Inferring individual rules from collective behavior - 2 views

  •  
    "We fit data to zonal interaction models and characterize which individual interaction forces suffice to explain observed spatial patterns."

    You can get the paper from the first author's website: http://people.stfx.ca/rlukeman/research.htm

    PNAS?
    Didnt strike me as sth very new though...
    We should refer to it in the roots study though:
    "Social organisms form striking aggregation patterns, displaying cohesion, polarization, and collective intelligence. Determining how they do so in nature is challenging; a plethora of simulation studies displaying life-like swarm behavior lack rigorous comparison with actual data because collecting field data of sufficient quality has been a bottleneck."
    For roots it is NO bottleneck :)
    Tobias was right :)

    Here they assume all relevant variables influencing behaviour are being observed. Namely, the relative positions and orientations of all ducks in the swarm. So, they make movies of the swarm's movements, process them, and them fit the models to that data.

    In the roots, though we can observe the complete final structure, or even obtain time-lapse movies showing how that structure came out to be, getting the measurements of all relevant soil variables (nitrogen, phosphorus, ...) throughout the soil, and over time, would be extremely difficult. So I guess a replication of the kind of work they did, but for the roots, would be hard.
    Nice reference though.

    How much remained in your head? Don't tell Tobias, but I scored only 5/10 :-(

    There's one question missing: how many of these designs are claimed to be baised on biomimicry just because this sells?? Tobi, please!

Fruit Fly Aerial Maneuver Explained - 1 views

  • Insects can execute flying feats more impressive than fighter jets, and a team of researchers has now learned the trick behind one of them. They used high speed video cameras and a new 3D reconstruction technique to show how fruit flies execute their acrobatic turns. As they report in the 9 April Physical Review Letters, despite the complex wing motions, a fly can execute quick pirouettes by adjusting just a single parameter that controls the difference between the way its left and right wings oscillate. The results may be relevant for engineers designing flight control strategies for tiny robotic insects for search-and-rescue and surveillance.
