| Abstract | The author develops a model to estimate the average number of repair actions (RA) for a system that is divided into two parts: the functional circuits that execute the operations required by the objectives of the system, and a part that performs error detection and diagnostic functions. The breakdown of a functional circuit (FC) generates a repair action but the failure of a maintenance circuit (MC) is only observable through FC failures. On the other hand, MC breakdowns may cause an incorrect diagnosis or fault isolation, and several repair actions may therefore be required to restore the operation of the system. The failures of the circuits come from either defective chips that have not been detected during manufacturing and testing or time-dependent breakdowns of the circuits that occur after the installation of the system. The author shows that similar formulas can be used in both estimations. The expected number of defective (failed) functional chips is inflated by the probability that there might be defective (failed) maintenance circuits in the system. |

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.
