Ideal power converters are governed by differential equations with discontinuous right-hand sides. General-purpose algorithms to compute their Lyapunov exponents assume smooth equ...
E-learning by doing is an important e-learning process, that provides several advantages but that requires a high interactivity degree, not always supported in e-learning contexts...
Transitive roles are important for adequate representation of knowledge in a range of applications. In this paper we present a first algorithm to compute least common subsumers i...
In this paper, we document the evolution of a banner ad delivery system from a simple CGI script written in Perl running on a single host into a distributed computing application ...
Based on a result of Nies on definability the upper semilattice of computably enumerable degrees (denoted by R), we find that in R filters generated by definable subsets are al...
