| Abstract | At Fraunhofer ISE, a photovoltaic/thermoelectric hybrid system has been developed as a power supply for repeaters (e.g. mobile telephone repeaters) and integrated into a newly constructed repeater station. A modified thermoelectric generator from the Canadian Global Thermoelectric company has been used as the auxiliary generator. A microprocessor-controlled energy management system (EMS) allows fully automatic operation with minimal use of fossil fuels and appropriate battery operation management. As the auxiliary power supply can support the PV generator in supplying power to the load during periods with little sunlight, a very reliable power supply is achieved. Further, the dimensions of the PV generator and the battery capacity can be reduced without affecting the supply reliability. In Central Europe, for instance, the size of the PV generator can be reduced to a third of that needed for an exclusively PV system, if only 10% of the annual demand is met by the auxiliary generator. This allows a compact construction of the photovoltaic hybrid system and helps the numerous requirements on isolated telecommunications facilities to be fulfilled. |

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.
