    Ryvkin S.E.Estimation of State Vector Components in a Nonlinear Singular System (pp. 8-13)

    Abstract. The sufficient observability condition is formulated and proved for a class of nonlinear dynamic systems linear with respect to the estimated subvector of the full state vector. Nonlinear estimation techniques for state variable components based on slide modes are offered. The methods efficiency is shown by the example of the estimation algorithm synthesis for mechanical variables of a synchronous motor.

    Anisimov D.N., Khripkov A.V.Distribution Laws of Dynamic Objects Parameter Estimates in the Identification by Exponential Modulation Method (pp. 14-18)

    Abstract. A new method of dynamic objects identification named the Exponential Modulation Method is considered. The paper shows that the method can be easily realized and features high noise immunity. The problems related with the selection of optimal input signal are discussed. The distribution laws of the estimates under the disturbances such as white noise and sine wave with random phase are determined.

    Information Technologies in Control

    Alexeevsky M.V. Integration And Globalization of Data Processing Software (pp. 19-23)

    Abstract. An effective method for solving the problem of globalization and integration of separate corporate software into in unified information system is discussed. The method presumes the transition to the three-tier network architecture Client → Provider → Server using the software toolkits of COBRA/KORINF technology.

    Alguliev R.M., Alyguliev R.M.Ranking of Web Pages Using Mutual Information Between The Hyperlinks (pp. 24-29)

    Abstract. To improve Web pages ranking efficiency, the paper offers 3 modifications of PageRank algorithm. The first one features the measurement of hyperlink independence degree for calculating the hyperlinks weight. The second and third ones considering the thematic affinity of Web pages are the improved versions of algorithms WPR and Topic-Centric respectively.

    Zatuliveter Yu.S., Fischenko E.A.PS-2000 Multiprocessor Architecture on a Chip (pp. 30-35)

    Abstract. The contemporary problems of building multiprocessor architectures on a chip are examined. The paper suggests to develop the architecture well proven in domestic PS-2000 multiprocessor computing system for the realization on a chip.

    Vasiliev I.L., Sidorov D.N.Cluster Analysis Application to Automatic Flaw Detection (pp. 36-42)

    Abstract. The problem of automatic detection and categorization of flaws that arises in machine vision system development is discussed. A method of its solution is proposed. At the first stage, an autonomous process of system learning is performed where the learning samples of the analyzed flaw symptoms are split into clusters with medians. At the second stage, the real-time inspection process is performed where each incoming pattern is categorized according to the nearest median type. The paper notes that the comparative analysis against other techniques showed the effectiveness of the method proposed.
    Control in Social and Economic Systems

    Abstract. A numerical-expert procedure for evaluating the contribution of departmental target programs into the accomplishment of Russian Federation governments goals is offered for developing the list of such programs financed from the national budget.
