Публікація A Generalised Mathematical Model of Electricity Consumption for Electric Drives in Smart Cities Applications(2025) Shevchenko, A.; Kolupaieva, I.; Romashov, Y.The generalised mathematical model of electricity consumption is developed by using electromechanical analogies and Lagrange's equations of 2-nd kind in the view of the system of two first order and one two order ordinary differential equations with the related initial conditions. It allows representing the dependency between supplied voltage and the electricity consumption of the electric drive. This mathematical model is for following researches directed to formulate and to solve the problem of the optimal control theory, so that it allows developing the energy efficient automated controls for electric drives required in smart cities applicationsПублікація Circular Concepts of Research Robotics for Small Scale Benchmarks in Automation Engineering of Smart Cities(2025) Tkalenko, M.; Kolupaieva, I.; Romashov, Y.The standardisation of the parts and the usage of the 3D printing are considered as the concepts allowing to develop the research robotics prototypes for benchmarks of engineering automation's solutions to implement in support smart cities applications. It allows to provide the Reduce and Reuse principles of the circular economy at present, but implementations of the Recycle principle required complementary technologies not fully accessed at present. Small scales of the robotics prototypes decrease exploitational energy consumptions during the researches, so that the related carbon emissions are decreasedПублікація Digital Gap in EU Countries and its Impact on Labour Productivity and Global Competitiveness(University of Hradec Králové, 2021) Polozova, T. V.; Kolupaieva, I.; Sheiko, I.Nowadays digitalization has become a global trend that allows countries and individuals to get a number of benefits for economic and social development. Every country is trying to promote digital innovation through regulatory policies. However, the results of such policies vary for different countries, creating digitalization gaps. The aim of the research is to assess the gaps in digitalization process and productivity among EU-members countries, and to evaluate how such gap impact on competitiveness of the country. On the basis of DESI index and labour productivity data for EU-members four clusters were formed. Also, on the base of International DESI index and Global Competitiveness Score EU-members and seven global developed countries were divided into four clusters. As a result, leaders, perspective countries, followers and transition countries were identified reflecting the digital and labour productivity divide between them. Leading positions are occupied by North Europe countries, while number of Eastern Europe countries located at opposite side. Results of cluster analysis shows the linkage between digital development and human development due to co-movement of DESI and Human Development Index.Публікація Potentiometer Sensors of an Angular Acceleration for Research Robots to Benchmark Smart Cities Applications(2025) Cherkashyn, M.; Kolupaieva, I.; Romashov, Y.The estimations of angular accelerations by means of the potentiometer sensors are considered in the context of the applications in small-scale research robotics prototypes for benchmarking of automation engineering's solutions to support full-scale implementations related with smart cities. It is proved, that potentiometer sensors are possible for instrumental estimations of angular accelerations, but it requires defining the first and second derivatives on the time of the measured voltage incorrect in Adamar's sense, so that it is necessary to propose the suitable regularisation approach to have reliable estimations for angular accelerations
