From Human-Systems Integration to Human-Systems Inclusion for Use-Centred Inclusive Manufacturing Control Systems

The paper discusses about human-systems inclusion as a new way to take into account human factors on systems engineering. This process applies not only principles from human-supported by automation but also those on automation-supported by human to…

A Diffeomorphic Vector Field Approach to Analyze the Thickness of the Hippocampus from 7T MRI

OBJECTIVE. 7-Tesla MRI of the hippocampus enhances the visualization of its internal substructures. Among these substructures, the cornu Ammonis and subiculum form a contiguous folded ribbon of gray matter. Here, we propose a method to analyze local…

Description of participants in the "Atout Age Mobility" prevention workshops at the University Hospital Center of La Réunion : a prospective study

Introduction As the population ages, loss of autonomy is becoming a priority public health issue. "Atout Age Mobility" prevention interventions for seniors aim to limit frailty, which is a predictive and reversible factor in the loss of autonomy and…

Detection of methane plumes in hyperspectral images from SENTINEL-5P by coupling anomaly detection and pattern recognition

Reducing methane emissions is essential to tackle climate change. Here, we address the problem of detecting large methane leaks using hyperspectral data from the Sentinel-5P satellite. For that we exploit the fine spectral sampling of Sentinel-5P…

New preconditioners for the Laplace and Helmholtz integral equations on open curves: analytical framework and numerical results

Helmholtz wave scattering by open screens in 2D can be formulated as first-kind integral equations which lead to ill-conditioned linear systems after discretization. We introduce two new preconditioners in the form of square-roots of on-curve…

Hypocoercivity of Piecewise Deterministic Markov Process-Monte Carlo

In this paper we derive spectral gap estimates for several Piecewise Deterministic Markov Processes, namely the Randomized Hamiltonian Monte Carlo, the Zig-Zag process and the Bouncy Particle Sampler. The hypocoercivity technique we use, presented…

Constrained prediction time random forests using equivalent trees and genetic programming: application to fall detection model embedding

Budgeted learning is a research field of growing interest that aims at including real world resource constraints into the design of machine learning models, for instance to reduce real environment prediction time. One family of method to do so…
