Scalable video content adaptation
(Universidad Inca Garcilaso de la Vega, 2011-10)
Scalable Video Coding technology allows the efficient distribution of videos through heterogeneous networks. In this work a method for automatically adapting video contents, according to the available andwidth and user ...
MODELING THE UNVOICED COMPONENT IN THE CANONICAL REPRESENTATION OF SPEECH
(IEEE, 2009)
The canonical representation of speech constitutes a perfect reconstruction (PR) analysis-synthesis system. Its parameters are the autoregressive (AR) model coefficients, the pitch period and the voiced and unvoiced ...
Análise da escalabilidade de aplicações em computadores multicore
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC, 2013-06-14)
Multicore processors allow applications to explore thread-level parallelism in order to enable improvements on the elapsed time. The sharing of the memory subsystem and the discrepancy between the speeds of processors and ...
A hybrid MPI-OpenMP scheme for scalable parallel pseudospectral computations for fluid turbulence
(Elsevier Science, 2011-06)
A hybrid scheme that utilizes MPI for distributed memory parallelism and OpenMP for shared memory parallelism is presented. The work is motivated by the desire to achieve exceptionally high Reynolds numbers in pseudospectral ...
