Abstract: - Parametric control of the processes in continua is of interest both for the development of the theory, as well as for the practical applications in diverse technical and technological processes and systems. For example, parametric excitation of oscillations at the interfaces in continua may intensify various technological and technical processes (heat and mass transfer, mixing of different liquid components, decreasing viscosity and conductivity of media, improving a quality for crystallizating metal and many others). Then, the excitation of parameters’ oscillations is used for disintegration of the jet and film flows in the processes like spray-coating, metal spraying, granulation of materials, and so on. The opposite task is a suppression of the oscillations in a problem of stabilization of the unstable boundaries, or regimes and processes. What is more, parametric control in a number of highly effective intensive thermal, electromechanical and electrochemical processes makes possible to run even the unstable modes, which are impossible to have without proper control.

Plenary Speaker's brief Biography: Ivan Kazachkov is a Mechanical Engineer who had earned his PhD (Candidate of Physical and Mathematical Sciences, 1981) and MSc (1976) from the Kyiv National Taras Shevchenko University and got his Full Doctorship (1991) in Engineering Sciences from the Institute of Physics of the Latvian Academy of Sciences in Riga. Recently during 5 years he was teaching and doing research at the National Technical Univeristy of Ukraine “KPI”. He is also an affiliated professor at the Royal Institute of Technology in Stockholm, where he has been teaching numerical methods and doing research in modeling of multiphase systems as visiting professor (1999-2004 permanently and afterwards part-time). Since 2009 he is Head of Department of Applied Mathematics and Informatics at the Nizhyn State University named after M. Gogol. The research activities of prof. Kazachkov include Parametric Control in Continua, Multiphase Flows, Controlled Film Flow Decay, and Granulation of Metals for Special Metallurgy, Modeling and Simulation. He has over 200 publications in scientific journals and conferences, participates in European research programs and committees. A number of PhD students are doing research under his supervision.
