Reducing Time Complexity in RFID Systems

Gildas Avoine, Philippe Oechslin, Etienne Dysli

Radio frequency identification systems based on low-cost computing devices is the new plaything that every company would like to adopt. Its goal can be either to improve the productivity or to strengthen the security. Specific identification protocols base ...

Writer Identification for Smart Meeting Room Systems

Samy Bengio, Jonas Richiardi

In this paper we present a text independent on-line writer identification system based on Gaussian Mixture Models (GMMs). This system has been developed in the context of research on Smart Meeting Rooms. The GMMs in our system are trained using two sets of ...

Magnetic direct generation of acoustic resonances in silicon membranes

Nico de Rooij

High-Q silicon membranes have been fabricated as resonator elements for excitation by magnetic direct generation of acoustic waves. Operating in the thickness shear mode, these inexpensive sensor elements are remotely excited by a planar spiral coil, drive ...

Methodology for process energy analysis: application to a sulfite wood pulping

François Maréchal, Zoé Périn-Levasseur

Creating a consistent thermodynamic database is the first step required to perform a process integration study. A method based on the use of data identification and reconciliation has been developed to model the mass and the energy balances of a pulp and p ...

Cryptography in radio frequency identification and fair exchange protocols

Gildas Avoine

This PhD thesis focuses on fair exchange protocols and radio frequency identification protocols. Fair exchange stems from a daily life problem: how can two people exchange objects (material or immaterial) fairly, that is, without anyone being hurt in the e ...

Radio Frequency Identification: Adversary Model and Attacks on Existing Protocols

Gildas Avoine

Radio Frequency Identification (RFID) systems aim to identify objects in open environments with neither physical nor visual contact. They consist of transponders inserted into objects, of readers, and usually of a database which contains information about ...

Probe measurements of plasma potential nonuniformity due to edge asymmetry in large-area radio-frequency reactors: The telegraph effect

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens, Hannes Schmidt, Lukas Derendinger

In large-area radio-frequency (rf) capacitive reactors, the redistribution of rf current to maintain current continuity near asymmetric sidewalls causes a perturbation in rf plasma potential to propagate along the resistive plasma between capacitive sheath ...

Remotely powered addressable UHF RFID integrated system

Catherine Dehollain, Michel Declercq, Jari-Pascal Curty

This paper presents a fully integrated remotely powered and addressable radio frequency identification (RFID) transponder working at 2.45 GHz. The achieved operating range at 4 W effective isotropically radiated power (EIRP) base-station transmit power is ...
