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 results of the heat transfer processes studies in the heat exchange borehole (BHE), equipped with coaxial collector in order to establish the influence of its design parameters, the properties of the rock mass, mode and duration of the coolant flow to the effective temperature difference. The resulting analytical equation for the effective temperature difference in the conditions of unsteady heat transfer experimentally verified in a lab BHE and can be used in the design of these BHE systems in specific geological and technical conditions. Use the resulting equation for the inverse calculation can be counted the diameter and the depth of the BHE, as well as the duration of the coolant circulation in the coaxial collector. The advantage of such approach is the consideration of the main factors that influence the of the effective temperature difference.

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.

  Laboratory technology was developed to fabricate flexible piezocomposites with ferroelectric phase - polymers having signal reception factorv • gv 5000 • 10-15 m2 / N. The values of the given coefficient were achieved by switching from a probabilistic (spontaneous) percolation to a correlated one in the process of forming material. This made the production of 0-1–3 piezocomposites, in which a part of piezophase has 0 connectivity, and the other part – 1 connectivity possible. To improve the efficiency of piezocomposite polarization before their manufacturing the surface of piezophase particles, which were obtained by the partial destruction of the porous frameworks, was treated with coupling agent, which did not only improve the polymer adhesion to piezophase, but also allowed the removal of water from the particle surface. The latter effect reduced the value of interfacial conductivity, i.e. prevented the voltage drop of the polarizing field. Matching of polymer conductivity and piezoceramic particles by determining the optimal polarization temperature was carried out as well.

Credit availability to construction sector entities determines for thin-capitalized construction firms the possibility of survival during the crisis and of efficient growth during the economic recovery. The main lenders for construction sector entities are commercial creditors (suppliers) and banks. Although their credit policies are similar, debt to commercial creditors dominate in the balance sheets of borrowers, because of customary business practices in construction industry and regulatory distinctions.

This article describes an algorithm for finding the linear functional quality that describes the order of preference on a set of technical systems. The basic idea, which implements the algorithm is to break the complex solutions of the preference (for many variables) into a number of simple solutions (in pairs of variables), followed by a formal synthesis of the overall solution.
