Membership, binarity, and rotation of red dwarfs in the nearby open cluster Coma Berenices (Melotte 111)

Context. Although several attempts have been made to identify solar-type members on the main sequence of the nearby open cluster Coma Berenices (Mel 111), the population of the lower main sequence is still poorly known. ...

An exploratory search for z greater than or similar to 6 quasars in the ukidss early data release

Frédéric Courbin, Georges Meylan, Alexander Patrick Eigenbrod

We conducted an exploratory search for quasars at z similar to 6-8, using the Early Data Release (EDR) from the United Kingdom Infrared Deep Sky Survey (UKIDSS) cross-matched to panoramic optical imagery. High-redshift quasar candidates are chosen using mu ...

Membership and binarity of solar-type dwarfs in the nearby open cluster Alpha Persei (Mel 20)

Jean-Claude Mermilliod

Context. The Alpha Persei open cluster (Melotte 20) is one of the nearby clusters (d < 500 pc) for which a long-term systematic radial-velocity monitoring of the solar-type stars has not been published so far. ...

Specification, estimation and validation of a pedestrian walking behavior model

Michel Bierlaire, Gianluca Antonini, Javier Cruz Mota, Thomas Robin

We propose and validate a model for pedestrian walking behavior, based on discrete choice modeling. Two main types of behavior are identified: unconstrained and constrained. By unconstrained, we refer to behavior patterns which are independent from other i ...

Detection of cavitation in hydraulic turbines

François Avellan, Mohamed Farhat, Eduard Egusquiza

An experimental investigation has been carried out in order to evaluate the detection of cavitation in actual hydraulic turbines. The methodology is based on the analysis of structural vibrations, acoustic emissions and hydrodynamic pressures measured in t ...

Highly dispersed gold on activated carbon fibers for low temperature CO oxidation

Philippe Buffat, Lioubov Kiwi, Elena Suvorova Buffat

Gold nanoparticles of 2–5 nm supported on woven fabrics of activated carbon fibers (ACF) were effective during CO oxidation at room temperature. To obtain a high metal dispersion, Au was deposited on ACF from aqueous solution of ethylenediamine complex [Au ...
