Analytical index of dynamic isotropy and its application to hexapods
Precision Engineering, 2018 Dynamic isotropy is a condition where eigenfrequencies of a robot are equal, which could be equivalent to the maximization of the lowest eigenfrequency.

It is well known that it is possible to deduce the Lorentz transformations solely on the basis of the principles of relativity, space-time homogeneity, and isotropy of space, without making any use of the principles of reciprocity and of the invariance of the velocity of light.

Surface orientation from texture: Isotropy or homogeneity (or both)? [PDF]
Vision Research, 1997 We examine two models for human perception of shape from texture, based on two assumptions about the surface texture: isotropy and homogeneity. Observers made orientation judgments on planar textured surfaces.

Previous work on posture optimization for robots has examined the condition number as a measure of kinematic dexterity. When the condition number equals an optimal value of one, the robot is described as isotropic. Isotropic configurations have a number of advantages, including good servo accuracy, noise rejection, and singularity avoidance.

Abstract Isotropic materials occupy a prominent position in the classical theory of plasticity. This subject is reconsidered here from the vantage point of the modern theory. It is shown that the classical theory of rigid-perfectly plastic materials emerges naturally from the modern framework based on material symmetry considerations ...

The presence of isolated acoustic noise sources in the ocean produces an anisotropic noise field. Hence, a hypothesis test for detection of these sources can be formulated as a test of H0 (isotropic noise field) versus H1 (anisotropic noise field).

Isotropy and anisotropy of the arterial wall
Journal of Biomechanics, 1988The passive biomechanical response of intact cylindrical rat carotid arteries is studied in vitro and compared with the mechanical response of rubber tubes. Using true stress and natural strain in the definition of the incremental modulus of elasticity, the tissue wall properties are analyzed over wide ranges of simultaneous circumferential and ...
