| Abstract | Machinery diagnostic systems detect and monitor faults but are unable to predict remaining life. The RiskMAN/sup TM/ process developed as one of the modules of the Neural Network System Health Usage and Monitoring System (NNS/HUMS), developed under JAHUMS contract administered by NSWC/CD, provides the means for converting the outputs of a diagnostic system into parameters usable in a set of life extension mathematical predictors. Loads and fault severity indicators are incorporated into a risk probability of survival [P/sub s/(t)] equation which varies over time as the machinery loads and faults vary. A measure of the machinery reliability [R(t)] is employed in the derivation of P/sub s/(t) and in modified forms as bases of comparison for P/sub s/(t). The lower confidence limit on R(t) and a safety level R(t) are used in conjunction with P/sub s/(t) to indicate alarm conditions. RiskMAM/sup TM/ techniques and mathematical models have been developed as put of the NNS/HUMS real time diagnostic system for Navy and Army military aircraft (Giuntini, 1997). The NNS/HUMS is a critical link in the transition from a safe life maintenance (SLM) philosophy to a condition-based maintenance (CBM) philosophy. RiskMAN/sup TM/ receives the output parameters from the neural network module which are load state, fault class, fault severity, fault probability and severity probabilities. Then it converts these parameters into meaningful information that will detect an imminent failure or will enable life of the system to be extended beyond its normal/typical overhaul time. Though being developed for military aircraft applications, RiskMAN/sup TM/ is also applicable to general industrial machinery. |

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.
