Los efectos de la Ley de 21 de julio de 1876 en la evolución de la foralidad navarra (1876-1927)
Navarra había aceptado la adecuación de su sistema de gobierno pre-liberal a la Ley de 1839, por medio de la de 1841, lo que no habían realizado las diputaciones de las «provincias exentas», a las que se impuso ... -
Effect of the inner current loop on the voltage regulation for three-phase photovoltaic inverters
In three-phase grid-connected PV inverters, regulating the input voltage is a fundamental requirement. In order to reduce the influence of the PV non-linear behavior and ensure stability in the whole operating range, the ... -
Effective analysis of secure web response time
The measurement of response time in web based applications is a common task for the evaluation of service responsiveness and the detection of network or server problems. Traffic analysis is the most common strategy for ... -
Effective burst preemption in OBS network
Burst preemption is the most effective technique to provide Quality of Service (QoS) differentiation in Optical Burst Switching (OBS) networks. Nonetheless, in conventional OBS architectures, when preemption happens the ... -
An efficient algorithm for the evaluation of tonality and the determination of the tonal frequency according to IEC 61400-11
The terms of tonality and tonal audibility of the noise emitted by wind turbines are defined and described in the standard IEC 61400-11. The procedure for tonality assessment at different wind speeds based on the narrowband ... -
Efficient implementation of GALS systems over comercial synchronous FPGAs: a new approach
This paper introduces a new approach for implementing Glocally Asynchronous – Locally Synchronous (GALS) systems over commercial available Field Programmable Gate Arrays (FPGA). This new vision is aimed to overcome the ... -
Egituren egoeraren monitorizaziorako zuntz optikoan oinarritutako sentsore sinplifikatua
Brillouin hedatuko denbora eremu optikoaren analisian (BOTDA) oinarritutako sentsoreak, estruktura handien (100 km luzerako estrukturak) deformazioa eta tenperatura neurtzeko gaitasuna dute. Lan honetan, BOTDA konfigurazio ... -
La elaboración de la ley de 25 de octubre de 1839
El 31 de agosto de 1839 se firmó en Bergara un Convenio entre loos generales Espartero y Maroto que finalizó la guerra carlista con un compromiso de reconocimiento de los Fueros Vascos. Con esa finalidad el Gobierno de ... -
Las eléctricas: la clave de bóveda de la Transición Energética en España (1969-2020)
A pesar de la esperanza depositada en una transición global dirigida desde las instituciones, las compañías eléctricas han marcado los ritmos de cambio en la forma de generación de electricidad desde los inicios del sector. ... -
Electrospinning technique as a powerful tool for the design of superhydrophobic surfaces
The development of surface engineering techniques to tune-up the composition, structure, and function of materials surfaces is a permanent challenge for the scientific community. In this chapter, the electrospinning ... -
La élite de poder navarra (1999-2003): una aproximación posicional
En este trabajo se hace una exposición y explicación de los resultados de la investigación sobre la élite de poder navarra, utilizando como herramienta de trabajo el enfoque posicional. -
Embedded pairs of fractional step Runge-Kutta methods and improved domain decomposition techniques for parabolic problems
In this paper we design and apply new embedded pairs of Frac- tional Step Runge-Kutta methods to the e±cient solution of multidimensional parabolic problems. These time integrators are combined with a suitable split- ting ... -
An empirical study on supervised and unsupervised fuzzy measure construction methods in highly imbalanced classification
The design of an ensemble of classifiers involves the definition of an aggregation mechanism that produces a single response obtained from the information provided by the classifiers. A specific aggregation methodology ... -
Energy harvesting approaches in IoT scenarios with very low ambient energy
(European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ), 2019) Contribución a congreso / Biltzarrerako ekarpenaThe feasibility of multi-source energy harvesting in Internet of Things (IoT) scenarios with low and intermittent ambient energy is addressed. As a relevant case study, application to a smart cargo container system is ... -
An engagement-based school experience as a premise of wellbeing
In the challenge of providing a quality education to all students, one of the main driving forces of change is the teacher and his/her attitudes; the need to address inclusion and participation of everyone therefore affects ... -
Enhanced optical fiber lasers and optical fiber sensors assisted by micro-drilled optical fibers
Enhanced OFS assisted by micro-drilled optical fibers acting as mirrors are demonstrated. Strain sensitivity improved more than one order of magnitude in comparison with FBG sensors using a 50 μm-waist micro-drilled taper ... -
Enhanced radiation properties of a rectangular waveguide by means of a left handed media
In this paper, the results of experimental investigations to improve the gain between two antennas by means of a Left Handed Material (LHM) are presented. The basic idea is the use of a LHM media acting as a resonator ... -
Enhanced tolerance to pulse extinction ratio in Brillouin optical time domain analysis sensors by dithering of the optical source
We demonstrate the relaxation of the stringent requirements placed on the pulse extinction ratio in long-range Brillouin optical time-domain analysis sensors (BOTDA) by modulating the wavelength of the laser source that ... -
Enhancement of signal-to-noise ratio in Brillouin optical time domain analyzers by dual-probe detection
We demonstrate a simple technique to enhance the signal-to-noise ratio (SNR) in Brillouin optical time-domain analysis sensors by the addition of gain and loss processes. The technique is based on the shift of the pump ... -
