A q-extension of sigmoid functions and the application for enhancement of ultrasound images
(2019)
© 2019 by the authors.This paper proposes the q-sigmoid functions, which are variations of the sigmoid expressions and an analysis of their application to the process of enhancing regions of interest in digital images. ...
A priori-driven multivariate statistical approach to reduce dimensionality of MEG signals
(2013)
A magnetoencephalography (MEG) multivariate data exploratory analysis is described and implemented that combines the variance criterion used in principal component analysis with some prior knowledge about the sensory ...
A new ranking method for principal components analysis and its application to face image analysis
(2010)
In this work, we investigate a new ranking method for principal component analysis (PCA). Instead of sorting the principal components in decreasing order of the corresponding eigenvalues, we propose the idea of using the ...

An Overview of Microgrids Challenges in the Mining Industry
(2020)
The transition from fossil fuels to renewable energies as power sources in the heavy industries is one of the main climate change mitigation strategies. The carbon footprint in mining is related to its inherent extraction ...
Competitive content-based video copy detection using global descriptors
(2013)
Content-Based Video Copy Detection (CBVCD) consists of detecting
whether or not a video document is a copy of some known original and to retrieve
the original video. CBVCD systems rely on two different tasks: Feature ...
Austromegabalanus psittacus barnacle shell structure and proteoglycan localization and functionality
(Elsevier, 2015)
Comparative analyzes of biomineralization models have being crucial for the understanding of the functional properties of biominerals and the elucidation of the processes through which biomacromolecules control the synthesis ...
Epidemiology of chronic inflammatory demyelinating polyneuropathy in the South-Eastern area of Santiago, Chile
(Elsevier, 2020)
Chronic inflammatory demyelinating polyneuropathy (CIDP) is an immune-mediated polyneuropathy. It usually has an insidious onset, progressive course and heterogeneous clinical features. As far as we know, there is no ...
Synthesis and characterization of magnetite nanoparticles functionalized with organophosphorus compounds and its application as an adsorbent for La (III), Nd (III) and Pr (III) ions from aqueous solutions
(Elsevier B.V., 2019)
© 2018 In this communication, adsorbents based on functionalized magnetite nanoparticles were synthetized, characterized and evaluated as adsorbents for the uptake of La (III), Pr(III) and Nd(III) from aqueous solutions. ...
