Not So Black? The Statistics of Albedo and Energy Recirculation on Hot Exoplanets
data analysis — (stars:) planetary systems
2010/3/8
[Abridged] We use a simple analytic model to analyze all of the published photometric observations of exoplanets. Our model has two parameters: the planets' Bond albedo, A, and its heat recirculation ...
Soliton Propagation through a Disordered System: Statistics of the Transmission Delay
Soliton Propagation Transmission Delay Disordered System
2010/4/6
We have studied the soliton propagation through a segment containing random point-like scatterers. In the limit of small concentration of scatterers when the mean distance between the scatterers is la...
Time independent seismic hazard analysis of Greece deduced from Bayesian statistics
Time independent seismic hazard analysis Greece Bayesian statistics
2009/12/11
A Bayesian statistics approach is applied in the seismogenic sources of Greece and the surrounding area in order to assess seismic hazard, assuming that the earthquake occurrence follows the Poisson p...
Experimental study of the statistics of slipping events in solid friction
Experimental study statistics of slipping events solid friction
2009/11/16
The statistics of the stick-slip motion is studied in two experiments, where elasticity is distributed either on a surface or on a volume. The rough surface is realised by embedding steel spheres in a...
Non-Gaussian statistics in space plasma turbulence:fractal properties and pitfalls
Non-Gaussian statistics space plasma turbulence fractal properties pitfalls
2009/11/16
Statistical properties of collisionless plasmas in the vicinity of the Earth's bow shock are investigated with the aim to characterize the intermittent behaviour of non- magnetohydrodynamic turbulence...
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...
Fractal time statistics of AE-index burst waiting times:evidence of metastability
Fractal time statistics AE-index burst waiting times evidence of metastability
2009/11/12
Recent observations and analyses evidenced that the magnetotail, as well as the magnetospheric dynamics are characterised by a scale-free behaviour and intermittence. These results, along with numeric...
Extremum statistics:a framework for data analysis
Extremum statistics framework for data analysis
2009/11/12
Recent work has suggested that in highly correlated systems, such as sandpiles, turbulent fluids, ignited trees in forest fires and magnetization in a ferromagnet close to a critical point, the probab...
Scaling statistics in a critical,nonlinear physical model of tropical oceanic rainfall
Scaling statistics critical,nonlinear physical model tropical oceanic rainfall
2009/11/12
Over the last two decades, concepts of scale invariance have come to the fore in both modeling and data analysis in hydrological precipitation research. With the advent of the use of the multiplicativ...
Response of a global atmospheric circulation model to spatio-temporal stochastic forcing:ensemble statistics
global atmospheric circulation model spatio-temporal stochastic forcing ensemble statistics
2009/11/12
The response of a simplified global atmospheric circulation model (PUMA) to spatiotemporal stochastic forcing is analyzed using the statistical measures originally developed for ensemble forecast eval...
Statistics of locally coupled ocean and atmosphere intraseasonal anomalies in Reanalysis and AMIP data
locally coupled ocean atmosphere intraseasonal anomalies Reanalysis AMIP data
2009/11/12
We apply a simple dynamical rule to determine the dominant forcing direction in locally coupled ocean-atmosphere anomalies in the National Centers for Environmental Prediction/National Center for Atmo...
Earthquake statistics in a Block Slider Model and a fully dynamic Fault Model
Earthquake statistics Block Slider Model fully dynamic Fault Model
2009/11/11
We examine the event statistics obtained from two differing simplified models for earthquake faults. The first model is a reproduction of the Block-Slider model of Carlson et al. (1991), a model often...
Lagrangian velocity statistics of directed launch strategies in a Gulf of Mexico model
Lagrangian velocity statistics directed launch strategies Gulf of Mexico model
2009/11/11
The spatial dependence of Lagrangian displacement and velocity statistics is studied in the context of a data assimilating numerical model of the Gulf Mexico. In the active eddy region of the Western ...
A nonextensive statistics approach for Langmuir waves in relativistic plasmas
nonextensive statistics approach Langmuir waves relativistic plasmas
2009/11/9
The nonextensive statistics formalism proposed by Tsallis has found many applications in systems with memory effects, long range spatial correlations, and in general whenever the phase space has fract...
It is shown that the BBGKY equations for a particle interacting with ideal gas imply exact relations between probability distribution of path of the particle, its derivatives in respect to the gas den...
