Geographic Information Systems (GIS) are increasingly managing very large sets of data and hence a centralized data repository may not always provide the most scalable solution. H...
Wireless sensor networks offer the potential to span and monitor large geographical areas inexpensively. Sensors, however, have significant power constraint (battery life), makin...
The Relational On-Line Analytical Processing (ROLAP) is emerging as thedominant approach in data warehousing with decision support applications. In order to enhance query performa...
In the experiment described in this paper, we investigate the effectiveness of a document-independent technique for eliciting additional information from searchers about their inf...
The data cube operator exemplifies two of the most important aspects of OLAP queries: aggregation and dimension hierarchies. In earlier work we presented Dwarf, a highly compress...
