| Abstract | STAR-Light is a 10 element, 1.4 GHz aperture synthesis radiometer being developed at the University of Michigan. It features 3 new technologies: 1) 2-dimensional aperture synthesis using 3-bit correlation, 2) Direct Sampling Digital Receiver (DSDR) architecture, and 3) band definition in the digital definition in the digital domain. The instrument successfully completed Critical Design Review in the spring of 2002 and is being fabricated as funds become available. As a test of robustness of the receiver design, we are using four STAR-Light receivers in a dual-polarized 1.4 GHz radiometer, and two are used as IF amplifiers in a dual-polarized 6.7 GHz radiometer. Both radiometers will eventually be fully polarimetric. The system is currently deployed near Fraser, Colorado, as part of the NASA Cold Lands Processes Experiment (CLPX) to occur in February and April, 2003. We will report on the performance of these receivers in this relatively harsh environment. |

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.
