Robust error bounds for the Navier-Stokes equations using implicit-explicit second-order BDF method with variable steps
(Oxford University Press / Institute of Mathematics and its Applications, 2023-09)
This paper studies fully discrete finite element approximations to the Navier–Stokes equations using inf-sup stable elements and grad-div stabilization. For the time integration, two implicit–explicit second-order backward ...

Optimisation of Maintenance Policies Based on Right-Censored Failure Data Using a Semi-Markovian Approach
(MDPI, 2022-02)
This paper exposes the existing problems for optimal industrial preventive maintenance intervals when decisions are made with right-censored data obtained from a network of sensors or other sources. A methodology based ...

Sobre el test de máxima potencia para hipótesis nula simple contra hipótesis alternativa simple.
(Sociedad de Estadística e Investigación Operativa, 1984)
El propósito de este trabajo es dar una construcción explícita del test de máxima potencia para un constraste de hipótesis paramétrico en el que tanto la hipótesis nual como la hipótesis alternativa son simples; utilizando ...

Saddle-node canard cycles in slow-fast planar piecewise linear differential systems
(Elsevier, 2024-05)
By applying a singular perturbation approach, canard explosions exhibited by a general family of singularly perturbed planar Piecewise Linear (PWL) differential systems are analyzed. The performed study involves both ...

Orbital Hypernormal Forms
(MDPI, 2021-08)
In this paper, we analyze the problem of determining orbital hypernormal forms—that is, the simplest analytical expression that can be obtained for a given autonomous system around an isolated equilibrium point through ...

A characterization of the Shapley value for cooperative games with fuzzy characteristic function
(Elsevier, 2020-11)
The characteristic function of a cooperative game determines the payment that each coalition can obtain when the players in the coalition cooperate. But there are cooperative situations in which the players have only ...

A novel methodology for public management of annual greenhouse gas emissions in the European Union
(Elsevier, 2023)
Global warming and climate change, as a result of greenhouse gas emissions, pose a major threat to the international community; therefore, such emissions must be reduced by moving to clean energy resources. In this paper, ...

Dieudonné-Köthe duality for vector-valued function spaces: localization of bounded sets and barrelledness
(National Inquiry Services Centre (NISC), 2010)
We study Dieudonné-Köthe spaces of Lusin-measurable functions with values in a locally convex space. Let Λ be a solid locally convex lattice of scalar-valued measurable functions defined on a measure space Ω. If E is a ...

Scaling and compressing melodies using geometric similarity measures
(Elsevier, 2022-08)
Melodic similarity measurement is of key importance in Music Information Retrieval. In this paper, we use geometric matching techniques to measure the similarity between two monophonic melodies. We propose efficient ...
