Interface design normally follows the traditional approach of Art and Design, which requires reworking to refine an idea through visual playfulness until a solution has been achiev...
This paper presents algorithms for computing offsets of NURBS curves and surfaces. The basic approach consists of four steps: (1) recognition of special curves and surfaces; (2) s...
We compute the singular points of a plane rational curve, parametrically given, using the implicitization matrix derived from the -basis of the curve. It is shown that singularity...
We propose a new method to compute bid prices in network revenue management problems. The novel aspect of our method is that it naturally provides dynamic bid prices that depend o...
Abstract. The ability to move is an important characteristic of the human condition and an important aspect for interactive settings. The role of body movement however was not addr...
