This paper proposes a nondestructive evaluation method based on deep learning using combined ground-penetrating radar (GPR) and electromagnetic induction (EMI) data for autonomic accurate estimation of the cover thickness diameter reinforcement bars. A real-time object detection algorithm—You Only Look Once–version 3 (YOLO v3)—is adopted to automatically identify bar reflected signals from rada...

The neutron capture gamma-ray technique was used for the analysis of Cu-Ni alloys, widely used in industry. The two elements, which are very close in atomic number, have widely separated characteristic capture gamma quanta. A sensitivity of 7x10 counts per unit thermal neutron flounce per 1% change in Ni/Cu ratio was obtained. Samples of any shape can be analyzed without a need for any special ...
