  • Energy conservation during treatment of sewage from populated area

    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.

  • Finite element analysis of the applicability of the applied theories of calculation of piezoelectric device of energy storage of stack configuration

    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.

    Keywords: energy storage, PEG, piezoceramics, effective mass, resonant frequency, FEM

  • Way of coding of the information at the task of the geometrical Models of executive mechanisms of robots

    The method of coding of the geometrical information is offered at the task of executive mechanisms on the basis of use of the set set of spatial primitive things and their orientation in mobile systems of co-ordinates. The method of a designation of geometrical models of mechanisms of robots is offered. One of advantages of the developed method of representation of geometrical models of kinematic chains, possibility of more exact task of a spatial configuration of manipulators by means of use of a considerable quantity of central points and various position of volume primitive things concerning a constructive plane is.

  • Management of production systems under conditions of uncertainty: a regional perspective

    The uncertainty is investigated and regularities of their impact on production systems, taking into account the search management strategies. It is proved, that uncertainty is a parameter that accompanies any productive activity for the period of the projection; due to a number of laws (integrativnost′û, integrity, communication, hierarchical structure, osuŝestvlâemost′û, etc.); is based on two basic scenarios: conservative and innovation Are key factors of uncertainty. (information, bureaucratic, change the value of the currency, sanctions, stagnation and so on) in the development of targeted corrective measures on projected periods.

    Keywords: Uncertainty and their patterns, parameters, key factors of production systems management, corrective actions

  • Acoustic method monitoring electrochemical processes

    The article describes the research of thermodurability of glass-carbon - one of the most promising carbon materials used in the production of luminophors and semiconductor materials, optical single crystals, etc. The aim of this work was to study the behavior glass-carbon in the course of thermo-cyclic testing. As a method of diagnostics of the birth and development of micro-cracks was used by the reception of signals of acoustic emission. It is shown that at heating in the samples glass-carbon there was a strong movement of dislocations in thermocyclic effects ,recognized in the signals of acoustic emission. As the number of pulses when heated above, than during the cooling of the sample, it is evidence of the accumulation of damages in the structure of the cyclic thermal processing glass-carbon samples. It is established, that the curves of the accumulation of defects at the pulses of acoustic emission, differ on the stage of heating and cooling. Proposed to use the curve of the aggregate accounts of acoustic emission pulses as a possible harbinger of destruction when heated glass-carbon of the product.

    Keywords: acoustic emission, electrodeposition, the activity of the AE, the remote control.

  • Some characteristics of migration processes in Russia and the Republic of Karelia

    The characteristics of the migration processes in Russia and the Republic of Karelia. Shown that research in the field of promotion of the Russian language and Russian as a foreign language as a native language in Russia and abroad have seen in close conjunction with the analysis of migration processes associated with the need for teaching Russian adapting foreign citizens in the country. The analysis showed that the transition to a "quiet" conditions of a market economy after the 2000 cross-country movement of labor with Russia intensified: the capacity of the Russian labor market and the increased mobility of Russians led the growth of migration flows, Russia as a whole remains a "host" side - the number of labor migrants in Russia considerably exceeds the number of Russians traveling to work abroad. Such a situation is typical for the Republic of Karelia. A comparison of labor migration on vocational qualification groups
