    Details
    ISSN: 1573-2754
    Keywords: pansystems methodology ; artificial neural network (ANN) ; systems theory ; TP18 ; N94
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Mathematics , Physics
    Notes: Abstract In this paper, several definitions of composing panweighted networks and panweighted fields are given, a group of theorems about the logic conservation of compositions between panweighted networks and panweighted fields are proved. By combining the average field model, the future application of panweighted networks and panweighted fields in ANN is discussed.

    A Model for the Crystal Growth of YBa2Cu3O y (1998)
    Springer
    Journal of superconductivity 11 (1998), S. 347-352 
    Details
    ISSN: 1572-9605
    Keywords: Crystal growth ; morphology ; YBCO ; terraced crystals ; step growth
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract The crystal growth and crystal morphology are very important properties of YBa2Cu3O y superconductors. In this work, we approach these problems with polycrystals. Several typical crystal morphologies were observed by scanning electron microscopy, and the terraced crystals with a layer-by-layer structure were found to be the major form for the well-grown YBa2Cu3O y . To interpret the results, a step-growth model was proposed. In this model, each crystal terrace is close-packed with crystal particles in order. And the particles, each consisting of tens of crystal cells, are movable during crystal growth. Particles at edges or margins of small crystals can move to their larger neighboring crystals through diffusion. With this particle diffusion, small crystals vanish and large crystals grow larger. This proposed model is confirmed by experimental observations.

    Development of Twins in YBa2Cu3Oy Superconductor (1999)
    Springer
    Journal of superconductivity 12 (1999), S. 421-426 
    Details
    ISSN: 1572-9605
    Keywords: Crystal growth ; YBCO superconductor ; tetragonal ; orthorhombic ; twins
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract It is significant to study the problems how the tetragonal and orthorhombic structures of YBa2Cu3O y generate, since the structures closely relate to superconductivity. To deal with these problems, we approach the generation of tetragonal and orthorhombicity and their morphologies by SEM, TEM, and X-ray diffraction analysis, respectively. For interpreting the experimental phenomena, we put forward a crystal growth modal: the tetragonal grows at sintering temperatures, and the tetragonal transits to orthorhombicity and forms twins along [110] faces at annealing temperatures. This model agrees with experimental results well.

    Pansystems logic conservation of bifurcation, catastrophe, chaos and stability (1993)
    Springer
    Applied mathematics and mechanics 14 (1993), S. 367-370 
    Details
    ISSN: 1573-2754
    Keywords: pansystems methodology ; bifurcation ; catastrophe ; chaos and stability ; nonlinear mechanics ; pansystems logic conservation law
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Mathematics , Physics
    Notes: Abstract It is in references [4, 5] that the combination of the relative researches of pansystems methodology and the researches of bifurcation, catastrophe, chaos and stability in nonlinear mechanics was put forward and the concepts were redefined from the point of view of pansystems methodology. The present paper studies the logic conservation law of these nonlinear mechanics phenomena under the framework of pansystems methodology.
