In this article, we examine barotropic geostrophic currents in a Cartesian and the polar coordinate system. The polar system is preferable for analysing geostrophic currents, since radial symmetry is intrinsic to these currents. We obtained ratios between the general hydrodynamic properties. The expressions of geostrophic current velocity components in terms of pressure were the most important among them. The procedure of deriving the expression of vorticity in terms of pressure was carried out. We determined that isobaths coincided with streamlines in stationary barotropic geostrophic currents. The radially symmetrical geostrophic current was studied in detail.

In this paper, we describe three levels of a visual meta-language for hybrid intelligent systems of electrical grid management: 1) hierarchies of resources, actions, and properties; 2) spatial and operational-technological structures; 3) situations and states. A visual metalanguage qualitatively changes the performance of the subject of management and allows them to recognize a problem at a glance and see a workable solution without drawing logical inferences.

In this article, we consider techniques for, and approaches to, the organization of various stages of heterogeneous solution design in small expert teams. Simulating the heterogeneous design of team solutions by hybrid intellectual multi-agent systems will contribute to the efficiency of problem-solving in dynamic environments. We propose a structure of a hybrid intelligent multi-agent system for implementing the techniques considered.

In this article, we develop a technique for the automatic detection of nonreflective events in the fiber-optic section of a communication line, using wavelet transforms. We establish what wavelet-generating function is optimal for our case. This technique will contribute to the information value of traces of events observed in various inhomogeneities of a communication line.
