Industrial power consumption cost-benefit analysis requires reliable data on the electric power amounts distributed between manufacturing departments and process units. Furthermore, reliable power consumption data provide the base for fiscal cost clearing at electric power markets. These data are supplied by the electric power measuring systems (counters) the failure of which results in the gross...
The paper considers application of methods for the uniform approximation of functions to find the polynomials of the approximation of sensors' inverse conversion functions. It suggests an iteration algorithm to implement the weighted uniform approximation of the dependency of the sensor's exit code on the ambient temperature. The experimental data were used to demonstrate the efficiency of the offered...
The article is devoted to the study of the existing methods and solutions of non-intrusive methods for flow parameters measurement. The literature sources with various types of measurement instruments used to measure the flow parameters were studied and reviewed. The theoretical materials on non-intrusive methods and device implementation examples are presented. The method for combination of the measurement...
The aim of this paper is to develop the theoretical basis of mechatronic systems construction using the principal components projection method for conducting natural model measurements of mechatronic systems parameters. It is difficult to name a technical sphere where mechatronic systems aren't applied. They can be found in many household appliances, communication devices, they make an integral part...
The authors conducted a theoretical and pilot research of the physical phenomenon of a charging decompensation in the course of explosive formation and plasma warming up. This physical phenomenon cannot be described within relativistic electrodynamics. Its existence is predicted by hyper continual electrodynamics. It relies on the hyper continual ideas of space and time within which transition between...
The paper presents a mathematical model of a piston compressor which is a part of an oxygen gas generator. Taking into account the structural parameters of the compressor, as well as the suction and pressurization valves, such model allows one to obtain the dynamics of the pressure amplitude under the compressor's piston with the vibration velocity and vibration acceleration that are transmitted in...
The paper provides the mathematical model describing the movement of different kinds of avalanche snow mass and its interaction with obstacles based on the modified method of particle dynamics. Further, the authors introduce their algorithm to calculate avalanche impact on buildings and structures; this algorithm underlies a computer program that allows you to set the basic parameters of a building,...

The evaluation of the sustainability of an information structure security system in terms of negative impacts is initially...
The method for an algorithmic correction of errors in determination of the angle parameters of three-component vector-measuring transducers installation in the body of a measuring device is presented. The factors influencing the metrological characteristics of three-component vector-measuring transducers with accelerometers are reviewed. The methods to reduce the errors defined by the constants characterizing...

The paper deals with the processing of information on the state of a computer system using probabilistic automata. An intelligent system model for the detection and classification of malicious software is proposed which compares a set of features that are characteristic for different classes of viruses with multiple states of the machine. The analysis process is reduced to the modeling of the automaton...
Neural networks along with expert adaptive regulators and systems with associative memory form the basis of intelligent technologies for information management and processing [1], [2]. This paper introduces an algorithm for the dynamic measurement error correction based on a neural network (NN) inverse model of a measuring transducer (MT). It uses the reduction principle in the compensating filter...
In this paper an approach to information quantitative measuring is offered. This information is given as a fuzzy number. It is a particular case of the fuzzy set which is defined by a membership function. It should be noted that this function is determined on the basis of some segment on the set of real numbers. Therefore, a problem changes into construction of the fuzzy number membership function...
One of the important things in the dynamic measurements theory is the task of dynamically distorted signal restoration. The existing algorithms demand a bigger amount of machine time. In the project the numerical algorithm of the optimum dynamic measurement problem solution with the use of parallelization and linear splines is presented. A distinctive feature of the algorithm is that one was able...
The paper considers an important practical problem of the crystal phonon spectrum determining by the heat capacity dependent on the temperature. The problem reduces to an integral equation of the first kind solvable by the regularizing algorithm. This algorithm involves finite-dimensional approximation of the original problem and allows reducing the problem to a system of linear algebraic equations...
The main concern for many applications (for example, for Coriolis Mass Flow Meter signal processing in two-phase flow conditions) is to track several domain poles of signals with minimum delay. The Matrix Pencil method (MPM) estimates the signal as a sum of complex exponentials. Creating a computationally efficient moving MPM implementation is of a high interest. The most computationally expensive...
The possibilities of implementation of Markov model of radio signals with various types of modulation at the output of the radio transmitter are considered. Markov models of Gaussian random processes are studied. The properties of the obtained models are analyzed. For their graphic description, three-dimensional representations of matrices of joint and transition probabilities are proposed. The properties...
