Mining frequent itemsets is at the core of mining association rules, and is by now quite well
understood algorithmically for main memory databases. In this paper, we investigate …

Both cloud and grid are computing paradigms that manage large sets of distributed
resources, and the scientific community would benefit from their convergence. This paper …

Research in vehicular ad hoc networks (VANETs) has evolved considerably over the last
years. Security and privacy in VANETs have recently appealed special interest in the …

Security is the condition that prevents unauthorized persons from having access to official

Volunteer computing is becoming a new paradigm not only for the computational grid, but
also for institutions using production-level data grids because of the enormous storage …

In the last years several Grid Virtual Organizations-VOs-have been proliferating, each one
usually installing its own Certification Authority and thus giving birth to a large set of different …

The number of Internet connected PCs is projected to reach 1 billion by 2015, which means
