This paper presents an algorithm for segmentation of convex cells with partially undefined edges based on application of a
marker-controlled watershed transform to a combination of a source grayscale image and the result of a “geodesic distance”
morphological operation, applied to the result of binarization of a source image. The presented approach is used in computer
image processing systems for analysis of several industrial materials.

PART I Mathematico-Philosophical Prolegomena Part II of this essay was written before Part I and offered to the Third Annual Symposium of the American Society for Cybernetics as a topic of discussion. However, owing to unforeseen circumstances, the paper was not presented at the Symposium. This turned out to be a blessing in disguise. In order to conform to the time limit for oral presentation Part II was written in a highly condensed manner and there was no opportunity to elaborate on the general epistemological aspect which served as the starting point for the intended confrontation between natural numbers and structural systems of higher complexity than our traditional logic offers. We are determined to make up for this omission in Part I because we believe that the theoretical goal of Part II will be better understood if the present author clarifies his attitude toward the basic concept of organism and its mathematical treatment in cybernetic research. 相似文献

The geoinformation system for handheld computers (PDAs) makes it possible to solve a wide range of geographically dispersed
data (GDD) processing problems. The developed program software (PS) based on effective models and GDD processing methods has
allowed significantly increasing the GDD processing rate in PDAs.

The paper is devoted to the 75th anniversary of the Kyiv mathematician Naum Shor and is focused on his three central ideas:
generalized gradient descent (1962), the use of linear nonorthogonal space transformations to improve the conditionality of
ravine functions (1969), and dual approach for finding bounds of the objective function in nonconvex quadratic models (1985).
Examples of the application of these ideas in methods and algorithms developed at the V. M. Glushkov Institute of Cybernetics
of the NAS of Ukraine are given. 相似文献

This article presents the results of ab initio quantum simulation of graphite-like structure formation from amorphous carbon. It is devoted to explaining a resistivity switching mechanism in experiments on phase-change memory. In this work, a two-scale molecular dynamics model is used, which consists of Car-Parrinello quantum molecular dynamics (CPMD) and modified Ehrenfest molecular dynamics. The results of simulation point out to the appearance of a layered graphite-like molecular structure at an increase in temperature. These changes in the atomic configuration can be considered as a second-order phase transition in nanostructured material, which leads to threshold resistivity switching. For calculations, the IBM BlueGene/P supercomputer installed at the Faculty of Computational Mathematics and Cybernetics of Moscow State University was used. 相似文献

A new method of image restoration based on the quasi-solution method for a compact set of functions with bounded total variation
is introduced. Application of this method does not require estimation of the noise level, which is necessary to choose the
regularization parameter in the Tikhonov regularization method. The approbation of this method with test images shows its
effectiveness for image deringing.
