In the framework of linear transformations between inertial systems, there are no physical reasons for assuming any anisotropy in the one-way velocity of light. Pacs 03.30 Special relativity
We discuss, within a continuum Landau theory, the possibility of an anisotropy-reIated wetting transition in a semi-infinite cubic ferromagnet. This is then investigated for a specific value of anisotropy parameter, where it is shown to divide into two Ising model problems.
General criteria to check the positivity of the distribution function (phase–space consistency) of stellar systems of assigned density and anisotropy profile are useful starting points in Jeans– based modeling. Here we substantially extend previous results, and we present the inversion formula and the analytical necessary and sufficient conditions for phase–space consistency of the family of mu...
Large strains, anisotropy of mechanical properties of materials and Coulomb friction in contact regions are some properties in the analysis of deep drawing process. In this research, the effects of different parameters such as anisotropy coefficient, work hardening exponent and friction coefficient on deep drawing process of drawing quality steel are studied. For this purpose, the finite elemen...
In this work we investigated the critical properties of the anti-ferromagnetic XY model on a two dimensional Kagome lattice under single-ion easy-axes anisotropy. Employing the mean field theory, we found that this model shows a second order phase transition from disordered to all-in all-out state for any value of anisotropy.
Cohesive-frictional soils are widely used in the construction of embankment structures and due to the method of construction, i.e. applying compactive efforts in the vertical direction in these cases, the occurrence of anisotropy in the soil strength and permeability seems to be inevitable. In this study, attempts have been made to evaluate the shear strength of c-f soils through modifying a l...

تأثیر ناهمسانی مکانیکی و ناهمگونی پارامترهای مقاومت برشی خاک‌ها بر ظرفیت باربری دراز مدت پی‌های سطحی
Natural formation of soil deposits causes heterogeneity and anisotropy in their strength and stiffness properties. However, most soils in their natural states exhibit some anisotropy with respect to shear strength and heterogeneity with respect to the depth. In this paper, the standard Mohr- Coulomb constitutive law is generalized to anisotropic version in order to consider the effect of cohesi...
S U M M A R Y We developed an integrated technique for estimating crustal anisotropy with a horizontal axis using radial (R) and transverse (T) receiver functions. The technique includes computing three individual and one joint objective function (JOF) and a reliability analysis of the estimated anisotropy. The individual objective functions (IOFs) are designed to: (1) maximize the peak energy ...
