  • Candidate Causes, Consequences, and Estimation of Individual Diet Specialization

    Creator:
    Coblentz, Kyle E.
    Abstract:
    Diet variation among individuals within populations is widespread. Often diet differences among individuals are attributable to obvious differences among individuals such as age, sex, or morphology. However, growing evidence suggests that individual diet variation is also common among seemingly identical individuals within populations. This phenomenon has been termed individual diet...

  • Generalized Preconditioning to Accelerate Simulations with Large Multiphase Chemical Kinetics Models

    Creator:
    Walker, Anthony S.
    Abstract:
    Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...

  • Assessing Mass Diffusion Modeling in Premixed Flames

    Creator:
    Fillo, Aaron J.
    Abstract:
    Implementing multicomponent diffusion in numerical combustion studies is computationally expensive due to the challenges involved in computing diffusion coefficients. As a result, mixture-averaged diffusion treatments or simpler methods are used to avoid these costs. However, the accuracy and appropriateness of the mixture-averaged diffusion model has not been verified for three-dimensional...

  • Computational Modeling of Smoldering Combustion in Wildland Fuels

    Creator:
    Jayasuriya, Waduge Jayani A.
    Abstract:
    Smoldering combustion in wildland fires is a critical phenomenon that needs in-depth study because it can initiate with weaker ignition sources, can persist for long periods, is difficult to suppress, and can transit to flaming combustion. Cellulose, hemicellulose, and lignin are the major organic constituents within biomass, in varying proportions...

  • Status and habitat use of Columbian white-tailed deer in Douglas County, Oregon

    Creator:
    Smith, Winston Paul
    Abstract:
    A study conducted May 1978-December 1980 determined that the present geographic range of Columbian white-tailed deer, Odocoileus virginianus leucurus, (CWTD) in Douglas County, Oregon encompassed 1199km2. The area was predominately a Quercus woodland community, typical of the Interior Valley Zone of western Oregon. The CWTD distribution was not contiguous throughout...

  • Ecology of feral pigs on Santa Catalina Island

    Creator:
    Baber, Daniel W.
    Abstract:
    A feral pig population on Santa Catalina Island, California, was studied for 17 months beginning in July 1980. Density was estimated to be 21 to 34 pigs/km² (95% confidence interval) using capture-recapture techniques. Dry season home ranges determined from radio-telemetry data were small and differed significantly between boars and sows....

  • Advantages of habitat selection and sexual segregation in mule and white-tailed deer

    Creator:
    Main, Martin Benjamin
    Abstract:
    I studied sexual segregation in mule deer (Odocoileus hemionus) and white-tailed deer (Q. virginianus) in different environments and at different population densities to test the hypothesis that sexual segregation occurs in ungulates as the result of different reproductive strategies; females select habitat and behave in manners primarily designed to promote...

  • Autonomous Sensor Systems For Wind Turbine Blade Collision Detection

    Creator:
    Clocker, Kyle
    Abstract:
    Wind turbines serve an increasing proportion of total energy generation, with expanded onshore and offshore installations proceeding worldwide. Continued construction, expansion, and operation of wind energy installations must be managed in conjunction with effects on local and migratory wildlife, specifically bird and bat species that may be affected by wind...

  • Electronic and Optical Properties of Defects in Amorphous Oxide and Transition Metal Dichalcogenide Semiconductors

    Creator:
    Vogt, Kyle
    Abstract:
    The optical and electronic properties of amorphous oxide thin films depend crucially on chemical composition, and deposition process variations which give rise to sub-gap defect states. Consequently, there is a need for a reliable, high-throughput method to extract sub-gap defect densities of states in amorphous oxide thin films. We present...

  • Characterization of high temperature fatigue mechanisms in Haynes 282 nickel based superalloy

    Creator:
    Rozman, Kyle A.
    Abstract:
    Electric power needs will only grow over the next decades as more humans ascend from poverty into the middle class. Currently, the majority of electric power is generated by burning fossil fuels. To help mitigate the undesirable effects of burning fossil fuels research is being done to increase the efficiency...
