  • An investigation of the feasibility of a process-intensified differential temperature water-gas shift reactor with integrated Pt/Al2O3 catalyst

    Creator:
    Hu, Kathy Q.
    Abstract:
    There has been serious interest in hydrogen as a source of energy in the United States due to its capability of delivering a sustainable, carbon-free energy future. Currently, most hydrogen in the United States is produced via the steam methane reforming of natural gas, which converts methane to hydrogen through...

  • Hybrid electric vehicle dc-bus converter harmonics

    Creator:
    Mills-Price, Michael A.
    Abstract:
    As more advanced hybrid electric vehicles begin emerging onto the commercial market, design algorithms for their control become increasingly more complicated. One major hurdle for designers is the mitigation and control of the created high frequency harmonics caused from switching the dc voltage into an ac voltage by use of...

  • End-to-end network throughput enhancement through physical-layer network coding

    Creator:
    Maeouf, Sofean Ahmed
    Abstract:
    Physical-Layer Network Coding (PNC) is a promising technique that has great potentials for improving the achievable data rates of end-to-end flows through higher packet transmission rates, thereby increasing the overall network throughput. In this thesis, we study the performance of the PNC transmission techniques for unidirectional end-to-end flows in multi-hop...

  • Clearing bubble blockages in micro channels using a model predictive controller

    Creator:
    Patton, Chris
    Abstract:
    Micro scale systems are being utilized in a wide variety of chemical, biological and heat exchanger applications, but suffer from the development of vapor bubbles inside the microchannels due to convective boiling, leading to decreases in system performance. In this work, a simulation-based control strategy is employed to eliminate flow...

  • Differential gene expression in the pregnant bovine corpus luteum during maternal recognition of pregnancy

    Creator:
    DuBay, Kristi M.
    Abstract:
    Interferon tau (IFN-τ) is the pregnancy recognition signal secreted by the trophectodermal cells of the developing bovine embryo that prevents luteolysis and maintains critical progesterone production. Recent evidence has suggested in addition to the mechanism of action identified in the uterus, there may be a direct effect of IFN-τ on...

  • Reliability and hot-electron effects in analog and mixed-mode circuits

    Creator:
    Ge, David Ying
    Abstract:
    Reliability of sub-micron analog circuits is directly related to impact ionization and the subsequent changes in threshold voltage and drain current of n-MOSFET devices. This thesis presents theory of the hot-electron effects on the device characteristics and circuit performance, explores several approaches to improve performance at both the device and...

  • Strategies for Altering Energy Flux in Thalassiosira pseudonana Elucidated by Transcriptomics

    Creator:
    Pombrol, Michelle
    Abstract:
    Diatoms play a major role in ocean biogeochemical cycles and are important tools in bioengineering for natural products and nanotechnology. Diatoms and other algae growing at varying resource-limited growth rates allocate carbon to different metabolic pathways to optimize growth; however, the molecular mechanisms controlling these pathway gating strategies are not...

  • The fractal structure of surface water waves near breaking

    Creator:
    Munzenmayer, Katja
    Abstract:
    The goal of this research project is to determine the fractal nature, if any, which certain surface water waves exhibit when viewed on a microscopic scale. We make use of the mathematical formulation of non-viscous fluids describing their physical properties. Using these expressions and including boundary conditions for free surfaces...

  • Parenting style and practice : predictors of behavioral regulation in preschool

    Creator:
    Pritchard, Megan E.
    Abstract:
    Increasing numbers of children are entering kindergarten without the behavioral skills needed to cope with the demands of the classroom environment. Moreover, a number of studies have documented that young children's behavioral regulation (including attention, working memory, and inhibitory control skills) plays an important role in later academic achievement (McClelland,...

  • Intestinal Lesions and Parasites Associated with Senescence and Prespawn Mortality in Chinook Salmon (Oncorhynchus tshawytscha)

    Creator:
    Nervino, Stephanie A.
    Abstract:
    Pre-spawning mortality (PSM) presents a major problem for population recovery of spring Chinook salmon (Oncorhynchus tshawytscha) in the Willamette River basin. In certain reaches and years, PSM has exceeded 90%. Histology has been used as the primary diagnostic method to investigate PSM in the Chinook Salmon, and a collection of...
