(University of Naples "Federico II", 2020) Stashkevych, I. I. ; Turlakova, S. S.; Shevchenko, O.; Derzhevetska, M.; Турлакова, С. С.
The structural and functional IDEF0-model of information support of processes of minimization of resistance of the personnel to organizational changes at the enterprise is developed. The proposed model makes it possible to describe in a logical, convenient and consistent form therelationship between management functions and responsible executives, provides information about resources, information flows, instructions, regulatory information, a set of models and approaches. The corresponding model in the notation IDEF0 will provide information support for decision-makingon the management of organizational changes at the enterprise.
Study of metrological characteristics of low-cost digital temperature sensors for greenhouse conditions
(Faculty of Technical Sciences, Čačak, 2020) Vovna, O. V.; Laktionov, I. S.; Koyfman, O. O.; Stashkevych, I. I.; Lebediev, V. A.; Койфман, О. О.
The article focuses on the relevant scientific and applied problem of assessing and analyzing the metrological characteristics of available digital temperature sensors for greenhouse conditions. The hardware and software implementation of the microprocessor system for obtaining calibration characteristics and evaluating the accuracy and performance of temperature sensors for the physical media under greenhouse conditions is studied. A particular type of linear calibration equation for the temperature sensors under study is established. The values of systematic absolute measurement deviations of temperature sensors DS18B20, SHT11, SHT21, BMP180, BME280 and DHT22 are experimentally obtained. Recommendations on improving the accuracy of temperature information and temperature measuring systems under greenhouse conditions are given. The perspective areas of the research on metrological provision of modern means of automatic monitoring and temperature control in industrial greenhouses are substantiated.
