A method for the multiple faults diagnosis in linear analog circuits is presented in this paper. The proposed approach is based upon the concept named by the indirect compensation theorem. This theorem is reducing the procedure of fault diagnosis in the analog circuit to the symbolic analysis process. An extension of the indirect compensation theorem for the linear subcircuit is proposed. The indirect compensation provides equivalent replacement of the n-ports subcircuit by n norators and n fixators of voltages and currents. The proposed multiple faults diagnosis techniques can be used for evaluation of any kind of terminal characteristics of the two-port network. For calculation of the circuit determinant expressions, the Generalized Parameter Extraction Method is implemented. The main advantage of the analysis method is that it is cancellation free. It requires neither matrix nor ordinary graph description of the circuit. The process of symbolic circuit analysis is automated by the freeware computer program Cirsym which can be used online. The experimental results are presented to show the efficiency and reliability of the proposed technique.

The aim of the paper is to introduce a new approach for the Regions of Required Quality (RRQ) construction under the Control Systems computer-aided analysis and design. Application of the Artificial Neural Networks (ANNs) as a tool in the proposed techniques is represented under the title “Method of Sensitive Border”. The developed Neural network model of the RRQ-region's border allows one to get more available information on the performance indices' behavior in the vicinity of the border. Calculation of recommended value for scanning step norm and performance indices gradient enclosed in the ANNs model (NDM) enables the use of the NDM-model as a source of important information under solving interpolation or extrapolation problems. As opposed to traditional approaches mostly based on approximations through preliminary stored and classified experimental data files, the Sensitive Boarder method exploits the NDM-model as an element of searching procedure via successive experimentation. The theoretical results were applied for the RRQ-regions construction with reference to 320 KW Synchronous Machine control. The obtained regions allowed one to define the best combinations of tunings for provision of the desired levels for appointed performance indices related to output voltage, frequency, power and system stability.

In the modern world, the problem of copyright protection by watermarks and trade preserving secrets is very acute. There is a large number of steganography methods that allow us to solve this problem. The most resistant to statistical attacks are the methods that operate with the frequency domain of the container, but small container distortions lead to an error in the lower bits of the reverse transform. The article presents a method included in the class of the frequency domain methods that embed information into the frequency domain of the cover image. To improve the resistance to transformation errors, noise and compression, we proposed the modification of the DEMD embedding method. For the frequency transformation we used the Hadamard transform, because this transform is orthogonal and operates with integers which results in a smaller error in the reverse transform. Embedding occurs in the high-middle frequency of the container. Based on the results of the audit, the proposed solution proved to be more resistant to errors and preserved information to a greater extent.

The paper considers some features reflected by simulation of electric drives operated in the random load modes. It is shown that the distribution laws for losses and the torque are essentially different. I.e., when modeling random modes of electric drive it is impossible to transfer the distribution law of the motor load, which is characterized by the motor torque, to the motor loss distribution. It is also shown that the value of the standard process deviation can significantly differ from the standard deviation of the amplitudes of this process; the difference can be either downwards or upwards depending on the cyclic duration factor and mathematical expectation of the amplitude. The influence of the torque limitation on probability density functions of load and losses was considered. The distribution law in the absence of the torque limitation and with regard to the impact of these limitations can result in different values of mathematical expectations and variances.

Nowadays we have a project of a high-performance parallel encrypted database on a cluster platform that will work with large volumes of data. For the smooth operation of the system, a reliable and high-speed data replication mechanism is required which should satisfy certain criteria of PostgreSQL DBMS and the mentioned project. In this article we consider the very essence of data replication, replication strategy, the basic methods and techniques of replication and also made compliance analyses with the replication method for high-performance parallel DBMS on the cluster platform. We also made an experiment to study the reliability and speed of the method for data replication between nodes in the cluster where the work was done with different amounts of the replica and a different nodes number. The aim was to obtain information on the speed of the Slony-I replication method at different volumes of the replicated data and the different number of nodes in the cluster on which we make a conclusion about the reliability of this method in relation to the project mentioned above.

The paper proposes the approach for uniform presentation of technical objects and technological processes with a variable structure. This approach is based on the approximation of specific models describing the object or the process by a uniformed remodeling class. The application of this approach is useful while solving optimization and control problems. Neural network models, which proved their high approximating capability, are suggested as a remodelling class. Application of the given approach is considered by the example of inertial torque transformer (ITT) workflow modelling. This process has a cyclical pattern where each phase of the cycle is divided into four segments described by various systems of nonlinear differential equations with the same parameters. Moreover, the solution to the system describing the next segment depends on the solution to the system obtained by the previous segment. It noticeably makes it difficult to determine the optimum ITT parameters as the fit function has the solution to the system of equations describing the last, the fourth segment of the cycle. The neural network model allows simplifying the solution to the given problem for each cycle segment.

The article presents the results of the long-term forecasting for maximal power load daily graphs in the North Tajikistan power system with the use of principal component analysis orthogonal decomposition. The primary data for forecasting are maximal power load daily graphs in winter (January) and summer (July) periods from 2011 to 2015 which provide the data for the data matrix. The orthogonal decomposition of the principal components analysis is performed for uncentred daily graphs. The eigenvectors of the covariance matrix K obtained by the data matrix P make for a single orthogonal basis which performs the mapping and forecasting for both winter and summer maximal daily graphs. Here we have performed the analysis of interrelation between the orthogonal decomposition principal component analysis and the form of the studied power load daily graphs at the specified typical daily intervals (morning and evening maximum, daytime and night hours) by the example of the maximal load registered in the Northern Tajikistan power system. The identified dependencies were used to improve accuracy of the power system maximal load long-term forecasting. The forecast for 2016 was carried out in the framework of the first three principal components by the least-squares method taking into account the expected load growth and interrelations of the principal components with the daily graphs' form. The average relative error of forecasting for January 2016 amounted to no more than 6.5%.

The application of the Wentzel-Freidlin asymptotic method in the control problem of estimating the probability of large deviattions is considered. This problem is reduced to the Lagrange optimal control problem for the action functional. In the case when state space matrix of object is Hurwitz matrix, the existence of a unique solution of the Lagrange problem in the form of quasipotential extremals (QE) is established. Based on QE it is possible to build an effective prediction of critical states of control process. The advantage of this method allows arranging the information on the high level, and thereby, building a control system that is based on knowledge. An example of a seaworthiness control algorithm design for a vessel on-board system is shown. In this case, the proposed method of prediction of the critical state based on the action functional leads to frequency-doubling principle known for the Mathieu equation.

The studied objects of this article are the liquid non-metallic high temperature environments. Many important theoretical and practical technological problems haven't been solved yet, and these environments are the main ones for the area. For example, it hasn't been resolved yet how to achieve a stable position of liquid in the molten bath at a constant current in steel industry. The calculation of electromagnetic forces which play a decisive role in this case usually begins with calculation of the electric potential. The calculating tool is the software Matlab. Computer experiment revealed the significant heterogeneity of potential field on a liquid surface. Although the nature of its distribution on the surface scarcely depends on the Laplacian value, it depends very much on the boundary conditions of Dirichlet and Neumann.
