Zenith seminar: Ji Liu “Efficient Uncertainty Analysis of Very Big Seismic Simulation Data ” 6 dec. 2017

Efficient Uncertainty Analysis of Very Big Seismic Simulation Data Ji Liu Zenith Postdoc Wednesday 6 December at 11h Room: 02/124, Bat 5 Abstract: In recent years, big  simulation data is commonly generated from specific models,  in  different applications domains (astronomy, bioinformatics social networks, etc). In general, the simulation data corresponds to meshes that represent for …
