This paper is concerned by the modal identification of time-varying mechanical systems. Based on previous works about autoregressive moving average models in vector form (ARMAV) for the modal identification of linear time invariant systems, and time-varying autoregressive moving average models (TV-ARMA) for the identification of nonstationary systems, a time-varying ARMAV (TV-ARMAV) model is presented for the multivariate identification of time-varying systems. It results in the identification of not only the time-varying poles of the system but also of its respective time-varying mode shapes. The method is applied on a time-varying structure composed of a beam on which a mass is moving. [less ▲]

To alleviate the computational burden of the nite element method for thermal analyses involving conduction and radiation, this paper proposes an automatic conductive-radiative reduction process based on the clustering of a detailed mesh coming from a structural model for instance. The proposed method leads to a signi cant reduction of the number of radiative exchange factors (REFs) to compute and size of the corresponding matrix. It further keeps accurate conduction information by introducing the concept of physically meaningful super nodes. The REFs between the super nodes are computed through Monte Carlo ray-tracing on the partitioned mesh, preserving the versatility of the method. The resulting conductive-radiative reduced model is solved using standard iterative techniques and the detailed mesh temperatures can be recovered from the super nodes temperatures for further thermo-mechanical analysis. The proposed method is applied to a structural component of the Meteosat Third Generation mission and is benchmarked against ESATAN-TMS, the standard thermal analysis software used in the European aerospace industry.

Our experiment aimed at studying the impact of long term tillage treatments – reduced tillage (RT) and conventional tillage (CT), on CO2 and N2O emissions by soil and at describing the dynamics of N2O fluxes. Gas measurements were performed from June to October 2015 in a Belgian maize crop, with homemade automated closed chambers, allowing continuous measurement at a high temporal resolution. After 7 years of treatment, CO2 and N2O average emissions were significantly larger in the RT parcel than in the CT parcel. This observation was attributed to the effect of tillage on the distribution of crop residues within the soil profile, leading to higher soil organic C and total N contents and a greater microbial biomass in the upper layer in RT. A single N2O emission peak triggered by a sudden increase of water- filled pore space (WFPS) was observed in the beginning of the measuring campaign. The absence of large emission afterwards was most likely due to a decreasing availability of N as crop grew. N2O background fluxes showed to be significantly correlated to CO2 fluxes but not to WFPS, while the influence of soil temperature remained unclear. Our results question the suitability of reduced tillage as a “climate-smart” practice and suggest that more experiments be conducted on conservation practices and their potent negative effect on environment.

Les recherches archéologiques conduites au sud-est du forum de la ville romaine de Baelo claudia ont permis de mettre au jour au-dessus du secteur monumental, plusieurs phases de transformation, d’abandon et de réoccupation entre les IIIe et VIe s. Les structures découvertes ainsi que le nombreux mobilier qui leur était associé (monnaies, céramique, verre, métal, faune, etc.) fournissent un éclairage nouveau sur l’histoire et la nature de l’agglomération dans l’antiquité tardive, qui entre la fin du IVe s. et son abandon définitif au VIe s. ressemble moins à une ville qu’à un gros village.

The purpose of this paper is to discern in what ways the semiotic methods of the Post- Greimasian French structuralist and the American Peircian traditions can enrich the study of contemporary methods of computational analysis of culture, particularly in the field of Cultural Analytics as implemented by the Russian Art Historian and Computer Scientist Lev Manovich. These semiotic approaches will be helpful in understanding what kinds of visualizations are being generated for use in Cultural Analytics, and what kinds of operations the observer must perform in order to experiment with scientific visualizations of this information.

En 2006, l’écrivain et essayiste allemand Hans Magnus Enzensberger publie Le perdant radical, un « essai sur les hommes de la terreur », conformément au sous-titre de cet ouvrage d’une soixantaine de pages dans lequel l’auteur décrit les multiples facettes d’un ensemble de figures meurtrières. Du tireur fou dans un lycée américain au combattant islamiste ceinturé d’explosifs, isolé ou organisé en groupe, tout perdant radical répond au même mécanisme : c’est « lorsqu’il aura repris à son compte le jugement des autres, ceux qu’il tient pour les gagnants (…) qu’il pète les plombs. » L’indistinction est frappante : pour Enzensberger, le perdant radical peut sévir seul ou en groupe ; son moteur profond, irréductible à un engagement politique ou religieux, reste le même dans les deux cas. Car pour l’essayiste, rien, pas même une théorie critique de la société, ne permet de rendre compte de la nature du perdant radical, si ce n’est la suppression de l’instinct de conservation. Dans plusieurs textes littéraires – on songe notamment à son poème Zur Frage der Bedürfnisse (1991) et à son entretien autobiographique fictif avec lui-même Erinnerungen an einen Tumult (2014) –, Hans Magnus Enzensberger crée ou recrée des figures de terroristes qui réalisent parfaitement le profil type du perdant radical. Andreas Baader, les jeunes bourgeois d’une secte marxiste en Suède, un terroriste islamiste en fuite, un guérillero sud-américain qui a perdu tout sens de la réalité, autant de figures fictionnelles ou refictionnalisées qui, partant d’une même position d’échec apparemment imposée de l’extérieur et assumée en tant que telle, superposent destruction et autodestruction. L’hypothèse générale à laquelle nous voudrions soumettre ces personnages de terroristes est qu’ils sont les héritiers d’une figure essentielle pour la littérature allemande et anglo-saxonne : l’amok.
