The research is devoted to a method of diagnostics and quantitative analysis of chaotic synchronization in the presence of noise. We analyze how the additive white normal noise influences the accuracy of the measurement of synchronization of chaos. We also propose a new modification of the standard algorithm, which significantly reduces the sensitivity of the method to the noise.

The hydrodynamic equations of inviscid compressible fluid are converted to a form suitable for development of self-consistent theory of interaction of hydrodynamic flows with resonators and periodic structures by analogy with the theory of microwave electronics devices with crossed electric and magnetic fields. We consider excitation of the acoustic velocity fields by the sources provided by vorticity in the flow.
