Lors d’une recherche sur la construction de supports pour l’étude des élèves (de 15 à 18 ans) par des futurs enseignants de sciences en formation initiale (Poffé, Laschet & Hindryckx, 2015a et c) les chercheurs formateurs ont remarqué que ces derniers illustraient les notions enseignées par de nombreuses représentations graphiques. Au travers de l’analyse de 215 périodes d’enseignement accompagnées de leurs supports pour l’étude, le but de la recherche était de mettre en évidence les difficultés et donc les inégalités d’apprentissage potentielles engendrées par ces supports et leur contenu qui doivent pourtant servir à l’apprentissage et à l’étude des élèves (Bautier & Rayou, 2009 ; Beckers, Crinon & Simons, 2012). À la suite de cette recherche, un module de formation dédié à la confection de supports efficaces pour l’apprentissage et l’étude a été mis en place dans le cadre de la formation initiale des futurs enseignants du secondaire supérieur en sciences biologiques en fédération Wallonie-Bruxelles (Belgique) (Poffé, Laschet & Hindryckx, 2015b). Ce module consiste en une analyse d’extraits choisis de supports pour l’étude conçus par les futurs enseignants qui avaient fait l’objet de la recherche, pour en identifier les points forts et les points faibles pouvant mener à des inégalités d’apprentissage. Ensuite, une liste des points d’attention pour réaliser des supports pour l’étude est dressée avec les futurs enseignants. Cette recherche n’avait pas mené d’investigations du côté des élèves, de leurs difficultés réelles et de l’effet de ces supports sur leurs apprentissages. Les chercheurs formateurs ont voulu alors aller plus loin et tester l’influence du type de supports proposés à des élèves à propos d’un sujet scientifique déterminé, sur le choix du type de support, mais également sur leurs apprentissages (Lebrun, Lacelle & Boutin, 2012). À cette fin, 116 élèves de cinq classes de cinquième et de sixième secondaire (16-17 et 17-18 ans), avec trois ou six périodes de sciences par semaine, ont été soumis à une séquence didactique particulière décrite ci-dessous (Slomian, 2019). Le thème choisi pour la séquence fait partie des apprentissages à mettre en œuvre au cycle supérieur (15 à 18 ans) dans le domaine de l’environnement : l’impact de l’homme sur les écosystèmes (Ministère FWB, 2014, p. 34). L’intention des chercheurs, en plus de tester l’efficacité d’un type de support, était dans le même temps d’établir un premier contact pour des jeunes de cet âge avec la recherche en sciences ainsi que le monde des chercheurs, suscitant éventuellement des orientations de ces élèves vers des études supérieures dans le domaine scientifique. En effet, Legendre (2012) et Pronovost, Cormier, Potvin & Riopel (2017) ont constatés que de moins en moins de jeunes se dirigent vers des métiers et donc des études à tendance scientifique. Les chercheurs ont donc choisi de travailler des concepts relevant de l’impact de l’homme sur les écosystèmes et de sensibiliser les élèves au métier de chercheur en partant d’un véritable article de recherche récent (Collard et al., 2017) qui serait adapté sous différentes formes d’écrits et présenté aux élèves pour apprendre les notions abordées. Une spécialiste de la vulgarisation scientifique à partir d’articles de recherches réalisées à l’Université de Liège dans le domaine des sciences, a veillé à la transposition de l’article rédigé en anglais en trois formes accessibles à des élèves de cet âge (Davis & Russ, 2015 ; Verhaegen, 1990 ; Britton, Glynn, Meyer & Penland, 1982). Ainsi, ces derniers avaient le choix entre une présentation sous une forme évoquant une bande dessinée, une carte conceptuelle détaillant la problématique par mots clés et un texte continu illustré par des images représentatives des notions décrites. Ces documents seront présentés lors de l’intervention au colloque. La séquence prévue durait deux périodes de 50 minutes, groupées ou non. La première partie consistait en un pré-test ciblant les habitudes des élèves partenaires en termes de lecture ; leur profil d’apprentissage ; leurs goût envers les sciences, ainsi que leurs connaissances générales à propos de problèmes environnementaux (Lafontaine, Crépin, Quittre, 2017). Ensuite, les élèves ont pu faire connaissance, par l’intermédiaire d’une courte vidéo, avec la chercheuse titulaire de la recherche sur la présence de microplastiques dans le foie des anchois (Collard et al., 2017). La deuxième partie consistait à présenter brièvement aux élèves les trois types de supports puis de leur proposer d’en choisir un seul, en fonction de leurs goûts. Individuellement, ils devaient ensuite procéder à la lecture du document avec pour objectif d’essayer de comprendre et mémoriser ce dont il retournait dans le document en vue d’un post test de connaissance. Ce dernier clôturait cette seconde partie de la séquence. Après analyse des données des pré et post tests, les chercheurs ont pu mesurer quel mode de présentation des notions était le plus choisi et par quel type d’élèves, en fonction de leur profil. Ils ont pu montrer également l’influence de ce choix du support au niveau de l’apprentissage (Marin, Crinon, Legros & Avel, 2007). Ce sont ces résultats qui seront présentés de manière détaillée lors de l’intervention au colloque. Ajoutons que cette séquence issue de la recherche dont les résultats sont éclairants est dorénavant proposée, sous la forme d’un atelier à vivre, aux futurs enseignants en formation initiale. Ils sont soumis aux mêmes tests et procèdent aux mêmes choix que les élèves lors de la séquence d’enseignement. Les résultats de la recherche menée avec les élèves sont ensuite envisagés avec les futurs enseignants, afin qu’ils réalisent l’impact de la forme des supports pour l’étude sur l’apprentissage de leurs futurs élèves. En plus de cette sensibilisation, cet atelier permet également aux futurs enseignants de réaliser qu’il existe une recherche en didactique des sciences et que cette dernière peut influencer leurs modes d’enseigner pour favoriser l’apprentissage chez leurs élèves.

