      Vitoria Pascual, Ignacio Upna Orcid; Armas, Dayron; Coronel Camones, Carlos Manuel; Algarra González, Manuel; Ruiz Zamarreño, Carlos Upna Orcid; Matías Maestro, Ignacio Upna Orcid; Mukhopadhyay, Subhas C. (Springer, 2023)   Contribución a congreso / Biltzarrerako ekarpena
      A micro sized interdigital capacitor sensible to CO2 and NO is studied in this work. The photolithography technique enables to obtain fingers with dimensions of 10 × 500 µm and separated 7 µm between them. The deposition ...
    • Space-time parallel methods for evolutionary reaction-diffusion problems 

      Arrarás Ventura, Andrés Upna Orcid; Gaspar, F. J.; Portero Egea, Laura Upna Orcid; Rodrigo, C. (Springer, 2023)   Contribución a congreso / Biltzarrerako ekarpena
      In recent years, the gradual saturation of parallelization in space has been a strongmotivation for the design and analysis of new parallel-in-time algorithms. Amongthese methods, the parareal algorithm, first introduced ...
    • Grape stems as preservative in Tempranillo wine 

      Pires Nogueira, Danielle; Jiménez Moreno, Nerea Upna Orcid; Esparza Catalán, Irene Upna; Moler Cuiral, José Antonio Upna Orcid; Ancín Azpilicueta, Carmen Upna Orcid (2022)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      SO2 is the most widely used preservative in the wine industry. However, there are several drawbacks related with the use of SO2 in wine, such as, its toxicity and the unpleasant odor in case of excess [1]. These reasons ...
    • Smarterial – Smart matter optomagnetic 

      Irisarri Erviti, Josu; Galarreta Rodríguez, Itziar; Marzo Pérez, Asier Upna Orcid (2021)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Smart materials, also known as programmable materials, are a combination of different components that have the capability to change shape, move around and adapt to numerous situations by applying an external controllable ...
    • Hybrid xerogels doped with Tb(III) and Eu (III) and a water soluble Pybox ligand 

      Cruz Quesada, Guillermo Upna Orcid; Espinal Viguri, Maialen Upna Orcid; Garrido Segovia, Julián José Upna Orcid (2021)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Hybrid organic-inorganic siliceous materials (ORMOSiLs) are a key focus within the nanoscience area as they combine advantages of inorganic materials without losing characteristics intrinsic of organic molecules. In the ...
    • New hybrid organochlorinated xerogels 

      Cruz Quesada, Guillermo Upna Orcid; Espinal Viguri, Maialen Upna Orcid; López Ramón, María Victoria; Garrido Segovia, Julián José Upna Orcid (2021)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Hybrid silica xerogels (HSXG) combine the properties of organic and inorganic components in the same material, which makes them promising and versatile candidates for multiple applications. These materials can be easily ...
    • Bayesian modeling approach in Big Data contexts: an application in spatial epidemiology 

      Orozco Acosta, Erick Upna Orcid; Adin Urtasun, Aritz Upna Orcid; Ugarte Martínez, María Dolores Upna Orcid (IEEE, 2020)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this work we propose a novel scalable Bayesian modeling approach to smooth mortality risks borrowing information from neighbouring regions in high-dimensional spatial disease mapping contexts. The method is based on the ...
    • Why using topological and analytical methods in aggregation of fuzzy preferences? 

      Campión Arrastia, María Jesús Upna Orcid; Induráin Eraso, Esteban Upna Orcid; Raventós Pujol, Armajac Upna Orcid (2020)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The Arrow’s Impossibility Theorem states that there is no function fusing individual preferences into a social one satisfying certain properties of 'common sense'. On the contrary, in some of the fuzzy extensions of the ...
    • Study of the degradation of heat exchanger materials in the acidic environment of Teide National Park 

      Catalán Ros, Leyre Upna Orcid; Pérez Artieda, Miren Gurutze Upna Orcid; Berlanga Labari, Carlos Upna Orcid; Garacochea Sáenz, Amaia; Rodríguez García, Antonio Upna Orcid; Domínguez, Vidal; Montañez, Ana Carolina; Padilla, Germán D.; Pérez, Nemesio M. (2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Supplying power to volcanic monitoring stations constitutes a challenge due to both the access difficulties and the acidic environment associated with volcanoes. ELECTROVOLCAN project is developing thermoelectric generators ...
    • Interferometric vs wavelength selective optical fiber sensors for cryogenic temperature measurements 

      Miguel Soto, Verónica de Upna Orcid; Leandro González, Daniel Upna Orcid; López Aldaba, Aitor Upna; Beato López, Juan Jesús Upna Orcid; Pérez de Landazábal Berganzo, José Ignacio Upna Orcid; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe; López-Amo Sáinz, Manuel Upna Orcid (SPIE, 2017)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
