3. Y coordinate of the surface normal vector. 4. Z coordinate of the surface normal vector. 5. The average Gaussian curvature of several sampling points on the surface. 6. The average mean curvature of several sampling points on the surface. 7. The surface type (e.g., plane, cylindri...
By contrast, polarization metasurface optics not only have the advantages of ultra-compactness, lightweight and relatively high efficiency, they also provide a powerful tool to simultaneously control both the polarization states and phase profiles, in line with the trend toward miniaturized optical ...
[13, 14] proposed a general on-line contour error estimation method, which searched for the point closest to the actual tool tip point on the command interpolation linear segment as the contour foot point to estimate the contour error. This algorithm has strong real-time performance. But due ...
Vision-based automatic welding guidance technology plays an essential role in robotic welding. A laser vision sensor (LVS) relies on manual intervention to guide the robot when near the workpiece, which reduces the autonomy of the welding robot and produ
inside (negative) or outside (positive). We use hardware gradients to approximate a screen-space signed distance to the curve boundary. This signed distance is used for antialiasing the curved boundaries. We can apply an arbitrary projective transform to view our plane curves in 3D. The res...
The problem of evaluating potential integrals on planar triangular elements has been addressed using a polar coordinate decomposition. The resulting formulae are general, exact, easily implemented, and have only one special case, that of a field point lying in the plane of the element. Results are...
1 consists of a double-symmetric twin-box cross-section bridge girder at roughly 15 m height, covering roughly 4360 m of roadline and has a curvature of 5000 m in the horizontal plane. The bridge girder is connected to 21 floating pontoons every 197 m with two circular columns....
How do you walk to create a straight line (on a Position-Time Graph )that slopes up? Position-Time Graph: A Position-Time graph represents the position of the object with respect to time. By using the Position-Time graph, we can calculate the velocity of the object ...
given by the advanced time coordinate \(v=t+r\) rather than u . radiative gauge fields: a linear, negative helicity spin-1 field is described by its linearised asd field strength \(\phi _{\alpha \beta }(x)\) , which obeys the zero-rest-mass equation \(\partial ^{\alpha \dot{\...
As a result of the Coanda effect, a symmetrical free jet will flow as an asymmetrical wall jet. At the same time, at the obstacle along which the flow is observed, the wall jet generates pressure distribution. In this study, the obstacle located at the d
