Abstract
Properties of the fields and power descriptions are considered. It is shown that the form of videopulses in a distant area is determined by a derivative from the form of impulse of current, given on Hertz’s dipole. Power descriptions of the electromagnetic field are proportional to the square of derivative from the form of impulse of current, given on Hertz’s dipole.

Selection of the optimal order for multivariate autoregressive model of electroencephalograms for patients with epilepsy
Introduction. Brain electrical activity signals (or EEG) by their very nature are non-stationary time series. This basically allows applying a set of mathematical-statistical analysis methods to them. One of the most com...
