A method for computing nonlinear soft–tissue deformation caused by simulated surgical procedures is presented. A mass–spring system is used to model patient individual soft–tissue. Instead of simulating dynamic behaviour, the introduced approach directly estimates the rest position of the system. Very fast and robust nonlinear soft–tissue deformation is computed using an optimization approach. ...

Abstract. This article establishes a system of anti-bud injury in sugarcane cutting based on computer vision using MATLAB software as a development platform. The seedcane cutter box cuts twice each turn. Match the accurate shutter trigger time interval according to the rotation speed of the cutter , the transportation speed of sugarcane, in order to make the position of collected image of the t...

In this work we are interested in perhaps nature’s most complex system, the mammalian cerebral cortex [1]. Recent advances in experimental neuroscience allow, for the first time, noninvasive studies of white matter tracts in the human nervous system, thus making available cutting-edge anatomical data describing these global connectivity patterns. Further, contemporary “proof of principle” work ...

Accuracy of machined component is one of the most critical considerations for any manufacturer. Many key factors like cutting tool and its setting angle, machining conditions, resolution of the machine tool and the type of work place etc., play an important role. However, once these are decided upon, the consistent performance of the machine tool depends upon its ability to accurately position ...

This paper presents a positioning strategy for flank milling ruled surfaces. It is a modification of a positioning method developed by Bedi et al. [1]. A cylindrical cutting tool is initially positioned tangential to the two boundary curves on a ruled surface. Optimization is used to move these tangential points to different curves on the ruled surface to reduce the error. A second optimization...

In this position paper, we present some problems we face in the development of an integrated software application for broadcast planning. Concretely, we’ll discuss customization and authorization. Our current implementation of both issues suffers from heavy cross-cutting and codetangling. Therefore we would like to present these problems at the ECOOP 2000 workshop on aspect-oriented programming...

We study the monotonicity properties of solutions in the classic problem of fair cake-cutting — dividing a heterogeneous resource among agents with different preferences. Resourceand population-monotonicity relate to scenarios where the cake, or the number of participants who divide the cake, changes. It is required that the utility of all participants change in the same direction: either all o...
