Should we abandon cascade models to describe the spatial complexity of fully developed turbulence velocity profiles ?
J. Delour, J. F. Muzy, A. Arneodo
We perform one- and two-points magnitude cumulant analysis of one-dimensional longitudinal velocity profiles stemming from three different experimental set-ups and covering a broad…
Multifractal returns and Hierarchical Portfolio Theory
J. -F. Muzy, D. Sornette, J. Delour +1
We extend and test empirically the multifractal model of asset returns based on a multiplicative cascade of volatilities from large to small time scales. The multifractal descripti…
Velocity statistics in excited granular media
W. Losert, D. G. W. Cooper, J. Delour +2
We present an experimental study of velocity statistics for a partial layer of inelastic colliding beads driven by a vertically oscillating boundary. Over a wide range of parameter…
Velocity distributions in vertically vibrated granular media
J. Delour, A. Kudrolli, J. P. Gollub
This paper has been withdrawn by the authors. It has been superceded by an improved investigation: "Velocity statistics in vibrated granular media" W. Losert, D.G.W. Cooper, J. Del…
