The ever-increasing quantities of digital photo resources are annotated with enriching vocabularies to form semantic annotations. Photo-sharing social networks have boosted the need for efficient and intuitive querying to respond to user requirements in large-scale image collections. In order to help users formulate efficient and effective image retrieval,(More)
In many applications such as sensor networks, similarity search is more practical than exact match in stream processing, where both the queries and the data items are always change over time. The volumes of multi-streams could be very large, since new items are continuously appended. The main idea is to build a small size of synopsis instead of keeping(More)
Actually, large database is not simply considered as a stream database because of streaming data is not only containing huge data volumes, but distributed, continuous, rapid, time varying. Therefore, the general techniques may not suit for streams exactly. Accuracy responses required of approximated answers is more important in stream processing for the(More)
(Sn, Fe)-codoped In2O3 epitaxial films were deposited on (111)-oriented Y-stabilized ZrO2 substrates by pulsed laser deposition with constant Fe concentration and different Sn concentrations. The influence of Sn concentration on the crystal structure and properties of Fe-doped In2O3 ferromagnetic semiconductor films has been investigated systematically.(More)
In many real-world applications, data streams are usually collected in a decentralized manner such like sensor network, ubiquities sensor network, internet traffic analysis, and so on. In particularly, requirements for continuous, fast, high-volumes, adaptability, costly streaming data, an approximated analysis is needful for fast response to users on(More)
