| Abstract | Thermodynamic optimization by varying through the use of insulation the heat-transfer rate at finite number of points is studied for one-dimensional heat transfer in systems consisting of different materials in series, whose equivalent conductivity is a function of temperature. For this purpose the results of previous research by the author (Proc. 23rd Intersociety Energy Conversion Conf., p.67-73, 1988), in particular, on the rate of entropy production in regarding one-dimensional heat transfer, are utilized. Four possible cases are considered: (a) shield temperatures are known a prior and the shield positions that minimize the total entropy production rate are required; (b) shield positions are known and the shield temperature are required for which, were these chosen a priori, the shields would be in the most convenient position; (c) shield positions are known and the shield temperatures that minimize the total entropy production rate are required; (d) neither shield temperatures nor shield locations are given and it is required to optimize both simultaneously. It is found that, with certain exceptions, there is almost always one and only one minimum of the total entropy production rate.< |

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.
