The axisymmetric Navier-Stokes equations describe the motion of incompressible fluids under the assumption of rotational symmetry around a fixed axis. This reduction in dimensional complexity retains ...

Existing single point diamond turning machines are capable of fabricating complex aspheric optical surfaces; however, the machine tool limits these surfaces to ones of revolution. Introducing a high ...

The advent of four axis SPDT enables the generation of non-axisymmetric surfaces. This tool has two extra motions in addition to the orthogonal two axes of motion (x and z axes) featured in a SPDT ...

Small-angle neutron scattering (SANS) is the most significant neutron technique in terms of impact on science and engineering. However, the basic design of SANS facilities has not changed since the ...
