    Does a Diocotron Effect Exist in Magnetrons?
    (2022) Moshchenko, I. O.; Nikitenko, O. M.
    In this article magnetron model has been developed for explanation why the electron beam had wavelike form before oscilation stage. As well known in crossed-field devices electrons move by cycloid-like trajectories. In accordance with the diocotron effect electron beam form has wavelike form because interaction between RF wave and electron beam. But at preoscillation stage we had the same electron beam form in magnetron both planar and cylindrical. Such form we explained by space periodical distribution of an electrostatic potential distribution.

    Value stream map optimization model in the field of educational services
    (2023) Moshchenko, I. O.; Nikitenko, O. M.
    The relevance of the implementation the Lean Production quality management model in higher educa tion institutions (HEIs) in Ukraine has been proven to optimize the stream of HEIs business processes in order to improve the quality of functioning of HEI as an economic activity subject and increase the compete tiveness of educational services, scientific and educational products. The modern approaches of scientists to the Lean Higher Education and the construction of a process model of activity and the identification of key business processes of HEIs are analyzed. The purpose of the article is to develop the optimization model for the stream of business processes based on Lean technologies and to apply the model to visualize and optimize the key process of business process at the Kharkiv National University of Radio Electronics (NURE). A DFD model of the optimization process of the Value Stream Map (VMS) - a quality management tool created within the framework of the Lean methodology for process stream analysis - was developed. The model optimization criteria are proposed. During the development of the map optimization model, the peculiarities of the result of the HEI activity, which is a combination of educational service, educational and scientific product, were taken into account. The practical significance of the article lies in the study of the HEI key process "Development of educational and methodological support of the educational process". Decomposition of the main process was carried out. The second and third levels processes for the value stream mapping was distinguished. The current state VSM of the process "Development of educational and methodological support of the educational process" was developed, the indicators of the effectiveness of the value stream at the department of information and measurement technologies of the NURE were calculated, the "bottlenecks" of the stream were analyzed. Measures to optimize "bottlenecks" based on the criterion of minimizing time are proposed. Prospects for further research in the chosen direction are determined as the implementation of Lean technologies in the activities of HEIs are the development and optimization of VSM for all key processes of HEIs.
