      In this work we review the definition and basic properties of the different types of fuzzy sets that have appeared up to now in the literature. We also analyze the relationships between them and enumerate some of the ...
    • Interval type-2 fuzzy sets are generalization of interval-valued fuzzy sets: towards a wider view on their relationship 

      Bustince Sola, Humberto Upna; Fernández Fernández, Francisco Javier Upna; Hagras, Hani; Herrera, Francisco; Pagola Barrio, Miguel Upna; Barrenechea Tartas, Edurne Upna (IEEE, 2015)   Artículo / Artikulua  OpenAccess
      In this paper, we will present a wider view on the relationship between interval-valued fuzzy sets and interval type- 2 fuzzy sets where we will show that interval-valued fuzzy sets are a particular case of the interval ...
    • Quantifying repressive acts: explanation and challenges of the documentary archive of historical memory in Navarre 

      Majuelo Gil, Emilio Upna; Mendiola Gonzalo, Fernando Upna; Garmendia Amutxastegi, Gotzon; Piérola Narvarte, Gemma Upna; García Funes, Juan Carlos Upna; Yániz Berrio, Edurne; Pérez Ibarrola, Nerea Upna; Barrenechea Tartas, Edurne Upna; Rodríguez Martínez, Iosu; Sesma Redín, Rubén; Bustince Sola, Humberto Upna (2019)   Documento de trabajo / Lan gaia  OpenAccess
