The Frobenius Problem and Its Generalizations

The classical but oddly little-known Frobenius problem from number theory is the following: given a set of positive integers with greatest common divisor equal to 1, find the largest integer not representable as a non-negative integer linear combination of the set elements. This largest integer is called the Frobenius number. For example, the Frobenius number of 6, 9, and 20 is 43. In this talk I will survey some of the known results on this problem and its applications to computer science, and a new generalization of this ...

Quantum Turing Test

The research community has made spectacular progress in building the magical quantum machines, developing new applications, designing security platforms up until the current state where the verification question is hunting us down. The required experiments are not beyond our reach and have been implemented, even in a basic optical setting, but these are quantum experiments simulating quantum theory. So even if we assume the correctness of quantum theory, we are soon reaching to the domain that we are not able to verify the correctness of experimental ...

Swarms: First Class Citizens in the Future Internet (série : Colloquium Jacques Morgenstern)

The current Internet consists of tens of thousand different interconnected autonomous networks. It was designed to support large populations of point-to-point content transfers. This introduces considerable headaches due imbalances in traffic flows, which has the effect of complicating network management, reducing the robustness of the Internet, and reducing user performance. In this talk, I review the sources of traffic in the Internet over the last 20 years. We will observe that this an increasing fraction of traffic was generated by peer-to-peer (P2P) "swarm" technology from 2000 to 2007. I examine how and why P2P swarm technology simplifies network management, ...

Mathematical models for the cardiovascular system

Mathematical models for the cardiovascular system: analysis, numerical simulation, applications The role of mathematics in understanding and simulating fluid dynamics and biochemical processes in the physiological and pathological functioning of the human cardiovascular system is becoming more and more crucial. These phenomena are indeed correlated with the origin of some major cardiovascular pathologies, and influence the efficacy of the treatments to heal the arteries from their diseases. Mathematical models allow the description of the complex fluid-structure interaction which govern the artery wall deformation under the pressure pulse. Moreover, appropriate reduction strategies can be devised to allow for an ...

Action recognition from video: some recent results

While recognition in still images has received a lot of attention over the past years, recognition in videos is just emerging. In this talk I will present some recent results. Bags of features have demonstrated good performance for action recognition in videos. We briefly review the underlying principles and introduce trajectory-based video features, which have shown to outperform the state of the art. These features are obtained by dense point sampling in each frame and tracking them based on displacement information from a dense optical flow field. Trajectory descriptors are obtained from motion boundary histograms, which are robust to ...

Demain, la médecine

Le monde de la médecine est aujourd’hui dans la tourmente du financement, de l’organisation et de l’éthique. Dans un tel contexte, comment construire la médecine de demain ? Pour Vincent Dousset, l’amélioration de la médecine passe par une plus forte collaboration entre les sciences fondamentales et les sciences humaines et sociales (démographie, psychologie, sociologie…). Les médecins doivent s’aider des autres disciplines du champ de la réflexion pour redéfinir les maladies et les combattre. Cet effort vers un travail collaboratif plus efficace permettra de ramener les questions de santé dans le débat public et de faire de la médecine une priorité ...
