Bayesian modeling approach in Big Data contexts: an application in spatial epidemiology
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 ... -
The beauty of anisotropy in extraordinary transmission fishnet metamaterials
In this work, we explore both numerically and experimentally, the possibility to obtain positive and negative refraction regimes that depend on the wave polarization, exploiting the strong anisotropy of extraordinary ... -
A biased-randomized learnheuristic for solving the team orienteering problem with dynamic rewards
In this paper we discuss the team orienteering problem (TOP) with dynamic inputs. In the static version of the TOP, a fixed reward is obtained after visiting each node. Hence, given a limited fleet of vehicles and a threshold ... -
Bibliotecas amigas: abriendo puertas, conectando vidas
La autora ahonda en la metáfora de la biblioteca como puerta de acceso a multitud de dimensiones y posibilidades. -
Bizkaia en el torbellino jurídico, institucional y político de 1808 a 1814
Desde verano de 1808 Bizkaia se encuentra con el constitucionalismo español. Frente a las previsiones del napoleónico-josefino, la situación da un cambio de rumbo radical al crearse en febrero de 1810 ... -
Blind spot mitigation in phased array antenna using metamaterials
In this work, a metaradome based on a fakir’s bed of nails is designed and tested in order to suppress the blind directions of a 100-element antenna array. The antenna is a microstrip array designed to operate in X-band. ... -
Bloch surface wave resonances generated with dielectric stack of high refractive index contrast deposited on a D-shaped optical fiber for sensing applications
A 5-layer stack composed of TiO2 and Al2O3, two materials with a high refractive index contrast, was deposited on a D-shaped fiber to generate Bloch surface wave resonances with an improved figure of merit. -
Blocking time analysis of OBS routers with arbitrary burst size distribution
The blocking time distribution for an OBS router is obtained, under the assumption of Poisson-arriving bursts with Pareto, Gaussian and Exponential burst size distributions. Analytical expressions are provided as a ... -
Boresight radiation of a dipole antenna with a uniform or non-uniform left handed superstrate
In this paper measurements of the radiation performances of a dipole fed by a coaxial balun and a dipole with a left handed superstrate based on a finite periodic repetition of a unit cell are compared. Two types ... -
Brillouin distributed sensing assisted by Brillouin amplification of pump pulses
We demonstrate, for the first time to our knowledge, the extension of the measurement range of Brillouin distributed sensors (BDS) by using a distributed Brillouin amplifier (DBA) to compensate the attenuation of the ... -
Brillouin optical time-domain analysis sensor with amplification of pump pulses and tolerant to non-local effects
We demonstrate a simple technique to provide conventional Brillouin optical time-domain analysis sensor with compensation for pump pulse attenuation and tolerance to non-local effects. The technique is based on operating ... -
Brillouin optical time-domain analyzer for extended sensing range using probe dithering and cyclic coding
We present an enhanced performance Brillouin optical time-domain analysis sensor that uses dual probes waves with optical frequency modulation and cyclic coding. The frequency modulation serves to increase the probe power ... -
Brilloun optical time domain analysis sensor assisted by a Brillouin distributed amplifier
We demonstrate the extension of the measurement range of Brillouin optical time-domain analysis (BOTDA) sensors using a distributed Brillouin amplifier (DBA). The technique is based on injecting a DBA pump wave in the ... -
Building global competencies: a strategic approach to internationalization of engineering education
(Eindhoven University of Technology and Fontys University of Applied Sciences, 2023) Contribución a congreso / Biltzarrerako ekarpenaInternational mobility is an essential aspect of undergraduate education that enables students to acquire the necessary competences required by the European Higher Education Area (EHEA). However, small universities such ... -
Búsqueda de submercados inmobiliarios mediante modelos de mixturas
(Gobierno de Navarra, Departamento de Economía y Hacienda, 2003) Contribución a congreso / Biltzarrerako ekarpenaLa heterogeneidad presente en el mercado inmobiliario dificulta enormemente su análisis y puede conllevar la presencia de submercados. En este caso, el modelo clásico de regresión lineal múltiple, ampliamente utilizado ... -
Calculation of intercepted photosynthetically active radiation (IPAR) for traditional crops in Castilla y León, Spain
Agriculture is one of the most important economic activities in the Castilla y León region (Spain), approximately one-third of the land area is destined for this use. The role of agriculture in rural areas is essential ... -
Calibración y evaluación de dos métodos no destructivos de estimación de la producción en praderas polífitas con Lolium sp.
(Sociedad Española para el Estudio de los Pastos, 2012) Contribución a congreso / Biltzarrerako ekarpenaEn esta comunicación se expone el trabajo realizado para calibrar y evaluar dos métodos de estimación indirecta de la materia seca presente en praderas polífitas de Lolium sp. La comparativa metodológica se realizó entre ... -
Los canales de distribución en Navarra: estructuras, relaciones y mecanismos de comunicación
(Gobierno de Navarra, Departamento de Economía y Hacienda, 2002) Contribución a congreso / Biltzarrerako ekarpenaEl objetivo de este trabajo es ampliar, desde una perspectiva descriptiva, el conocimiento sobre el funcionamiento de los canales de distribución en Navarra en distintos sectores de actividad. Los aspectos que vamos a ... -
Capacitor current feedback active damping with lagged compensator for DFIG wind turbines with LCL filter
Several active damping strategies have been proposed in the literature for grid-connected converters with LCL filter but there are not specific strategies for DFIG wind turbines. In this system, there is an interaction ... -
Caracterización de la microestructura de piezas de fundición compacta (CGI) mediante métodos no destructivos
(Asociación Española de Ingeniería Mecánica, 2004) Contribución a congreso / Biltzarrerako ekarpenaEl desarrollo de los sistemas de inyección directa ha logrado reducir las emisiones contaminantes, y mejorar las prestaciones de los motores diesel. Pero para lograrlo se ha aumentado la presión máxima de trabajo y la ...
