ELLPAG - Economics of Long-Life Pavement

One of the most important research efforts developed to date is the European Project ELLPAG (European Long-Life Pavement Group). It was founded, in 2002, as a FEHRL group to gather the European knowledge. The group has been active since then, and it has be ...

The link between the infinite mapping class group of the disk and the braid group on infinitely many strands

Jan Brunner

φ For all finite n ∈ N, there is a well-known isomorphism between the standard braid group Bn and the mapping class group π0Hn. This isomorphism has been exhaustively studied in literature, and generalized in many ways. For some basic topological reason, t ...

Reduced Lagrangian and Hamiltonian formulations of Euler-Yang-Mills fluids

Tudor Ratiu, François Gay-Balmaz

The Lagrangian and Hamiltonian structures for an ideal gauge-charged fluid are determined. Using a Kaluza-Klein point of view, the equations of motion are obtained by Lagrangian and Poisson reductions associated to the automorphism group of a principal bun ...

Some applications of symmetries in differential geometry and dynamical systems

Oana Mihaela Dragulete

This thesis deals with applications of Lie symmetries in differential geometry and dynamical systems. The first chapter of the thesis studies the singular reduction of symmetries of cosphere bundles, the conservation properties of contact systems and their ...

Advances in the Design and Implementation of Group Communication Middleware

André Schiper, Sergio Mena, Olivier Rütti, Rachele Fuzzati, Daniel Bünzli

Group communication is a programming abstraction that allows a distributed group of processes to provide a reliable service in spite of the possibility of failures within the group. The goal of the project was to improve the state of the art of group commu ...

Drug loading of porous coating

Heinrich Hofmann, Laurent-Dominique Piveteau

Porous coating for the controlled release of drugs, said coating comprising a porous structure with pores adapted to act as reservoirs or as passages for a drug, in such a way that said drug can move from the external environment to/from or through said po ...

Predicting sizing dependent bending rigidity of glass fibre bundles in sheet moulding compounds

Véronique Michaud, Emmanuelle Comte

The effect of sizing on bending rigidity in fibre bundles was investigated. Particular attention was paid to the effect of film formers and anti-static agents on the behaviour of glass fibre bundles under forced packing conditions. The bending rigidity of ...

Trace coordinates of Teichmüller space of Riemann surfaces of signature $(0,4)$

Klaus-Dieter Semmler, Thomas Gauglhofer

Summary: We explicitly give

calT

, the Teichmüller space of four-holed spheres (which we call

X

pieces) in trace coordinates, as well as its modular group and a fundamental domain for the action of this group on

calT

which is its moduli space. As a co ...

Detecting Group Interest-level in Meetings

Daniel Gatica-Perez, Samy Bengio, Dong Zhang

Finding relevant segments in meeting recordings is important for summarization, browsing, and retrieval purposes. In this paper, we define relevance as the interest-level that meeting participants manifest as a group during the course of their interaction ...

Confocal microscopy using variable-focal-length microlenses and an optical fiber bundle

Liza Carol Andrea Dunbar, Toralf Scharf, Lin Yang

The use of variable-focal-length (VFL) microlenses can provide a way to axially scan the foci across a sample by electronic control. We demonstrate an approach to coupling VFL microlenses individually to a fiber bundle as a way to create a high-throughput ...
