  • Ternary arithmetic in direct digital control systems

    Creator:
    Seamans, David Alvin
    Abstract:
    The development of new electronic devices and design procedures applicable to ternary switching circuits suggests that it might be desirable to use ternary arithmetic in direct digital control systems. The advantages of decimal, binary, and ternary arithmetic in digital computers are discussed and a set of rules for signed -digit...

  • High speed adaptive logic circuit for adaptive signal processing

    Creator:
    Moriyasu, Hiro
    Abstract:
    A high speed adaptive signal processing concept and several high speed adaptive logic circuit elements are presented. The adaptive signal processing system operates in a "goal" oriented mode; the system tries to optimize its characteristics to achieve a given goal in spite of unforeseen variations in the inputs, the system,...

  • Computer and heating and air conditioning

    Creator:
    Hafez, Ghassan M. Ihsan
    Abstract:
    The repetitious nature of air conditioning calculation leads to arithmetic errors and a high cost of designing air conditioning systems. Short cut calculations are employed to limit the calculation and the chance of making errors. Computers with their high speed of calculation and the ability to make limited "logic's decisions...
