The paper deals with the problem of estimation of the topological entropy for discrete-time nonlinear systems via the second (direct) Lyapunov method. The main result of the paper is illustrated by examples concerning the Hénon system and forced bouncing ball oscillator. An application to the observability problem via digital channels with limited data rate(More)
During and after space missions crew members showed significant vestibular changes. The cosmonaut-researcher of the orbital complex Soyuz T-7--Salyut-7 developed inhibition of compensatory and enhancement of nystagmic eye movements in response to active head movements in the frontal plane. During an acute stage of readaptation crew members of the orbital(More)
