Predictive sensitivity analysis of motor’s windings HF impedances

This paper describes a process in which high frequency (HF) differential-mode (DM) and common-mode (CM) impedances of a Permanent Magnet Synchronous Motor (PMSM) are predicted. These tools, using both 2D Finite Element Modeling (FEM) and Spice…

Modeling random conductor distribution in stator winding slots: impact on common and differential-mode impedances

This paper presents a unified methodology for modeling the Common Mode (CM) and Differential Mode (DM) impedances of a permanent magnet synchronous motor. It combines finite element (FE) modeling methodologies with Spice-type discrete-parameter…

On the use of molecular dynamics to compute the dielectric permittivity of C-S-H

Multiscale modeling of the dielectric response of cement-based materials requires the intrinsic permittivity of the constituent phases, particularly calcium silicate hydrates (C-S-H), which is the major hydrated phase in concrete. In this study, a…

Uncertainty quantification for vision regression tasks

This work focuses on uncertainty quantification for deep neural networks, which is vital for reliability and accuracy in deep learning. However, complex network design and limited training data make estimating uncertainties challenging. Meanwhile,…

Le testament de Stephen Hawking

L'idée que les lois de la physique et que des grandeurs longtemps considérées comme universelles telles que le temps et l'espace puissent avoir une histoire, voire des origines, hante la physique, surtout depuis 1915.
