PULSAR: development of a mirror tile prototype for future large telescopes robotically assembled in space
(2020-12-13)The H2020 project PULSAR (Prototype for an Ultra Large Structure Assembly Robot) development objective is to create three demonstrators that that will pave the way for the construction of large structures in orbit. The ... -
Pulse Oximetry at the Wrist During Sleep: Performance, Challenges and Perspectives
(2020-07)The state-of-the-art non-invasive measurement of peripheral oxygen saturation (SpO2) during sleep is mainly based on pulse oximetry at the fingertip. Although this approach is noninvasive, it can still be obtrusive and ... -
Pulse Wave Analysis of Photoplethysmography Signals to Enhance Classification of Cardiac Arrhythmias
(2022-09)Photoplethysmography (PPG) has recently gained increasing interest for less obtrusive long-term cardiovascular monitoring. As for cardiac arrhythmia (CA), most research and available PPG devices have focused on the detection ... -

Quantifying and Modeling the Impact of Interconnection Failures on the Electrical Performance of Crystalline Silicon Photovoltaic Modules
(2018)We present an electrical model developed with LT SPICE that simulates the performance of a string of cells with disconnections in the electrical circuit. In a previous contribution, we quantified experimentally how the ... -
Quantifying and modeling the impact of interconnection failures on the electrical performance of crystalline silicon photovoltaic modules
(2019)Failures in the metallic interconnections are among the main degradation modes for photovoltaic modules. Fatigue accumulation due to thermomechanical stresses can result in deterioration of the solder joints or in broken ... -
Quantifying competitive grain overgrowth in polycrystalline ZnO thin films
(2019)The grain size evolution of polycrystalline thin films, which form by competitive grain overgrowth as commonly interpreted using the van der Drift model, is understood to follow a power-law scaling of the average grain ... -
Quantifying the potential of smart heat pump control to increase the self consumption of photovoltaic electricity in buildings
(2018)Energy management systems that efficiently use self-produced renewable energy are becoming popular. However, quantifying their benefits in terms of self-consumption increase and associated financial benefits, is difficult ... -
Quantitative Micro-Raman Spectroscopy for Partial Pressure Measurement in Small Volumes
(2017-12-01)We demonstrate the quantitative capabilities of Raman confocal microscopy as a nondestructive method to measure the partial pressure of molecular gases in mm3 range sealed volume having an optical access. Thanks to a ... -
Radiation hard mode-locked laser suitable as a spaceborne frequency comb
(2015-04-20)We report ground-level gamma and proton radiation tests of a passively mode-locked diode-pumped solid-state laser (DPSSL) with Yb:KYW gain medium. A total gamma dose of 170 krad(H2O) applied in 5 days generates minor changes ... -
Raising the one-sun conversion efficiency of III-V/Si solar cells to 32.8% for two junctions and 35.9% for three junctions
(2017)Today''s dominant photovoltaic technologies rely on single-junction devices, which are approaching their practical efficiency limit of 25-27%. Therefore, researchers are increasingly turning to multi-junction devices, which ... -
Real Time Eye Gaze Tracking for Human Machine Interaction in the Cockpit
(2022-03-02)The Aeronautics industry has pioneered safety from digital checklists to moving maps that improve pilot situational awareness and support safe ground movements. Today, pilots deal with increasingly complex cockpit environments ... -
