  • Analytical determination Waybill distribution parameters for final volume population according to durability of steel selective data

    The analytical method determination parameters of the three-parametrical Waybill distribution for final volume population on the basis received parameters on a sample is stated in this work The algorithm of calculation on which computing experiment is made is presented. On the basis of these calculations the conclusion that it is necessary to determine by this analytical method parameters of the three-parametrical law of Waybill for set of final volume on the basis of the received parameters on a sample is drawn.

    Keywords: population of final volume, sample, dispersion, an average quadratic deviation, distribution parameters, durability became

  • Level of a group political tension in the student's environment of Rostov-on-Don for 2011

      Results of the flight research spent in student's RBSU environment in December, 2011 are presented. The method of semantic differential is put in a basis of questioning. Respondents were offered to estimate four types of a political order by using of 20 double modal seven-ball scales. Two "ideal" orders are as much as possible attractive order and as much as possible unattractive one. And two real orders are the political order existing in Rostov region and a political order in Russia as a whole. The estimation was spent in linear approach, and also in frameworks the early developed phenomenological model considering typical nonlinearity, which is probable for a considered case. It is received, that in the end of 2011 students were characterized by negative perception as political order in area (with level -0.7, a level was normalized from +1 to-1), so an order in Russia in whole (with level -0.77). Surfaces of the stationary states, allowing to detail dynamics of change of perception level are calculated. Comparative dynamics of behaviour of emotional perception level of real political orders from the end 2009 on the end 2011 is presented. 

    Keywords: questioning, semantic differential, political order, emotional perception level, typical dependence, nonlinear approach, catastrophe theory, dynamics of change of perception

  • Prospects of development of the market of information services in the region

    The article deals with research problems, tendencies and directions of development of the market of information services in the context of a specific region, Stavropol territory. Expanded categorical apparatus of the sphere of services based on the impact of information services on the development of all kinds of activity in sphere of services. Designed on the basis of the situational approach, the mechanism of control of the market of information services, contributing to the transformation of external and internal to the subject of management of information and knowledge in information goods within the borders of its current or future needs, tactical, or strategic interests.

  • About margin of safety and an assessment of reliability of knots of a metalwork

    The stochastic model of an assessment of mechanical characteristics of strength on the basis of the analysis of function of reliability is offered. Communication of function of reliability with normative factor of safety factor is correlated. Recommendations to destination mechanical characteristics of strength on Gauss to a level and factors of a variation are given. Analytical and graphic dependence for optimum purpose of parameters of reliability of units of hardware on the lead strength researches is offered.

    Keywords: Strength, reliability, factor of a stock, mechanical characteristics, the likelihood analysis

  • 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.

  • 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.
