Radiación solar: principios, evaluación y aprovechamientos
En esta lección se tratará la radiación solar desde un punto de vista energético. En concreto, tras una obligada introducción en la que se establecerá su carácter, se pondrá de manifiesto su importancia para la humanidad ... -
Radiation performances of a dipole array configuration inserted in a left-handed media
In this work, the radiation improvements achieved when Left Handed Media (LHM) are combined with dipole antennas has been analysed. The behavior of two dipole antennas in array configuration when a Left Handed superstrate ... -
Radiation performances of a multifrequency dipole antenna array with a left handed superstrate
In this paper, the radiation performances of a multifrequency antenna array (MFAA) which consists of two dipoles (1 and 3) that are radiating at 9.57 GHz and other one (dipole 2) radiating at 11.98 GHz are presented. In ... -
A radio channel model for D2D communications blocked by single trees in forest environments
In this paper we consider the D2D (Device-to-Device) communication taking place between Wireless Sensor Networks (WSN) elements operating in vegetation environments in order to achieve the radio channel characterization ... -
Radio characterization for ISM 2.4 GHz wireless sensor networks for judo monitoring applications
In this work, the characterization of the radio channel for ISM 2.4GHz Wireless Sensor Networks (WSNs) for judo applications is presented. The environments where judo activity is held are usually complex indoor scenarios ... -
La radio escolar
El presente Trabajo de Fin de Grado acerca de la radio escolar, pretende ser un ejemplo de cómo una herramienta tecnológica como un blog, puede ser el soporte de programas radiofónicos elaborados por el alumnado, ... -
Radio wave propagation and WSN deployment in complex utility tunnel environments
The significant growth of wireless communications systems in the last years has led to the adoption of a wide range of applications not only for the general public but, also, including utilities and administrative authorities. ... -
Radioenlace hospital de Estella-Silo
Actualmente, la demanda de capacidad que requieren los hospitales para transmitir las diferentes pruebas médicas, como son TACs y resonancias entre otras, ha aumentado considerablemente. La empresa pública NASERTIC, se ... -
Radiología innecesaria en Atención Primaria
Fundamento: La solicitud de pruebas diagnósticas desde atención primaria presentan un aumento progresivo en el tiempo y una gran variabilidad interpersonal en su solicitud, que sugiere que se están aplicando servicios ... -
Rafael Mieza Mieg (1945-2015): in memoriam
Recorrido por la vida y obra del historiador del País Vasco Rafael Mieza Mieg con motivo de su fallecimiento el 27 de septiembre de 2015. -
The rainbow. A project to develop mathematical contents in Early Childhood Education
Este trabajo de fin de estudios se centra en la didáctica matemática dentro de la etapa educativa del segundo ciclo de Educación Infantil. Para poder poner en práctica los contenidos y procesos propios de esta disciplina ... -
Raising the accuracy of shadow economy measurements
En este artículo se estima el tamaño de la economía sumergida en una región española (Navarra) para el período 1986-2016. Se han empleado métodos macroeconométricos indirectos, como el enfoque de Demanda de efectivo, dos ... -
Ramp-rate control in large PV plants: battery vs. short-term forecast
The changeability in the power produced by utility-scale PV plants caused by shadows due to passing clouds can compromise grid stability. Traditionally, some kind of energy storage systems (ESS) is proposed as the solution ... -
Random DFB fiber laser for remote (200 km) sensor monitoring using hybrid WDM/TDM
In this paper, a random distributed feedback fiber laser is proposed as a multiplexing scheme for ultralong range measurements (up to 200 km). Optical fiber sensors are time and wavelength multiplexed overcoming one of the ... -
Random fiber lasers: application to fiber optic sensors networks
Recently, random mirrors have been proposed as a method to create fiber laser cavities. This kind of cavity is based on cooperative Rayleigh scattering, which is generated along a fiber due to the material inhomogeneities ... -
Random subwavelength structures on glass to improve photovoltaic module performance
Glass samples have been processed by a single-step self-masking RIE (Reactive Ion Etching) process to obtain random subwavelength structures (SWSs), which mimic anti-reflective and anti-soiling patterns present in nature. ... -
Rank dependent expected utility in the pelota betting system: an experiment
We theoretically and experimentally study a zero sum betting market: the pelota betting system, but with commonly known objective probabilities and without commissions. We know that risk-averse expected utility maximizers ... -
Ranking opportunity profiles through dependent evaluation of policies
Rankings to evaluate opportunity distributions present in most of the literature judge a policy (change from one distribution of opportunities to another) on the basis of the changes created and, thus, independently ...
