How Smart is the Grid?

François Maréchal, Luc Girardin, Ermanno Lo Cascio, Zhichuan Ma

Ancient Romans called urbs the set of buildings and infrastructures, and civitas the Roman citizens. Today instead, while the society is surfing the digital tsunami, urbs and civitas tend to become much closer, almost merging, that we might attempt to cond ...
