    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

  • 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.
