Performance and Coherence in Network Industries

Matthias Finger, Marc Laperrouza, Nicolas Crettenand, Christof Lorenz Duthaler

Network industries, such as electricity, railways and air transport, are very complex technical, economic, and political systems in which the interplay of technology and institutions has a significant impact on performance. While the performance of the net ...

Étude et optimisation d'un convertisseur DC/DC à canaux multiples entrelacés

Yannick Louvrier

In a context in which economy and ecology follow historically opposed trajectories, renewable energies appear as an interesting compromise. However, the energy production from these emerging technologies is well below that of their ancestors, and their cos ...

High-speed flow visualization in a pump-turbine under off-design operating conditions

François Avellan, Mohamed Farhat, Vlad Hasmatuchi, Steven Roth, Francisco Botero

The flow hydrodynamics in a low specific speed radial pump-turbine reduced scale model is experimentally investigated under off-design operating conditions in generating mode. Wall pressure measurements, in the stator, synchronized with high-speed flow vis ...

Swift Algorithms for Repeated Consensus

André Schiper, Martin Hutle, Fatemeh Borran, Nuno Filipe de Sousa Santos

We introduce the notion of a swift algorithm. Informally, an algorithm that solves the repeated consensus is swift if, in a partial synchronous run of this algorithm, eventually no timeout expires, i.e., the algorithm execution proceeds with the actual spe ...

CHARON: Routing in low-density opportunistic wireless sensor networks

Jorge Miguel Dias Almeida Rodrigues Soares

Combining wireless sensor networks (WSNs) with delay-tolerant networking (DTN) has the potential to extend their use in a multitude of previously impossible applications. However, and despite numerous proposed solutions, there is still wide debate as to ho ...

Swarm-bots to the Rescue

Francesco Mondada, Michael Bonani, Roderich Gross

We explore the problem of resource allocation in a system made up of autonomous agents that can either carry out tasks individually or, when necessary, cooperate by forming physical connections with each other. We consider a group transport scenario that i ...

Isolation and evaluation of novel adeno-associated virus sequences from porcine tissues

High antigenic compatibility and low toxicity is associated with xenograft transplantation of porcine tissues in immunodeficient human recipients. We hypothesized that adeno-associated viruses (AAVs) of porcine origin could be highly compatible to human ti ...
