Application of 3D scanning technology in Royal Malaysian Air Force Industrial Revolution 4.0‐based aircraft maintenance

open access: yesIET 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.

LMA observation of upward flashes at Säntis Tower: preliminary result [PDF]

open access: yes, 2018
Lightning striking tall towers is mainly of the upward lightning type, which is characterized by the absence of a first return stroke and the presence of an initial continuous current (ICC) with or without superimposed pulses.

The Lightning Current Measurement Based on Wavelet Transform

open access: yesModern Applied Science, 2010
Summary: The current model of the lightning process is established and simulated in this article, and aiming at the disadvantage that the hardware filtering de-noising method adopted in the general lightning measurement system can not effectively separate signals and noises in same one frequency channel, this article uses the wavelet transform to ...

Comparison of lightning return stroke channel-base current models with measured lightning current

open access: yesBulletin of Electrical Engineering and Informatics, 2019
Electromagnetic pulse radiation produced around the lightning stroke channel has caused the disturbance to the microelectronic industry, especially to disturbance of high frequency to electronic systems. Lightning channel-base current function (CBC) characteristics and parameters determine lightning electromagnetic field (LEMF) results obtained on the ...
