Discrete observations of the spatial distributions of the Helix aspersa snail in an outdoor system
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2009)
The use of discrete Markov random fields in reservoir characterization
(Elsevier Science BvAmsterdamHolanda, 2001)
Polarization instability, steering, and switching of discrete vector solitons
(2005)
We study the dynamics of discrete vector solitons in arrays of weakly coupled birefringent optical waveguides with cubic nonlinear response. We start with a modulational instability analysis, followed by approximate ...
Persistent homology for time series and spatial data clustering
(Pergamon/ElsevierOxford, 2015-09)
Topology is the branch of mathematics that studies how objects relate to one another for their qualitative structural properties, such as connectivity and shape. In this paper, we present an approach for data clustering ...
Assessment of multifractal analysis in dynamic laser speckle signals using a spatial light modulator
(Optical Society of America, 2019-02)
We assess and discuss several technical aspects of the multifractal statistical analysis applied to time series of dynamic speckle intensity signals. Due to the complexity of this goal, we implemented an optical setup that ...
Spatial dependencies during multi-criteria analysis for groundwater resource management at a local scale
(Elsevier Science, 2021-08)
The growth of emerging and intermediate cities in Latin America and the Caribbean has been one of the main causes of the gaps found in the access to water quality and sanitation services; therefore, there is a pressing ...
Mixed-state Markov models in image motion analysis
(Springer Verlag Berlín, 2011)
When analyzing motion observations extracted from image sequences one notes that the histogram of the velocity magnitude at each pixel shows a large probability mass at zero velocity, while the rest of the motion values ...
