Research report
Open AccessIn this article, motivated by the study of symplectic structures on manifolds with bound-ary and the systematic study ofb-symplectic manifolds started in [10], we prove a slice theorem forLie group actions onb-symplectic manifolds -
A bioinspired methodology based on an artificial immune system for damage detection in structural health monitoring
(2015-01-01)
Article
Open AccessAmong all the aspects that are linked to a structural health monitoring (SHM) system, algorithms, strategies, or methods for damage detection are currently playing an important role in improving the operational reliability ... -
A black-box model for neurons
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessWe explore the identification of neuronal voltage traces by artificial neural networks based on wavelets (Wavenet). More precisely, we apply a modification in the representation of dynamical systems by Wavenet which decreases ... -
A blended learning/teaching methodology case study in the context of the EngiMath@UPC+ innovation project
(International Association of Technology, Education and Development (IATED), 2024)
Conference lecture
Open AccessThe EngiMath@UPC+ project consists of a proposal to introduce an online training material, the main output of the European ERASMUS+ EngiMath project, as a blended learning methodology in a wide range of Linear Algebra ... -
A boundary control technique to the string-tip-mass system based on a non-symmetric peak-detector model
(2017)
Conference report
Restricted access - publisher's policyThis paper presents a vibration control design to the string-tip-mass system by using a non-symmetric peakdetector mechanism. Previously, this peak-detector system was used as an easy algorithm to mitigate vibration on ... -
A brief introduction to synthetic differential geometry
(Universitat Politècnica de Catalunya, 2017-09)
Bachelor thesis
Open AccessThe goal of this thesis is to explore the basic axiomatic theory of Syn- thetic Differential Geometry (SDG). This field aims to put the study of smooth manifolds, and geometry therein, in a topos-theoretic framework. Though ... -
A BRILS metaheuristic for non-smooth flow-shop problems with failure-risk costs
(2016-02-01)
Article
Open AccessThis paper analyzes a realistic variant of the Permutation Flow-Shop Problem (PFSP) by considering a non-smooth objective function that takes into account not only the traditional makespan cost but also failure-risk costs ... -
A Caginalp phase-field system based on type III heat conduction with two temperatures
(2016-06-01)
Article
Open AccessOur aim in this paper is to study a generalization of the Caginalp phasefield system based on the theory of type III thermomechanics with two temperatures for the heat conduction. In particular, we obtain well-posedness ... -

A Categorical approach to Tannaka Duality
(Universitat Politècnica de Catalunya, 2016-07)
Master thesis
Open AccessThe aim of this work is to study, in a categorical context, similar results to the Tannaka-Krein duality theorem. We prove a reconstruction theorem which allows one to recover a given group G as the monoid of natural ... -
A Central Limit Theorem for inner functions
(2022-06)
Article
Open AccessA Central Limit Theorem for linear combinations of iterates of an inner function is proved. The main technical tool is Aleksandrov Disintegration Theorem for Aleksandrov-Clark measures. -
A chaotic secure communication system design based on iterative learning control theory
(Multidisciplinary Digital Publishing Institute, 2016-10-01)
Article
Open AccessThis paper presents an application of Iterative Learning Control (ILC) theory to secure communication system design by using chaotic signals, where the logistic-map is employed as a source of chaos. Meanwhile, the ILC ... -
A characterization of weighted simple games based on pseudoweightings
(2020-09-14)
Article
Open AccessThe paper provides a new characterization of weighted games within the class of simple games. It is based on a stronger form of the point-set-additive pseudoweighting property of simple games. The characterization obtained ... -
A classroom activity to work with real data and diverse strategies in order to build diverse models with the help of the computer
(2015)
Article
Open AccessTaking into account that the majority of the models with more tradition in the mathematical curriculum to represent temporal evolutions of the number of individuals are continuous models in the class of empirical models, ... -
