Analysis of radio wave propagation for ISM 2.4GHz wireless sensor networks in inhomogeneous vegetation environments
(2014)
Contribución a congreso / Biltzarrerako ekarpena,
The use of wireless networks has been extended in an exponential growing due to the improvement in terms of battery life and low consumption of the devices. However, it is highly important to conduct previous radio propagation ...
Otras trayectorias de vida: mujeres sin maternidad
(2014)
Contribución a congreso / Biltzarrerako ekarpena,
La antropología de género ha prestado escasa atención a las mujeres que no son madres. Este vacío analítico e incluso conceptual comenzó a ser paliado por algunas autoras (Debest, 2013; Piella, 2011; Badinter, 2010; Ávila, ...
Static and dynamic characterization of a supercapacitor
(2014)
info:eu-repo/semantics/conferenceObject,
Supercapacitors (SCs) have recently received a major boost as a result of the development of multiple applications, such as the electric vehicle and electric microgrids. Storage systems consisting of SCs combined with ...
Ecosistemas. Una propuesta colaborativa de “aprendizaje basado en proyectos” para 4º ESO
(Publicaciones Universidad de Huelva, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Presentamos una propuesta didáctica de Aprendizaje Basado en Proyectos
sobre "La transformación de los ecosistemas" (Biología y Geología; 4º ESO). Titulada "Protegemos nuestro entorno", finaliza con la redacción de un ...
Brillouin distributed sensing assisted by Brillouin amplification of pump pulses
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
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 ...
Phasorial DPP-BOTDA sensor tolerant to non-local effects
(SPIE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
We introduce a modification of the differential pulse width pair technique in a BOTDA sensor based on a phase modulated probe wave and RF demodulation. This provides a differential Brillouin phasorial signal with high ...
Polarization diversity for Brillouin distributed fiber sensors based on a double orthogonal pump
(SPIE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a novel Brillouin optical time domain analysis sensor deploying a polarization diversity technique which eliminates the need for polarization scrambling, providing measurements that are largely immune to the ...
Synthesis of virtual Brillouin frequency shift profiles in BOTDA sensors using optical source dithering
(SPIE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a novel concept for Brillouin optical time domain analysis sensors that is based on synthesizing a virtual Brillouin frequency shift profile along the sensing fiber. The technique is based on modulating the ...
Dirección de proyectos en intervenciones de cooperación al desarrollo. Organizaciones no gubernamentales
(2014)
Contribución a congreso / Biltzarrerako ekarpena,
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 ...
Comparison of linear and and small-signal models for inverter-based microgrids
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Frequency and voltage regulation in droop-based microgrids is generally modeled using small-signal analysis. In order to ensure accuracy, existing models do not decouple real and reactive power responses. However, the ...
