Recognizing the limitations of existing distributions for 3-D rotations, Bingham et al. (2009a) developed the Uniform Axis-Random Spin (UARS) class of distributions.
Using the same values of κ and n, a second data set was simulated from the rotationally symmetric von Mises version of the Uniform Axis-Random Spin distributions, vM-UARS(I 3×3, κ) (Bingham et al. 2009).
Recognizing the limitations of existing distributions for 3-D rotations, Bingham et al. (2009) developed the Uniform Axis-Random Spin (UARS) class of distributions, Bingham et al. (2012) developed the Preferred Axis-Random Spin (PARS) class of distributions, and Oualkacha and Rivest (2009) developed a new model for symmetric axial directional data.
This analysis step is therefore best performed on data obtained from tissues with a uniform optic axis orientation.
In the image without correction there is however a false indication of a uniform optic axis orientation around the fovea, which was due to the data deviating from the SU 2) form in the analysis of section 4.3.
The method presented in this paper can therefore be applied with minimal modifications to other OCT applications (e.g. skin imaging) where also birefringent tissue with a locally uniform optic axis orientation is available.
The postbuckling behaviour of Pultruded Fibre-Reinforced Plastic (PFRP) beams in uniform major-axis bending is analysed through a nonlinear finite element (FE) analysis including initial out-of-straightness.
This work aims at presenting and discussing Generalised Beam Theory (GBT) numerical results concerning the elastic geometrically non-linear behaviour of simply supported lipped channel (LC) beams under uniform major-axis bending and experiencing distortional-global (D-G) interaction, making it possible to shed fresh light on the mechanics underlying this coupling phenomenon.
Both the thickness of the plate and stiffness of the elastic foundation are uniform along one axis and variable along the other axis.
It is noted that the diameters are not apparently uniform along the axis of the core samples.
This method can be seen as a correction or extension of Kaufman's theory to more complex scenarios, in which the casing is no longer assumed to be uniform along the axis of the borehole.
