Flat almost complex surfaces in the nearly Kähler S3 × S3

Luc Vrancken

In this talk we show how to study almost complex submanifolds of S3 × S3. Compact 6-dimensional non-K¨ahler nearly K¨ahler manifolds do not admit 4-dimensional almost complex submanifolds, so the almost complex submanifolds are surfaces. Previously, a classification of the totally geodesic almost...

Lagrangian relaxation-based lower bound for the two-machine flow shop with synchronized periodic maintenance

Issam Krimi, Rachid Benmansour, Nizar Elhachemi, David Duvivier

In this work, we present a Lagrangian relaxation approach to generate a new lower bound for the two-machine flow shop scheduling problem under synchronized and periodic maintenance activities. The word synchronized is used to specify that the maintenance starts at the same time on both machines....

Eigen frequencies and directivity patterns of a spherical acoustic transducer

Daher Diab, Fabrice Lefebvre, Georges Nassar, Nikolay Smagin, Adnan Naja, Fawaz El Omar

In this work, a spherical acoustic sensor has been developed, and is composed of two Plexiglas half-spheres and a PZ26 piezoelectric ring that can be either used as an exciter or as a sensor. The resonance of the spherical shell is studied analytically, numerically by finite elements modeling in...

Designing a camera placement assistance system for human motion capture based on a guided genetic algorithm

Azeddine Aissaoui, Abdelkrim Ouafi, Philippe Pudlo, Christophe Gillet, Zine-Eddine Baarir, Abdelmalik Taleb-Ahmed

In multi-camera motion capture systems, determining the optimal camera configuration (camera positions and orientations) is still an unresolved problem. At present, configurations are primarily guided by a human operator’s intuition, which requires expertise and experience, especially with complex...

Computation of dispersion curves of guided waves using discontinuous Galerkin finite element method: Application to functionally graded materials

Salah-Eddine Hebaz, Farouk Benmeddour, Emmanuel Moulin, Jamal Assaad, Marc Duquennoy, Mohammadi Ouaftouh

The study of dispersive behavior of guided waves is of great interest in non-destructive testing and development of inspection systems. In this work, a semi-analytical numerical formulation for the computation of dispersion curves and mode shapes in plate-like structures is presented. The...

On Convective Heat Transfer and Flow Dynamics Through a Straight T-Bifurcating Channel

Abdelhak Lakehal, Nora Nait Bouda, Julien Pellé, Souad Harmand

Both experimental and numerical studies of a turbulent flow in a bifurcating channel are performed to characterize the dynamical behavior of the flow and its impact on the convective heat transfer on the sides of the branch. This configuration corresponds to the radial vents placed in the stator...

L'Ecosse sous Theresa May: résurgence des enjeux constitutionnels en réaction au Brexit

Edwige Camp-Pietrain

Le référendum sur le Brexit a provoqué la résurgence des enjeux constitutionnels en Écosse, en trois étapes distinctes jusqu’à la fin de l’année 2017. Nicola Sturgeon, forte du soutien de la majorité des électeurs et des élus écossais, a tout d’abord tenté de proposer l’adhésion à l’EEE afin de...
