Isotropic and anisotropic electroconvection

Physics Reports, 2007
A systematic overview of various electric-field induced pattern forming instabilities in nematic liquid crystals is given. The standard hydrodynamic description of nematics predicts the occurrence of striped patterns (rolls) in various wavenumber ranges, which depend on the anisotropy of the dielectric permittivity and that of the electrical ...

DTI MEASUREMENTS OF ISOTROPIC AND ANISOTROPIC MEDIA

Biomedizinische Technik/Biomedical Engineering, 2002
The ability to measure different rates of diffusion along different directions is one of the features that distinguish DTI from other imaging methods. It allows to extract and visualize information on tissue microstructure and microdynamics. However, to correctly determine the full diffusion tensor, the so-called b-matrix has to be calculated by taking

Isotropic and anisotropic interphases in polymer systems

Composite Interfaces, 2000
A polyisoprene-poly 4-vinyl pyridine (PIP/P4VP) diblock polymer has been used as adsorbate and adhesive on PVC and PMMA substrates. The diblock polymer is able to undergo surface restructuring, the rubber constituent being preferentially surface localized during contact with non-polar media, the P4VP moiety becoming dominant when in contact with polar ...

Isotropic and anisotropic spiraling photorefractive solitons

Conference Digest. 2000 Conference on Lasers and Electro-Optics Europe (Cat. No.00TH8505), 2002
Summary form only given. The interaction of photorefractive (PR) solitons has attracted considerable research interest in recent years. Screening solitons emerge when laser beams of appropriate wavelength, intensity, and shape are launched into a PR crystal and a dc electric field is applied across, to induce self-focusing of beams through PR screening.

ISOTROPIC AND ANISOTROPIC POLARIZATIONS OF MAGNETORHEOLOGICAL ELASTOMER

Journal of Defence Science, Engineering & Technology, 2023
The purpose of this research is to investigate the effect of varying currents injected into the coil during the curing process of magnetorheological elastomer (MRE) fabrication. In preparing MRE material, two types of MRE can be developed based on the curing process method fabrication which is isotropic and anisotropic.

Instability of rotating isotropic and anisotropic plasmas

Astrophysics and Space Science, 1985
The instability in a horizontal layer of stratified compressible isotropic and anisotropic plasmas has been studied to include simultaneously the effects of Coriolis forces and the finiteness of the ion Larmor radius. Using an integral approach, the dispersion relation has been derived in both cases for plasmas having density stratified exponentially ...

Isotropic and anisotropic turbulence in Clebsch variables

Chaos, Solitons & Fractals, 1995
Abstract Three-dimensional turbulence of incompressible fluid is described by using Clebsch canonical variables. This reveals the families of new local integrals of motion so that there are additional cascade spectra besides the energy cascade. A weakly anisotropic spectrum of developed turbulence is shown to be as universal as isotropic Kolmogorov ...
