Contactless power transmission system can supply power in non-contact way for many electronic equipments, it has become a hot topic in recent research. Take topological structure of serial-parallel CPT system for example, the optimal values of the compensation capacitors which can solve the poor coupling problem of the separable transformer are determined. A frequency tracking control system based...
In order to predict the dynamic surface subsidence and deformation, a working face was divided into some mining elements along strike according to the face advancing, and the dynamic surface subsidence and deformation was regard as the superposition of the dynamic subsidence and deformation independently of all these mining elements. There might be a section of which width was shorter than a mining...
In recent years, there has been an increasing interest in data clustering of short documents. Existing works consider seldom the concept similarity between the words, so the quality of clustering is often very low. This paper proposes a new document-clustering algorithm based on concept similarity in Chinese text processing. Different from tradition method, the algorithm converts text into a words...
