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

This work is devoted to the generalization of difference method of the spatial characteristics onto the case of the plane problem of wave propagation in a rectangular area of finite dimensions with breaks in the boundary conditions. On the basis of the developed in the work the numerical method it is obtained the calculated finite - difference ratio of the dynamic problem at the singular point of the lower border of the rectangular area, which is the point pairing of fixed and free parts of the boundary. The results of the study are brought to the numerical solution.
