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.
A simple yet powerful procedure for an echo attenuation in signals is introduced.The presented method involves no external reference signal.It is based on comb FIR filtering.To the advantages of the described method belong the simplicity and performance which are beneficial in real time implementations.For illustration, a simulation of the procedure is included.The efficiency of the presented method is demonstrated by a real time implementation on a digital signal processor.
