A preliminary model for optimal load distribution in heterogeneous smart environments
(2019)
Conference report
Restricted access - publisher's policySmart cities are becoming popular and, with them, a plethora of resources is emerging turning into a massive concentration of computing devices. In such environments, the deployment of a smart resources management system ... -
Convexity for Hamiltonian torus actions on b-symplectic manifolds
(2014-12)
External research report
Open AccessIn [GMPS] we proved that the moment map image of a b-symplectic toric manifold is a convex b-polytope. In this paper we obtain convexity results for the more general case of non-toric hamiltonian torus actions on b-symplectic ... -
Coincidences between press releases and economic briefs: Quantitative and qualitative analysis of two Spanish newspapers La coincidencia entre las notas de prensa y los breves de economía: Análisis cuantitativo y cualitativo de dos periódicos españoles La coincidència entre les notes de premsa i els breus d'economia: Anàlisi quantitativa i qualitativa de dos diaris espanyols
(2018-01-01)
Article
Open AccessThe objective of this research is to compare the press releases of companies and public organizations and the briefs published by the media. With this goal in mind, it is intended to detect if the press release is processed ... -
Stable s-minimal cones in R 3 are flat for s ~ 1
(2019-01-01)
Article
Restricted access - publisher's policyWe prove that half spaces are the only stable nonlocal s-minimal cones in R3, for s¿(0,1) sufficiently close to 1. This is the first classification result of stable s-minimal cones in dimension higher than two. Its proof ... -
Harmonic distance in intervals and chords
(2019-05-01)
Article
Restricted access - publisher's policyThe harmonic distance between two pure tones, in the sense used by Tenney, is generalised to chords whose pitches are harmonic fractions. In the tonal graph generated by the harmonics involved in a chord, which for n-TET ... -
Do we really need cloud? Estimating the fog computing capacities in the city of Barcelona
(2018)
Conference report
Restricted access - publisher's policyFog computing has emerged as a novel and challenging technology intended to complement the features of the cloud computing paradigm by exploiting the opportunities of locality. Moving some computation to the edge of the ... -
Characterizing identifying codes from the spectrum of a graph or digraph
(Elsevier, 2019-06-01)
Article
Restricted access - publisher's policyA -identifying code in digraph D is a dominating subset C of vertices of D, such that all distinct subsets of vertices of D with cardinality at most l have distinct closed in-neighborhoods within C. As far as we know, it ... -
Exponentially small splitting of separatrices associated to 3D whiskered tori with cubic frequencies
(2019-06)
External research report
Open AccessWe study the splitting of invariant manifolds of whiskered (hyperbolic) tori with three frequencies in a nearly-integrable Hamiltonian system, whose hyperbolic part is given by a pendulum. We consider a 3-dimensional ... -
On simultaneously and approximately simultaneously diagonalizable m-tuples of matrices
(Fundamental Journal of Mathematics and Applications, 2019)
Article
Open AccessIn this paper, the problem of simultaneous diagonalization of m-tuples of n-order square complex matrices, is analyzed and some necessary and some necessary and sufficient conditions for this property to be fulfilled are ... -

The GNSS Laboratory Tool Suite (gLAB) updates: SBAS, DGNSS and Global Monitoring System
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Restricted access - publisher's policyThis work presents recent and ongoing updates to the free and open-source advanced interactive multi-purpose package for processing and analysing Global Navigation Satellite System (GNSS) data, named GNSS-Lab Tool suite ... -
Acyclic edge colourings of graphs with large girth
(2016-11-03)
Article
Open AccessAn edge colouring of a graph G is called acyclic if it is proper and every cycle contains at least three colours. We show that for every e > 0, there exists a g = g(e) such that if G has maximum degree ¿ and girth at least ...
