 | Engineers solve a biological mystery and boost artificial intelligence Jan 30th 2013, 13:23 By simulating 25,000 generations of evolution within computers, engineering and robotics researchers have discovered why biological networks tend to be organized as modules -- a finding that will lead to a deeper understanding of the evolution of complexity. The new insight also will help evolve artificial intelligence, so robot brains can acquire the grace and cunning of animals. | | Simulations' Achille's heel Jan 29th 2013, 13:02 What can go wrong when computer simulations are applied outside their original context. In a new article scientists outline the many pitfalls associated with simulation methods such as Monte Carlo algorithms or other commonly used molecular dynamics approaches. | | Streaming video over temporary networks Jan 29th 2013, 12:56 There are extra challenges when accidents occur in hard-to-reach locations such as in a tunnel or impassable mountain terrain where no stable computer networks are found. For the past ten years, however, technology for mobile ad hoc networks that enable rescue workers to communicate with one another or with a command control centre has been available. These networks configure themselves automatically among mobile devices located within a given geographic area. | |
