The two approximate methods of choosing the rational strategy to search and correct a fault on the Markov chain model base with a game-theoretic definition of the unknown transition probabilities is proposed. A comparative analysis is completed.

Keywords: Markov chains, game-theoretical optimization, matrix games.

The article deals with sonar communication channel, its characteristics, factors affecting the distribution of hydro-acoustic waves in the ocean environment. For video data compression methods are considered digital imaging and design of proposed systems for transmission of digital video signal and a block diagram of the ADC.

Keywords: sonar, hydroacoustic communication channel, the acoustic wave, high-speed ADC.

Offers intelligent method of assessing the reliability of data (verification), in databases, based on the theory of artificial neural networks. The method consists of three steps: data clustering using the Kohonen network, training radial basic network and its computation using the validation database table rows. To create a radial basis networks and their training Backpropagation developed software tool. The proposed verification method of data can be used in various applications of information systems.
Keywords: database, relational algebra, verification, radial basis neural network training neural networks, Kohonen networks, clustering.

This article discusses a method for calculating the combined diagnostic feature called spectral signature, based on the use of mathematical apparatus Walsh transformations for logic functions and differential logical calculus. We consider a class of devices which can be implemented in the proposed method. A method for determining the spectral signatures for discrete devices differs from the known methods of diagnosis less computational complexity and allows the implementation of a self-test in the operation of devices.
Keywords: spectral testing, signature analysis, technical diagnostics, information and control systems.

In this paper, a comparative analysis of the shift parameter distribution initial set of calculated analytical method and simulated, obtained by computer simulation using sample data. Error δi shifts between the parameters listed in the table and plotted errors on the scope and volume of the aggregate.
Thus, increasing the volume of the aggregate error is reduced from 30% to 1% at a constant volume sample m = 50.
Keywords: sampling, aggregate, volume, range, accuracy, distribution, performance analysis, engineering, reliability.
