In this paper, the modifications that have been recently introduced in the parametric fire model of Eurocode 1 are presented. The reasons behind these modifications are given. Some Problems that have been discovered in the present formulation are highlighted, namely the fact that the model is not continuous and the fact that the heat release of wood that has been used for the calibration of the model is not consistent anymore with the value that is now recommended in the Eurocode. A proposal is made that makes the model continuous. A new calibration of this modified model has been made on the base of the now recommended value of the heat release of wood with comparison to the results of some 50 full scale experimental fire tests.

The European Space Agency's Darwin and NASA's Terrestrial Planet Finder (TPF) are among the most challenging space science missions ever considered. Their principal objective is to detect Earth-like planets around nearby stars and to characterize their atmospheres. Darwin and TPF-I are currently conceived as nulling interferometers with free-flying telescopes. Within the frame of the Darwin program, the ESA and the European Southern Observatory (ESO), supported by European industries and scientific institutes, have performed two parallel Phase A studies of a ground-based nulling interferometry experiment (GENIE) at the site of ESO's Very Large Telescope Interferometer (VLTI) in Paranal, Chile. GENIE will demonstrate several key technologies required for the Darwin mission. Its science objectives include the detection and characterization of dust disks and low-mass companions around nearby stars. These studies have established detailed instrumental designs, in which GENIE will operate in the L' band around 3.8 microns as a single Bracewell nulling or constructive interferometer, using either two Auxiliary or two Unit Telescopes. The studies were supported by detailed numerical simulations which indicated the possibility of detection and low-resolution spectroscopy in nulling mode of extra-solar giant planets (EGPs) with atmospheric temperatures down to 700 K, provided that a proper calibration of instrumental effects is applied. Detection of circumstellar exo-zodiacal (EZ) dust clouds is possible down to 0.5 mJy, with interesting prospects for the characterization of planet-forming disks. [less ▲]

Multiple cameras and collaboration between them make possible the integration of information available from multiple views and reduce the uncertainty due to occlusions. This paper presents a novel method for integrating and tracking multi-view observations using bidirectional belief propagation. The method is based on a fully connected graphical model where target states at different views are represented as different but correlated random variables, and image observations at a given view are only associated with the target states at the same view. The tracking processes at different views collaborate with each other by exchanging information using a message passing scheme, which largely avoids propagating wrong information. An efficient sequential belief propagation algorithm is adopted to perform the collaboration and to infer the multi-view target states. We demonstrate the effectiveness of our method on video-surveillance sequences. [less ▲]

The study of adhesion of repair materials on concrete structures implies a good knowledge of the influence of concrete surface treatment. The effects of surface preparation technique is rarely clearly described and parameterised: it is consequently difficult to point out the real influence of roughness on adhesion results. A first step was made by using mechanical profilometry to differentiate concrete surfaces prepared by shot blasting, sand blasting and hand or mechanical milling. This technique is very accurate for investigations in laboratory, on a limited surface area. If Quality Control is requested or if it is impossible to core samples from the site, other procedures should be followed. That the reason why opto-morphometry analysis has been developed, in order to analyse larger surfaces. The comparison of the two techniques shows clearly the advan-tages of each one and the precision that can be achieved. [less ▲]

In order to compute the reachability set of infinite-state models, one needs a technique for exploring infinite sequences of transitions in finite time, as well as a symbolic representation for the finite and infinite sets of configurations that are to be handled. The representation problem can be solved by automata-based methods, which consist in representing a set by a finite-state machine recognizing its elements, suitably encoded as words over a finite alphabet. Automata-based set representations have many advantages: They are expressive, easy to manipulate, and admit a canonical form. In this survey, we describe two automata-based structures that have been developed for representing sets of numbers (or, more generally, of vectors): The Number Decision Diagram (NDD) for integer values, and the Real Vector Automaton (RVA) for real numbers. We discuss the expressiveness of these structures, present some construction algorithms, and give a brief introduction to some related acceleration techniques. [less ▲]

The Hilbert-Huang transform (HHT) has been shown to be effective for characterizing a wide range of nonstationary signals in terms of elemental components through what has been called the empirical mode decomposition. The HHT has been utilized extensively despite the absence of a serious analytical foundation, as it provides a concise basis for the analysis of strongly nonlinear systems. In this paper, we attempt to provide the missing link, showing the relationship between the EMD and the slow-flow equations of the system. The slow-flow model is established by performing a partition between slow and fast dynamics using the complexification-averaging technique, and a dynamical system described by slowly-varying amplitudes and phases is obtained. These variables can also be extracted directly from the experimental measurements using the Hilbert transform coupled with the EMD. The comparison between the experimental and analytical results forms the basis of a nonlinear system identification method, termed the slow-flow model identification method, which is demonstrated using numerical examples.

When resorting to numerical algorithms, we show that nonlinear normal mode (NNM) computation is possible with limited implementation effort, which paves the way to a practical method for determining the NNMs of nonlinear mechanical systems. The proposed method relies on two main techniques, namely a shooting procedure and a method for the continuation of NNM motions. In addition, sensitivity analysis is used to reduce the computational burden of the algorithm. A simplified discrete model of a nonlinear bladed disk is considered to demonstrate the developments.

