Time Division Multiplexing is the one of the main information transmission technology. Main problem of this method is the large amount of empty of traffic. This number can reach about 97%. In article presents a method for reducing amount of empty traffic by using the new system pointers, that encode information about the frame . Pointer consists of three components : a pointer to a smaller source (points to the source that gave less information ), a pointer to a smaller amount of information and a pointer to the source memory block (points to the memory block , where the frame was formed ). This pointer is generated when creating a frame and is written in the first data slot. After transmitting a frame pointer is decoded, and based on this information, the distribution of data occurs on the output signals. The developed method has several advantages over similar methods of data transmission, does not depend of the speed of data sources, and have minimum depends on amount of input signals. This technology allows to fill information cells only useful information, and improve the efficiency of code up 96.6 %.

Nonstoichiometric tungsten oxides WO3–x and oxide alkaline tungsten bronzes have been studied because of their potential applications in electrochromic devices such as solar panel arrays and “smart windows”. Different phases of 
WO3–x have been considered. In this part we present results of our research which clearly show that all Magneli phases of tungsten oxides  WOx (namely W40O118, W20O58, W5O14, W18O49, W8O23, W3O8) and oxide tungsten bronzes MxMyWO3 at M-Li, Na, K, Rb, Cs. They are characterized by metal – like properties. Their band structures display an energy gap in the valence band just below the Fermi level.
We present results of our electrochemical synthesis of tungsten oxide bronzes in ionic melts of the polytungsten salts. Among the new state – of – the art methods for their manufacture, electrochemical synthesis in ionic melts, which  makes considerably better use of existing technologies, is highly productive, based on the discharge of oxyanions of the polytungstates.

The aim of this work was to conduct monitoring and make a regression model of the microbiological air pollution in Volgograd near highways. The work carried out monitoring of microbial air pollution in the residential district of Volgograd near two major highways - first and second longitudinal lines. On the first phase of research the microbial monitoring of air pollution in the residential district of Volgograd was conducted, depending on the proximity to the highway. Number of microbial cells (MC) was evaluated by sedimentation. The assumption is made about the nature of the regression relationship between microbial air pollution and the distance from the highway. Approximating functions and regression coefficients are constructed for the first portion of the longitudinal line at different levels of traffic road. Function is obtained, which allows to calculate the value of microbial contamination of the air, depending on the distance to the road and number of vehicles. In the case of high levels of the microbiological monitoring of the basin air it’s necessary to carry out measures to reduce microbial contamination of the air, for example, regular watering roads, tree planting, vegetative barriers adsorbing pollutants, chemical treatment of disinfectants. The calculation of microbial contamination of the air near a residential building located at a distance of 10 meters from the highway in the central region of Volgograd is conducted using proposed in function prediction of microbial contamination. The developed technique allows us to make calculations without setting up experiments in a specialized microbiology laboratory.

The substantiation of the need for the preparation of thermal hydraulic drive road construction machinery (SDM) operating in the North. Given that a significant number of failures falls on hydraulic drive elements, it becomes urgent need to study their work and causes of failures. In order to analyze the thermal training funds, the development of new systems is necessary to study thermal characteristics of hydraulic drive elements SDM operated at low subzero temperatures. It is necessary to take into account the rate of change of the processes occurring in the hydraulic drive. In accordance with the above requires a quality measuring equipment, created on the basis of analog-to-digital converters. For this analysis instrumentation for experimental studies. Currently, at the Department of Transportation and technological systems developed hardware and software for temperature measurement system for monitoring hydraulic drive elements SDM.

A stability problem of milling process is under consideration. A novel analytical tool is presented to assess the optimal cutting parameters which provide a chatter free machining. Chatter instability is broadly studied in the literature. However, the problem of simultaneous optimization of radial and axial depths of cut is kept out of scope. To describe the optimization method a single-degree-of-freedom model of milling process is investigated as well as corresponding equation of motion and function of cutting force. A unified delay-differential equation is proposed. A theorem of asymptotic stability is suggested. Suggested optimization technique allows to create a diagram of radial and axial depth-of-cut dependence.  As shown, there exists an extremum of function of axial and radial depth-of-cut dependence.

The article explores the main types of organization of the corporation and management in Russia. The corporation is defined as a special organizational and economic form of business. There we identified problems, specific, prospects for the formation and development. It was investigated the features and structure of corporations , as a result of its membership of the integration processes . It was measured the economic and financial management aspects, which may be useful in the development and investment attractiveness of the corporation. The Corporation is a more complex business structure. Corporations  have certain rights, privileges, and liabilities beyond those of an individual. Doing business as a corporation may yield tax or financial benefits, but these can be offset by other considerations, such as increased licensing fees or decreased personal control. Corporations may be formed for profit or nonprofit purposes. The author gives the aspects of each formation.
