Double-port slotted-antenna with multiple miniaturized radiators for wideband wireless communication systems and portable devices
(Electromagnetics Academy, 2019)
info:eu-repo/semantics/article,
Proof-of-concept is presented of a novel slot antenna structure with two excitation ports. Although this antenna provides a wide impedance bandwidth, its peak gain and optimum radiation efficiency are observed at its ...
Actividad electromiográfica (EMG) durante el pedaleo, su utilidad en el diagnóstico de la fatiga en ciclistas
(SEMED - FEMEDE, 2017)
info:eu-repo/semantics/article,
La fatiga muscular tiene múltiples definiciones, pero con una misión especial cual es la misión protectora, avisando al organismo
sobre la debilidad o la aparición de una incapacidad funcional. En esta revisión se hace ...
Using S-parameter measurements to determine the threshold voltage, gain factor, and mobility degradation factor for microwave bulk-MOSFETs
(Elsevier, 2011)
Artículo / Artikulua,
In this paper, we present an extraction and characterization methodology which allows for the determination, from S-parameter measurements, of the threshold voltage, the gain factor, and the mobility degradation factor, ...
Modeling and parameter extraction of test fixtures for MOSFET on-wafer measurements up to 60 GHz
(Wiley, 2013)
Artículo / Artikulua,
We present a circuit model and parameter determination methodology for test fixtures used for on-wafer S-parameter measurements on CMOS devices. The model incorporates the frequency dependence of the series resistances and ...
Magnetic human body communication based on double-inductor coupling
(IEEE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
This paper proposes a new technique for Human Body Communication (HBC) that uses the magnetic coupling in transmitter and receiver. A discussion about the presence of parasitic paths, when magnetic coupling is used in the ...
Second-order nonlocal effects mitigation in Brillouin optical time-domain analysis sensors by tracking the Brillouin frequency shift profile of the fiber
(IEEE, 2017)
Artículo / Artikulua,
We report on an additional limitation that has been found in Brillouin optical time-domain analysis (BOTDA) sensors due to the so-called second-order nonlocal effects (NLE). Second-order NLE appear in BOTDA setups that ...
A comparative study of degradation and performance of thin film photovoltaic generators versus a multi-crystalline generator
(2013)
info:eu-repo/semantics/conferenceObject,
Thin film solar cells (TFSC) are supposed to have higher energy yield rates than crystalline silicon (Si-x) mainly possible by some enhancements like lower temperature coefficient and higher absorption of diffuse light. ...
A novel camera phone-based platform for Sol-Gel-derived fluorescence pH sensing
(2013)
info:eu-repo/semantics/conferenceObject,
In this work a novel camera phone system for fluorescence-based sol-gel-derived pH sensing is presented. The sol-gel based pH material, a microfluidic chip and a camera phone have been combined to obtain a fluorescence-based ...
Optical sensor based on polymer electrospun nanofibers for sensing humidity
(2011)
info:eu-repo/semantics/conferenceObject,
A novel humidity sensor based on polymer electrospun nanofibers coating onto an optical fiber is proposed in this work. The coating is composed of poly(acrylic acid), and its fabrication was performed by the electrospinning ...
Humidity sensor based on a long-period fiber grating coated with a hydrophobic thin film
(2010)
info:eu-repo/semantics/conferenceObject,
In this work it is proposed a novel fiber optic humidity sensor based on a functionally coated long-period fiber grating (LPG). The coating is composed of tetraorthosilicate matrix functionalized with perfluorooctyltriethoxysilane ...
