| Abstract | Well logically verified and tested software may fail because of undesired physical phenomena provoking transient faults during its execution. While being the most frequent kind of faults, transient faults are difficult to localize because they have a very short life, but they may cause the failure of software. A fault tolerant method against transient faults under the hypothesis of statically verified software is presented. In order to ensure the right experimental environment, first the specification of the application is validated by Alloy analyzer, second a JML annotated Java code is statically verified. The proposed approach is based on some rules transforming basic Java statements like assignments, conditional and iterative statements into equivalent fault tolerant ones. The current research has exhibited some natural redundancy in any code, and the corrective power of repetitive statements. It also proved that the proposed method makes more efficient fault tolerant versions compared with natural error recovery, i.e. without inserting any additional code for detecting or repairing the damaged state. Illustrated by Gas purification simulator, one can see the natural error recovery in case of fault injection in the code, and how fault tolerant rules recover more errors in less time compared to the natural recovery. The proposed approach is preventive because it avoids the propagation of errors at early stages by repeating low level statements until some “stability” of their behavior. |

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.
