Abstract: We study the problem of operation of sheet rolling mills under the conditions of nonstationary technology, the stochasticity of the parameters in the presence of negative self-oscillation vibration processes associated with the “chatter” phenomenon. We… read more here.

DOI: 10.1007/s11144-019-01718-2
Abstract: The oscillatory behavior during CO oxidation over Cu foil has been observed in the temperature range of 350–750 °C. The oscillatory behavior occurred in CO excess similar to the well-known oscillations during CO oxidation over Ni… read more here.

DOI: 10.1063/1.5020130
Abstract: Two-dimensional shear flows continuously forced in the presence of dissipative effects are studied by means of numerical simulations. In contrast with most previous studies, the forcing is confined in a finite region, so the behavior… read more here.

DOI: 10.1063/10.0036115
Abstract: Self-oscillations of temperature and component concentration are one of the types of instabilities that occur in methane at low temperatures during nuclear irradiation. In this paper, we study the effect on the self-oscillations of a… read more here.

DOI: 10.1109/tac.2020.3030893
Abstract: We study a relay feedback system (RFS) having an ideal relay element and a linear, time-invariant, second-order plant. The relay element is modeled as an ideal on–off switch. And the plant is modeled using a transfer… read more here.
