We report on the observation of noise-free stochastic resonance in an externally driven diode resonator close to an interior crisis. At sufficiently high excitation amplitudes the diode resonator shows a strange attractor which after the collision with an unstable period-three orbit exhibits crisis-induced intermittency. In the intermittency regime the system jumps between the previously stable...

The deviations Scm (“intermittency corrections”) from classical (“K41”) scaling c,==m/3 of the mth moments ( 1 u(p) I”) in high Reynolds number turbulence are calculated, extending a method to approximately solve the Navier-Stokes equation described earlier. It is suggested to introduce the notion of scale resolved intermittency corrections Sk,(p), because these &L&(p) are found to be large in ...

A new class of transient transport near the critical gradient (CG) referred to as GAM growing intermittency due to the collision-less GAM damping has been found based on Landau-fluid simulation[Miki, et al., Phys. Rev. Letts. 99, 145003 (2007)]. Here, we present a new predator-prey model to understand the essential features of the growing intermittency. We have also extended the simulation mode...

We study the intermittency of fluid velocities in porous media and its relation to anomalous dispersion. Lagrangian velocities measured at equidistant points along streamlines are shown to form a spatial Markov process. As a consequence of this remarkable property, the dispersion of fluid particles can be described by a continuous time random walk with correlated temporal increments. This new d...

We report progress towards developing methods to forecast solar-power intermittency due to clouds using analysis of digital images taken with a ground-based, suntracking camera. We show preliminary results of blockmotion estimation analysis applied to a sequence of sky images recorded in Tucson, Arizona. In addition, we discuss statistics of ramp rates and duration of cloudinduced intermittency...

We investigate the origin of intermittency for multiparticle distribution in momentum space, following the idea that there is a kind of power law distribution of the space-time region of hadron emission. Using the formalism of current ensamble model to describe boson sources we discuss intermittency exponents for the coherent and incoherent ( chaotic) particle production scheme. PACS numbers:13...

We briefly discuss the status of the intermittency hypothesis, according to which the grand minima type variability in solar-type stars may be understood in terms of dynamical intermittency. We review concrete examples which establish this hypothesis in the mean-field setting. We discuss some difficulties and open problems regarding the establishment of this hypothesis in more realistic setting...
