Lightning characteristics based on data from the Austrian lightning locating system [PDF]
IEEE Transactions on Electromagnetic Compatibility, 1998 We compare various lightning characteristics measured by the Austrian lightning locating system [Austrian Lightning Detection and Information System (ALDIS)] with those found in the literature. The latter are typically based on measurements of lightning electric fields.

IET Networks, EarlyView., 2022 Abstract 3D scanning is rapidly becoming a key maintenance tool. Aerospace was a pioneer in adopting 3D scanning technology because aircraft manufacture and maintenance require precision. Monitoring deterioration, removing components for maintenance, and verifying covert operations are not practical or helpful without technology.
