In article reviewed advanced theoretical probability models of process quality formation quality of the surface layer in a centrifugal rotary process (CSO) details. Process CSO reviewed from the point of view reliability. Based on the results of theoretical studies were proposed the dependence of the influence of the main technological parameters centrifugal rotary finishing and strengthening treatment on the roughness of the processed surface, the depth of the hardened layer and the degree of hardening. Analysis of the technology processes CSO let to identify the factors exerting a dominant influence on the productivity and quality of processing. Conducted calculations of the influence the tolerances of the main quality parameters of the surface layer and technology modes centrifugal rotary processing of centrifugal rotary treatment on the magnitude of the coefficients offset instantaneous dispersion and stock accuracy which characterize the reliability of technological processes centrifugal rotary process. By results of calculations were constructed charts. Taking the presented methodology you can choose such a combination in choosing technological processes centrifugal rotary processing what will ensure the required quality of the workpiece.

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.

This paper considers basic element of device of energy storage which is a piezoelectric generator (PEG) of cylindrical form with the attached inertial mass. A finite element modeling of the device operation is carried out during active load in the external circuit. The main purpose of the operation is to compare the output potential and frequency characteristics of the device known in the literature models of systems with concentrated parameters. On the basis of these models, we can receive the analytical dependence of parameters of PEG with its geometric characteristics and mechanical properties of the used materials. However, the question of the range of applicability of these formulas is still open. In this paper, based on the numerical analysis of finite element models of PEG in package ANSYS, we obtained comparison with the analytical formulas that show the values of some parameters of simplified models and set the boundaries of their applicability.
