  • Real-time data quality assessment using linear prediction

    Creator:
    Rentola, Christopher T. W.
    Abstract:
    The U.S. Air Force models many naturally occurring phenomena. To validate such models, an automated data collection system is used. Since validation is dependent upon correct data, an inexpensive method to detect erroneous data was investigated. The method uses a Wiener filter to predict values one sample in advance. If...

  • A new RISC architecture for high speed data acquisition

    Creator:
    Gribble, Donald L.
    Abstract:
    This thesis describes the design of a RISC architecture for high speed data acquisition. The structure of existing data acquisition systems is first examined. An instruction set is created to allow the data acquisition system to serve a wide variety of applications. The architecture is designed to allow the execution...

  • Mini-Data Acquisition System for Small-Scale Testing of Wave Energy Converters

    Creator:
    Dizon, Christian N.
    Abstract:
    Data acquisition (DAQ) systems are a necessary component for products whose outcomes depend on collected information throughout its operation. Current systems are directed towards users utilizing custom hardware, software, and requiring its user to have high-level skills in coding and system setup; but with the increasing interest in renewable energy,...

  • New Techniques for Multi-Channel Biosignal Acquisition and Low-Power, Low-Resistance-Measurement Systems

    Creator:
    Kim, Jinyong
    Abstract:
    Dense electrical recording of biosignals has been developed to provide spatial resolution and precise temporal information for health monitoring, diagnostics, and clinical research. However, more electrodes require more wires, and wiring density quickly becomes a limiting factor. To break this bottleneck, we proposed a frequency-division multiplexing (FDM) based architecture for...

  • Development of two-variable maximum power point tracking control for ocean wave energy converters utilizing a power analysis and data acquisition system

    Creator:
    Amon, Ean A.
    Abstract:
    Ocean wave energy shows great potential as a developing form of renewable energy. However, challenges arise in maturing this technology to achieve cost-effective energy conversion. Development and testing of wave energy converters can be problematic due to the harsh environment in which they are operated. To promote development of this...

  • A comparative study between sinusoidal and squarewave clocking for alleviating the jitter limitation in multi-gigaHertz ADCs

    Creator:
    Kesharwani, Divya
    Abstract:
    Various applications like wireless UWB communication, fast data acquisition systems and digital storage oscilloscopes needs ADCs with instantaneous input signal bandwidth from 0.1-40 GigaHertz range with 6-10 bits of resolution -- a challenging task and an impressive goal to achieve. Flash ADCs have been conventionally employed to achieve these goals...

  • 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...
