Seismic behaviour of different types of masonry spandrels

Most residential buildings that were constructed during the last century in Switzerland are 2-6 storey unreinforced masonry (URM) structures. At the beginning of the century, houses were constructed with timber floors and small bricks. This type of constru ...

Multilingual acoustic modeling for speech recognition based on subspace Gaussian Mixture Models

Pinar Akyazi, Samuel Thomas

Although research has previously been done on multilingual speech recognition, it has been found to be very difficult to improve over separately trained systems. The usual approach has been to use some kind of “universal phone set” that covers multiple lan ...

Structural Changes in Industrial R&D in Europe and the US

Dominique Foray, Stéphane Lhuillery

We analyse the structural changes that have characterised the organisation of industrial R&D over the last 25 years. Taking Mowery's work (Industrial and Corporate Change, 2009, 18(1), 1-50) on the US as a starting point, we reconsider the different aspect ...

Electron trapping in substoichiometric germanium oxide

Alfredo Pasquarello, Peter Broqvist, Jan Felix Binder

Model structures of substoichiometric germanium oxide generated by ab initio molecular dynamics reveal a rich variety of bonding configurations, including threefold coordinated Ge and O atoms which correspond to valence alternation pairs. A sizable fractio ...

Roombots-Towards Decentralized Reconfiguration with Self-Reconfiguring Modular Robotic Metamodules

Auke Ijspeert, Mikaël Mayer, Alexander Spröwitz, Rico Möckel, Stéphane Bonardi, Pierre-André Mudry, Philippe Laprade

This paper presents our work towards a decentralized reconfiguration strategy for self-reconfiguring modular robots, assembling furniture-like structures from Roombots metamodules. We explore how reconfiguration by locomotion from a configuration A to a co ...

Coalgèbres d'Alexander-Whitney

Théophile Naïto

The goal of this work is to study Alexander-Whitney coalgebras (first defined in [HPST06]) from a topological point of view. An Alexander-Whitney coalgebra is a coassociative chain coalgebra over Z with an extra algebraic structure : the comultiplication m ...

The combined use of radio-frequency electromagnetics and radiomagnetotellurics methods in non-ideal field conditions for delineating hydrogeological boundaries and for environmental problems

Aurèle Parriaux, Pascal Turberg

Radio frequency geophysical methods are known for being very versatile tools in ground- and groundwater investigation at shallow depths. They are fast and easy to use and allow a high density of information over large surfaces, which makes them very suitab ...

Structuration of thin bridge and cantilever structures in thick-film technology using mineral sacrificial materials

Peter Ryser, Thomas Maeder, Caroline Jacq, Yannick Sébastien Fournier, Wassim Hraiz

Thick-film and LTCC (Low Temperature Cofired Ceramic) technologies find increasing use in meso-scale sensors, actuators and related devices that feature excellent dimensional, thermal and chemical stability at moderate cost. While several materials and pro ...
