The goal of this study is to apply a “multisite” crystal plasticity model to the prediction of texture evolution in zirconium deformed at high temperature. The model under consideration is an extension of the elastic-viscoplastic “multisite model” proposed by Delannay et al. [2005] which has been adapted to account for a new type of grain interaction (Van Houtte et al. [2005]). Predictions of the model are compared to experimental data. Two forming processes are considered: sheet rolling (Lebensohn et al. [1994]) and the torsion of a cylindrical bar (Sanchez et al. [2001]). [less ▲]

In this paper we present a new tree-based ensemble method called “Extra-Trees”. This algorithm averages predictions of trees obtained by partitioning the inputspace with randomly generated splits, leading to significant improvements of precision, and various algorithmic advantages, in particular reduced computational complexity and scalability. We also discuss two generic applications of this algorithm, namely for time-series classification and for the automatic inference of near-optimal sequential decision policies from experimental data.

Stochastic simulation of aquifer heterogeneity is now often performed to provide a confidence interval of the modelled results for flow and solute transport problems. In practice, due to the few available measurements of the hydraulic conductivity (hard data), it is useful to integrate several other properties of the medium as indirect data (soft data). The additional conditioning obtained from the use of these secondary data allows reduction of the variance of the distribution and consequently decrease of the uncertainty of the results. This practice can also be extended to low permeability clay layers. For example, stochastic sequential simulation can be performed involving hydraulic conductivity values as hard data, and grain size measurements, electrical resistivity log, gamma ray log and a description of the lithology variation as soft data. However, other important properties can also be considered. The possible fracturing of clay strongly influences the flow and solute transport. On the other hand, in very low permeability media, diffusion can be considered as the dominant transport mechanism, so that heterogeneity in terms of the effective diffusion coefficient becomes important. Examples of application are summarized considering aquifers and low permeability clay layers. It clearly shows the great advantage of collecting multiple data sets of inter-correlated data on the same geological medium to be modelled. In high conductivity aquifers as well as in low permeability layers, this kind of additional conditioning obtained from various data is always useful when considering applications such as, among many others, well capture zones delineation, impact studies and geological confinement of wastes.

We present our recent results on using previously introduced framework for multi-area security assessment in large interconnections. The basic idea of the framework is exchanging just enough information so that each operator can evaluate the impact in his control area of contingencies both internal and external to his area. We provide illustrations based on a localization concept known as efficient bounding method and recently introduced approximate DC model of the European interconnected system. In this paper we focus on four transmission system operators (within the approximate DC model): Belgium, France, Germany, and Netherlands (for both Summer and Winter-peak load conditions). [less ▲]

Senecio inaequidens DC. was introduced from South Africa to Europe more than one hundred years ago, in a few precise locations linked to wool industry and extended its distribution throughout Europe. In a context of global warming, the potential evolution in germination and growth during the invasion process was studied in relation to altitude and climate. Seeds were collected along two transects (both altitudinal and climatic) in Belgium and France, going from the sea level to high altitudes (respectively 485 m and 1700 m) through the introduction spots. Respectively four and five climatic zones per transect, two populations per zone and ten randomly selected individuals per population were sampled. Seeds were sorted in order to discard maternal effects. Ten seeds per parent individual were thereafter sown in pots in a common garden experiment in Gembloux (Belgium). Germination was checked every two days. Height and diameter of plants, enabling the calculation of plant volume, were measured every 25 days. Despite an important variability, linear regression of first germination time (since sowing) vs altitude was significant (p = 0.001) for the French gradient, but not for the Belgian one. No significant difference was found in germination rate between climatic zones. For each of the three measurement times of plant height and diameter, regression of plant volume vs altitude was also significant for the French transect (p varying from 0.025 to 0.000 according to time), but not for the Belgian one. French plants from elevated locations germinated later and grow slowlier. These preliminary results suggest that contrasted climatic conditions in the French gradient, going from the Mediterranean coast to the Pyrrenean high elevations led to genetic differenciation of Senecio populations during its invasion in southern France. Less contrasted climatic conditions, together with a supposed loss of genetic variability (Lafuma 2003), did not lead to a clear differenciation in Belgium. References : Lafuma, L. (2003).

