Gaia Data Release 1 Summary of the astrometric, photometric, and survey properties
Stephan Morgenthaler, Mikaël Martino, Shuangqing Liao
Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7. Aims. A summary of Gaia DR1 is presented along with illu ...
EDP Sciences2016Rayleigh-Taylor instability under an inclined plane
François Gallaire, Gioele Mariano Nicolò Balestra, Pierre-Thomas Paul Brun, Pierre Rieu
We revisit the canonical Rayleigh-Taylor instability and investigate the case of a thin film of fluid upon the underside of an inclined plane. The presence of a natural flow along the plane competes with the conventional droplet forming instability. In par ...
2015In-Plane Mode Dynamics of Capillary Self-Alignment
Massimo Mastrangeli, Pierre Lambert
We present an experimental study of the complete in-plane dynamics of capillary self-alignment. The two translational (shift) and single rotational (twist) in-plane modes of square millimetric transparent dies bridged to shape-matching receptor sites throu ...
American Chemical Society2014Broadband excitation in solid-state NMR using interleaved DANTE pulse trains with N pulses per rotor period
Geoffrey Bodenhausen, Diego Carnevale, Simone Ulzega
We analyze the direct excitation of wide one-dimensional spectra of nuclei with spin I = 1/2 or 1 in rotating solids submitted to pulse trains in the manner of Delays Alternating with Nutations for Tailored Excitation (DANTE), either with one short rotor-s ...
Elsevier2013Dam breaks of viscoplastic material on an inclined plane.
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 on an inclined plane. ...
Engineers Australia, July2011Experimental 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 ...
Elsevier2009Simulating Viscoplastic Avalanches.
Christophe Ancey, Martin Rentschler
We present a comparison between experiment and numerical results for the dam-break problem involving viscoplastic fluids. The laboratory experiment consists in releasing a fine volume of a viscoplastic fluid down inclined plane and tracking the evolution o ...
2008Alignment and signed-intensity anomalies in WMAP data
Pierre Vandergheynst, Yves Wiaux
Significant alignment and signed-intensity anomalies of local features of the cosmic microwave background (CMB) are detected on the three-year WMAP data, through a decomposition of the signal with steerable wavelets on the sphere. In addition to identifyin ...
2007Measurements of time-dependent free-surface viscoplastic flows down steep slopes
The objective of this thesis was to increase our understanding of gravity-driven geophysical flows by developing a new platform to simulate avalanches of fluid in the laboratory. To simulate flow avalanches in the laboratory, we created a unique experiment ...
EPFL2007Global universe anisotropy probed by the alignment of structures in the cosmic microwave background
Pierre Vandergheynst, Yves Wiaux
We question the global universe isotropy by probing the alignment of local structures in the cosmic microwave background (CMB) radiation. The original method proposed relies on a steerable wavelet decomposition of the CMB signal on the sphere. The analysis ...
