Lane cracks are one of the biggest threats to pavement conditions. The automatic detection lane can not only assist evaluation road quality and quantity but also be used develop best crack repair plan, so as keep level ensure driving safety. Although extracted from images because gray intensity pixels is lower than background intensity, it still a challenge extract continuous complete three-lan...

The state of Victoria in Australia has many major roads assets. These roads, stretching about 196,000 in km, have to be maintained and managed by VicRoads, the road authority of Victoria[1], and the local councils. Pavement Management Services (PMS) [2] company was employed by VicRoads in 2002/3 to do the analysis and detection of the pavement cracking in Victoria. PMS uses up to five industria...

A new approach to microwave eddy current testing for surface cracks in metals involves the use of ferromagnetic resonance in a small garnet crystal placed close to the surface to be tested. It is well known in this case that the induced eddy currents on the metal surface cause a strong displacement of the ferromagnetic resonance frequency. The presence of a crack on the surface produces, by dis...

This paper addresses the fault detection of a cracked cantilever beam using a hybrid artificial intelligence technique. The hybrid technique used here uses a fuzzy-neuro controller. The fuzzy-neuro controller has two parts. The first part is comprised of the fuzzy controller, and the second part is comprised of the neural controller. The input parameters of the fuzzy controller are relative dev...
