Status of the ALICE CERN Analysis Facility

Marco Meoni

The ALICE experiment at CERN LHC is using a PROOF-enabled cluster for fast physics analysis, detector calibration and reconstruction of small data samples. The current system (CAF - CERN Analysis Facility) consists of some 120 CPU cores and about 45 TB of ...

A Randomized Countermeasure Against Parasitic Adversaries in Wireless Sensor Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Jun Luo

Due to their limited capabilities, wireless sensor nodes are subject to physical attacks that are hard to defend against. In this paper, we first identify a typical attacker, called parasitic adversary, who seeks to exploit sensor networks by obtaining mea ...

Design and implementation of an efficient data stream processing system

Ali Salehi

In standard database scenarios, an end-user assumes that all data (e.g., sensor readings) is stored in a database. Therefore, one can simply submit any arbitrary complex processing in the form of SQL queries or stored procedures to a database server. Data ...

Source coding in sensor networks

Robert Konsbruck

Wireless sensor networks have emerged as versatile tools to monitor the evolution of physical fields over large areas by means of self-powered and low-cost sensing devices. Although their development was originally motivated by military applications, they ...

Microscopic Dual-Regime Model for Single-Lane Roundabouts

Most of microsimulation tools used to model roundabouts encompass classical gap-acceptance algorithms to represent the insertion of approaching vehicles into the circulatory roadway. However, these algorithms fail to reproduce the mean priority sharing pro ...

Graphical display for annual climate-based daylight simulation

Marilyne Andersen, Magali Bodart

Due to daylight variability, a design cannot be thoroughly assessed using single-moment simulations, which is why we need dynamic performance metrics like Daylight Autonomy and Useful Daylight Illuminance. Going one step further, the annual variation in pe ...

SensorScope: Out-of-the-Box Environmental Monitoring

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, François Ingelrest, Olivier Couach

An important field of application for wireless sensor networks is environmental monitoring. Given the importance of potential climate changes, environmental impact on cities, and pollution, it is an application domain where sensor networks can have great i ...

Assessing the Challenges of Environmental Signal Processing through the SensorScope Project

Martin Vetterli, Yue Lu, Guillermo Barrenetxea Kobas, François Ingelrest

SensorScope is a collaborative project between network, signal processing, and environmental researchers that aims at providing a cheap and out-of-the-box environmental monitoring system based on a wireless sensor network. It has been successfully used in ...
