Décomposition d’Images Fondée sur l’Analyse de la Régularité Locale: Application au Codage Hybride d’Image
(2016-07-01)
La représentation hybride d'image utilise conjointement la décomposition en ondelettes pour l'information structurée et la modélisation paramétrique pour les textures. Dans ce cadre, nous proposons un algorithme qui décompose ...
Monte Carlo Simulation for Tomlinson Models for Non-Sinusoidal Periodic Potencials
(Springer/plenum Publishers, 2010-08)
It is shown that the velocity dependence of a tungsten tip sliding against a mica surface cannot be fit to a semi-empirical analytical solution of the Tomlinson/Prandtl model using a simple sinusoidal sliding potential. ...
Global considerations on the Kuramoto model of sinusoidally coupled oscillators
(2005)
In this article we study global stability properties of the Kuramoto model of sinusoidally coupled oscillators. We base our analysis on previous results by the con-trol community that analyze local properties of the consensus ...
On the nonlinear control of a single-phase current source converter for sinusoidal voltage generation
(Cartagena de Indias, 2020)
Colombian power system is being transformed for the large-scale integration of renewable energy resources and energy storage systems; all of these are integrated by power electronic converters controlled by voltage and ...
Load Characterization and Revenue Metering Under Non-Sinusoidal and Asymmetrical Operation
(Institute of Electrical and Electronics Engineers (IEEE), 2014-02-01)
This paper proposes an approach to load characterization and revenue metering, which accounts for the influence of supply deterioration and line impedance. It makes use of the Conservative Power Theory and aims at ...
Experimental poisoning by Senecio brasiliensis in calves: quantitative and semi-quantitative study on changes in the hepatic extracellular matrix and sinusoidal cells
(Colégio Brasileiro de Patologia Animal - CBPA, 2014)
Calling activity patterns in an anuran assemblage: the role of seasonal trends and weather determinants
(2008)
Calling activity of anuran assemblages were related to seasonal changes in weather factors such as temperature and rainfall. We evaluated the suitability of these variables as determinants of activity of an assemblage and ...
