Block-Additive Gaussian Processes under Monotonicity Constraints

Mathis Deronzier, Andrés F. López-Lopera, François Bachoc, Olivier Roustant, Jérémy Rohmer

We generalize the additive constrained Gaussian process framework to handle interactions between input variables while enforcing monotonicity constraints everywhere on the input space. The block-additive structure of the model is particularly suitable in the presence of interactions, while…

Mathematical modeling of iron oxidation in aqueous environment: when kinetics meets thermodynamics

Christian Bataillon, Clément Cancès, Claire Chainais-Hillairet, Federica Raimondi, Juliette Venel

We propose a one-dimensional model for the evolution at mesoscopic scale of a magnetite/maghemite oxide layer at the surface of iron metal set in an aqueous environment. The model takes into account the convection and diffusion of three charge carriers -iron cations, electrons in the conduction…

Des mathématiques comme en l'an 500 : découvrir les suites numériques dans l'Institution Arithmétique de Boèce

Francois Goichot

Dans l’histoire des mathématiques, Boèce est l’un des très rares noms qui s’insèrent entre l’antiquité grecque et l’essor arabe, dans ce haut Moyen Âge qu’on voit souvent comme une période sombre pour la science. Nous proposons quelques éclairages sur les mathématiques de Boèce, telles que nous les…

Carleman-Based Reconstruction Algorithm on a wave Network

Lucie Baudouin, Maya de Buhan, Emmanuelle Crépeau, Julie Valein

In the context of a network of vibrating strings, modelled by interconnected linear partial differential equations, we are interested in the reconstruction of a zeroth order term of each one-dimensional wave equation involved, using some appropriate external boundary measurements. More precisely,…

Estimation of the asymptotic variance matrix of the least squares estimator of weak FARIMA models

Yacouba Boubacar Mainassara, Youssef Esstafa

In this article, we propose a consistent estimator for the asymptotic variance matrix of the least squares estimator in Fractionally AutoRegressive Integrated Moving‐Average (FARIMA) models. Our approach allows for error terms that are uncorrelated, but not necessarily independent. Modified…

Smart piezoelectric energy harvesting: how topology-optimized cavities boost performance in BaTiO 3 multilayer structures

Najoua Fangachi, Mohamed Rguiti, Madiha Yessari, Abdelowahed Hajjaji

Abstract The escalating global energy demand and environmental challenges underscore the urgent need for efficient, sustainable energy-harvesting solutions. In this study, we present a lead-free multilayer piezoelectric energy harvester, termed Arcade Sensor A, fabricated from BaTiO 3 ceramics and…

Improving mechanical stability of SBA-15 monoliths prepared from polymeric scaffolds replication using bentonite clay

Ridvan Yildiz, Jérémy Dhainaut, Carmen Ciotonea, Jean-Philippe Dacquin, Sébastien Royer, Christian Courtois, Yannick Lorgouilloux

The preparation of porous yet mechanically stable centimetric monoliths remains challenging using traditional methods. Herein, hierarchical SBA-15-based porous monoliths, with three levels of porosity (micro- and mesopores from the pores arrangement of the silica structure, and macropores from the…
