In view of the problem that it is difficult to predict the output in an oilfield which affected by multiple variables, a back propagation (BP) neural network model is built to predict the output in oilfield because the classic statistical method and static model can not meet the demand of precision for the nonlinear and uncertain system. Effective depth, permeability, porosity and water content are used as the input of neural network and oilfield output as the output of the neural network. The results show that this prediction approach is very effective and has higher accuracy. The results show that the model can forecast the oilfield output with accuracy comparable to other classic methods. So the BP neural network is an effective method to predict the oilfield output with high accuracy. The application of this approach can supply reliable data for the development of oilfield and decrease the risks for the exploitation.

the rapid development of data technology, as exemplified by data mining and Internet growth, creates a large information overload and forthcoming knowledge overload. Data mining discovers a large mount of knowledge, but not all of the knowledge is useful. Meanwhile the useful knowledge will also become un-useful as time goes by. How to manage this kind of knowledge is an urgent problem for data mining applications. A new research field called Intelligent knowledge (IK) is put forward and we try to explain the needs for coining the term as a sub-discipline of BI for systematic studies on knowledge application related theories, as well as the design of Intelligent Knowledge Management Systems (IKMS). Main topics are discussed to demonstrate why we consider IK to be a subject worthy of study and, at the same time, to establish a starting point for the further research.

Steering-by-Wire system has received lot of attention in the recent years because of the development of vehicle stability control systems and intelligent vehicle highway systems. The variable structure controller based on the reference model with a drive model is insensitive to parameter variations so that the available control authority and the effect of Steering-by-Wire system on vehicle yaw response and side slip response is estimated using computer simulations. The results of simulink demonstrate the benefits of the proposed control method in terms of improved vehicle responses and reduced driver steering effort.

In designing low power switching mode power supply (SMPS), its functions, tech-parameter and cost should be considered at the same time. TOP Switch has stronger functions than the discrete components. It is easy and flexible to design SMPS based on TOP Switch and the products always get less cost. SMPS based on UC3842 or UC3843 is compared with the one based on TOP Switch in the paper. Then an actual project used fly-back converter is put forward.

During last few years, a number of kernel-based online algorithms have been developed that have shown better performance on a number of tasks. A well designed online algorithm needs less computation to reach the same test accuracy as the corresponding batch algorithm. In this paper, we devise an online training algorithm for L2-SVM. Our work is motivated by HULLER, an online algorithm proposed by A. Bordes and L. Bottou. The proposed algorithm implements two speedups with respect to HULLER, first it chooses an old example for removal based on sound computation instead of random selection; second it uses more effective update rule. Experiments on benchmark data sets show the merits of our method.

For parallel operation of electric network it need to control the current to be in phase with the electric network voltage. This paper presents a control method of phase tracking based on artificial neural network. After comparing the simulation results between BP network and RBF network, it takes the algorithm of RBF network into Phase Locked Loop. It takes the electric network voltage as the expected output and current as training sample. Then through the self-learning of neural network it can gradually reduce the error of output between the sample and the expected target, and achieve the the synchronization and tracking of the expected output. In this paper it has been carried out through digital dynamic simulation using the MATLAB Simulink Power System Toolbox. The results of simulation shows that it can track its target well and have strong adaptive capacity.

Business process model and data model play important roles in information system construction. They represent two different perspectives of business knowledge, and are closely related. A trouble to the model quality is the inconsistency between business process model and data model, which can often conduce to interaction errors. While finding such inconsistency is a meaningful problem, it receives little attention in available verification methods. We concentrate on this problem and identify some consistency anomalies between process model and data model. In our paper, a verification method PDGV is proposed to verify the consistency between process model and data model. Implemented prototype reveals that our scheme can detect consistency anomalies effectively.