The total concentrations of trace elements in soils results from natural and anthropic factors. Knowledge of natural distribution (e.g. bio-geochemical background) helps assessing the impacts of human activities in terms of contaminations. But the processes generated by the modifications of the soil environment may also affect the form of a trace element, that is its distribution through various pools. We investigated the chemical speciation of some metallic trace elements (Cu, Zn, Cr, Ni, Pb, Co, Cd) in soils from various land-use environment: “natural” soils under forest, “typical” cultivated soils, kitchen-garden soils, soils developped on geogenic anomalies and on contaminated areas. The analysis protocol aims at identifying different pools from their reaction to various extraction phases, ordered by increasing intensity in a single sequence. The different fractions are so-called soluble, linked to carbonates, to organic matter, to manganese oxides, to weakly cristallized Fe-Al oxides, to well-cristallized oxides, and residual. The “available” and total fractions have also been measured. The results stress the fact that the comparisons are difficult from one situation to another because each one represents a particular case of human activity without a common logic. The relationships with the classical pedological parameters are therefore difficult to generalize. However some relationships between elements have been found inside the various types of land use, which could be usefull in the risk assesment of transfers from soils to plants. [less ▲]

After an initial positive response to anti-androgen treatment, prostate cancer (PCa) cells usually become hormone-refractory in spite of their persistent expression of the androgen receptor (AR). Overexpression of tyrosine kinase receptors in androgen-deprived PCa cells, such as those of the EGF receptor (EGFR) family, may be responsible for AR activation and growth of androgen-deprived tumours. Our goal is to understand the control of the expression of the EGFR family members by androgens in PCa. Hormone response was compared in hormone-sensitive LNCaP and hormone-insensitive DU145 PCa cell lines. These cells do not express ErbB4. EGFR, erbB2 and erbB3 protein half-life is much longer in DU145 than in LNCaP cells grown in complete medium. Dihydrotestosterone (DHT) modulates EGFR and erbB2 transcript and protein levels only in LNCaP cells. ErbB3 is not an androgen-responsive gene. EGFR mRNA and protein levels are increased while erbB2 mRNA and protein levels are decreased after DHT treatment of cells cultured in steroid-deprived medium. ErbB2 mRNA and protein levels are increased in LNCaP cells following DHT withdrawal. In order to understand the mechanisms by which androgens control the expression of EGFR and ERBB2 genes, half lifes of the corresponding mRNAs and proteins were compared in cells grown in presence or absence of DHT. The effect of DHT on EGFR gene expression is complex. Indeed, DHT stabilizes the protein. Moreover, a superinduction of EGFR mRNA was observed in cells treated with cycloheximide (CHX) before addition of the hormone, suggesting an effect on transcript stability. In contrast, erbB2 mRNA and protein stability was not affected by DHT. CHX treatment for 2h before addition of DHT suppresses the androgen-induced down-regulation of erbB2 mRNA levels. In summary, androgen-mediated regulation of EGFR and ERBB2 genes expression is complex. DHT influences EGFR gene transcription, mRNA and protein stability. DHT does not affect erbB2 mRNA and protein stability but acts indirectly on transcription. Current experiments are undertaken to verify these observations by Chromatin-IP experiments on both genes promoters. [less ▲]

This paper presents results ofanumerical study onreinforced concrete and fully encased composite columns designed according to the “Inerd” concept aiming at obviating the soft storey mechanism in frames subjected to earthquake. The model uses fibre beam elements with mono-axial non linear material laws for concrete, steel and reinforcing steel. The crushing of concrete in compression and the cracking in tension are taken into account. The steel behaviour is elastic-plastic with strain hardening. After calibration of the model against experimental results, a parametric study is performed. The main objective is to generate the cyclic moment-rotation curves of the columns under different level of axial forces and with different proper-ties of concrete and then to deduce ductility and rotation capacity of the composite sections from these curves.

