Théorie des systèmes. Une approche moderne 1

La théorie des systèmes dynamiques est traitée conformément à l'approche "moderne", héritière de l'analyse algébrique, qui s'est imposée depuis la dernière décennie du XXe siècle. Après un rappel sur l'évolution de la représentation des systèmes…

Microstructural evolution during the crack propagation at the bond-wire contact area of IGBT power modules upon power cycling

This paper proposes an analysis for the main microstructural changes at the chip topside level in the metallic interconnections of SKIM63 IGBT power modules due to aging processes caused by power cycling. The objective is to correlate these changes…

Multi-material topology optimization using Wachspress interpolations for designing a 3-phase electrical machine stator

This work uses multi-material topology optimization (MMTO) to maximize the average torque of a 3-phase permanent magnet synchronous machine (PMSM). Eight materials are considered in the stator: air, soft magnetic steel, three electric phases, and…

Fast Computational Dynamic Model of Traction Drive for Electric Vehicles

To reduce the time-to-market of electric vehicles, fast and accurate energetic simulations are needed. This paper aims to propose a fast computational dynamic model that allows a good compromise between accuracy and computation time while respecting…

A stereo vision geometric descriptor for place recognition and its GPU acceleration for autonomous vehicles applications

In this paper we present a geometric global descriptor dedicated for place recognition in autonomous vehicles applications that is based on stereo camera generated point clouds. We first present the approach used to record the 3D structure of the…

Optimal energy management of offshore wind farms considering the combination of overplanting and dynamic rating

The electricity cost from offshore wind turbines has significantly declined over the past decade. However, in the context of energy transition, the further reduction in electricity generation costs remains a forefront subject. One possibility is to…

Detection of alterations in historical violins with optical monitoring

Preventive conservation is the constant monitoring of the state of conservation of an artwork to reduce the risk of damage in order to minimise the necessity of restorations. Many methods have been proposed to achieve this goal, generally including…
