An application for gait recognition using persistent homology [Artículo]
(Universidad de Sevilla, 2013)
This Demo presents an application for gait recognition using persistent homology. Using a background subtraction approach, a silhouette sequence is obtained from a camera in a controlled environment. A border simplicial ...
Characterizing Configurations of critical points through LBP Extended Abstract [Artículo]
(Universidad de Sevilla, 2015)
In this abstract we extend ideas and results submitted to [3] in which a new codification of Local Binary Patterns (LBP) is given using combinatorial maps and a method for obtaining a representative LBP image is developed ...
The resolving number of a graph [Artículo]
(2013)
We study a graph parameter related to resolving sets and metric dimension, namely the resolving number, introduced by Chartrand, Poisson and Zhang. First, we establish an important difference between the two parameters: ...
The determining number of Kneser graphs [Artículo]
(2013)
A set of vertices S is a determining set of a graph G if every automorphism of G is uniquely determined by its action on S. The determining number of G is the minimum cardinality of a determining set of G. This paper studies ...
Sediment transport models in Shallow Water equations and numerical approach by high order finite volume methods. [Artículo]
(Elsevier, 2008)
This paper is concerned with the numerical approximation of bedload sediment transport due to water evolution. For the hydrodynamical component we consider Shallow Water equations. The morphodynamical component is defined ...
Efficient numerical schemes for viscoplastic avalanches. Part 1: The 1D case. [Artículo]
(Elsevier, 2014)
This paper deals with the numerical resolution of a shallow water viscoplastic flow model. Viscoplastic materials are characterized by the existence of a yield stress: below a certain critical threshold in the imposed ...
A multilayer method for the hydrostatic Navier-Stokes equations: a particular weak solution [Artículo]
(Ed. Plenum Press, 2014)
In this work we present a mutilayer approach to the solution of non-stationnary 3D Navier-Stokes equations. We use piecewise smooth weak solutions. We approximate the velocity by a piecewise constant (in z) horizontal ...
An energetically consistent viscous sedimentation model [Artículo]
(World Scientific Publishing, 2009)
In this paper we consider a two dimensional viscous sedimentation model which is a viscous Shallow-Water system coupled with a di usive equation that describes the evolution of the bottom. For this model, we prove the ...
Classification of filiform Lie algebras up to dimension 7 over finite fields [Artículo]
(Ovidius University, 2016)
This paper tries to develop a recent research which consists in using Discrete Mathematics as a tool in the study of the problem of the classification of Lie algebras in general, dealing in this case with filiform Lie ...
Análisis de algunas WebQuest dedicadas a la Historia de las Matemáticas [Artículo]
(Sociedad Canaria Isaac Newton de Profesores de Matemáticas, 2010-03)
Este artículo trata el concepto y la utilización de las WebQuest por parte del profesorado de Matemáticas en los diferentes niveles educativos, haciendo énfasis tanto en Educación Secundaria Obligatoria como en Bachillerato. ...
