Three representative types of double semitrailer road train are put forward based on analyzing the application in developed regions such as Europe and U.S.A. Using Auto TURN, vehicle turning clearance circle test simulation models of double semitrailer road trains are established according to GB 1589. The simulation models are used for analysis passing ability according to the requirement of China...
Power system short-term load forecasting have a significant role in the power system planning and reliable operation. This paper compared the result of two prediction models BP neural network and wavelet neural network (WNN). According to comparison results, WNN model in the case of the same number of nodes have better predictive accuracy. In order to achieve the balance of the least input neurons...
The paper focuses on the data warehouse, OLAP and data mining technology, and discusses a variety of modeling methods. Combining with Unicom specific applications, starting from market development and analysis of the valuable users, the paper realizes flexible marketing strategy, as well as makes their own resources allocation rationalization and optimization, so as to reduce operation costs.
