Lattice-Boltzmann (LB) simulation methods constitute a family of computational fluid dynamics methods that can deal with complex multiphysics models and are easily parallelizable. They are based on modified lattice-gas automata. The algorithm of LB simulations is quite simple. Space is discretized into a lattice. Each node of this lattice has a state. This state indicates the proportion of particules moving along fixed directions (these proportions are generally called “fields”). At each time step, the state of all lattice nodes is updated. Each node first receives fields coming from its neighbors and then “collides” them by applying a collision operator which generates the new state. Grid computing can be defined as “coordinated resource sharing and problem solving in dynamic, multi-institutional collaborations”. In practice, a Grid user (which can be a software component) submits a job composed of tasks to the Grid. The tasks are automatically run on available computational resources across organizational boundaries (i.e. clusters of multiple departments). LaBoGrid is an application combining the concepts of LB modelling and Grid computing. It is able to run LB simulations on an arbitrary number of computational resources from a Grid. It deals with operating system and hardware performance heterogeneity. The former because LaBoGrid is written in Java. The latter thanks to load-balancing. This is essential because all LaBoGrid tasks are inter- connected and depend on information from one another. A slow LaBoGrid task will slow down the overall process. LaBoGrid is based on asynchronous agents exchanging messages. The two main agents are the Controller agent (CA) and the distributed agent (DA). In a deployed LaBoGrid system, the CA exists in only one instance. It keeps track of the DAs and their topology. A task agent running some arbitrary code can be attached to the CA (CAT) and the DAs (DAT). In LaBoGrid, LB-specialized task agents are used (this system could be adapted to other problems). A configuration file parsed by the LB CAT gives the parameters of an LB simulation. The LB CAT configures automatically the LB DATs which handle the simulation code. Currently, LB simulations are done on 3D fluids with 19 fields per state. However, the code can be adapted very easily to other fluid dimensions and different state definitions, storage and computation precisions and collision types. [less ▲]

The end of the medieval era and the beginning of modern times are marked by the increasing importance of urban centres. But this period of time is also crucial for the reconstruction of religious buildings in rural areas. As a few scholars like Luc-Francis Génicot have already pointed out, a large quantity of church works were going on during the 15th and 16th century in villages throughout Europe. Although architectural historians often ignore these « marginal » buildings, these are nonetheless products of human activity and must therefore find a place within the scientific study of architecture. This lecture will then present the way the researcher, using the most recent approaches in architectural history, can reintegrate these buildings into the discipline. To study these parish churches, the architectural historian is confronted with an important amount of items. He has to understand the reasons for such abundance of constructions as well as their distribution in time and space. While dealing with formal and stylistic questions, the researcher should avoid any normative attitude leading to consider these churches simply as places of stylistical conservatism. Finally, for these low documented buildings, the architectural historian should try to answer questions as to planning, financing and implementation of church works. As a consequence, he also has to identify the various interveners in the building process. [less ▲]

Intitulé "L’architecture textuelle de l’œuvre romanesque de Boris Vian : entre construction et destruction. Analyse des macro-, méso- et microstructures", le mémoire a déterminé un mode de composition, une double logique constructive et destructive – l’architecture textuelle – dans un ensemble romanesque choisi (six romans de Boris Vian). Il a également examiné l’interaction entre cette structure romanesque et des normes préexistantes (littéraires, langagières, sociales, etc.). À cette fin il a été nécessaire de délimiter trois niveaux textuels : (1) la macrostructure, (2) la mésostructure, (3) la microstructure. [less ▲]

L'histoire de l’architecture s’écrit aussi avec les reliques : qui dit reliques dit édifices pour les abriter, les mettre en valeur et les objets sacrés vont exercer une influence sur les formes du sanctuaire. Une spatialisation du sacré s’accomplit par la distribution des reliques dans l’église, reflet d’une hiérarchie des saints, conjointe à l'usage liturgique. Le nord, la Lotharingie, le pays mosan, en recèlent de beaux exemples. S’élabore parallèlement une forme de discours sur l’Église et sur la société chrétienne à l’âge roman. The history of architecture is also written with relics and constructions to house and develop them : sacred objects will influence the forms of the sanctuary. Spatialization of the sacred takes place by the distribution of relics in the church, reflecting a hierarchy of saints, conjoint to the liturgical use. The North, the Lotharingia, the Mosan region, show fine examples. These elaborated a parallel form of discourse on the Church and the Christian society at the Roman age. [less ▲]

Le présent rapport avait pour objectif d’éclairer les choix de la BICfB en matière d’archivage pérenne des périodiques électroniques, en examinant en particulier les conditions contractuelles des abonnements en cours et les solutions tierces d’archivage existantes (LOCKSS, CLOCKSS, Portico), en évaluant le coût des solutions envisagées, en articulant ces solutions avec l’archivage papier et en proposant des scénarios d’application. Il propose en conclusion une échelle de solutions garantissant l’accès pérenne aux périodiques électroniques, en distinguant une stratégie prioritaire, basée sur la participation à la LOCKSS Alliance, la présence de clauses garantissant l’accès aux titres sur la plateforme éditeur en cas de transfert, de cessation de publication ou de fin d’abonnement, et la prise en compte de l’archivage via CLOCKSS, et des pistes complémentaires, plus diverses et plus ou moins coûteuses, à sélectionner au cas par cas en fonction d’éléments externes et d’analyse coûts-bénéfices, pour garantir la préservation pérenne du portefeuille non couvert par le premier scénario.

This paper examines the archive as a space of re-creation for contemporary artists. More specifically, it deals with contemporary found footage films recycling aesthetically discredited material (industrial film, medical footage, porn, etc.). In particular, this paper focuses on Peter Tscherkassky’s latest work, "Coming Attractions" (2010). In this film, the Austrian filmmaker reworks and repurposes various advertising films and stresses the multiple connections he can identify between contemporary experimental film, the avant-garde (Fernand Léger, Henri Chomette, among others), the aesthetics of publicity and, allusively, the cinema of attractions (Lumière, Méliès, R. W. Paul). [less ▲]
