The structure of the simulation model of an territorial technological safety system (TTSS) as a service system has been proposed. Input flow simulates the possible technological accidents caused by random and systematic failures of production equipment of territorial production system. The simulation model proposed is considered as a platform for making decision concerning parameters of TTSS programs. Fig. 2. Ref.: 9 items.

Codes with summation are widely used in concurrent error detection systems of automation and computing logical devices. In this paper the problem of errors of data vectors detection for the case of faultlessness of check vectors efficiency increasing is being solved. Herewith new codes with summation detect more symmetric errors of data vectors than classic Berger codes or modulo codes with summation. Moreover, codes described in the paper keep an important feature of Berger codes – an ability to detect all the unidirectional errors of data vectors. Tab. 5. Fig. 7. Ref.: 38 items.

Justified, what is remarkable is the appearance of the video system services that provide services-three-dimensional digital display high quality build. Shows the relevance of the technology of processing the sequence of human planes, represent-related components as a single full color kad-RA, and stereocamera. This scheme is effective in the case of con-Vaernes implementation on spectraserv. Fig. 2. Ref.: 6 items.

The paper theoretically investigates the photogalvanic effect in optic transitions between spin subzones of Landau levels within an ultraquantum limit. A geometry is considered when polarization is perpendicular and the electric current is directed along the magnetic field. The effect is caused by cubic terms in the Hamiltonian function, which exist due to the absence of an inversion center. The considered magnetic field relation is of resonance character, the said relation having both odd and even field contributions. Such an effect character is related to the resonance in the intermediate state and interference of second order transition amplitudes in relativistic contributions in the Hamiltonian function. Key words: photogalvanic effect, optic transitions, magnetic field, inversion center, polarization, relativistic contributions, Hamiltonian function, resonance.

The analysis of the minimum time to transmit video information. As a result, we show that for current and future aerospace monitoring systems using on-board telecommunications video delivery time up to several tens of minutes. This leads to the obsolescence of the information obtained, and the belated adoption of wrong decisions. It is proved that for solving this problem, we propose to use video compression technology. We justify the fact that the representation of an array of the perforation upper level elements in the differential polyadic space provides an additional reduction of combinatorial redundancy. It is shown that to avoid the disadvantages associated with a decrease in the lower limit of the differential polyadic space required for perforating technology further consider the binary mask wavelet elements of the upper and lower levels. Outlines the development of differentiated image compression method for increasing the availability of video data, which is based on the following technology solutions: derivation of images fragments on a combined scheme, the organization perforation arrays in a two-dimensional representation of the differential polyadic space, mask-dimensional block coding scheme.
