| Abstract | The current state of the art in electronic prognostic health management systems does not fully support detection, collection, and remediation of real-time faults. As a result, knowledge has not been captured from an actual platform failure mechanism. Thus, point-of-failure feedback cannot be applied by system designers or operators to improve lifecycle weak links in replacement platforms, or to strengthen effectiveness of mission-critical platforms. Our innovation makes it possible to extract and analyze the power system's eigenvalues, which are related to the intrinsic frequencies of the power system that determine correlations between extracted features and state of health (SoH). In-situ electronic prognostics for power systems are crucial for attaining a sound theoretical basis of health status. To provide correlation information such as state of health (SOH) using pattern analysis with real-time data from a non-intrusive smart power sensor, Ridgetop researched using data-driven modeling with a proposed health distance and Support Vector Machines (SVMs) with signatures in a standard IEEE 1451-enabled smart power sensor. Results of this study indicate that a fault pattern analysis methodology overcomes certain disadvantages of the standard failure modes and effects analysis (FMEA) approach, which does not account for the contribution of unobserved failure to a degradation trajectory. The efficacy of the proposed pattern analysis approach is illustrated with test results showing critical distinction in pattern analysis and test data acquired from a real-time IEEE 1451-enabled smart power sensor testbed, and monitored via a testbed with appropriate instrumentation. 1 2 |

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.
