| Abstract | Ahlswede has previously introduced an abstract correlated source (/spl Vscr//spl times//spl Wscr/,S) with outputs (/spl upsi/, /spl omega/)/spl isin/S/spl sub//spl Vscr//spl times//spl Wscr/, where persons P/sub /spl Vscr// and P/sub /spl Wscr// observe /spl upsi/ and /spl omega/, respectively. More recently, Orlitsky considered the minimal number C/sub m/ of bits to be transmitted in m rounds to "inform P/sub /spl Wscr// about /spl upsi/ over one channel." He showed that C/sub 2//spl les/4C/sub /spl infin//+3 and that in general C/sub 2/NOT/spl sim/C/sub /spl infin//. We give a simple example for C/sub 3/NOT/spl sim/C/sub /spl infin//. However, for the new model "inform P/sub /spl Wscr// over two channels", four rounds are optimal for this example-a result we conjecture in general. If both P/sub /spl Vscr// and P/sub /spl Wscr// are to be informed over two channels about the other outcome, we determine asymptotically the complexities for all sources. In our last model "inform P/sub /spl Vscr// and P/sub /spl Wscr// over one channel" for all sources the total number T/sub 2/ of required bits is known asymptotically and T/sub /spl infin// is bounded from below in terms of average degrees. There are exact results for several classes of regular sources. An attempt is made to discuss the methods of the subject systematically. |

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.
