Time intermittency and spectral features of the geomagnetic field
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...

Ridgelets higher-dimensional intermittency
2015/6/17
In dimensions two and higher, wavelets can efficiently represent only a small range of the full diversity of interesting behavior. In effect, wavelets are welladapted for pointlike phenomena, whereas ...
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...
Risk Quantification Associated with Wind Energy Intermittency in California
California renewable energy risk analysis systems engineering wind power generation
2010/3/10
As compared to load demand, frequent wind energy
intermittencies produce large short-term (sub 1-hr to 3-hr)
deficits (and surpluses) in the energy supply. These intermittent
deficits pose systemic...
Effect of Wind Intermittency on the Electric Grid：Mitigating the Risk of Energy Deficits
California renewable energy risk analysis systems engineering wind power generation
2010/3/10
Successful implementation of California’s
Renewable Portfolio Standard (RPS) mandating 33 percent
renewable energy generation by 2020 requires inclusion of a
robust strategy to mitigate increased r...
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 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...
