Quick regional centroid moment tensor solutions for the Emilia 2012 (northern Italy) seismic sequence
Earthquake source Seismic moment tensor Wave analysis Data processing
2015/8/26
In May 2012, a seismic sequence struck the Emilia region (northern Italy). The mainshock, of Ml 5.9, occurred on May 20, 2012, at 02:03 UTC. This was preceded by a smaller Ml 4.1 foreshock some hours ...
Astrometric Image Centroid Displacements due to Gravitational Microlensing by the Ellis Wormhole
Astrometric Image Centroid Displacements due to Gravitational Microlensing by the Ellis Wormhole
2011/10/17
Continuing work initiated in an earlier publication (Abe, ApJ, 725 (2010) 787), we study the gravitational microlensing effects of the Ellis wormhole in the weak-field limit. First, we find a suitable...

Abstract: We show that the rate of convergence on the approximation of volumes of a convex symmetric polytope P in R^n by its dual L_{p$-centroid bodies is independent of the geometry of P. In particu...
A centroid-based performance evaluation using aggregated fuzzy numbers
Aggregated fuzzy numbers centroid index
