Recently becoming urgent problem of managing distributed processes of production, transmission and consumption of energy. This fact is associated with the emergence of a significant number of generators and the possibility of a primary control on all elements of the grid. In this connection, in proposed three-level distributed power grid management, which includes the upper level of segmentation networks, distributed control average frequency and power level and a lower primary control. The methods of control for each of the above levels, the results of simulation.

In the present study, platinum was electrodeposited onto rotating disc electrode coated with Vulcan XC-72R Nafion suspension and uncoated smooth glassy carbon electrode from acidic solution of 5mМ H2PtCl6. The electrochemically active surface area of platinum particles obtained was determined by cyclic voltammetry and the structural characteristic of the particles was studied by scanning electron microscopy. The impact of current and time on the electrochemically active surface area of platinum particles electrodeposited on the carbon supports was also investigated and described in this paper. The present work is expected to be utilized and contribute to the improvement of electrochemically active surface area of platinum catalysts for low temperature fuel cells.

Background. Methods vibrodiagnostics allow to identify the emergence and development of de-fects at an early stage. Of particular relevance is the use of vibrodiagnostic methods for condition monitoring mechanisms under the simultaneous influence many unpredictable factors, varying operating conditions. The vibration causes blurring the boundaries of the focused image, allow-ing you to build a simple compact optical vibration sensor. (Materials and / or methods). Vibro-diagnostics used method for detecting focused optical im-age nodes being monitored. Determination of vibration parameters produced by wavelet analysis of the luminance distribution boundaries of the focused image. (Results). It is shown that the periodic movement of give in the image boundaries bends function (maxima of the second derivative). Character kinks function determined by the change speed of the change of the image boundaries. Continuous wavelet transform of the luminance distribution on the border of the image at a certain level amplitude vibrations cause the appearance of two maxima curves continuous wavelet transform, the amount of which is reduced proportionally. (Conclusion). Theoretical and experimental studies have shown that the optical image registra-tion allows you to register with the sensitivity of the vibration amplitude of 0.1 - 0.15 pixel ma-trix photo detector. For a pixel size of about 5 microns, a linear increase in the order of the opti-cal system 20 sensitivity in amplitude of vibration may reach values of 0.02 microns, which cor-responds to the sensitivity is achieved by holographic interferometry.

Symmetry of single-walled carbon nanotubes is analyzed using the parent phase approach. Transfer of the planar hexagonal order of graphene sheet onto surfaces of chiral and achiral nanotubes is divided into two steps. At the first step the rotational symmetry of graphene is reduced. In addition, the reflection symmetry is vanished for chiral nanotubes. At the second step the resulting subgroup symmetry is mapped in homomorphical way onto the symmetry group of the single-walled nanotube.

The paper presents the results of computational statistical experiment to estimate field radiation exposure on the soft tissue of the human body when external pressures are nondivergent narrow beam of gamma photon radiation. As an example, adopted the energy of a photon that enters 102 group energy axis constant laboratory ABBN. Given dose distribution in a cylinder diameter of 20 and a length of 10 centimeters. The method of statistical tests, known as Monte Carlo. Is used modify of the method with calculation the inverse functions. It is shown that the dose outside the beam ionization radiation load decreases by two orders, remains finite, that should be considered in therapeutic procedures, in which the total dose exceeds the lethal dose for a healthy bod

At present an important role in solving energy conservation problem is assigned to thermal pumping plants (TPP). Using processes of evaporation and condensation of easily boiling liquid circulating in the system they extract low potential heat from environmental objects and provide heat supply for buildings, constructions, greenhousee and so on. Artificial sources of low potential heat for TPP of different capacity can be, for instance, ventilation air and exhaust gases, circulating and waste water,ground. Energy efficient reasonability of TPP use in the system of water disposal for the town of Novocherkassk in Rostov region is considered. Calculations indicate that there is a technical potential to replace a boiler house operating on expensive gas fuel and emissing into the atmospere more than 850 t of carbon dioxide - greenhouse gas - with ecologically clean TPP, one of which uses heat of waste water and the other - heat of ground.
