     Computer Research and Modeling, 2014, v. 6, no. 3, pp. 357-364

     This paper describes a method of on-line signature identification using the short-time Fourier transform and wavelet transform with radial basis of a special kind. In carrying out the identification, we use dynamic properties signature. We adduce the assessment of the reliability of the proposed procedure.

     Keywords: on-line signature, short-time Fourier transform, wavelet transform, radial basis.

     Estimates of threshold and strength of percolation clusters on square lattices with (1,π)-neighborhood
     Computer Research and Modeling, 2014, v. 6, no. 3, pp. 405-414

     In this paper we consider statistical estimates of threshold and strength of percolation clusters on square lattices. The percolation threshold p_c and the strength of percolation clusters P_∞ for a square lattice with (1,π)-neighborhood depends not only on the lattice dimension, but also on the Minkowski exponent d. To estimate the strength of percolation clusters P_∞ proposed a new method of averaging the relative frequencies of the target subset of lattice sites. The implementation of this method is based on the SPSL package, released under GNU GPL-3 using the free programming language R.

     Keywords: site percolation, square lattice, non-metric Minkowski distance, Moore neighborhood, percolation threshold, strength of infinite clusters, R programming language, SPSL package.

     Mathematical modeling of the population dynamics of different age-group workers in the regional economy
     Computer Research and Modeling, 2014, v. 6, no. 3, pp. 441-454

     The article deals with the nonlinear model of population dynamics of different ages workers in the regional economy. The model is built on the principles underlying modeling in econophysics. The authors demonstrate the complex dynamics of the model regimes that impose fundamental limits on medium- and long-term forecast of employment in a region. By analogy with the biophysical approach the authors propose a classification of social interactions of the different age-group workers. The model analysis is given for the level of employment among age groups. The verification of the model performs on the statistical data of the Jewish Autonomous Region.

     Keywords: nonlinear dynamics, econophysics, biophysics, age group, employed population, employment, region.

     This work is devoted to development of an algorithm for numerical integration of differential equations potentially-streaming method simulation of non-equilibrium processes. This method was developed by the author in his earlier published works. In this paper, consideration is limited to systems with lumped parameters. Also previously developed method for analyzing the correctness of the author of the approximate solution of the system potentially-streaming equations for systems in lumped parameters. The purpose of this article is to combine this technique with modern numerical methods for integrating systems of ordinary differential equations and the development of methods of numerical integration of systems of equations potentially-streaming method that allows to guarantee the correctness of the approximate solution.

     Keywords: potentially-streaming method, equation potentially-streaming method, numerical integration of the equations, analysis of the correctness of approximate solutions.

     Computer Research and Modeling, 2014, v. 6, no. 4, pp. 495-502

     The kernel based object tracking algorithms were described that take in account the independent changes of the 4 and 5 out of 5 parameters of the elliptic tracking region. It is shown that in tracking this conditions are sufficient and attempts of prediction are not necessary.

     Grid-cloud services simulation for NICA project, as a mean of the efficiency increasing of their development
     Computer Research and Modeling, 2014, v. 6, no. 5, pp. 635-642

     A new grid and cloud services simulation for NICA accelerator complex data storage and processing system are described. This system is focused on improving the efficiency of the grid-cloud systems development by using work quality indicators of some real system to design and predict its evolution. For these purpose the simulation program are combined with real monitoring system of the grid-cloud service through a special database. An example of the program usage to simulate a sufficiently general cloud structure, which can be used for more common purposes, is given.

     Mathematical modeling of pulsating detonation wave using ENO-schemes of different approximation orders
     Computer Research and Modeling, 2014, v. 6, no. 5, pp. 643-653

     The results of the numerical investigations of pulsating detonation wave propagation using the ENO-schemes with the approximation orders from the first to the fourth inclusively are presented. The results obtained with the use of the schemes of different approximation orders demonstrate that the pattern of detonation wave propagation in acetylene-air mixture corresponds to the analytical estimates both qualitatively and quantitatively. For the hydrogen-air mixture none of the schemes concerned provides the stable detonation wave propagation. The transition from the regular mode to the marginal one with the subsequent detonation breakup is observed.

     Keywords: pulsating detonation wave, ENO-schemes, Runge–Kutta schemes.
