The article focuses on studying the crankshaft as an essential part of marine internal combustion engine. Typical defects crankshafts diesel engines are considered. loads causing curvature a axis under operating conditions indicated. causes and nature violation shaft geometry determined. statistical assessment in cases axle warping during operation is found necessary. recommendations Russian Ma...

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...

In this paper, the classic straightening out theorem from di erential geometry is used to derive necessary and su cient conditions for locally converting rectangular di erential inclusions to constant rectangular di erential inclusions. Both scalar and coupled di erential inclusions are considered. The results presented in this paper have use in the area of computer aided veri cation of hybrid ...
