The device includes a body and an array of fibers attached thereto, with at least some of the fibers maintaining contact with the juxtaposed surface and having anisotropic surface friction therewith, such that mutual vibratory motion between the device and the juxtaposed surface causes the device to move along the surface.
Additionally, it was shown by researchers that although anisotropic diffusion filter was successful for additive noise, it was not good enough for image degraded speckle noise [8].
Participant T1-weighted structural data was segmented and combined with coregistered white matter diffusion tensors to define anisotropic conductivity finite element models.
[8] generalize the versatile model to the case of anisotropic shales by introducing tensorial versions of formation factor and tortuosity with the intention of quantifying the role played by kerogen on surface conductivity and quadrature conductivity.
It can be noted that dominance of an anisotropic stress gives rise to an anisotropic expansion.
With the increasing number of projects with composite materials came the need to calculate stresses and strains in material structures anisotropic. This task is more complicated than in isotropic materials, since the anisotropy increases the number of variables of the problem.
A phenomenon of plane electromagnetic wave propagation in vacuum parallel to an interface between vacuum and an anisotropic medium has been considered in [1].
The anisotropic permeability and drainage conditions influence the consolidation characteristics of these in situ soils.
In order to analytically investigate the propagation of wave in anisotropic inhomogeneous medium a novel matriciant method has been developed.
Theoretically, metamaterial can be considered biaxial anisotropic medium; that is, its permittivity and permeability are both diagonal tensors:
