The following methods are used in the research: theory of the variable frequency drive and electrical machines, methods of operational calculus, theory of centrifugal bladed machines.

The device is the X-band Gunn diode hybrid-integrated power amplifier-transmitter. Its advantage is high efficiently and low current from bias. The pulse output power is about 15 Watt in short-pulse operating conditions, at 9 GHz central lobe frequency. Due to the MWD application, the special attention pays to circuit and repeatability of characteristics. Design and packaging is very tight and give a possibility to put device into the drilling gun.

We solve the problem how to define the important managerial factors which influence on small businesses' activity indexes, profit growth being one of the most significant.
