  • Publication number: 20250077722
    Abstract: A calculation apparatus for calculating a statistics property of a structural model comprises a pre-calculation structural model acquiring section for acquiring a pre-calculation structural model in which atoms are periodically arranged, a pre-calculation information acquiring section for acquiring pre-calculation information that specifies atoms periodically arranged in the pre-calculation structural model, a post-calculation structural model acquiring section for acquiring a post-calculation structural model calculated by using the pre-calculation structural model as source data, a post-calculation information acquiring section for acquiring cluster information obtained by clustering atoms in the post-calculation structural model based on the pre-calculation information, and atom position information that is position information of atoms in the post-calculation structural model, and a statistics property calculating section for calculating centroid positions of atoms having the same cluster information base

  • Publication number: 20240120036
    Abstract: A processing apparatus for processing a structure factor including total scattering data and data of a structural model are provided comprises a structure factor acquiring section for acquiring a first structure factor based on measured total scattering data; a data converting section for separating the first structure factor into a short-range correlation and a long-range correlation; and a scattering intensity calculating section for acquiring a structural model indicating an atomic arrangement in a finite region, calculating a short-range scattering intensity of the structural model and calculating a second structure factor from the short-range scattering intensity and the long-range correlation.

  • Patent number: 11835131
    Abstract: A control apparatus for a vehicle provided with (i) a power source, (ii) drive wheels and (iii) a fluid transmission device disposed between the power source and the drive wheels and including a lockup clutch to which a fluid pressure is supplied. A feedback control is executed for correcting a command value of the fluid pressure by a correction amount such that an actual value of a slip amount of the lockup clutch becomes substantially equal to the target value of the slip amount in a slip control. When the actual value has been converged into a given range with respect to the target value, the correction amount is obtained, and the command value for a next execution of the slip control is corrected by learning with use of the obtained correction amount. The given range is set depending on the target value of the slip amount.
