Research and development in microelectromechanical systems (MEMS) have made remarkable progress since the advent of the first electrostatic micromotor in 1987. Considerable efforts have been directed to the investigation of the failure mechanisms and reliability of electrostatic micromotors. This paper provides a brief overview of failure modes and(More)
Traditional interactive evolutionary computing approaches are usually susceptible to limited searching ability and human’s strong subjectivity. In response, by extending a traditional Belief-Desire-Intention (BDI) structure, a kind of affective learning agent which can perform affective computing and learning activities in human-computer interaction(More)
Global motion estimation (GME) is a key technology in unmanned aerial vehicle remote sensing (UAVRS). However, when a UAV's motion and behavior change significantly or the image information is not rich, traditional image-based methods for GME often perform poorly. Introducing bottom metadata can improve precision in a large-scale motion condition and reduce(More)
