The paper considers the elements and specialities of the diagnostic in the medical field. There is also proposed the categorical kernel of the functional hybrid intellectual diagnostic systems with cognitive visualization of prob­lems in medicine. Such systems would give the opportunity to smooth the conflicting symptomatic data and would make the processes of negotiation of the diagnostic problem visible and contrastive.

The authors study the application of calculation method of radio signal attenuation in clouds and amplitude scintillations that take place during its propagation in the atmosphere. The paper describes the algorithm of attenua­tion calculation, created in MATLAB program and calculated resulting at­tenuation for Kaliningrad region of the Russian Federation. Additionally, the topic of estimation of total atmospheric attenuation is highlighted.

Paper is devoted to development of calculation method for optimal con­figuration of wind generators. Electromechanical features of permanent mag­nets synchronous generators with round rotor are researched, formularization is made for these features. Also mechanical properties of wind turbines with horizontal rotation axis are described. Reviewed theoretical materials allowed to develop calculation method of wind turbine parameters and gearbox param­eters for performing nominal output power with normal operation conditions. Simulation of wind generator in MATLAB software confirmed efficiency of proposed calculation method.
