| Abstract | A novel prototype electrical impedance tomography (EIT) system, which uses single-ended signalling, is presented. The single-ended electrical impedance tomography system consists of a host computer, data acquisition system, switching box, MATLAB, and LabVIEW program. Ability of the system to detect and track hidden conductive and non-conductive objects was examined using a beaker (cylindrical shape) of 180 mm diameter and 280 mm height, filled with 3000 mL tap water, and with 16 electrodes attached. Stainless steel and Teflon rods with different sizes were placed in different locations inside the beaker, and images were obtained. All the objects were tested under multiple signal injection frequencies in the range of 12–1000 kHz. The results showed that the system could detect and track conductive and non-conductive objects during certain injection frequencies. The single-ended EIT system requires one wire connection to make one signal injection or measurement, and this is controlled using a multiplexer or switching box. Alternatively, an ordinary EIT system requires additional wire connections for single data measurement or injection, and a more complex circuit to control the I/O signals. This greater number of wires and increased circuit complexity will increase the data error rate and the cost significantly. |

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.