Cet article interroge la fonction de la généalogie et de l’héraldique des Guise au sein des courts imprimés polémiques que publièrent les catholiques ligués contre Henri III de 1585 à 1591. Afin de montrer comment ces disciplines prestigieuses ont été instrumentalisées, l’enquête explore les pratiques par lesquelles les libellistes en ont fait des arguments au service d’un discours politiques, interrogeant par exemple la récurrence de certains motifs ou la cohérence entre les deux disciplines étudiées. Elle montre ainsi que les polémistes ont utilisé plusieurs éléments du capital identitaire construit par les Guise depuis plus d’un siècle : la guerre des plumes sans précédent qui caractérise la fin des guerres de Religion française est le théâtre de tournants inédits pris par des argumentaires anciens, et ni la généalogie ni l’héraldique n’échappent pas à ce processus discursif.

En étudiant, dans une perspective pragmatique, la correspondance échangée entre le nonce Niccolò Guidi di Bagno et la secrétairerie d’État romaine, de 1647 à 1650, cet article s’est donné pour objectif de voir comment la Fronde dite Parlementaire agit sur la mission de paix que la diplomatie pontificale tente de mener à bien en servant de médiatrice entre les couronnes de France et d’Espagne, en guerre depuis 1635. En retour, il a visé aussi à voir comment cette mission de paix agit sur les regards que le nonce porte sur la Fronde. Il apparait rapidement que la figure de Mazarin est la clé de voûte de l’herméneutique proposée par Guidi di Bagno. Ambigu, complexe, le regard que le diplomate pontifical jette sur le cardinal-ministre est le fruit de la multitude des intérêts croisés de la papauté d’Innocent x et de ce dernier. Suspendre la France au seul destin de Mazarin est une technique narrative qui permet alors au nonce de construire la double image d’une royauté française en perdition et d’une papauté droite et juste qui fait face à la tempête de la Fronde au nom du bien commun et de Dieu.

We revisit the limit on very light axion-like particles (ALPs) from the absence of gamma rays coincidental with the neutrino burst from SN1987A. We use updated supernova simulations, modern models for the magnetic field inside the Galaxy, and a Primakoff cross section which takes into account proton-degeneracy and mass-reduction effects. We finally give an updated exclusion plot for the electromagnetic coupling of sub-eV ALPs, comparing our new bound with other limits as well as with future ALP searches. [less ▲]

Bernardo Dovizi, one of the most famous secretaries of the early Italian Reinassance, is best known for his literary works and for being the patron of Raffaello rather than for his endeavors in diplomacy. By deciding to follow the interests of Giovanni de’ Medici, Dovizi made some poor political decisions in his career but, in spite of this, he cunningly managed to get his patron become the Pope. The "Calandra" is a work that depicts well the author’s ideas, in between parody and classicism. From his works, Epistolario and Ricordi, it appears that the main strength of Dovizi is his irony, through which he manages to become almost an accomplice with his patron. Alongside with the iconological choice of the frescoes of his Stufetta and Loggia in the Vatican, he assumes the posture of the secretary-jester, as it was portrayed by Baldassarre Castiglione in "The Book of the Courtier": the satyr that washes into the room, used as bathroom, corresponds to the most famous pose of the patron who insists on these burlesque and mocking characteristics, although relating to Ovid and Plato. Bibbiena seems to be aware of how much the man that exceeds in praise himself appears unbearable, therefore, in his relations with members of the ruling class, he often assumes a playful attitude. In the Rome of Leo X, because of the Socratic 'serio ludere', such attitude was accepted and admired. The best instruments of Bibbiena are the pleasantness and a careful selection of humanistic ideals. Such ideals were those that suited better the environment in which he, the courtier, had to operate, and were used in his works. [less ▲]

The rapid uptake of renewable energy resources and displacement of synchronous generators may pose threats to system frequency stability and resilience. Starting from the August 2018 separation event in Australia, this work models and discusses how utility-scale PV plants could contribute to frequency stability and resilience of islanded areas following separation events. In this regard, a converter-based dynamic equivalent of aggregated PV power plants is proposed which takes into account possible practical issues such as measurement and coordination delays. The unknown parameters of the proposed model are identified through a novel closed-loop identification process based on least-square minimization. Also, a simplified model is constructed to reproduce the system frequency during the event under study, thereby capturing continuous impact of PV response on the frequency. The proposed aggregated model can considerably reduce the complexity of frequency stability analysis as well as its processing time while capturing with good fidelity the frequency response from PV farms.

