Mechanisms of geometrical seismic attenuation

In several recent reports, we have explained the frequency dependence of the apparent seismic quality-factor (Q) observed in many studies according to the effects of geometrical attenuation, which was defined as the zero-frequency limit of the temporal attenuation coefficient.In particular, geometrical attenuation was found to be positive for most

Semantic segmentation of thermal defects in belt conveyor idlers using thermal image augmentation and U-Net-based convolutional neural networks

Abstract The belt conveyor (BC) is the main means of horizontal transportation of bulk materials at mining sites.The sudden fault in BC modules may cause unexpected stops in production lines.With the increasing number Vitamins of applications of inspection mobile robots in condition monitoring (CM) of industrial infrastructure in hazardous environm
