      Photovoltaic module temperature is a detrimental parameter influencing the energy yield and the durability of photovoltaic systems. Among the passive strategies to reduce the operating temperature of solar cells, radiative ...
    • Erratum: “Transmission spectra changes produced by decreasing compactness of opal like structures” J. Appl. Phys. 105, 024910 (2009) 

      Andueza Unanua, Ángel María Upna Orcid; Echeverría, R.; Morales Zimmermann, Paola Andrea Upna; Sevilla Moróder, Joaquín Upna Orcid (AIP Publishing, 2011)   Otros / Bestelakoak  OpenAccess
      Performing a systematic review of our experimental data, we have realized that we introduced a significant mistake in our abovementioned publication. Figure 3 did not correspond to the situation described, and should be ...
    • Experimental development and testing of low-cost scalable radiative cooling materials for building applications 

      Carlosena Remírez, Laura Upna Orcid; Andueza Unanua, Ángel María Upna Orcid; Torres, Luis; Irulegi, Olatz; Hernández-Minguillón, Rufino J.; Sevilla Moróder, Joaquín Upna Orcid; Santamouris, Mattheos (Elsevier, 2021)   Artículo / Artikulua  OpenAccess
      Urban overheating has a serious impact on building energy consumption. Daytime radiative cooling materials are an interesting passive solution for refrigeration. However, their costs and complex manufacturing hinder their ...
    • Geometry influence on the transmission spectra of dielectric single layers of spheres with different compactness 

      Andueza Unanua, Ángel María Upna Orcid; Echeverría, R.; Morales Zimmermann, Paola Andrea Upna; Sevilla Moróder, Joaquín Upna Orcid (AIP Publishing, 2010)   Artículo / Artikulua  OpenAccess
      The transmission of spectra of different dielectric spheres single layer arrangements has been measured. High dielectric permittivity ε =7 spheres of several millimeters of diameter were used to build the samples whose ...
    • Gramática de las gráficas: pistas para mejorar las representaciones de datos 

      Sevilla Moróder, Joaquín Upna Orcid (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2005)   Libro / Liburua  OpenAccess
      Periodistas, científicos, sociólogos, ingenieros, economistas... En multitud de profesiones nos encontramos con la necesidad de interpretar o de realizar gráficas. Las gráficas son elementos habituales en multitud de ...
    • Growth in the number of references in engineering journal papers during the 1972-2013 period 

      Úcar Marqués, Iñaki; López Fernandino, Felipe; Rodríguez Ulibarri, Pablo Upna Orcid; Sesma Sánchez, Laura Upna; Urrea Micó, Verónica Upna; Sevilla Moróder, Joaquín Upna Orcid (Springer, 2014)   Artículo / Artikulua  OpenAccess
      The number of references per paper, perhaps the best single index of a journal’s scholarliness, has been studied in different disciplines and periods. In this paper we present a four decade study of eight engineering ...
