Phase synchronized states can emerge in the collective behavior of an ensemble of chaotic coupled map lattices, due to a mean field interaction. This type of interaction is responsible for synchronized chaotic global activity of the lattices, while the local activity of each map remains unsynchronized. The resulting collective dynamics is called " weak… (More)
This paper presents the design and simulation of an electromagnetic lens for a Half Impulse Radiating Antenna (HIRA). Simulation results showing the effectiveness of the lens in producing a spherical wave front and the behavior of the reflection coefficient and the transmission coefficient of the lens are presented and discussed.
The 58 Ni(n, γ) cross section has been measured at the neutron time of flight facility n TOF at CERN, in the energy range from 27 meV up to 400 keV. In total, 51 resonances have been analyzed up to 122 keV. Maxwellian averaged cross sections (MACS) have been calculated for stellar temperatures of kT = 5 − 100 keV with uncertainties of less than 6%, showing… (More)
A simplified model of leader development based on physical and engineering approximations for laboratory long gap discharges under switching impulses was proposed and tested. The model was derived from the physical analysis proposed by Bondiou-Gallimberti and the engineering approximation for the potential drop on the tip of the leader proposed by Rizk. The… (More)
