Updating digital twins: Methodology for data accuracy quality control using machine learning techniques
(Elsevier, 2023-10)
The Digital Twin (DT) constitutes an integration between cyber and physical spaces and has recently become a popular concept in smart manufacturing and Industry 4.0. The related literature provides a DT characterisation ...

Design of water quality policies based on proportionality in multi-issue problems with crossed claims
(Elsevier, 2023-12-01)
Water pollutants can be classified into three categories, each of which includes several classifications of substances. In this paper, we present a methodology based on bankruptcy models to determine the emission limits ...

Data Fault Detection for Digital Twin Learning Action Decision of a Wind Turbine
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2022)
This paper presents the design of a classifier of variable failures in a wind turbine system. The classifier is based on a structure formed by several TS fuzzy inference systems, with projections of the data onto ...

A new simple proof for Lum–Chua's conjecture
(Elsevier, 2021-05)
The already proved Lum–Chua’s conjecture says that a continuous planar piecewise linear differential system with two zones separated by a straight line has at most one limit cycle. In this paper, we provide a new proof by ...

Angular Extents and Trajectory Slopes in the Theory of Holomorphic Semigroups in the Unit Disk
(Springer, 2021-04)
We study relationships between the asymptotic behaviour of a non-elliptic semigroup of holomorphic self-maps of the unit disk and the geometry of its planar domain (the image of the Koenigs function). We establish a ...

Knapsack models applied to the solution of complex problems in transport planning
(2023-05-15)
This thesis has been developed during the competitive research projects aimed at promoting the use of mathematical optimization models for decision-making in complex contexts where there are often conflicting interests ...

A mixed integer linear programming model for resolution of the antenna-satellite scheduling problem
(Institute of Electrical and Electronics Engineers, 2024-02)
This article deals with one of the types of “Satellite Range Scheduling” problems arising in Earth Observation Satellite operations, Antenna-Satellite Scheduling. Given a set of satellites, a set of available antennas and ...

Mixed norm spaces and RM(p, q) spaces
(Springer, 2023)
In this paper we present the containment relationship between the spaces of analytic functions with average radial integrability RM(p, q) and a family of mixed norm spaces.

Uniform in Time Error Estimates for a Finite Element Method Applied to a Downscaling Data Assimilation Algorithm for the Navier--Stokes Equations
(Society for Industrial and Applied Mathematics Publications (SIAM), 2020)
In this paper we analyze a finite element method applied to a continuous downscal-ing data assimilation algorithm for the numerical approximation of the two- and three-dimensionalNavier–Stokes equations corresponding to ...

Double-zero degeneracy and heteroclinic cycles in a perturbation of the Lorenz system
(Elsevier, 2022-08)
In this paper we consider a 3D three-parameter unfolding close to the normal form of the triple-zero bifurcation exhibited by the Lorenz system. First we study analytically the double-zero degeneracy (a double-zero eigenvalue ...
