  • Phase Transformation Analysis in titanium at nanosecond time resolution
    Journal of Applied Physics, 2005
    Co-Authors: H Kleinschmidt, A Ziegler, Geoffrey H. Campbell, Jeffrey D. Colvin, O Bostanjoglo
    Abstract:

    Polycrystalline and mosaic bicrystalline titanium films were subjected to steep heating/cooling rate of 1011∕108Ks−1 by laser pulsing. The induced phase Transformations were followed by imaging and diffraction with a dynamic transmission electron microscope on the time scale of nanoseconds. On heating the film up to near the melting point with a 6-ns laser pulse, the low-temperature hcp phase transformed to the high-temperature bcc phase, with a nucleation rate of 1025m−3s−1 and a crystal-growth velocity of about 1000ms−1. Quenching of molten Ti first produced the bcc phase, which in turn transformed to the hcp phase within a few microseconds. Thus, hcp-bcc Transformations occur in Ti, even at the above high thermal rates. They are martensitic and not diffusion limited as claimed for Transformations at low thermal rates.

  • time dependent structural Transformation Analysis to high level petri net model with active state transition diagram
    BMC Systems Biology, 2010
    Co-Authors: Chen Li, Masao Nagasaki, Ayumu Saito, Satoru Miyano
    Abstract:

    Background With an accumulation of in silico data obtained by simulating large-scale biological networks, a new interest of research is emerging for elucidating how living organism functions over time in cells. Investigating the dynamic features of current computational models promises a deeper understanding of complex cellular processes. This leads us to develop a method that utilizes structural properties of the model over all simulation time steps. Further, user-friendly overviews of dynamic behaviors can be considered to provide a great help in understanding the variations of system mechanisms.

  • Toral automorphisms mapping and anti-toral Transformation Analysis
    Journal of Computer Applications, 2008
    Co-Authors: Huang Ting-zhu
    Abstract:

    Toral automorphisms mapping is a transform technology widely applied in digital image scramble.On certain condition the result can be reverted by controlling the Transformation time because of the periodicity of the toral automorphisms Transformation.In methods to this Transformation,its application and generalization are mostly confined to the scrambling of the period and the huge time cost of the reverting.Therefore,the anti-toral Transformation was studied.At first the Transformation was proved to be bijective,and then the common expression of the anti-toral Transformation was given.In the end,the experiment testifies that anti-Transformation reverting is better than the periodicity reverting.
