Description and properties of curve-based monotone functions
Curve-based monotonicity is one of the lately introduced relaxations of monotonicity. As directional monotonicity regards monotonicity along fixed rays, which are given by real vectors, curve-based monotonicity studies the ... -
Desfasadores para microstrip empleando metamateriales
In this paper an application of LH materials at microwave frequencies (10GHz) is presented. A compact quarter-wave impedance transformer is proposed using alternating sections of left handed media (LHM) and conventional ... -
Design alternatives for a submm-wave Fabry-Perot cavity antenna
This paper discusses different design alternatives for a high gain planar antenna at 240 GHz. The antenna is based on a Fabry-Perot configuration, where two different partial reflection surfaces (PRS) are considered: a ... -
Design and optimization of the dies for the isothermal forging of a cam
In the present study, the design of the dies required for the isothermal forging of a cam is analysed by finite volume method. Specifically, cams are of great importance in automotive industry, where a lower weight and ... -
Design exploration prior to blade multi-disciplinary optimisation
The approach of designing blades as a multi-disciplinary, holistic optimisation implies significant challenges owing to the high complexity of the involved factors such as aerodynamics, elasticity, controller and loads. ... -
Design of a groove gap waveguide to microstrip inline transition
In this paper the design of an inline transition between microstrip and groove gap waveguide operating at Wband is presented. The transition consists of two sections: a tapered microstrip line and a Chebyshev transformer. ... -
Design of a multifrequency antenna array with the use of left-handed superstrates
In this paper, the radiation performances of different antenna configuration based on Left-Handed superstrates are presented. First of all, the behaviour of a Left- Handed (LH) unit cell is analysed, showing a resonant ... -
Design of a planar meta-surface based on dipoles and wires for antenna applications
In this paper, the design of a planar meta-surface based on dipoles and wires is presented. The unit cell is formed by three independent layers, which contain two parallel dipoles and one wire. The behaviour of these ... -
Design of a slotted Substrate Integrated waveguide antenna using a metasurface
In this paper, the use of a metasurface to improve the radiation properties of a Substrate Integrated Waveguide based slotted antenna is proposed. The design process of a metasurface covered 8 element slot antenna array ... -
Design of low-cost smart accelerometers
The goal of this project is to design a low-cost smart accelerometer, making use of a piezoelectric element as basic sensing material, and adding a mixed-mode conditioning circuit. -
Design of multi-layered radiative cooling structures using evolutionary algorithms
In this work we present a novel way to design thinfilm radiative cooling metamaterials based on genetic algorithms. Three simulations with different design constraints have been done, resulting in three structures that ... -
Designing antenna systems with CORPS (coherently radiating periodic structures)
In this paper a new philosophy to design antenna systems is presented. It is based on the recently proposed Coherently Radiating Periodic Structures (CORPS). These structures are essentially a periodic structure which ... -
Designing feeding networks with CORPS: coherently radiating periodic structures
The design of feeding networks in phased array systems results tricky since all the complex excitations should be provided to all the radiating elements of the system. Where the number of radiating elements increases the ... -
Desigualdades de género y representaciones sociales de la movilidad espacial en el área metropolitana de Pamplona-lruñea
La movilidad espacial en las metrópolis contemporáneas constituye un fenómeno estratégico para pensar la realidad cotidiana en su compleja red de relaciones, en la pluralidad de significados y prácticas de coordinación y ... -
El despliegue de la red urbana en Navarra. Espacios y movilidad entre el Adour y el Ebro (ss. XI-XIII)
(Gobierno de Navarra. Institución Príncipe de Viana, 2015) Contribución a congreso / Biltzarrerako ekarpenaEl presente trabajo se ocupa de la génesis del desarrollo urbano de Navarra, considerando como núcleos urbanos a aquellos que reciben un estatuto de franquicia. El espacio atendido se amplia al territorio entre ... -
Detección de congestión en la Internet europea
In this paper we present a study about the utilization of one-way delay measurements to detect and characterize network congestion in the european Internet. The experiments have been made using the ETOMIC platfom that ... -
Detecting disruption periods on TCP servers with passive packet traffic analysis
This paper presents a simple passive algorithm to monitor service availability. The algorithm is based on packet counting over a passive traffic trace of a population of clients accessing servers of interest. The major ... -
Detection of ethanol in human breath using optical fiber long period grating coated with metal-organic frameworks
An optical fiber sensor for ethanol detection in exhaled breath has been developed. It has been fabricated by functionalizing a Long Period Grating with a metal-organic framework, ZIF-8. The sensor’s response was tested ... -
Determining an optimal area to locate a biorefinery under economic and environmental criteria
Facilities location is a strategic decision which has to be carefully considered because it could involve the failure or success of a business. For that reason, anything that helps decision makers to facilitate their ... -
Detrimental effects in Brillouin distributed sensors caused by EDFA transient
We investigate the deleterious effect and the error in Brillouin optical time-domain analyzers induced by the combination of a low extinction ratio pulse generation with the transient behavior of erbium-doped fiber amplifiers.
