COBBS – Computer Vision and Tracking

The raw data gathered from the experimental work consists of three sequences of images, one from each camera, for each flocking/swarming event. Each sequence may consist of up to 2700 images, meaning a single event could have a total of … Read the rest

COBBS – Non-biting Midge Experiment

Our search for midge swarms has taken us to many of the public parks within Rome including Riserva Naturale Valle dell’Aniene, Villa Paganini, Villa Torlonia, Parco dell’Acquedotto, Villa Ada, Laghetto dell’EUR and Ponte Tazio. Basically any place with an aquatic … Read the rest

COBBS – Collective Behaviour in Biological Systems

From bird flocks to fish schools, from insect swarms to cell colonies, collective behaviour is a very widespread phenomenon in many biological systems. It is hard to define, but easy to recognize. What are the mechanisms regulating collective behaviour in Read the rest

COBBS – Laboratory

The COBBS Laboratory is housed on the 4th floor of the Fermi Building, Sapienza University. This is our main lab space and houses the experimental team. The numerical analysis and computer vision teams are located two doors down the hallway … Read the rest

The growth of amorphous order in supercooled liquids

Close to the glass transition supercooled liquids display an impressive increase of the relaxation time, without any clear sign of growing thermodynamic order, nor correlation length. This is at variance with physical intuition, which suggests that a large relaxation time … Read the rest

The INFM-CNR/STARFLAG team

Here follows a very synthetic description of the role each one of the people in the INFM-CNR/STARFLAG team had:

  • Michele Ballerini (CNR-INFM)
    electronics, data taking
  • Nicola Cabibbo (La Sapienza)
    electronics design, experimental setup design
  • Raphael Candelier (La Sapienza and CEA)

Topological vs. Metric distance

Basically all existing models of collective animal behaviour (bird flocks, fish schools, etc) assume that the interaction between different individuals depends on the metric distance, just as in physics. This implies, for example, that two birds 5 meters apart … Read the rest

STARFLAG: a project on collective animal behaviour

Collective animal behaviour is a fascinating phenomenon. How does global co-ordination emerge in a flock of thousands starlings swirling at dusk? How does a school of sardines organize in a circular pattern? What is the evolutionary function of collective behaviour? Read the rest
