Caligula, tyran dérisoire dans le Caligula d’Alexandre Dumas

This paper studies the character of Caligula in Alexandre Dumas’ Caligula (1837) in comparison with the image left by the Roman emperor in ancient literarysources. Dumas highlights a tyrannical regime based on denial and flattery, shows the emperor as a tyrannical lover and mocks aspirations to the divinityof the one who takes himself for Jupiter, but is afraid of thunder, who wants to be the master of the destiny of all, but doesn’t master his own, falling underMessalina’s machinations.This paper studies the character of Caligula in Alexandre Dumas’ Caligula (1837) in comparison with the image left by the Roman emperor in ancient literarysources.

Dumas en caricatures, dir. J. Anselmini et I. Safa

Julie Anselmini et Isabelle Safa introduisent (pp. 13-23) ce 45e numéro des “Cahiers Dumas” consacré à Dumas en caricatures. Outre leurs aspects techniques, leurs enjeux esthétiques et leur dimension politique, elles précisent combien le personnage de Dumas par sa truculence, ses amours à scandale, sa physionomie singulière, les caractères hauts en couleurs des personnages qu’il a inventés, a nourri cet art, éminemment populaire tout comme ses romans. Suivent donc cinquante-sept caricatures p..

An Improvement over the GVW Algorithm for Inhomogeneous Polynomial Systems

The GVW algorithm is a signature-based algorithm for computing Gr\"obner bases. If the input system is not homogeneous, some J-pairs with higher signatures but lower degrees are rejected by GVW's Syzygy Criterion, instead, GVW have to compute some J-pairs with lower signatures but higher degrees. Consequently, degrees of polynomials appearing during the computations may unnecessarily grow up higher and the computation become more expensive. In this paper, a variant of the GVW algorithm, called M-GVW, is proposed and mutant pairs are introduced to overcome inconveniences brought by inhomogeneous input polynomials. Some techniques from linear algebra are used to improve the efficiency. Both GVW and M-GVW have been implemented in C++ and tested by many examples from boolean polynomial rings. The timings show M-GVW usually performs much better than the original GVW algorithm when mutant pairs are found. Besides, M-GVW is also compared with intrinsic Gr\"obner bases functions on Maple, Singular and Magma. Due to the efficient routines from the M4RI library, the experimental results show that M-GVW is very efficient

Robust semantic analysis for adaptive speech interfaces

The DUMAS project develops speech-based applications that are adaptable to different users and domains. The paper describes the project's robust semantic analysis strategy, used both in the generic framework for the development of multilingual speech-based dialogue systems which is the main project goal, and in the initial test application, a mobile phone-based e-mail interface

Autographie von Alexandre Dumas entdeckt

Im Archivzentrum der UB Frankfurt wurde ein von Alexandre Dumas handgeschriebenes Gedicht gefunden. Dumas übersetzte die "Die nächtliche Heerschau" von Joseph Christian Freiherr von Zedlitz ins Französische und notierte sie auf eine Lithographie

Soliton Analysis of the Electro-Optical Response of Blue Bronze

In recent measurements on the charge-density-wave (CDW) conductor blue bronze (K0.3MoO3), the electro-transmittance and electro-reflectance spectra were searched for intragap states that could be associated with solitons created by injection of electrons into the CDW at the current contacts [Eur. Phys. J. B 16, 295 (2000); ibid 35, 233 (2003)]. In this work, we adapt the model of soliton absorption in dimerized polyacetylene to the blue bronze results, to obtain the (order of magnitude) estimate that current induced solitons occur on less than ~ 10% of the conducting chains. We discuss the implications of these results on models of soliton lifetimes and motion of CDW phase dislocations.Comment: 11 pages, including 1 figur

Tensile properties of palladium-silver alloys with absorbed hydrogen

The alloys 90Pd-10Ag, 80Pd-20Ag, 70Pd-30Ag, 60Pd-40Ag, and 50Pd-50Ag containing absorbed hydrogen were tested in tension. The results show the tensile properties to be independent of the phase transition. Also, hydrogen in the lattice does not necessarily cause embrittlement or poor elongation. The changes in the tensile properties appear dependent on the electron to atom site ratio
