Coding of biosignals using the discrete wavelet decomposition
(Springer, 2009)
Text en actes de congrés
Accés restringit per política de l'editorialWavelet derived codification techniques are widespread used in image codifiers. The wavelet based compression methods are adequate for representing transients. In this paper we explore the use of the discrete wavelet transform ... -
Data compression of natural signals based on discrete wavelet transform analysis
(2009)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper we explore the use of the discrete wavelet transform analysis of an arbitrary signal in order to improve the data compression capability of data coders. Wavelet analysis is widespread used in image codifiers, ... -
Extraction of vibration parameters from optical feedback interferometry signals using wavelets
(2015-12-01)
Article
Accés obertThis paper proposes the use of the wavelet transform as a technique that is suited for fringe detection and analysis of optical feedback interferometry (OFI) signals, thus allowing the retrieval of extremely small physical ... -
Finite element approximation of wave problems with correcting terms based on training artificial neural networks with fine solutions
(2022-09)
Article
Accés restringit per política de l'editorialIn this paper we present a general idea to correct coarse models by introducing a correcting term designed from fine solutions that can be then applied to situations in which a fine solution is not available. We apply this ... -
On some time marching schemes for the stabilized finite element approximation of the mixed wave equation
(2015-11)
Article
Accés obertIn this paper we analyze time marching schemes for the wave equation in mixed form. The problem is discretized in space using stabilized finite elements. On the one hand, stability and convergence analyses of the fully ...
