Analyzing Online Social Networks
Social network analysis explains why some sites succeed and others fail, how physical and online social networks differ and are alike, and attempts to predict how they will evolve.
The U.S. patent system is overdue for reform, but what needs fixing, and how, is a matter of some dispute.
User-Centric Services Provisioning in Wireless Environments
To date, services provided for mobile users are still hard to build. Two main challenges need to be considered. The first challenge is about the personalized access to services. The second challenge is about handling limited resources of mobile devices.
A European Perspective of VoIP in Market Competition
The debate on the future of VoIP (Voice Over Internet Protocol) is not new. For some time now this technological innovation has been considered one of main drivers for reshaping the telecommunications industry.

In Search of Dependable Design
How can software and hardware developers increase the reliability of their designs?
As software migrates from local PCs to distant Internet servers, users and developers alike go along for the ride.
Researchers at IBM Almaden Research Center have demonstrated the feasibility of a class of data storage called racetrack memory that combines the data storage of a magnetic hard disk with the speed and strength of flash memory at relatively low cost. Technology Review reports that, unlike flash, racetrack memory would not degrade over time. A […]
