The yield map is generated by fitting the yield surface shape of yield monitor data mainly using paraboloid cones on floating neighborhoods. Each yield map value is determined by the fit of such a cone on an elliptical neighborhood that is wider across the harvest tracks than it is along them. The coefficients of regression for modeling the paraboloid cones and the scale parameter are estimated...

This paper deals with yield mapping on the basis of monitor yield data. Every value of the yield map is determined by fitting paraboloid yield surface textures on floating neighbourhoods, but in a robust way so that the influence of outliers is bounded or completely annihilated. The neighbourhood used for fitting the paraboloid cone looks like a huge butterfly flying along the harvest track. In...

A two-dimensional (2D) shearography with source displacement is proposed to measure object contours. Using a dual-shear shearographic setup two movable laser sources, the full-field slopes along pair of orthogonal shear directions were obtained. The contour was then obtained by performing 2D integration surface slopes. Theoretical derivations and experimental results are presented demonstrate p...

In this numerical study, the effect of quartic autocatalysis type chemical reaction, buoyancy force and thermal radiation phenomenon magnetic on tangent hyperbolic nanofluid past an upper horizontal surface a paraboloid has been studied. By considering Buongiorno model approach, diffusion unequal coefficients in presence gyrotactic microorganism is discussed. Implementation microorganism's idea...

For a set S of distinct points in the x-y plane and a 3-dimensional surface with the general quadratic equation f ey dx cxy by ax z + + + + + = 2 2 we study the problem of finding a locally optimal triangulation of S for the linear approximation of the surface under the Lp norm. We show that the Lp norm error is independent of the translation and rotation by 180 degrees of a single triangle in ...

In this article, we study the intersection (or union) of the convex hull of N confocal paraboloids (or ellipsoids) of revolution. This study is motivated by a Minkowskitype problem arising in geometric optics. We show that in each of the four cases, the combinatorics is given by the intersection of a power diagram with the unit sphere. We prove the complexity is O(N) for the intersection of par...
