nonlinear processes in geophysics geomagneticfield Earth's core fluid dynamics turbulence
2015/9/11
In the field of geomagnetism a number of studies have been devoted to the investigation of turbulence and intermittency in the outer core fluid motions. Here, in order to obtain information on such ph...
Ridgelets: a key to higher-dimensional intermittency?
higher-dimensional intermittency wavelets
2015/8/21
We discuss in this paper a new subject, ridgelet analysis, which can e®ectively
deal with linelike phenomena in dimension 2, planelike phenomena in dimension
3 and so on. It encompasses a colle...
Scaling and intermittency in incoherent α-shear dynamo
Dynamo – magnetic fi elds – MHD – turbulence
2011/10/8
We consider mean-field dynamo models with fluctuating \alpha effect, both with and without shear. The \alpha effect is chosen to be Gaussian white noise with zero mean and given covariance. We show an...

Abstract: We consider mean-field dynamo models with fluctuating \alpha effect, both with and without shear. The \alpha effect is chosen to be Gaussian white noise with zero mean and given covariance. ...
Noise induced state transitions, intermittency and universality in the noisy Kuramoto-Sivashinksy equation
Noise induced state transitions intermittency universality noisy Kuramoto-Sivashinksy equation
2010/11/18
We analyze the effect of pure additive noise on the long-time dynamics of the noisy Kuramoto-
Sivashinsky (KS) equation in a regime close to the instability onset. We show that when the noise is high...
Hysteresis and intermittency in a nano-bridge based suspended DC-SQUID
Hysteresis intermittency nano-bridge based suspended DC-SQUID
2010/11/11
We study voltage response of nano-bridge based DC-SQUID fabricated on a Si\_{3}N\_{4} membrane. Such a configuration may help in reducing 1/f noise, which originates from substrate fluctuating defects...
Intermittency route to chaos for the nuclear billiard - a quantitative study
Intermittency route chaos nuclear billiard
2010/4/7
We extended a previous qualitative study of the intermittent behaviour of a chaotical nucleonic system, by adding a few quantitative analyses: of the configuration and kinetic energy spaces, power spe...
Google matrix and Ulam networks of intermittency maps
Google matrix Ulam networks intermittency maps
2010/4/8
We study the properties of the Google matrix of an Ulam network generated by intermittency maps. This network is created by the Ulam method which gives a matrix approximant for the Perron-Frobenius op...
Multifractal intermittency of Eulerian and Lagrangian turbulence of ocean temperature and plankton fields
Multifractal intermittency Eulerian and Lagrangian turbulence ocean temperature plankton fields
2009/11/16
In this paper, we present evidence that intermittency of Eulerian and Lagrangian turbulence of ocean temperature and plankton fields is multifractal and furthermore can be analysed with the help of un...
Intermittency,non-Gaussian statistics and fractal scaling of MHD fluctuations in the solar wind
Intermittency,non-Gaussian statistics fractal scaling MHD fluctuations solar wind
2009/11/13
This paper gives a review of some recent work on intermittency, non-Gaussian statistics, and fractal scaling of solar wind magnetohydrodynamic turbulence. Model calculations and theories are discussed...

Intermittency MHD turbulence coronal nanoflares modelling
2009/11/9
High resolution numerical simulations, solar wind data analysis, and measurements at the edges of laboratory plasma devices have allowed for a huge progress in our understanding of MHD turbulence. The...
Multifractality and intermittency in the solar wind
Multifractality intermittency solar wind
2009/11/3
Within the complex dynamics of the solar wind's fluctuating plasma parameters, there is a detectable, hidden order described by a chaotic strange attractor which has a multifractal structure. The mult...

Multi-point observations intermittency cusp regions
2009/11/3
In this paper we investigate the statistical properties of magnetic field fluctuations measured by the four Cluster spacecraft in the cusp and close to the interface with the magnetospheric lobes, mag...

Structure function analysis intermittency atmospheric boundary layer
2009/11/2
Data from the SABLES98 experimental campaign (Cuxart et al., 2000) have been used in order to study the relationship of the probability distribution of velocity increments (PDFs) to the scale and the ...

2009/11/2
Low frequency electrostatic turbulence in the ionospheric E-region is studied by means of numerical and experimental methods. We use the structure functions of the electrostatic potential as a diagnos...
