  • Tensor Field Design and Analysis for Applications in Computer Graphics and Scientific Visualization

    Creator:
    Palacios, Jonathan
    Abstract:
    Many applications in computer graphics and geometry processing rely on the ability to locally orient 2D and 3D entities on a surface, or inside a volume, such as the sinusoidal kernels in Gabor noise, the color and geometry textures in pattern synthesis, and the finite elements in remeshing. In these...

  • Submerged jet impingement boiling thermal management

    Creator:
    Cardenas, Ruander
    Abstract:
    Technologies such as avionics and power electronics are driving the demand for thermal management schemes towards high heat fluxes and low surface temperatures. Typically, these applications require the dissipation of heat fluxes in the rage of 100-1000 W/cm² while maintaining surface temperatures lower than about 85 °C. Phase-change heat transfer...

  • Local Accessibility of Objective, Classical Reality

    Creator:
    Kincaid, Joshua J.
    Abstract:
    The fact that measuring a quantum system reduces it to apparently classical behavior, eliminating the interference patterns that are a hallmark of quantumness, cries out for an explanation. That explanation has been provided by the recognition of decoherence,whereby the interference is destroyed by the very interaction that acquires information.We begin...

  • Level structure of ¹⁵²Gd populated in ¹⁵²Tb β decay

    Creator:
    Stapels, Christopher John
    Abstract:
    As part of a research program to study the transitional region of N=88 isotones, ¹⁵²Tb was produced by the reaction ¹⁵¹Eu(α,3n)¹⁵²Tb in the 88" cyclotron located at LBNL. Gamma-ray spectroscopy of the radiation emitted from excited ¹⁵²Gd following the β⁺ decay of ¹⁵²Tb has been performed using an array of...

  • An extension of the quantum theory of scattering to the non-asymptotic regime using Bohmian trajectories

    Creator:
    Stenson, Jared R.
    Abstract:
    Quantum mechanics provides a conventional theory of scattering that is limited in at least two ways: it focuses exclusively on the asymptotic regime and, in a more general sense characteristic of all quantum descriptions, provides no concrete account of individual particle evolution in spacetime. This is particularly true during the...

  • Computational nanooptics in hyperbolic metamaterials and plasmonic structures

    Creator:
    Thongrattanasiri, Sukosin
    Abstract:
    This dissertation concerns several problems in the fields of light interaction with nanostructured media, metamaterials, and plasmonics. We present a technique capable of extending operational bandwidth of hyperbolic metamaterials based on interleaved highly-doped InGaAs and undoped AlInAs multilayer stacks. The experimental results confirm theoretical predictions, exhibiting broadband negative refraction response...

  • Electromagnetic properties of anisotropic plasmonic metamaterials

    Creator:
    Elser, Justin Lee
    Abstract:
    In this dissertation we study the electromagnetic properties of plasmonic metamaterials. We develop an analytical description to solve the fundamental problem of free-space scattering in planar plasmonic systems by utilizing anisotropic metamaterials. We show with exact numerical simulations that these manufactured materials do completely eliminate the scattering, and even in...

  • Nonlinear Terahertz Spectroscopy and imaging of Carbon Nanomaterials

    Creator:
    Lee, Byounghwak
    Abstract:
    This dissertation presents nonlinear terahertz (THz) properties of carbon nanomaterials investigated by time-resolved high-field THz spectroscopy. In order to determine THz characteristics of nanomaterials, we performed THz power spectrum measurement, THz raster imaging, THz time-domain spectroscopy (THz-TDS) and time-resolved pump-probe experiment on two different types of single layer graphene and...

  • A moving boundary model of calcium alginate gel formation and the estimation of diffusion and mass transfer coefficients

    Creator:
    Inoue, Shawna K.
    Abstract:
    Calcium alginate gels are widely used in the biotechnology, food, and pharmaceutical industries for cell immobilization, food additives, and controlling the release of therapeutic agents. Different gelation conditions can lead to different gel structures which affects the diffusion of solutes in gels, thus mathematical models were developed to describe diffusion...
