Localizing the Source of an Epidemic Using Few Observations

Brunella Marta Spinelli

Localizing the source of an epidemic is a crucial task in many contexts, including the detection of malicious users in social networks and the identification of patient zeros of disease outbreaks. The difficulty of this task lies in the strict limitation ...

Physical Design Considerations of One-level RRAM-based Routing Multiplexers

Giovanni De Micheli, Xifan Tang, Pierre-Emmanuel Julien Marc Gaillardon, Edouard Giacomin

Resistive Random Access Memory (RRAM) technology opens the opportunity for granting both high-performance and low- power features to routing multiplexers. In this paper, we study the physical design considerations related to RRAM- based routing mult ...

Tackling the Bottleneck of Delay Tables in 3D Ultrasound Imaging

Giovanni De Micheli, Luca Benini, Federico Angiolini, Marcel Arditi, Aya Mohamed Naguib Ahmed Ibrahim

3D ultrasound imaging is quickly becoming a refer- ence technique for high-quality, accurate, expressive diagnostic medical imaging. Unfortunately, its computation requirements are huge and, today, demand expensive, power-hungry, bulky processing resources ...

Sensing the real world : inverse problems, sparsity and sensor placement

Juri Ranieri

A sensor is a device that detects or measures a physical property and records, indicates, or otherwise responds to it. In other words, a sensor allows us to interact with the surrounding environment, by measuring qualitatively or quantitatively a given phe ...

Variable delay using stationary and localized Brillouin dynamic gratings

Luc Thévenaz, Nikolay Primerov

Reflections from movable, dynamic acoustic gratings in polarization maintaining (PM) fibers are employed in the long variable delay of periodic, isolated pulses. The gratings are introduced by stimulated Brillouin scattering (SBS) interaction between two c ...

Understanding and Tackling the Root Causes of Instability in Wireless Mesh Networks

Patrick Thiran, Adel Aziz, David Starobinski

We investigate, both theoretically and experimentally, the stability of CSMA-based wireless mesh networks, where a network is said to be stable if and only if the queue of each relay node remains (almost surely) finite. We identify two key factors that imp ...

Energy Efficient Offloading of 3G Networks

Jean-Yves Le Boudec, Nikodin Ristanovic

A huge increase in the amount of data consumed by smartphone users is becoming a serious problem for mobile operators. In three years, mobile data traffic in the AT&T's network rose 5000%. The US operators invest 50 billion dollars in their data networks e ...

Network coding node placement for delay minimization in streaming overlays

Pascal Frossard, Nikolaos Thomos, Nicolae Cleju

Network coding has been proposed recently as an efficient method to increase network throughput by allowing network nodes to combine packets instead of simply forwarding them. However, packet combinations in the network may increase delay, complexity and e ...

Latency-aware Leader Election

André Schiper, Martin Hutle, Nuno Filipe de Sousa Santos

Experimental studies have shown that electing a leader based on measurements of the underlying communication network can be beneficial. We use this approach to study the problem of electing a leader that is eventually not only correct (as aptured by the fa ...

Complete compensation of pulse broadening in an amplifier-based slow light system using a nonlinear regeneration element

Luc Thévenaz, Sang Hoon Chin

We experimentally demonstrate complete compensation of pulse broadening in an amplifier-based slow light system. The configuration of the delay line basically consists of two stages: a conventional Brillouin slow light system and a nonlinear regeneration e ...
