Abstract | Summary form only given. We present a framework for the component-based construction of embedded systems. The framework is based on a general semantic model, encompassing various models of computation for real-time systems. It is characterized by the combined use of models for behavior, interaction and dynamic priorities. Interaction models describe interactions between components by using connectors with synchronization types. Dynamic priorities are used to specify controllers and schedulers in particular. We also present a methodology for model-based composition of real-time systems using this semantic model. The methodology enables correct-by-construction development for properties such as deadlock-freedom and progress, as well as incremental construction and associativity of composition operators. We present two implementations of the framework in system modeling and validation tools developed at Verimag: 1) A partial implementation in the state exploration platform of the IF tool suite dedicated to the validation of asynchronous system modeling languages such as UML and SDL; 2) A more recent full implementation in a platform for the execution of both synchronous and asynchronous components. The methodology is illustrated by the use of these tools on case studies for real-time systems modeling and 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.
