This paper presents a variational Bayesian-based adaptive unscented particle filter (VB-AUPF) to improve the positioning accuracy of BDS/INS integrated system under the condition without accurate measurement noise covariance. This method approximates the joint posterior distribution of states and measurement noise by using variational Bayesian approach on each time step. Based on this, the measurement...
Information fusion using evidence theory in wireless sensors networks has been used extensively to identify targets because it offers the advantage of handling uncertainty. But the classical Dempster’s combination rule cannot deal with highly conflicting information because it often generates counterintuitive results. In this paper, a new weighted evidence combination approach is proposed to solve...
With the development of three-dimensional low temperature co-fired ceramic (LTCC) packaging substrate, the internal microscale structures have great effect on the strength, toughness and lifetime of LTCC microsystem, where the study of local or nanoscale mechanical properties and microstructure is critical, especial for the prediction of the local failure behaviors. In this study, the nanoscale mechanical...
