Technology of Accumulating Sampling at Mass Spectrometric Method of Tightness Inspection

Abstract

The method of mass spectrometric method for total inspection of product tightness at atmospheric pressure is shown.
 This method can be applied to products of any size and configuration with a given inspection sensitivity.
 The method does not require vacuumizing of the monitoring objects.

BIM and CCD imaging based visual inspection method for airport road surface defects

“…BIM forward model is a 3D digital information model that integrates architectural and geometric information at the completion stage of an engineering project [4][5]. For airfield surface disease management, the original BIM model is a carrier of the spatial structure of the airfield surface, and the level of detail of the model is determined by the maintenance needs and the degree of disease distribution [6].…”
