Detecting damages on surface

Periodic structural health survey is very crucial to guarantee the safety and serviceability of civil engineering structures. The study "Applications of Gaussian Steerable Filters in detecting structural damages" aims at developing a computer vision tool to detect defects on surface of civil engineering structures by means of Gaussian steerable filters. This tool has been developed with Visual C#. NET to facilitate its implementations. The developed software programs have been tested with images containing various defects such as crack, pothole, and spalling.

Periodic structural health survey is an important task to ensure the safety and serviceability of buildings. This study aims at developing a computer vision tool to segment images capturing surface of reinforced concrete structures. The image processing technique of Gabor filter is used with k-Means clustering algorithm and principal component analysis to automatically segment damages on concrete surface including spall, crack, bughole, and stain.

A further check on the refrigerant charge is described on pages 33 8. When vapour charging a system with an azeotropic refrigerant such as R502 the refrigerant cylinder must always be kept in a vertical position to prevent the possibility of liquid refrigerant from entering the compressor. This can create a dynamic pressure when the compressor starts, causing damage to valves or may even break piston connecting rods and damage pistons. The liquid refrigerant will also flush lubricating oil from bearing surfaces.
