Abstract
A method for the frame compensation of camera motion using a photoplan is proposed. The method is based on replacing the aerospace image of photoplan fragment and will thereby increase the compression rate. This method is used for compressing aerospace images in cyclic video monitoring systems terrestrial objects using aircraft.

Abstract
The article analyses a new approach of optimal routing of information flows in telecommunication networks using of QoS parameters. The state of art of QoS is presented. The general principals of optimal routing are formulated. The average packet delay in the network is analyzed more detail. In conclusion general problem for investigation has been formulated as problem based on Service-Oriented Architecture.

Abstract
Composition materials on the base of Pb0,75Ba0,15Zr0,53Ti0,47O3 (PBZT) with micro-inclusions of Cu and Ni are prepared by a complex ceramic technology. This technology includes metallization procedures by means of the chemical deposition method from standard solutions of nickel and copper. At determination of correlation of the structure of PBZT composites and their dielectric properties it was shown that dielectric losses increase with decreasing temperature. This is caused by the domination of the real part of the complex dielectric permittivity.

Abstract
A mathematical model of communications channel that transfers data by means of separate photons having different polarization has been developed. The expression for calculating of optic fiber throughput has been obtained that takes into account probabilities of depolarization and absorption of radiation photon. As a result of implemented simulation it has been found that data throughput depends on the length of optic fiber. It has been established that photon absorption as compared with its depolarization contributes greatly to the size of optic fiber throughput.

Abstract
General approach to the development of software designed for visualization of the spectra obtained by laser express examination is described. Requirements for the creation of specialized software are presented. A model of programmatic spectrum visualizer and model for a generalized data library of spectral lines were designed with use of structural methodologies. The general architecture of the client application that is associated with the visualization of registered spectra was described. Software allows to obtain fast and accurate examination, collect the required results in a database for further processing, and visualize and scale the spectra obtained.

Abstract
The experimental complex of apparatus of electrical stimulation with combination of active electrode vibration of original design is developed. It has a possibility to use various mechanical and electrical parameters of vibration influence and electrical stimulation. It’s possibile to apply various directions of vibrations to an active electrical stimulation electrode. It’s shown that use of vibration-combined electrical stimulation procedure has an advantage in efficiency over traditional non-vibrating regime of procedure. Moreover, percussive-frictional mode is superior due to opportunities it has to change the modes of action.

Abstract
The algorithms to suppress oscillations that occur during the movement of payload by hoisting-and-transport mechanism are presented. The use of fuzzy logic provides quite simple to implement a control unit and take into account actual constraints of drives. Anti-sway control based on fuzzy logic has a good performance, even in the case of changing length of the payload cable in a wide range, as it’s shown by simulation.

Abstract
The problem of bit allocation in the context of the tree structure 2D paraunitary filter bank based on the quaternion algebra, i.e. 4-band packet wavelet transform, is considered. It was shown that the bit allocation is optimal if the quantizers error variances in the encoder channels are equaled.

Abstract
The traditional excitation equations are based at the representation of excitating by extraneous sources field in form the sum of own waves TE ( H ) and TM ( E ) of the hollow waveguide, which transverses components form the complete basis in class of transverses vectors of section this waveguide. However in the sources area (longitudinal sonde, electron beam) the waveguide is not hollow and in this area exist potential transverse electric field. The transverse electric field expand the bases of E and H waves. This is not taken into account in the traditional excitation equations. In this paper the necessary correction of the excitation equations in sources area is performed.

Abstract
The measurements results of the electromagnetic properties of schungite-based finishing agents are given. The schungite-based finishing agents could be used for shielding of electromagnetic radiation from electronic facilities to provide electromagnetic protection in the residential areas and to create protection from electromagnetic emanation from medical equipment. The electromagnetic radiation transfer coefficient provided by the samples of finishing agents is in the range from -10 to -30 dB in the frequency range 0,5-18 GHz.
