    Dense radar networks offer the possibility of getting better Quantitative Precipitation Estimates (QPE) than those obtained with individual radars, as they allow increasing the coverage and improving quality of rainfall ...
  • Scaling of 3D engine workloads on modern multi-GPU systems 

    Roca Sancho, Jordi; Grossman, Mark (Association for Computing Machinery (ACM), 2009)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This work supposes a first attempt to characterize the 3D game workload running on commodity multi-GPU systems. Depending on the rendering workload balance mode used, the intra and interframe dependencies due to ...
  • Tractament de la incertesa en estimació i previsió de pluja amb radars meteorològics
