Necessary time-optimality conditions in the case of two control parameters with different functional natures

A new procedure is proposed for solving optimal problems. Necessary optimality criteria are obtained for a nonlinear time-optimal problem in the presence of several control parameters of different functional structure.Translated from Matematicheskie Zametki, Vol. 7, No. 3, pp. 273–280, March, 1970.     

Calculation of the impurity distribution for diffusion in a solid crystal with inhomogeneous layers

A solution is obtained for the diffusion from a constant source at a surface in a solid crystal with an inhomogeneity in the form of a layer with high diffusion coefficient of arbitrary thickness. The expressions obtained may be used, depending on the choice of the inhomogeneous layer thickness, to investigate surface diffusion or diffusion at grain boundaries or dislocations.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 10, pp. 104–108, October, 1977.     

The experimental observation of T-layers in a moving plasma interacting with the magnetic field

This paper presents the experimental results of a study of the interaction of plasma bunches injected from an independent source into a parallel plate rail-tube (Hereafter referred to as a railtron) with the magnetic field decelerating their motion. A process of the formation of the stratified plasma structure regular in character has been detected.     

Electron phase transition in TiNi?

The optical and X-ray photoelectronic spectra and temperature dependence of magnetic susceptibility are investigated. It is found that at martensitic transformation in TiNi electron redistribution occurs which is accompanied by cardinal change of Fermi surface. Based on the data obtained in B2-structure (CsCl) E_F is assumed to lie in the kT-vicinity of the N(E) peak that determines the tendency to the structural instability of B2.
