Item Study of the primary converter-object system for electrochemical devices(Lviv Politechnic Publishing House, 2021) Bubela Tetiana; Yatsuk Vasyl; Fedyshyn Tetiana; Ivakh Roman; Krachunov HristoТhe problem of creating electrochemical devices and the issues that arise in the system of the primary converter object of control are considered. Low-resistance (salt solutions) and high-resistance (sugar solutions) objects were selected as the subject of study. To solve the problem, we have applied the method of impedance spectrum analysis with EIS Spectrum Analyzer software, which performs modeling on the Levenberg–Marquardt algorithm. Substitution schemes in different frequency and concentration ranges of studied objects were synthesized. This enables appropriate corrective action to minimize the impact of adverse events in the system while monitoring the quality of solutions – non-electrical nature objects – by electrochemical devices.Item Calibration 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.
