The observational approach is based on direct path measurements of seabed reflection and scattering. The key advantages of this approach are: 1) high resolution vertically, 0.1m and laterally: inner scale of ~10m and outer scale of 100 km; 2) it substantially reduces uncertainties from the space/timevarying oceanography and biology due to short path lengths; 3) it requires a low source level, 4...

A modelling system, PERLE, has been developed at Meteo-France, for the Crisis Meteorological Cell (CMC) of atmospheric accidental release, in case of emergency. Mesoscale meteorological fields are simulated by the nonhydrostatic MESO-NH model (8km and 2km resolution nested grids), that also supply an overview of the plume on a regional scale with an eulerian passive tracer. The dispersion model...

Traditional MEMS actuators have limited stroke and force characteristics. This paper describes the development of a hybrid actuation solution, which utilizes a micro-machined actuator array to provide switching of mechanical motion of a larger mesoscale piezo-electric actuator. One motivating application of this technology is the development of a tactile display, where discrete mechanical actua...

Regional, diurnal and seasonal variations of surface temperature are particularly large on Mars. This is mostly due to the Martian surface remaining close to radiative equilibrium. Contrary to most terrestrial locations, contributions of sensible heat flux (i.e. conduction/convection exchanges between atmosphere and surface) to the surface energy budget [hereinafter SEB] are negligible on Mars ...

We propose a novel measure to assess the presence of meso-scale structures in complex networks. This measure is based on the identification of regular patterns in the adjacency matrix of the network, and on the calculation of the quantity of information lost when pairs of nodes are iteratively merged. We show how this measure is equivalent to standard modularity, but also how it is able to dete...

Multi-scale interactions between initially planar deformation waves in heterogeneous energetic solids and macro-scale boundaries were computationally examined to characterize wave interaction structures and dissipative heating responsible for combustion initiation. The macro-scale response was described by a continuum theory that accounts for elastic and inelastic volumetric deformation in a th...

The space-time dynamics of rigid inhomogeneities (inclusions) free to move in a randomly fluctuating fluid bio-membrane is derived and numerically simulated as a function of the membrane shape changes. Both vertically placed (embedded) inclusions and horizontally placed (surface) inclusions are considered. The energetics of the membrane, as a two-dimensional (2D) meso-scale continuum sheet, is ...
