  • Cellular synthesis of synchronous sequential machines

    Creator:
    Hu, Sung Chiao
    Abstract:
    With the advancing solid-state technology, it is necessary to develop new techniques for synthesizing digital networks. The regular pattern of cellular circuits seems to be the best fitted for the new LSI technology. Recently, cellular implementations of comibinational circuits have received considerable attention but very little attention has been given...

  • Evaluation of grapevine red blotch virus epidemiology with reference to potential insect vectors

    Creator:
    Dalton, Daniel T.
    Abstract:
    Grapevine red blotch virus (GRBV), the causal agent of red blotch disease (RBD) in grapevine, Vitis vinifera L., is an emerging pathogen of significance to the wine grape industry of Oregon, USA. To address knowledge gaps of GRBV epidemiology, spread of GRBV was evaluated in Oregon vineyards over four years....

  • 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...

  • Adaptive, wideband analog-to-digital conversion for convergent communication systems

    Creator:
    Batten, Robert D., 1973-
    Abstract:
    The exponential rate of advances in modern communication devices in the last several years have brought us higher levels of functionality and performance as well as reductions in physical size and power consumption. To continue this rate of advancement, next generation systems require wider bandwidth and higher resolution ADCs. Additionally,...

  • Automated verilog-to-layout synthesis of ADCs using custom analog cells

    Creator:
    Waters, Allen
    Abstract:
    A procedure for automating the design and layout of analog-to-digital converters (ADCs) is presented. This procedure makes use of the existing synthesis and place-and-route tools that are common in digital circuit design. A method for adding rudimentary analog cells to the standard library is described, allowing the designer to synthesize...

  • Supporting Learning and Thinking with Multiple Representations in Upper Division Physics Courses

    Creator:
    Alfson, Jonathan W.
    Abstract:
    Physicists solve problems and communicate their work using many external representations, such as equations, words, diagrams, graphs, sketches, pictures, and more. To learn physics, then, students must learn to use external representations. In this dissertation, I present three manuscripts. Each manuscript discusses how upper-division Paradigms in Physics students use multiple...

  • Testing of wave energy converters using the Ocean Sentinel Instrumentation Buoy

    Creator:
    Lettenmaier, Terrance
    Abstract:
    Ocean testing of Wave Energy Converter (WEC) prototypes is necessary to facilitate commercial WEC development. The Ocean Sentinel Instrumentation Buoy, completed in August 2012, provides a stand-alone load for WEC prototypes during ocean testing. The first part of this work was to develop the power conversion and data acquisition equipment...

  • New Techniques to Monitor and Characterize Landslide Behavior and Controls Using Digital Terrain Models

    Creator:
    Senogles, Andrew
    Abstract:
    Coastal landslides and erosion are major natural hazards resulting in unstable slopes, constituting immense challenges to modern infrastructure. Developing, maintaining, and performing risk assessments of infrastructure on, or close to, these hazards require a detailed understanding of the geophysical processes destabilizing the slope. These efforts start with the collection of...

  • An assessment of southern Oregon clearcut and shelterwood cut cover types using LANDSAT MSS digital and supporting aircraft data

    Creator:
    Hawley, David Llewellyn
    Abstract:
    The feasibility of utilizing LANDSAT MSS data in assessing surface cover types and areal extent of clearcut and shelterwood cut harvest sites in southern Oregon was investigated. The research utilized extensive 'ground truth' information to evaluate the LANDSAT data. A three faceted ground truth collection scheme analyzed 1) U.S. Forest...

  • Low-power high-resolution delta-sigma ADC design techniques

    Creator:
    Wang, Tao
    Abstract:
    This dissertation presents a low-power high-resolution delta-sigma ADC. Two new architectural design techniques are proposed to reduce the power dissipation of the ADC. Compared to the conventional active adder, the direct charge transfer (DCT) adder greatly saves power by keeping the feedback factor of the active adder unity. However, the...
