Efficient Object Placement Including Node Selection in a Distributed Virtual Machine

Currently, software engineering is becoming even more complex due to distributed computing. In this new context, portability while providing the programmer with the single system image of a classical Java Virtual Machine (JVM) is one of the key issues. Hen ...

A Reconfigurable Network-on-Chip Architecture for Optimal Multi-Processor SoC Communication

Giovanni De Micheli, David Atienza Alonso

Network-on-Chip (NoC) has emerged as a very promising paradigm for designing scalable communication architecture for Systems on Chips (SoCs). However, NoCs designed to fulfill the bandwidth requirements between the cores of an SoC for a certain set of runn ...

Understanding the Potential Impact of Multiple Robots in Odor Source Localization

Alcherio Martinoli, Thomas Lochmatter

We investigate the performance of three bio-inspired odor source localization algorithms used in non-cooperating multi-robot systems. Our performance metric is the distance overhead of the first robot to reach the source, which is a good measure for the sp ...

Tracking an Odor Plume in a Laminar Wind Field with the Crosswind-Surge Algorithm

Alcherio Martinoli, Thomas Lochmatter

We introduce a novel bio-inspired odor source localization algorithm (surge-cast) for environments with a main wind flow and compare it to two well- known algorithms. With all three algorithms, systematic experiments with real robots are carried out in a w ...

Simulation Experiments with Bio-Inspired Algorithms for Odor Source Localization in Laminar Wind Flow

Alcherio Martinoli, Thomas Lochmatter

We compare three bio-inspired odor source localization algorithm (casting, surge-spiral and surge-cast) for environments with a main wind flow in simulation. The wind flow is laminar and the simulation setup similar to the setup in the wind tunnel in which ...

Designing Routing and Message-Dependent Deadlock Free Networks on Chips

Giovanni De Micheli, David Atienza Alonso, Luca Benini, Srinivasan Murali, Federico Angiolini

Networks on Chip (NoC) has emerged as the paradigm for designing scalable communication architecture for Systems on Chips (SoCs). Avoiding the conditions that can lead to deadlocks in the network is critical for using NoCs in real designs. Methods that can ...

Microstructuring of polystyrene surfaces with nonsolvent sessile droplets

Ramon Pericet Camara

Herein, we study the microstructuring of toluene-vapor-softened polystyrene surfaces with nonsolvent sessile droplets. Arrays of microvessels are obtained by depositing non-evaporating droplets of ethylene glycol/water on the original polystyrene surfaces ...

A single nanotrench in a palladium microwire for hydrogen detection

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Oscar Vazquez Mena, Thomas Kiefer

The hydrogen sensing characteristics of a single nanotrench fabricated by focused ion beam milling (FIB) in an evaporated palladium microwire are presented. In situ atomic force microscopy (AFM) measurements proved that, in the presence of H2, the trench c ...

Comparative performance of medium voltage overhead distribution lines designs submitted to induced voltages

Mario Paolone, Carlo Alberto Nucci

The aim of this paper is to present the results of the performance study of medium voltage overhead distribution lines against lightning discharges, in the way to define methodologies to reduce the system failures. The results are obtained within the partn ...

On the Cost of Modularity in Atomic Broadcast

André Schiper, Sergio Mena, Nils Richard Ekwall, Olivier Rütti

Modularity is a desirable property of complex software systems, since it simplifies code reuse, verification, maintenance, etc. However, the use of loosely coupled modules introduces a performance overhead. This overhead is often considered negligible, but ...
