In this article we study the problem of signal recovery for group models. More precisely for a given set of groups, each containing a small subset of indices, and for given linear sketches of the true signal vector which is known to be group-sparse in the sense that its support is contai...
receiver array-filtered seismic data are investigated: (1) point receiver inversion where array effects are neglected; (2) preprocessing of the data with an inverse array filter, followed by point receiver inversion; (3) array inversion, where the array effects are included in the forward ...
(such as GIT) • Seismic/oil and gas • Media asset or HIPAA archives • File streaming workflows (such as video surveillance) • Unstructured NAS data (such as home directories) • Big data and data lakes (Hadoop with the NetApp NFS connector) • Virtualized workloads (ONTAP 9.8...
28 established the first numerical model to anticipate the seismic wave field generated by wind farms as well as simulate the complicated effects of wave field interferences, surface topography, and attenuation. This proposed modelling technique can accurately estimate the effects of several wind ...
Northern latitude and eastern longitude figures are reported in the frame; circles point at ENI/Agip wells (well names in italics). B) Simplified seismic section along the N-S trace in A) (redrawn after Pieri & Groppi 1981): Pg = Paleogene; Mi1-2 = Lower to Middle Miocene; Mi3 = ...
The angular unconformity at the base of the Grant Group forms a distinctive surface evident both at outcrop and in the subsurface on seismic and well logs. Detailed analysis of a 2D seismic dataset, integrated with available well data, suggests a complex suite of processes controlling the ...