The Sūtras display that the first mantra of the Yajurveda, iṣé tvorjé tvā, must be recited at the beginning of the darśapūrṇamāsa, when the priest selects and cuts off a branch intended for separating the calves from their mothers. The examination of the most archaic commentaries in prose, inserted in the collections of the Black Yajurveda shows nonetheless that this is a secondary development. Originally, the mantra was not regarding the branch, but rather the attribution to the sacrificer who benefits from the ritual exchange between men and the gods that intervene at daybreak. [less ▲]

En Belgique francophone, le décret « Missions » de 1997 a fixé le document « Socles de compétences » (Gouvernement de la Communauté française, 1999) comme étant le référentiel pré-sentant les compétences de base à exercer. En ce qui concerne l’éveil scientifique, ce référentiel adopte une position résolument en faveur de l’apprentissage d’une démarche scientifique. Plu-sieurs auteurs ont décrit cette démarche et ses différentes composantes qu’ils nomment tantôt « scientifique » tantôt « d’investigation » (Saltiel, 2005 ; Morge & Boilevin, 2007 ; Calmettes, 2009 ; Coquidé, Fortin & Rumelhard, 2009 ; Cariou, 2010, 2011 ; Daro, Graftiau & Stouve-nackers, 2015). Force est de constater que la mise en place, dans les classes, d’un enseignement axé sur une démarche scientifique ne se fait pas sans mal. Plusieurs auteurs en ont fait le constat (Demeuse & Monseur, 2000 ; Belleflamme, Graillon & Romainville, 2008 ; Conseil wallon de la Politique Scientifique, 2013). Partant de ces constats inquiétants, nous avons progressivement mis en place un dispositif de collaboration depuis l’année académique 2010-2011, sur le modèle de la communauté d’apprentissage de développement professionnel, vouée à l’apprentissage de l’enseignant (Wil-son & Berne, 1999, cités par Dionne & Couture, 2013 ; Samson, Lepage & Robert, 2013). Ce dispositif a pris place dans la formation initiale des futurs enseignants du niveau préscolaire (pour des élèves âgés de 2,5 à 6 ans) et dans celle des futurs enseignants en sciences biolo-giques du niveau secondaire supérieur (pour des élèves âgés de 15 à 18 ans). Ces formations émanent d’institutions différentes : les enseignants du préscolaire sont formés en trois années en Haute École pédagogique et ceux du secondaire supérieur, en un an à l’Université. La communauté d’apprentissage décrite prend place lors de la troisième et dernière année de formation des futurs enseignants de préscolaire. [less ▲]

Since Leopold von Ranke, historiography generally considers the official protest of the Holy See against the Peace of Westphalia (1648) as a sign of the weakening of papal influence in Europe. However, in recent years, several scholars have demonstrated the quality of the practices of Nuncio Fabio Chigi during his peace mediation in Münster. Based on these recent insights, this paper aims to revisit Chigi's protest policy, analysing it as a contextualised legal-diplomatic practice developed to address the difficulties of the Westphalian negotiations. First of all, it will recall the Papacy's conception of peace at the beginning of the congress and the peacemaking role that Rome assigned itself. Then, it will study Fabio Chigi's shift towards protest. Thus, it will be shown that the papal protest is not an unprecedented moment of political invention, but rather that it is part of the same project as peace mediation. Indeed, both positions are part of the doctrine of the padre comune. This paper highlights the adaptability of pontifical representation in the mid-seventeenth century in order to challenge modern diplomacy, in an interstate and interfaith context that puts the ideal of Christianity in tension.

La critique génétique est, comme le dit bien Jean-Louis Jeannelle, une « théorie en quête d’elle-même » , tiraillée entre la tradition philologique et les avancées structuralistes.

Comment les auteurs vont-ils, dans leur ouvrage, justifier leur parution au sein d’une collection dont les présupposés théoriques semblent, a priori, contraires à ceux présidant à leur travail ? Quelles en sont alors les implications méthodologiques, pour chacune des deux disciplines ? [less ▲]

Only one male portrait by Leonardo survives. Kept at the Pinacoteca Ambrosiana in Milan, it depicts a young man who, in one of his hands, holds a folded sheet on which one can make out letters and musical notes. Due to the poor conservation of this part of the picture, the music is now illegible, but it is definitely mensural notation and thus in all likelihood polyphonic music. During this intervention, I would like to return on the general attitude of the model, that of a young man captivated by the music he had just composed or sung. The next paradox will also be pointed: why face the sheet of music towards the outer portion of the tableau when the young man seems so focused on his internal thoughts? [less ▲]

Le projet EpistolART explore le matériau épistolaire dans le but de mieux préciser le statut socio-professionnel des artistes de la Renaissance italienne. Dans ce cadre, le "Carteggio inedito d’artisti dei secoli XIV, XV, XVI" de Johann Wilhelm Gaye (1839-1840) constitue l’un de nos corpus privilégiés. Méritoire le travail de Gaye n’en demeure pas moins dépassé : les transcriptions, souvent partielles et contestables, requièrent une actualisation, suivant les critères de la philologie, de la codicologie et de la paléographie moderne. Cette contribution s'organise autour de trois lettres évoquant Léonard de Vinci, lettres publiées dans les volumes de Gaye et dont les membres du projet EpistolART proposent une nouvelle édition. Elles constituent des documents extrêmement précieux pour écrire l’histoire des relations entre le maître florentin et la France. Si les historiens qui se sont penchés sur la vie et l’œuvre de Léonard de Vinci connaissent ces correspondances, rares sont ceux qui ont recouru aux documents épistolaires originaux. Or, ce n’est qu’au départ d’un texte sûr, appréhendé tant dans sa matérialité que dans ses contenus, que peuvent se déployer des analyses scientifiquement fondées. [less ▲]

