This paper investigates the trajectory tracking control of the nonholonomic wheeled mobile robot (NWMR) using nonlinear model predictive control (NMPC). By defining the tracking error in the NWMR's local coordinate, the tracking problem is formulated into standard NMPC framework. However, the standard NMPC algorithm is computationally demanding so that it is difficult for the real-time implementation...
C-means clustering algorithms have proven effective for image segmentation, but are limited by the following aspects: 1) the determination of a priori number of clusters. If the number of clusters can be incorrectly determined, a good-quality segmented image cannot be assured; 2) the poor real-time performances due to great time-consuming, and 3) the poor typicality of each cluster represented by...
Vehicle-to-vehicle communication and probabilistic broadcast are important means for information dissemination in vehicular ad-hoc networks (VANETs). In contrast to static ad-hoc networks, high-speed mobility makes wireless connection between two vehicles intermittent. Nevertheless, some kinds of information do not rely on continuous connection for transmission. An important fact is that numerous...
According to the current research of time synchronization for wireless sensor networks, we class the emerging synchronization algorithms. And mathematical application in the synchronization algorithm for wireless sensor networks is analyzed in depth. Basing on those, this paper presents some new view for the future research of synchronization algorithm.
