Subthreshold Jitter in VR Can Induce Visual Discomfort
Visual-vestibular conflicts (VVCs) are a primary contributor to visually induced motion sickness (VIMS) in head-mounted displays (HMDs). Cependant, virtual reality (VR) comfort studies often rely on exposing seated or standing users to experiences with high intensity visual motion (such as roller coasters)....
Solutions par ondes progressives des équations de Burgers-Huxley
We study the traveling wave solutions of the Burgers-Huxley equation from a geometric point of view via the qualitative theory of ordinary differential equations. By using the Poincar\’e compactification we study the global phase portraits of a family of polynomial ordinary differential...
Augmentation de la collecte de données quantiques bruyantes simulées par ordres de Magnitude utilisant l'échantillonnage pré-trajectoire avec exécution par lots
La simulation classique des systèmes quantiques est un défi, as even noiseless $n$-qubit quantum states scale as $2^n$. The complexity of noisy quantum systems is even greater, requiring $2^n \times 2^n$-dimensional density matrices. Diverses approximations réduisent les frais généraux de la matrice de densité, including quantum trajectory-based methods, which instead...
SLiM-Gym: Apprentissage par renforcement pour la génétique des populations
Nous vous présentons SLiM-Gym, a Python package for integrating reinforcement learning (R.L.) avec des simulations génétiques de population à long terme. Wright-Fisher evolutionary dynamics offer a tractable framework for modeling populations across discrete generations, yet applying RL to these systems requires a compatible training environment. SLiM-Gym connects...
Combinatoire énumérative de cohérence temporelle non étiquetée et étiquetée arbres gallés
En phylogénétique mathématique, the time-consistent galled trees provide a simple class of rooted binary network structures that can be used to represent a variety of different biological phenomena. We study the enumerative combinatorics of unlabeled and labeled time-consistent galled trees. We present...
Performances de l'appareil MORA pour tester l'invariance par inversion du temps dans la désintégration bêta nucléaire
The MORA experimental setup is designed to measure the triple-correlation D parameter in nuclear beta decay. The D coefficient is sensitive to possible violations of time-reversal invariance. The experimental configuration consists of a transparent Paul trap surrounded by a detection setup with...
Exosquelette de main orthétique contrôlé par la vision
This paper presents the design and implementation of an AI vision-controlled orthotic hand exoskeleton to enhance rehabilitation and assistive functionality for individuals with hand mobility impairments. The system leverages a Google Coral Dev Board Micro with an Edge TPU to enable real-time...
Paramétrage de la décomposition propre des matrices de pénalités pour une amélioration Conception des contrôles: Applications aérospatiales
Modern control algorithms require tuning of square weight/penalty matrices appearing in quadratic functions/costs to improve performance and/or stability output. En raison de la simplicité du réglage du gain et de l'application d'une définition positive, diagonal penalty matrices are used extensively in control methods such as linear quadratic regulator (LQR),...
Analyser les rayures dans les flux piétons traversant à l'aide de matrices temporelles et un modèle géométrique
Understanding pattern formation in crossing pedestrian flows is essential for analyzing and managing high-density crowd dynamics in urban environments. This study presents two complementary methodological approaches to detect and characterize stripe formations, an emergent structure observed when two pedestrian groups cross at...
Effet de champ térahertz dans un semi-conducteur bidimensionnel MoS2
Couches bidimensionnelles (2D) matériels, with their atomic-scale thickness and tunable electronic, optique, et propriétés mécaniques, open many promising pathways to significantly advance modern electronics. The field effect caused by a strong electric field, généralement du niveau MV/cm, applied perpendicular to the material...
