Application des réseaux de Bragg à la détermination des déformations distribuées dans les matériaux composites

The behaviour of brittle matrix fibre reinforced-composites is dependent of the properties of its constituents (fibre, matrix and fibre-matrix interface) and is affected by the mechanical and environmental loads. The fracture of a unidirectional composite ...

Sliding-induced adhesion of stiff polymer microfiber arrays. II. Microscale behaviour

Bryan Edward Schubert

The adhesive pads of geckos provide control of normal adhesive force by controlling the applied shear force. This frictional adhesion effect is one of the key principles used for rapid detachment in animals running up vertical surfaces. We developed polypr ...

Seepage and settlement monitoring for earth embankment dams using fully distributed sensing along optical fibers

Luc Thévenaz, Yao Zhou, Pingyu Zhu

A method for seepage and settlement monitoring in earth embankment dams using fully distributed sensing along optical fibres is proposed. A model is developed for simulating and monitoring seepage and settlement systems. This model relates the strains and ...

Advanced trends in nonlinear optics applied to distributed optical-fibre sensors

Dario Alasia

The distributed optical-fibre sensors based on the properties of Brillouin scattering is the central object of this thesis. In the past decade, optical fibres have gained a large interest as sensors: attractive solutions based on the non-linear stimulated ...

Capteur chimique à fibres optiques pour la mesure des ions chlore dans le béton à un stade précoce

Francine Laferrière

In the national and worldwide context, countless reinforced concrete structures are in an advanced state of deterioration. A principal cause of such degradation is chloride induced corrosion of reinforcement bars. This phenomenon is accentuated in countrie ...

UV metal semiconductor metal detectors - A robust choice for (Al, Ga)N based detectors

Nicolas Grandjean, Mauro Mosca

UV detection is interesting for combustion optimization, air contamination control, fire and solar blind rocket launching detection. Most of these applications require that UV detectors have a huge dynamic response between UV and the visible, and a very lo ...

Bandwidth-Constrained Mapping of Cores onto NoC Architectures

Giovanni De Micheli, Srinivasan Murali

We address the design of complex monolithic systems, where processing cores generate and consume a varying and large amount of data, thus bringing the communication links to the edge of congestion. Typical applications are in the area of multi-media proces ...

Reliability and lifetime of optical fibres and fibre bragg gratings for metrology and telecommunications

This thesis presents new developments on the different intrinsic failure mechanisms of silica optical fibres and fibre Bragg gratings with regard to applications in the fields of telecommunications and metrology. These failure mechanisms are mainly due to ...

Tensile tests on optical fibre cables using distributed Brillouin analysis

Luc Thévenaz, Philippe Robert, Alexandre Fellay

On-site distributed strain measurements using an original Brillouin analyser were performed on cables using standard tensile test bench and on critical installations in the Swiss telecom network. ...

Fault Localization at the WDM layer

Jean-Yves Le Boudec, Patrick Thiran, Carmen Mas

A single failure in a communication network may trigger many alarms. When the communication network uses optical fibres as transmission medium and increases its capacity by using Wavelength Division Multiplexing (WDM), the number of alarms and the difficul ...
