On the one hand, mashups are a new kind of web application built upon the composition of different resources in a user-friendly way. Tools based on such concepts focus on graphic ...
We analyze degeneracy of lower envelopes of algebraic surfaces. We focus on the cases omitted in the existing complexity analysis of lower envelopes [Halperin and Sharir 1993], an...
OWL ontologies are complex computational artifacts that are intimately connected with conceptual information and with application issues that are not easily explicable in the conte...
Abstract— We propose in this paper a generalization of percolation processes in Z2 using the pretopology theory. We formalize the notion of neighborhood by extending it to the co...
