Unsteady Aerodynamics and Adjoint Method

open access: yes, 2011
Cette thèse contribue à la simulation numérique des écoulements d'un fluide compressible modélisé par les équations de Euler et Navier-Stokes: étude d'un schéma d'ordre élévé basé sur une matrice de masse, modélisation des écoulement turbulents compressibles à très haut Reynolds, développement des estimateurs et correcteurs d'erreurs a posteriori et a ...

Computing Bonds Between Formal Contexts

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 11, Page 11661-11677, 30 July 2026.
ABSTRACT The notion of bond was introduced as a technique to aggregate information from multiple datasets without modifying the information already present in each of the datasets. This notion has been extended to several fuzzy frameworks, including the residuated lattice setting, which we also consider in this paper.

A Matrix‐Free, Scalable, and Robust Implicit Material Point Method

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT An implicit material point method is presented using a new dynamic relaxation solver, allowing for a simple and efficient quasi‐static formulation that may be readily implemented in existing explicit‐dynamic codes. The use of dynamic relaxation and aggregation is shown to produce an extremely robust material point method scheme, with good ...

Advancing Aquifer Characterization Through the Integration of Satellite Geodesy, Geomechanics, and Bayesian Inference

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Unsustainable rates of groundwater (GW) depletion make GW management a priority. Effective GW management is hindered by the uncertainty in the predictions of aquifer models, but the increase of geodetic surface deformation data can improve aquifer characterization.

Mass Loss From Thwaites Glacier Continues Even Without Ocean Melting

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Pine Island and Thwaites glaciers dominate Antarctica's sea‐level contribution. However, it remains unclear whether their ice loss is driven by anomalously warm present‐day ocean conditions, perhaps linked to anthropogenic climate change, or are an ongoing response to historical natural climate anomalies.

Suppressing Stitching Errors in Full‐Sensor‐Plane Color Routers via Optical Structural Similarity

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
Angle‐specific nanophotonic color routers are assembled from a library of inverse‐designed unit cells matched to local incidence angles. Optical structural similarity (OSS) constrains neighboring permittivity profiles during optimization, suppressing inter‐cell stitching errors without additional full‐wave simulations and enabling oblique‐incidence ...
