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 ...
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 ...
Evaluation of a coupling interface for solving fluid-structure interaction problems
(Gauthier-Villars/Editions Elsevier, 2016-07)
This research work evaluates the performance of a Fluid-Structure Interaction (FSI) solver, which is created using a generic interface to couple two independent software packages. The basic idea is to combine the advantages ...
Video Conferencing Evaluation Considering Scalable Video Coding and SDN Network
(Instituto de Informática - Universidade Federal do Rio Grande do Sul, 2018)
A fast access big data approach for configurable and scalable object storage Enabling mixed fault-tolerance
(2017-07-01)
The progressive growth in the volume of digital data has become a technological challenge of great interest in the field of computer science. That comes because, with the spread of personal computers and networks worldwide, ...
Side-information generation for temporally and spatially scalablewyner-ziv codecs
(Hindawi Publishing Corporation, 2013)
Hybrid OpenMP/MPI programs for solving the time-dependent Gross–Pitaevskii equation in a fully anisotropic trap
(2016-03-01)
We present hybrid OpenMP/MPI (Open Multi-Processing/Message Passing Interface) parallelized versions of earlier published C programs (Vudragovic et al. 2012) for calculating both stationary and non-stationary solutions of ...
Practical compressed string dictionaries
(Elsevier, 2016)
The need to store and query a set of strings - a string dictionary - arises in many kinds of applications. While classically these string dictionaries have accounted for a small share of the total space budget (e.g., in ...
PetIGA: A framework for high-performance isogeometric analysis
(Elsevier Science Sa, 2016-08)
We present PetIGA, a code framework to approximate the solution of partial differential equations using isogeometric analysis. PetIGA can be used to assemble matrices and vectors which come from a Galerkin weak form, ...
