Generation of equations for shell models of turbulence in the Maple system [PDF]
The paper describes a technology for the automated compilation of equations for shell models of turbulence in the computer algebra system Maple. A general form of equations for the coefficients of nonlinear interactions is given, which will ensure that ...

A renormalisation approach to excitable reaction-diffusion waves in fractal media [PDF]
Of fundamental importance to wave propagation in a wide range of physical phenomena is the structural geometry of the supporting medium. Recently, there have been several investigations on wave propagation in fractal media.

Deciphering acoustic emission signals in drought stressed branches: the missing link between source and sensor [PDF]
When drought occurs in plants, acoustic emission (AE) signals can be detected, but the actual causes of these signals are still unknown. By analyzing the waveforms of the measured signals, it should, however, be possible to trace the characteristics of ...

Wave speeds and Green’s tensors for shear wave propagation in incompressible, hyperelastic materials with uniaxial stretch [PDF]
Assessing elastic material properties from shear wave propagation following an acoustic radiation force impulse (ARFI) excitation is difficult in anisotropic materials because of the complex relations among the propagation direction, shear wave ...

Operative center of the geophysical prognosis in Izmiran [PDF]
IZMIRAN was founded about 65 years ago with one of the goals of carrying out geomagnetic prognoses. More or less, this activity has been developed during its entire history, but about 6 years ago this aim became sufficiently feasible due to the ...
