Approach is based on the considering of a small change of a cylindrical body volume with generatrix during the compression process.
However, the working surface of the input or output disc is the spherical surface, which induces the generatrix to be a circular arc.
In general, the rounded square shape has the axis of the handle vertical through the pot body, perpendicular and pointing to the horizontal plane; and a round shape has the axis of the handle perpendicular to the generatrix of the pot body, pointing to the barycentre on the body.
An efficient two-dimensional OSI formula, obtained by choosing the spiral step equal to the sample spacing needed to interpolate the data along a meridian curve (radial line, generatrix, and meridian), allows one to recover the NF data required to perform the NF-FF transformation using the corresponding classical scanning.
Considering of the variation of revolver radius with generatrix, an arbitrary revolver has to be described with cylindrical coordinate (r, [theta], z).
However, AuraPortal, thanks to its exclusive and innovative system known as Generatrix, offers a user-friendly system which uses checkboxes and drop-down menus to create any type of process, even the most complex, with no need whatsoever for any programming.
1(b), s is the local coordinate along a cone generatrix (in mathematics, the surface traced by a moving straight line (the generatrix) that always passes through a fixed point (the vertex).
When base and slant altitude of lateral surface for truncated pyramid and generatrix of lateral surface for truncated cone are expressed via % and a area of principle stress action in the compression zone may be determined using simple geometrical formulas:
As a way of example, two five-DOF trajectories of the centre of the mobile platform are analysed: a circular path with Euler angles equal to zero and a conical path in which the vector perpendicular to the mobile platform is taken as the generatrix of a cone.
Origin of the spatial coordinate is on external surface of the strip, axis y is directed to center of the drum, and axis x--along generatrix of the cylinder.
On the one hand, the Virgin embodies the archetype of the great mother, fertile generatrix of life and bearer of the Savior-Logos.
The simplest logic posits order: the basest survival instinct is insistent appeal for order, for primal form: the whole nervous system's constantly jostled continuities and particularities of thought prompt thought's ultimatum--ordered form (to degree of agnostic, atheistic negation/positivistic BELIEF) in "crystal clear", like we say--giving that "cluster" of, then, centered idea the word "God": gender, generatrix, generator, evermore.
