This paper is part of a study investigating the prediction of aeroelastic behaviour subjected to non-linear aerodynamic forces. Of interest here is whether the sub-critical vibration behaviour of the aeroelastic model gives any information about the onset of the LCO. It would be useful to be able to use system identification methods to estimate aeroelastic models that characterise the LCO. Such a methodology would be very useful, not only for analysis with coupled CFD/FE models, but also during flight flutter testing. In this paper, the responses to initial inputs on the Goland Wing [9] CFD/FE model at different flight speeds are analysed to determine the extent of the non-linearity below the critical onset of LCO. Analysis is also performed using a linear identification model. [less ▲]

The acoustical comfort is now a comfort’s criterion which is taken into from the conception. The designers need therefore accurate tools to predict the acoustic quality of enclosures. Most of the acoustical comfort criteria are based on the reverberation time. When the room has proportionate dimensions and an uniform absorption, the statistical theory through Sabine or Eyring formulas allows good predictions of the reverberation time. Moreover, extensions of these relations by Millington or Cremer and Müller among others give quite satisfactory when the room is composed of materials with different sound absorption. In this study, the reverberation time in an enclosure is calculated via the numerical resolution of unstationary diffusion equation, model validated in coupled and industrial rooms. Firstly, an improvement of the boundary condition is proposed for highly absorbent surfaces. The diffusion model is then compared to several formulations of the statistical theory and a ray-tracing software for a cubic room with homogeneous walls’ absorption and with non homogeneous walls’ absorptions. Finally, an experimental validation is conducted for an enclosure with non uniformly distributed absorption. [less ▲]

VLTi Spectro-Imager (VSI) is a proposition for a second generation VLTI instrument which is aimed at providing the ESO community with the capability of performing image synthesis at milli-arcsecond angular resolution. VSI provides the VLTI with an instrument able to combine 4 telescopes in a baseline version and optionally up to 6 telescopes in the near-infrared spectral domain with moderate to high spectral resolution. The instrument contains its own fringe tracker in order to relax the constraints onto the VLTI infrastructure. VSI will do imaging at the milli-arcsecond scale with spectral resolution of: a) the close environments of young stars probing the initial conditions for planet formation; b) the surfaces of stars; c) the environment of evolved stars, stellar remnants and stellar winds, and d) the central region of active galactic nuclei and supermassive black holes. The science cases allowed us to specify the astrophysical requirements of the instrument and to define the necessary studies of the science group for phase A. [less ▲]

As a result of both a political and a scientific thinking, the Belgian Fund for Occupational Diseases (FOD) has launched, starting March 1st 2005, a pilot project for the nursing staff in the health care sector in order to prevent the transition of low back pain (LBP) to chronicity through a program promoting an early return to work. Target workers are those being off work due to LBP for at least 4 weeks and maximum 3 months. The program involves a standardised multidisciplinary back rehabilitation program on the one hand, and on the other hand an ergonomics intervention in the health care institution. Depending on the context, the workplace intervention may involve an ergonomic analysis with the participation of the sicklisted worker, a larger group-based ergonomics redesign, or temporary change in the worker duty or work time in order to facilitate his/her return to work. The employer gets a financial incentive from the FOD when he agrees to such an intervention. Due to a lack of communication among the target population, this pilot project has had a slow start; the presentation gives a qualitative overview of the first 100 cases having entered the program.

At the outlet of the HVCA systems, whistling can occur, due to self-sustained oscillations. In this study, the ventilation outlet is modelled by a free plane subsonic jet impinging on a slotted plate, leading to self-sustained tones production; this configuration is known as the jet-slot oscillator. The tone's frequency can be predicted through the vortex dynamics within the flow. For jet velocities higher than 16m/s, the tones couple with the flow-supply-duct’s resonances. These resonances control the vortex dynamics and reinforce the sound production, of about 20dB. Moreover, when the distance from the jet exit to the plate is increased and reaches 4.5 times the jet height, the fundamental frequency of the tones is suddenly halved due to some vortex pairing occurring at the end of the potential core of the jet. In this paper, the vortex pairing is observed with three different experimental techniques. Firstly, comparison between the radiated and the in-duct acoustic fields is conducted. Then the energy transfer from the fundamental to the sub-harmonics of the shear layer's velocity fluctuations is observed with anemometric measurements. Finally high speed flow visualizations are performed and allow to link the vortex impingement on the plate to the sound production. [less ▲]

