A software system for semi-automatic segmentation of the patellar cartilage is introduced. Providing tools for sub-pixel accurate edge tracing, automatic contour completion, and ad...
A Laman mechanism is a flexible planar bar-and-joint framework with m ≤ 2n−3 edges and exactly k = 2n− m degrees of freedom. The slider-pinning problem is to eliminate all ...
Let P be a set of n points in the plane. A connecting line of P is a line that passes through at least two of its points. A connecting line is called ordinary if it is incident on...
A thrackle is a drawing of a simple graph on the plane, where each edge is drawn as a smooth arc with distinct end-points, and every two arcs have exactly one common point, at whi...
