  • Analysis and design of bandpass delta-sigma A/D converters

    Creator:
    Zhai, Dalun
    Abstract:
    A new approach to oversampled delta-sigma A/D converters ( AZ modulators ) is introduced, where a differential pseudo-Npath filter stage is used as a basic cell. In this band-pass application, the z to -zN transformation is employed to realize a RAM-type pseudo-2-path lossless integrator. The bandpass second-order and 4th-order delta-sigma...

  • The role of competition, community, and priority in the discovery of the tau lepton

    Creator:
    Swanner, Leandra
    Abstract:
    This study examines the interactions between the scientific communities of the Lawrence Berkeley Laboratory (LBL) and the Stanford Linear Accelerator Center (SLAC) in the discovery of the tau lepton by physicist Martin Perl between 1973- 1977. Perl became interested in searching for heavy leptons through positron-electron collision experiments using the...

  • Oregon's coastal marine recreational fishing community : The state of communication with the fisheries management community

    Creator:
    Opsommer, Laura
    Abstract:
    The Pacific Northwest and Oregon in particular, have a rich fishing history. There are several fishing communities that rely on the resources found within Oregon waters. This research project explores communication in one particular fishing community, the coastal marine recreational fishing community (CMRFC) and the fisheries management community (FMC). Objectives...

  • The effect of nicotinic acid supplementation during late-gestation on lipolysis and feed intake during the transition period

    Creator:
    Chamberlain, Jason L.
    Abstract:
    An experiment was conducted with 27 multiparous Holstein and 27 multiparous Jersey cows to determine if nicotinic acid (NA) supplementation during the prepartum phase of the transition period decreases lipolysis and improves dry matter intake and to determine if Holstein and Jersey cows respond similarly to NA supplementation. Cows were...

  • Evolution of a pheromone signaling system in the salamander genus Plethodon (Amphibia: Plethodontidae)

    Creator:
    Picard, Amy L.
    Abstract:
    Animal signaling systems frequently utilize multiple traits to produce and transmit a signal. These system elements may span multiple levels of organization. Functional integration of these traits may be expected to generate concordance in evolutionary pattern among system elements, such that evolutionary change in one system component is correlated with...

  • Deformation imaging

    Creator:
    Margiocco, Marco L.
    Abstract:
    Recent developments in the field of clinical echocardiography allow the ultrasonographer to objectively quantify both regional and global myocardial function. Regional deformation (Strain) and deformation rate (Strain Rate) are novel indices of ventricular function that can be estimated non-invasively by ultrasonographic interrogation of the heart. Deformation Imaging (DI)represents a family...

  • Factors influencing nest success of greater sandhill cranes at Malheur National Wildlife Refuge, Oregon

    Creator:
    Ivey, Gary L.
    Abstract:
    I developed a priori hypotheses and used logistic regression to model Greater Sandhill Crane (Grus canadensis tabida) nest success in relation to weather, habitat and management variables for cranes breeding at Malheur National Wildlife Refuge (MNWR) in southeast Oregon. My primary interest was to investigate the effects of habitat conditions...

  • Northern goshawk breeding habitat selection within high-elevation forests of southwestern Colorado

    Creator:
    Ferland, Cheron L.
    Abstract:
    The northern goshawk (Accipiter gentilis) is a species of concern in the western United States due to its association with mature structural stage forests. I employed a use-versus-availability study design to quantify the vegetative, physiographic, and landscape variables associated with goshawk breeding habitat selection in the San Juan Mountains of...

  • 3-D finite element modeling in OpenSees for bridge live-load girder distribution factors

    Creator:
    Scoggins, Luke A.
    Abstract:
    A generalized, three-dimensional, finite element bridge model was created in order to efficiently and accurately assess live-load girder distribution factors for a variety of bridge types. This model shortens the time required by bridge analysts to develop individual finite element models for bridges of varying geometries. The creation of the...

  • Assessing the impact of temperature on grape phenolic metabolism

    Creator:
    Cohen, Seth D.
    Abstract:
    Many climatic factors influence grape berry composition including nutrient status, water availability, biotic stress, sun exposure and temperature. Previous research examined the effects of many factors listed above and much progress has been made. It is often difficult, however, to separate effects that typically confound each other, such as sun...
