The problem of the human body localization in the video stream using the growing neural gas and feature description based on the Histograms of Oriented Gradients is solved. The original neuro-fuzzy model of growing neural gas for reinforcement learning (GNG-FIS) is used as a basis of the algorithm. The modification of GNG-FIS algorithm using two-pass training with fuzzy remarking of classes and building of a heat map is also proposed. As follows from the experiments, the index of the correct localizations of the developed classifier was 93%, that allows the use of the algorithm in real systems of situational video analytics. © 2017 The Authors.

The intelligent system is constructed by using three basic principles of decomposition, the neural network and fuzzy approach, swarm intelligence, expert systems, pattern recognition, video content analysis, simultaneous localization and mapping, fractal and the wavelet-Analysis. The principle of design, the structural and functional schemes of the security intelligent system are offered. These principle and schemes have some advantages over the traditional ones due to the fusion of the latest technologies. The synthesis method is based on the hierarchical principle of system design with the fusion of cybernetic approach, technologies of the artificial intelligence, the navigation and methods of digital signal processing. © 2017 IEEE.

This paper is devoted to connections between trace monoids and cubical sets. We prove that the category of trace monoids is isomorphic to the category of generalized tori and it is a reflective subcategory of the category of cubical sets. Adjoint functors between the categories of cubical sets and trace monoid actions are constructed. These functors carry independence preserving morphisms in the independence preserving morphisms. This allows us to build adjoint functors between the category of weak asynchronous systems and the category of higher dimensional automata. © 2013 Ahmet A. Husainov.

The problem decision for random vectors estimation by using regression analysis with unknown type of the regression function and wavelets is given. The regression and wavelet based estimation algorithm is described. The regression and wavelet based estimation algorithm gives the common decision of the problem for nonlinear, non-Gaussian case. The example for scalar linear problem is considered. It is shown that the Bayesian and the alternative regression and wavelet based algorithms provide estimates with the close accuracy.

Problems of inelastic straining of three-dimensional bodies with large displacements and rotations are considered. In addition to the sought fields, surface forces and boundary displacements, original size and shape have also to be determined from specified residual displacements in these problems. Currently, forming of light metals poses tremendous challenges due to their low ductility at room temperature and their unusual deformation characteristics at hotcold work: strong asymmetry between tensile and compressive behavior, and a very pronounced anisotropy. We proposed the constitutive models of steady-state creep of initially transverse isotropy structural materials the kind of the stress state has influence [1]. The forming process considered includes two stages: active stage of elastoviscoplastic straining of the blank in the die tooling and passive stage of unloading of the blank withdrawn from the die tooling. The final stressstrain state at the active stage is the initial state for the passive stage. Unloading is considered as purely elastic straining, with no increments of inelastic strains. The active stage, in turn, also includes two steps. At the first step, the frontal faces of the "cold" blank are pressed to the working surfaces of the die tooling, which results in elastoplastic straining of the blank. The second step includes the processes of stress relaxation and creep strain in the blank fixed in this die tooling during a given time at an elevated ageing temperature. Computer modeling of these forming processes involves the use of the finite element method for consecutive solutions of threedimensional quasi-static problems of elastoplastic straining, relaxation, and unloading, and also determining boundary conditions from given residual displacements [2] . The paper gives basics of the developed computer-aided system of design, modeling, and electronic simulation targeting the processes of manufacture of wing integral panels. System application data resulting from computation of 3D-involute of a CAD-based panel model, determination of working surfaces of die tooling, three-dimensional analysis of stresses, and simulation of panel shaping under diverse thermo-mechanical and speed conditions are demonstrated. Modeling of forming of wing panels of the SSJ-100 aircraft are considered [2,3]. The modeling results can be used to calculate the die tooling, determine the panel processibility, and control panel rejection in the course of forming [3].

We review herein the synthesis and investigation of iron(II) coordination compounds with 1,2,4-triazoles or tris(pyrazol-1-yl)methanes as ligands. Both groups of complexes demonstrate thermally induced spin crossover accompanied by thermochromism [pink (magenta) ↔white color change]. Factors that influence the nature and temperature of the spin crossover are discussed. © 2013 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

Authors of the present paper examined near hundred of Computer-Aided Software Engineering (CASE) systems. It is offered to consider CASE-systems evolution in the form of TRIZ-fractal matrix. Herewith the motivating force of evolution is resolution of contradictions which have appeared at the previous stages except that contradictions are resolved using TRIZ tools. Criteria which are connected with TRIZ concept "ideality" and according to which CASE-systems develop are practicality and investment. In the paper it is singled out CASE-systems development lines, their advantages and disadvantages and is analyzed purpose and development trend of each line. Usage of the present approach for training allows to reduce significantly time for learning different CASE-systems by means of knowledge systematization. On the other side this systematization will allow first to find out the priority of following development of CASE-systems, second to simplify significantly a choice of CASE-systems being used at enterprises and third to approve TRIZ tools application for contradictions resolution in CASE-systems. © 2011 Published by Elsevier Ltd.

The author proposes an axiomatic model of porous medium compaction under triaxial compression. The model results agree well with the in situ measurements in carbonates down to 500 m depth and in snow banks to 10 m thick. The constitutive relations of the model are simple and pass into the volume Hooke law and into the perfect gas state equation in the respective limiting cases. © 2011 Pleiades Publishing, Ltd.

The aim of this paper is to study the homology theory of partial monoid actions and apply it to computing the homology groups of mathematical models for concurrency. We study the Baues-Wirsching homology groups of a small category associated with a partial monoid action on a set. We prove that these groups can be reduced to the Leech homology groups of the monoid. For a trace monoid with a partial action on a set, we build a complex of free Abelian groups for computing the homology groups of this small category. It allows us to solve the problem posed by the author on the construction of an algorithm to computing the homology groups of elementary Petri nets. We describe the algorithm and give examples of computing the homology groups. © 2012 Springer Science+Business Media B.V.
