RAISE VELOCITY OF IMPLEMENTATION OF OPERATIONA MODULAR ERECTION OF DEGREE MULTI-NUMBERS
Chervaykov N.I., Lobes M.V.
Abstract
The algorithm Montgomery of accelerated modular multiplication multi-numbers is considered in this article. Suggested adapt it for residue number system. Shown that such modification of the algorithm Montgomery gives a huge advantage in time of the operation of modular multiplication and hence a modular erection of degree.

MODELING OF REFRACTION FACTOR IN LINEARAND NONLINEAR MODES FOR NANOSTRUCTURE SITALL
Sultanov A.H., Vinogradova I.L., Salihov A.I.
Abstract
The mathematical modeling of refraction factor in linear and nonlinear modes for nanostructure sitall is carried out. The analytical method is based on model of a movement intense oscillator, exposed to action of an external light. It is shown, that the nonlinear mode of a movement is accompanied by self-influence, and also possible generation of the second and third harmonics. The error of a method is appreciated which makes 3 - 4 %. Factor nonlinear rigidity for nanostructure sitall is found. The analysis of dependences determining change of a refraction parameter from intensity of light, has shown presence three characteristic sites - detained nonlinear mode, spasmodic growth and flat almost linear growth of a refraction parameter.

THE ASIMPTOTIC ESTIMATION OF NONALGEBRAICREDUNDANT CODES DECODING PROCEDURE
Gladkikh A.A., Shakurov R.S., Ukraintsev K.J.
Abstract
There are considered various approaches to decoding error-correcting codes in light of achievement of extremely possible power prize at received code vectors restoration. There are comparative estimations for hard and soft decoding methods. There is shown the efficiency increase opportunity of binary error-correcting codes soft decoding due to replacement of Hamming metrics by procedure of consecutive approximation to the received code vector decision.

OPTICAL NETWOKS DESTRIBUTION RELIABILITY
Kornilov I.I., Marykova L.A., Shatalov V.F.
Abstract
Optical networks requirements are mainly met den to their reliability. Fabre optic ring networks are involved mostly. Net distribution typology is constructed for such nets. Ring stand-by topology lets batten reliability considerably. A valuation of reliability measurements on distributed nets demonstrate that time breaks is reduced considerably. It matters greatly for both - users and providers of the net.

ANALYSIS OF ELECTRONIC PROCUREMENT SYSTEMSAND APPLICATIONS: POSITIONING ALTERNATIVES
Medzibovskaja N.S.
Abstract
This paper is devoted to the application of inter-organizational information systems in the electronic procurement. Electronic procurement is defined as a comprehensive process in which organizations use IT systems to establish agreements for the acquisition of products or services (contracting) or purchase products or services in exchange for payment (purchasing). We develop a classification grid of industrial buying situations and then explicitly link likely El-business application to the various situations.

INVESTIGATING OF THE MODULE «RECEIVINGAND ACCOMPANYING OF AN ORDER» OF THE INTEGRATEDINFORMATION MANAGING SYSTEM FOR INDUSTRIAL ENTERPRISE ACCORDING TO RISE EFFICIENCY OF SALES MANAGEMENT
Matveeva E.A.
Abstract
On the basis of industrial enterprises analyses in this article are shown recommendations for investigating of the module «Receiving and accompanying of an order». Module is presented by two schemes: «order forming, materials storing, transference of order for manufacturing» and «accompanying of order fulfill, stocktaking of ready production sending». The schemes shown are typical and with little changes can be used for an any industrial enterprise. Correctly formed information links allow to shorten a fulfill time for the order and to rise a quality of customer service.

HEART RHYTHM DIAGRAMS STRUCTURAL-TOPOLOGICALFEATURES
Kuznetsov A.A.
Abstract
The technology of a heart rhythm diagrams (HRD) consecutive differentiation is given. The comparative parametrical analysis of the differential lines (DL) received on initial real and virtual HRD is carried out. It is shown, that each DL member of a degree i contains i information quantity about the next members of initial lines HRD. From the certain value i the DL diagrams topological structure qualitatively do not vary. The allocated communication between members of some initial HRD in the length i readout speaks presence «included» independent regulator mechanisms. Key words: the diagram of a rhythm of heart (HRD), differential number(line) (DL), topological structure, mechanisms.
