Las dinámicas de las políticas sociales públicas en Navarra (1982-2002)
(Gobierno de Navarra, Departamento de Economía y Hacienda, 2003) Contribución a congreso / Biltzarrerako ekarpenaEn esta ponencia, se repasa la situación en el año 2000 (que es el último del que Eurostat ofrece datos por países) de España en el conjunto de los 15 países que conformaban la Unión Europea en lo referente a gastos de ... -
Dipolos y metamateriales: mejora de las características de radiación
In this work, pass band properties of Left Handed Media (LHM) are demonstrated. These properties have been used in order to make a LHM super-substrate that is put over a dipole antenna. This super-substrate is going to ... -
Dirección de proyectos en intervenciones de cooperación al desarrollo. Organizaciones no gubernamentales
Propósito — En este artículo se analiza la adopción de prácticas del Project Management en organizaciones no gubernamentales del sector de la Cooperación al Desarrollo, y su influencia en el desempeño de los proyectos. Se ... -
Directions of directional, ordered directional and strengthened ordered directional increasingness of linear and ordered linear fusion operators
In this work we discuss the forms of monotonicity that have been recently introduced to relax the monotonicity condition in the definition of aggregation functions. We focus on directional, ordered directional and strengthened ... -
Discrete lenses for multibeam applications
The capability of having many different beams illuminating the earth surface from a geostationary satellite has been an issue of interest during the last few years. The need of increasing the services provided ... -
Diseño de alimentadores optimizados para la cámara anecoica de la Universidad de Limoges
In this paper, high technology optimized feed horn designs are presented. These feed horns have been designed to improve the quite zone size and behaviour of the CATR of the CREAPE research team at Limoges University. Very ... -
Diseño de filtros banda rechazada usando Defected Ground Structures (DGS)
In this paper a type of Defected Ground Structure (DGS) is studied and used to implement filters in microstrip technology. It is first demonstrated that the main parameter which controls its operation is the external ... -
Diseño de filtros en guía rectangular usando estructuras PBG's
A new application of dielectric periodic structures (also known as PBG) to build and design waveguide filters is presented. The periodic structures have some stop frequency bands, band gaps, defined by the geometry, ... -
Diseño de filtros paso bajo usando Defected Ground Structures (DGS)
In this paper a new method of trully design of filters using Defected Ground Structures is proposed. It makes use of the model proposed in previous developments by the same authors and simplifies it to a first-order model ... -
Diseño de un mecanismo de propulsión para bicicleta capaz de almacenar y descargar energía mecánica producida por el usuario
La energía eléctrica todavía proviene en su mayor parte de combustiones fósiles y soluciones no ecológicas. En este artículo se describe una alternativa a la bicicleta eléctrica. Se muestra el proceso de diseño de un ... -
Diseño de una antena dual gaussiana de doble profundidad de corrugación
In this paper a new design of a dual-band corrugated horn antenna is presented. The design is based on a gaussian profile to allow high pattern symmetry, low-crosspolar levels and low-side-lobes over a wide frequency range. ... -
Diseño óptimo de antenas de bocina multimodo para excitar un haz gaussiano fundamental de alta pureza
In this paper, we present an original and optimal multimode horn antenna design to excite the fundamental Gaussian beam from an overmoded waveguide. In particular, we focus the study in overmoded circular corrugated ... -
Diseño robusto de filtros paso-banda de banda W en tecnología Gap Waveguide impresos en 3D
A 3D-printed bandpass filter for the W-band is proposed in this work. The use of the higher-order TE10n modes in groove gap waveguide (GGW) technology is analyzed and shown to ease the manufacturing requirements. The design ... -
Diseño y caracterización de reflectores incoherentes de retrodispersión de fibra microperforada para láseres random de fibra óptica
Los láseres random de fibra óptica presentan una serie de características que los hacen idóneos para una gran variedad de aplicaciones industriales. La elevada longitud de fibra necesaria en la cavidad debido a sus bajos ... -
Diseño y medida de una antena choke-gaussiana
A new design of corrugated horn antenna for global earth coverage from a geostationary satellite to obtain very low sidelobes and crosspolar levels with a really compact design in a quite wide bandwidth is presented in ... -
La disposición adicional primera de la Constitución de 1978 en las Cortes
Tras examinar la reivindicación de los derechos históricos vascos durante la Restauración y la Segunda República, el trabajo se centra en su tratamiento en la Constitución de 1978. La propuesta inicial del PNV ... -

Dissimilarity based choquet integrals
In this paper, in order to generalize the Choquet integral, we replace the difference between inputs in its definition by a restricted dissimilarity function and refer to the obtained function as d-Choquet integral. For ... -
Distance transformations based on ordered weighted averaging operators
Binary image comparison has been a study subject for a long time, often rendering in context-specific solutions that depend upon the type of visual contents in the binary images. Distance transformations have been a recurrent ... -
Distributed humidity sensor for moisture-front monitoring in soils
In this contribution, high spatial resolution distributed humidity sensing was demonstrated for moisture-front monitoring in soils by using polyimide coated optical fiber.
