- Article scientifique
Article scientifique
Le projet Gaume Energies a, entre autres, comme objectif de mettre en place des solutions de stockage décentralisé d’énergie afin d’augmenter au-delà de 60% le taux d’autoconsommation d’énergie d’origine photovoltaïque. Le placement de batteries, de contrôleurs de puissance sur la production d’eau chaude sanitaire et de prises intelligentes pendant deux ans sur deux installations a permis de constater, ...
Analyse de la résistance d’un caisson de vidage horizontal (approche par éléments finis - SPH)

Article scientifique
Afin d'estimer la résistance du caisson d'un nouveau système horizontal de déchargement d’une semi-remorque, deux étapes de simulation ont été réalisées. Tout d'abord, la méthode SPH (Smoothed Particle Hydrodynamic) a simulé le phénomène de décharge et la distribution de la pression de la terre écrasée contre la benne a été récupérée. Ensuite, on a appliqué la distribution de pression extraite de ...

Article scientifique
Understanding neck pain is an important societal issue. Kinematic data from sensors may help to gain insight into the pathophysiological mechanisms associated with neck pain through a quantitative sensorimotor assessment of one patient. The objective of this study was to evaluate the potential usefulness of artificial intelligence with several machine learning (ML) algorithms in assessing neck ...

- Article scientifique
Article scientifique
With the 4th industrial revolution and the increased use of cobots in the industries comes many opportunities for new generation control panels. In this article, we proposed to develop a deep learning model to recognize in real time 10 different gestures that can be used to interact with a cobot. We proposed a new dataset containing gestures that can be used in an industrial context. The videos were ...

- Article scientifique
Article scientifique
Action and activity recognition is essential in the world of cobots to ensure the best efficiency and a safety collaboration between a robot and the human-being. The approach of the article is the creation of a new activity dataset for an industrial context with cobots for recognition. We proposed to use LSTM (Long Short-Term Memory) to analyse and recognize the activities and we also proposed to ...
Comparaison de la rigidité d’un nouveau type de benne par rapport à ceux existants

,
- Article scientifique
Article scientifique
La chute d’une semi-remorque basculante (appelée benne par la suite) est un accident courant dans le milieu de la construction à cause de nombreux facteurs tels que la non-horizontalité du camion, un sol trop meuble ou un déséquilibre de la charge dans la benne. D’une façon générale, si le chargement d’une benne est fortement asymétrique, son déchargement engendrera le déplacement du centre de gravité ...
Electron impact ionization of thymine clusters embedded in superfluid helium droplets

,
- Article scientifique
Article scientifique
Embedding molecules in helium clusters has become a powerful technique for the preparation of cold targets for spectroscopy experiments, as well as for the assembly of complex, fragile molecular species. We have recently developed a helium cluster source and a pick-up cell to produce neutral beams of doped helium droplets, to be used as targets in studies on electron collisions with molecules of ...
Spectroscopy and dynamics of the 7,7,8,8-tetracyanoquinodimethaneradical anion

- Article scientifique
Article scientifique
The photoelectron spectrum of the 7,7,8,8-tetracyanoquinodimethane (TCNQ) radical anion has
been measured at 3.1 eV. Additionally, the ultrafast relaxation dynamics of the first excited state
(12B3u) of TCNQ have been studied using time-resolved photoelectron spectroscopy, which
reveals that it undergoes internal conversion back to the ground state (2B2g) with an associated
lifetime of 650 fs ...
Toward real-time charged-particle image reconstruction using polar onion-peeling

,
- Article scientifique
Article scientifique
A method to reconstruct full three-dimensional photofragment distributions from their two-dimensional (2D) projection onto a detection plane is presented, for processes in which the expanding Newton sphere has cylindrical symmetry around an axis parallel to the projection plane. The method is based on: (1) onion-peeling in polar coordinates [Zhao et al., Rev. Sci. Instrum. 73, 3044 (2002)] in which ...
Electron-impact dissociative ionization of the molecular ion HDO + : A global view

Article scientifique
We present a combined experimental and theoretical study of the fragmentation of HDO2+ molecular ions
produced by electron-impact ionization of HDO+ in the collision energy range 20–2500 eV. Experimental
absolute partial inclusive cross sections for the production of OD+, OH+, and O+ are reported and compared
successfully to theoretical predictions. Ab initio methods are used to calculate the ...
