This paper proposes criteria for the optimal choice of a database management system (DBMS), based on the requirements to this system. Empirically assessed criteria and method of analytic hierarchy process for decision making were used to carry out the comparative analysis of several DBMSs, implementing relation data model and having similar functionalities. The obtained matrixes of pair-wise comparison are examined for concurrence by calculating indices described in the article. As a result, the database management system for the own project is rationally chosen.

The article highlights the issue of conservation of water and energy resources, the dependence of its decision on the environmental responsibility of business entities and tactical goals towards environmental management.  Also the essence of the work carried out in the production of ammophos is described (Hydrometallurgical plant, Lermontov town), which is a good example of solving one of the many tactical tasks in the direction of environmental management. Specific purpose of the work was to identify the savings reserves of energy and natural resources. The application object of the study is the energy-intensive production of ammophos (fertilizer complex of nitrogen and phosphorus compounds), in particular the boiling-down of ammoniated pulp. The load decrease by evaporated water by 75% is achieved the implementation of technical solutions in terms of sealing pumps work (replacing inefficient crevice seal on a metal face seal) installed on the circulation line of ammoniated pulp. This reduces the coolant flow for boiling-down of high pressure steam and drinking water saving, which is the raw material for the production of fluid. Ecological and economic efficiency of the proposed solutions is confirmed by the calculation of the expected technical and economic parameters, performed on the basis of data generated in monitoring: coolant saving - 3039 Gcal / y; 2430 rubles / g; drinking water saving - 11,477 rubles.

Universal method of optimal control synthesis offers a versatile method for the synthesis of optimal controls provides a solution to the synthesis problem for the class of piecewise constant functions for Lagrangian dynamical systems, the shape of the control law depends only on the structure of the cost functional and does not depend on the structure of the existing system of generalized forces. The effectiveness of the method is confirmed by a minimum of computational costs, as well as the maximum rate of convergence and accuracy to achieve the desired trajectory in comparison with the known solution for example has become a test for testing various control methods for the synthesis problem of a simple pendulum.

Thermal treatment of Fe-Co-V as an instrument to improve soft-magnetic material devices quality
The process of optimizing the thermal treatment Fe-Co-V alloys used in the magnetic torque motors is studied in order to improve the magnetic properties. It is shown that to achieve high and stable magnetic properties of the alloy it must be annealed in vacuum using inactive coatings. Regime of the annealing process depends on the quality of the original alloy. Quality verification is carried out by measuring the magnetic properties of the control samples . Identifying optimal annealing regime is based on the analysis of a phase diagram of Fe-Co alloy. In connection with that the research of influence of the heating rate , maximum temperature and holding time , cooling rate on the behavior of the magnetic parameters of the control samples is carried out. It was found that the improvement of the magnetic properties is achieved by increasing the exposure time to 6h at the cooling rate of 100 °/hr. As a result a reduction of the coercive force (60 ÷ 50 ) A / m to (28 ÷ 32 ) A / m and increased magnetic induction of technical saturation from (2,0 ÷ 2,10) Т to (2,20 ÷ 2.26 ) T. for Fe-Co-V alloy are achieved. Research of the exposure time and the cooling regime caused a decrease in coercive force of the Fe-Co alloy.
