We are often interested in explaining data through a set of hidden factors or features. When the number of hidden features is unknown, the Indian Buffet Process (IBP) is a nonparametric latent feature model that does not bound the number of active features in dataset. However, the IBP assumes that all latent features are uncorrelated, making it inadequate for many realworld problems. We introdu...

The paper reviews recent achievements in the application of smart-materials actuation to counteract aeroelastic and vibration effects in helicopters and fixed wing aircraft. A brief review of the induced-strain actuation principles and capabilities is done first. Attention is then focused on the smart rotor blade applications. Induced twist, active blade tip, and active blade flap are presented...

We present an implicit large-eddy simulation of transonic buffet over the OAT15A supercritical airfoil at Mach number 0.73, angle attack 3.5 deg, and Reynolds . The is performed using a matrix-free discontinuous Galerkin (DG) method diagonally Runge–Kutta scheme on graphics processor units. propose Jacobian-free Newton–Krylov to solve nonlinear systems arising from discretization Navier–Stokes ...

Mobile eye tracking (MET) enables the recording of gaze data in less-controlled research environments, but best practices for its use studies about visual attention to foods are yet undetermined. This study supports building a coherent framework this methodological approach by discussing current eye-tracking trends field, applying MET an experiment with real foods, and proposing approaches futu...

Abstract An experimental investigation was performed in order to better understand the transonic shock buffet phenomenon and determine dominant flow interactions at specific conditions. A rigid wing shape of an OAT15A airfoil placed Trisonic Wind Tunnel Munich, where both Mach number angle attack were varied between $$0.65&lt; M_\infty &lt; 0.77$$ <mml:math xmlns:mml="http://www.w3.org/1998/Mat...

Deux « grands » candidats devenus petits : Robert Hue et Marie-George Buffet communistes aux élections présidentielles de 2002 2007. Ces constituent pour le Parti communiste français un véritable recul, voire choc. Le PCF devient une force électorale négligeable n’enraie pas son déclin, bien au contraire. En sept ans, 1995 à 2002, il perd 1 671 980 voix en douze ans (1995-2007), 925 192 voix, s...
