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.

This article discusses the implementation of the Children's Art School in additional pre-service education programs. Additional education poses the problem corrections professional training plans and programs for the development of the educational process. The aim of any school , including the school of arts is - provide an opportunity for the development of multifaceted abilities of each student's development needs and readiness for self-education , and for this it is necessary to create the conditions for such an educational environment that will allow full self-realization of every child regardless of the family's capacity and power giftedness.

Design unique buildings and structures is a complex task requiring high qualifications, training and experience specific performers. The article describes in detail the contents of the various etapovproektirovaniya, the basic requirements and features, starting with the technical specifications of the project and finishing expertise. Outlines the features of pre-training, the issues that must be resolved before the start of work. We consider the load that must be considered and especially the calculations. The requirements on the development of specific technical specifications (CTS) on the object and scientific and technical support of the project (NTS) Particular attention is given of experimental studies of physical models of buildings and unique structures. The following material can serve as a basis for program and algorithm for the design of long-span and high-rise buildings and unique structures.

At the end of 2012 – the middle of 2013 pilot questioning among RGSU students was carried out. In total more than 330 students of the first and second courses were interrogated. The work purpose – measurement of dynamics of an emotional component of group installations in relation to a political order. The emotional component of group political installation was measured on technology of semantic differential. It was offered to estimate to respondents on 20 bimodal scales four types political about. Two ideal – ideally positive and ideally negative orders. And two real – local and central. In the linear approximation calculated levels of emotional perception of the political order in the vicinity of the averaged image of the real image of the ideal order to constructs used in the space of features. Perception of an order at the end of 2012 in Region: -0,21892, in Russia: -0,24154 . To the middle of 2013 level of perception decreased: in Region: -0,59429, in Russia: -0,43879 . For the considered period level of a relative deprivation also was analysed: in 2012 level is equal 0,523 and in 2013 made 0,555. Thus, to the middle of 2013 there is a small increase in level of a deprivation that correlates with deterioration of perception of a political order among youth.

Research represents the analysis of group political installations among students of RGSU in the period of the end 2012 – the middle of 2013. Studying of installations was carried out by means of questioning in which more than 330 young people were involved. Analysis of the data held in the linear approximation using descriptive statistics and factorization. It is received, in cognitive perception of a political situation in Region respondents treat slightly better, than a situation in Russia, thus in both cases level is negative. For 2012 perception level in Region: -0,23, in Russia: – 0,27 . For 2013 in Region: – 0,20, in Russia: –0,23. The level of relative deprivation is average and slightly increased by the end of the period : in 2012, the level is 0,523 and in 2013 was 0,555. The analysis of total level of a behavioural component was carried out by consecutive factorization. The behavioural component consists of two parts: assessment and activity. So, for the middle of 2013 estimated level of behavior was - 0,096, and activity level-0,268. Further on these factors the subsequent factorial analysis with identification of the general behavioural installation was carried out. For the end of 2012 the general level of a behavioural component is equal – 0,052, and for the middle 2013 this level made - 0,148. Thus, total level of a behavioural component of group installation in relation to a political order tends now slow transition from alienation to performance against an existing order.
