  • Finite Element and Finite Difference Methods for Maxwell’s Equations in Metamaterials

    Creator:
    Stallcup, Isaac A.
    Abstract:
    In this thesis, we consider Maxwell's Equations and their numerical discretization using finite difference and finite element methods. We first describe Maxwell's equations in linear dielectrics and then present finite difference and finite element methods for this case. We then describe Maxwell's equations in linear metamaterials using the Lorentz and...

  • A Vector–Host Model for Coinfection by Barley/Cereal Yellow Dwarf Viruses

    Creator:
    Leung, Margaret-Rose W.
    Abstract:
    Barley and cereal yellow dwarf viruses (B/CYDV) are a suite of aphid-vectored pathogens that affect diverse host communities, including economically important crops. Coinfection of a single host by multiple strains of B/CYDV can result in elevated virulence, incidence, and transmission rates. We develop a model for a single host, two...

  • Qualitative Analysis of Maxwell-Duffing Models in Nonlinear Optics

    Creator:
    Tro, Sara K.
    Abstract:
    In this thesis we analyze a model for Kerr optical materials consisting of Maxwell's equations along with the dispersive Duffing model. We consider Duffing models with cubic and quintic polynomial nonlinearities. We assume a traveling wave solution to this nonlinear electromagnetic system and analyze it using the theory of dynamical...

  • The Effect of Temperature on the Survival of Chinook Eggs and Fry

    Creator:
    Teose, Maarika
    Abstract:
    Temperature data from above and below the Cougar Dam collected by the U.S. Geological Survey prior to the construction of the temperature control structure was analyzed to determine how the di®ering temperature regimes a®ect the growth and survival of threatened spring- run Chinook salmon. An ARIMA time-series model was used...

  • Numerical Simulation of a Thouless Pump

    Creator:
    Wall, Bryce
    Abstract:
    At the macroscopic scale, we have pumps that use the classical laws of physics to move liquids at a well defined rate. In the microscopic world, physicists are exploring pumps that make use of quantum mechanical behavior to build analogous pumps for quantum particles. The importance of such “quantum pumps”...

  • Music Generation and Evaluation Using R

    Creator:
    Lanz, Andrea L.
    Abstract:
    The main goal of this project is to implement an algorithmic music composition procedure and present all procedures and results in a reproducible fashion by creating a web application produced by R. To approach the implementation of the algorithmic composition of music, we start by exploring various models, but ultimately...

  • Modeling of Power Efficiency in a Magnetohydrodynamic Generator

    Creator:
    Redle, Michael T.
    Abstract:
    The introduction of an Magnetohydrodynamic (MHD) generator in coal or natural gas energy plants could significantly increase the efficiency by converting kinetic and thermal energy of the combustion exhaust to electrical energy by the generation of a Faraday and Hall current. The traditional MHD system was transformed into a simplified...

  • Surface patterning of biofilm : A toolbox study to detect microbial metabolites

    Creator:
    Nguyen, Kristine
    Abstract:
    Surface patterning of bacterial biofilm provides an opportunity to understand the microbial metabolic exchange between bacterial species. By using various techniques, one can put different bacterial species in close proximity and study their interaction by using various assay kits and analytical techniques. In this study, surface patterning of Pseudomonas aeruginosa...

  • Development of micro-wire solid-state sensors for the real-time detection of metabolites at the Streptococcus mutans biofilm-biomaterial interface

    Creator:
    Aponso, Savinda
    Abstract:
    We have developed a 100 m diameter solid-state potentiometric pH sensor to study the bacterial metabolism at the biofilm-biomaterial interface in real-time. The newly developed agar-coated pH sensor is both highly resistant to biofouling and stable, with a drift of 1 mV/h in physiological conditions. We used multiwall carbon nanotubes...
