In this talk, we discuss the issue of source separation in a signal on the sphere or on the plane, relying on the sparsity of one signal component in a scale-discretized steerable wavelet basis. The steerability of wavelets allows to probe in detail the lo ...
We present a unified framework for understanding the compaction of colloidal gels under their own weight. The dynamics of the collapse are determined by the value of the gravitational stress σg, as compared to the yield stress σY of the network. For σg
This paper discusses and optimizes an HMM/GMM based User-Customized Password Speaker Verification (UCP-SV) system. Unlike text-dependent speaker verification, in UCP-SV systems, customers can choose their own passwords with no lexical constraints. The pass ...
A specific choice of gauge is shown to imply a decoupling between the tensor and scalar components of gravitational radiation in the context of Brans–Dicke-type theories of gravitation. The comparison of the predictions of these theories with those of gene ...
We study the effect of a violation of the strong equivalence principle (SEP) on the cosmic microwave background (CMB). Such a violation would modify the weight of baryons in the primordial gravitational potentials and hence their impact in the establishmen ...

In this paper we examine the importance of fluid friction and nonlinearities due to the area-pressure relationship and to the convective acceleration on the separation of arterial pressure and flow waves into their forward and backward components. Experime ...
To determine self-consistently the time evolution of particle size and their number density in situ multi-angle polarization-sensitive laser light scattering was used. Cross-polarization intensities (incident and scattered light intensities with opposite p ...
A 40 kA Nb3Sn conductor, designed to operate with forced helium flow at 4.5 K was tested in the SULTAN III facility, (I(max) = 50kA, B(max) (background) = 11T). The test sample and the operating conditions of the test facility are described. Two measuremen ...
