Probabilistic neural networks with macrolayers are used in systems for support of decision-making in differential diagnosis of cardiovascular diseases. The neural network contains two macrolayers. Macrolayer 1 is based on the Bayesian probabilistic formalism. Macrolayer 2 is based on uncertain logic of decision-making and provides classification into two classes. The neural network provides differential diagnosis of cardiovascular diseases. The subjective probabilistic factors are estimated in points or percents. The expert estimates the probability of the zero hypothesis on the basis of a posteriori probability of the alternative hypothesis. © 2013 Springer Science+Business Media New York. Source

An algorithm for allocation of slow waves and respiration rhythms from electrocardiosignal using quasi-periodic signals of living systems is described. The algorithm is based on detection of amplitude and morphology of cardiosignals. The algorithm allows slow and respiratory waves of cardiosignal to be localized using window Fourier transform. © 2013 Springer Science+Business Media New York. Source

Two subsystems of living systems were studied as quasi-periodic synchronized processes x 1(t) and x 2(t). The signals were monitored during time interval T, which was determined according to the goals of the tests and the origin of processes. The phase portrait of the system was formed in the framework of references x 1(t) - x 2(t) within the time interval T. The portrait outlook was plotted. Fourier descriptors of the outlook were calculated. The system was classified in the space of Fourier descriptors. © 2013 Springer Science+Business Media New York. Source

The possibility is demonstrated of significant surface hardening for steel objects operating under abrasive wear conditions by carburizing, which provides the formation of a considerable amount of excess cementite within diffusion layers. © 2015 Springer Science+Business Media New York. Source
