Mechanical stabilisation and design optimisation of masks for stencil lithography: Numerical approach and experimental validation

Jürgen Brugger, Andreea Veronica Savu, Marc Antonius Friedrich van den Boogaart

This paper addresses mask deformation phenomenon that frequently occurs but is highly undesirable in stencil lithography. Previously, a technique for mechanical stabilisation of stencils was proposed [M.A.F. van den Boogaart, et al., Corrugated membranes f ...

Modélisation analytique multiphysique pour la conception optimale de moteurs synchrones à aimants permanents

Patrick Ragot

During the last years, permanent magnets synchronous motors have become a reference in the industrial world, both from the economical and the technical point of view, because of their very good performance in both regards. Thus, application of specific met ...

User-Involved Preference Elicitation for Product Search and Recommender Systems

Pearl Pu Faltings, Li Chen

We address user system interaction issues in product search and recommender systems: how to help users select the most preferential item from a large collection of alternatives. As such systems must crucially rely on an accurate and complete model of user ...

Large Deformation Balloon Micro-Actuator Based on Pyrotechnics on Chip

Nico de Rooij, Danick Briand, Herbert Shea, Samuel Rosset

This communication presents the modeling and the first demonstration of very large deformation balloon actuators based on pyrotechnics on chip. The gas and pressure generated by the combustion of a solid propellant stored in a micromachined cavity lead to ...

Experimental study on the fatigue behaviour of welded tubular K-joints for bridges

Alain Nussbaumer, Ann Schumacher

Fatigue tests were carried out on welded circular hollow section K-joints typical to bridges. The tests specimens were large-scale (approximately 9 m long and 2 m high) trusses loaded in the plane of the truss. Measured member stresses showed that a signif ...

An overview of the technique of asymmetrical multilevel inverters

Alfred Rufer

This paper deals with cascade multilevel inverters. It focuses on asymmetrical topologies where the cell input voltages are of different values. These hybrid topologies might be interesting for several applications. One of the main benefit is the high reso ...

Attractor learning with nonlinear, artificial, neural network

A nonlinear recurrent neural network is trained to synthesize chaotic signals. The identification process is reduced to a teaching phase and a linear regression. The influence of the shape of the nonlinearity in the neurons and the noise amplitude are stud ...

High extraction efficiency, laterally injected, light emitting diodes combining microcavities and photonic crystals

Romuald Houdré, Jean-François Carlin, Ursula Oesterle, Henri Benisty

The use of photonic crystals (PCs) for realistic light emitting diodes (LEDs) is discussed, given the constraints of planar semiconductor technology. A viable route for the fabrication of high-efficiency high-brightness electrically injected LEDs is presen ...

Primary-backup replication: From a time-free protocol to a time-based implementation

André Schiper

Fault-tolerant control systems can be built by replicating critical components. However, replication raises the issue of inconsistency. Multiple protocols for ensuring consistency have been described in the literature. PADRE (Protocol for Asymmetric Duplex ...
