Comunicació de congrés
Accés restringit per política de l'editorial -
Multifractal observations of eddies, oil spills and natural slicks in the ocean surface
Platónov, Alexéi Konstantínovich; Carrillo Cortés, José Alejandro; Matulka, Anna Magdalena; Sekula, Emil; Grau Barceló, Joan; Redondo Apraiz, José Manuel; Tarquis, Ana Maria (2009-06-11)
Article
Accés restringit per política de l'editorialNatural and man-made distributions of tensioactive substance concentrations in the sea surface features exhibit self-similarity at all radar reflectivity levels when illuminated by SAR. This allows the investigation of the ... -
Multiscale analysis of SAR from the earth surface
Redondo Apraiz, José Manuel; Tarquis, Ana Maria; Matulka, Anna Magdalena; Platónov, Alexéi Konstantínovich (Universidad Complutense de Madrid (UCM), 2010)
Comunicació de congrés
Accés obertThe use of Synthetic Aperture Radar (SAR) to investigate the earth’s surface provides a wealth of useful information. Here we will discuss some recent fractal and multi-fractal techniques used to identify oil spills and ... -
Multiscaling properties on sequences of turbulent plumes images
Lopez Gonzalez-Nieto, Pilar; Tarquis Alfonso, Ana Maria; Matulka, Anna Magdalena; Skadden, Benjamin; Redondo Apraiz, José Manuel (2017-12-01)
Article
Accés obertA multifractal analysis on a finite-range-scale of the plume concentration images at different experimental conditions (the height of the source Ho), where the measure is the grey value of the image (from 0 to 255), was ... -
On the entrainment coefficient in a forced plume: quantitative effects of source parameter
Matulka, Anna Magdalena; Lopez Gonzalez-Nieto, Pilar; Redondo Apraiz, José Manuel; Tarquis Alfonso, Ana Maria (University of Thechnology and Agriculture Nicholas Copernicus University, 2014-02-24)
Article
Accés obertThe behavior of a forced plume is mainly controlled by the source buoyancy and momentum fluxes and the efficiency of turbulent mixing between the plume and the ambient fluid (stratified or not). The interaction between the ... -
ROFI structure in the gulf of Lions and the NW Mediterranean Sea: field and remote sensing observations of surface coherent structures
Fraunie, Philippe; Redondo Apraiz, José Manuel; Platónov, Alexéi Konstantínovich; Díez Rilova, Margarita; Matulka, Anna Magdalena (Universidad Complutense de Madrid (UCM), 2010)
Comunicació de congrés
Accés obertThe advances in radar sensors may be applied to study the flow in the region of fresh water influence (ROFI) region of the ocean. The Synthetic Aperture Radar (SAR) is a useful tool that may be used to study both marine ... -
Turbulent structure in environmental flows: effects of stratification and rotation
Matulka, Anna Magdalena (Universitat Politècnica de Catalunya, 2010-03-19)
Tesi
Accés obertSeveral series of experiments in stratified and in rotating/stratified decaying flows after a grid is used to stir the two layer stable fluid brine and fresh water set up. We measure by comparing the gained potential ... -
Vortex decay in stratified flows
Redondo Apraiz, José Manuel; Matulka, Anna Magdalena; Carrillo Cortés, José Alejandro (2010)