Si les contours de la collection de livres de Louise de Savoie sont désormais connus, il reste encore beaucoup à découvrir en ce qui concerne sa collection particulière d’objets et d’œuvres d’art, comme ses rapports avec l’architecture et, plus largement, le rôle qu’elle a joué dans la politique culturelle et artistique de son fils, François Ier. Les personnalités attachées à sa maison demeurent aussi à distinguer. Les « rôles des officiers » et les comptes fournissent quelques noms, comme Robinet Testart, Bartolomeo Ghetti ou Matteo del Nassaro. D’autres sources nous permettent d’associer encore Antoine Juste, Léonard de Vinci, Andrea del Sarto, Girolamo della Robbia, Pierre Paule ou Pierre Mangot à la mère de François Ier. Au-delà de l’évocation des productions réalisées à l’attention de la comtesse puis duchesse d’Angoulême, nous tentons de définir la position que ces artistes occupèrent auprès de la princesse. Nous insistons aussi sur le fait que mère et fils emploient les mêmes personnalités : Madame recommanderait-elle les artistes à engager, participant de ce fait à la construction des collections royales sous François Ier ?

L’étude de la réception des écrits de Léonard de Vinci peut trouver un utile contrepoint dans l’évocation de propos tenus sur l’artiste et sur son œuvre peint dans les textes de théorie de l’art publiés en France au XVIIe siècle. Pour décrire le physique et le caractère du maître, les Français abondent d’adjectifs convenus, la plupart inspirés de Giorgio Vasari. Ils insistent aussi sur sa « grande variété de connoissance », son ingéniosité et son inconstance. En outre, ils ne remettent jamais en question l’importance décisive de Léonard dans l’évolution de la peinture, telle que Vasari l’avait exaltée en plaçant le maître en tête des peintres modernes. Cette affirmation n’en demeure pas moins paradoxale : alors que nombre d’œuvres peintes de Léonard sont conservées sur le sol français depuis l’époque de François Ier, certains auteurs avouent méconnaître son art. De plus, ses inventions peintes ne sont pas regardées comme des modèles à étudier ou à copier tandis qu’aucune de ses peintures n’est présentée lors des premières conférences de l’Académie royale de peinture et de sculpture. Cet exposé – qui s’attardera sur les termes et les notions employés dans les textes publiés en France pour décrire Léonard et ses tableaux – contribuera à mieux définir la renommée du peintre en France à l’époque moderne.

L'étude se consacre aux répercussions de la jurisprudence dite "Antigone" sur les décisions des administrations sociales au sens large, tant celle qui inflige l'amende administrative en cas d'infraction en droit social que les institutions de sécurité sociale. En abandonnant le principe de la légalité des preuves, la Cour de cassation a renforcé les moyens d’établir la vérité et de lutter efficacement contre les infractions, la fraude fiscale, la fraude sociale, la fraude économique, etc. En contrepartie, elle a diminué la protection des droits fondamentaux. Même les principes généraux de bonne administration ne semblent pas empêcher que l’autorité administrative prenne en compte une preuve illicite pour adopter une décision. Les administrations disposent donc de plus de latitude qu’auparavant pour sanctionner la fraude et veiller à ce que l’État reçoive son dû ou ne dépense pas indument. De cet outil, les administrations ne doivent pas abuser car la jurisprudence Antigone n’est pas sans limite. La preuve entachée de l’un des vices énoncés par la Cour de cassation prive la décision administrative de soutènement et expose celle-ci à une annulation ou une réformation par le pouvoir judiciaire.

À première vue, Montaigne ne semble pas avoir de point commun avec la pensée japonaise. Or, en y regardant de plus près, plusieurs similarités et affinités deviennent perceptibles. Ainsi, certains thèmes chers à Montaigne peuvent être comparés aux notions récurrentes des penseurs et écrivains japonais, qu’il s’agisse de leur rapport avec la nature, des relations entre individu et communauté ou du rôle des traditions et croyances dans la société. L’exposé rapprochera certaines facettes des « Essais » de Montaigne à la pensée japonaise. L’analyse de notions comme souplesse, mouvement, modération ou oisiveté, permettra de découvrir dans la sagesse de Montaigne une contribution originale et trans-culturelle. Dans ce contexte comparatif, une attention particulière sera accordée aux écrits du moine Kenkō et aux notions du bouddhisme-zen. En comparant certaines conceptions des « Essais » avec la pensée de Kenkō, comme la spontanéité, l’ignorance, l’inconstance ou le changement, l’exposé permettra de considérer Montaigne comme un précurseur de la pensée comparée.

This paper focuses on digital platforms supporting citizen participation in the era of Smart Cities. Our study presents and analyses two examples of online participation platforms, implemented by two Walloon cities: Mons and Liège (Belgium). These two cases highlight the differences and the similarities between both cities’ interpretation of digital participation, as well as the difficulties they faced, especially considering the data processing by city officials. In light of the challenges observed through those two cases, we suggest that digital platforms might potentially be misused, and somehow bias the whole digital participatory process. We therefore issue recommendations about how to design, launch and manage such platforms and, moreover, suggest that platforms should be supplemented by other digital or traditional participatory processes in order to reach higher levels of participation.

