Multi-user interference mitigation under limited feedback requirements for WCDMA systems with base station cooperation
2016
One of the techniques that has been recently identified for dealing with multi-user interference (MUI) in future communications systems is base station (BS) cooperation or joint processing. However, perfect MUI cancellation with this technique demands severe synchronization requirements, perfect and global channel state information (CSI), and an increased backhaul and signaling overhead. In this paper, we consider a more realistic layout with the aim of mitigating the MUI, where only local CSI is available at the BSs. Due to synchronization inaccuracies and errors in the channel estimation, the system becomes partially asynchronous. In the downlink of wideband code division multiple access …
La acción social ante la crisis global
2010
La crisis global exige profundas mutaciones en todos los subsistemas de la sociedad, y requiere de nuevas conceptualizaciones, mapas conceptuales y transiciones técnicas en el ámbito de la intervención social. A partir de las convulsiones del Estado de Bienestar, de las reducciones presupuestarias, del aumento de las demandas en situación de emergencia, de las exigencias de la cultura actual del derecho y de los procesos de mundialización, se recrea el lugar de la acción social: como atención a las privaciones, despliegue de las capacidades y fomento de la acción conjunta. Asimismo, se necesita abrir la acción social a distintos actores: al Estado con sus administraciones, al mercado con su…
L-Band vegetation optical depth for crop phenology monitoring and crop yield assessment
2018
Vegetation Optical Depth (VOD) at L-band is highly sensitive to the water content and above-ground biomass of vegetation. Hence, it has great potential for monitoring crop phenology and for providing crop yield forecasts. Recently, the Multi-Temporal Dual Channel Algorithm (MT -DCA) has been proposed to retrieve L-band VOD from Soil Moisture Active Passive (SMAP) measurements. In previous research, SMAP VOD has been compared to crop phenology and has been used to derive crop yield estimates. Here, we review and expand these initial research studies. In particular, we quantify the capability of VOD to detect different crop stages, and test different VOD metrics (i.e., maximum, range and inte…
Empathy, emotional intelligence, and communication in Nursing: The moderating effect of the organizational factors
2020
Objective: to evaluate the relation and the moderating effect of the organizational factors on the attitudes towards communication, empathy, and emotional intelligence in the nurses. Method: a cross-sectional study was conducted with a convenience sample of 268 nurses from Valencia, Spain. The attitudes towards communication were evaluated by means of the specifically designed instrument, those towards empathy with the Jefferson’s Scale of Empathy for Nursing Students, and those towards emotional intelligence by means of the Trait Meta-Mood Scale, consisting of 24 items. The effect of the studied variables was assessed by means of ANOVA, multiple linear regression models were applied, and t…
