Tuning the coercive field of strontium M-type hexaferrite nanopowders via pH control

Single-phase strontium M-type hexaferrite (SrFe12O19) nanopowders were successfully synthesized via a citrate precursor sol–gel method. This study investigates the effect of pH variation in the precursor solution on the structural, morphological,…

Ellipsometry of surface acoustic waves using 3D vibrometry for viscoelastic material characterization by the estimation of complex Lamé coefficients versus the frequency

Surface acoustic waves (SAW) are adequate regarding material characterization because they have low geometric attenuation compared to bulk waves. SAW can be generated easily by normal excitation using contact transducers or power lasers and have…

An innovative method for the objective comparison of the performance of active control devices

In the active control literature, the question of how to objectively and comprehensively compare system performance has received little attention. In most cases, comparisons are only made on a paper-specific application and cannot be extended to new…

Analysis of the Timetable Impact on Energy Consumption of a Subway Line

This paper analyzes the timetable impact on the energy consumption of a subway line. In most timetable studies, simplified models are used and can lead to misestimation of the braking energy and thus the energy transfer between braking vehicles and…

Piezoelectric deicing system for aeronautics: Extensional mode actuator and power supply

Recent research shows a growing interest in low‐power avionic deicing systems, in particular, those based on piezoelectric actuators for their energy efficiency. The system generates micrometric vibrations in the structure to delaminate and break…

Robust classification with noisy labels using Venn-Abers predictors

The advent of deep learning methods has led to impressive advances in computer vision tasks over the past decades, largely due to their ability to extract non-linear features that are well adapted to the task at hand. For supervised approaches, data…
