Attribute reduction is an important research area of rough set theory. Based on rough set theory, this paper established the granular matrix with the idea of granular computing, proposed and defined the AND operation of granular computing, established the knowledge granulation method based on granular matrix, and puts forward the attribute reduction algorithm based on granular matrix. The attribute...
Based on the analysis of current component retrieval methods in web service, a method of retrieving software components based on domain ontology and user interest was studied and implemented. This paper emphasized the definition of ontology feature domain model, the presentation of component description model based on ontology feature and the retrieval method of user interest. Based on these, it presented...
An intelligentized, comprehensive and high efficiency test system of solenoid valve for oil medium is designed in this paper, aiming to the disadvantage of current test devices in most solenoid valve factories in China. Serial communication of OPC-SERVER, sequential control of PLC, frequency conversion speed regulation technology and data acquisitions by LabVIEW are all achieved in this system; modeling...
