Unsupervised classification of children’s bodies using currents
(Springer Verlag, 2018-06)
Object classification according to their shape and size is of key importance in many scientific fields. This work focuses on the case where the size and shape of an object is characterized by a current. A current is a ...
Stability of King’s family of iterative methods with memory
(Elsevier, 2017-07)
In the literature exist many iterative methods with memory for solving nonlinear equations, the most of them designed in the last years. As they use the information of (at least) the two previous iterates to generate the ...
Existence of normal Hall subgroups by means of orders of products
(Wiley-VCH Verlag, 2018)
Let G be a finite group, let π be a set of primes and let p be a prime. We characterize the existence of a normal Hall π‐subgroup in G in terms of the order of products of certain elements of G. This theorem generalizes a ...
Isometries on spaces of absolutely continuous functions in a noncompact framework
(Elsevier, 2020-02-19)
In this paper we deal with surjective linear isometries between spaces of scalar-valued absolutely continuous functions on arbitrary (not necessarily closed or bounded) subsets of the real line (with at least two points). ...
Lebesgue regularity for differential difference equations with fractional damping
(Wiley, 2018)
We provide necessary and sufficient conditions for the existence and unique-ness of solutions belonging to the vector-valued space of sequences �(Z, X) forequations that can be modeled in the formΔu(n)+Δu(n)=Au(n)+G(u)(n)+ ...

Nonparametric tilted density function estimation: A cross-validation criterion
(Elsevier, 2018-12)
In this paper, we propose a tilted estimator for nonparametric estimation of a density function. We use a cross-validation criterion to choose both the bandwidth and the tilted estimator parameters. We demonstrate theoretically ...
A neuroimaging data set on problem solving in the case of the reversal error: Putamen data
(Elsevier, 2020-09-19)
Structural Magnetic Resonance Images (sMRI) for a sample of university students were recorded. Out of magnetic resonance, students performed a test of algebra problem solving. As we are interested in reversal errors, the ...
Detection of Anomalies in Water Networks by Functional Data Analysis
(Hindawi Publishing Corporation, 2018)
A functional data analysis (FDA) based methodology for detecting anomalous flows in urban water networks is introduced. Primary hydraulic variables are recorded in real-time by telecontrol systems, so they are functional ...
