  • 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...

  • Failure analysis of Muller-C-element

    Creator:
    Chew, Oonpin
    Abstract:
    Asynchronous circuits have recently been a breakthrough in many high performance computers. The concept of asynchronous circuits which started a long time ago has slowly grasped the attention of many designers. The Muller-C-element is an important control block in many asynchronous designs and therefore it is important to understand some...

  • LORAN-C receiver position estimation from noisy time-difference data

    Creator:
    Weisshaar, Andreas
    Abstract:
    In order to analyze the accuracy of the navigation system LORAN-C, we have collected time - difference (TD) data from the U.S. west coast chain (9940) at a fixed receiver location (Corvallis, Oregon). The analysis of the TD data shows an unexpected high correlation between the TDs as well as...

  • 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...

  • Hybrid computer simulation of wind-driven ocean currents

    Creator:
    Vithayathil, Francis Joseph
    Abstract:
    A simulation method using a hybrid computer is developed in this dissertation to enhance the study of wind-driven ocean circulation. The simulation is based on the mathematical model developed by Ekman. Pure digital simulation is not economical due to excessive computer time required for the solution of the partial differential...

  • A model of the likelihood of stimulation or tolerance of the B lymphocyte

    Creator:
    Peterson, Patricia A.
    Abstract:
    The B lymphocyte is the immune cell responsible for the production of antibodies. It has receptor molecules on its surface which bind to a molecule known as an antigen. The antigen either stimulates the cell to produce antibodies or tolerizes it so that it is unable to produce antibodies. It...

  • 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 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...

  • 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...

  • 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....
