The use of various associated features in evaluating the form and location of surfaces and axes of engineering components leads to significant differences in the values of the deviations obtained. Analysis of this influence, advantages and disadvantages of individual types of associated elements, as well as a criterion for their selection is considered in this paper.
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...
The application of single crystals in acousto-, opto-, micro — and nanoelectronics defines strict requirements to crystals and crystal elements as well as the need for certification of these products. The use of single crystals in acousto-, opto-, micro — and nanoelectronics defines strict requirements both to crystals and crystal elements, and it concurrently defines the need for the certification...
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...

In this article the authors analyze the relevance of intelligent sensors use. The review and classification of the functions of intelligent sensors and systems is given. Structural diagrams for an intelligent measuring system of magnetostrictive linear displacement sensors are considered. There are two ways to implement the self-calibration function, with mathematical control points and active control...
The paper describes a new scalable algorithm called NSLP for high-dimension, non-stationary linear programming problem solving on the modern cluster computing systems. The algorithm consists of two phases: Quest and Targeting. The Quest phase calculates a solution for the system of inequalities defining the constraint system of the linear programming problem under the condition of the input data dynamic...
The article is dedicated to the investigation of adequacy of a new conversion function model for a vortex sonic flowmeter, proposed by the authors using the Monte-Carlo method. The Monte Carlo method is a numerical one used for solving mathematical problems by modeling random variables. During the study, the parameters of the data simulating the measuring information of the vortex sonic flowmeters...
The article deals with set-valued state estimation for linear dynamical systems. Set-valued estimation consists of a construction of feasible sets, which are guaranteed to contain all state vectors. The known set-valued state estimation algorithms include performing set operations like Minkowski sum and set intersection, those are computationally complex. Feasible set approximation with canonical...
The accuracy and productivity of measurement performed with the help of coordinate measuring machines depend not only on their technical characteristics but also on the strategy used to select the number, location of the points and the sequence of their circumvention on the surface. The article proposes a new strategy for the determination of the number and location of control points on surfaces based...
The paper aims at improving the accuracy of the calibration of strapdown inertial navigation systems (SINS). The calibration is carried out using a 2-axial motion simulator. A new computational method is investigated for the calibration coefficients of the error models of accelerometers and gyroscopes of the strapdown inertial navigation system based on the errors of the system output signals. The...
The article considers an unconventional way of analog-to-digital conversion (ADC) of current signals conveyed by the sensors based on the application of the properties of the linear analog current adder (ACA). The authors give the main equations, the ACA circuitry as well as the results of its computer simulation which show that the k-valued code is output current signals of the ADC of the considered...
This paper is dedicated to one of the promising directions in the development of aircraft air data systems that provide information about the altitude and airspeed parameters. The issues of the required air data measurement error as well as of further conversion of the measured air pressure by the pressure sensors are considered. In connection with the trend of eliminating of movable vane aerodynamic...
The article is devoted to the problem of instability of a liquid film flowing over a solid surface under the gravity action. The mathematical model of the condition of the free surface taking into account the heterogeneity of surface tension and shear stress is presented. The results of computational experiments on the wave characteristics of liquid film and areas of instability under the influence...
The article is devoted to the measurement challenge associated with identification of the unknown time-dependent internal heat source when measuring is possible only at the one end of a rod. The required source function in this problem must be determined from the results of indirect temperature measurements. To solve this problem, we propose the approach that allows us to describe the explicit dependence...
An inverse boundary value problem is considered for a non-linear parabolic equation. Two-sided estimates are obtained for the norms of non-linear operator values in terms of the norms of values of the corresponding linear operator. As a consequence, two-sided estimates are established for the modulus of continuity of a nonlinear inverse problem in terms of the modulus of continuity of the corresponding...
