Hydrodynamics of Monolayer Domains at the Air-Water Interface

open access: yes, 1996
Molecules at the air-water interface often form inhomogeneous layers in which domains of different densities are separated by sharp interfaces. Complex interfacial pattern formation may occur through the competition of short- and long-range forces acting

Influence of the Dufour effect on convection in binary gas mixtures

open access: yes, 1995
Linear and nonlinear properties of convection in binary fluid layers heated from below are investigated, in particular for gas parameters. A Galerkin approximation for realistic boundary conditions that describes stationary and oscillatory convection in ...

Competition between Spiral-Defect Chaos and Rolls in Rayleigh-Benard Convection

open access: yes, 1997
We present experimental results for pattern formation in Rayleigh-Benard convection of a fluid with a Prandtl number, Pr~ 4. We find that the spiral-defect-chaos (SDC) attractor which exists for Pr~1 has become unstable.

Solitons in anharmonic chains with ultra-long-range interatomic interactions

open access: yes, 1999
We study the influence of long-range interatomic interactions on the properties of supersonic pulse solitons in anharmonic chains. We show that in the case of ultra-long-range (e.g., screened Coulomb) interactions three different types of pulse solitons ...

Évolution des stocks de carbone en fonction des trajectoires de gestion en zone humide

open access: yesSciences, Eaux & Territoires, 2018
Plans de gestion et études d'impact devraient dorénavant inclure les services écosystémiques (SE). Face au changement climatique, la régulation du climat global par le stockage de carbone par les écosystèmes est un SE au cœur des préoccupations. C'est un

GNSS Spoofing Detection by Supervised Machine Learning with Validation on Real-World Meaconing and Spoofing Data—Part II

open access: yesSensors, 2020
Global Navigation Satellite System (GNSS) meaconing and spoofing are being considered as the key threats to the Safety-of-Life (SoL) applications that mostly rely upon the use of open service (OS) signals without signal or data-level protection. While a
