The weight-transfer effect, consisting of the change in dynamic load distribution between front and rear tractor axles, is one most impairing phenomena for performance, comfort, safety agricultural operations. Excessive weight transfer from to axle can occur during operation or manoeuvring implements connected through three-point hitch (TPH). In this respect, an optimal design TPH ensure better...

This paper presents a NC toolpath generation strategy with tool engagement control for arbitrarily complex discrete part geometry, which reduces machining time and tool wear and can be used in high speed machining. Simulations and comparison with existing methods are presented.

In this paper, a generic uniform scallop tool path generation method for five-axis machining is presented. Unlike the conventionalmethodswhich are based on the local surface geometry assumptions, thismethod is inspired by cutting simulation. Initially, the designed surface is planted with dense grasses. If a cutter is put onto the surface, the affected grasses will be cut short. All the affecte...

Thom polynomials measure how global topology forces singularities. The power of Thom polynomials predestine them to be a useful tool not only in differential topology, but also in algebraic geometry (enumerative geometry, moduli spaces) and algebraic combinatorics. The main obstacle of their widespread application is that only a few, sporadic Thom polynomials have been known explicitly. In this...

This chapter introduces some basic concepts and ideas of computer vision, such as imaging geometry of cameras, single view geometry, and two-view geometry. In particular, the chapter presents two practical examples. One is on single view metrology, calibration, and reconstruction; the other is a hybrid method for reconstruction of structured scenes from two uncalibrated images. Mathematics is t...

This paper describes an ongoing implementation of an open source library dealing with parametric representation of dynamic geometry constructions. We show how some current issues in standard dynamic geometry environments, such as computing envelopes of lines which are not primitive objects known by the geometric system, can be efficiently solved using the correspondence between geometry and alg...

We present an extension of the usual projective geometric framework for computer vision which can nicely take into account an information that was previously not used, i.e. the fact that the pixels in an image correspond to points which lie in front of the camera. This framework, called the oriented projective geometry, retains all the advantages of the unoriented projective geometry, namely it...
