SMD pressure and flow sensor for compressed air in LTCC technology with integrated electronics

Peter Ryser, Thomas Maeder, Yannick Sébastien Fournier, Nicolas Craquelin, Jean-Bastien Coma

In this work, we present an integrated flow / pressure / temperature multisensor in LTCC (low- temperature co-fired ceramic) technology designed for diagnostics monitoring of standard industrial compressed air circuits and devices, such as valves and actua ...

Design optimisation of the ITER divertor magnetic probes using FEM analyses

Alexander Karpushov

This paper is focused on the design, simulation and optimisation of the ITER divertor magnetic tangential coils. The most critical issue for the divertor coils is to minimise RITES [G. Vayakis, et al., Radiation-induced thermoelectric sensitivity (RITES) i ...

Influence of self heating and Li2SO4 addition on the microstructural development of calcium aluminate cement

Karen Scrivener, Emmanuel Gallucci, Christophe Gosselin

Hydrated Calcium Aluminate Cement (CAC) is known to have a complex microstructure involving different phase assemblages strongly dependant on the temperature. This work presents an experimental approach to study the microstructure of CAC pastes from the fi ...

Magnetic screening in proximity effect Josephson-junction arrays

The modulation with magnetic field of the sheet inductance measured on proximity effect Josephson-junction arrays (JJAs) is progressively vanishing on lowering the temperature, leading to a low-temperature field-independent response. This behaviour is cons ...

Homogeneous and inhomogeneous linewidth broadening of single polar GaN/AlN quantum dots

Nicolas Grandjean, Raphaël Butté, Dobri Simeonov

We report on the dependence on temperature of the homogeneous and inhomogeneous broadening of the fundamental transition of single polar GaN/AlN quantum dots (QDs). Stranski-Krastanov QDs have been grown by molecular beam epitaxy using NH3 as a nitrogen so ...

Temperature Monitoring During Tissue Freezing Using Ultrasound Speed Measurements

Martin Vetterli, Ali Hormati, Ivana Jovanovic

A major limitation of thermal therapies is the lack of detailed thermal information needed to monitor the therapy. Temperatures are routinely measured invasively with thermocouples, but only sparse measurements can be made. Ultrasound tomography is an attr ...

Surface Heterogeneity Effects on Regional-Scale Fluxes in Stable Boundary Layers: Surface Temperature Transitions

Fernando Porté Agel

Large-eddy simulation, with recently developed dynamic subgrid-scale models, is used to study the effect of heterogeneous surface temperature distributions on regional-scale turbulent fluxes in the stable boundary layer (SBL). Simulations are performed of ...

Etude des propriétés morphologiques et catalytiques d'agrégats d'or triés en taille et déposés sur le TiO2(110)

Raphaël Vallotton

This thesis aims to find, for the first time, a direct relation between the size and morphology of small metallic nanostructures (gold in this case) supported on a metal-oxide surface to their catalytic activity. In this perspective, three main topics have ...

Numerical simulation of solid state phase transformations in gamma-TiAl alloys

Amin Rostamian

Gamma titanium aluminide (γ-TiAl) based alloys are very interesting materials for structural applications at elevated temperatures owing to the combination of high specific strength, good oxidation, creep and fatigue resistance. However, their relatively p ...

Chemically peculiar stars and their temperature calibration

Pierre North

Aims. The determination of effective temperature for chemically peculiar (CP) stars by means of photometry is a sophisticated task due to their abnormal colours. Standard calibrations for normal stars lead to erroneous results and, in most cases correction ...
