Singularity-free computation of quaternions from rotation matrices in E4 and E3
(2018)
Conference report
Open AccessA real orthogonal matrix representing a rotation in E4 can be decomposed into the commutative product of a left-isoclinic and a right-isoclinic rotation matrix. The double quaternion representation of rotations in E4 follows ... -
A fast branch-and-prune algorithm for the position analysis of spherical mechanisms
(Springer, 2019)
Conference report
Open AccessDifferent branch-and-prune schemes can be found in the literature for numerically solving the position analysis of spherical mechanisms. For the prune operation, they all rely on the propagation of motion intervals. They ... -
Fractal evaluation aspects in characterizing the roughness of a driving wheel from a locomotive
Conference report
Open AccessFor comprehending tribological phenomena such as wear, friction, contact deformation and tightness of contact joints is the essential characterisation of the multiple scale topography of roughness surfaces. Wheel roughness ...
