  • Intelligent semantically oriented approach to automation travel agency work

    At this paper we propose a new approach to processing knowledge through intelligent automation system travel agency. This approach is based on models of knowledge, interpreted using semantic knowledge. The principles of construction and operation of the architecture of the system to automatically obtain and process context information as an example of intellectual semantically-oriented system that provides travel services. Completed description of the ontology used by the tourist area. Demonstrated the use of context information from the knowledge base in the processing of queries to the system.

    Keywords: ontology, automation of a travel agency, intelligent, contextual data, behavioral design patterns

  • Research of tension near flat horizontal cut

    An accurate solution of problem for a plane horizontal cutout is proposed where stress concentration subject to geometrics of the cutout is considered. This solution makes possible to solve problems relating to optimum designing of structures and machinery with similar technological elements.

  • 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.

  • Developing an algorithm of fuzzy adaptive management project metadata

    Based machine adaptation developed an algorithm that adaptively adjust the parameters of the membership function of design data. Adjustment parameters of the membership function is proposed based on the analysis of the reaction of the designer on the query results. This approach allows you to adjust power supplies design solutions to the corresponding values ​​of logical variables based on subjective opinions of experts consecutive. The presence of a mechanism of adaptation helps to reduce the impact of one-off, drop out of the general concept, opinions.
    Keywords: automatic adaptation fuzzy data correction.

  • 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.
