We propose a cell-centred symmetric scheme which combines the advantages of MPFA (multi point flux approximation) schemes such as the L or the O scheme and of hybrid schemes: it may be used on general non conforming meshes, it yields a 9-point stencil on two-dimensional quadrangular meshes, it takes into account the heterogeneous diffusion matrix, and it is coercive and convergent. The scheme r...

Bandwidth efficient modulation schemes using Reed-Solomon (RS) codes are proposed for Hybrid In-Band-On-Channel (IBOC) systems that broadcast digital audio signals simultaneously with analog Amplitude Modulation (AM) programs in the AM band. Since both the power and bandwidth allocated for digital audio transmission are limited in this application, the system cannot afford to add enough redunda...

We consider linear and nonlinear reaction-diffusion problems, and their time discretization by splitting methods. We give probabilistic interpretations of the splitting schemes, and show how these representations allow us to give error bounds for the deterministic propagator under weak hypothesis on the reaction part. To show these results, we only use the Itô formula, and basic properties of s...

Let {Si}i 1 be N strict pseudocontractions defined on a closed convex subset C of a real Hilbert space H. Consider the problem of finding a common element of the set of fixed point of these mappings and the set of solutions of an equilibrium problem with the parallel and cyclic algorithms. In this paper, we propose new iterative schemes for solving this problem and prove these schemes converge ...

This research develops a comparative study between different multiplicative weights that are assigned to the covariance matrix represents background error in two hybrid assimilation schemes: 3DEnVAR and 4DEnVAR. These distributed static time-invariant generated from perturbations of previous ensemble. The values 25%, 50%, 75%, always having as reference ensemble matrix. experiments applied shor...

A hybrid pulse interval modulation – code division multiple access (PIM-CDMA) is proposed. Expression for bit error rate (BER) is given. Numerical results presented are compared with hybrid PPM-CDMA and OOK-CDMA schemes. For a low number of users PIM-CDMA achieves similar and marginally lower BER performance compared with PPM-CDMA and OOK-CDMA, respectively. For large number users it offers bet...
