Turbine blade profile of curves Bezier
Vinogradov L.V., Alekseev A.P., Kostjukov A.V.
Abstract
An article presents profiling turbine blades The computer program in Mathcad is an element of CAD design system turbine. Blade profile outlines three curves Bezier: (back profile — one parabola (Bezier curve of order 2); trough — two parabolas (Bezier curves of order 2). In the construction was given the maximum thickness of the profile.

Overhaul time of gas turbine by temperature change
Antipov J.A., Shatalov I.K., Sobennikov E.V., Belova E.V.
Abstract
Overhaul time of gas turbine by temperature change. Overhaul time of blades decreased on 25—35% when temperature slow changed owing to work on part load. Overhaul life of cooling blades bay be increase if air flow control retain permanent blade temperature.

Hotel management-process using the relational approach
Soro Mamadou -., Vnukov A.A.
Abstract
In article it is considered the questions connected with the theory and practice of development and research of management information system by hotel complex. The server part of the software, allowing carrying out the main business processes and functions on management of hotel complex with MS SQL Server DBMS application is developed. For adoption of the correct and reasonable operational and strategic decisions the system of modeling of business management according to an integrated indicator of quality of the enterprise and services rendered to them is created. The tool for monitoring and the analysis of information on efficiency of business processes are indicators of business processes. The business analytics on the basis of mathematic-game conception of modeling with the forecast promotes obtaining objective information on the current situation and tracking of influence of different factors and occurring processes on profitability of hotel complex.

Light environment of facilities for sports and health-improving exercises
Bykova G.I., Korshunova N.N.
Abstract
Natural light is essential for the normal functioning of the human, so for sports facilities are very important to the orientation of the halls, where the training. Optimal is a latitude orientation, and the Windows of the rooms should go to the North side, with an accuracy of 30%. The lighting can be used as the side, and the upper light. The best solution is a variant of combined lighting, where major is the upper light, and the side Windows with lighting devices are used as additional.

Information technologies of decision support
Bogoslovskaya A.B.
Abstract
The methods of making management decisions in the company are considered. The teamwork of making decision is shown. The stages of decision-making are presented. It is noted that the collective decision-making is based on scientific and practical approach with the selection of optimal solutions through the computer processing. The purpose of information technologies of decision-making support is to develop a solution as a result of the iterative process.

Some features of natural reservoir in basis of the field White tiger (offshore of South Vietnam)
Bestuzheva N.A., Romero Moisés -.
Abstract
The rapid growth of hydrocarbon extraction and consumption sets up under specialists an urgent task of searching deposits with law-yield and compound structure of NR also in basis rocks bedded in oil and gas basins. Not all cracking selvages are permeable and it is necessary supplementary indications that help differentiate cracking selvages according to their permeability. All cracks before Miocene age (generated before oil migration) filled with second minerals and are impermeable. The practically important conclusion is that only examination of new cracking systems helps to forecast some parameters of effective porosity and geometry of oil saturated cracked reservoirs of basis. Since oil migrated to pore-cracked surroundings of White tiger reservoir rocks late so all geological processes and effects before Miocene don’t have influence on oil and gas accumulation and present no more than academic interest.

Protection of Pipelines passing under the roads
Svintsov A.P., Nikolenko Y.V., Al-Harami Tami -.
Abstract
During the construction and operation of roads, it is very important to ensure the safety of pipelines of infrastructural life-support systems. To improve the reliability of ceramic and cast-iron pipes, when they pass under the roads, developed a technical solution to significantly reduce the impact loads from road transport on the pipes.
