The article is devoted to a brief presentation style features Constructivism in the city of Rostov-on-Don. The construction boom in the city begins with the 1920s, a new style of Constructivism, had already fully declared itself in the capital. In the early 1930's. architectural development in Rostov took the path of development of the principles of the avant-garde. The very principles and forms of avant-garde come to the Rostov practice with some delay - as a kind of well-established tradition, continuity of development projects in Rostov architects

Keywords: city​​, style, shape, avantgarde facade

"Examines the relationship of the concepts on the example of post-war reconstruction of post-war reconstruction of the city of Rostov-on-Don.
In 1945, the Chairman of the Committee on Architecture AG Mordvinov announced seven conditions under which you can create the city.
In 1945, the development of the urban plan of rebuilding the city of Rostov-on-Don was appointed academician of architecture VN Semenov.
In 1949. master plan was finalized at the construction site.
In general, the basic idea of the architect was executed. Among the fifteen cities prone to restore the city of Rostov was restored in all seven conditions put forward by the Chairman and the Committee for Architecture AG Mordvinov, projected architecture academician VN Semenov and given a reality by means of the chief architect of YA Rehbein."  

Keywords: master plan, concept, post-war reconstruction, the condition of the city

To study complex sonar systems, the method of decomposition was suggested. The peculiarities of the method applied to the sonar systems were considered. A four-level hierarchy of decomposition subsystems is proposed. A scheme of the first level of semantic decomposition was presented. Controlled modules allowed to build adaptive systems were described.

Keywords: decomposition, hydro speaker systems, hierarchy of subsystems

The article briefly describes the history пояявления hydrophobic cements. Considered one of the прспективных directions for the use of water-repellent additives today - in the dry construction mixtures and confirmed the significance of this direction. The article describes the results of experiments on the impact on the indicators of a cement-sandy solution additives series GMI and the analysis of the received data  

Keywords: hydrophobic cement, hydrophobic additives, dry construction mixtures, porosity of a cement stone, strength cement-sandy solution, involving air, antifoam, antifoam agent

Influence of the fluorinated surface-active substances entered info a solution of chemical nickel plating, on operational properties nickel-phosphoric of the coverings besieged from investigated structures (solutions) is considered.

Keywords: nickel-phosphoric of the covering; surface-active substances; operational properties

The method of estimating of generator frequencies for radio-electronic devices based on coupling treatment of formed signal phases is considered. The correlations setting the correspondence of potentially achieved accuracy of frequency estimations for each generator to their number and parameter values are presented.

Keywords: generator, frequency estimation, function of maximum likelihood estimation, estimation of dispersion

We have carried out the analysis on the scientific and technological literature on methods of calculation and analysis of the x-ray diffraction, x-ray absorption and Raman spectra used to analyse the structure of the materials for hydrogen storage under realistic operating conditions. The simulations were carried out for the series of small palladium nanoclusters with embedded hydrogen. Multiscale computer modelling was used to simulate the dynamics of structure of the materials during charge/discharge phases.

Keywords: hydrogen storage, XANES, x-ray diffraction, Raman scattering, fuel cell

The article is devoted to modeling the collision of the plant parts with stable surface. The process of collision objects with complex geometry is not fully understood. Mathematical model of dry stalks of cereal plants as an object of a polygonal cylinder shape is studied.

The article is devoted to the mathematical modeling of the plant`s development. The graph theory is used to model the plant objects with different types of branching and its growth.

Keywords: model, the plant object, stem, directed graph

  The paper offers a solution to the general problem of circuit synthesis for n-MOS transistor level band pass filter based on current amplifier with a limited transmission coefficient. The possibility of optimal choice of the parametric compromise. The results of modeling circuit in Cadence Virtuoso environment component-based workflow SGB25VD.

Post-war reconstruction of the city of Rostov-on-Don to be divided in to two stages from 14 February 1943. to 1946 and from 1946 to 1956., restore to different choices and features of design and construction. Up to 1946. rehabilitation works are mainly ofthe nature of small repairs of small houses and decoration of apartments. To restor elarge objects started at the end of 1946. A commission was established to restore,which was engaged in the survey of destroyed buildings and made decision sab out the method of recovery. Methods: repair, reconstruction with elements of restoration and reconstruction. Among design organizations involved in the restoration of Rostov special place"Gorproekt."

A theoretical study of the mechanism of mixed (semifluid) the interaction of the solid lubricant lubricants shell rods with contact "wheel-rail." Methods for determination of the average standard resource shell lubricating grease solid rods and medium wear hard shell shell lubricants rods in various combinations shells at different ranges of temperatures. A fundamentally new way of tribology hard shell lubricants rods "shell holder - movie." Determined on the basis of laboratory tests the new composition of lubricating rods having good lubricity and increased resource consumption less lubrication at elevated temperatures of contact compared to a typical sample of lubricating rods.
