The detection and localization of structural damage in a stiffened skin-to-stringer composite panel typical modern aircraft construction can be addressed by ultrasonic-guided wave transducer arrays. However, the geometrical material complexities this part make it quite difficult to utilize physics-based concepts scattering. A data-driven deep learning (DL) approach based on convolutional neural network (CNN) is used instead for application. DL technique automatically selects most sensitive...

Current fusion devices usually implement distributed acquisition systems for the multiple diagnostics of their experiments. However, each diagnostic is composed by hundreds or even thousands signals, including images from vessel interior. These signals and must be correctly timestamped, because all information will analyzed to identify plasma behavior using temporal correlations. For without synchronization mechanisms timestamp given another device with timing capabilities when signaled...