It has been shown previously that some categories of stimuli are more likely to capture attention under condition of inattention compared to others. This is the case of faces and auto-referential material (e.g., the subject’s own name) in the inattentional blindness paradigm (Mack & Rock, 1998). However, stimuli combining these two properties have never been assessed. Yet it could be that the own face, because it is both a face and a self-referential stimulus, is more prone to attract attention compared to other faces. On the contrary, it could be that the identity and the familiarity of faces are not relevant factors because any face attracts attention by itself and all faces are equally distractive. Moreover, most of previous studies have used schematic unrealistic stimuli. Here, we tested these two opposite hypotheses in a first experiment using photographic stimuli and results showed that the own face does not attract attention compared to another highly familiar face or to an unknown face. Nevertheless, it appears that the own face was still better recognized compared to the others. A second experiment was aimed at verifying whether faces attract attention more than other objects with the same realistic photographic stimuli than used in experiment 1. Results confirmed previous findings that faces are more resistant to inattentional blindness than other objects. Our study suggests that a face by itself attracts attention compared to other objects whatever its familiarity or its identity. These results challenge the view that auto-referential material benefits from specific attentional processes. [less ▲]

A generic method for supervised classification of structured objects is presented. The approach induces a classifier by (i) deriving a surrogate dataset from a pre-classified dataset of structured objects, by segmenting them into pieces, (ii) learning a model relating pieces to object-classes, (iii) classifying structured objects by combining predictions made for their pieces. The segmentation allows to exploit local information and can be adapted to inject invariances into the resulting classifier. The framework is illustrated on practical sequence, time-series and image classification problems. [less ▲]

We extend tree-based methods to the prediction of structured outputs using a kernelization of the algorithm that allows one to grow trees as soon as a kernel can be defined on the output space. The resulting algorithm, called output kernel trees (OK3), generalizes classification and regression trees as well as tree-based ensemble methods in a principled way. It inherits several features of these methods such as interpretability, robustness to irrelevant variables, and input scalability. When only the Gram matrix over the outputs of the learning sample is given, it learns the output kernel as a function of inputs. We show that the proposed algorithm works well on an image reconstruction task and on a biological network inference problem. [less ▲]

Among natural factors driving the soil content in metallic trace elements (MTE), the geochemical background is often deemed as a sound base for the detection of contaminations. Numerous studies have shown the difficulties to take into account the multi-dimensionnality of the spatial variability of most soil properties. As far as a detailed soil map is available for Belgium, the relevance of its information was investigated at various spatial scales in the Walloon Region (Southern Belgium), from the plot to the entire region, to evaluate the feasibility of a multi-scale mapping of geochemical background. A database of soil profiles (gathering both agricultural and forest soils) was used to analyse the relationships between the MTE total content (measured after HF-HClO4-HCl dissolution) and other general characteristics such as pH, Total Organic Carbon content (TOC), Particle Size Distribution (PSD), and cationic exchange capacity (CEC). The factors of MTE spatial distribution inside and between solums were investigated through multivariate statistical analysis. The spatial dependence of these factors was then studied over plot, field, farm, county and region scales, and compared to the spatial structures of the soil map parameters. At the solum level, strong relationships between most of the studied MTE were found, as well as between stone charge and fine earth contents. The PSD is the main driving factor of MTE content in non-carbonated soils, whatever the land use. When considering soil associations, such as catenas, the slope redistribution processes must be taken into account. However, the PSD remains the main driving factors and, as the soil map contains information about that property (mainly the textural class and the profile development), a cartography of the geochemical background based on the use of the soil map and pedotransfer functions or regression models appears relevant. At the regional scale, some long-range spatial structures could be identified. These result mainly from the geological structure of the Walloon region, where the lithological zonation is rather clearly marked. The soil map (texture and nature of stone charge) appears relevant at that scale too but does need a generalization process and fails however to differenciate the intra-type soil spatial variability. Some basic processes of integration of point measurements and qualitative information have been explored. They should be further investigated in the future. [less ▲]

The space mission PEGASE, proposed to the CNES (Centre National d'Etudes Spatiales = French Space Agency) in the framework of its call for scientific proposals : "formation flying missions", is a 2-aperture interferometer, composed by 3 free flying satellites (2 siderostats and 1 beam combiner), allowing baselines from 50 to 500 m in both nulling and visibility modes. With an angular resolution of a few mas and a spectral resolution of several tens in the spectral range 2.5-5 microns, PEGASE has several goals:science : spectroscopy of hot jupiters (Pegasides) and brown dwarves, exploration of the inner part of protoplanetary diskstechnology : validation in real space conditions of formation flying, nulling and visibility interferometry concepts.PEGASE has been studied at a 0-level. In this paper, we summarize the scientific program and associated technological and mission trade-off coming from this 0-level study. We also discuss how PEGASE can be considered as a TPF/DARWIN pathfinder in an international roadmap towards more complex space interferometry missions such as DARWIN/TPF. [less ▲]
