Hyphantria cunea is one of the harmful international plant quarantine pests. In order to monitor and control the increasingly serious situation, based on the materials and data collected by “the 221 project” in Beijing in recent three years, this paper studies the spatial decision-making system of hyphantria prevention and control simulation, by combining WebGIS, JSP and Ajax technology. We design...
The difficult issue of Web data mining is proposed to achieve Web data mining method, which is based on XML-based Web database in the face of semi-structured data structure excavation process, the data feature extraction process, we found the hidden rules and knowledge, the method is simple, effective and low cost. The paper first gives the definition of data mining; describes the process and commonly...
In order to realization electronic parts product appearance quality detection control, one kind of processor based on the intelligent knowledge automatic extraction and system intelligence modeling was presented. In the processor, wavelet-fuzzy technique and neural network technique are combined. Uses the fuzzy wavelet extraction image feature, and wavelet function is used as fuzzy membership function...
