Artículo / Artikulua
This paper is devoted to providing a unifying approach to the study of the uniqueness of unconditional bases, up to equivalence and permutation, of infinite direct sums of quasi-Banach spaces. Our new approach to this type ... -
Uniqueness of unconditional basis of ℓ2⊕T(2)
Albiac Alesanco, Fernando José ; Ansorena, José L. (American Mathematical Society, 2022)
Artículo / Artikulua
We provide a new extension of Pitt’s theorem for compact operators between quasi-Banach lattices which permits to describe unconditional bases of finite direct sums of Banach spaces X1 · · · Xn as direct sums of unconditional ... -
Unpaired spatio-temporal fusion of image patches (USTFIP) from cloud covered images
Goyena Baroja, Harkaitz; Pérez Goya, Unai ; Montesino San Martín, Manuel ; Militino, Ana F. ; Wang, Qunming; Atkinson, Peter M.; Ugarte Martínez, María Dolores (Elsevier, 2023)
Artículo / Artikulua
Spatio-temporal image fusion aims to increase the frequency and resolution of multispectral satellite sensor images in a cost-effective manner. However, practical constraints on input data requirements and computational ... -
Unsymmetrical basic uncertain information with some decision-making methods
Jin, LeSheng; Yager, Ronald R.; Chen, Zhen-Song; Mesiar, Radko; Bustince Sola, Humberto (IOS Press, 2022)
Artículo / Artikulua
Motivated by a specific decision-making situation, this work proposes the concept and definition of unsymmetrical basic uncertain information which is a further generalization of basic uncertain information and can model ... -
Use of Choquet integrals in multivalued contexts
Burusco Juandeaburre, Ana ; Alcalde, Cristina (Springer, 2020)
Artículo / Artikulua
In this work, multivalued contexts are studied, in which the different observations are related to each other. Continuing the studies already carried out in previous works, the use of Choquet integrals can be an adequate ... -
Using mortality to predict incidence for rare and lethal cancers in very small areas
Etxeberria Andueza, Jaione ; Goicoa Mangado, Tomás; Ugarte Martínez, María Dolores (VCH Publishers, 2022)
Artículo / Artikulua
Incidence and mortality figures are needed to get a comprehensive overview of cancer burden. In many countries, cancer mortality figures are routinely recorded by statistical offices, whereas incidence depends on regional ... -
Using publish/subscribe for message routing in mobile environments
(Springer, 2023) Artículo / Artikulua
Publish/subscribe is a mature communication paradigm to route and deliver events from publishers to interested subscribers. Initially conceived for large scale systems, e.g., the Internet, it has been used more recently ... -
