We introduce an extension of the derivatives of rational expressions to expressions denoting formal power series over partially commuting variables. The expressions are purely non...
Abstract. Several existing procedural modeling systems are able to generate large 3D models of cities. However, none of these systems can automatically create 3D models of freeways...
With every σ-ideal I on a Polish space we associate the σ-ideal I∗ generated by the closed sets in I. We study the forcing notions of Borel sets modulo the respective σ-ideals...
Free tree, as a special graph which is connected, undirected and acyclic, is extensively used in domains such as computational biology, pattern recognition, computer networks, XML...
In this paper, we propose a generative model for representing complex motion, such as wavy river, dancing fire and dangling cloth. Our generative method consists of four component...
