The comparative thermography analysis of temperature during machining by turning was presented. For the tests cast iron EN-GJL 250 and stainless steel 1.4301 were used. The machining by turning was performed with the TNMG 220408HS PC9030 and TNMA 220208 NC6210 cutting inserts design for machining that kind of materials. The temperature was measured on the machined material and ...

Eddy current loss (ECL) in underwater wireless power transfer (UWPT) systems can significantly affect the efficiency of underwater vehicles. This study provides comprehensive modeling of the eddy current effects in circular planar coils. The analytical model has been extended to any number of transmitter and receiver coils’ turns exposed to different conductive regions, providing ...

This research considers the application of a multi-criteria approach to assess the quality of textbook content. The issues of determining evaluation criteria and organizing the work of experts are brought to the fore, as these factors directly affect the objectivity and efficiency of the evaluation process. The definition of criteria consisted of reviewing common mistakes ...

In order to ensure optimal operation of the existing environmental monitoring information system, it has become essential to use mathematical modeling based on the data assimilation algorithm. In this paper, a data assimilation algorithm has been designed and implemented. An algorithmic approach was tested for the assimilation of city atmosphere monitoring data from an ...

In the era of increasing climatic requirements and changing approaches towards circular economy (CE), the demand for materials designed with care for the environment is growing. This idea is especially important in the construction industry, where ordinary Portland cement (OPC) production emits a large number of greenhouse gases. The main aim of this article is to demonstrate ...

The paper studies the problems of developing interconnected models of aggregates of complex chemical-technological systems (CTS) in conditions of scarcity and fuzziness of the initial information. Since the known methods of model development do not allow for solving these problems, we propose a systematic method that allows the development of a package of models of interconnected ...

Electronic voting, based on cryptographic protocols and blockchain technology, represents an advanced method for ensuring the security, transparency, and reliability of electoral processes. The scientific research presented in this article is devoted to the analysis of trends and advanced technologies in the field of electronic voting. The authors propose a systematic mapping ...

Consider the problem of determining the coefficients in the differential equation of parabolic types and boundary conditions on the known sections of the solutions of the initial-boundary value problem. Used spectral approach based on spectral properties of the elliptic operator of the initial-boundary value problem and the methods of solving the inverse spectral problem of ...

Magnetic Resonance Imaging (MRI) is vital in diagnosing brain tumours, offering crucial insights into tumour morphology and precise localisation. Despite its pivotal role, accurately classifying brain tumours from MRI scans is inherently complex due to their heterogeneous characteristics. This study presents a novel integration of advanced segmentation methods with deep learning ...

The aim of this research is to reveal the views of primary school teachers, students and parents on distance education activities during the Covid-19 pandemic period, in order to evaluate the adaptation of students to professional activities through innovative technologies. This research was carried out in qualitative research designs in accordance with phenomenology. The data ...
