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.
The technique of express diagnostics of girder spans is presented, which makes it possible to determine the technical condition of girder spans of railway bridges. The technique is based on the analysis of the response of the structure to a small impulse effect – "a person's jump". Application of this technique will increase the service life and reduce costs for the current maintenance of railway bridges.
