Self-organization in two-dimensional swarms.
We undertake a systematic numerical exploration of self-organized states in a deterministic model of interacting self-propelled particles in two dimensions. In the process, we identify various types of collective motion, namely, disordered swarms, rings, and droplets. We construct a "phase diagram," which summarizes our results as it delineates phase transitions (all discontinuous) between diso...
متن کاملSelf-organization of earthquake swarms
The temporal clustering of swarm activity di ers signi cantly from characteristics of aftershock sequences accompanying mainshocks. This is often assumed to be caused by crustal structure complexities and uid migration. However, the underlying mechanism is not yet fully understood, especially, the processes and conditions which lead to the apparent di erences between the swarm patterns and typi...
متن کاملSelf-Organization in the Two-Dimensional Kelvin-Helmholtz Instability
The evolution and relaxation of an initial shear flow subject to the Kelvin-Helmholtz instability are investigated via two-dimensional compressible hydrodynamic simulations and the calculus of variations. During the instability evolution the total kinetic energy remains almost constant, but the enstrophy decays rapidly by the selective dissipation with the artificial viscosity. The successive v...
متن کاملSelf-organization and symmetry-breaking in two-dimensional plasma turbulence
The spontaneous self-organization of two-dimensional magnetized plasma is investigated within the framework of magnetohydrodynamics with a particular emphasis on the symmetry-breaking induced by the shape of the confining boundaries. This symmetry-breaking is quantified by the angular momentum, which is shown to be generated rapidly and spontaneously from initial conditions free from angular mo...
متن کاملHormone-Inspired Self-Organization and Distributed Control of Robotic Swarms
The control of robot swarming in a distributed manner is a difficult problem because global behaviors must emerge as a result of many local actions. This paper uses a bio-inspired control method called the Digital Hormone Model (DHM) to control the tasking and executing of robot swarms based on local communication, signal propagation, and stochastic reactions. The DHM model is probabilistic, dy...
