  • Characterization of the near-field flow structure of an acoustically self-excited jet in a large enclosure using particle image velocimetry (PIV)

    Creator:
    Tobias, Jason A.
    Abstract:
    An experimental study of the near-field flow structure produced by an incompressible turbulent Acoustically Self-Excited Jet (ASEJ) in a large enclosure using Particle Image Velocimetry (PIV) is presented. The salient feature of this jet is that it provides an increase in near-field mixing and turbulence without additional external power input....

  • Wood properties and use of sensor technology to improve optimal bucking and value recovery of Douglas-fir

    Creator:
    Acuna, Mauricio A.
    Abstract:
    There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...

  • Network coding in relay networks

    Creator:
    Alban, Eduardo
    Abstract:
    Transmission over wireless networks presents multiple technical challenges due to noise, interference, fading, power constraints and bandwidth limitation. Different solutions have been propposed to overcome these issues and some of them are treated here. Cooperative diversity has been proposed as an implementation for networks where terminals are restricted to using...

  • Nongenomic action of progesterone inhibits oxytocin signaling through the ovine oxytocin receptor

    Creator:
    Bishop, Cecily V.
    Abstract:
    Experiments were conducted to characterize the nongenomic effects of progesterone (P4) on binding of oxytocin (OT) to the ovine oxytocin receptor (OTR) and signal transduction. The dose-response relationship of P4 to OT binding to the OTR in endometrium was examined. Progesterone interfered with the binding of OT to the OTR...

  • An emerging role for the exocyst : plant morphogenesis

    Creator:
    Cole, Rex A.
    Abstract:
    Plants develop a vast array of cell shapes and sizes by selectively modifying their surrounding cell walls to expand in some regions and not in others. This process of morphogenesis requires the delivery of secretory vesicles to specific locations at the cell periphery, where exocytosis adds new membrane and proteins...

  • An experimental study of ammonia-water bubble absorption in a constrained microscale film

    Creator:
    Jenks, Jeromy W.
    Abstract:
    An experimental study of absorption of ammonia into a constrained thin film of ammonia-water solution is presented. A large aspect ratio microchannel with one of its walls formed by a porous material is used to constrain the thickness of the liquid film. Experiments were performed at a pressure of 1,...

  • Investigation and comparison of generators for dynamic operation in ocean buoys

    Creator:
    Schacher, Anthony Clinton
    Abstract:
    A significantly untapped renewable energy source exists in the world's oceans. It is estimated that if 0.2% of the ocean's untapped energy could be harnessed, it could provide power sufficient for the entire world. Ocean energy extraction is an old concept, and it is currently seeing the benefit of advancing...

  • Patoka : four stories of Southern Indiana

    Creator:
    Drew, Christopher M. (Christopher Max)
    Abstract:
    These stories are an attempt to give a distinct literary voice to the people and places of rural Southern Indiana. They also strive to deal with certain elements indigenous to that region, some of which can be described generally as the tension between modernization and tradition, family and marriage as...

  • Subwavelength light confinement and quantum chaos in micro- and nano-structured metamaterials

    Creator:
    Govyadinov, Alexander A.
    Abstract:
    This dissertation concerns a broad range of unique phenomena related to the light propagation at nano- and micro-scales. To access the nano-domain, we introduce anisotropy-based waveguides with positive- and negative-index modes. These novel structures allow energy propagation in subwavelength regions and, in contrast to surface waves, have the mode structure...

  • Spatial interpolation in other dimensions

    Creator:
    Martin, Peter
    Abstract:
    The purpose of this work is to broaden the theoretical foundations of interpolation of spatial data, by showing how ideas and methods from information theory and signal processing are applicable to the the work of geographers. Attention is drawn to the distinction between what we study and how we represent...
