| Abstract | Electrical impedance tomography (EIT) attempts to reconstruct the internal impedance distribution in a medium according to electrical measurements with electrodes on the medium surface. Main problem of EIT is the drift of electrodes during the medical applications, in which the body surface moves during breathing and posture change. In this paper, a new approach which can distinguish electrode movements from measurement data of EIT for eliminating such effects in static reconstructed image is presented. To achieve these objectives, this paper proposed a linear model to describe affection of boundary voltages caused by electrode movements. A genetic algorithm for the problems is introduced, which attempted to find the optimization of electrode movements to match the measurement voltages. To get least number of iterations possible, we introduce cultivation process in mutation operator. Simulation experiments show that the genetic algorithm is efficient and effective for electrode movement problem. |

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.
