To satisfy the QoS requirements and improve the reliability of the network, we propose a load-balancing-based fault-tolerant mapping method (LFMM) in smart grid virtual networks. The process of LFMM is divided into two stages, one is node mapping stage, and the other is link mapping stage. During node mapping stage, we present a load-balancing-based virtual node mapping (LVNM) algorithm. We choose...
To segment piecewise smooth images on implicit surfaces, Potts model which is a general variational model for planar multiphase image segmentation is extended to the one for image segmentation on implicit surfaces. Potts model is reformulated not only on implicit closed surfaces but also on implicit open surfaces. An improved dual method is proposed to speed up the computation process. Some numerical...
Analog circuits are regarded as grey system in this paper. The theory of grey system is used to diagnose the fault of analog circuits. Grey relational analysis is used to quantify the relevance between circuit and fault. Analog circuits can be diagnosed by grey relational degree. An example of fault diagnosis is provided in this paper. The result shows that fault diagnosis of analog circuits based...
In medical education, pedagogical agents are widely used by computer learning systems to simulate tutors and/or mimic tutoring interactions, as well as offering just-in-time and adaptive feedback. Although the theoretical aspect of the pedagogical agents has been well-documented in literature, relatively fewer efforts have been made on how a pedagogical agent should be implemented in a real multimedia...
