| Abstract | Failure prognostics is an open research field with options of deeper investigations. Traditionally the applications are statistical methods which do not give accurate results. As the aeronautic systems have become more complex the accuracy of prognosis is already a fact that needs to be considered. Based on the necessity of methods that improve prediction failure time, based-model prognostic failure methods combined with data-model prognostic are receiving more attention than only data-model prognostic. This paper comes from this paradigm, which is based on mathematical modeling building-up a mathematical procedure which results in estimation of a system failure. In order to reach this goal a new definition is proposed, the definition of Failure Severity which estimates the fault evolution until that fault becomes unbearable. So, this paper gives a new methodology that predicts the time to failure before the systems flag it. The results are simulated with prevision for bench-test validation. |

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.
