PEGASE (Planification Et Gestion de l’ASsainissement des Eaux) is an integrated model “basin/river” which makes possible to calculate in a deterministic way the water quality of rivers according to pollutant contributions and releases, for various stationary hydrological situations (see http://hdl.handle.net/2268/35224 for more information). In the scope of the Water Framework Directive international coordination, the transnational surface water quality model PEGASE is already in use (since 2005) for the Southern part of the Meuse basin (France, Luxemburg, Wallonia and a small part of Flanders). It was thus of great interest to extend this surface water quality application to the Northern part of the Meuse basin, i.e. the German, Flemish and Dutch downstream parts of the basin, in order to cover the entire district. This document describes the tasks which were devoted to the Research & Development Unit of the Aquapôle of the University of Liège (Aquapôle-ULg) in order to realize the extension of the Pegase database to the German Maas basin and to run the model on the German watershed.

We consider extensions and restrictions of Wythoff's game having exactly the same set of P positions as the original game. No strict subset of rules give the same set of P positions. On the other hand, we characterize all moves that can be adjoined while preserving the original set of P positions. Testing if a move belongs to such an extended set of rules is shown to be doable in polynomial time. Many arguments rely on the infinite Fibonacci word, automatic sequences and the corresponding number system. With these tools, we provide new two-dimensional morphisms generating an infinite picture encoding respectively P positions of Wythoff's game and moves that can be adjoined. [less ▲]

Wythoff's game is a century old classical two players combinatorial game. When studying this game, Beatty sequences associated with the Golden Ratio, syntactical properties of the representations of integers in the Fibonacci or Zeckendorf numeration system and the morphic Fibonacci word appear naturally in characterizations of its P-positions. Recall that whatever is the move played from a P-position, the other player has a winning strategy. Contrarily to the usual approach where one defines a new game by a set of rules and then tries to characterize the corresponding set of P-positions, our motivations are to proceed the other way around: keep the original set of P-positons while changing the rules. We consider extensions and restrictions of Wythoff's game having exactly the same set of P-positions as the original game. Our results are the following one: no strict subset of rules gives the same set of P-positions. On the other hand, we characterize all moves that can be adjoined while preserving the original set of P-positions. Testing if a move belongs to such an extended set of rules is shown to be done in polynomial time. In this talk, we won't consider many game theoretical aspects (but we will recall some basic facts on combinatorial games). We focus mainly on the role played by numeration systems, regular languages and bidimensional words generated by substitutions/morphisms. Indeed, games like this one provide nice interaction between combinatorics on words and combinatorial game theory. For instance, the set of P-positions of Wythoff's game are "coded" by the infinite Fibonacci word. Therefore, many arguments rely on this word, on automatic sequences and on the corresponding numeration systems. With these tools, we provide new bidimensional (shape-symmetric in the sense of Arnaud Maes) morphisms generating an infinite picture encoding respectively P-positions of Wythoff's game and moves that can be adjoined preserving the same set of P-positions.

Mitral valve repair has demonstrated its superiority over valve replacement. Mitral valve repair constitutes the optimal therapeutic option in case of degenerative dystrophic, rheumatic, congenital or ischemic mitral valve disease. These surgical techniques can also be successfully and advantageously applied in case of bacterial endocarditis or tumoral valvular disease. We report a case of staphylococcal endocarditis and another case of posterior leaflet fibroelastoma to show the place of conservative mitral surgery in these unusual indications. [less ▲]

Extensions modernes du concept de fonction Comme la plupart des concepts mathématiques, celui de fonction s’est transformé progressivement pour devenir ce qui nous en est enseigné aujourd’hui. Il évolue encore de nos jours : il est toujours plus général, mais également plus abstrait et sophistiqué. Nous donnons ici un petit aperçu intuitif de quelques-unes de ses généralisations modernes.

Cataloguant au départ les notices des papyrus littéraires grecs et latins, à l'exclusion des papyrus d'Herculanum et des textes magiques, bibliques, juifs et chrétiens, le fichier Mertens-Pack3, qui est intégralement accessible en ligne depuis décembre 2005, s'étend progressivement à d'autres catégories de papyrus étudiés dans le cadre de recherches du CEDOPAL sur les mise en texte et contexte des papyrus grecs et latins. Aux notices des papyrus iatromagiques, disponibles en ligne depuis novembre 2004, succéderont progressivement celles des papyrus latins d'Herculanum, des lettres et textes scolaires chrétiens, des rapports médicaux et des lettres privées à caractère médical, etc., tandis que seront fournies toutes les bibliographies liminaires par auteur et par sous-genre, et que l'architecture de la base de données sera entièrement remaniée en vue d'optimiser les conditions tant d'encodage que de consultation.

The concept of system signature was introduced by Samaniego for systems whose components have i.i.d. lifetimes. We consider its extension to the continuous dependent case and give an explicit expression for this extension as a difference of weighted means of the structure function values. We then derive a formula for the computation of the coefficients of these weighted means in the special case of independent continuous lifetimes. Finally, we interpret this extended concept of signature through a natural least squares approximation problem. [less ▲]
