GNSS/INS Kalman Filter Integrity Monitoring with Uncertain Time Correlated Error Processes
Safety-critical navigation applications require that estimation errors be reliably quantified and bounded. Over the last decade, significant effort has been put to guarantee a bounded position estimation by using Global Navigation Satellite Systems (GNSS) ...
EPFL2022Rocker oscillator time bases
Simon Nessim Henein, Ilan Vardi
Since the invention of the pendulum clock by Christiaan Huygens in 1657, precision timekeepers have been regulated by oscillators. Although the pendulum is not an isochronous oscillator, its introduction as a time basis for clock regulation led to a signif ...
2021Time-Synchronization Attack Detection in Unbalanced Three-Phase Systems
Jean-Yves Le Boudec, Mario Paolone, Marguerite Marie Nathalie Delcourt, Gyorgy Miklos Dan
Phasor measurement units (PMU) rely on an accurate time-synchronization to phase-align the phasors and timestamp the voltage and current phasor measurements. Among the symmetrical components computed from the phasors in three-phase systems, the standard pr ...
2021A Low Power Multi-Class Migraine Detection Processor Based on Somatosensory Evoked Potentials
Mahsa Shoaran, Bingzhao Zhu, Zain Taufique
Migraine is a disabling neurological disorder that can be recurrent and persist for long durations. The continuous monitoring of the brain activities can enable the patient to respond on time before the occurrence of the approaching migraine episode to min ...
2021TDOA Source-Localization Technique Robust to Time-Synchronization Attacks
Jean-Yves Le Boudec, Marguerite Marie Nathalie Delcourt
In this paper, we focus on the localization of a passive source from time difference of arrival (TDOA) measurements. TDOA values are computed with respect to pairs of fixed sensors that are required to be accurately time-synchronized. This constitutes a we ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Time-Synchronization Attacks against Critical Infrastructures and their Mitigation
Marguerite Marie Nathalie Delcourt
This work focuses on the security of critical infrastructures against time-synchronization attacks (TSA). A TSA can impact any network that relies on the dynamic analysis of data, by altering the time synchronization between its nodes. Such attacked networ ...
EPFL2021Shaking force balancing of a 2-DOF isotropic horological oscillator
Simon Nessim Henein, Hubert Pierre-Marie Benoît Schneegans, Etienne Frédéric Gabriel Thalmann
Despite centuries of research and significant advances, the escapement mechanism used to count and maintain oscillations of mechanical time bases remains a complex mechanism and a major source of energy losses. We showed in previous work that, instead of t ...
2021On Time Synchronization Issues in Time-Sensitive Networks with Regulators and Nonideal Clocks
Jean-Yves Le Boudec, Ludovic Bernard Gérard Thomas
Flow reshaping is used in time-sensitive networks (as in the context of IEEE TSN and IETF Detnet) in order to reduce burstiness inside the network and to support the computation of guaranteed latency bounds. This is performed using per-flow regulators (suc ...
Association for Computing Machinery2020Application of a Low Frequency, Low Power Radio Frequency Positioning System for Real Time Indoor Positioning
Yves Perriard, Alexis Boegli, Pooneh Mohaghegh
This paper focuses on the design and application of low power and low-frequency localization system using received signal strength indication (RSSI). The receiver will wake up from sleeping mode by a modulated magnetic field emitted from a transmitter modu ...
2020Remote Sensing meets Deep Learning: Exploiting Spatio-Temporal-Spectral Satellite Images for Early Wildfire Detection
Wildfires are getting more severe and destructive. Due to their fast-spreading nature, wildfires are often detected when already beyond control and consequently cause billion-scale effects in a very short time. Governments are looking for remote sensing me ...
