Data mining is used to analysis a large number of data. The study was using asset management of freeway flexible pavement and re-dug out new knowledge of pavement cracks by using decision tree of data mining. Road units were built per 20 meters per lane. Construction data (35,828 documents) was built and included road construction type, altitude and topography. Maintenance constructions data (36,439...
The Examination of broiler price periods is very important in forecasting broiler price for the poultry breeding industry because it is beneficial to maximizing the profit and minimizing the risk. As wavelet transforms are well known to work well for reducing the noise of the data, in this paper we perform wavelet transforms and pork prices to de-noise the broiler prices, and then apply variance analysis...
The massive primary data can be obtained through the electromagnetic environment monitoring. How to fuse these data with other new technologies and carry on the deeper data mining is the focus of this article. The trend surface analysis, the radiation source's localization as well as the electromagnetic environment evaluation have been discussed.
This paper developed a real-time signal timing model which was to be integrated into multi-intersection in urban area, to some extent, relieving the traffic congestion. We firstly analyzed the current traffic flow by using release matrix at a single intersection and multi-intersection respectively. Integrated with the optimal Webster split algorithm, the optimal real-time signal timing model, which...
In the remote sensing data processing the key in extracting thematic information is to compartmentalize the background and the anomaly. Anciently we use the singleness threshold parameter to extract the anomaly information in the same area. Actually different landscape area have different thematic information background, namely it have background spatial differentiation characteristic. So when we...
In the generating system of electromagnetic mesh, the most crucial technique is to generate the effective and exact mesh. With the AutoCAD as the graphics support platform, this thesis develops software of auto dissection with three-dimensional mesh for the finite-difference time-domain electromagnetic simulation, applying ObjectARX of AutoCAD, combined with the graphic file of AutoCAD. The method...
With the continuous advances in communications technology, the link transmission speed of the Internet backbone networks has been increasing rapidly. This in turn demands more powerful IP address lookup engines. Being well-suited for high performance parallel lookup, Ternary Content Addressable Memory (TCAM) has been widely used in this area for years. Nevertheless, the limited storage, high power...
