  • Evaluation of the colonization and biofilm production by Burkholderia pyroccinia FP62 on geranium leaves

    Creator:
    Wallace, Patricia K.
    Abstract:
    The leaf surface is a stark environment for bacterial colonists with limited availability of nutrients, water and protected niches. Despite these limitations, a plethora of bacteria appear to have adapted ways to survive and flourish on leaf surfaces. One mechanism of survival is the formation of biofilms. Biofilms are a...

  • Effects of oil and natural gas development on territory occupancy of ferruginous hawks and golden eagles in Wyoming, USA

    Creator:
    Wallace, Zachary P.
    Abstract:
    Energy development is expanding rapidly across the western US. Negative effects have been documented for some wildlife, but consequences of development are unclear for other taxa, including raptors. We had the opportunity to examine effects of oil and natural gas development on two raptor species of conservation concern, ferruginous hawks...

  • David Foster Wallace's communal middle ground

    Creator:
    Randlemon, Daniel E.
    Abstract:
    Throughout the course of this thesis, I argue that the prose of David Foster Wallace, specifically his posthumously published novel The Pale King, inhabits a middle ground between universal sincerity and the particularized authenticity of postmodern irony. I examine Lionel Trilling's definitions of sincerity and authenticity before moving toward an...

    Creator:
    Tuma, Teresa K. Easterling
    Abstract:
    This collection consists of autobiographical essays which center around my father, my first husband, and my backyard. All of the pieces are recollections, and most occur either from my study inside the house, or from the deck outside, looking at the yard. The Preface is the story of how I...

  • Implications of cougar prey selection and demography on population dynamics of elk in northeast Oregon

    Creator:
    Clark, Darren A.
    Abstract:
    Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...

  • General pole number model for the brushless doubly-fed machine

    Creator:
    Boger, Michael S.
    Abstract:
    The Brush less Doubly-Fed Machine (BDFM) has the potential to be a more cost effective replacement for conventional induction or synchronous machine drives. The BDFM has two stator windings: a power winding and a control winding. An electronic power converter of variable voltage and frequency is connected to the control...

  • Investigation, analysis and design of the linear brushless doubly-fed machine

    Creator:
    Seifkhani, Farroh
    Abstract:
    This thesis covers the efforts of the design, analysis, characteristics, and construction of a Linear Brush less Doubly-Fed Machine (LBDFM), as well as the results of the investigations and comparison with its actual prototype. In recent years, attempts to develop new means of high-speed, efficient transportation have led to considerable...

  • Dynamic modeling, simulation and stability analysis of brushless doubly-fed machines

    Creator:
    Li, Ruqi
    Abstract:
    A brushless doubly-fed machine (BDFM) is a single-frame, self-cascaded induction machine capable of operating in both the induction and the synchronous modes. This thesis presents some important advances concerning dynamic modeling, simulation and analysis of the BDFM. Initially, a two-axis model and its associated parameters are developed and calculated. The...

  • Passively controlled variable-speed generator system

    Creator:
    Bathon, Tobias Siegfried
    Abstract:
    This thesis presents both an analysis and simulations of a passively controlled variable-speed generator system, which can be applied for renewable energy sources such as wind turbines. Parallel connected passive/external resistors and inductors are connected to the slip rings of a wound rotor induction machine to provide an acceptable speed...

  • Design procedure for brushless doubly-fed machine used as a limited speed-range pump drive

    Creator:
    Alajmi, Abdulhadi M.
    Abstract:
    The continuing desire of industry to further improve process efficiency, through tighter control and energy conservation, has prompted users to pay closer attention to Adjustable Speed Drives (ASDs). The conventional ASDs consist of induction or synchronous motors controlled by power electronic controllers through the adjustment of supply frequency and line...
