Numerical studies of aerofractures in porous media / Estudios numericos de aerofractures en medios porosos [PDF]
Revista Cubana de Fisica 29, 1E (2012) 66, 2012 During the hydraulically induced compaction of a granular layer fracture patterns arise. In numerical simulations we study how these patterns depend on the gas properties as well as on the properties of the porous medium. In particular the relation between the speed of fracture propagation and injection pressure is here studied in detail.

Cartografica e Geografia, a cura di Riccardo Morri e Cristiano Pesaresi,
Universita' degli Studi di Roma La Sapienza, 2007 vol. 2, p. 151-164 (2007), 2012 The observation of a central eclipse from the umbral band and, even better, from its edge allows to measure the solar diameter with an accuracy up to a part over 100000. The data of the annular eclipse of 22 september 2006 observed from Kourou, French Guyane and their calibration are presented.

Scout-It: Interior tomography using modified scout acquisition [PDF]
arXiv, 2016 Global scout views have been previously used to reduce interior reconstruction artifacts in high-resolution micro-CT and C-arm systems. However these methods cannot be directly used in the all-important domain of clinical CT. This is because when the CT scan is truncated, the scout views are also truncated.
