In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics ...

Defect detection requirements on the order of 10 defective parts per million (DPPM) are driving improvements in inspection ...

A picture snapped from the International Space Station (ISS) by NASA astronaut Nichole Ayers has captured a lesser-seen view ...

A new sensor based on complementary split-ring resonators is presented to detect sub-millimeter surface cracks. The sensing mechanism is based on perturbing the electromagnetic field around an ...

In the alternative current field measurement (ACFM) technique, the nonzero value of liftoff distance for the magnetic sensor acts as a low-pass filter on surface crack signals, causing errors in crack ...
