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.
AbstractWe report on the results of experimental investigations on determining drag and lift coefficients for a system of two parallel rotating cylinders. The results show that with increasing the distance between rotating cylinders, drag and lift coefficients decrease. It has been established experimentally that the distance beginning with which cylinders almost stop acting on each other is 0.4 of the diameter of these cylinders.
