  • Weather influence on Loran-C

    Creator:
    Graulich, Markus Günter
    Abstract:
    The influence of weather on the long range radio navigation system Loran-C was investigated. The variables analyzed over a period of 255 days were: time differences (TDs), TD signal-to-noise ratios, TD standard deviations (measured at a fixed receiver location in Corvallis, Oregon), time interval numbers (TINOs) (measured at the transmitter...

  • Analog integrated circuit design using GaAs C-HFETs

    Creator:
    Gupta, Rakhee
    Abstract:
    Present day data processing technology requires very high speed signal processing and data conversion rates. One such application which requires high speed is switched capacitor circuits used in Sigma-Delta modulators. A major active component of switched capacitor circuits is the monolithic operational amplifier(opamp). Because of the relatively poor speed performance...

  • Liquid crystal thermography : a new system for breast cancer detection

    Creator:
    Bichara, Kamal Fouad
    Abstract:
    A liquid crystal thermographic technique was developed for application to several problems in clinical medicine and physiology. The procedure was inexpensive, rapid, simple, versatile and acceptable to patients. Investigators in the past have used cholesteric liquid crystals for thermography but their use was limited to research in the medical field...

  • 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...

  • A parametric analysis of the capabilities of undersea acoustic imaging

    Creator:
    Calligan, C. C.
    Abstract:
    The feasibility of utilizing acoustic imaging techniques for improving the undersea viewing capability of small submersibles is investigated. The limiting values of major parameters in acoustic imaging systems are established and graphs which illustrate the parametric relationships are presented. A series of sample calculations illustrate how the graphs can be...

  • Compartmental analysis of the immune system

    Creator:
    Lawrence, Karen
    Abstract:
    A compartmental model of the immune system is simulated. Chapter I discusses the importance of such a model, reviews past immune system models, and summaries the immunological theory the model is based upon. In Chapter II, the compartmental representation of the immune system is developed from immunological and physiological theory....

  • Low-power high-linearity digital-to-analog converters

    Creator:
    Kuo, Ming-Hung
    Abstract:
    In this thesis work, a design of 14-bit, 20MS/s segmented digital-to-analog converter (DAC) is presented. The segmented DAC uses switched-capacitor configuration to implement 8 (LSB) + 6 (MSB) segmented architecture to achieve high performance for minimum area. The implemented LSB DAC is based on quasi-passive pipelined DAC that has been...

  • Model flexible assembly system

    Creator:
    Ho, Chi-Sung
    Abstract:
    Increasing automation and highly flexible manufacturing processes cause increasing complexity for manufacturing system. FMS (Flexible Manufacturing System) is an approach to solve this problem. Since the elements of the FMS and manufacturing process performance are closely interrelated, the application of simple modeling and emulation techniques in the planning stages for...

  • A graphical ethernet monitoring system (GEMS)

    Creator:
    Park, Chung Min
    Abstract:
    GEMS (Graphical Ethernet Monitoring System) is an enhancement to the SU-PC/IP NETWATCH program, for the graphical display and recording of computer network packets. SU-PC/IP (Stanford University Personal Computer/Internet Protocol) NETWATCH displays one line of information per packet, including the packet type, IP addresses, packet size, and protocol type, etc. This...

  • A study of the effect of the rotor coil couplings of a synchronous machine on its predicted transient response

    Creator:
    Nehrir, Mohammad Hashem
    Abstract:
    The effect of the mutual inductances between the rotor coils of a synchronous machine on its defined reactances and predicted transients are investigated. Two linearized models of the machine are considered. One uses the Laplace-Transform approach, with minimum number of assumptions on the inter-coil couplings, in developing a model for...