Contradictory results were reported concerning the benefits of three-dimensional systems and new technology on surgical performance. Our study aimed to precisely evaluate perceptual and instrumental impact of new robotic technology on surgical performance and subjective impression. 60 medical students without any surgical experience were randomized into three groups (classical laparoscopy, robotic system in 3D or robotic system in 2D). After a familiarisation phase with the technique of their condition, they performed four tasks of increasing complexity and self-evaluated their performance answering a questionnaire. Finally, subjects performed the most difficult task with the technique they never used (technical switch). Our results showed significant better performance with classical laparoscopy than with robotic system in the familiarisation task. In the following tasks of increasing complexity, subjects significantly performed better, with more self-confidence, satisfaction and facility using robotic system in 3D than with classical laparoscopy. Robotic system in 2D provided significant worse results than 3D robotic system except for the last and most difficult task. Depth perception plays predominant role in easiest tasks whereas instrumental dimension is a determinant factor in performing finest tasks. Results are discussed in terms of consequences of new technology introduction for patient safety and surgeon’s training. [less ▲]

Because of the lack of clinical data in the area, this clinical study was performed to evaluate gastrointestinal prokinetics’ efficiency. Material used includes 2 groups composed each one by 25 horses which underwent surgery for small intestinal lesions in the University of Liège between january 1997 and august 2005. The 2 groups were formed by a selection resulting in similar (or not significantly different) mean values for the age, gravity score, shock score, packed cell volume on admission in the clinic and length of resected intestine when an enterectomy was performed. Between the 2 groups, we searched also equal (or not significantly different) proportions of Belgian Warmblood, of females/males, of horses wich underwent an enterectomy, of horses which had a concomitant lesion of the large intestine and of horses wich needed 1 or more sedative α2 agonist drug during the postoperative period. One group was treated with gastrointestinal prokinetics (lidocaine, erythromycin, metoclopramide) systematically, whereas the other one not and the incidence and duration of postoperative ileus was evaluated. No significant difference in the incidence or the duration of postoperative ileus was found between the 2 groups. Because our results did not show any effect of prokinetics, a statistical analysis searched in these 50 horses the risk factors of postoperative ileus among the following parameters: breed, age, sex, gravity score, shock score, packed cell volume on admission in the clinic, protocol of induction of anaesthesia, duration of anaesthesia, performing an enterectomy and length of the resected intestine, concomitant lesion of the large intestine, and administration of sedative α2 agonists during the postoperative period. Only the Belgian warmblood breed and the administration of sedative α2 agonist drugs after the recovery from anaesthesia were significantly more important in the group where horses developed a postoperative ileus. Undoubdtedly, this study includes only 50 cases selected for the homogeneity of their parameters and not all the cases of small intestine surgery during the test period. In view of these results, it would be interesting performing this study again on a larger number of cases in a prospective manner. [less ▲]

This paper presents a methodology to take into account model uncertainties related to the load-end shortening curve of stiffened panels. This method is a part of a research activity carried out at University of Liège. His goal is to propose a reliability based model to assess hull girder ultimate strength using a progressive collapse algorithm. The numerical results presented here concern the load-shortening model chosen for this research, which is based on Bureau Veritas rules. Model uncertainty is quantified as a parameter considered as a random variable. Four statistical moments (mean, standard deviation, skewness and kurtosis) of this parameter are calculated and analyzed using a data-base of stiffened panels test results published in recent years. In order to increase the number of "actual" values for the statistical assessment, the data-base is completed with non-linear finite element analysis results. The paper contains also some recommendation for the implementation of the proposed method in ultimate strength reliability based analysis. [less ▲]

