Database Virtualization: A New Frontier for Database Tuning and Physical Design

Resource virtualization is currently being employed at all levels of the IT infrastructure to improve provisioning and manageability, with the goal of reducing total cost of ownership. This means that database systems will increasingly be run in virtualized environments, inside virtual machines. In this paper, the authors discuss how virtualization...

Learning With Hypergraphs: Clustering, Classification, and Embedding

The authors usually endow the investigated objects with pairwise relationships, which can be illustrated as graphs. Naively squeezing the complex relationships into pairwise ones will inevitably lead to loss of information which can be expected valuable for the learning tasks however. Therefore it considers using hypergraphs in-stead to completely represent...

Interworking of 3G Cellular Networks and Wireless LANs

The third Generation (3G) cellular networks provide ubiquitous connectivity but low data rates, whereas Wireless Local Area Networks WLANs can offer much higher data rates but only cover smaller geographic areas. Their complementary characteristics make the integration of the two networks a promising trend for next-generation wireless networks. With combined...

Powerset's smarts are Microsoft's gain

Larry Dignan pours lukewarm water on Microsoft's acquisition of Powerset. Talking about Google's near monopoly in the search market, Larry says: Microsoft can reinvent search, but it's still running up a natural Google monopoly. The analogy here is Windows: Microsoft didn't have the best operating system on the planet....
