Coherent actions by homeomorphisms on the real line or an interval

We study actions of groups by orientation preserving homeomorphisms on R (or an interval) that are minimal, have solvable germs at +/-infinity and contain a pair of elements of a certain dynamical type. We call such actions coherent. We establish that such ...

Monotonic Prefix Consistency in Distributed Systems

Rachid Guerraoui, Jad Hamza, Dragos-Adrian Seredinschi

We study the issue of data consistency in distributed systems. Specifically, we consider a distributed system that replicates its data at multiple sites, which is prone to partitions, and which is assumed to be available (in the sense that queries are alwa ...

An Improved LP-based Approximation for Steiner Tree

Thomas Rothvoss, Laura Sanità

The Steiner tree problem is one of the most fundamental

\mathbf{NP}

-hard problems: given a weighted undirected graph and a subset of terminal nodes, find a minimum-cost tree spanning the terminals. In a sequence of papers, the approximation ratio for thi ...

Étude des fondements physiques possibles des concepts numériques utilisés dans les méthodes d'acoustique géométrique

Thomas Guignard

The subject of the work presented here is the study of the acoustical ray method, which aims at describing a pressure field by an analogy with light rays. The concept of a wave is therefore replaced by the concept of "acoustical rays", whose paths through ...

Signal modeling with Non Uniform Topology lattice filters

Sacha Krstulovic

This article presents a new class of constrained and specialized Auto-Regressive (AR) processes. They are derived from lattice filters where some reflection coefficients are forced to zero at a priori locations. Optimizing the filter topology allows to bui ...

Dispositif électronique à affichage électro-optique commandé par des circuits logiques programmables

Daniel Mange, Christof Teuscher

NOVELTY - The electronic display (2) includes a number of cells (12) whose upper faces form a display surface, each cell has an electro-optic display unit (6) with inputs (14) for data to be displayed. A programmable logic circuit (20) is associated with f ...