Introduction : Le seuil de sensibilité à la douleur (SSD) peut être apprécié à partir de la pression minimale induisant une perception nociceptive. Ce seuil s’objective aisément en pratique clinique par une mesure dolorimétrique. Le but de ce travail consiste à comparer, à partir d’une mesure dolorimétrique, le SSD de sujets contrôles et fibromyalgiques et, d’autre part, d’établir des valeurs normatives. Patients et méthodes : Cent sujets contrôles (50 féminins et 50 masculins) et 20 patientes fibromyalgiques sont inclus dans l’étude. Le SSD des 18 points sensibles définis par le Collège Américain de Rhumatologie dans le cadre des critères de classification de la fibromyalgie est mesuré à partir d’un dolorimètre électronique. La pression transmise est augmentée graduellement au rythme de 1 kg/cm² chaque seconde et ce, jusqu’à l’apparition d’une véritable douleur, et non plus d’une simple sensibilité. Le SSD (en kg/cm²) des 9 points spécifiques bilatéraux est déterminé et un score myalgique s’établit par l’addition de ceux-ci. Un test-retest réalisé à 3 jours d’intervalle apprécie la reproductibilité intra-examinateur des SSD. Résultats : Les coefficients de variation correspondent respectivement à 17 % et 13 % chez les sujets contrôles féminins et masculins, et 24 % chez les fibromyalgiques. La reproductibilité apparaît la plus favorable pour les points « fessier » et « genou ». Les SSD s’avèrent significativement inférieurs chez les sujets contrôles féminins en comparaison des volontaires masculins (p < 0,01) et aucun effet de latéralité n’est constaté. Les SSD mesurés chez les fibromyalgiques demeurent systématiquement inférieurs (réduction de 60 %) à ceux de la population contrôle (p < 0,0001). Les SSD les plus faibles sont mesurés aux points « trapèze », « occiput », « cervical antérieur » et « 2ème côte » tant chez les sujets contrôles que fibromyalgiques. Le score myalgique atteint 20 + 7,4 kg/cm² et 49,9 kg/cm² respectivement chez les patients fibromyalgiques et chez les sujets contrôles féminins. Discussion : Une mesure dolorimétrique permet d’objectiver le SSD avec une reproductibilité satisfaisante. Ce travail démontre des valeurs de SSD particulièrement faibles chez les fibromyalgiques. De façon originale, nous objectivons, chez les sujets contrôles, particulièrement de sexe féminin, des SSD souvent inférieurs au seuil décrit par l’ACR (4 kg/cm²). Conclusion : L’établissement d’un score myalgique permet d’apprécier, à partir d’une mesure dolorimétrique, la sensibilité nociceptive et offre la possibilité d’un suivi longitudinal du patient en terme de douleur.

In the family Pomacentridae, six genera were reported as sound producers: Amphiprion, Dascyllus, Stegastes, Chromis, Abudefduf and Plectroglyphidodon. The anemonefishes (Amphiprioninae) live in social group in association with sea anemones, which protect them from predators. Their sound emissions seem involved in courtship and territorial defense, contributing to both survival and reproductive success. However, the mechanism of sound production is unresolved. It has been hypothesized that it involves swimbladder or the action of the pharyngeal jaws amplified by swimbladder. The aim of this study was to understand the sonic mechanism involved in the agonistic sounds in Amphiprion clarkii. The approach consists in high-speed cineradiography and functional morphology. During agonistic sounds (pops), fishes perform different movements such as skull elevation, pectoral girdle retraction, hyoid lowering and mouth closing. Pops are produced when the hyoid is completely lowered and the mouth closed. The simultaneous realization of these movements was never observed in teleost. In Amphiprion sp., it is possible due to an additional ligament inserted on the hyoid bar and on the inner lower jaw. The hyoid lowering combined to the closing (and thus the elevation) of the mandible could generate a tension of the ligament, provoking its vibration [less ▲]

Poly(epsilon-caprolactone) foams were prepared, via a batch process, by using supercritical CO(2) as foaming agent. Their porous structure was characterized through helium and mercury pycnometry, scanning electron microscopy (SEM) and X-ray microtomography observations coupled with image analysis. The pore size distributions obtained by these two latter techniques show that the pore structure is more homogeneous when the foaming process is performed under a high CO(2) saturation pressure (higher than 250 bars).

In the global framework of river management, sedimentation problems in dam reservoirs and adjacent structures are multiple and of major interest for designers as well as dam owners or managers. Before dam construction, these problems can be assessed by several techniques. In this paper, the experimental and numerical sedimentation studies realized at the Laboratory of Applied Hydrodynamics and Hydraulic Constructions (HACH) of the University of Liège on a large hydropower plant project in India are presented. Three main issues related to sedimentation problems are analyzed in details. [less ▲]

The present paper first describes briefly the hydrodynamic model WOLF 2D. Secondly, the simulation of the Malpasset dam break enables to highlight the effectiveness of WOLF 2D. Lastly, the model is applied to simulate the flood generated by the hypothetic collapse of a large concrete dam, which would induce three dam breaks in cascade. [less ▲]

The aim of this paper is to validate numerical simula- tions of electromechanical coupling in micro-structures using some experimental results. The micro-structures studied here consist in a micro-bridge and two cantilever micro-beams. Multi-physics models of micro-electro- mechanical systems (MEMS) based on the ¯nite ele- ment method (FEM) are used to model the strongly coupled electro-mechanical interactions and to perform static analyses taking into account large displacements. In all the cases treated here the numerical results are in very good agreement with the experimental results. [less ▲]

In the framework of a Euratom research program devoted to Nuclear Waste deposition security assessment, a numerical simulation of the excavation of a gallery in the Boom Clay layer at Mol (Belgium) has been performed In order to model the progressive excavation and lining installation process, a special sequence of desactivation/activation of sets of elements was elaborated. In particular, this numerical strategy allowed to take into account the fact that, due to the deformation of the massif as the excavation progresses, the material to be excavated once the front has reached a given position into the rock mass cannot be defined a priori, but is resulting of the modelling of the previous phases up to the present one.
