Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Proposed in the paper are the new algorithms for vibration-based diagnostics of existing defects in hydraulic units. They are based on an artificial neural-like network, which implements spectral analysis of vibroacoustic signals using threedimensional amplitude-frequency-temporal spectra of these signals, such spectra being obtained using discreet wavelet transformation.
