| Abstract | The TPR-tree is a popular index structure utilized to query the present or future positions of moving objects. Compared with the traditional spatial index structures, the TPR-tree is more appropriate to satisfy the requirements of storage and queries of moving objects. However, when a TPR-tree is constructed, the velocity difference of moving objects in the same direction hasn’t been considered. This will cause numerous invalid regions with lower efficiency for query execution. To solve this problem, we present an enhanced spatio-temporal index structure: VCTPR-tree, and it can avoid invalid regions by introducing velocity to change the time stamps thus improve the query performance. |

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.
