With the rapid development of Internet technology, information resources on the Internet become more abundant, but also bring some problems like diversity, heterogeneity, disorder, and redundancy. Given a brief expression like search keywords only, users' needs are ambiguous. Therefore, current technologies of search applications relying on direct keyword matching cannot meet the requirements of users...
Based on the theory of vector control of the induction motor, a new method for modeling and simulation of induction motor field orientation based on LabVIEW is proposed. This paper discusses the calculation of the flux position, the realization of the SVPWM, the equivalent transformation. The reasonability and validity are verified by the simulation and experimentation. This method offers a new thinking...
In this paper we develop a theoretical model for the relationship among environmental dynamism, social network and resource development of new firms. Resource development includes resource acquisition and resource integrating. We analyze the effect of network size and network intensity on resource acquisition and resource integrating. We also analyze the effect of environment dynamism on the characteristics...
Data mining has become increasingly critical for the success of companies in this emerging era of engineering management. As engineering management activities increasingly shift to the Web, the challenge facing corporate management is maintaining competitive advantage by building strong relations with employees, customers, and suppliers and partners. A good data mining strategy can help achieve this...
Formal verification of low-level programs often require explicit reasoning and specification of runtime stacks. Treating stacks naively as parts of ordinary heaps can lead to very complex specifications and make proof construction more difficult. In this paper, we develop a new logic system based on the idea of memory adjacency from stack typing. It is a variant of bunched logic, and can be easily...
In order to improve the reality, useful and whole performance of network intrusion detection system (IDS), the solution to get independent features used to (or evidence) IDS is presented in the paper. The approach of auto-recognition of inter-relativity of the features is developed, which is classification method for features. The features picked up by the method are used as the input of back propagate...
