Rectangular Corner Cutting Sylvester
This paper presents a way to construct the Sylvester A-resultant matrix for three bi-degree (m; n) polynomials whose exponent set is cut oo by rectangles at the corners. The paper also shows that the determinant of this matrix does give the resultant of the three polynomials.
متن کاملCorner cutting systems
If we can evaluate a curve by means of a corner cutting algorithm, we call the corresponding system of functions a corner cutting system. We prove that corner cutting systems are always monotonicity preserving. We obtain weak sufficient conditions for corner cutting systems. Optimal stability properties and properties concerning the supports of the basis functions of corner cutting systems are ...
متن کاملDescartes Systems from Corner Cutting
Here cI . . . . . c~ are vectors (control points) in some s-dimensional linear space, say W. The control polygon is then determined by the composite vector c r R "~ and we can think of c geometrically as a polygonal line. Various algorithms for the manipulation and computation of such curves take the form of successive geometric alterations of the control polygon. In particular, in the case of ...

Hence for each contact point...
متن کاملCutting-Tool Materials and Cutting Fluids
The reasons for the availability of a large variety of cutting-tool materials is best appreciated by reviewing the top eight parameters in the first column in Table 22.2 on p. 638. Among various factors, the type of workpiece material machined, the type of operation, and the surface finish and dimensional accuracy required all affect the choice of a cutting-tool material. For example, for inter...
