Multi agent system (MAS) reputation has some shortcoming in the existing model, such as system dynamic analysis and storage capacity. Based on dynamic analysis of MAS trusting model and its problems on system storage, this paper proposes a new trust mechanism which uses combined dynamic time to modify the weight of time. To mimic the dynamic ability of MAS system, we introduce a new parameter of dynamic...
With LiOHldrH2O and NH4VO3 as the identical starting materials, several diverse methods were introduced to prepare lithiated vanadium oxides LiV3O8 which are promising as the cathode material for secondary lithium batteries. The crystalline phase were characterised by powder X-ray diffraction. The electrochemical properties of prepared samples were systematically investigated and compared. The maximal...
To solve the problem of mining weighted frequent traversal patterns (WFTPs) with noisy weight information from weighted directed graph (WDG), an effective algorithm called SWFTPMiner (statistical theory-based weighted frequent traversal patterns miner) is developed. It first adopts statistical notion called confidence interval (CI) to delete the vertices with noisy weights from the traversal database...
Identifying gene names in biomedical texts is regarded as a crucial step for text mining. Our approach is a combination of dictionary based approach and machine learning based approach. Based on a gene name dictionary, an edit distance approximate string searching algorithm was used to improve the recall rate of gene recognition which is greatly lowered due to a lack of standard gene-naming conventions...
