Formulation of efficient algorithms to check implication and satisfibality for relational queries is an important research issue. Implication and satisfibality checking can be used to find query containment in semantic cache query processing and other similar applications. Description logic (DL) is a formalism used to model knowledge of a domain in the form of concepts and a rich set of associations...
Protein and DNA sequences of different organisms are often related and they indicate the knowledge about species. The consideration is made to align more than two sequences so that a level/extend of similarity or differences be found that would help in categorizing the common characteristics of species and their behaviors. An efficient recursive approach is proposed in this paper that would not only...
A data network may not be stable at the connection level under some unfair bandwidth allocation policies, even when the normal offered load condition is satisfied i.e. average traffic load at each link is less than its capacity. In this paper, we present that a data network is stable when the bandwidth of the network is allocated so as to provide a minimum bandwidth using max min fairness algorithm...
Data access latency can be reduced for databases by using caching. Semantic caching enhances the performance of normal caching by locally answering the partially overlapped queries. Query processing (generation of probe and remainder query from the incoming queries) and cache management need to be addressed in its totality to really enjoy these benefits. That is, there is a need of correct, complete...
The importance of the cache is very apparent in the field of computer science. The semantic cache increases its significance by attaching additional meaningful information with the queried data in the cache. XML is used to provide the structure for the data available on the Web. Therefore it is widely used in many organizations for transmitting the data. The structure of XML data files is different...
