The simulation of radiation problems typically involves localized excitation of a small and refined portion of the mesh representing the antenna. Due to this fact and the implicit units imbalance of problems comprising wire and surface elements, the convergence of the iterative solutions often shows a bad behavior. In this work, a preconditioning scheme is presented which moderates the strong dominance...
In this paper, we demonstrate the usefulness of a variation of the single-level FMM, namely the FMM-Fast Fourier Transform (FMM-FFT), to take advantage of the large amount of computational resources available in modern HPC systems.
This paper focuses on automated content update for MHP applications. Some of the authors have been involved in the first MHP trials of TVG, the TV channel of Galicia, NW Spain (three million population). It has a 30% share at regional level, competing with national channels. However, the initial MHP trials have raised the problem of manual content update cost, since in many key applications, like...
