Intelligent construction based on wireless networks and constant connection to the Internet is becoming more and more popular. In the case of wireless communication, it is necessary to take into account not only the demand reported by the constructors of new facilities, but also the modernization of the infrastructure that has been existing for many years. The problem is assessing the...

We propose a method for improving classification for faults detection in electrical machines when the training data contains a significant amount of wrongly labeled inputs. The proposed method uses the ROCKET - fast and accurate time series classification using random convolutional kernels model logits as an input for classical classification models (neural networks, SVC). The logits from...

A mathematical model of an induction motor with a squirrel-cage rotor is proposed that takes into account the saturation of the magnetic system and the current displacement in the rotor bars. In order to take into account the saturation of the main magnetic flux, the main magnetisation curve is used. To take into account the current displacement, the bars along with the short-circuited rings...

An electric drive based on the wound rotor induction motor (WRIM) needs to be optimized. The inclusion of additional resistances in the WRIM rotor circuit is used not only to regulate the motor current and torque during startup, but also to control the rotor speed. The efficiency of an induction drive can be increased by optimally selecting the parameters of the rheostat resistances and the...

A high-performance system for stabilizing the consumption mode of reactive power of an arc furnace (AF) has been developed. The system operates using the principles of thyristor control of the equivalent inductance of the chokes included in the primary circuit of the furnace transformer. The dependencies of the artificial external characteristics of the arc furnace for multicriteria optimal...

Abstract—Peculiarities of the use of parallel computing for the analysis of dynamic systems are studied using the example of the Lotka-Volterra "predator-prey" model. Such relaxation methods as the Jacobi, Gauss-Seidel, SOR and their parallel implementations using Python libraries are considered. The analysis of the efficiency and accuracy of these methods, and the influence of the model...

This paper presents an original implementation of a Particle-in-Cell (PIC) solver with Monte Carlo Collisions (MCC), fully parallelized on CUDA GPUs and developed entirely in the Julia programming language. By leveraging Julia's capability to write CUDA kernels natively, this implementation effectively addresses the "two-language problem" commonly encountered in high-performance computing. The...

This paper presents a comparative performance study of an equilateral triangular patch antenna (ETPA) with and without an additional air gap substrate. The proposed antenna covers the S-band (2.4GHz-2.5GHz) for satellite communication. The antenna consists of truncated equilateral triangular patches connected at the truncated corners by two PIN diodes to the two parasitic triangular patches. A...

Our paper deals with designing and implementing methods for interactive visualization of dynamic spatial data using augmented reality (AR/XR). The data include the work zones of the robots and other information about the environment, e.g. lidar ranges and physical fields are also planned. Visualization takes place using AR headsets Microsoft HoloLens 2. These headsets are equipped with our...

Industrial high-temperature applications have traditionally depended on fossil energy sources, which are inherently inefficient. Consequently, there is significant interest in exploring efficient and sustainable alternatives. Induction heating technologies, known for their energy efficiency, can be powered by renewable energy sources. This study presents and models a device designed for...

The article discusses the practical application of the inverse method of electromagnetic non-destructive investigation of austenitic materials. It includes the design of a robust tool for the automated localization of material defects. To identify and evaluate deep artificial defects, the sweep-frequency eddy current method with harmonic excitation is used. The objects of interest are surface...

X-ray imaging systems are among the oldest and most widely used imaging systems in medical and industrial diagnostics. X-ray imaging systems have changed considerably over the course of their existence. The physical principle remains unchanged, but the technical means of image acquisition have been replaced. Today, in addition to conventional X-ray imaging machines, digital machines and CT...

The purpose of the article is to investigate electromagnetic field exposure a person with an implanted device experiences when using a mobile phone in the DCS band. This study will involve measuring, analysing, and quantifying RF-EMP exposure to understand its impact on EMF distribution and to identify potential health risks for people with implantable devices. The measurement results are...

The paper is focused on computer simulations related to the extrusion of ceramic material for continuous 3D printing. The aim is to optimize the process of extrusion of ceramic material using numerical simulations. These simulations are essential for understanding fluid dynamics in 3D printers, especially when working with complex materials such as ceramic clays and clays with additives. The...

In this study, we aim to create a model of the human eye and antenna to simulate the impact of high-frequency electromagnetic fields (EMF) on it. Our objective is to compare the calculated results with the current legal limit values for high-frequency EMF and their interaction with the tissues of the human eye.
We utilize assembled simulation models that combine specifically designed dipole...
