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 ...

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 ...

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 ...

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 ...

Fabrication of gold nano- and microstructures in ionic liquids - A remarkable anion effect

Paul Joseph Dyson, Zhaofu Fei

Au nano- and microstructures such as polyhedral crystals, large single-cryst. nanoplates, hollow trapeziform crystals, holey polyhedra, and dendrites were produced via microwave heating of HAuCl4·4H2O in a variety of ionic liqs. (ILs) in the absence of cap ...

Tunable plasmonic nanostructures

Olivier Martin, Holger Fischer

We discuss different composite plasmonic nanostructures, which optical properties can be tuned by displacing some of their parts at the nanoscale. The actuation of these structures with MEMs will define new optical functionalities. ...
