  • A computer controlled robot analyzer for in situ water quality monitoring

    Creator:
    Birch, Kenneth Norman
    Abstract:
    A new, computer oriented system for automatic, in situ monitoring of water quality is proposed which makes full and effective use of modern computer technology. The main objective of this thesis work was the development of the concept for in situ computer controlled experimenting as a reasonable and effective means...

  • A computer simulation model of land use dynamics in the State of Oregon

    Creator:
    Calligan, C. C.
    Abstract:
    The dynamics of land use in the State of Oregon are simulated on a digital computer. The introductory chapter outlines the complex nature of the problems facing the post-industrial society and argues that the scientific and professional estates share in the responsibility for public policy formulation. The second chapter .presents...

  • The use of electromagnetic Walsh waves in radar

    Creator:
    Schaffer, Alvin
    Abstract:
    The question of the suitability of Walsh functions or similar bi-valued functions used as a radar electromagnetic carrier waveform is considered. Walsh functions are described and effective sinusoidal steady state transfer functions are defined for transmission elements, antenna systems, and propagation media. The argument is made that the unit impulse...

  • A schemata model of real-time information processing systems

    Creator:
    Szulewski, Paul A.
    Abstract:
    In an attempt to provide a practical means to measure the information processing capacity of a real-time digital processing system a theoretical framework, the Real-Time Schemata, whose basis is a schematic description and a measure of "useful information," is presented. The description applies to processes that would typically be implemented...

  • Electrical and optical properties of semi-insulating and ion-implanted GaAs and InP

    Creator:
    Rhee, Jin Koo
    Abstract:
    The electrical and optical properties of semi-insulating, epitaxial and ion-implanted GaAs and InP have been characterized and analyzed. Electron and hole traps in semi-insulating GaAs and InP, with activation energies ΔE[subscript T] ranging from 0.16 ± 0.01 to 0.98 ± 0.01 eV, have been detected and characterized by Photo-Induced Current...

  • The analysis and design of a broadband microwave buffer amplifier

    Creator:
    Dunsmore, Joel P.
    Abstract:
    In microwave network analysis, proper matching of the measurement system is necessary to prevent measurement errors and provide a proper terminating impedance for the device-under-test. To obtain this matching, a buffer amplifier is often used in the first stage of the network analyzer. This study describes the design and analysis...

  • Fault diagnosis in a fully distributed local computer network

    Creator:
    Kwag, Hye Keun
    Abstract:
    Local computer networks are being installed in diverse application areas. Many of the networks employ a distributed control scheme, which has advantages in performance and reliability over a centralized one. However, distribution of control increases the difficulty in locating faulty hardware elements. Consequently, advantages may not be fully realized unless...

  • 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...

  • Voltage controller for a variable speed generation system

    Creator:
    Weigand, Claus H.
    Abstract:
    An important task of a Variable Speed Generation (VSG) system is the capability to maintain and control the terminal voltage at some desired value as determined by the reactive power dispatch strategy.The main objective is to design a sub-optimal fixed-parameter controller in the sense that constraints with respect to practical...
