Optimal Design of High-Speed Electric Machines for Electric Vehicles: A Case Study of 100 kW V-Shaped Interior PMSM

The need of compact machines increased in recent years due to increases in raw materials’ price. Hence, many studies are currently being conducted on high-speed challenges to propose an optimal design methodology. AC losses in windings are often not…

Cristallography

Three-phase material mapping with incomplete X-ray diffraction spectral information

An equiatomic nickel–titanium shape-memory alloy specimen subjected to a uniaxial tensile load undergoes a two-step phase transformation under stress, from austenite (A) to a rhombohedral phase (R) and further to martensite (M) variants. The pseudo…

PeakForce AFM Analysis Enhanced with Model Reduction Techniques

PeakForce quantitative nanomechanical AFM mode (PF-QNM) is a popular AFM technique designed to measure multiple mechanical features (e.g., adhesion, apparent modulus, etc.) simultaneously at the exact same spatial coordinates with a robust scanning…

De la sensibilité accélérométrique des oscillateurs optoélectroniques à la mesure dynamique de déformations dans les fibres optiques

Optoelectronic oscillators (OEO) are an alternative solution to traditional quartz oscillators for high purity frequency references generation. For the most demanding applications, the phase noise performances must be kept in harsh vibration…

Détermination des mécanismes de dégradation de poumons humains sous chargement de blast et critères lésionnels associés

Lung damage is the leading cause of death in the face of a blast. For protection purposes, it is essential to understand the causes of this damage. For the moment, the effects of this shock wave on the lungs are poorly described. Indeed, in the…

Étude de la cinétique de séchage des bétons : Application à l'atteinte d'un gradient hydrique représentatif dans le cadre des essais au feu

Spalling of concrete is one form of the thermal instability induced by fire exposure. It needs to be investigated when the fire behaviour of structures is to be assessed.Fire behaviour is commonly assessed by reference to the requirements of NF EN…
