  • Convergence of the method of theoretical modeling X-ray absorption spectra for Ru XANES L 2,3-edges in the density functional theory (DFT) crystals as an example [Ru (NH3) 6 3 +

    The results of analysis of computational aspects of the method of obtaining the XANES spectra for Ru L2 ,3-edges by integrating the dipole transition matrix elements involving DFT. The convergence of the numerical integration procedure for the parameters used in the earlier papers, crystals as an example [Ru (NH3) 6] 3 +. More specifically, it is proved that it is possible to use a small area of ​​integration and big enough step between points, which helps to minimize the requirements for computing power and offers the prospect of using this method for the simulation of the XANES spectra in coordinated ruthenium catalysts for splitting water research in the field of solar energy.

  • Monitoring and modeling of group political perceptions of young people of Grozny (according to data early 2012)

    The paper presents the results of research level of perception a political order among students of Grozny (GGNI) at the beginning of 2012. The questioning method was used. In total 320 respondents were interviewed, and captured the age group from 17 years to 20 years. On national structure the group was almost uniform (95,9% - Chechens). The main purpose of questioning - the definition of the emotional component of the group political installation on the classical method of semantic differential Charles Osgood. A comparative analysis was carried out of the averaged semantic level of emotional portraits and making real political order. It is revealed, the image of an order is in the Republic 45% closer to positive "ideal" construct in comparison with image of an order in Russia as a whole. It is received, by the beginning of 2012 perception level considerably decreased to normal value (in comparison with "incredibly positive" 2011). Thus small excess of perception of a political order in the Republic remained.

    Keywords: a political order, a political tensions, semantic differential, factor analysis, the affective component, questioning

  • Two-dimensional trigonal chiral and hexagonal quasilattice

    The construction of a two-dimensional tiling by a specific projection of three-dimensional cubic lattice is considered. Different a periodic tiling’s, consisting of equal rhombi, are obtained by different choice of the projection region. They are ordinary a periodic tiling, having local elements of symmetry group С6v and chiral trigonal stacking, built like chiral pentagonal Penrose’s quasilattice [1], which occurs in virus cap sides.

    Keywords: Quasicrystal, quasilattice, two-dimensionalquasicrystal, chiral quasicrystal.

  • Priority planning processes of information in the CAM

    The article examines the construction of control plans and priorities ranks of information procedures for the implementation of the optimal information management in an automated information system. Constitute the basis for planning the hash ranks and priorities of both the subjects and objects of information interaction. The optimization process is provided by a choice of grades and corresponding control plans that define the extreme values ​​of the objective function of the system.

  • Study of the dynamics of washing machines in the spin cycle

    The questions devoted to the study of influence of mass textile articles vibroaktivnosti drum type washing machine with a horizontal axis of rotation at a centrifugal spinning. Feature of research is accounting change in mass production during the spin cycle when calculating the amplitude of transverse vibrations, including during acceleration and passing the resonance zone. The object of investigation used a modern model of household washing machine. Initial operating parameters were varied, based on the actual values ​​for the machines of this type. In a paper on the study the graphs, the analysis of the data obtained. The results can be used to study the dynamics of washing machines to improve their vibration isolation systems.
    Keywords: Washing machines, dynamics, vibration amplitude, the influence of mass products.

  • Arrangements of computational intelligence in solving the automatization problem of prediction of electricity

    In this paper we consider the problem of effective forecasting of electricity consumption for multiple objects in automatic mode. We propose an approach to automation of forecasting process, based on CRISP-DM. There were considered methods of computational intelligence for the data preprocessing - filling the gaps and identification of the emission, methods of construction and adjustment of forecasting models. As the computational basis are used connective models, based on neural networks and on constructive neural networks. There was shown the system architecture that implements the mechanisms of computational intelligence, and was presented the results of the tests.

  • Modeling Dynamic Violence: Adaptive Agent-based Models

    This article presents an agent-based computational model of civil violence. In the model we present variant of civil violence when central authority seeks to suppress decentralized rebellion. This model involves two categories of actors. ‘‘Agents’’ are members of the general population and may be actively rebellious or not. ‘‘Cops’’ are the forces of the central authority, who seek out and arrest actively rebellious agents. Both type of actors are having attributes and behavioral rules.
