A great challenge in securing sensor networks is that sensor nodes can be physically compromised. Once a node is compromised, attackers can retrieve secret information (e.g. keys)...
Clusters are now composed of non-uniform nodes with different CPUs, disks or network cards so that customers can adapt the cluster configuration to the changing technologies and t...

Document retrieval and web search engines index large quantities of text. The static costs associated with storing the index can be traded against dynamic costs associated with us...
Bitmap indexes are widely used in Decision Support Systems (DSSs) to improve query performance. In this paper, we evaluate the use of compressed inverted indexes with adapted quer...
Well-designed indices can dramatically improve query performance. Including query workload information can produce indices that yield better overall throughput while balancing the...
