This paper presents a novel technique for efficient evaluation of magnetic resonance imaging (MRI)-induced electric fields or induced voltages in the vicinity of implanted metallic leads. The technique is based on the reciprocity theorem in conjunction with the Huygens Principle. This approach allows one to decouple the micro-scale metallic lead simulation/measurement from the macro-level phantom...
Nowadays, the micro blog has become one of the main platforms for information dissemination. Because the micro blog has massive users and the information is propagating in real time, the traditional information diffusion models are difficult to characterize the influence of the micro blog as a social network of communication. In this paper, two influence propagation models, namely the basic model...
This paper presents a novel technique for the efficient evaluation of MRI-induced electric fields in the vicinity of implantable metallic leads. The technique is based on the reciprocity theorem in conjuncture with the Huygens principle that allows one to separate the micro-scale modeling of the metallic lead from the macro-level modeling of human subjects within MRI scanners. In addition to the numerical...
Although many projects, especially grid workflow projects, are trying to make grid application development easier and quicker, the process-based application description model adopted by most of the grid-enabled applications still bothers scientists who are the main users of grid and usually beginner in programming. In this paper, a data dependency based application description model, which describes...
The difficulty of grid-enabled application development is one of the obstacles to employ grid as infrastructure of scientific computing. Although there are many projects, especially grid workflow projects, trying to make grid-enabled application development easier and quicker, the process-based application description model adopted by most of the grid-enabled applications still bothers scientists...
This paper analyzes the characteristics of parallel algorithm for Image and real-time processing of image which base on the cluster-computer. An improved double-sync(the bulk synchronous and the cycle of synchronization) BSP model is proposed, which provides the capability of the real-time processing. Under the clustered computer system, we adopt the leaping task allocation algorithm and the method...
