A Polyvinylidene fluoride (PVDF) based bimorph actuator for high speed laser beam manipulation

Hannes Bleuler, Reymond Clavel, Ricardo Pérez Suárez

High-speed laser manipulation is a key technology in applications such as fast optical switches for coupling light into optical fibres, 2D beam steering for optical scanners, laser printers or 2D sensors. A novel design of a Polyvinylidene Fluoride (PVDF) ...

On the influence of gravel bed dynamics on velocity power spectra

Fernando Porté Agel

A series of flume experiments were conducted to study the effect of bed form dynamics on the flow over a gravel bed comprising a wide distribution of grain sizes. Instantaneous high-frequency streamwise flow velocities were sampled using an acoustic Dopple ...

Polymer Viscoelasticity in Shear

Fabienne Meier

Polymer materials may exhibit significant viscoelastic behaviour under various type of deformations. A model that can describe various viscous behaviours in simple tension was proposed in a previous work of the laboratory of biomechanical orthopedics. This ...

METHOD AND DEVICE FOR DETERMINING THE APICAL POSITION IN A DENTAL ROOT CANAL

Pierre-André Farine, Cyril Botteron

The invention relates to an apex-locating method and device for determining the depth position of the apex in a dental root canal. It uses a device that makes it possible to form a circuit comprising a first electrode-probe inserted in the root canal of a ...

Experimental investigation of the spreading of viscoplastic fluids on inclined planes

Christophe Ancey, Steve Cochard

We report experimental results related to the dam-break problem for viscoplastic fluids. Using image processing techniques, we were able to accurately reconstruct the free-surface evolution of fixed volumes of fluid suddenly released a plane. We used Carbo ...

Shunt loudspeakers for modal control in rooms

Hervé Lissek, Romain Boulandet, Pierre-Jean René

Engineers dealing with noise reduction in habitations close to transportation traffic or indus-trial facilities encounter several problems to decrease noise level in rooms at low frequencies. Passive materials and current building construction knowledge en ...

Implantable ultra-low power DSP-based system for a miniature chemico-rheological biosensor

Peter Ryser, Eric Meurville, Léandre Bolomey

An active implantable chemico-rheological sensor including control electronics, a Digital Signal Processor (DSP) and an RF transceiver has been demonstrated. The ultra-low power system architecture achieves an energy per viscosity measurement of only 16.6m ...

Plasticity and geophysical flows: A review

Christophe Ancey

The objective of this review is to examine how the concept of plasticity is used in geophysical fluid dynamics. Rapid mass movements such as snow avalanches or debris flows involve slurries of solid particles (ice, boulder, clay, etc.) within an interstiti ...
