        <dc:description xml:lang="en">Next generation networks will result from the convergence of the different existing technologies, taking benefit from their complementary properties . In this context, recent research has addressed Digital Video Broadcast (DVB) networks, which benefit of very high broadcast capacities, and has tried to couple them with complementary networks. In our work, we focus on DVB-SH, satellite services for hand-held devices, which is a hybrid (satellite/terrestrial) standard. We couple DVB-SH with a 3G cellular network, thus providing a bidirectional interactivity path. DVB-SH benefits from a very high bandwidth capacity that allows unidirectional IP-TV channels broadcast. A residual bandwidth in the DVB-SH path may still be available because of two reasons; the variable bit rates of served flows and/or some DVB reserved channels by the 3G provider. In our work, we focus on this small residual bandwidth and its potential utilization. The idea is to realize an efficient switching of IP data, coming from 3G networks, to the residual bandwidth of DVB Networks. The goal is to use this architecture in order to provide interactive low cost services over DVB networks.

Dans un second temps, elle met &#xE0; l'&#xE9;preuve de l'exp&#xE9;rience cette conception politique de la disparition, en prenant l'exemple des abolitions op&#xE9;r&#xE9;es pendant la p&#xE9;riode r&#xE9;volutionnaire.</dc:description>

        <dc:description xml:lang="en">A great number of image reconstruction algorithms, based on analytical filtered backprojection, are implemented for X-ray Computed Tomography (CT) [1, 3]. The limits of these methods appear when the number of projections is small, and/or not equidistributed around the object. In this specific context, iterative algebraic methods are implemented. A great number of them are mainly based on least square criterion. Recently, we proposed a regularized version based on Bayesian estimation approach. The main problem that appears when using such methods as well as any iterative algebraic methods is the computation time and especially for projection and backprojection steps. In this paper, first we show how we implemented some main steps of such algorithems which are the forward projection and backward backprojection steps on GPU hardware, and then we show some results on real application of the 3D tomographic reconstruction of metallic foams from a small number of projections. Through this application, we also show the good quality of results as well as a significant speed up of the computation with GPU implementation.</dc:description>
