ItemCalibration of measuring channels of non-dismantling cyber-physical systems(Lviv Politechnic Publishing House, 2021) Stadnyk Bohdan; Yatsuk Vasyl; Mykyichuk Mykola; Yatsyshyn Svyatoslav; Fröhlich Tomas; Mastylo RostyslavThe analysis of the concept of Open-Science Space is carried out. The existence of ways to achieve reproducibility and traceability of research results performed by a group of worldwide situated Cyber-physical system operators/supervisors is shown. Ways to ensure the efficient operation of Cyber-physical systems as complex technological non demountable objects with high requirements for metrological characteristics have been studied. To develop the scattered cyber physical systems, the portable stable-in-time code-controlled measures of physical quantities have been studied. They have to be metrologically confirmed in the laboratory before the delivery to the site of the measuring subsystem for its calibration. ItemModeling a network of unmanned aerial vehicles(Lviv Politechnic Publishing House, 2021) Mykyichuk Mykola; Zihanshyn NataliyaThe research concerns the methods of UAV group control in networks with duplex communication between nodes built on the “client-server” architecture. Such systems belong to self-organized networks with variable topology. It is important to study the allowable parameters of deviation from the task in the management of a group of UAVs and analysis of the network topology for the group flighting. The network was optimized according to the Ant Colony algorithm ACO. The application of different types of algorithms prevents routing problems in networks, such as ANTMANET, AntNet, ACODV and others. Methods of coordination of group joint actions are considered. A method is proposed by which the optimal number of UAVs operated by one operator can be determined and the traffic intensity of the communication channel is calculated, as well as the bandwidth and packet transmission delay are estimated. ItemThe measuring channels calibration in the industry(Lviv Politechnic Publishing House, 2021) Sulyma Oleg; Mykyichuk Mykola; Zinchuk IrynaThe trend of development of measuring equipment in particular measuring systems and technological processes leads to the need of measuring the temperature without dismantling the primary transducers and stopping the technological process in a very wide range and with high accuracy. The choice of methods and means of measurement depends on such factors as the value of measured temperature, necessary accuracy of measurement, conditions of measurements, and operation of the investigated object. The topicality of the problem is that industrial metrology operates the temperature measuring systems, transducers of which are deployed in such a way that their dismantling is impossible due to the specifics of the process or dangerous for operators’ life (nuclear power plants). Such measuring systems, due to the specifics of their application, are not metrologically provided in the periods between major repairs of controlled objects, thus violating the unity of measurements.
