The main global trend of formation of modern society becomes a transition to the so-called "intelligence economy" based on intellectual resources, high-tech and information technology. "The economy of intelligence" - is not just intra-changes due to the emergence of new industries related to the dominance of intellectual capital and information and communication technologies. It reflects a system-wide change, at which qualitative changes affecting the structure and all levels of the social system, accompanied by a change of technological structure, social and political organization. In this regard, a growing need for research and generalization of experience of the leading countries that have achieved the greatest results in the development and implementation of effective public policy innovation, as well as to identify opportunities and limits of its use in the formation of Russia's long-term innovation policy.

Low heat transfer coefficient per unit area is main disadvantage of immersion cooling system. In the theoretical part of the study the main issue was to evaluate the influence of various factors on the convective heat transfer between the solid-liquid interface. The result of this part of study was conclusion that the type of fluid flow in the area of heat transfer is key factor of increase heat convective heat transfer of thermal contact. The Reynolds number is main characteristic of turbulence of fluid flow. Therefore in the experimental part describes study of the effect of the degree of turbulence of the fluid flow at the place of the thermal contact on thermal resistance of immersion cooling system. The design of experimental setup and its main parts is describe further. The result of the experiment is graphic of experimental curve of the thermal resistance of immersion cooling system from the Reynolds number of fluid flow of thermal contact between the solid-liquid interface. The study showed the possibility of local reduction of the thermal resistance of immersion cooling systems to maintain the quality of the thermal management of computing elements that emit significant heat. The results of the study is define the ranges of values of the Reynolds number of cooling system that allows the technical realization at the current dimensions of packages and sizes of microchips sockets.

The analysis of the gap pile Foundation of the bridge during construction the compressor station "Baydaratskaya" on the Yamal Peninsula, applying the technology of construction in the far North region, identified the cause of the destruction of pile Foundation (pile-rack). The analysis of deformation has been proven the urgency of the problem of deformation and destruction of the bridge piers on the border "water-air" in different traffic and climatic zones of Russia, including in the far North. Based on a practical analysis of the problem of the destruction we can draw the following important conclusions: - The destruction the bridge piers, piles in the area of "water-air", because of intense deformation and the requires external sources of protection. - Further study zone "water-air" is true in our time, and existing protection methods are not able to protect the structure from damage. - necessary practical research to identify ways to protect bridge piers in the area of "water-air". - necessary to control the state of the bridge's pillars after the construction of protective structures above the water level

The problem of optimal allocation of resources - one of the basic optimization problems to be solved in the design of complex systems, determining their structure and methods of operation, so this work is considered one of difference methods for solving inverse problems of non-uniform distribution of resources. The inverse problem of non-uniform distribution of resources formulated as follows. It is necessary to choose the amount of funds the option to specify distribution of units served by the product and to offer such means of their actions to a given level of performance means performing the task was achieved with the minimum of expense. The most common methods for solving inverse problems, various modifications of the method of random search, dynamic programming method. However, the use of these methods in some cases, particularly for large-scale problems, is not effective. Optimal elements, which turned into a row or column assigned to an optimal element from further consideration at this stage of the distribution, the process eliminated to provide an optimal plan of resource allocation in construction.

The article presents the investigation of ultrasonic treatment influence on the size of the stearylamine floccules in the aminobutyric emulsion and on the stability of received emulsions. It was found that the amine floccules in the original aminobutyric emulsion have a bimodal size distribution with small particles predominantly 900 nm and large particles with size of 5500 nm or more. It was identified that ultrasonic treatment leads to decrease the stearylamine floccules size in 13-25 times, dimensions of obtained floccules are between 35 and 220 nm. The dynamics of size changes of stearylamine floccules was studied. The stearylamine floccules were obtained in aminobutyric emulsions after the ultrasonic treatment with an intensity of 15-30 W/cm2. It was found that after ultrasonic dispersion the process of amine floccules agglomeration takes place, the duration of this effect depends on the intensity of treatment.
