A novel inverse kinematics method for 6-DOF robots with non-spherical wrist
, 2021A novel numerical method is proposed to solve the inverse kinematics for 6-DOF robots with non-spherical wrist in this paper, which firstly simplifies the non-spherical wrist structure to a spherical one.

Calibration of the discrete element method: Strategies for spherical and non-spherical particles
, 2020The discrete element method (DEM) is a numerical tool used for the modelling of granular materials. However, accurate predictions of material behaviour can only be made if the input parameter values are carefully selected.

PULL BACK RELATION FOR NON-SPHERICAL KNOTS
Journal of Knot Theory and Its Ramifications, 2004We introduce a new relation for high dimensional non-spherical knots, which is motivated by the codimension two surgery theory: a knot is a pull back of another knot if the former is obtained as the inverse image of the latter by a certain degree one map between the ambient spheres.

In laser-powder bed fusion (L-PBF) additive manufacturing, the powder particles commonly produced by gas atomization have some non-sphericities. It is known that non-spherical particles affect the particle packing process, however, there is a limited ...

MEASURING NON-SPHERICAL OPTICAL SURFACES
Contact Lens and Anterior Eye, 2001More lens designs for the presbyopic market are emerging and the use of novel constructions to generate varifocal optics in contact lenses is increasing. A number of designs incorporate aspheric shapes, of known p-values on the front and back surface of contact lenses.

AbstractSimple pseudo‐spherical harmonic expansions over non‐spherical surfaces are proposed for two body functions such as pair potentials and pair correlation functions of anisotropic fluids. It is shown that the thermodynamics of fluids with Gaussian overlap potential with constant well depth (GOCE fluids) can be calculated from only the leading ...
