Las facerías en el Pirineo navarro: una perspectiva historico-económica
Las facerías aparecen como acuerdos entre municipios vecinos para regular la explotación común de algunos recursos, especialmente de hierbas y aguas o para institucionalizar la resolución de conflictos en ese terreno. ... -
Las facerías internacionales en el Pirineo: historia, actualidad y futuro
(Sociedad Española para el Estudio de los Pastos, 2012) Contribución a congreso / Biltzarrerako ekarpenaLa ponencia define el concepto de facería internacional pirenaica y realiza en sus primeros apartados una síntesis histórica de sus orígenes y de su evolución a lo largo de sus ocho siglos de existencia. Se realiza ... -
A fast SSVEP-based brain-computer interface
Literature of brain-computer interfacing (BCI) for steady-state visual evoked potentials (SSVEP) shows that canonical correlation analysis (CCA) is the most used method to extract features. However, it is known that CCA ... -
Femtosecond laser inscription of diffraction gratings in CYTOP fibers for optical fiber sensing
The use of the new CYTOP fibers for the inscription of optical structures and the sensing of different parameters has started to gain importance in the last decade. This work presents the design and manufacture of a CYTOP ... -
Fiber optic mirror fabrication using general-purpose metallic pigments
In this work, the potential of using general-purpose paints to fabricate highly reflective, low-cost optical mirrors is evaluated. The study shows that high-reflectivity mirrors can be created in standard single-mode fiber ... -
Fiber optic sensor based on fluorescence quenching for heavy metal detection
In this paper, we present the preliminary results of a fiber optic sensor based on fluorescence quenching induced by mercury (Hg) concentrations presence in aqueous solutions. The fabrication of the sensor head consists ... -
Fiber-based label-free D-dimer detection for early diagnosis of venous thromboembolism
D-dimer is a useful diagnostic biomarker for deep vein thrombosis or pulmonary embolism, collectively referred to as venous thromboembolism (VTE). The ability to detect in real-time the amount of D-dimer with a fast and ... -
Fiber-optic immunosensor based on lossy mode resonances induced by indium tin oxide thin-films
A novel immunosensor based on lossy mode resonances (LMRs) induced in optical fibers is developed in this contribution. Indium tin oxide (ITO) is sputtered on the optical substrate to generate an LMR in the transmission ... -
Fiber-optic lossy mode resonance sensors
In the last 4 years, experimental evidences about the potential use of optical sensors based on Lossy Mode Resonances (LMR) have been presented in the literature. These LMR sensors have some similarities with Surface ... -
Filtro paso banda en tecnología groove gap waveguide con altura de pines reducida para facilitar su fabricación
In this work, a novel topology of groove gap waveguide (GGW) technology is presented to facilitate the fabrication process by Computer Numerical Control (CNC) milling. GGW has been proposed as an interesting alternative ... -
Fire in the woods or fire in the boiler: implementing rural district heating to reduce wildfire risks in the forest-urban interface
Many rural communities in British Columbia (western Canada) are at risk from wildfire. This risk will increase over time as a result of climate change because of higher average temperatures, longer growing seasons, and ... -
A first study on the use of interval-valued fuzzy sets with genetic tuning for classification with imbalanced data sets
Classification with imbalanced data-sets is one of the recent challenging problems in Data Mining. In this framework, the class dis- tribution is not uniform and the separability between the classes is often difficult. ... -
La fiscalidad ambiental sobre el agua: experiencias autonómicas
(Instituto Sindical de Trabajo, Ambiente y Salud (ISTAS), 2007) Contribución a congreso / Biltzarrerako ekarpenaLa situación actual de la fiscalidad ambiental autonómica resulta notablemente insuficiente. En muchas comunidades no existe ningún tributo sobre el uso del agua, en ocho comunidades existen exclusivamente cánones de ... -
El fisco desde abajo: el impacto de las contribuciones directas sobre los patrimonios agrarios durante el siglo XIX
El objetivo de este trabajo es el de aportar una perspectiva poco usual sobre los sistemas fiscales del siglo XIX. La reconstrucción del impacto de la fiscalidad durante la etapa final del Antiguo Régimen y durante la ... -
Flat lens antenna using gap waveguide technology at millimeter waves
In this paper, a flat lens antenna using Gap Waveguide (GW) technology working in the millimeter waves band was designed. The metamaterial lens is fed using a Groove Gap Waveguide (GGW) horn antenna in order to achieve a ... -
Folded Cascode OTA with 5540 MHzpF/mA FoM
A micropower single-stage folded cascode amplifier able to drive a wide range of capacitive loads is presented. It features class AB operation and includes power-efficient adaptive biasing techniques, which provide enhanced ... -
A framework for active contour initialization with application to liver segmentation in MRI
Object segmentation is a prominent low-level task in image processing and computer vision. A technique of special relevance within segmentation algorithms is active contour modeling. An active contour is a closed contour ... -
