In this work algorithm for extracting invariant features of profile face image are proposed. In order to determine identified invariant features of profile face image, new approaches, with the help of which it can be formulated the spaces of invariant features, were suggested. © 2010 IEEE.

The emf Uoc of hot charge carriers generated in an asymmetrical p-n junction in a microwave electromagnetic field is determined by hot holes despite the fact that the temperature of electrons is much higher than that of holes. It is established that the open-circuit voltage depends on the temperature of the carriers, which determine the total current through p-n junction. © 2011 Pleiades Publishing, Ltd.

We developed the method of calculation of the temperature dependence of the magnetic susceptibility. We considered the de Haas-van Alphen (dHvA) effect in semiconductors at high temperatures and low magnetic fields. The effect of temperature on dHvA effect is explained with respect to the temperature dependence of the thermodynamic density of states in a magnetic field. © 2016 World Scientific Publishing Company.

For a parabolic-hyperbolic equation, we study the three-dimensional analog of the Tricomi problem with a noncharacteritic plane on which the type of the equation changes. The uniqueness of the solution to the problem is proved by the method of a priori estimates, and the existence of a solution is reduced to the existence of a solution to a Volterra integral equation of the second kind. © 2012 Pleiades Publishing, Ltd.
