Evaluation of interest point detectors for image information extraction
(IOS PRESS, 2012-01-01)
Interest points extraction and matching is a common task in many computer vision based application, which are used in different domains, such as 3D reconstruction, object recognition, or tracking. We present an evaluation ...
Microscale investigations of highfrequency wave propagation through highly porous media
(WILEY-VCH Verlag, 2012-12-03)
Wave propagation in highly porous materials has a well established theoretical background -- Still there are parameters which require complex laboratory experimentation in order to find numerical values -- This paper ...
Finite element modeling of micropolar-based phononic crystals
(Elsevier BVUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2019-11-11)
The performance of a Cosserat/micropolar solid as a numerical vehicle to represent dispersive media is explored. The study is conducted using the finite element method with emphasis on Hermiticity, positive definiteness, ...
Digital material laboratory: Wave propagation effects in open-cell aluminium foams
(Elsevier, 2012-09)
This paper is concerned with numerical wave propagation effects in highly porous media using digitized images of aluminum foam -- Starting point is a virtual material laboratory approach -- The Aluminum foam microstructure ...
PL-Geodesics on PL-continuous partial meshes
(2001)
Geometric characteristics of 2-manifolds embedded in R3 space have been analyzed from the point of view of differential geometry and topology -- In the past, results relevant to these areas have been found for C∞ curves ...

Talbot and Lau phenomena implementation via a photorefractive converter
(SPIE, 1999-07-06)
We propose a novel implementation of the Lau and Talbot effects. It employs a grating registered as modulation of birefringence in a Bi12SiO20 crystal. The systems proposed allow to control the visibility and in particular ...

Experimental design as a tool for the manufacturing of filtering media based on electrospun polyacrylonitrile/-cyclodextrin fibers
(Springer-Verlag France, 2016-05-01)
The aim of this work is the manufacturing of non-woven fabrics to be used as Filtering media. These fabrics were produced from polyacrilonitrile (PAN) and -cyclodextrin (-CD) solutions in dimethylsulfoxide using a horizontal ...
