| Abstract | The study of the undersea environment requires the use of scientific instruments at the bottom of the ocean and in the water column to collect useful data. The traditional methods of conducting such studies by sending ships or using bottom instruments and mooring are not able to provide the necessary data over a long period of time due to weather and energy limitations. The objective of the north eastern pacific Time series undersea networked experiment (NEPTUN) program is to construct an underwater cabled observatory on the seafloor of the northeast pacific ocean off the coast of Washington, Oregon, and British Columbia, encompassing the Juan de Fuca tectonic plate. This system features over a few dozens of science nodes for the connection of scientific instruments that enhance our ability to conduct continuous ocean studies in this region. This paper focuses on implementation issue of the NEPTUN power system and compare with Proposal system in Mediterranean. The power system associated with the proposed observatory is unlike conventional terrestrial power system in many ways due to the unique operating conditions of under-water cabled observatories including the high reliability requirements and low operability and controllability. A fault location algorithm is developed to identify a backbone cable fault by solving nonlinear equation with only shore station measurement. The same approach can be applied to underground power system. The results presented in this paper should be applicable to similar underwater system in the future. |

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.
