This paper examines the tracking property of nonlinear delayed multi-agent systems with impulsive effects. The strengths and locations of the stabilizing impulses, as well as the number of the controlled nodes are all assumed to be time-varying. Some sufficient criteria are established such that the considered system can exponentially track the dynamical reference state based on the given impulsive...
In this paper, we study a simple hyper-heuristic that functions by sampling solution chains. A solution chain in this algorithm is formed by successively applying a randomly chosen heuristic to the previous solution to generate the next solution. Operating in this way, the algorithm can benefit from the accumulated effect of applying multiple heuristics. A key factor in this algorithm is the strategy...
This paper describes a fuzzy control methodology for continuous passive motion equipment (CPM). The methodology combines fields such as artificial intelligence, through the fuzzy controller development; and control engineering, joining an optimization mechanism of movement with closed loop control. Following UML-MARTE profile is used to modeling the methodology. Based on system input/output and a...
An important problem in human-robot interaction is for a human to be able to tell the robot go to a particular location with instructions on how to get there or what to avoid on the way. This paper provides a solution to problems where the human wants the robot not only to optimize some objective but also to honor “soft” or “hard” topological constraints, i.e. “go quickly from A to B while avoiding...
In order to achieve the expected goal accurately, detecting of road region and obstacle, self-organization and planning autonomously and dynamical avoidance are key technologies during the course. For improvement of dynamic obstacle avoidance of autonomous mobile robots, a kind of real-time avoiding-obstacle algorithm via binocular stereovision is addressed, it takes advantage of visual principle...
In this paper improvements to a previous work are presented. Removing the redundant artifacts in the fingerprint mask is introduced enhancing the final result. The proposed method is entirely adaptive process adjusting to each fingerprint without any further supervision of the user. Hence, the algorithm is insensitive to the characteristics of the fingerprint sensor and the various physical appearances...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
