| Abstract | We have developed a wide area intruder detection surveillance system which was delivered to the Japanese market last summer. This technology is known as MELWATCH which stands for MELco WATCH(to keep lookout). It has been installed at several sites in Japan. MELWATCH is composed of a pair of sensor cables, a sensor unit and an intrusion detection terminal. The sensor cables are composed of a transmission and a receiving cable (transceiver cables), both of which are off-the-shelf leaky coaxial cables. The sensor cables are deployed in parallel along the boundary to be monitored. Upon activation, the sensor unit sends an electric wave into the transmission cable which results in the electric wave leaks from the cable. The receiving cable receives the leaked electric wave and an electric field is formed between the cables. When an intruder enters the electric field, the sensor unit detects this activity and the precise location of the intrusion. Moreover, this sensor is less affected by the environmental noise, such as trees or small animals, nor weather conditions. In addition, the ability to specify the intrusion point makes it possible to configure the more sophisticated system with pan-tilt-zoom cameras. In this paper, we show the effectiveness of MELWATCH through the field data of the several installed sites. |

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.
