  • Reliability and Availability Analysis of Fusion Power Plants 

    Husseiny, A.؛ Kenarangui, R. (Materials and Energy Research Center, 1988-02-01)
    Major efforts are underway to develop fusion energy for use in electric power production in the furture. While fusion reactor concepts are being developed, appropriate attention must be given to problems relvant to the ...

  • Sulfur Species in Particulates Emitted from Reducing Coal Combustion and Pyrometallurgical Furnaces 

    Sadrnezhaad, S.K. (Materials and Energy Research Center, 1988-02-01)
    The method of X-Ray Photo-electron Spectroscopy is used to determine the chemical state of the sulfur species present in fly-ash samples produced by burning a number of pulverized coal samples under reducing conditions in ...

  • Design of Logic Network for Generating Sequency Ordered Hadamard Matrix H 

    Eghbal Jahromi, H.J. (Materials and Energy Research Center, 1988-02-01)
    A logic network to produce the sequency ordered Hadamard matrix H based on the property of gray code and orthogonal group codes is developed. The network uses a counter to generate Rademacher function such that the output ...

  • Digital Distance Relaying 

    Ranjbar, A. M. (Materials and Energy Research Center, 1988-02-01)
    Increasing interest is being shown in the use of microprocessor for protection, switching and data acquisition required in modern high voltage substations. One of the most difficult functions to fulfill is that of transmission ...

  • The Kinetics of Methanation on Nickel Catalysts 

    Cehn, Y. W. (Materials and Energy Research Center, 1988-02-01)
    An empirical rate equation was obtained for the methanation kinetics catalyzed by MCR-2X, a commercial catalyst prepared by Haldor-Topsoe. The studies were carried out in a fixed-bed reactor under differential conditions, ...

  • Stiffness Matrices for Axial and Bending Deformations of Non-Prismatic Beams with Linearly Varying Thickness 

    Sabir, A. B. (Materials and Energy Research Center, 1988-02-01)
    Siffness matrices for axial and bending deformations of a beam having a rectangular cross sectional area of constant width and linearly varying thickness are developed. A consistant load vector for a uniformly distributed ...

  • The Potentiodynamic Behavior of Copper in NaCI Solutions Studied by Auger and Photoelectron Spectroscopy 

    Avanessian, J. (Materials and Energy Research Center, 1988-02-01)
    The potentiodynamic behaviour of copper in brine solutions was studies. Auger and photo-electron spectroscopy were used together with electrochemical methods. It is demostrated that the passivation observed in potentiodynamic ...

  • Harmonic Response of Pile Groups to Dynamic Loading 

    Meek, J. L. (Materials and Energy Research Center, 1988-02-01)
    A completely general method of analysis for three-dimensional raked piles under harmonic excitation is discussed. The piles have been represented by a three-dimensional frame structure and the soil has been represented by ...
