Three join algorithms are evaluated in an environment with distributed main-memory based mediators and data sources. A streamed ship-out join ships bulks of tuples to a mediator ne...
The wavelet decomposition is a proven tool for constructing concise synopses of massive data sets and rapid changing data streams, which can be used to obtain fast approximate, wit...
Multimedia Database Management Systems (MMDBMS) have to efficiently provide the specific functionalities required by time-dependent multimedia data types. During presentation play...
Resource sharing can cause unfair and unpredictable performance of concurrently executing applications in Chip-Multiprocessors (CMP). The shared last-level cache is one of the mos...
We introduce a new primitive called Intrusion-Resilient Secret Sharing (IRSS), whose security proof exploits the fact that there exist functions which can be efficiently computed ...
