Humidity sensor based on a long-period fiber grating coated with a hydrophobic thin film
In this work it is proposed a novel fiber optic humidity sensor based on a functionally coated long-period fiber grating (LPG). The coating is composed of tetraorthosilicate matrix functionalized with perfluorooctyltriethoxysilane ... -
Hybrid xerogels doped with Tb(III) and Eu (III) and a water soluble Pybox ligand
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 ... -
Hydrogen educational activities developed by APERNA: a renewable-energy student association
In this paper, we present APERNA, a recently-created student association at Public University of Navarre (UPNA) with the aim of promotion of renewable energies. -
Hydrogen-lithium energy storage for a stand-alone microgrid
Sizing of the storage system for a stand-alone application: Satisfaction of technical requirements; Based on real data from an experimental microgrid; Long lifetime; Lowest price -
Hyperbolic lens antenna in groove gap waveguide technology at sub-millimeter waves
In this paper, a flat hyperbolic lens antenna using Groove Gap Waveguide (GGW) technology is designed at 300 GHz. A GGW horn antenna is used to feed the metamaterial lens placed in a parallel plate waveguide (PPW), in order ... -
Iconos y lugares: conflicto de representaciones naturales en el mundo rural
Se diferencian dos formas en la interpretación del espacio natural: una en tanto lugar y otra en tanto icono. El lugar natural es la interpretación de una comunidad humana con su entorno natural cercano, ha ido conformado ... -

La base de datos efectiva ha sido construida y elaborada a partir de la información proporcionada por ... -
Identification and functional characterisation of ctr1, a Pleurotus ostreatus gene coding for a copper transporter
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaCopper homeostasis is primordial for life maintenance and especially relevant for ligning-degrading fungi whose phenol-oxidase enzymes depend on this micronutrient for their activity. In this paper we report the ... -
Image feature extraction using OD-monotone functions
Edge detection is a basic technique used as a preliminary step for, e.g., object extraction and recognition in image processing. Many of the methods for edge detection can be fit in the breakdown structure by Bezdek, ... -
Image, brand and price info: do they always matter the same?
(Association for Computing Machinery (ACM), 2019) Contribución a congreso / Biltzarrerako ekarpenaWe study attention processes to brand, price and visual information about products in online retailing websites, simultaneously considering the effects of consumers’ goals, purchase category and consumers’ statements. We ... -
Imagen de Navarra y de los turistas que visitan la Comunidad Foral
(Gobierno de Navarra, Departamento de Economía y Hacienda, 2003) Contribución a congreso / Biltzarrerako ekarpenaEsta ponencia analiza la imagen que los visitantes de la Comunidad Foral tienen de ella, así como su percepción por los habitantes de Navarra. Para ello se han construido dos cuestionarios, uno para ser respondido por ... -
Imágenes hiperespectrales para el estudio de la respuesta a la deficiencia de nitrógeno de distintos cultivares de patata
(Sociedad Española de Ciencias Hortícolas, 2021) Contribución a congreso / Biltzarrerako ekarpenaEl cambio climático es uno de los mayores retos de la agricultura moderna. El aumento del rendimiento de los cultivos en el futuro sólo será posible si pueden hacer frente a las consecuencias del cambio climático causado ... -
Impedance modelling for high frequency unitraveling-carrier photodiodes
High-speed photodiodes stand out as potential candidates to enable next-generation communication systems working as mmWave/THz sources due to their intrinsic broadband behaviour. Impedance matching is an essential task in ... -
Implementacion de línea de ε negativa en tecnología stripline
In this work, a negative-ε equivalent response medium is proponed in stripline technology. To achieve band rejection behaviour, Complementary Split Ring Resonators (CSRR) are placed in the central conductor strip of ... -
