Forecasting of open system behaviour

Abstract

Two dynamic models of the forecasted behaviour of an open thermodynamic system under given expected variations in the open system behaviour have been obtained. The two dynamic models have been presented as two machines. Each machine is made up of a closed system, which is obtained from the open one by isolation, and an environment. The first machine is driven by the diffusion between a closed system and an environment, caused by the expected variations in the power of the closed system; it is characterized by current and power spectra; it has two modes of diffusion of impulses and one mode of evolution, the transition between these modes being dependent on the energy of diffusion of impulses; and it is a synchronous system. The second machine is driven by the diffusion between a closed system and an environment, caused by the expected variations in the power of the environment; it is characterized by the probability density of the forecasted behaviour; it has two modes of diffusion of powers and one mode of evolution, the transition between these modes being dependent on the energy of diffusion of powers; and it is a tracking system.
