Natural Swarms in Dimensions
Andrea Cavagna, Luca Di Carlo, Irene Giardina +5
The dynamical critical exponent of natural swarms of insects is calculated using the renormalization group to order . A novel fixed point emerges, where both activity a…
CoMo: A novel co-moving 3D camera system
Andrea Cavagna, Xiao Feng, Stefania Melillo +3
Motivated by the theoretical interest in reconstructing long 3D trajectories of individual birds in large flocks, we developed CoMo, a co-moving camera system of two synchronized h…
Stereo camera system calibration: the need of two sets of parameters
Riccardo Beschi, Xiao Feng, Stefania Melillo +2
The reconstruction of a scene via a stereo-camera system is a two-steps process, where at first images from different cameras are matched to identify the set of point-to-point corr…
Marginal speed confinement resolves the conflict between correlation and control in natural flocks of birds
Andrea Cavagna, Antonio Culla, Xiao Feng +7
Speed fluctuations of individual birds in natural flocks are moderate, due to the aerodynamic and biomechanical constraints of flight. Yet the spatial correlations of such fluctuat…
