The authors propose a method for determining the height of bus rollover to access body structure strength according to the Rules the United Nations Economic Commission for Europe № 66 (UNECE). Besides, it will allow to result in optimum value height of bus rollover with different dimensions. It is necessary to get more reliable information of body structure strength. For this purpose in procedure of tests it is suggested to enter the additional stage of calculation of the height of rollover before setting of transport vehicle on a rollover platform.

At present the results of a visual inventory of most of the water bearing structures in Russia is in a state that requires a major overhaul. Practice shows that, after this period of time, facilities continue to operate without being replaced by new ones, and sometimes even without a thorough reconstruction, to restore and reconstruct the existing structures on the basis of emerging new and previously used reliable technology. The object of the study was considered Tashla underwater pipeline right-Yegorlykskaya channel. In the numerical formulation of mathematical experiment task was to scientifically determine the reliability of structures for such a long life (50 years), with different types of defects and damage. All calculations were performed on a certain software product SolidWorks, which is based on the method of finite elements and superelements.

Current article presents the results of research, aimed at raising the effectiveness of automatic prosodic analysis of speech. During the research the PC program that performs recognition of seven emotional states using 16 features of speech signal was developed. Effectiveness of recognition of seven emotional states was estimated during the experiment with material of Berlin database of emotional speech. The result showed rising of mean probability of correct recognition, in comparison with known analogs.
Keywords: speech, intonation, emotions, speech
The work is devoted to the development of an intelligent system for monitoring high railway embankment, which allows to analyze its condition and make early solutions to manage the safety of vehicles. The main features of the system and its difference from known analogs is taking into account the dynamic effects of vehicles on a high embankment at different climatic conditions. This paper describes the main stages of building the monitoring system, which includes: selection of objects for monitoring, computer modeling of the interaction of the rolling stock and a high embankment, the algorithms required for the development of management decisions.

The article deals with the analysis of current legislative mechanisms of state policy implementation in the sphere of energy saving and energy efficiency. A number of crucial measures highlighted needed to ensure fulfillment of federal legislation requirements on energy efficient equipment and products while implementing state and municipal procurement procedures. The article notes problems occurring while implementing those requirements resulting from the absence of energy efficiency criteria and products life cycle cost while assessing and comparing applications. The article analyses the role and capacities of Moscow city which was selected as a pilot region to introduce energy efficiency labels and to ensure legislative and normative framework for order placement for municipal needs on the basis of energy efficiency standards and labels. The article points out that currently valid authority of the city touches on not only effective implementation of federal legislation but also issues related to the development of regional legislative framework.
