Judging the Intersection of Convex Polygons by Bracket Method [PDF]
Proceedings of the 2nd International Conference on Computer Application and System Modeling, 2012 In this paper, we study a basic problem based on bracket manipulations in computational geometry: how to judge if two solid convex polygons intersect or not. A key idea in our criteria is that the signs of some brackets of the homogeneous coordinates of the vertices of the two convex bodies are all we need in carrying out the judgment. Experiments show

Compatible Lie brackets related to elliptic curve
, 2005 For the direct sum of several copies of sl_n, a family of Lie brackets compatible with the initial one is constructed. The structure constants of these brackets are expressed in terms of theta-functions associated with an elliptic curve. The structure of

A comparison of traditional and computer-aided bracket placement methods
The Angle Orthodontist, 2011 Abstract Objective: To test the hypothesis that there is no difference in the accuracy of bracket placement produced by OrthoCAD iQ indirect bonding (IDB) and that of an in-house fabricated IDB system by measuring the quality of intra-arch dental alignment at the end of simulated orthodontic treatment.
