Surface textures can be isotropic or anisotropic. Anisotropic alloys generally have greater magnetic capacity in a preferred orientation than isotropic types. There are two independent Friedmann equations for modeling a homogeneous, isotropic universe. The material is assumed to be an isotropic, homogeneous, and linear elastic. Experimental investigations show that the observable universe is very close to isotropic and homogeneous. This simplified definition holds for a homogeneous and isotropic system. P. A conformal map has an isotropic scale factor. Coupling is mediated by two processes, dipolar (through space) and isotropic (through bond). However, most isotropic yield criteria correspond to convex yield surfaces. The basic model considered the ball as being a spherical shell with isotropic material properties. The valleys collectively act together to give an isotropic conductivity. They assign constant spatial coordinate values to observers who perceive the universe as isotropic. Sometimes, the scattering is more or less isotropic, i. e. In either approach, the fundamental notion is that of an isotropic subspace . The low temperature slows down the chemical reaction that produces isotropic etching.
