However, extracting generic bases requires partially ordering costly computed itemset closures. To avoid the nightmarish itemset closure computation cost, specially for sparse contexts, we introduce an algorithm, called Prince, allowing an astute ext...

Avoiding Overload by Using Virtual Machine in Cloud Data Centre
Cloud data centres improve CPU utilization of their servers (physical machines or PMs) through Virtualization (virtual machines or VMs). Over virtualized and under virtualized PMs suffer performance degradation and power dissipation respectively. In this paper, system that uses virtualization technology to allocate data center resources dynamically based on application demands and support green...
