A canonical optimal control problem for linear systems with time-varying coefficients is considered in the class of discrete controls. On the basis of linear programming methods, two primal and two dual methods of constructing optimal open-loop controls are proposed. A method of synthesis of optimal feedback control is described. Results are illustrated by(More)
The comparative electron-microscopic study of early stages of the interaction of Y. pseudotuberculosis virulent strain (No. 282) with "professional" (macrophages) and "nonprofessional" (HeLa cells) phagocytes has been carried out. The character of the intimate mechanism of this interaction has been found to be essentially different. The common feature for(More)
The surface structure of chlamydial elementary bodies (strain PL-B577 causing enzootic abortion of ewes and strain CP-1 isolated from a patient with Reiter's syndrome), concentrated directly on the grid of an electron microscope, was studied by the method of negative staining. The surface of the cell wall of chlamydial elementary bodies in the preparations(More)

A comparative light-optical and submicroscopic study was made of the development of strains ofToxoplasma gondii with high and low virulence in macrophages in vitro. By contrast with the active multiplication of the highly virulent strain, most toxoplasmas of the less virulent strain underwent disintegration within a few hours after penetrating into the(More)
A linear uncertain system with bounded unknown initial states, disturbances and errors of a sensor is investigated. Optimal observation problems are introduced the solutions of which give estimates sufficient to construct in real-time optimal guaranteeing controls to the terminal control problem under uncertainty. The algorithms suggested are based on the(More)
The antigenic structure of the L-forms of salmonellae (S. typhimurium and S. typhi) in comparison with that of the initial bacterial cultures and revertant cultures was studied with the use of the immunoferritin method. The L-forms of salmonellae were found to retain an insignificant amount of O-antigen, as well as to have K-antigen on the surface of the(More)
