Abstract
Singularities of development of new methods and the fast broadband space diversity systems of impulse amplitude and phase measuring and spectrometry, capable to measure temporary and frequency parameters of spatially distributed dynamic objects of various physical nature are considered. Information about practical em-bodying such systems and their technical features are presented.

Wavelet analysis of the electrocardioignals for detection of the posttraumatic myocardial dystrophy features
Introduction. The features of the traumatic disease's impact on the cardiovascular system are reviewed. Numerical experiments on electrocardiosignals of the soldiers injuried by mine explosion were held. The nature of th...
Decision of numerical problems with symbolic methods
Modern methods for numerical decision of linear systems guarantee successful results only for good systems. Decision of bad systems (bad conditional, singular) is already problem. This paper describes using symbol method...
