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.
In recent years, the without-cable system for the decline-directed and horizontal drilling has attracted of significant research interest. Advanced telemetry system of transfer measurement information for Measurement-while-drilling is designing on the system level in this study. Evaluation of the use of video pulse signal in this system is carried out. The structure of transfer microwave pulse transmitter based on Gunn diode is considered. Characteristics of transmitter are resulted.
