  • A Computational Fluid Dynamics Study on the Hydrodynamics for Tandem Plate Configurations under Turbulent Flow

    Creator:
    Gjemso, Jonathan
    Abstract:
    The subject of fluid-structure interactions (FSI) are a matter concerning the design of any element immersed in a fluid. One of the most critical phenomena embedded within the scope of FSI is the creation of vortex-induced vibrations (VIV). These type of vibrations originate in a given body as a result...

  • Computational methods for protein-protein interface prediction

    Creator:
    Tribelhorn, Benjamin
    Abstract:
    Protein-protein interactions underlie all biological processes and are a field of study that has wide implications throughout many other fields including medicine, genetics, biology, and ecology. Proteins are the building blocks and primary actors of life. They work together to accomplish virtually every task within a cell, including, metabolism, signal...

  • Modeling non-Darcy flows in realistic pore-scale proppant geometries

    Creator:
    Trykozko, Anna, Peszynska, Malgorzata, and Dohnalik, Marek
    Abstract:
    The ability to evaluate the effective permeability of proppant packs is useful in predicting the efficiency of hydraulic fracture installations. In this paper we propose a computational approach combining microimaging data from X-ray computed microtomography, the simulations of flow at pore-scale, and an upscaling process which identifies the effective model...

  • Relationships among preservice teachers' conceptions of geometry, conceptions of teaching geometry and classroom practices

    Creator:
    Scholz, Janet Maria
    Abstract:
    Prospective teachers enter teacher education programs with previously formed conceptions of geometry and its teaching. These conceptions help them make sense of new information about teaching, their roles as teachers, and their translation of mathematics into learning activities. The purpose of this study was to investigate the relationships among preservice...