In the construction market, Roll Forming is the reference forming process. Numerous parts are achieved in such a way: purlins, steeldecks or suspended ceiling parts are examples of it. Roll Forming is also more and more used in the automotive industry, as it constitutes a good alternative to forming for High Strength Steels. Among the major requirements to obtain a defect-free product are outlined: the accurate geometry of the part, the taking into account of the springback as well as the prediction of twist. Furthermore, the roll forming operation could be only the first forming operation: the part could be curved or locally deep drawn afterwards. FE codes could allow fulfilling these requirements. However, they need significant advances in terms of material model description and numerical development. This paper presents the work done in order to predict the geometry and the behaviour of a roll formed part: First the material is characterized in complex strain paths in order to identify elaborated microstructural model like Teodosiu’s one. This model is able to take into account Bauschinger effect, orthogonal strain paths, isotropic/kinematic hardening. The METAFOR code is then used to have a better understanding of the mechanics of the deformation of the strip during the forming process. Several experimental campaigns were performed on the I-R&D ARCELOR roll forming machine to define a strong database in order to validate the numerical results. The geometry of machine as well as the shape of the channels inside and outside the RF machine were measured. Some experiments were even carried out in order to generate defects like twist in the roll formed profile. [less ▲]

This study concerns the simulation of a shipbuilding workshop, and its optimization to improve its productivity. Usually, simulation is used to improve efficiency but this optimization is often done manually, particularly for shipbuilding workshop. This is due to the particularity of pieces to be manufactured: almost each of them is different and required thus particular operations. The automation is not so much present as, for example, in automotive industry. In spite of high CPU time for that kind of simulation, we will try to use optimization methods to improve productivity. Algorithm used is a genetic algorithm. [less ▲]

Studying the muscular hypertrophy of Texel sheep by forward genetics, we have identified an A-to-G transition in the 3'UTRof the GDF8 gene that reveals an illegitimate target site for microRNAs miR-1 and miR-206 that are highly expressed in skeletal muscle. This causes the down-regulation of this muscle-specific chalone and hence contributes to the muscular hypertrophyof Texel sheep. We demonstrate that polymorphisms which alter the content of putative miRNA target sites are commonin human and mice, and provide evidence that both conserved and nonconserved target sites are selectively constrained. Wespeculate that these polymorphisms might be important mediators of phenotypic variation including disease. To facilitatestudies along those lines, we have constructed a database (www.patrocles.org) listing putative polymorphic microRNA–targetinteractions. [less ▲]

Detrivorous crustaceans are pivotal components of the trophic food webs and are found to be the main constituents of the macrofauna in Posidonia oceanica litter. The coexistence of many of these species in the same biotope raises the question of trophic diversity and of its role in litter degradation process. Diet composition of five common species of detrivorous crustaceans in P. oceanica litter (i.e. the gammarid amphipods Gammarella fusicola and Gammarus aequicauda and the isopods Idotea baltica, Idotea hectica and Zenobiana prismatica) were studied using a combination of gut content and stable isotopes analysis. Despite the common food supply (i.e. Posidonia dead leaf, Posidonia epiphytes or drift macroalgae), there were considerable interspecific differences in diet composition. Gut content observations indicate that P. oceanica leaf litter is an important part of the ingested food of all the species. Algae material (macroepiphytes and drift macroalgae) inhabiting the litter is mainly found in G. fusicola, I. hectica and I. baltica. I. baltica displays a high proportion of crustacean fragments. Isotope ratios showed that most of the species do not assimilate much of the ingested Posidonia. Application of a mixing model using isotopic values to estimate the contribution of the potential different food sources confirms this view. On one hand, the tissue of G. aequicauda could be constituted by more than 50 % of P. oceanica carbon. On the other hand, for the other species studied, P. oceanica represented a minor contribution (10 - 30 %), although it is a major component of the gut contents. This could imply that micro-organism (diatoms, bacteria and fungi) living on the Posidonia detritus is a major food source of detrivorous. Moreover, I. baltica, Z. prismatica and G. fusicola have a diversified diet composed mainly of algae. Crustaceans are an important food source for I. baltica. By contrast, I. hectica indicated a major contribution of algae material. Our results demonstrate the trophic diversity existing between the detrivorous crustaceans species in P. oceanica litter. This trophic diversity is probably one of the factors that allows these species to coexist in the same biotope. The results also underline the potential role of these species in the degradation of P. oceanica litter by fragmenting mechanically the Posidonia detritus and by assimilating directly Posidonia carbon and transferring it to higher trophic level (i.e. coastal fishes). Moreover, it allows us to think that micro-organisms (diatoms, bacteria and fungi) colonising leaf litter may constitute an important food source for litter fauna. [less ▲]

