With more and more large networks becoming available, mining and querying such networks are increasingly important tasks which are not being supported by database models and query...
Data lineage and data provenance are key to the management of scientific data. Not knowing the exact provenance and processing pipeline used to produce a derived data set often re...
A fundamental problem that confronts future applications of sensor networks is how to efficiently locate the sensor node that stores a particular data item. It is known that distr...
Applications that query into very large multidimensional datasets are becoming more common. Many self-describing scientific data file formats have also emerged, which have structu...
We present results related to satisfying shortest path queries on a planar graph stored in external memory. Let N denote the number of vertices in the graph and let sort(N) denote...
