Labour market is a complicated social and economic system, which requires the necessity to consider a number of characteristic properties (stochasticity,nonlinearity,inertance,nonstationarity) for investigation and modelling labor market processes and phenomena. In this article the problem of optimum control of a labour market is mathematically formalized. This allows for regional system of a labor market to reach desirable indicators, namely the set unemployment rate.

  The current work considers the problem of arrangement optimization of non-convex polyhedrons into a minimal height parallelepiped container. The no-fit polyhedron based algorithm is proposed to solve described task. The no-fit polyhedrons are used not only for providing conditions of the polyhedrons mutual non-intersection but also for finding the placement points. The current paper provides the block diagrams and the pseudo code of the algorithm. Some examples and computational results are also given for public input data.

  The article is devoted to improving the performance of cryptographic transformations performed encoders stream ciphers made on the basis of the inner product generator. Such generators are a variety of clock-controlled shift register that can improve the statistical properties of the resulting sequence. The disadvantage is that to get a one character of sequence to submit several clock. The scheme of the inner product generator, based on the algorithm reimplementing feedback shift register recurrence, which allows for one step to produce a single character of sequence, is constructed and described in this article.

To improve energy efficiency of the Russian economy and the introduction of energy saving technologies is a strategic objective. The housing sector in Russia is second largest manufacturing sector of final energy consumption: more than ¼ of total energy consumption and 45% of heat consumption in the country. Most of the apartment buildings is characterized by low efficiency of energy consumption: the energy they now consumed an average of one and a half times higher than in countries with a similar climate. Today, there are technical solutions that reduce the loss of resources in residential buildings while providing comfortable living conditions, which ultimately should lead to lower cost of the housing.

As a notable desire to invest in the safest of assets - real estate, an increase in construction in the Russian Federation. However, despite the emergence of new technologies and methods of works, materials, machinery and equipment are still some problems - the lack of adequate procedures in the organization of the construction process, which affects the duration of construction. To date - this is the main factor. And its value depends on the cost of borrowed money, the loss of the frozen funds related to the timing of input and start to use the object to the destination. Therefore, to achieve the goals, it is necessary to develop information technology construction industry with the interaction of design and construction companies to provide timely information to manage the construction industry.
