As XML becomes the de facto standard for data representation and exchange over Internet, there are ever increasing applications using XML as a middleware model. Network-computing paradigm is also changing; it shifts to mobile agent paradigm. Building a mediated query system by combining both XML and mobile agent technologies is very promising. In this(More)
This paper presents a method of fault polygon extraction and smoothing. It uses boundary tracking algorithm to extract breakpoint locations to form polygon file, and uses parameters of angles between fault polygonal lines as well as edge length and so on to do the work of smoothing, on condition that it keeps its original shape. This method improves the(More)
Functional integration is crucial and has become a research interest in recent years; however, available efforts suffer from low efficiency and narrow operating bandwidth. Here, we propose a novel strategy to design bifunctional meta-surface with high efficiency and largely enhanced bandwidth in reflection geometry. For demonstration, we designed and(More)
