Contributions to a novel remote control and configuration extension for interoperable Personal Health Devices (PHD) based on ISO/IEEE11073 standard
La norma de interoperabilidad ISO/IEEE11073 (X73) fue inicialmente concebida para entornos clínicos en el Punto de Cuidado (POC). La rama más reciente de esta norma, orientada a dispositivos de salud personal (X73PHD), ... -
Contributions to Head Pose Estimation methods
Head Pose Estimation (HPE) is currently a growing research field, mainly because of the proliferation of human-computer interfaces (HCI) in the last decade. It offers a wide variety of applications, including driver ... -
Control digital de los convertidores de cuarto orden continua continua: CUK, SEPIC, ZETA Y X
En una primera parte de esta tesis doctoral se estudian los convertidores de la clase de Cuk. Es de especial interés la deducción del convertidor X que está poco desarrollada en la literatura. Se hace el estudio de cada ... -
Control of a single-switch two-input buck converter for MPPT of two PV strings
In this paper, the Two-Input Buck (TIBuck) converter is proposed as the DC/DC stage for photovoltaic (PV) cascaded converters. This converter is attractive for this application because it is cost-effective and reliable and ... -
Control strategies to smooth short-term power fluctuations in large photovoltaic plants using battery storage systems
The variations in irradiance produced by changes in cloud cover can cause rapid fluctuations in the power generated by large photovoltaic (PV) plants. As the PV power share in the grid increases, such fluctuations may ... -
Control strategy for an integrated photovoltaic-battery system
In photovoltaic-battery systems, more attention is usually paid to the MPPT control while the battery management is put aside. This paper proposes two control strategies for an integrated PV-battery system, both of them ... -
Converging biconcave metallic lens by double-negative extraordinary transmission metamaterial
In this letter we present simulation and experimental results of a left-handed converging biconcave metallic lens made of stacked subwavelength hole arrays SSHAs working in the millimeter wave range with additional ... -
Conversión de energía en generadores eólicos con MSIP de gran potencia
Tras un primer capítulo de introducción y objetivos, en el capítulo 2 se describe el sistema analizado, explicando los diferentes elementos que lo componen. También se modeliza la MSIP y se detalla el esquema que se ha ... -
Cooperative detection applied to THz imaging cameras
THz technology for developing imaging systems has recently aroused great interest, mainly due to the large number of applications in which these frequencies can be used: security, vision in hard environments, etc. The ... -
Correlation between discharge timings of pairs of motor units reveals the presence but not the proportion of common synaptic input to motor neurons
We investigated whether correlation measures derived from pairs of motor unit (MU) spike trains are reliable indicators of the degree of common synaptic input to motor neurons. Several 50-s isometric contractions of the ... -
Corrugated horn antenna noise temperature characterisation for the NRL water vapor millimeter-wave spectrometer project
In this paper the antenna noise temperature for two different corrugated horn antennas (old model and new model) for NRL WVMS is being characterized. The whole optical system will be simulated with Ticra’s GRASP software, ... -
Cost-effective Brillouin optical time-domain analysis sensor using a single optical source and passive optical filtering
We present a simplified configuration for distributed Brillouin optical time-domain analysis sensors that aims to reduce the cost of the sensor by reducing the number of components required for the generation of the two ... -
Decoupling of multifrequency dipole antenna arrays for microwave imaging applications
The mutual coupling between elements of a multifrequency dipole antenna array is experimentally investigated by S-parameter measurements and planar near-field scanning of the radiated field. A multifrequency array with ... -
Deposition of an overlay with electrostactic self-assembly method in long period fiber gratings
It was proved that the deposition of an overlay material onto a long-period fiber grating causes important shifts in the wavelengths of the typical attenuation bands that are caused by coupling between cladding and core ... -
Desarrollo de software de simulación basado en el método numérico FDTD y su aplicación en el diseño de dispositivos de microondas miniaturizados
Esta tesis es fruto de mi participación en diferentes proyectos en algunos casos como gestor, en otras ocasiones como investigador, aunque yo diría más bien como desarrollador. La tesis la he estructurado en 4 capítulos: 1) ... -
