  • An historical review of Kolb's formulation of experiential learning theory

    Creator:
    Hickcox, Leslie K. (Leslie Kay), 1951-
    Abstract:
    The central purposes of this study were to review the historical sources of David Kolb's formulation of experiential learning theory, and to determine the effect and application of Kolb's theory and Learning Style Inventory as reflected in the literature between 1971 and 1990. It was found that Kolb based his...

  • Insights into Centennial-Scale Salt Marsh Morphodynamics from the Oregon Coast

    Creator:
    Peck, Erin K.
    Abstract:
    Quantification and comparison of morphological changes over the last ~300 y in Oregon salt marshes provide valuable insights into the tectonic, hydroclimatic, and anthropogenic processes shaping this important intertidal zone. Understanding of the rates and drivers of salt marsh change contextualizes intertidal habitats within the sediment routing system (i.e., source...

  • Spatial and temporal characteristics of bottom-trawl fish assemblages of the continental shelf and upper slope of the Pacific Coast of the United States, 1977-1992

    Creator:
    Jay, Chadwick V.
    Abstract:
    Twenty-three bottom-trawl fish assemblages were identified from the relative biomass of 33 dominant species that occurred in the National Marine Fisheries Services' triennial trawl surveys over the continental shelf and upper slope off California, Oregon, and Washington from 1977 to 1992. The assemblages accounted for about 70% of the total...

  • Evaluating Biochar for the Sustainable Treatment of Heavy Metals in Stormwater: Characteristics, Mechanisms, and Barriers

    Creator:
    Burch, Sarah
    Abstract:
    Heavy metals, such as copper, zinc, and cadmium, are ubiquitous in stormwater and potentially toxic to aquatic organisms at low concentrations. Removal of heavy metals contamination by conventional treatment is expensive and does not always reduce metals concentrations low enough to ensure safety of all aquatic species. This research seeks...

  • The Variable Speed Wave Equation and Perfectly Matched Layers

    Creator:
    Kim, Dojin
    Abstract:
    A perfectly matched layer (PML) is widely used to model many different types of wave propagation in different media. It has been found that a PML is often very effective and also easy to set, but still many questions remain. We introduce a new formulation from regularizing the classical Un-Split...

  • Unique determination of acoustic properties from thermoacoustic data

    Creator:
    Hickmann, Kyle Scott
    Abstract:
    The extent to which thermoacoustic data determines the acoustic properties of an object was studied. In the case of one dimensional thermoacoustic imaging it was shown that constant acoustic profiles are uniquely specified from measurements. For a radial thermoacoustic problem we have shown that if the acoustic source is radial...

  • 3D cone beam reconstruction formulas for the transverse-ray transform with source points on a curve

    Creator:
    Wongsason, Patcharee
    Abstract:
    3D vector tomography has been explored and results have been achieved in the last few decades. Among these was a reconstruction formula for the solenoidal part of a vector field from its Doppler transform with sources on a curve. The Doppler transform of a vector field is the line integral...

  • The unitary model operator approach to structure in the 2s-1d shell

    Creator:
    Nisley, Richard Arthur
    Abstract:
    Effective two-body interactions were obtained from realistic nucleon-nucleon potentials and applications made in calculations of ground state properties of even-even N=Z light nuclei. The admixture of high momentum states into the nuclear wavefunction caused by the strong, short-range repulsion of the two-nucleon force was taken into account by making a...

  • Performance-based seismic design of light-frame shearwalls

    Creator:
    Kim, Jun Hee
    Abstract:
    Performance-based design has gained interest in recent years among structural designers and researchers. Performance-based design includes selection of appropriate building sites, structural systems and configurations, as well as analytical procedures used in the design process, to confirm that the structure has adequate strength, stiffness and energy dissipation capacity to respond...

  • Load sharing and system factors for light-frame wall systems

    Creator:
    Yu, Guangren
    Abstract:
    A considerable amount of research has focused on load-sharing and system effects in repetitive-member wood floor systems subject to transverse loading. However, relatively few studies have been conducted to investigate load-sharing and system effects in repetitive-member wall systems which may be subject to combined transverse and gravity (vertical) loading, and...
