| Abstract | Ultra-reliability means assured, dependable operation over the required service life with repeatable success. This will be a vital part of any system developed for the NASA space exploration vision. In order to achieve this goal, equipment must be able to survive the stresses of prolonged operation and there has to be a drastic reduction in manufacturing flaws and the human error rate. There will have to be a dedication to the practice of designing in highly robust electrical, mechanical, and electromechanical components into complex systems and special attention to survival of environmental threats such as radiation and micro-meteors. Complex systems present an exceptional challenge because of the large number of potential failure modes as well as the possibilities for system interactions and failure propagation. Failure mode and effects analysis, Event Tree, and fault tree analysis should be applied to the hardware and software as an integrated configuration. In many cases, it will be determined that existing technology has reached its reliability or operating life limit and new technology will be required. Sustained research and development over a period of 20 years or beyond may be needed to develop Ultra-reliable systems on a mass scale. New technology with greater operating life may be able to support the goal of ultra-reliability but that new technology also introduces new reliability problems that will have to be overcome. Resources and established practices for reliability engineering must be strongly maintained as the foundation for achieving ultra-reliability. |

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.
