1. Gostev I.M. “On the Identification of Open Curves” Abstract Problems of identification of plane unclosed curves are considered. Methods are proposed that allow one to classify graphic objects invariant to affine transformations. Details… 2. Zlokazov V.B., Bobrikov I.A., Balagurov A.M. “Mathematical Method for the Analysis of Polycrystal Phase Evolution” Abstract In experiments carried out in real-time or in-situ a multi-phase polycrystalline sample is step-wise exposed to external impacts (the heat, mechanical, etc. ones). Details… 3. Dikusar N.D. “Calculation of informative features based on piecewise polynomial smoothing contour lines” Abstract Coordinates measured on the contour line (CL) are smoothed by the rms-algorithm of piecewise polynomial approximation (RMSPPA) of the 12-th order.
