The paper deals with methods of preliminary analysis of sound signals to extract stable features in classifying the relay used in railway automation systems. The algorithm of the description of a sound signal on the basis of these attributes is offered.

The complex use of methods of nondestructive check for the automated diagnostics electromagnetic relays of railway automation the first class reliability is offered. The methods determination of their mechanical parameters are resulted, that allows to exc... see more

A method of mechanical and electric parameters control of electromagnetic relays without removal of protective casing is expounded in the article. Control of diagnostic signals obtained by three informative channels: electric, optical and acoustic has bee... see more

In the article one of variants of checking the operability of relay equipment for railway automation is examined with the use of method of noise diagnostics (an identification of noise signals on the basis of using the moments of density of probability di... see more

The subject of study in the article is the acoustic resistance of local areas of the biological tissues in vivo, depending on their pathology. The aim of the work is to develop a quantitative method for measuring the acoustic resistance of local areas of ... see more

The article is devoted to analysis of the errors that occur when acoustic diagnostics of stress state for shaped profiles of metal structures. The analysis of methods for acoustic diagnostics of stressed state of shaped profiles was conducted using mirror... see more
