2D thermocapillary motion of three fluids in a flat channel
Two-dimensional creeping motion of three immiscible, incompressible viscous fluids in a flat channel bounded by fixed solid walls, on which the temperature distribution is known, is investigated. The motion is induced only by the thermalcapillary forces beginning from the state of rest. Unsteady...

Frustrated Heisenberg antiferromagnets on cubic lattices: magnetic structures, exchange gaps, and non-conventional critical behaviour
We have studiedthe Heisenbergantiferromagnets characterizedby the magnetic structures with theperiods being two times larger than the lattice period. We have considered all the types of the Bravais lattices (simple cubic, bcc and fcc) and divided all these antiferromagnets into 7 classes i.e. 3...

State-feedback control principles for inverted pendulum with hysteresis in suspension
In this paper we consider the mathematical model of the inverted pendulum with the hysteretic nonlinearity (in the form of a backlash) under state feedback control. The analytic results for the stability criteria as well as for the solution of the linearized equation are observed and analyzed. The...
