    Algorithm for Selection Equipment to Reduce the Technogenic Effect on the Environment
    (Institutul de Energetica, 2022) Козій, Іван Сергійович; Козий, Иван Сергеевич; Kozii, Ivan Serhiiovych; Пляцук, Леонід Дмитрович; Пляцук, Леонид Дмитриевич; Pliatsuk, Leonid Dmytrovych; Коваль, Віталій Вікторович; Коваль, Виталий Викторович; Koval, Vitalii Viktorovych
    The work is devoted to the development of an algorithm for selection dust and gas purification equipment in order to reduce the anthropogenic impact on the environment from emissions of the heat, power and chemical industries, which are sources of complex environmental pollution. The need for the research was necessitated by the inefficiency of environmental measures taken due to the huge number of devices with different designs for emissions’ purification, their non-universality and low efficiency of the purification systems. The main goal of the study was to develop a software algorithm for the reasonable choice of the optimal dust and gas purification equipment, taking into account the actual conditions of the technological environment and the characteristics of pollutants. The goal was achieved using a logical and mathematical description of the pollutant parameters, environmental conditions and process equipment parameters. The uniqueness of the developed algorithm consisted of rechecking the compliance of each equipment parameter with environmental conditions and pollutant characteristics. The most important aims were to obtain an algorithm for selection efficient equipment, taking into account its parameters and initial characteristics of pollutants and environmental conditions, the simplicity and accessibility of its implementation for a wide number of industrial facilities in the heat, power and chemical industries. The proposed algorithm, in contrast to the approaches used in practice, was characterized by the work flexibility due to the possibility of supplementing and improving the databases of pollutants and equipment.

    Modelling of Ultrashort Electromagnetic Clusters Forming in Two-Stream Superheterodyne Free Electron Lasers
    (Sumy State University, 2015) Лисенко, Олександр Володимирович (ЕлІТ); Лысенко, Александр Владимирович (ЕлІТ); Lysenko, Oleksandr Volodymyrovych (ЕлІТ); Ромбовський, Михайло Юрійович; Ромбовский, Михаил Юрьевич; Rombovskyi, Mykhailo Yuriiovych; Коваль, Віталій Вікторович; Коваль, Виталий Викторович; Koval, Vitalii Viktorovych; Volk, I.I.
    Two-stream superheterodyne FELs are characterized by exceptionally high rates of the amplification of electromagnetic waves in the submillimeter- IR range. Such high rates of the amplification are achieved through the use of the additional amplification mechanism of SCW due to the twostream instability [1]. There is a possibility of the generation of ultrashort intense clusters of an electromagnetic field on the basis of such multiharmonic TSFEL as a result of the superposition of many harmonics. Such ultrashort electromagnetic clusters, as well as ultrashort pulses can have wide practical application for a number of fundamental and applied researches in physics, chemistry, biology and medicine.
