At the present stage, energy-efficient construction is one of the important issues included in the legislation in most countries. One of the promising ways of lowering thermal energy demand for heating is to reduce heat losses with air exchange in buildings, which accounts for over 60% of heat loss.
Civilizational development of the society is only possible with the decrease in specific energy consumption and economical use of heat. The article discusses the main methods to improve energy performance of buildings under construction and operation. It also addressed issues of investment in energy efficiency projects. The article substantiates the effectiveness of the combined extract and input ventilation with heat recovery of vented emissions in Rostov- on-Don.  

Keywords: energy conservation, improvement of the energy efficiency, efficiency assessment, investment, energy-saving measures.

Consensus problem involves a system of processes, some of which may be faulty. A fundamental problem of fault-tolerant distributed computing is for the reliable processes to reach a agreement on a same decision. One approach to achieving such agreement is for processes to vote and agree on the majority value. In the absence of faults, this works fine, but the vote even one faulty process can swing the outcome. In this paper we present some result of analysis of a mixed-failure model, where t processes may fail, b out of which is the Byzantine failures and remaining c is crash processes. In a asynchronous model of computation for several distributed problems it turns out that a collection of N processes can tolerate c crash failures if 2c < N, while robustness against b Byzantine failures requires 3b < N. Our algorithm rely on a weak definition of the Byzantine failures which disallows them act as a dead or a crash processes and can tolerate the 2(N – 2c)/3 failures.

The possibilities of waveguide elements realization in the structure of multilayered integrated chips of centimeter and millimeter ranges with SIW (Substrate Integrated Waveguide)-technology application are considered. The approaches allowing effectively using in new structures the algorithms and techniques of the electrodynamic analysis and synthesis of passive devices on classical all-metal waveguides are offered. Advantages of use in SIW structure the waveguides of complex cross-section are considered on the example of the microwave band-pass filter.

In this article the basic parameters required for residual life assessment and life extension of the technical condition of water or long operated facilities. Inlet water or prolonged use many facilities design elements out of order it - complete destruction of concrete structures water conveyance structures, the formation of defects, normal operational performance of the design water conveyance facilities, such as violation of butt joints, as well as the destruction of the individual elements of the structure, etc. During the development of methods for extending the life cycle of water conveyance structures are obtained by the use of impervious geotextile cover that make for a correct evaluation of residual life of structures may extend its operational life cycle. The question arises of the need for correct and timely manner and to assess the remaining amount of the carrying capacity of water conveyance structures, to evaluate the technical condition and extend its life cycle. To do this, we can apply the proposed impervious geotextile cover.

  In many applications of profiling cutting tool, define the envelope surface collection. Along with the classic approach to the definition of the envelope of the recently used and new. So, if your family schedule projected two-dimensional surfaces in space R4, then get some three dimensional hypersurface Σ. Kriminanta this is the envelope of family of surfaces. The authors study the surface Σ when setting its parametric equations and equation in implicit form held in the works.  Found some new properties of such surfaces. Due to the fact that when profiling cutting tool set family of surfaces, coordinate transformation equations, an important task is the study received thus hypersurface. On the basis of article studies obtained in a general manner the necessary payment according to calculate kriminanty and diskriminanty hypersurface.  They show examples of how to define envelopes two families of spheres. These are family formulas transform coordinates defining the translational and helical movement. The results are illustrated by computer polygonal models.
