The latest methods and technologies, namely their effective implementation a priori becomes impossible without the use of superhard materials. This is especially critical for tool production in the machine-building industry. Therefore, the use of this group of materials requires the development of new and improvement of existing progressive methods for processing these materials...
The main parameters of diffusion welding and the features of their control methods are described. It is shown that, under conditions of diffusion welding with heating of parts in a glow discharge plasma, traditional methods of monitoring the temperature state of the welding zone such as thermocouples and optical pyrometers become insufficiently effective due to interferences...
The development of natural systems on the planet is characterized by the growth of human society's potential in line with its needs and the challenges facing the surrounding environment. At the same time, evolution through natural selection is random, and millions of mutations occur, of which only a few prove to be useful. As a result, the mechanism of evolution through natural...
In modern manufacturing conditions, a key criterion for production quality is achieving the desired part within the shortest possible time and with minimal production costs. Therefore, the study of the influence of the sequence of technological operations and the selection of machining parameters is highly relevant and enables optimization of manufacturing processes. The...
The relevance of the study is determined by the need to establish a unified comparative framework for evaluating methods of satellite image quality enhancement, since their accuracy directly affects the results of image interpretation, cartographic production, land cover monitoring, and cadastral analysis. Despite the availability of numerous approaches, there is still no...
Archival cadastral maps still have significant potential and are used for many purposes, including research into the social and economic circumstances of changes and reconstruction of land use. Land use is a kind of landscape indicator, as it reflects the close connection between humans and nature and at the same time has a strong and clearly defined temporal dimension. A better...
The State Land Cadastre (SLC) is a basic element of the land management system and property rights enforcement in Ukraine. Martial law, imposed as a result of a full-scale invasion, has significantly complicated the stable functioning of the cadastral system. To stabilize land relations, under martial law, legislative changes were introduced that ensured the restoration of the...
The article examines the implementation of a next-generation electronic geodetic network as a fundamental infrastructure for maintaining the cadastral systems of territorial communities in the context of decentralization and the digital transformation of spatial management. The study considers the technical, organizational, and social aspects of creating and operating these...
The paper presents the results of an experimental study on the accuracy of determining the north direction using various types of magnetic compasses that differed in design, mass, length of the magnetic needle, damping, and manufacturing quality. The main objective of the study was to quantitatively assess the influence of the instruments’ structural features and the user’s level...
The reconstruction of existing highways often requires the insertion of transition curves on curved sections to reduce the negative impact of centrifugal acceleration. The introduction of a clothoid leads to the displacement of the circular curve toward its center, while the options that preserve the position of the center of the circular curve do not account for the occurrence...
