| Abstract | Traditionally, condition-based monitoring techniques have been used to diagnose failure in rotary machinery by application of low-level signal processing and trend analysis techniques. Such techniques consider small windows of data from large data sets to give preliminary information of developing fault(s) or failure precursor(s). However, these techniques only provide information of a minute portion of a large data set, which limits the accuracy of predicting the remaining useful life of the system. Diagnosis and prognosis (DAP) techniques should be able to identify the origin of the fault(s), estimate the rate of its progression and determine the remaining useful life of the system. This research demonstrates the use of data mining and numerical visualization techniques for diagnosis and prognosis of bearing vibration data. By using these techniques a comprehensive understanding of large vibration data sets can be attained. This approach uses intelligent agents to isolate particular bearing vibration characteristics using statistical analysis and signal processing for data compression. The results of the compressed data can be visualized in 3-D plots and used to track the origination and evolution of failure in the bearing vibration data. The Bearing Test Bed is used for applying measurable static and dynamic stresses on the bearing and collecting vibration signatures from the stressed bearings. |

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.
