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, ...

Competition and Cooperation

Numerous applications of economics are based on models that assume individual economic actors take prices as given. Indeed, this assumption underlies many empirical studies. The question of whether such an assumption can be justified as arising in the context of individual and group optimizing behavior has been the subject of extensive investigation.One answer to the question originates with the work of Edgeworth (1881), which argues that groups individuals cannot improve upon their part of a price-taking economic equilibrium by cooperation, that is, the set of outcomes that are stable against collective activities of groups – the core-- is equivalent to ...

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 ...
