  • A study of time series interpolation and decimation with signal processing applications

    Creator:
    Kraemer, Thomas Fredrick
    Abstract:
    Decimation and interpolation is shown to be an effective technique for reducing the storage requirements for bandlimited time series. Interpolation and decimation is theoretically developed using z-transform theory and graphically interperted. A sequence of data acquired by sampling a sonar signal is used to demonstrate the effects of decimation. Using...

  • Design and simulation of a DC-to-DC high-frequency series-resonant converter

    Creator:
    Yazdani-Buicki, Kiyandokht
    Abstract:
    A DC-to-DC power converter was designed on the basis of pulse-area modulation which is applied to a series-resonant circuit with internal frequency of 10 Khz The series-resonant circuit was placed directly in the energy path which provides a means for the thyristors to be naturally commutated. The design was tested...

  • Process segmentation and modelling applied to time series featuring the response of biological materials to toxic agents

    Creator:
    Teng, Angela
    Abstract:
    The detection of biological and chemical toxins has become one of the main concerns in environmental and military fields. In this framework, the department of Microbiology and Biochemistry at Oregon State University has discovered that fish living cells are promising indicators of the presence of a wide range of toxins....

  • Low-power high-performance 32-bit 0.5[u]m CMOS adder

    Creator:
    Shah, Parag Shantu
    Abstract:
    Currently, the two most critical factors of microprocessor design are performance and power. The optimum balance of these two factors is reflected in the speed-power product(SPP). 32-bit CMOS adders are used as representative circuits to investigate a method of reducing the SPP. The purpose of this thesis is to show...

  • Fabrication and characterization of modulation doped field effect transistors for quantum waveguide structures

    Creator:
    Yindeepol, Wipawan, 1960-
    Abstract:
    Split and normal gate A1GaAs /GaAs MODFETs were fabricated along with the ohmic test structures and the Hall bar geometries. The DC characteristics of normal gate transistors were evaluated at room temperature and at 77K and the threshold voltages were extracted from the measurements and compared to the theoretical results....

  • Digital stabilizer for brushless doubly-fed machine

    Creator:
    Krishnan, Sheela
    Abstract:
    The exceptional feature of the brushless doubly-fed machine is the lack of need for frequent replacement of brushes. The inherent instability of this machine has to be overcome for its application in adjustable speed drives and variable speed generation systems. Specific objectives were: to study the characteristics of the machine...

  • Evolving character controllers for collision preparation

    Creator:
    Rose, Robert W.
    Abstract:
    Full dynamic control of physically simulated characters is the holy grail of video games and other interactive applications. Recent advances in the field have presented controllers that can handle the balance and fall response after a collision. This thesis addresses the development of a controller that handles the response before...

  • Area efficiency improvement of CMOS charge pump circuits

    Creator:
    Perigny, Ryan
    Abstract:
    In this thesis, the literature relating to charge pump dc-dc converters and their uses is reviewed. Charge pumps are useful in many circuits, including low-voltage circuits, dynamic random access memory circuits, switched-capacitor circuits, EEPROM's and transceivers. The important issues relating to charge pump design are power efficiency, output voltage ripple...

    Abstract:
    Different gate length (0.5 μm 16 μm) Al GaAs/GaAs and AIGaAs /InGaAs High Electron Mobility Transistors were electrically characterized in order to compare the room temperature DC device performance with one-dimensional device models. Model parameters such as the channel mobility and source/drain series resistances are extracted from independent measurement of...

    Lim, Choo-chiang
    Abstract:
    The Control-Oriented Local Area Network (COLAN) is a distributed control system for a series of networked microcontrollers, which has been under development at Oregon State University since 1986. A reliable master controller, functioning both as a task scheduler and as a network controller, is required to allow users to perform...
