In petrochemical process, the kernel task of avoiding abnormal situation is fault diagnosis of the process. As signed directed graph (SDG) can reflect the path of fault propagation clearly, it is a hot spot in fault diagnosis of petrochemical process currently. However, basic SDG is poor in resolution and insensitive to early fault, so it is needed to introduce other algorithms to solve the shortcomings...
As the health status of aeroplane structural components has direct influence on the flight safety, it is important to monitor the health status of structural components timely. In this paper, acoustic emission technology is used to monitor the health status of the aeroplane structural component. The acoustic emission health information from the aeroplane structural component is analyzed and disposed...
Error correction is an effective way to mitigate fault attacks in cryptographic hardware. It is also an effective solution to soft errors in deep sub-micron technologies. To this end, we present a systematic method for designing single error correcting (SEC) and double error detecting (DED) finite field (Galoisfield) multipliers over GF(2m). The detection and correction are done on-line. We use multiple...
