We introduce the weak gap property for directed graphs whose vertex set S is a metric space of size n. We prove that, if the doubling dimension of S is a constant, any directed gra...
In 2002, Micali and Rivest raised an open problem as to whether directed transitive signatures exist or not. In 2003, Hohenberger formalized the necessary mathematical criteria for...
Executable UML models are nowadays gaining interest in embedded systems design. This domain is strongly devoted to the modeling of reactive behavior using StateChart variants. In ...
Although undirected cycles in directed graphs of Bayesian belief networks have been thoroughly studied, little attention has so far been given to a systematic analysis of directed ...
The effectiveness of direct volume rendering is difficult to validate and users may not know whether they have successfully explored the data or not. This limits its applications....
