Found at HPCwire Approximately 800,000 shipments of hazardous materials move daily through the U.S. transportation system and approximately one truck in five on U.S. highways is carrying some form of hazmat. While the safety record is excellent, public sensitivity to the risks associated with hazmat shipments is substantial. …Nozick and Dadkar’s game-theoretic model simulates the […]

But I was intrigued by the idea of a “flash mob” computing event that was organized way back then and discussed last week in this blog post Similar to cloud computing, there is another concept called “Flash Mob Computing”. As […]
