A B S T R A C T Time-stepping schemes in ocean–atmosphere models can involve multiple time levels. Traditional data assimilation implementation considers only the adjustment of the current state using observations available, i.e. the one time level adjustment. However, one time level adjustment introduces an inconsistency between the adjusted and unadjusted states into the model time integratio...

Purpose To introduce SHERPA-LEAP, a model for the consortial development, population and support of eprints repositories. Design/methodology/approach The organisational and technical structures of the consortium are described, including a brief summary of central and local resource responsibilities. Some positive and negative aspects of a consortial approach to institutional repository developm...

This report focuses on a centered-fluxes discontinuous Galerkin method coupled to a second-order Leap-Frog time scheme for the propagation of electromagnetic waves in dispersive media. After a presentation of the physical phenomenon and the classical dispersion models (particularly the Drude one), a generalized dispersive model is introduced. An a priori stability and convergence study is lead ...

This paper presents a new strategy to deal with the excessive diffusion that standard finite volume methods for compressible Euler equations display in limit of low Mach number. The can be understood as using centered discretizations acoustic part and stabilizing them leap-frog-type (“sequential explicit”) time integration, fully explicit method. integration takes inspiration from time-explicit...
