| Abstract | The IEEE 1451.2 standard introduced the notion of a calibration Transducer Electronic Data Sheet (TEDS), which contains the information needed by software for mapping between transducer-side values and physical unit values. When a calibration TEDS entry is created for a transducer, a calibration model (the degree of the multinomials and the placement of segment boundaries) must be chosen. Calibration TEDS must fit into small memories, and hardware floating point support is typically unavailable for correction function evaluation, but uncertainty due to error fitting the correction function must be minimized. This paper considers the computing of TEDS memory consumption, the number of floating point computations required for each correction, and the uncertainty when the correction function is a spline. It also describes a prototype tool that makes these computations and graphs them in forms intended to be of use in making calibration model design tradeoffs. The tool also contains a facility for automatic selection of "best" designs. |

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.
