In the article are introduced research results of physicochemical properties of ammonium nitrate – potassium nitrate water system at 25o C. The literary source analysis is performed that no clear opinion about solid phases composition. The different composition double salts, solid solution and eutectics are identifies. Appeal is specifies a look and properties of formed structures. Methods of differential thermal analysis and X-ray diffraction have been establishing that the equilibrium solid phase of the studied system represents two types of solid solutions. A first type based on the III phase of ammonium nitrate crystal latitude (at the content of nitrate of potassium to 20 %) and a second type based on the potassium nitrate rhombic syngony (at the content of nitrate of potassium more than 80 %). Crystal cells parameters of being formed phases submit to the Vegard rule. The ammonium nitrate sample (at the content of nitrate of potassium more than 12 %) keeps phase stability at the temperature range minus 50 to plus 100о С. Burst in components miscibility at the potassium nitrate concentration range 30 to 80 % is observed.

At the present time in most countries of the world are being actively developed and introduced intelligent technologies necessary for creation of reliable and effective intellectual energy systems. Intellectualization of distributive electrical grids will move energy system to a new level of automation. Evenly distributed electrical grid of hexagonal type was offered. The principle of creation a grids was described, a typical scheme of universal electrical load unit was proposed. The key advantages of the hexagonal network was reviewed. The estimation of the reduction of the level of losses during electricity transportation was made. The increase of the level of reliability, the factors affecting the probability of faultless work were determined. Evenly distributed grids of hexagonal type will build energy system based on Smart Grid and solve existing problems: lower quality of electricity, the shortcomings of the power reserves, high density of electrical loads and high energy losses. Project implementation should be carried out in stages: from pilot project to implementation in big cities.
Work is executed with financial support of Ministry of education and science of the Russian Federation (state contract №14.516.11.0104 from 14.10.2013).

Case is an event that took place in the past and can be an example for similar steps in present. Case-based reasoning (CBR) is a methodology of finding a decision based on previous experience. The main difficulties in CBR are recognition of present situation of decision-making and finding similar case in the past. Making a decision in the field of purchasing drugs is a quite difficult and many-valued task with a plenty of various parameters, which however might be solved with the help of CBR. CBR is an important and perspective area of artificial intelligence (AI) decision support systems. Constantly growing research amount has already led to breakthroughs in theoretical part of AI and in AI-based applications. The general case model and formula for determining cases similarity is suggested in this work. Application of the formula will help determine similarity of cases and make the better decision.

For miniaturized vacuum klystron type devices utilization of a double- gap strip-line cavity with suspended ceramic substrate is very promising.
The two-mode operating mode of such cavities practically isn't studied enough; so there is the great scientific and practical interest for research of electrodynamic characteristics of cavities during multi-mode operation that correspond to simultaneous excitement of anti-phase and co-phase modes in a double gap.
In this article results of the 3-D numerical modeling by means of the Ansoft HFSS code are presented, and also the experimental results of the electrodynamic properties of the half-wave double- gap cavity with the suspended ceramic substrate are submitted. Optimum parameters of this design, allowing to carry out simultaneous excitement at multiple frequencies with frequency rate (K=2) are determined.
In such cavity high values of unloaded Q factors isn’t need because dielectric losses and conductor losses can be compensated at the expense of the negative electronic conductivity that brought by modulated electronic beam. The operating mode with frequency rate can be used for increasing of efficiency of generating and amplifying micro devices with filament cathode and matrix field emission cathodes.
