Item type:Наукова стаття, Prospects for the development of blockchain technology in corporate information systems(2025-05-27) Tulashvili, Yuriy; Lukianchuk, Iurii; Kosheliuk, ViktorOver the past decade, blockchain technology has undergone rapid development and is recognized as one of the pivotal information technologies driving industrial transformation. Today, blockchain technology offers a promising solution to the problems faced by corporate information systems. Namely, with the help of appropriate measures of anonymization and preservation of confidentiality, the blockchain enhances data security, reduces the risk of unauthorized access, and ensures user privacy in corporate systems. Blockchain technology increases transparency, allowing users to monitor and verify the content of information, assess the integrity of data stores. In recent years, blockchain has become a subject of interest for state governments, multinational corporations, and major financial institutions. Today, considerable attention is paid to the development of private (corporate) blockchains. This article examines the prospects and development of blockchain technology in corporate information systems. The study is aimed at providing additional clarity regarding the concept of blockchain applications in corporate information systems. Existing enterprise applications cannot operate seamlessly with traditional transactional requirements when integrating blockchain technology. Therefore, they will have to be modified with inclusion in the existing data storage for asynchronous interaction with distributed nodes of the blockchain. A scheme of the principle of interaction of nodes-storages that support data synchronization and their current states are proposed. This scheme is based on a blockchain structure centered around cloud storage as a corporate document circulation system. Consensus to include a new entry-Byzantine fault tolerance. Blockchain nodes receive a parametric weight for decision making.Item type:Наукова стаття, 3D Model Quality Assessment Algorithm for Additive Manufacturing(2024-10-27) Marchuk, Viktor; Tulashvili, Yurii; Lukianchuk, IuriiIn modern production, problems arise when modeling 3D objects using the FDM method. Among the common mistakes are insufficient attention to the geometry of the object, insufficient calculation of the thickness of the walls and details. An algorithm for analyzing the manufacturability of parts before the start of production can help avoid many problems. Determining the optimal print direction, support placement, and heat distribution are key steps that help ensure the highest manufacturing quality. It is also important to emphasize the use of mathematical calculations during design. Calculating the amount of material required, optimizing geometry to minimize weight and maximize strength are just a few examples of how math can facilitate the process. Careful advance planning and the use of advanced analytical methods can significantly improve product quality and reduce production errors. Recommendations provided at various stages of design and production create an opportunity for engineers to avoid common problems and ensure the successful implementation of projects in the field of additive manufacturing.Item type:Наукова стаття, Didactic Principles Of Education Students 3D-printin. IJCSNS International Journal of Computer Science and Network Security(2022-07-26) Lukianchuk, Iurii; Tulashvili, Yurii; Podolyak, VolodymyrThe method of studying 3D-technologies abroad and in Ukraine is considered. The analysis of educational resources and experience of use of the equipment in branch is carried out. The didactic principles of the educational process for 3D-printing specialists are determined. The use of FDM technology and the ability to minimize the occurrence of defects in the future have been studied. An analysis of the international experience of the educational process of relevant specialists in the field. The content of training for 3D printing specialists has been developed. The experience of using 3D-technologies is described and the list of recommendations for elimination of defects during production of products by means of additive technologies is made. The recommendations will be useful not only for beginners, but also for experienced professionals in additive technologies. The need to study such experience is the main condition for the development of enterprises in Ukraine that plan to automate their own production. A 3D printing engineer must know the basics of economics and marketing, because his responsibilities include optimizing workflows to reduce the cost and speed up printing. Therefore, the knowledge gained from practical experience presented and in building for learning 3D printing engineers by the authors will be important.Item type:Наукова стаття, Program Implementation of Educational Electronic Resource for Inclusive Education of People with Visual Impairment(2023) Tulashvili, Yurii; Lukianchuk, Iurii; Lishchyna, Valerii; Lishchyna, NataliiaIt is substantiated that the educational software used in the educational process during the computer training of visually impaired people contributes to the formation of their correctional and compensatory devices for the use of computer technology. The peculiarities of the inclusive educational process of professional training of persons with visual impairments with the use of computer technology are pointed out. The architecture and features of creating educational software for the visually impaired are revealed. A mathematical model and algorithm for its implementation of educational software for support of inclusive educational process of professional training of persons with visual impairments have been developed. The developed training software presents the theoretical content of training in an adapted form. The developed practical tasks contain an exhaustive list for the formation of correctional and compensatory devices and the acquisition of skills and abilities to use computer technology for people with visual impairments.
