At same time, on this line, all must be feed-through ones. dimensions and principles operation mechanism shown. main mechanisms conveyor string conveyors, cutting pressure roller...

This paper addresses the following question: Given a planar poly-line drawing of a graph, can we “straighten it out”, i.e., convert it to a planar straight-line drawing, while keeping some features unchanged? We show that any y-monotone poly-line drawing can be straightened out while maintaining y-coordinates and height. The width may increase much, but we also show that on some graphs exponent...

The study tests the validity of tensile hot ductility test for assessing cracking during straightening operation. Steels with a thin film deformation induced ferrite (DIF) or fully auste...

0. Introduction J.A. Green 6, x4] introduces codeterminants, which are products of pairs of natural basis elements of the Schur algebra S(n; r). These are shown to be parametrised by pairs of row-semistandard tableaux of shape , where 2 (n; r). If both the tableaux are standard, and the composition is dominant, then the codeterminant is said to be standard. The set of standard codeterminants fo...
