As a kind of soft actuation materials, Ionic polymer-metal composites (IPMCs), displaying an excellent capability of converting electrical energy to mechanical energy, are promising applications in robotics and medical devices. In this paper, we introduce a millimeter thickness IPMC actuator with a new patterned configuration. Firstly, a perfluorinated ion exchange membrane with millimeter thickness...
This paper presents a new approach to generate inequalities invariants of hybrid system based on template and quantifier elimination. The main idea is to introduce a candidate parametric invariant as template and then reduce the verification condition into a quantifier elimination problem. The challenge is to deal with the continuous consecution condition of hybrid system because of the existence...
Two implication operators on interval sets are discussed, related structure theorems are proved. As a generalization of these results, two implication operators on rough sets are established. Moreover, a characterization of HW-algebra is proposed and a mistake in a paper is pointed out.
The Real Time Kinematics Global Positioning System (RTK-GPS) has been proved to be a feasible tool for structure health monitoring. However, there are some limitations using the traditional RTK method under the long baseline conditions, and annoying ionospheric delay.To eliminate this delay, in this paper we present an improved Extended Kalman Filter with Triple-Differenced Ionospheric-Free (EKF-TDIF)...
