THE MECHANISM OF THE CURRENT INVESTMENT PLANNING IN THE MANAGING OF THE ECONOMIC SECURITY OF AN ENTERPRISE

This paper is focused on investment planning in the enterprise economic security management. The actuality of the research is determined by the need for the identification and usage of the adaptation enterprise system in Russia in the current circumstances of the domestic problems and changes in the world economic relations. In work was formed the mechanism of realization the current investing planning (CIP). Besides, authors have highlighted the stages that provide factors of economic security of an enterprise in a short- and medium-term perspective. The research aim is in the development of the mechanism of the practical realization of the current investment planning on the base of its logical structure and the investment program of the business entity. The methodological base of the research was: the dialectical materialistic method, the method of the unity of logical and historical, the methods of the induction and deduction, analytical groups and also such scientific methods as the analysis and synthesis, the logic, the graphic method of the information interpretation

Optical vector network analysis of ultra-narrow transitions in 166^{166}Er3+^{3+}:7^7LiYF4_4

We present optical vector network analysis (OVNA) of an isotopically purified $^{166}$Er$^{3+}$:$^7$LiYF$_4$ crystal. The OVNA method is based on generation and detection of modulated optical sideband by using a radio-frequency vector network analyzer. This technique is widely used in the field of microwave photonics for the characterization of optical responses of optical devices such as filters and high-Q resonators. However, dense solid-state atomic ensembles induce a large phase shift on one of the optical sidebands which results in the appearance of extra features on the measured transmission response. We present a simple theoretical model which accurately describes the observed spectra and helps to reconstruct the absorption profile of a solid-state atomic ensemble as well as corresponding change of the refractive index in the vicinity of atomic resonances.Comment: 4 pages, 5 figure

Application of double electrode welding as the way to increase welding productivity of fillet welds of bridge structures

One of the ways to solve the task to increase productivity and obtain an enlarged leg in one pass is the use of two-electrode submerged arc welding (welding with a split electrode). When testing this welding method with respect to welding bridge metal structures, it was found that the quality of the welded joints and the productivity of the process substantially depend on the positioning of the electrodes relative to the groove. However, for the effective implementation of this method, a comprehensive study of its functionality for welding of bridge metal structures is necessary to conduct. An effective tool in solving such problems is physical and mathematical modeling, which allows without running a large number of experiments to study the features of the formation of fillet welds. To carry out this analysis, we used the previously developed physical and mathematical model of weld formation in single-arc submerged arc welding, added a description of the spatial position of the split electrode relative to the joint and defined the distribution of the heat flux and pressure of the double arc. It was found that the location of the electrodes with the lagging arc on the web provides better weld formation. © Published under licence by IOP Publishing Ltd
