We propose a dual-arm cyclic-motion-generation (DACMG) scheme by a neural-dynamic method, which can remedy the joint-angle-drift phenomenon of a humanoid robot. In particular, according to a neural-dynamic design method, first, a cyclic-motion performance index is exploited and applied. This cyclic-motion performance index is then integrated into a(More)
The analytical far-field expressions for the TE and TM terms and energy flux distributions in two off-axis superimposed nonparaxial Laguerre-Gaussian beams with azimuthal and radial indices l(1) = -l(2) = +1, p(1) = p(2) = 0 are derived and used to study the far-field properties including phase singularities and energy flux distributions of the resulting(More)
OBJECTIVE To validate the discharge, inflammation, polyps/edema (DIP) scoring system for the assessment of endoscopic sinus surgery (ESS) outcomes in patients with chronic rhinosinusitis (CRS). METHODS Thirty patients with CRS were included in this prospective study. All patients were evaluated before and 2 months after surgery. Baseline measures and(More)
Based on the vector Fresnel diffraction integrals, analytical expressions for the electric and magnetic components of first-order Laguerre-Gaussian beams diffracted at a half-plane screen are derived and used to study the electric and magnetic polarization singularities in the diffraction field for both two- and three-dimensional (2D and 3D) cases. It is(More)
The closed-form expression for the free-space propagation of superimposed Laguerre-Gaussian beams beyond the paraxial approximation is derived, and the composite polarization singularities formed by the transverse and longitudinal electric-field components are studied in detail. It is shown that there exist composite C-points and L-lines in vector(More)
On the basis of the vector Rayleigh-Sommerfeld diffraction integrals, the analytical expression for Gaussian vortex beams diffracted at a half-plane screen beyond the paraxial approximation is derived and used to study the polarization singularities formed by the transverse and longitudinal electric field components in the diffracted field. It is shown that(More)
