The research of algebraic cryptanalysis method was carried out in this work. Systems of the equations for tables of various sizes of nonlinear transformations of substitution for simplified model of GOST28147-89 algorithm are received, also we solve a one of this systems by a XL method. During this work we produced a program, which has realised a generation and solving of system of equations describing nonlinear transformations of substitution. We analysed a nonlinear systems of equations and calculated a value of complexity of XL method for eight blocks of substitution.

ZnO nanorod arrays have been synthesized on silicon wafers by chemical vapor deposition (CVD) technique with different temperature modes, without metal catalyst. With this method vertically aligned ZnO nanostructures were grown at the quite low temperatures. Modification of the method allowed to place silicon substrates in areas with different ratios of concentrations of the molecules in the vapor phase. Photoluminescence spectroscopy and electron microscopy studies have shown that morphologies and optical properties of nanorods depends on different ratios of concentrations of the molecules in the vapor phase.

The arrays of ZnO nanorods were obtained on the sapphire substrates by means of pulsed laser deposition under the high pressure of argon. The conditions of synthesis were optimized, and their influence on the morphology of ZnO nanostructures were revealed. It is shown that the concentration of oxygen vacancies in ZnO nanorods can be changed by regulation of the synthesis temperature from 850 to 915 °. This process can be controlled by the ratio of intensities of the photoluminescence emission in the visible and ultraviolet regions. So, it allows to create nanostructures for UV photodetectors or chemosensors depending on the temperature choice.

The method of application of fuzzy logic to solve the problem of spatial planning using geographic and information systems is described. The spatial arrangement of objects on the map is used as input factors of the solution, to find which a model of the spatial descriptions of objects using a bitmap representation is constructed. The way of formalizing fuzzy judgments about positional relationship of objects and the system of inference making based on the fuzzy logic methods is developed. An example of using the method described in this article to determine the sanitary protection zone of industrial waste landfill in the territory of the Republic of Bashkortostan is given

In this paper the technology of repair of ground water retaining structures soil mixture improved quality with and without soil mixture install.Use soil mixture , improved sharps and ensure the return of ashes (repaired ) slopes and ridge structures of high strength (up to 13-15 MPa) and water resistance , thus increasing the effectiveness and quality of the repair work and increased resistance to the elements of the structures induced defect . The presence of the bran soil mixture not only enhances the strength of 30-40% , but also gives a significant increase in water and frost (20-30 %), which prevent or substantially reduce the infiltration of water through the filtration body water retaining structures , since high strength and frost soil-concrete being laid on a slope ( in the recovery slope failure ) and groove (at soil dumping and capacity to or in excess of the design marks ) will reliably protect the body of the dams ( dams ) of the drawdown , erosion , buckling , suffusion , and other deformities.

The article describes peculiarities of modern syntax parser systems and problems originating in text analysis. As a result of comparative analysis the authors propose a unified approach to processing of unstructured texts in Russian and English which combines morphology and syntax processing. The developed syntax analysis system, using verbs’ valency dictionary, samples of minimal structural schemes of sentences and samples of conjunctions, allows choosing predicative structures of sentences in the text, realizing initial semantic analysis due to semantic content of predicate’s actants and building trees of syntactical subordination of sentences. The derived trees hold elements of tree of constitutives and tree of dependences. The proposed samples and rules organization allows resolving some of the problems of modern parsers. And the use of verbs’ valency dictionary allows reducing the number of sentences syntax analysis variants.
