Stratigraphie du Dogger et crise lusitanienne dans la Serra de Candeeiros
Ruget, Ch.; Thierry, J.; Rocha, R. B.; Delance, J. H.; Laurin, B.; Mouterde, R.; Tintant, H.New elements about the stratigraphy of the Serra de Candeeiros Dogger and Lower «Lusitanian» are presented. The Lower Aalenian was recognized for the first time. Bathonian (more than 50 metres thick) is dated on brachiopods and foraminifera. It corresponds to a series of massive micritic, biodetritical, coral-reef, chaetetid, bryozoa and oolitic-limestones. Callovian (120 m) begins by whitish or yellowish limes...
Three-dimensional reconstruction of non-homogeneous dielectric objects by the c...
Bassrei,Amin; Lemaire,Thierry J.In this paper we present an inversion procedure for electromagnetic scattering, based on the coupled-dipole method (CDM) combined with an inversion algorithm making use of the singular value decomposition procedure associated with a regularization factor. This method permits to obtain images of non-homogeneous dielectric objects whose dimensions are comparable to the incident wavelength. The feasibility of this...
