A mathematical model of the mechanism of anti-symmetric vortex at the confluence of fresh water to sea water, observed, in particular, the output of the Baltic Canal connecting Visla Lagoon to the Baltic Sea is constructed. It is shown in particular that the main reason the vortex formation in this case is the Coriolis force. Also analytically calculate the exact dependence of circula-tion rates from time to time for the three simplest forms of "language" of the intrusion of fresh water.

It is proposed a circuit of negative feedback for the reduction of phase noise. The circuit compensate the influence of amplitude fluctuations on the value of the average for the period of the oscillation capacitance of the varac-tors and thereby reduces phase noise VCO.

The possibility of an extended range of properties of shortwave antennas by creating an environment in constancy wave resistance is justified. On the base of model representations, the analysis of the appropriate changes on an-tenna systems of different designs, are implemented. This systems are based on asymmetrical vibrator.

A task of goals analysis in industrial object and a method of its solving based on using of the semiotic system of logical-and-linguistic type are de-scribed. The method provides objective analysis carried out by decision-maker and simulating of logically right goal setting in cases of incorrectness and in-completeness of subjectively formed analytical structure of goals.
