Aiming at the coal mine personnel positioning method based on wireless sensor network technology, contrasting with advantage of now-existing feasible methods, consulting with traditional trilateral positioning, this paper proposed weighted trilateral localization method based on RSSI ranging. In order to ensure the precision of distance measurement, analysis the cause of error of RSSI, improved the...
The switching transients of electrical and electronic equipment (such as high-voltage isolation switch or circuit breaker) can generate various types of harassment transient immunity. This paper takes the electrical fast burst (EFT/B) as an example to specifically introduce the uncertainty of which couples pulse composed by numerous electrical fast transient to the power port of electrical and electronic...
Parameter estimation of small samples is a valuable research problem in various test domains. Because of the complexity in determining the probability distribution, it is difficult to use a traditional probability theory to process the samples and assess the degree of uncertainty. Based on the grey relational theory and the norm theory, the grey distance information approach for small-sample processing...
