Invariance de jauge dynamique de la mécanique statistique
We investigate gauge invariance against phase space shifting in nonequilibrium systems, as represented by time-dependent many-body Hamiltonians that drive an initial ensemble out of thermal equilibrium. The theory gives rise to gauge correlation functions that characterize spatial and temporal inhomogeneity with microscopic...
Réduction de dimensionnalité non linéaire interprétable à l'aide de la gaussienne transformation linéaire pondérée
Dimensionality reduction techniques are fundamental for analyzing and visualizing high-dimensional data. With established methods like t-SNE and PCA presenting a trade-off between representational power and interpretability. This paper introduces a novel approach that bridges this gap by combining the interpretability of linear...
SAPO-RL: Optimisation du placement des actionneurs séquentiels pour le fuselage Assemblage via apprentissage par renforcement
Precise assembly of composite fuselages is critical for aircraft assembly to meet the ultra-high precision requirements. En raison des variations dimensionnelles, il y a un espace lorsque deux fuselages s'assemblent. En pratique, actuators are required to adjust fuselage dimensions by applying forces to specific...
De la rugosité de surface à la formation de cratères en 2D multi-échelle simulation d'ablation laser à impulsions ultracourtes
La rugosité de la surface joue un rôle essentiel dans l'ablation laser à impulsions ultracourtes, en particulier pour les applications industrielles utilisant des opérations en mode rafale, traitement laser multi-impulsions, and the generation of laser-induced periodic surface structures. Ainsi, we address the impact of surface roughness on the resulting laser...
Dynamique résolue en temps des polaritons du guide d'ondes GaN
We implement a new experimental approach to directly measure the lifetime of guided polaritons arising from the strong-coupling of GaN excitons and the guided photonic modes of a slab waveguide. Utilisation d'une configuration d'imagerie de Fourier, combiné à un filtrage spatial de l'émission,...
Le Cauchy–Szegö Projection for domains in $\mathbb C^n$ with minimal smoothness: théorie pondérée
Let $D\subset\mathbb C^n$ be a bounded, strongly pseudoconvex domain whose boundary $bD$ satisfies the minimal regularity condition of class $C^2$. UN 2017 result of Lanzani \& Stein déclare que le Cauchy–Szeg\”{o} projection $S_\omega$ defined with respect to a bounded, positive continuous multiple...
TarDiff: Guidage de diffusion orienté vers la cible pour l’électronique synthétique Génération de séries chronologiques de dossiers de santé
Dossier de santé électronique synthétique (DSE) time-series generation is crucial for advancing clinical machine learning models, as it helps address data scarcity by providing more training data. Cependant, most existing approaches focus primarily on replicating statistical distributions and temporal dependencies of real-world data....
Boulon: Habiller des personnages virtuels à grande échelle
Habiller les personnages virtuels est un processus long et souvent manuel. Les tenues peuvent être composées de plusieurs vêtements, and each garment must be fitted to the unique shape of a character. Since characters can vary widely in size and shape, fitting outfits to...
Partitionnement de graphiques multiniveaux en temps linéaire via la sparsification des bords
The current landscape of balanced graph partitioning is divided into high-quality but expensive multilevel algorithms and cheaper approaches with linear running time, tels que les algorithmes à un seul niveau et les algorithmes de streaming. We demonstrate how to achieve the best of both worlds with a \emph{linear...
