Quantifying scaling in the velocity field of the anisotropic turbulent solar wind [PDF]

open access: yes, 2007
Solar wind turbulence is dominated by Alfvénic fluctuations with power spectral exponents that somewhat surprisingly evolve toward the Kolmogorov value of −5/3, that of hydrodynamic turbulence.

Scaling Functions In Conical Indentation Of Elastic-Plastic Solids

open access: yes, 2008
The finite element method was used to simulate the conical indentation of elastic-plastic solids with work hardening. The ratio of the initial yield strength to the Young's modulus Y/E ranged from 0 to 0.02.

Scaling of solar wind e and the AU, AL and AE indices as seen by WIND [PDF]

open access: yes, 2002
We apply the finite size scaling technique to quantify the statistical properties of fluctuations in AU, AL and AE indices and in the parameter that represents energy input from the solar wind into the magnetosphere. We find that the exponents needed to

Ising model with varying spin strength on a scale-free network: scaling functions and critical amplitude ratios

open access: yesCondensed Matter Physics
Recently, a novel model to describe ordering in systems comprising agents which, although matching in their binarity (i.e., maintaining the iconic Ising features of “+” or “–”, “up” or “down”, “yes” or “no”), still differing in their strength was ...

Scaling Laws for Partially Developed Turbulence

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
We formulate multifractal models for velocity differences and gradients which describe the full range of length scales in turbulent flow, namely: laminar, dissipation, inertial, and stirring ranges.

The generalised scaling function: A note [PDF]

open access: yesNuclear Physics B, 2010
A method for determining the generalised scaling function(s) arising in the high spin behaviour of long operator anomalous dimensions in the planar $sl(2)$ sector of ${\cal N}=4$ SYM is proposed. The all-order perturbative expansion around the strong coupling is detailed for the prototypical third and fourth scaling functions, showing the emergence of ...

Anomalous scaling for Lagrangian velocity structure functions in fully developed turbulence

open access: yes, 2011
A hierarchical structure model is developed for anomalous scaling of the Lagrangian velocity structure functions in fully developed turbulence. This model is an extension of the Eulerian hierarchical structure model of She and Leveque [Phys. Rev.

Optimal scaling of the random walk Metropolis on unimodal elliptically symmetric targets. [PDF]

open access: yes, 2009
Scaling of proposals for Metropolis algorithms is an important practical problem in MCMC implementation. Criteria for scaling based on empirical acceptance rates of algorithms have been found to work consistently well across a broad range of problems ...

On the Approximate Solution of Partial Integro-Differential Equations Using the Pseudospectral Method Based on Chebyshev Cardinal Functions

open access: yesMathematics, 2021
In this paper, we apply the pseudospectral method based on the Chebyshev cardinal function to solve the parabolic partial integro-differential equations (PIDEs).

Scaling functions robust to translations [PDF]

open access: yesIEEE Transactions on Signal Processing, 1998
Summary: The discrete wavelet transform (DWT) is popular in a wide variety of applications. Its sparse sampling eliminates redundancy in the representation of signals and leads to efficient processing. However, the DWT lacks translation invariance. This makes it ill suited for many problems where the received signal is the superposition of arbitrarily ...
