Abstract
For the cardiovascular desease early diagnosis by the remote monitoring systems the fonokardiosyhnal (as periodically correlated random process) simultaneously registered with electrocardiosignal usage is proposed. An registered signal preproccesing procedure, groundet in this article, is carried out by the following algorithm: detrending procedure (the constant component of the signal (trend) reducing), smoothing (high noise suppression with minimal spectrum distortion and P-peacs offset locations), the P-peacs repeating intervals determination.

The study of technologies to improve physical-mechanical and chemical properties of reaction sintered ceramic materials on the basis of silicon carbide
The ways of improving physical-mechanical and chemical properties of reaction-sintered ceramic materials based on silicon carbide are described. Various means of processing ceramic materials are studied and analysed. The...
Influence of residual strain on the contact interaction of a hard punch and elastic semi-space
Calculating the strength of structural elements and mechanisms is one of the most important stages in the process of their design. As it is known [2], residual deformation is almost always available in the structural ele...
Methodology for the experimental research of reinforced cylindrical shell forced oscillations
In the paper the methodology for experimental studies of forced oscillations of a horizontally oriented cylindrical shell which is reinforced from the inside by stringers and bulkheads using the servo-hydraulic test mach...
Parameter justification for interworking relationship of elastic screw operating element with grain material
Famous constructions of auger operating elements with elastic surfaces and screw operating conveyors have been analyzed. New construction of auger conveyor with elastic screw surface was developed and designed. The influ...
Fluid-structure interaction in free vibration analysis of pipelines
We analyze the impact of the transported fluid on the natural frequencies of a pipeline. Solution of coupled acousto-mechanical problem for straight pipe is given by the Transfer Matrix Method. The equations for junction...
