The unsteady Vortex Lattice method is becoming an increasingly popular aerodynamic modelling method for incompressible aeroelastic problems, such as flexible low-speed aircraft, wind turbines and flapping flight. It leads to discrete time aeroelastic state space equations, which must be solved in a time-marching framework. Eigenvalue or singular value decompositions of the discrete time equations can be used in order to perform stability analysis but such procedures must be accompanied by model order reduction because the size of the equations is large. This work proposes a modal frequency domain implementation of the Vortex Lattice method, resulting in a modal generalised force matrix. Model order reduction is implicit in the modal approach and stability analysis can be carried out using industry-standard flutter analysis techniques, such as the p-k method. The approach is validated by comparison to wind tunnel flutter data obtained from rectangular cantilever flat plate wings of different aspect ratios and sweep angles. It is found that the aeroelastic model predictions follow the experimental trends for both flutter speed and frequency but tend to be moderately conservative. [less ▲]

Ce travail vient synthétiser l’ouvrage Narration et jeu vidéo. Pour une exploration des univers fictionnels (Liège, Bebooks, 2014), lui-même dédié à l’étude des différentes modalités via lesquelles le médium vidéoludique peut représenter une histoire. En se basant sur l’analyse de deux oppositions épistémologiques qui ont agité le champ des sciences du jeu au début des années 2000 (celle entre ludologues et narratologues, d’une part, et celle entre game studies et play studies, d’autre part), cet article défend l’idée que les outils narratologiques traditionnels ne sont pas aptes à rendre compte de la narrativité du jeu vidéo sous tous ses aspects, car celle-ci ne se limite pas à un récit strictement linéaire et unidimensionnel : les informations narratives peuvent être portées par des éléments proprement ludiques (les décors, l’interface, le gameplay…) qui, en outre, peuvent être actualisés de différentes manières par les joueurs. Fonder l’analyse narratologique du jeu vidéo sur la notion de récit semble dès lors réducteur puisque celle-ci ne permet pas de décrire la narrativité latente propre au médium ni l’influence qu’exerce le joueur sur son activation. En réponse à ces problèmes théoriques, cette étude propose donc de substituer au concept de récit celui, plus opératoire, d’univers fictionnel. [less ▲]

The present work is a comparative analysis of Proper Orthogonal Decomposition (POD) and Dynamic Mode Decomposition (DMD) computed on experimental turbulent velocity fields measured in a 20L-tank stirred by two Rushton impellers at two rotating speeds, N = 150 and 300 rpm. POD identifies flow structures that optimally capture the total kinetic energy of the flow, while DMD identifies structures that significantly contribute to the dynamics of the flow. The experimental data, i.e. the instantaneous radial and axial velocity fields, come from 2-D Particle Image Velocimetry (PIV). The flow motion is turbulent, and it occurs over a wide range of length and time scales, from equipment-dependent large-scale coherent structures to the smallest-scale eddies where energy dissipation takes place. It thus provides an interesting benchmark case for the comparison between POD and DMD, which are based on energy and dynamic analysis, respectively. POD analysis reveals that the most energetic structures are related to the inherent periodic unsteadiness due to the relative motion between the rotating impeller blades and the non-moving baffles. Apart from the mean field, the first most energetic group of modes is related to trailing vortices induced by the Rushton turbines and is associated to a frequency equivalent to the blade passage frequency and its overtones. The second most energetic group of modes is related to vortical structures in the impeller stream and is associated to a frequency equivalent to the rotating speed. DMD analysis identifies flow structures that are found similar to these most energetic modes, although differences appear due to the fact that DMD isolates structures associated to a single frequency and their corresponding growth/decay rate. As in POD, the relative importance of each DMD mode can be estimated using an appropriately defined energy criterion. Comparison of the results from both modal decomposition methods points out their complementarity and their potential for describing the spatial and time characteristics of the flow within a stirred tank.

The contribution focuses on small objects such as portable altars, small bases, vessel, stone plaques and blocks inscribed with dedications for rulers in an attempt to provide an in-depth analysis of a type of material that has often been neglected or underexploited, because of its serial nature and the poor textual information it bears. By combining material analysis of scripture and support with archaeological data (when available), the paper aims 1) to set the evidence back in a dynamic historical context and 2) to provide a methodological reflection on the way we can deal with an abundant but often underestimated evidence. The risk for generalization inherent in the treatment of many uncharacterized stones as “altars” emerges from a reassessment of the Cypriot documentation for Ptolemaic rulers. Moreover, Ptolemaic and Attalid case studies allows for a reflection on the role of small ritual objects in the dissemination of ruler cult across social strata and in the integration of cultic honours for rulers in the ritual landscape of the studied communities, in public as in private space, in sanctuaries as along the city streets.

Rasa3 is a GTPase activating protein of the GAP1 family which targets R-Ras and Rap1. Although catalytic inactivation or deletion of Rasa3 in mice leads to severe hemorrhages and embryonic lethality, the biological function and cellular location of Rasa3 underlying these defects remains unknown. Here, using a combination of loss of function studies in mouse and zebrafish as well as in vitro cell biology approaches, we identify a key role for Rasa3 in endothelial cells and vascular lumen integrity. Specific ablation of Rasa3 in the mouse endothelium, but not in megakaryocytes and platelets, lead to embryonic bleeding and death at mid-gestation, recapitulating the phenotype observed in full Rasa3 knock-out mice. Reduced plexus/sprouts formation and vascular lumenization defects were observed when Rasa3 was specifically inactivated in mouse endothelial cells at the postnatal or adult stages. Similar results were obtained in zebrafish after decreasing Rasa3 expression. In vitro, depletion of Rasa3 in cultured endothelial cells increased β1 integrin activation and cell adhesion to extracellular matrix components, decreased cell migration and blocked tubulogenesis. During migration, these Rasa3-depleted cells exhibited larger and more mature adhesions resulting from a perturbed dynamics of adhesion assembly and disassembly which significantly increased their life time. These defects were due to a hyperactivation of the Rap1 GTPase and blockade of FAK/Src signaling. Finally, Rasa3-depleted cells showed reduced turnover of VE-cadherin-based adhesions resulting in more stable endothelial cell-cell adhesion and decreased endothelial permeability. Altogether, our results indicate that Rasa3 is a critical regulator of Rap1 in endothelial cells which controls adhesions properties and vascular lumen integrity; its specific endothelial cell inactivation results in occluded blood vessels, hemorrhages and early embryonic death in mouse, mimicking thus the Rasa3-/- mouse phenotype.

Belgium is characterised by a wide variety of rocks, including carbonate formations, which are significantly represented in eastern Belgium. Among those formations, Devonian and Carboniferous carbonates display the most developed karstic features, as illustrated by the two cave systems presented in this chapter. Although both systems are water caves, they differ in many ways. The Remouchamps Cave, developed in the Upper Devonian limestones, is a touristic cave, while the Noû Bleû Cave, developed in the Carboniferous carbonates, is a brand new discovery still under exploration. The two systems are of scientific interest and contain many deposits (speleothems and detrital sediments) providing records of past environmental changes and paleoclimates. Beside the Quaternary dynamics, the present-day dynamics can be highlighted within the karstic basins that encompass the two cave systems. The generation or reactivation of sinkholes and swallow holes is often favoured or triggered by human activity. Furthermore, the two basins offer several good examples of human interaction with karst environments, not only in terms of karstic constraints for humans but also as a resource that must be preserved.
