Detecting change-points in multivariate settings is usually carried out by analyzing all marginals either independently, via univariate methods, or jointly, through multivariate approaches. The former discards any inherent ... -
Asymptotic expansions for Moench's integral transform of hydrology
López García, José Luis ; Pagola Martínez, Pedro Jesús ; Pérez Sinusía, Ester (MDPI, 2023)
Artículo / Artikulua
Theis' theory (1935), later improved by Hantush & Jacob (1955) and Moench (1971), is a technique designed to study the water level in aquifers. The key formula in this theory is a certain integral transform H[g](r,t) of ... -

Artículo / Artikulua
Jam formation is a problem that may occur when granular material is discharged by gravity from a silo. The estimation of the minimum outlet size, which guarantees that the time to the next jamming event is long enough, can ... -
Some construction methods for pseudo-overlaps and pseudo-groupings and their application in group decision making
García-Zamora, Diego; Paiva, Rui; Cruz, Anderson; Fernández Fernández, Francisco Javier ; Bustince Sola, Humberto (MDPI, 2023)
Artículo / Artikulua
In many real-world scenarios, the importance of different factors may vary, making commutativity an unreasonable assumption for aggregation functions, such as overlaps or groupings. To address this issue, researchers have ... -
Democracy of quasi-greedy bases in p-Banach spaces with applications to the efficiency of the thresholding greedy algorithm in the hardy spaces Hp(Dd)
Albiac Alesanco, Fernando José ; Ansorena, José L.; Bello, Glenier (Cambridge University Press, 2023)
