| Abstract | Summary form only given, as follows. The transient sheath expansion induced by a voltage pulse applied to two-dimensional targets is simulated numerically with a fluid model. Non-linear sheath expansion due to sheath overlapping in a small cylindrical bore with a finite depth is presented. The sheath expansion inside the bore is enhanced by the initially nonuniform plasma distribution. The angular distribution of the ions impinging on the target surface and the nonuniformity of the incident ion dose are calculated for a cylindrical bore target. A dip of the dose profile, seen earlier for square targets, appears at convex corners of the target. This dip is a numerical artifact, not a real physical phenomenon, mainly caused by false diffusion (numerical diffusion) and inaccurate estimation of the electric field on the corner. By re-orientation of the numerical mesh to suppress false diffusion, the dip effect can be be eliminated effectively in the square target case. |

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.
