Séminaire PMMH - Hannah Allen (LSCE, CEA Saclay)
Monitoring atmospheric fossil fuel emissions using radiocarbon and global atmospheric simulations with a transport and inverse modeling system
Independent monitoring and apportioning of CO2 emissions is crucial for the verification of greenhouse gas reductions targeted by international agreements designed for climate change mitigation and adaptation. Radiocarbon (14C), found as a fractional isotope of CO2, can be used as a key tracer for fossil-derived CO2 and thus aid in the accurate apportioning of measured CO2 that arises from fossil fuel sources compared with other emissions sources. As part of the Horizon Europe CORSO project, we expanded a dedicated atmospheric transport modeling and variational inversion system to include radiocarbon in order to assess fossil CO2 emissions estimates at the global scale. The system is based on the assimilation of CO2 and 14CO2 measurements that are collected using central-European atmospheric ICOS stations combined with global background stations. The modeling and inversion framework is based on the Community Inversion Framework (CIF) coupled to the LMDZ global transport model with fluxes and isotopic signatures from terrestrial, oceanic, fossil fuel, nuclear, and cosmogenic sources. We conduct a multi-decadal analysis of the CO2 and 14CO2 emissions derived from this framework.

Vendredi 20 juin de 11h00 à 12h00 - Salle réunion PMMH 1
REPROGRAMMABLE HARDWARE FOR DATA PROCESSING AT THE EDGE : A NEW COMPUTING PARADIGM BASED ON NEUROMORPHIC SYSTEMS
The brain's ability to perform efficient and fault-tolerant data processing is strongly related with its peculiar interconnected adaptive architecture, based on redundant neural circuits interacting at different scales. By emulating the brain's processing and learning mechanisms, computing technologies strive to (…) -

Séminaire PMMH - Salvatore Federico (University of Calgary, Canada)
Vendredi 4 juillet de 11h00 à 12h00 - Salle réunion PMMH 1
Continuum Mechanics of Hydrated Fibre-Reinforced Soft Tissues
Biological tissues can be represented as bi-phasic continua, with a porous solid phase saturated by an interstitial fluid and reinforced by collagen fibers. This lecture will give an overview of the modelling techniques for fibre-reinforced porous composite materials with statistical orientation of the fibers. Both (…) -

Instructions générales pour les conférenciers
Le public du séminaire est très hétérogène (rien qu’au PMMH nous travaillons sur des thématiques très diverses, mécanique des fluides, des milieux granulaires, des solides, physique statistique, physique du mouillage, micro-fluidique, biophysique,...) l’objectif est donc de ne pas faire un séminaire trop spécialiste : au moins la première moitié du séminaire à un niveau accessible pour celui qui ne connaît rien sur le sujet.
Le séminaire a lieu à 11h. rendez-vous 15 minutes avant pour installer et tester la projection.
Le séminaire dure environ 45 minutes pour laisser un peu de temps pour discuter à la fin.
