UNIVERSAL COGNITIVE ANALYSIS SYSTEM "EIDOS-X+ +"
DescriptionThe "Eidos" system is working well for many years of use for researches in various subject areas and activities for a number of scientific disciplines related to artificial intelligence, knowledge representation and knowledge management. However, during the operation of the system, some of the shortcomings that limit the opportunities and prospects for the application of the system have been identified. Therefore, the radically new version of the system (the system Eidos X + +) was created, which overcome the limitations and drawbacks of previous version and includes new important ideas for its development and use as a software tool in system-cognitive analysis (SC analysis)

TURBULENT HEAT AND MASS TRANSFER IN WALL-ADJACENT SUBMERGED JET OF AIR
DescriptionThe analysis of heat and mass transfer in the wall-adjacent jet of gas under essential non-isothermal conditions is given. The calculated relations of chemi-cal erosion intensity of surface on the basis of integral correlation for the turbulent boundary layer are ob-tained. The presented calculations are successfully compared with the experimental results
