Sucre4Stem: Internet of things in classrooms
(IEEE, 2022)
We demonstrate Sucre4Stem, a training and
informative resource for promoting computational thinking
aimed at pre-university students, including visual programming
through blocks, assembly of sensors and actuators ...
Applying splitting methods with complex coefficients to the numerical integration of unitary problems
(American Institute of Mathematical Sciences (AIMS), 2022)
We explore the applicability of splitting methods involving complex coefficients to solve numerically the time-dependent Schr¨odinger equation.
We prove that a particular class of integrators are conjugate to unitary ...
Fast Kernel Smoothing of Point Patterns on a Large Network using Two-dimensional Convolution
(Wiley, 2019-06)
We propose a computationally efficient and statistically principled method for kernel smoothingof point pattern data on a linear network. The point locations, and the network itself, are convolvedwith a two-dimensional ...
On the computation of Darboux first integrals of a class of planar polynomial vector fields
(Elsevier, 2019-05)
We study the class of planar polynomial vector fields admitting Darboux first integrals of the type I I r i=1 fiαi , where the αi 's are positive real numbers and the fi 's are polynomials defining curves with only one ...
Constructive approximation of level continuous fuzzy functions 1
(IOS, 2019-06)
We consider the space of continuous functions defined between a locally compact Hausdorff space and the space of fuzzy numbers endowed with the level convergence topology. We obtain a Stone-Weierstrass type theorem for ...
Norm-attaining operators which satisfy a Bollobás type theorem
(Springer, 2021-04)
In this paper, we are interested in studying the set A(parallel to center dot parallel to) (X, Y) of all norm-attaining operators T from X into Y satisfying the following: given epsilon > 0, there exists eta such that if ...
Compositions of pseudo-symmetric integrators with complex coefficients for the numerical integration of differential equations
(Elsevier, 2020-05-29)
In this paper, we are concerned with the construction and analysis of a new class of methods obtained as double jump compositions with complex coefficients and projection on the real
axis. It is shown in particular that ...
On the number of invariant Sylow subgroups under coprime action
(Elsevier, 2017-07)
Let A and G be finite groups such that A acts coprimely on G via automorphisms. We study the number of A-invariant Sylow p-subgroups of G, say V a/p (G), for every prime p, and establish several arithmetical properties and ...
Combining Classification and User-Based Collaborative Filtering for Matching Footwear Size
(MDPI, 2021)
Size mismatch is a serious problem in online footwear purchase because size mismatch
implies an almost sure return. Not only foot measurements are important in selecting a size, but also
user preference. This is the ...
A Data Science Analysis of Academic Staff Workload Profiles in Spanish Universities: Gender Gap Laid Bare
(MDPI, 2021-06-25)
This paper presents a snapshot of the distribution of time that Spanish academic staff spend on different tasks. We carry out a statistical exploratory study by analyzing the responses provided in a survey of 703 Spanish ...