The cement pavements of the Domus dei Bucrani, a remarkable Late Republic villa unearthed from the deepest strata of the Schola del Traiano in Ostia Antica, have already been discussed in several publications. To this day, the context of the find, its chronological sequence and its description, all in relation with other elements of the Second Style decorative system, are well known amongst the specialised scientific community. Nevertheless, a technological analysis of these floors, in the specific context of the Latium production has yet to be completed. The documentation campaigns led at the moment by the Université de Liège on the site and in the deposits of Ostia Antica aim to fill this critical gap with a close study that will be supported by an archaeometrical analysis. The preliminary results of these ventures are presented here. [less ▲]

Notre intention est de montrer d’une part comment Louise de Savoie manifeste, par l’intermédiaire de ces signes emblématiques, son identité et son pouvoir, d’autre part comment elle construit, par leur biais, un patrimoine, mental, susceptible de renforcer son clan et ses héritiers.

This paper shows that the authors who first used diagrams to represent syntactic structures chose graphical conventions that constrained the way they could represent their analyses. Some graphical conventions may look similar despite following different rationales. Conversely, they may also look different and yet be grounded in the same logic. This second possibility becomes obvious when comparing the diagramming systems proposed by Clark (who uses aggregated bubbles) and Reed & Kellogg (who use strokes). Nevertheless, bi-dimensional objects such as bubbles offer more varied layout possibilities for drawing diagrams than mono-dimensional objects such as strokes do. Consequently, authors have to add the representation for abstract concepts such as inclusion by means that are compatible with the basic objects they use. [less ▲]

The paper will propose a reassessment of the evidence used to support such a hypothesis and, taking into account the achievements of the members of Deir el-Medina community of the 18th dynasty when they worked for themselves, it will suggest another model to answer the question raised by J.

Le 10 octobre 1517, le cardinal Louis d’Aragon, en voyage à travers la France, visite la ville d’Amboise. La même journée, au château de Cloux, il rencontre Léonard de Vinci : l’artiste lui présente trois tableaux, décrits comme « tucti perfectissimi », mais aussi des dessins et des notes qu’il avait l’intention d’organiser en vue de les publier notamment sous la forme d’un traité d’anatomie. Le lendemain, dans la bibliothèque du château de Blois, le cardinal et sa suite voient un tableau supplémentaire de l’Italien. Au cours de cet exposé, je voudrais revenir sur le témoignage qu’Antonio de Beatis, secrétaire du cardinal d’Aragon, laissa de cette visite en Touraine. Si certains propos sont confus et ont visiblement été précisés dans un second temps, ce qui ne facilite pas l’interprétation, cette relation se révèle en effet essentielle pour restituer les dernières années de la vie de Léonard à la cour de François Ier, notamment l’histoire de ses tableaux en France.

Since the middle of the 20th century, principles and ethical codes have multiplied in the field of conservation-restoration applied to works of art and architecture. Starting from the observation that this proliferation has not always stimulated the critical spirit of professionals, the CoToCoCo project aims to encourage reflection "out of the box". Case studies are confronted with concepts borrowed from disciplines outside the field of conservation-restoration, such as sociology, anthropology, philosophy, semiology and mathematics, among others. In this article, we examine two case studies of "lost art" through the prism of the concept of antifragility, developed by the mathematician Nassim Nicholas Taleb (1960-): The frescoes of St Francis Basilica in Assisi and the fragments of Victor Horta’s Hôtel Aubecq in Brussels.

Dynamic testing techniques provide the ground for quick and cheap identification strategies, based on the knowledge of: (a) a set of iden- tified natural frequencies, and (b) a structural model that relates natural frequencies to the axial-force value. Within this framework, reliability of the identified axial force values depends, among other factors, on the predictive capabilities of the underlying structural model. Errors may arise, in particular, from the modeling of boundary conditions. The present paper analytically investigates the effect of boundary conditions on the modal prop- erties of axially loaded Euler-Bernoulli beam elements. Starting from theoretical results obtained on this archetypal structural model, a numerical procedure for the identification of the axial force in beam elements with unknown bending stiffness and boundary condi- tions is then presented. Parametric analyses are carried out to quantitatively assess the accuracy of the proposed identification algorithm in the case of frequencies contaminated by measurement errors. [less ▲]

This paper recounts twenty years of experience in a multidisciplinary agency in which digital technology, and particularly BIM, has made it possible to decompartmentalize architectural design and deploy new collaborative models in architecture. Firstly, we look back at the initial promises of digital in architectural practice and the obstacles and shortcuts taken over the past decades. Secondly, we recount the emergence of the new multidisciplinary collaborative model developed within the agency. Based on this experience of multidisciplinary collaboration 4.0, we relate two perspectives under development based on digital technology, including the BIM collaborative process: systemic sustainability in architectural design on the one hand and the extension of the project management mission to facility management on the other hand. Through this article, we address the impact of digital technology on the metamorphosis of architectural practice through collaborative multi-disciplinarity. [less ▲]

The Multiple Timescale Spectral Analysis is a framework relying on the existence of well-separated timescales in the dynamic response of structures to generalize for higher-order statistics the famous background/resonant decomposition, widely applied by the wind engineer- ing community to compute the variance of the response of SDOF structures or of each modal response of MDOF structures. This fast spectral analysis method mainly concerns the statistics of the response of onshore structures subjected to a buffeting wind loading whose characteristic frequency is typically lower than the natural frequencies of the structures concerned. By con- trast, when dealing with wave-loaded floating offshore structures, the roles of the slow and fast timescales are likely to be interchanged and the method is extended further in this paper to com- pute rapidly the variances and the skewnesses of modal responses of such structures responding in the inertial regime as well, since these statistics are necessary to consider the influence of the non-Gaussianity of the loading.

