Liquid–liquid two-phaseflow patterns andmasstransfer characteristics inrectangular glassmicroreactors

Albert Renken, Lioubov Kiwi, Anne-Laure Dessimoz

The flow of two immiscible fluids was investigated in rectangular glass microchannels with equivalent diameters of 269 and 400

\mu m

. Deionised water, dyed toluene and hexane were selected as probe fluids. Flow patterns were obtained for Y- and T-junction ...

Analysis of large scale hydrodynamic phenomena in turbine draft tubes

Monica Iliescu

Hydraulic power is a renewable energy with a very advantageous price, and its flexibility of use coupled with its storage possibilities easily enables to meet the peak demand. Refurbishment of old hydraulic power plants is an important topical issue and th ...

Pitfalls in Estimating the Returns to Corporate R&D Using Accounting Data

Dominique Foray

Does R&D have an impact on firm growth, profits, and value? To most observers, the obvious answer is yes. However, the recent report by Booz-Allen-Hamilton (BAH 2006) seems to conclude that the share of spending devoted to research has no relationship to t ...

Integrated LTCC micro-fluidic modules - an SMT flow sensor

Peter Ryser, Thomas Maeder, Yannick Sébastien Fournier, Raphael Willigens

This paper presents a thermal flow sensor based on the calorimetric principle realized by using low temperature co-fired ceramic (LTCC) technology, where the tapes and flow channel have been structured by laser machining. A standard configuration of a calo ...

Cavitation Luminescence from Flow over a Hydrofoil in a Cavitation Tunnel

François Avellan, Mohamed Farhat

This paper describes a photon-counting study of the cavitation luminescence produced by ﬂow over a hydrofoil. This has previously been identiﬁed in water saturated with xenon. The four objectives of this study are: to determine whether luminescence can be ...

CMOS image sensors for subretinal implant system

Mihai Adrian Ionescu, Philippe Renaud, Marco Mazza

Visual capabilities recovery for some kind of illness is possible through subretinal implantable device stimulation. Two possible approaches for retinal pixel are proposed, fabricated in 0.35mum CMOS, tested and compared including electronic response on a ...

New support vector algorithms for multicategorical data applied to real-time object recognition

Silvio Borer

Humans have the ability to learn. Having seen an object we can recognise it later. We can do this because our nervous system uses an efficient and robust visual processing and capabilities to learn from sensory input. On the other hand, designing algorithm ...

Physical investigation of cavitation vortex collapse

Philippe Couty

Among the different negative cavitation effects that are associated with the cavitation presence (efficiency drop, noise and vibrations etc.), cavitation erosion is still one of the main limiting features in the modern trend towards designing hydraulic mac ...

Database Integration: the Key to Data Interoperability

Stefano Spaccapietra, Christine Parent

Most of new databases are no more built from scratch, but re-use existing data from several autonomous data stores. To facilitate application development, the data to be re-used should preferably be redefined as a virtual database, providing for the logica ...
