Many previous works involving physical models, excised and in vivo larynges have pointed out nonlinear vibration in vocal folds during voice production. Moreover, theoretical studies involving mechanical modeling of these folds have tried to gain a profound understanding of the observed nonlinear phenomena. In this context, the present work uses the nonlinear normal mode theory to investigate the nonlinear modal behavior of 16 subjects using a two-mass mechanical modeling of the vocal folds. The free response of the conservative system at different energy levels is considered to assess the impact of the structural nonlinearity of the vocal fold tissues. [less ▲]

This paper presents a centralized control scheme to regulate distribution network voltages in the presence of dispersed generation. The algorithm resorts to model predictive control to smoothly bring unsatisfactory voltages inside the desired range of values. Using a sensitivity model, the controller calculates optimal power output changes of distributed generators to correct the network voltages, giving priority to reactive over active power. Simulations results are presented on a 32-bus test system and three variants of the optimization problem are compared. [less ▲]

Validation d’un test d’inhibition auprès d’enfants présentant un trouble déficitaire de l’attention avec/sans hyperactivité

The objective of this study was to assess the development of inhibition in 5-11 years old children with the “Stroop fruit” task (see Archibald & Kerns, 1999; Catale & Meulemans, 2005) and to examine the clinical value of this tool. 346 French-speaking children without any developmental disorders or learning disabilities were included in this study. A clinical group of 25 children with attention deficit and hyperactivity disorder was also assessed with this task. Developmental analyses on age groups show an enhancement of performance in the interference condition between 5 and 8 years old. Furthermore, results also show that the clinical group performed significantly less accurately that the control group for the interference condition, which confirms the clinical interest of this tool.

Schmallenberg virus, a novel orthobunyavirus, is spreading among ruminants, especially sheep and cattle throughout Europe. To determine the risk for domestic dog infection, we conducted a survey among cases referred to the university Companion Animal Clinic to assess possible seroconversion. No evidence of transmission to dogs was detected. [less ▲]

An open-air site from the recent Middle Palaeolithic in the Paris Basin (France): Les Bossats at Ormesson (Seine-et-Marne).

In northern France, most of the sites attributed to the Middle Palaeolithic are open-air sites in which mainly lithic artefacts are found, due to taphonomic conditions often unfavourable to the preservation of fauna. The lithic assemblages found in most of those open-air sites suggest that the activities on the camp sites were diversified, although flint knapping was often intense due to the proximity of sources of raw siliceous materials. With the exception of very rare open-air sites, fauna is poorly preserved and spatial and economic analyses may often be based on the spatial distribution of lithic artefacts, in particular based on refits and their analysis. Therefore the palaeoethnological approach is difficult to implement in most open-air areas. In contrast, in the Paris Basin, the study of more recent sites from the Tardiglacial, such as the Magdalenian sites of Pincevent or Etiolles, falls within this approach. The recent discovery (2009) and excavation of the open-air site of Ormesson (Seine-et-Marne - France) was initially intended to document a Gravettian occupation floor dated around 26,000 years uncal BP and related to a preferential bison hunt. Whilst checking the thickness of the loess in which the Gravettian level was found, several other prehistoric settlements were discovered (Chatelperronian, Middle Solutrean) including two units attributed to the Middle Palaeolithic. One of them, level 4, seems to be particularly well-preserved. It occurs between one and three meters below the main Upper Palaeolithic occupation. The lithic industry from level 4 belongs to a technical tradition generally attributed to the Middle Palaeolithic: discoid technology. The freshness of the material and the presence of bone fragments attributed in part to horse support a general good state of preservation of this occupation. The Mousterian remains seem to cover at least 500 m2, as currently estimated. Even more exceptional is the close spatial relationship between the discoid industry, the bone pieces, remains of fireplaces and especially the numerous fragments and nodules of red colouring materials. These were brought to the site where they were utilised by the Mousterians. The used surfaces show indisputable scraping traces and facets. These recent discoveries will certainly contribute to the debate on the cognitive capacities of nearly the last representatives of the Middle Palaeolithic and this within a complex stratigraphy which will allow us to make comparisons between the different periods.

Archevêque de Rouen, cardinal, légat a latere, Georges Ier d’Amboise (1460–1510) est l’une des personnalités les plus fascinantes de la première Modernité européenne. Le prélat ne s’est toutefois pas contenté de cumuler les fonctions ecclésiastiques les plus prestigieuses. Pendant une dizaine d’années, en qualité de principal conseiller de Louis XII, il fut l’artisan de la politique royale, tant en France qu’à l’étranger. Son action concerne également les arts. Que ce soit en tant que bâtisseur et amateur averti d’architecture – comme en témoigne le château de Gaillon – ou que bibliophile et collectionneur, Georges Ier d’Amboise participe résolument à la diffusion des idées et des formes venues d’Italie. Les 2 et 3 décembre 2010 – à l’occasion du 500e anniversaire de la mort du cardinal –, un colloque international a été organisé à l’Université de Liège avec le soutien de "Transitions. Département de recherches sur le Moyen Âge tardif & la première Modernité". Les actes du colloque "Georges Ier d’Amboise (1460–1510). Une figure plurielle de la Renaissance", dirigés par Jonathan Dumont et Laure Fagnart, rassemblent la plupart des contributions présentées à ce colloque et se proposent, de la sorte, de traiter les aspects politiques, religieux et culturels de la vie du prélat, ambitionnant ainsi de faire le point sur l’état de nos connaissances, tout en dégageant de nouvelles pistes de recherches.

This paper proposes an algorithm for exploiting the localized response of power system components to accelerate dynamic simulations. During the simulation, components marginally participating to the system dynamics are characterized as latent and their dynamic models are replaced by much simpler equivalents. At the same time, components with significant dynamic activity are characterized as active and their original dynamic models are used. Based on the criterion proposed, components switch status between active and latent to increase performance while retaining accuracy. Two realistic test systems, a medium-scale and a large-scale, are used for the performance evaluation of the proposed method. [less ▲]
