Brightness and contrast corrections for stereocorrelation: Global and instantaneous formulation with spatial regularization

Stereocorrelation (SC) is a versatile experimental method increasingly used to measure 3D surface displacements in complex mechanical tests. However, convergence issues may arise when gray-level conservation is no longer validated, particularly when…

Historical pyrite “mirrors” from the Ecuadorian Cañari culture, digital microscopy observations, mineralogical and elemental analysis

This research relies on microscopy and digital microscopy observations and spectral analysis techniques: Raman spectroscopy, laser-induced breakdown spectroscopy (LIBS) and particle-induced X-ray emission (PIXE), to recover part of the lost identity…

Study of Rayleigh waves interaction with a spherical ball in contact with a plane surface for the development of new NDT method for ball bearings

The monitoring of the integrity of the spherical balls inside a ball bearing can be challenging, as it needs to be disassembled in order to access every element of the structure. In this paper, an ultrasonic method is used to directly interrogate…

InfraParis: A multi-modal and multi-task autonomous driving dataset

Current deep neural networks (DNNs) for autonomous driving computer vision are typically trained on specific datasets that only involve a single type of data and urban scenes. Consequently, these models struggle to handle new objects, noise,…

Effects of Filtering and Current-angle Adjustment on the Multi-Material Topology Optimization of a 3-phase Stator

This paper investigates MMTO methods to design 3-phase PMSM stators, showing that a usual gradient descent leads to non-manufacturable local optima. A multi-material density filtering consistent with the antiperiodic boundary conditions smooths the…

Renewable Energy in Data Centers: the Dilemma of Electrical Grid Dependency and Autonomy Costs

Integrating larger shares of renewables in data centers' electrical mix is mandatory to reduce their carbon footprint. However, as they are intermittent and fluctuating, renewable energies alone cannot provide a 24/7 supply and should be combined…
