The criteria for selecting the optimal type of Wavelet analysis are analyzed to increase the accuracy of identification of non-sinusoidal voltage distortions, because this technique can determine the amplitude, frequency and time (duration) of the presence of harmonics in current and voltage signals. This information will be useful in assessing the technical and economic effect of the introduction of filter-compensating devices to determine the harmonics and reduce losses.

It is shown that electrical cable systems used in mining areas experience heavy loads from their own weight, and can also be subjected to mechanical damage as a result of shifting rock layers. This leads to emergency situations at mining enterprises, which threatens the maintenance personnel lives. To compensate for tensile stresses leading to wire breakage, extension sleeves of various designs are installed on the cables. A study was made of loading schemes for sleeve flat and shell elongating elements, which showed that the shell element is a more effective component. Due to the calculation and selection the element cylindrical stiffness and of the meridian inclination angle to the symmetry axis, the best elongation effect can be achieved.

There is a steady trend in the mechanical engineering industry to increase the required accuracy of parts manufacturing using high-speed equipment. The control of such equipment requires consideration of the motion differential characteristics such as velocity, acceleration, and jerk. However, due to the discrete nature of the incremental encoder operating as a pulse generator, estimation of these characteristics requires the use of special data processing methods. Considered encoder resolution limitations and proposed a method for determining the discreteness providing the maximum possible accuracy of position measurement. Discussed methods of the velocity estimation using incremental encoders. Determined the required sampling frequency of the time counter. The use of CNC-based software and hardware complex for the study of the velocity estimation methods is proposed. Results of experimental investigations confirm the possibility of acceleration estimation and demonstrate problems with jerk estimation. Analysis of the error sources in the measurement of differential characteristics is performed. Topical areas for further research is proposed.

Detection of pixels to real-world unit correspondence on the image is an important step for the further analysis of the geometrical characteristics of the objects on the image. In this paper, I propose an iterative method of automatic identification of the ruler scales on the image based on digit recognition. Experiments showed a mean absolute error of 6.63 px and median absolute error of 4 px on high-resolution images $(3104mathrm{x}1746 text{px})$ compared to the manual measurement results. I focus on the medical domain images, but this method can be used in many others domains like forensic, museum business, etc.

The development of multi-cloud systems with an acceptable level of service delays that significantly affect the quality of the end-users experience is an open research problem, for which simulation is successfully used. This paper proposes a simulation model in Matlab for estimating the time to write data updates initiated by the end-users to the databases of all cloud service providers for a multi-cloud system with a geo-distributed middleware that implements, as an example, the VIP-grab data consistency protocol. The simulation results indicate that our model can be useful in choosing a data consistency protocol that influences the architecture of a multicloud system.

Unauthorized use of unmanned aerial vehicles (UA Vs) for surveillance of important objects, carrying out terrorist attacks and sabotage, throwing prohibited objects (weapons, drugs) has updated the search for cost-effective and technically feasible solutions to counter UA Vs. An analysis of materials on this topic showed that the effectiveness of defeating all types of UA Vs by existing means of air defense and electronic warfare is quite high. However, the problem of countering small UA Vs, based on the experience of the war in Ukraine, is not resolved. The purpose of the article is to analyze the UA V, as an object of detection and countermeasures, using acoustic means of airspace control with minimal economic costs. The article presents the results of the analysis of the UAVas an object of detection and the issuance of target designations by means of acoustic observation.

Shop floor power supply systems must meet stringent requirements for high reliability and efficiency. Trolley's busbars are an important element of the power supply system. Currently, engineering methods are known that allow to determine the resistance of trolleys. But they have a high error, since they do not take into account the surface effect, skin effect, proximity effects, edge effects, as well as the higher harmonics of the current in the network. In this paper, an approach is proposed that allows to determine the resistance in the trolley's busbars with high accuracy. This method is based on the application of the decomposition of electromagnetic processes in a trolley's busbars. The method implements the inclusion of one of the phases of the busbar to determine the resistance without the influence of an external magnetic field. As well as two phases of the busbar to determine the active resistance in the presence of an external magnetic field caused by the action of a third-party current of the neighboring trolley's busbars. The paper presents dependences for determining the values of resistance for the corresponding phases and harmonics of the current without spending time on field modeling. And also, regardless of the location of the trolleys, their number, shape, as well as the non-symmetry of the phase currents.

The multi-step process of structural-parametric identification of mathematical models of control objects according to the principle of rational complication is considered. Identification specifies the mathematical model of the object and methods of its identification in the process of accumulation of a posteriori information. The quality of multi-step structural and parametric identification of an object depends on the amount of a priori information that grows after conducting experimental studies. For a qualitative solution to the problem, it is necessary to rationally complicate identification methods after analyzing the results of the previous identification step. Examples of application of the proposed principle of rational complication are given, which show its advantages in comparison with classical methods.

Viscoelastic deformation cycles of human blood vessels under normal functioning conditions were studied. Atherosclerotic plaque with stochastic development was also taken into account in the modeling. A computer simulation algorithm has been developed to perform parametric analysis for models with different geometrical dimensions.
