Публікація A Small-Sized Robot Prototype Development Using 3D Printing(FACULTY OF MECHANICAL ENGINEERING BIALYSTOK UNIVERSITY OF TECHNOLOGY, 2023) Nevliudov, I.; Yevsieiev, V.; Maksymova, S.; Chala, O.The work presents the development of all parts of a mobile small-sized robot, except engines and electronics, using 3D printing technology. For control it is proposed to use ESP32-СAM, for which a place is provided in the design. This will allow the robot to broadcast a video stream via Wi-Fi.Публікація Analysis of Systems for Coordination of Enterprise Subsystems Control(2024) Chala, O.; Maksymova, S.; Ahmad AlkhalailehAny automated production, at the current stage, must have systems or control modules that serve to coordinate the subsystems of the entire enterprise. Control in this case occurs through the use of separate modules responsible for monitoring each individual subprocess. Software modules are being developed for such processes, which combine monitoring and operational regulation under the processes, which allows to one degree or another to reduce the risk of damage or failure of all production links. Thus, the creation of a computer-integrated management system for coordinating the functioning of the subsystems of the enterprise is an urgent and timely task. This paper analyzes the basics of building a production subsystem control system. Algorithms for the operation of such systems are also considered.Публікація Automated System Development for the Printed Circuit Boards Optical Inspection Using Machine Learning Methods(ХНУРЕ, 2021) Nevliudov, I.; Botsman, I.; Chala, O.; Khrustalev, K.The problem of printed circuit boards (PCB) quality optical inspection at their production stage is considered. The automated method of PCB optical inspection on the machine learning methods basis is proposed. The necessary neural network parameters to develop an automated PCB inspection method are calculated. The main capabilities of the created artificial neural network for identifying PCB under test defects are analyzed. The results of the conducted neural network testing that confirm its operability and possibility of use for PCB inspection at the stage of production are presented. The software program was developed that is used for transformations over images, such as converting an image to a grayscale color space and image binarization, which speeds up the neural network by reducing the size of the input matrix to a binary value per pixel of the image. The accuracy of finding each of the PCB defects types was also investigated.Публікація Automatic Machine of Plastic Bottles and Aluminum Cans Collection for Recycling(Journal of Universal Science Research, 2023) Zharikova, I.; Nevliudov, I.; Maksymova, S.; Chala, O.Reduce, reuse, recycle is one of the key directions in the development of science and technology at this time. However, it is not enough to create opportunities for reusing PET containers. It is necessary to create mechanisms that will motivate people to collect and hand over such containers. In this article, we propose the creation of a reverse vending machine, which will issue a monetary reward to a person for handing over PET containers.Публікація Automation of Mathematical Modeling of Physical and Technological Processes in the Electronic Devices Manufacture(2021) Nevliudov, I.; Chala, O.; Botsman, I.; Klymenko, O.; Vzhesnievskyi, M.The variant of automation of the mathematical modeling process for forecasting the technological process parameters of manufacturing nano and microelectromechanical systems is proposed in the paper. For this task realization, a number of defects were identified and the causes of their occurrence were analyzed, as well as physical and technological transformations that occur in the substrates during technological processes. The software for automation of technological parameters forecasting process is developed and described.Публікація Command recognition system research(2024) Basiuk, V.; Maksymova, S.; Chala, O.This article presents experimental studies of a previously developed command recognition system. The details of the proposed mobile robot are described in detail. The setup of two experiments is presented, as well as an analysis of the results obtained. The conclusions provide recommendations for improving the accuracy of command recognition.Публікація Impact of technological operations parameters on moems components formation(2019) Filipenko, O.; Chala, O.; Bortnikova, V.; Sychova, O.; Botsman, I.In the paper the modeling results for the process of MOEMS functional surfaces shaping are presented. The significance and magnitude of factors that directly affect the shaping process of MOEMS functional surfaces were determined.Публікація Lighting Control Module Development(Journal of Universal Science Research, 2023) Vizir, Y.; Chala, O.; Maksymova, S.; Ahmad AlkhalailehLighting control is an extremely pressing task in the modern world. On the one hand, poor lighting leads to reduced safety, including injuries and deaths. On the other hand, excessive lighting leads to excess energy waste, which should be avoided. This article describes the development of a lighting control module based on Arduino Mega. The article provides a selection of the necessary equipment, and a block diagram of the proposed device is also created. A 3D model of the device case was developed, and the case was also printed on a 3D printer. The assembly of the developed lighting control module is proposed.Публікація Lighting Control Module Software Development(Journal of Universal Science Research, 2024) Vizir, Y.; Chala, O.; Maksymova, S.; Ahmad AlkhalailehThis article describes the development software for a lighting control module based on Arduino Mega. At first main requirements for such software development are considered. These requirements include the following : lighting monitoring ; determination of the normative level of illumination ; deviation warning ; lighting control. A client-server model was used. The client part is implemented in the form of a web interface, and the server part provides data storage and processing.Публікація Mathematical model of the development of manufacturing defects in the surface layer of substerates of moems’ functional components(2020) Nevliudov, I.; Omarov, M.; Chala, O.A mathematical model of the development of manufacturing defects, with the prediction of the random component of the model in the substrates of functional components of MOEMS, which are made of semiconductors, in particular, silicon, are developed in the article. The main manufacturing defects that arise in the surface layer of the substrates of the MOEMS functional components taking into account the technological processes of their production and dynamic processes were used when developing the model. The developed mathematical model takes into account the occurrence of a random component of the model with its predictive ability. The possibility of such control is the basis for the development of the scientific direction of technology and equipment for the production of semiconductors, materials and electronic devices - defect engineering, based on the management and forecasting of defect formation processes.Публікація Signals Collisions Detection In Wireless Networks(Journal of Universal Science Research, 2023) Buts, D.; Chala, O.; Maksymova, S.Within the framework of the concept of Industry and 4.0, including IoT, the use of various sensors is increasingly widespread. It is necessary to understand that it is almost impossible to avoid so-called collisions (that is, overlaps) of signals. Such overlaps can and do lead to errors that can be quite significant. This article discusses the solution to the problem of identifying collisions, and also proposes an algorithm for avoiding such overlaps. The consequence of using this algorithm is to increase the noise immunity of the wireless network.Публікація Technological process modes determination for surface formation of substrates for functional components of microoptoelectromechanical systems(Functional Materials, 2021) Nevliudov, I.; Chala, O.; Botsman, I.A method of technological modes determining for the process of substrates surfaces shaping for the functional components of microoptoelectromechanical systems is proposed, which allows to improve the quality of the substrates.