In most of the concept designs for nuclear waste disposals, bentonite-based materials are used to seal underground galleries and shafts. In order to assess the safety of such engineered barriers and to provide a good prediction for the material behaviour, a number of experimental campaigns and constitutive models have been developed mainly focusing on bentonite compacted blocks. On the other hand, in recent years, the use of high density bentonite pellets combined with powdered bentonite has also been considered as an interesting alternative. The bentonite pellets mixtures present a prominent initial heterogeneity level as a result of the inter-pellets porosity, which evolves strongly during hydration. This paper aims to present the numerical modelling strategy adopted for a swelling pressure test on pellets mixture carried by CEA (France). Taking advantage of the finite element code LAGAMINE, the Barcelona Basic model is considered for the bentonite mechanical behaviour and the double porosity model proposed by [1] is used for the water retention behaviour and permeability evolution. Given the already-known complexity of the multiphysical and multiscale coupled processes taking place during bentonite-hydration, the obtained numerical results are in good agreement with experimental measurements. Especially, the non-monotonic evolution of the swelling pressure during the hydration phase is well captured by this model, which is always a challenge for this type of problem. [less ▲]

INTRODUCTION: Ultra-marathons are defined as races covering a distance of more than 42.2 kilometers. During the last 10 years, participation in these type of challenge has become increasingly attractive to millions of non-professional endurance athletes worldwide. The aim of this study is to investigate the impact of intense exercise, represented by different endurance races, thank to oxidative stress and cardiac markers. METHODS: Four populations were compared, a control group of 16 participants “ sedentary” (SED)( 37,0 ± 4,4years old), a group of 24 semi-marathon runners(SEMI) ( 41,0 years ± 8,76 years old), a group of 28 marathon runners (MARA) ( 44,1 ± 8,4 years old) and a group of 33 ultra-trail runners (UT) ( 45,8 ± 8,7 years old). Three blood tests were drawned, one just before, one just after, and the last three hours after the end of the race. Different oxidative stress and cardiac biomarkers were measured on different devices according to the manufacturer specifications. RESULTS: Myeloperoxydase increased significantly (p<0.0001) during exercise except for SED, but the release is significantly different according to the level of training of the runners. Glutathion oxidized/reduced ratio seems to remain stable during the race except for SED and UT. A significantly decrease in lipidic peroxidation was observed during exercice(p<0.01). We noticed a significantly increase of creatine kinase, isoform MB, myoglobin and C-reactiv protein during the race (p<0.0001) and was significantly different according to the race (p<0.0001). We observed a very significant increase of troponin T and natriuretic peptide (p<0.0001) but with a different kinetic than the one obtained for a myocardial infarction. CONCLUSION: Endurance races provocate the income of oxidative stress objectified by different biomarkers increase, but a cell necrosis is not specially observed. In fact, the increase of the cardiac markers during endurance races may be explained by a transient modification of myocyte permeability and by micro-muscle damages causing an inflammatory process explaining our observations of markers of inflammation.

Recent advances in architectural geometry and the rising ubiquity of design computation and Visual Programming (VP) amongst architecture practices has led to the design and construction of more complex, larger scale architectural projects. Consequently, the Architecture, Engineering and Construction (AEC) industry has witnessed the emergence of custom technological solutions tailored within some of the most progressive architecture practices to better understand and visualize complex digital design workflows. Although very relevant, such existing solutions have always been developed in isolation to solve particular design problems related to the conception and construction of a specific building project. Based on this observation, the open-source data platform for AEC called Speckle has been developed in order to bring more transparency in the design process, enabling multiple stakeholders working from different software environments to seamlessly communicate through its web interface. The present paper both introduces the platform and describes an interactive data flow diagram – named SpeckleViz – built upon it to support in a user friendly manner transparent collaborative design, project management and version control for AEC. This will be illustrated through two selected case studies. [less ▲]

Semantic background subtraction (SBS) has been shown to improve the performance of most background subtraction algorithms by combining them with semantic information, derived from a semantic segmentation network. However, SBS requires high-quality semantic segmentation masks for all frames, which are slow to compute. In addition, most state-of-the-art background subtraction algorithms are not real-time, which makes them unsuitable for real-world applications. In this paper, we present a novel background subtraction algorithm called Real-Time Semantic Background Subtraction (denoted RT-SBS) which extends SBS for real-time constrained applications while keeping similar performances. RT-SBS effectively combines a real-time background subtraction algorithm with high-quality semantic information which can be provided at a slower pace, independently for each pixel. We show that RT-SBS coupled with ViBe sets a new state of the art for real-time background subtraction algorithms and even competes with the non real-time state-of-the-art ones. Note that we provide python CPU and GPU implementations of RT-SBS at https://github.com/cioppaanthony/rt-sbs [less ▲]

