|Description||: This paper presents a new algorithm for simulation of large scale nonlinear systems. The algorithm is a development and generalisation of Kron's ideas on tearing linear systems and it combines Newton-Raphson iterative process with diakoptical calculation of state increments in each iteration. The nonlinear network tearing algorithm has been implemented in 3L Parallel Fortran 77 and run on a 5 transputer system hosted in a Unix workstation. Computational results, obtained for a realistic nonlinear system, are provided and discussed. 1. INTRODUCTION Decomposition can provide a useful basis for the optimisation or control of many large scale systems. Physical structure of the problem often facilitates its partitioning into a number of smaller subproblems which can be solved individually, and the results recombined to achieve the solution of the overall problem. To take into account interactions between the subproblems, the overall solution proceeds as a sequence of subproblem solution...|

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.
