Réhabilitation de la capacité d’évacuation des crues – intégration de "PK-Weirs" sur des barrages existants

Anton Schleiss, Martin Peter Bieri, Marcelo Leite Ribeiro

La réhabilitation des barrages existants impose généralement une augmentation de leur capacité d’évacuation en crue. Dans de nombreuses situations, le PK-Weir (Piano Key Weir) offre à cet égard une solution compacte et efficace. La conception et la réalisa ...

The Case for Structured Random Codes: Beyond Linear Models

Michael Christoph Gastpar

Recent work has shown that for some multi-user networks, carefully controlling the algebraic structure of the coding scheme may be just as useful as selecting the correct input distribution. In particular, for linear channel models, including finite field ...

The algebra of connectors - Structuring interaction in BIP

Joseph Sifakis, Simon Bliudze

We provide an algebraic formalization of connectors in the BIP component framework. A connector relates a set of typed ports. Types are used to describe different modes of synchronization: rendezvous and broadcast, in particular. Connectors on a set of por ...

Foncteurs de Mackey projectifs

This work deals with the study of projective Mackey functors. Mackey functors are algebraic structures with operations which behave like induction, restriction and conjugation in group representation theory. These objects have properties which generalize m ...

Transport phenomena in nanofluidics

Philippe Renaud, Reto Bruno Schoch

Transport of fluid in and around nanometer-sized objects with at least one characteristic dimension below 100 nm renders possible phenomena that are not accessible at bigger length scales. This research field is termed nanofluidics and received its name on ...
