| Abstract | Abnormal sensor signals may cause missed diagnosis in the fusion fault diagnosis system based on evidence theory. To diagnose the fault in time with abnormal sensor signals, fault-tolerance is required. An evidence redistribution method is proposed for the sensor fault-tolerance of fusion diagnosis system. The evidences directly calculated from sensor characteristic parameters are updated by an evidence redistribution function. Fusion experiments are done on the hardware experimental platform for vibration isolation. The diagnosed fault is vibration divergence. The fusion diagnosis results on the situations of misconnection, disconnection, multichannel abnormity and normal sensor signals are analysed and compared. Experimental results show that the evidence redistribution method can solve the sensor fault-tolerance problem effectively. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
