In this paper, we investigate the importance of the high frequencies in the problem of convolutive blind source separation (BSS) of speech signals. In particular, we focus on frequency domain blind source separation (FD-BSS), and show that when separation is performed in the low frequency bins only, the recovered signals are similar in quality to those extracted when all frequencies are taken i...

traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. to design a membrane process for olefin-paraffin separation, equilibriu...

In this article we establish new inequalities, both conditional and unconditional, for the restriction problem associated to hyperbolic, or one-sheeted, hyperboloid in three dimensions, endowed with a Lorentz-invariant measure. These inequalities are unconditional (and optimal) bilinear range q>103. Nous obtenons des nouvelles inégalités pour le problème de la transformée Fourier associé à l'hy...

Highlighting how crustal shortening is accommodated in space and time fold-thrust belts a major issue for understanding the long-term tectonic evolution of orogenic systems. In this study, we combine surface subsurface data to build 150 km-long sequentially restored balanced cross-section across two superimposed foreland southeastern France: upper Cretaceous-Eocene Provençal belt Oligocene-Neog...

Abstract Whiteschists from the Monte Rosa Nappe were examined in field as well with petrographic, geochemical, and isotopic methods to constrain controversial origin of these rocks their Alpine metamorphic context. occur ellipsoidal-shaped, decametric-sized bodies, within a Permian metagranite, consist mainly chloritoid, talc, phengite, quartz. The transition whiteschist metagranite is marked b...

Dicussions 882 Despite the often divergent opinions regarding the evolution of the Teslin suture zone (TSZ), previous tectonic models broadly agree that the TSZ comprises a ductile shear zone that constitutes a fundamental crustal boundary (e.g., Tempelman-Kluit 1979; Erdmer 1985; Hansen 1989; Stevens and Erdmer 1996; Hansen and Dusel-Bacon 1998). In contrast, de Keijzer et al. (1999) offer a r...