Because of the morphological variation of the fossil remains, fossil species is a very difficult notion to define in palaeontology. This definition is effectively confronted to numerous problems such as body size polymorphism inside a natural population, co-existence of lineages with different morphotypes in a same species. Interestingly, paleogenetics can clarify such ambiguous situations. Size polymorphism and sexual dimorphism were particularly highly pronounced in Ursid populations. Taking as an illustration the extinct populations of brown bear in North Africa, we succeed in addressing the mitochondrial genetic diversity of these Atlas bears and the sexual dimorphism of these samples using molecular typing We are confident that these results will give useful information to palaeontologists in order to revisit the Atlas bears taxonomy and that this approach should be extended to other complex cases of palaeontological species.

The dynamic performance of complex mechanisms, such as machine tools, manipulators, vehicles, engines or foldable structures, can be strongly affected by flexible phenomena. Therefore, the deformation effects should be considered as soon as possible in the design procedure, which motivates the development of automatic optimization techniques for flexible multibody systems. Advanced software tools are able to simulate the dynamic behaviour of such systems, but they typically involve extensive numerical treatments. Hence, gradient-based optimization methods are of special interest since they require a quite low number of simulations, but an important problem is to obtain the sensitivities of the objective function with respect to the design parameters. Since finite difference approaches lack robustness and computational efficiency, we propose to investigate analytical or semi-analytical sensitivity analysis. Several difficulties are inherent to the simulation of flexible mechanisms. A consistent geometric formulation is necessary to describe large amplitude motion as well as possible large deformations. Here, according to the nonlinear finite element formulation, the motion is parameterized using absolute nodal coordinates, and an updated Lagrangian point of view is adopted for the rotation parameters. The joints and the rigid-body conditions are represented by algebraic constraints between the nodal coordinates, leading to differential algebraic equations of motion (DAEs). Finally, the computation of the trajectories requires a reliable simulation algorithm for nonlinear DAEs. A strong advantage of the finite element method comes from its very systematic implementation, which facilitates the development of a semi-analytical sensitivity analysis. In this work, sensitivity analysis is performed for beam elements, rigid bodies and ideal joints. The global sensitivity is then obtained by numerical assembly of the elementary contributions and by integration in the time domain. Thus, a single but extended simulation is sufficient to compute the sensitivities with respect to all parameters. In order to illustrate the method and to demonstrate its efficiency, we consider the optimal design of a car engine, where the flexibility of the connecting rods between the crankshaft and the pistons is taken into account. The objective is to find a feasible mechanical design which minimizes the level of vibrations. [less ▲]

A general model is proposed to simulate the acoustics of coupled rooms. It is based on a diffusion equation, solved numerically to perform acoustic predictions. The presence of scattering objects –or the “fittings”– is also taken into account. Distinct sub-volumes can be defined, representing either coupled volumes or zones with different fitting characteristics. Some sample results are presented, and compared with ray-tracing results and experimental data. Two situations are assessed: two coupled classrooms, and a room divided into two zones, one empty, one fitted. The diffusion-model predictions match the other data satisfactorily, both in terms of sound attenuation and sound decay. Diffusion-based results are obtained with the advantage of low computational time compared to ray-tracing results. [less ▲]