There exist many background subtraction algorithms to detect motion in videos. To help comparing them, datasets with ground-truth data such as CDNET or LASIESTA have been proposed. These datasets organize videos in categories that represent typical challenges for background subtraction. The evaluation procedure promoted by their authors consists in measuring performance indicators for each video separately and to average them hierarchically, within a category first, then between categories, a procedure which we name “summarization”. While the summarization by averaging performance indicators is a valuable effort to standardize the evaluation procedure, it has no theoretical justification and it breaks the intrinsic relationships between summarized indicators. This leads to interpretation inconsistencies. In this paper, we present a theoretical approach to summarize the performances for multiple videos that preserves the relationships between performance indicators. In addition, we give formulas and an algorithm to calculate summarized performances. Finally, we showcase our observations on CDNET 2014. [less ▲]

INTRODUCTION: Fatigue is a multifactorial, complex phenomenon that limits athletes’ performances. Transcranial direct current stimulation (tDCS) could be an interesting option to reduce supraspinal fatigue. However, to date, very little research has been done on the effects of tDCS on confirmed athletes. Our objective is to compare the effects of tDCS on endurance performance in confirmed athletes METHODS: Our study is a randomized, double-blind, cross-over study. 30 men aged between 18 and 30 years old were split into two groups (tDCS week 1 and sham week 2, or sham week 1 and tDCS week 2). All were right handed and footed, and had no positive answer on the TSST screening scale. They came to the University Hospital’s Isokinetic Lab twice to undergo a fatiguing protocol (30 maximal concentric repetitions over a 100° flexion amplitude at 180°/s). 20 min of either anodal or sham tDCS, with the anode over C3 and the cathode over FP2. We measured peak tork and work for both quadriceps and hamstrings in the dominant limb. RESULTS: There were no significant effects of tDCS compared to sham on quadriceps peak tork for the first 10, second 10 and final 10 repetitions (respectively 1,5%, 2% and 4,7% difference) or maximal work (respectively 1,5%, 2,5% and 5%), nor for first 10 repetitions of hamstring peak tork (2,5%) and work (3,6%). However, close to significant effects were seen on the second 10 contractions for peak tork values (p= 0,087, 4,75%) and significant effects were sean for the peak tork in the final 10 repetitions (7%), the maximal work in the second 10 repetitions (6,4%) and the final 10 repetitions (9%). CONCLUSION: Significant effects on hamstring fatigue were found after tDCS when compared to a sham treatment. These effects could potentially be explained by reducing supraspinal fatigue, or by decreasing perceived discomfort felt during the protocol. [less ▲]

In this study, a digital impedance is used to realize both a linear and a nonlinear piezoelectric tuned vibration absorber in order to mitigate the vibrations of a nonlinear structure. The digital processing unit enables the synthesis of impedances with arbitrary functional forms, thereby easing the implementation of nonlinear absorbers. The superior performance of the nonlinear absorber over its linear counterpart is demonstrated experimentally. Various nonlinear functional forms are also tested in the absorber and illustrate the relevance of the principle of similarity (i.e. the same nonlinear functional form as that in the host structure should be used in the absorber).

Tendinopathy is a major problem in medicine and sports traumatology. It is due, inter alia, to mechanical overload. It remains a challenge for the medical world to the extent that its frequent resistance to conventional treatments never promises the patient a favourable response following therapeutic management. The development of platelet-rich plasma (PRP) is a new hope when therapeutic treatments such as NSAIDs, corticosteroid injections, eccentric rehabilitation, shock waves, etc. have shown their limits. Furthermore, it is no longer included on the list of doping substances. Indeed, platelets contain various growth factors which participate to the tendon healing process. PRP is obtained by centrifugation of autologous blood to obtain a platelet concentration greater than that of the blood, which varies according to the production method. PRP also contains a variable amount of lymphocytes and erythrocytes that can have a detrimental effect on wound healing. Currently, there is no formal consensus regarding the production method or the biological composition of PRP. Many laboratory studies (in vitro and/or on animal) emphasize the acceleration of the healing tendon process after injection of PRP, each growth factor exerting a specific action during healing. PRP would cause the proliferation, migration and differentiation of cells derived from circulation, improving the initial phase of the tendon healing. This anabolic process initiates the type I collagen synthesis. Although currently the effectiveness of PRP on tendon healing in vitro or in animals seems to be confirmed, clinical studies are currently still controversial. In addition, there is still only a limited number of randomized and controlled studies reviewing PRP for treating tendinopathy. However, it seems that PRP can be efficient to treat lateral epicondylitis, patellar tendinopathies and plantar fasciitis, even if the level of proofs remains low. Up to now there is not enough proofs concerning the use of PRP to treat rotator cuff or Achilles tendinopathies. More randomized, controlled and blinded studies remain needed. In conclusion, experimentally, PRP, through the local release of various growth factors stimulates tendon healing. This therapy could optimize the healing of pathological human tendons. PRP should be analysed to see whether it improves tendon healing in both humans and animals through other randomized controlled trials. [less ▲]

In this paper, we show that the hardware ecosystem of network operators can greatly vary from one to another, with all potential security implications it brings. Indeed, depending on the autonomous system (AS), not all brands play the same role in terms of network connectivity. An attacker could find an interest in targeting a specific hardware vendor in a particular AS, if known defects are present in this hardware, and if the AS relies heavily on it for forwarding its traffic.

