Biometric Template Privacy Using Visual Cryptography

Sana Ibjaoun, Denis Berdjag, Vincent Poirriez, A. Ouamane

One of the critical steps in designing a secure biometric system is protecting the templates of the users. If a biometric template is compromised, it leads to serious security and privacy threats because unlike passwords, it is not possible for a legitimate user to revoke his biometric identifiers…

The integrated multi-quay Berth Allocation and Crane Assignment Problem: Formulation and case study

Issam Krimi, Laurent Deshayes, Rachid Benmansour, Abdessamad Ait El Cadi, David Duvivier, Nizar Elhachemi, Amine Ait Ouarrasse

In the literature, some works deal with the integrated Berth Allocation and Crane Assignment Problem (BACAP) in container and bulk port context. Most of them consider that equipment are always available and high tide periods restriction is not imposed. In this work, we were interested by the BACAP…

Gait‐based human age classification using a silhouette model

Nabila Mansouri, Mohammed Aouled Issa, Yousra Ben Jemaa

Age estimation at a distance has potential applications including visual surveillance and monitoring in public places. Far from the camera, image resolution is significantly degraded. In fact, age estimation using classical methods such as face is not reliable. Given that gait is very sensitive to…

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.…

Radiative heating of a glass plate: the semi-discrete problem (second revision)

Luc Paquet

In a preceding paper (MSIA, 2012), we have studied the radiative heating of a glass plate. We have proved existence and uniqueness of the solution. Here, we want to study the semi-discrete problem and to prove a priori error estimates. Previously, in that purpose, we have to study the regularity of…

Flat Almost Complex Surfaces in the Homogeneous Nearly Kähler S3×S3

Bart Dioos, Haizhong Li, Hui Ma, Luc Vrancken

By employing a nice adapted frame we prove a Bonnet-type existence and uniqueness theorem for almost complex surfaces in the homogeneous nearly Kähler manifold S3×S3. The proof uses a local correspondence between almost complex surfaces in S3×S3 and surfaces in R3 that satisfy the Wente H-surface…

Ultrathin electrochemically driven conducting polymer actuators: fabrication and electrochemomechanical characterization

Ngoc Tan Nguyen, Kätlin Rohtlaid, Cedric Plesse, Giao T.M. Nguyen, Caroline Soyer, Sébastien Grondel, Eric Cattan, John D.W. Madden, Frederic Vidal

Electronic conducting polymer based-actuators have attracted lots of interest as alternative materials to traditional piezoelectric and electrostatic actuators. Their specific characteristics such as their low operating voltages and large strains should allow them to adapt better to soft…

Vers Une Ecosse indépendante?

Edwige Camp-Pietrain

En 2014, le SNP a bénéficié de facteurs exceptionnels (tant politiques et juridiques qu'économiques et sociaux) afin de convoquer le référendum d'autodétermination promis depuis fort longtemps. Le Brexit aurait pu créer de nouvelles circonstances favorables, les Écossais pouvant décider…, The SNP benefited in 2014 from exceptional factors, be they political, legal, economic or social, in order to hold the referendum on independence that it had long promised. Brexit might have provided another set of advantageous circumstances as the Scots could decide to leave the United Kingdom in…
