Intermittent - Intermittent errors show up on an irregular basis and can be indicative of a nascent problem, such as when a hard disk logs a series of write errors, showing that the drive may fail.
Based on an analysis of the mechanism of wave action on the revetment, formulae for block thickness under the actions of regular and irregular waves were obtained through a series of stability tests.
The steady temperature field in irregular plane domain with radiation heat exchange boundary is analyzed by the boundary discrete method, and the solution in form of series is obtained.
