Variability in soil heat flux from a mesquite dune site
For many natural and agricultural landscapes, vegetation partially covers the ground surface, resulting in significant variations in soil heat flux between interspace areas and underneath vegetation. This is particularly apparent in arid and semiarid regions where vegetation cover is low and clustered or ‘clumped’ with large areas of exposed soil. Surface heterogeneity presents significant chal...
متن کاملProtection des flux audiovisuels MPEG-4 transportés sur internet
RÉSUMÉ. Le transport de contenus multimédia codés au standard MPEG-4 sur Internet est soumis à des contraintes de débit, de délai et de fiabilité. La charge et la nature du trafic sur le réseau ont des effets sur les pertes et les délais d’acheminement des paquets qui doivent être contrôlés. Dans cet article, nous proposons une technique de protection des objets audiovisuels (AVO) adaptée aux c...
متن کاملExtending DUNE: The dune-xt modules
We present our effort to extend and complement the core modules of the Distributed and Unified Numerics Environment DUNE (http://dune-project.org) by a well tested and structured collection of utilities and concepts. We describe key elements of our four modules dune-xt-common, dune-xt-grid, dune-xt-la and dune-xt-functions, which aim at further enabling the programming of generic algorithms wit...
متن کاملModelling a Dune Field
We present a model to describe the collective motion of barchan dunes in a field. Our model is able to reproduce the observation that a typical dune stays confined within a stripe. We also obtain some of the pattern structures which ressemble those observed from aerial photos which we do analyse and compare with the specific field of Laâyounne.
