Influence of zirconium addition on final properties of K0.5Na0.5NbO3-based ceramics
(Springer, 2013-11-08)
Microstructure, electrical and dielectric properties of K1/2Na1/2NbO3 (KNN) modified with ZrO2 were investigated. Powders were obtained by a conventional solid-state method. In this way, samples doped with 0.2 mol% of ZrO2 ...

Uniform consistency of kNN regressors for functional variables
(Elsevier, 2013-08)
This paper is devoted to nonparametric analysis of functional data. We give asymptotic results for a kNN generalized regression estimator when the observed variables take values in any abstract space. The main novelty is ...

Combination of HSV and RGB histograms and MPEG-7 Descriptor: Preliminar Results and Future Work
(2012-12)
In this paper we present the partial results obtained
with a new approach to combine HSV and RGB histograms
and MPEG-7 CLD descriptor. The combination
was conducted using Borda Voting-Schemes in three
databases: Wang, ...
An efficient algorithm for approximated self-similarity joins in metric spaces
(Elsevier, 2020)
Similarity join is a key operation in metric databases. It retrieves all pairs of elements that are similar. Solving such a problem usually requires comparing every pair of objects of the datasets, even when indexing and ...
