Cybercosm: New Foundations for a Converged Science Data Ecosystem
Mark Asch, François Bodin, Micah Beck +4
Scientific communities naturally tend to organize around data ecosystems created by the combination of their observational devices, their data repositories, and the workflows essen…
Self-similarity of low-frequency earthquakes
Mariano Supino, Natalia Poiata, Gaetano Festa +3
Low-frequency earthquakes are a particular class of slow earthquakes that provide a unique source of information on the mechanical properties of a subduction zone during the prepar…
VERCE delivers a productive e-Science environment for seismology research
Malcolm Atkinson, Michele Carpené, Emanuele Casarotti +18
The VERCE project has pioneered an e-Infrastructure to support researchers using established simulation codes on high-performance computers in conjunction with multiple sources of…
New insights on numerical error in symplectic integration
Hugo Jiménez-Pérez, Jean-Pierre Vilotte, Barbara Romanowicz
We implement and investigate the numerical properties of a new family of integrators connecting both variants of the symplectic Euler schemes, and including an alternative to the c…
On the Poincaré's generating function and the symplectic mid-point rule
Hugo Jiménez-Pérez, Jean-Pierre Vilotte, Barbara Romanowicz
The use of Liouvillian forms to obtain symplectic maps for constructing numerical integrators is a natural alternative to the method of generating functions, and provides a deeper…
Memory of the Unjamming Transition during Cyclic Tiltings of a Granular Pile
Stephanie Deboeuf, Olivier Dauchot, Lydie Staron +2
Discrete numerical simulations are performed to study the evolution of the micro-structure and the response of a granular packing during successive loading-unloading cycles, consis…
Multiscale Analysis of the Stress State in a Granular Slope in Transition to Failure
Lydie Staron, Jean-Pierre Vilotte, Farhang Radjai
By means of contact dynamics simulations, we analyze the stress state in a granular bed slowly tilted towards its angle of repose. An increasingly large number of grains are overlo…
Pre-avalanche instabilities in a granular pile
Lydie Staron, Jean-Pierre Vilotte, Farhang Radjai
We investigate numerically the transition between static equilibrium and dynamic surface flow of a 2D cohesionless granular system driven by a continuous gravity loading. This tran…