Over the past few decades, architectural practice and, consequently, the design studio have been increasingly challenged. Indeed, the development of digital tools and parametric design, in particular, has given rise to a new type of architectural knowledge.

We then report a learning situation through studio design education. This paper finally presents the steps developed to measure this knowledge and hypothesizes on the future work needed in order to have relevant quantitative results. The purpose of this paper is to observe the evolution of students' understanding when shifting from a traditional teacher-student relationship to an engaging learning environment, considering the specificities of parametric, and not to suggest a strict method to follow when learning parametric. This could guide teachers to adapt to their own situations. [less ▲]

The dynamic behavior of bladed disks in resonance crossing has been intensively investigated in the community of turbomachinery, addressing the attention to (1) the transienttype response that appear when the resonance is crossed with a finite sweep rate and (2) the localization of the vibration in the disk due to the blade mistuning. In real conditions, the two mentioned effects coexist and can interact in a complex manner. This paper investigates the problem by means of analytic solutions obtained through asymptotic expansions, as well as numerical simulations. The mechanical system is assumed as simple as possible: a 2-dof linear system defined through the three parameters: damping ratio , frequency mistuning , rotor acceleration  . The analytic solutions are calculated through the multiple-scale method. [less ▲]

A closed form state-space model of the nonlinear aeroelastic response of thin cantilevered flat plates is derived using a combination of Inextensible thin plate theory and a linearized continuous time vortex lattice aerodynamic model. The modal-based model is solved for the amplitude and period of the limit cycles of the flat plates using numerical integration. The resulting predictions are compared to theoretical predictions obtained using Von K´arm´an thin plate theory for an identical flat plate. It is shown that the aeroelastic model predicts the linear flutter conditions and nonlinear response of the plates with reasonable accuracy and the Limit Cycle Oscillation (LCO) amplitude, calculated from the inextensible plate theory, has an initial curvature very similar to the one obtained during of experimental test on similar plates, contrary to the amplitude predictions of the Von-Karman model. This striking feature is very encouraging for future experimental and numerical work. [less ▲]

Flutter and divergence behaviour for discrete bodies in the farfield has long been considered, such as in wing-empennage interaction but not for long, slender bodies in a non-rotating frame (like that encountered in wind turbines). This work focuses on filling that knowledge gap. As such, flutter behaviour has been determined for flat plates of varying planforms in various combinations and configured either in parallel or in series. A dimensionless separation parameter based upon the chord has been selected. A closed form state-space model for the nonlinear aeroelastic response of thin cantilevered flat plates has been derived using a combination of the MSC.NASTRAN commercial structural solver and a linearised continuous time vortex lattice aerodynamic model with an image inspired cascade. The modal-based model is solved for the amplitude and period of the limit cycles of the flat plates using numerical continuation. These results are compared to experimental data obtained from identical flat plates in a wind tunnel. [less ▲]

Electrical distribution systems need to integrate more and more renewable energy generation in their network. Since networks cannot be quickly upgraded at a low cost, new generators are connected to the network under non-firm access contracts. These contracts allow distribution system operators to specify dynamic access limits according to a given regulatory policy, e.g. “last-in, first-out” or a similar policy. Due to operational delays, access limits must be communicated before realtime, e.g. ten minutes ahead. This paper presents an operational method to compute these dynamic access limits using correlated probabilistic forecasts of power consumption and production processes. The method is illustrated on a test-case based on real data where no additional production would be allowed under firm access. Results show that the method allows to safely integrate additional production capacity while limiting congestion events, provided that efficient probabilistic forecasts able to anticipate sudden and important changes are available.

The Frequency Containment Reserve (FCR) is one of the balancing actions to keep the frequency within acceptable limits. The objective of the FCR (also known as primary control) is to stabilize the system frequency within a short time interval after a disturbance. Related to that, maximum steady-state frequency deviation and maximum Instantaneous Frequency Deviation (IFD) are defined. With higher integration of renewable energy sources, power systems will reduce its impact on pollution, but face much more often with low inertia scenarios. With low inertia values, the system decreases its inherent property to react to large power disturbances. In these cases, IFD is profoundly affected, and there is a need for fast and cost-effective solutions. High Voltage Direct Current (HVDC) links with appropriate control strategies may be a potential solution for the challenge mentioned above. According to current system requirements, HVDC links must be capable of providing frequency support. Several studies analyzed the impact of FCR action via HVDC systems with various control methods. However, the question is which of these methods has the best properties in terms of reliability, robustness, and cost-effectiveness. This work investigates and applies two control methods for HVDC frequency support in the Nordic test system, where these actions are referred to as Emergency Power Control (EPC). The first EPC method is currently used in the Nordic Power System (NPS), and it is based on ramp power injections and frequency triggering activations. The second one is a frequency droop based EPC, and this work proposes it as a new method for future EPC operation. This work assesses the comparison between the two EPC methods for two different disturbances and with the same EPC power capacities. The main objective of the EPC is to meet the frequency requirements and avoid any negative interactions. The Nordic test system has been designed and tuned by authors to capture the frequency dynamical response of the NPS. Furthermore, an equivalent single machine model with low inertia is used to study the performance of the frequency droop based EPC. [less ▲]
