The phrase "a random orientation of" is correct and usable in written English.
It can be used when discussing the arrangement or positioning of objects or elements in a non-specific or arbitrary manner.
Example: "The experiment required a random orientation of the samples to ensure unbiased results."
Alternatives: "an arbitrary arrangement of" or "a haphazard positioning of".
A polymer with a random orientation of groups is said to be atactic.
In a second stage, we have estimated by homogenization methods the averaged stiffnesses , the Young modulus and Poisson ratio of polycrystalline TixTa1 − xN (0 ≤ x ≤ 1) alloys considering a random orientation of crystallites.
A simultaneously induced alignment of the crystallite c-axes with the draw direction, accompanied by a random orientation of the crystallite a-axes and b-axes, was also observed.
As a result of electronic microscopy observations the amorphous nature of the high conductivity AgIAg oxysalt electrolytes seems due to a random orientation of structurally ordered microdomains having less than 1 micron size.
We use Glen's law for secondary creep of ice as the material model and account for the anisotropic creep behaviour of single crystals by assigning individual network strands a random orientation of the c-axis.
A "mushroom-like" nanotube pillar is observed, where a random orientation of carbon nanotubes is located at the top of the pillars while the growth is more aligned near the base.
However, chitin microfibrils have a random orientation instead of being arranged in parallel.
Flanking bars were manipulated independently of the target, with each having a random orientation within 30° of vertical in intervals of 5°.
Regenerative (repair) tissue from microfracture treatment of an equine cartilage defect showed significant changes in collagen distribution and loss in proteoglycan content compared to the adjacent normal cartilage, with collagen fibrils demonstrating a random orientation in most of the repair tissue.
It was shown that both Schwann cells and axons of sympathetic neurons were parallel oriented onto the MCs of elliptical shape, while they exhibited a random orientation onto the MCs of arbitrary shape.
In the aberrated case the irregular irradiance distribution with hot spots would cause a more random orientation of the current with a more random distribution of gas bubbles which could explain the observed more isotropic distribution.
