  • Growth and characterization of zinc ferrite thin films for high frequency applications

    Creator:
    Hu, Jiqing
    Abstract:
    Ferrites have been used for various high frequency applications as bulk materials. These applications, however, are limited to large dimension devices. In this thesis, thin film ferrites were deposited from a low temperature solution-based deposition process that is suitable for micro-scale high frequency applications. The low temperature nature of this...

  • Enhanced-accuracy oversampled data converters

    Creator:
    Ceballos, Jose Luis
    Abstract:
    Digital-to-analog converters (DACs) suffer from static and dynamic nonlinearity problems, which degrade their accuracy and performance. Mismatch errors in the analog components restrict the maximum achievable linearity. This thesis presents various techniques for correcting these errors. It describes a correction process for the nonlinear behavior of DACs, on three different...

  • An efficient and accurate method of estimating substrate noise coupling in heavily doped substrates

    Creator:
    Arunachalam, Sasi Kumar S.
    Abstract:
    This thesis presents a Z-parameter based model to predict the substratenoise coupling between two contacts in a heavily doped substrate for frequenciesless than 2 GHz. The empirical model is scalable with contact size and spacingsbetween the contacts and model parameters can be readily extracted from simu-lated or measured data. The...

  • A domain-specific embedded language for probabilistic programming

    Creator:
    Kollmansberger, Steven
    Abstract:
    Functional programming is concerned with referential transparency, that is, given a certain function and its parameter, that the result will always be the same. However, it seems that this is violated in applications involving uncertainty, such as rolling a dice. This thesis defines the background of probabilistic programming and domain-specific...

  • Patterns of age and growth in young-of-year rockfish, sebastes spp., along the Oregon coast

    Creator:
    Young, Thomas
    Abstract:
    Rockfish of the genus Sebastes are important components of Oregon reef communities. I examined patterns of age and growth in young-of-year rockfish across two nested spatial scales – local and regional – along the Oregon coast. Using otolith microstructural examination, I examined the relative importance of local versus regional factors...

  • Expression and Function of Populus Homologs to TERMINAL FLOWER 1 Genes: Roles in Onset of Flowering and Shoot Phenology

    Creator:
    Mohamed, Rozi
    Abstract:
    We isolated and characterized the expression of two genes from Populus trichocarpa that are homologous to the TERMINAL FLOWER 1 (TFL1) gene from the model annual plant Arabidopsis. In Arabidopsis, overexpression of the TFL1 gene extends the vegetative growth phase, and the homozygous mutant tfl1 allele causes early flowering and...

  • Phytoplankton shading of marine benthic macrophytes: Implications for intertidal community structure

    Creator:
    Kavanaugh, Maria T.
    Abstract:
    Previous observations of light levels and phytoplankton abundances along the Oregon coast demonstrated that phytoplankton attenuated light sufficiently to potentially limit the growth of intertidal macrophytes and therefore structure local intertidal communities. Inspired by this observation, in spring 2004, I initiated a study to quantify the direct and indirect benthic...

  • Range-wide abundance and fluctuating asymmetry patterns of sagebrush-obligate passerine birds

    Creator:
    Krissman, Cortnie M.
    Abstract:
    North American sagebrush (Artemisia spp.) ecosystems are suffering from reductions in habitat extent and quality. Only about 50% of sagebrush remains from pre-settlement conditions, and much of the remaining habitat is fragmented or degraded by invasive species, fire suppression and overgrazing. Sagebrush-obligate species are experiencing population declines as a result...

  • Grazing, nutrients, and marine benthic algae : insights into the drivers and protection of diversity

    Creator:
    Guerry, Anne D., 1973-
    Abstract:
    Two of the most powerful ways in which humans have altered ecosystems are by increasing productivity and changing the densities of important consumers. The bottom-up effects of productivity and the top-down effects of consumers have been identified as primary determinants of biological diversity, though the links between them remain unclear....

  • Spatial and temporal variability of carbon dynamics in a tropical forest of Colombia

    Creator:
    Sierra, Carlos Alberto
    Abstract:
    Despite the importance of tropical forest ecosystems in the global carbon cycle, there have been few studies of carbon dynamics in this biome. The magnitude of carbon stocks in the tropics and their changes over time are poorly known since ground-based observations are lacking. In this study, total carbon stocks...
