EXPERIMENTAL RESEARCH OF HYDRODYNAMICS SOURCE CYLINDRICAL COLLECTORS OF HEAT EXCHANGERS
DescriptionIn this article, we represented the scheme and parameters of a pilot model of a source cylindrical collector of the heat exchanger. Influence to a field of velocities on withdrawal from a collector of various nonuniformities of submission of a cost of the heat-carrier on an input of a collector, and influence of a hydraulic resistance on withdrawal from a collector on uniform of a stream of the heat-carrier is experimentally established

RESEARCH METHODS OF WATER PURIFICATION FROM POLLUTION WITH PETROLEUM AND PETROLEUM PRODUCTS
DescriptionThis article provides an overview of the currently existing methods of purification of waters from pollution with petroleum and petroleum products. The most popular cleaning ways and new emerging technologies are considered. For each method of combating with petroleum pollution the circumstances and the factors are given, under which the application of this method is the most efficient and cost-effective. The article briefly describes the technology of each method, and its main strengths and weaknesses, particularly the use and quality of water purification

Description
The article presents an attempt of generalization of problems of the theory of mathematical description of synchronous machines with an arbitrary number of windings of three-phase and the arbitrary location of these windings in the space of the machine. We have also considered the peculiarities of choice of rational system of relative units in the mathematical description of such a machine

DETECTION OF DEVIATIONS IN CONTROLLING SYSTEM (FOR EXAMPLE, MONITORING THE LEVEL OF FLIGHT SAFETY)
DescriptionControl charts are proposed to use as a tool to detect deviations in the controlling system. This proposal is considered for monitoring flight safety. Possibility of use in practice of airlines of a new indicator of flight safety level and a new method of its monitoring is discussed. As an indicator the ERC of ARMS group, and as a method of monthly and weekly monitoring – a method of the cumulative sums are offered

MANAGEMENT PROCEDURE OF LOGGING ROUTES OF OIL AND GAS PIPELINES AT FOREST TERRITORIES
DescriptionProcedure of management by process of routes logging is developed for linear objects (oil and gas pipelines and power lines) by petrol saws, delimbing-bucking machines and timber transport road trains in wood territories. The documents and the performers providing management of operations and the registration of the quality of the works, the resources and the equip-ment, used in the process of logging are defined

FORMATION A STRATEGY OF SOCIOECONOMIC SYSTEM’S DEVELOPMENT IN THE RESOURCE-LIMITED CONDITIONS
DescriptionIn the article the structural model of the socio-economic system is presented as a management object. We have described the levels of creation of mathematical estimation model of the socio-economic system’s state, which on the basis of the aggregated estimation of management factors array allows selecting the primary purposes of socio-economic system’s development. The main socio-economic system’s processes in the production of goods and services are presented as complex activities. Determining methods for the modern market share occupied by socio-economic system, socio-economic system’s actual share offers on the region market, the demand for goods and services in the region, the amount of income from the activity by mathematical estimation model of the socio-economic system’s state are offered. The amount of the budget is defined as the sum of the socio-economic system profits from commercial activities and the size of public funding on the orders. Evaluation of resource support for activities described in the article is proposed. The way to solve the actual problem management - determining the socio-economic system’s priorities with limited material and financial resources is offered. We have also presented an algorithm of determination of aims of the development on the basis of estimation model of the socio-economic system’s state, foreseeing determination of external and internal factors on directions activity and forming of their aggregated estimations. The operative management in a socio-economic system allows us to react immediately to changing of key indexes of the systems and also allows using the limited resources rationally, which is very actual in modern economic conditions
