Active Distribution Network (ADN) implements the operation and consumption of distributed energy resources (DERs), especially in the use of renewable ones, by hierarchical and distributed coordination control mode. Plenty of advanced communication and control technologies must be integrated in ADN. In this paper, a new method of co-simulation for ADN is proposed based on Ptolemy II and Simulink. In...
This paper addresses a perimeter patrol problem involving control of unmanned air vehicles. Around the perimeter of a protected area are placed a number of unmanned ground stations. These stations send alert signals which are investigated by the unmanned air vehicles. We present an approach to optimization of vehicle tasking based on max-plus probabilistic models and computational schemes.
For a wireless sensor network (WSN) to operate successfully in an application of detecting a mobile intruder, the sensor's sensing of the intruder and the communication between the tasking sensor(s) and the base station should be jointly considered for effective intrusion detection. Most related work either treats the two tasks separately or considers both tasks for general-purpose WSN applications...
In the scheme of Pawlak rough derivatives theory, functional features of roughly derived functions and higher order roughly derived functions are directed in rough function model. The valuing laws of first order and higher order roughly derived functions are given in form of a rough derivatives table. According to the difference principle of numerical analysis theory, the higher order rough derivative...
The incompleteness and insufficiency in the investigation of rough continuity in Pawlak rough function model are pointed out. Proposing the e-d definition of rough continuity of a discrete function, the concept of Pawlak rough continuity is deduced in the form of a proposition. A series of operating properties of roughly continuous functions are discussed such as maximization, minimization, complementarity,...
Video content summarization provides an effective way to accelerating video browsing and retrieval. In this paper, we propose a novel approach to automatically generate the video summary. Firstly, the video structure is analyzed by spatio-temporal analysis. Then, we detect video non-trivial repeating patterns to remove the visual-content redundancy among video stream. Moreover, an importance evaluation...
