Microscopic shape from focus using white light interferometric fringes
(OSA - The Optical Society, 2018)
In this work we study the use of a focus measure to improve the 3D reconstruction of low reflectivity microscopic samples using white light interference microscopy. Simulation and experimental results show the improved ...
Adaptive filtering of interference fringes by polar transformation and empirical mode decomposition
(OSA - The Optical Society, 2018)
We designed an adaptive filter based on empirical mode decomposition for the removal of fringes in an interference microscopy image. Promising results show the possibility for extended depth-of-field imaging. © 2018 The Author (s)
Numerical Simulations of a Polydisperse Sedimentation Model by Using Spectral WENO Method with Adaptive Multiresolution
(World Scientific Publishing Co. Pte Ltd, 2016)
In this work, we apply adaptive multiresolution (Harten's approach) characteristic-wise fifth-order Weighted Essentially Non-Oscillatory (WENO) for computing the numerical solution of a polydisperse sedimentation model, ...
A generalization of the Gauss–Bonnet–Hopf–Poincaré formula for sections and branched sections of bundles
(Elsevier B.V., 2017)
For a two-dimensional compact oriented Riemannian manifold (M,g), and a vector field V on M, the Hopf–Poincaré theorem combined with the Gauss–Bonnet theorem gives the Gauss–Bonnet–Hopf–Poincaré (GBHP) formula: ∑z∈Z(V)indz(V)= ...
Topological Invariants of Principal G-Bundles with Singularities
(Pleiades Publishing, 2018)
principal G-bundle with singularities is a principal bundle π: P¯ → M with structure group G¯ which reduces to a subgroup G ⊂ G¯ on the set M \ Σ, where M is an n-dimensional compact manifold and Σ ⊂ M is a k-dimensional ...
3-webs with singularities
(Maik Nauka-Interperiodica Publishing, 2016)
A 3-web with singularities is an ordered collection of three one-dimensional distributions L1, L2, L3 on a 2-dimensional manifold M. The subset Σ ⊂ M where these distributions are not pairwise transversal is called the ...
Design of an electrogoniometer based on accelerometers for the evaluation of sports gesture in weight lifting
(Institute of Electrical and Electronics Engineers Inc., 2014)
This article describes the design and implementation of an electrogoniometer to measure joint angles during the execution of weight lifting exercises. The electrogoniometer consists of four microelectromechanical accelerometers ...
Multi-server approach for high-throughput molecular descriptors calculation based on multi-linear algebraic maps
(Wiley-VCH Verlag, 2015)
The present report introduces a novel module of the QuBiLS-MIDAS software for the distributed computation of the 3D Multi-Linear algebraic molecular indices. The main motivation for developing this module is to deal with ...
Toward an automatic 3D measurement of skin wheals from skin prick tests
(SPIE, 2019)
The skin prick test (SPT) is the standard method for the diagnosis of allergies. It consists in placing an array of allergen drops on the skin of a patient, typically the volar forearm, and pricking them with a lancet to ...
Proposal of a theoretical model of branding for the positioning of the university brand
(Revista Espacios, 2017)
This article of reflection presents a vision of marketing potential and the applicability of one of its tools, called branding. In this is a historical review of branding, showing its importance through the times and how ...
