We examine index compression techniques for schemaindependent inverted files used in text retrieval systems. Schema-independent inverted files contain full positional information for all index terms and allow the structural unit of retrieval to be specified dynamically at query time, rather than statically during index construction. Schemaindependent indices have different characteristics than ...

The dried fruit of Terminalia chebula is widely used for its laxative properties. The objective of the present study was to examine the flowability and compressibility of Terminalia chebula fruit powder, subsequently developing its tablet formulations by utilizing wet granulation and direct compression technology. Initial studies on flowability and compressibility revealed that the fruit powder...

Directly embedding the secret data into the VQ-compressed domain is practical for reducing storage and transmittal bandwidth. Many steganography techniques are currently exploited for the VQ index table. However, embedding strategies extend the amount of compression needed for embedding secret data and distort the original quality of the VQ decompressed image. To satisfy the essentials of incre...

In a memoryless vector quantization system, each image block is independently encoded as a corresponding index and then an index table will be generated. In this paper, we propose two novel schemes to compress the index table without introducing extra encoding distortion. Both our schemes exploit the characteristic that the blocks of images are highly correlated to find the same or similar inde...

Information retrieval is the selection of documents relevant to a query. Inverted index is the conventional way to store the index of the collection. Because of the large amounts of data, compression techniques are commonly used in information retrieval systems to reduce the size of the inverted index. We experimentally evaluate the result of the mapping of such techniques on the Compressed Spa...

CyberCity facilitates the processes of urban planning, communication system design, control and decision making, tourism, etc. However, the high efficient database management has become a bottleneck of CyberCity applications. This paper proposes an efficient approach to manage the integrated databases of large CyberCity. This approach consists of following three schemes: At first, a special R+_...
