A new reduction on the size of the search space for cocyclic Hadamard matrices over dihedral groups D4t is described, in terms of the so called central distribution. This new searc...
We propose a matching algorithm secure against the wolf attack in one-to-one biometric authentications. Our proposal algorithm first executes a one-to-all comparison using a conve...
Abstract. In this paper, we present a more effective approach to clustering with eXtended Classifier System (XCS) which is divided into two phases. The first phase is the XCS le...
Graphical languages provide a powerful tool for describing the behaviour of quantum systems. While the use of graphs vastly reduces the complexity of many calculations [4,10], manu...
In many libre (free, open source) software projects, most of the development is performed by a relatively small number of persons, the “core team”. The stability and permanenc...
