Multicollinearity Reconsidered

In this paper we intend to improve the explanatory power of regressions when the deletion method is used for the remedy of Multicolinearity. If one deletes the variable (s) that is (are) responsible for Multicolinearity, he loses some information that is not common between the deleted variable (s) and the other remaining variables in the regression. To improve this method, we run the deleted va...

Papyrus for Education (Invited Presentation)

The CEA List laboratory has recently launched an initiative to define a version of Papyrus dedicated to education and/or beginners that are interested in using a fully UML/SysML compatible open source tool, but without the complexity of a complete tool. This short article provides the latest improvements on this initiative and discuss the possible and expected contributions from the community.

Reportrapport Declarative Interpretations Reconsidered Declarative Interpretations Reconsidered

Three semantics have been proposed as the most promising candidates for a declarative interpretation for logic programs and pure Prolog programs: the least Herbrand model, the least term model, i.e. the C-semantics, and the S-semantics. Previous results show that a strictly increasing information ordering between these semantics exists for the class of all programs. In particular, the S-semanti...

Nemesis Reconsidered

The hypothesis of a companion object (Nemesis) orbiting the Sun was motivated by the claim of a terrestrial extinction periodicity, thought to be mediated by comet showers. The orbit of a distant companion to the Sun is expected to be perturbed by the Galactic tidal field and encounters with passing stars, which will induce variation in the period. We examine the evidence for the previously pro...
