Abstract: The article reviews the current state of large-scale
studies about the impact of electromagnetic field on natural
environment. The scenario of investigations – simulation of natural
conditions at the workplace, taking into consideration the influence
both low and high frequency electromagnetic fields is shown.The
biological effects of low and high frequency electromagnetic fields
are below presented. Results of investigation with animals are shown.
The norms and regulations concerning the levels of electromagnetic
field intensity are reviewed.
Abstract: The new idea of analyze of power system failure with
use of artificial neural network is proposed. An analysis of the
possibility of simulating phenomena accompanying system faults and
restitution is described. It was indicated that the universal model for
the simulation of phenomena in whole analyzed range does not exist.
The main classic method of search of optimal structure and
parameter identification are described shortly. The example with
results of calculation is shown.
