In exploration geophysics, the first arrivals on data acquired under complicated near-surface
conditions are often characterized by significant static corrections, weak energy, low signal …

To identify accurately the location of microseismic events generated during hydraulic
fracture stimulation, it is necessary to detect the first break of the P-and S-wave arrival times …

Ultrasonic non-destructive testing (NDT) technology has been widely used for defect
inspection of concrete structures in civil engineering. However, most of the current data …

Manually picking regularly and densely distributed first breaks (FBs) are critical for shallow
velocity-model building in seismic data processing. However, it is time consuming. We …
