  • 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.

  • 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.

    Keywords: consumption of electricity, forecasting automation, computational intelligence, identification of the emission, connective models.

  • 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.

  • Study of the growth of ZnO nanorods carbothermal synthesis method for thin film sublayers ZnO: Ga

    Carbothermal synthesis method on substrates of a-Al2O3 thin film with sublayers ZnO: Ga, using copper as a catalyst for the arrays obtained by varying the zinc oxide rod morphology. It was established that growth of the rods occurs direction perpendicular to the substrate using a thin (~ 1 nm) layers of the catalyst. With increasing thickness of the catalyst layer to 3 nm rods growth occurs at an angle to the surface of the rod with a mutual orientation in the plane of the substrate surface at angles that are multiples of 60 °.

    This paper presents an analysis of the dynamics the emotional component of the group political installation installation by results of the researches carried out among students in RSCUbetween late 2009 and early 2011 by method of semantic differential. It’s shown the dynamics the average semantic portraits and designed for them the emotional level of perception of the political order. Emotional level’s are determined by the relative proximity of images the real order to images of an ideal positive and negative order, in the linear approximation in the framework of previously developed psychosemantic phenomenological model. It’s received lowering the level of perception during the study period from -0.1 to -0.3, that indicate the increase in political tensions among the respondents.
