Reordering is a major challenge in machine translation (MT) between two languages with significant differences in word order. In this paper, we present an approach to learn reordering rules as pre-processing step based on a dependency parser in phrase-based statistical machine translation (SMT) from Vietnamese to English. Dependency parser and transformation rules are used to reorder the source sentence...
In this paper, a stable leader-following formation control for multiple mobile robot systems with limited sensor information is studied. The proposed algorithm is to control a robot (follower) to follow another robot (leader), and easily extended to form any complex formation. The control algorithm requires information available from onboard sensors only, and utilizes estimation of leader’s acceleration...
In this paper, the leader-waypoint-follower robot formation is constructed based on the relative motion states to form and maintain the formation of multi-robots by stable tracking control method. The main idea of this method is to find a reasonable target velocity and angular velocity to change the robot’s current state. The proposed Lyapunov functions prove that robots change current velocities...
We introduce two enhanced wavelet-based methods to improve accuracy and optimize calculation efficiency for sonar time delay estimation. Existing time delay estimations provide poor results because of many environmental effects such as noise, multipath, and crosstalk. While advanced digital signal processing (DSP) techniques have been proposed to overcome these problems, they entail increased complexity...
