Error mitigation using RaptorQ codes in an experimental indoor free space optical link under the influence of turbulence
2015
In free space optical (FSO) communications, several factors can strongly affect the link quality. Among them, one of the most important impairments that can degrade the FSO link quality and its reliability even under the clear sky conditions consists of optical turbulence. In this work, the authors investigate the generation of both weak and moderate turbulence regimes in an indoor environment to assess the FSO link quality. In particular, they show that, due to the presence of the turbulence, the link experiences both erasure errors and packet losses during transmission, and also compare the experimental statistical distribution of samples with the predicted Gamma Gamma model. Furthermore,…
The RFID technology for neurosciences: feasibility of limbs' monitoring in sleep diseases.
2009
This contribution investigates the feasibility of the passive UHF RF identification technology for the wireless monitoring of human body movements in some common sleep disorders by means of passive tags equipped with inertial switches. Electromagnetic and mechanical models as well as preliminary experimentations are introduced to analyze all the significant issues concerning the required power, the tag antenna design, the read distance, and the expected biosignals collected by the interrogation device.
Humidity Sensing by Polymer-Loaded UHF RFID Antennas
2012
Passive ultra high-frequency radio frequency identification tags, besides item labeling, are also able to exploit capability to sense the physical state of the tagged object as well as of the surrounding environment. Here, a new family of polymer-doped tags are proposed and fully characterized for the detection of ambient humidity. A sensitive chemical species based on PEDOT:PSS is used to load a shaped slot, carved into a folded-like patch tag. The communication and sensing capabilities of the resulting radio-sensor are investigated by means of simulation and measurements that show how to control and balance above opposite requirements by a proper deposition of the sensitive material. The …
Intervenciones mediáticas para la prevención del SIDA: la aproximación educación-entretenimiento
2002
Desde un punto de vista comunicativo se efectúa una revisión sobre las campañas de información contra el Sida. Dado que las campañas han mostrado fuertes limitaciones de impacto en las actitudes, se propone una nueva aproximación para el desarrollo de intervenciones mediáticas para la prevención del Sida, combinando la prevención con el entretenimiento. La aproximación Educación-Entretenimiento consiste en insertar un contenido educativo (preventivo) en mensajes destinados al entretenimiento (telenovelas, seriales radiofónicos, series de televisión, videos musicales, etc.) con el fin de incremen¬tar el conocimiento sobre el tema, generar actitudes favorables hacia la conducta preventiva y p…
Aplicación del binomio Apodemus sylvaticus /helminto como bioindicador de la regeneración del Parc Natural de la Serra Calderona (Comunitat Valencian…
2015
El estudio del binomio Apodemus sylvaticus/helminto ha sido propuesto como un bioindicador del proceso de regeneración postincendio en ecosistemas mediterráneos. El presente trabajo, enmarcado en un proyecto multidisciplinar que lleva por título “Procesos de Recuperación de Ecosistemas Perturbados por el Fuego a través del modelo Helmintos/Micromamíferos” y que fue iniciado por el grupo Parasites & Fire, del Departamento de Parasitología de la Universidad de Farmacia de la Universidad de Valencia, ofrece nuevos resultados que avalan su validación en el Parc Natural de la Serra Calderona (Comunitat Valenciana, España), la cual sufrió un devastador incendio forestal en 1992. Durante 21 años (…

Which is the best communication strategy, based on anti-tobacco ads, to impress teenagers? A multicenter cross-sectional study
2020
Background. Well-planned mass-media campaigns can increase health literacy and raise awareness about the consequences of tobacco use. This study aims to evaluate the emotions and opinions of adolescents about several anti-tobacco spots delivered by the mass media over the world. Study design. Cross-sectional study. Methods. The study was conducted in Italy in 2016–2017 among students aged 13–17 years. Students expressed their emotions and opinions about seven anti-tobacco spots from all over the world on different topics and styles. Results. 499 students attended. The video “Sponge” was found to be the most impressive (30.2%) and what they would have chosen if they had been responsible for …
"Per via di levare". Scavare e sottrarre in architettura
2014
Scavare, dal latino excavare (ex-cavare), possiede etimologicamente il significato di “rendere cavo” mediante l’azione del subtrahĕre (sottrarre). Tuttavia il significato del termine all’interno della sua necessaria disambiguazione non può essere inteso limitatamente alla luce dell’etimologia latina. Si dirà allora che la tecnica dello scavo è opposta e complementare alla tecnica dell’accumulazione. È un procedere per sottrazione di volumi, un operare in negativo per asportazione di materiale, erodendo, cavando ed estraendo. Il saggio indaga, attraverso un intenso per quanto lacunoso excursus tra le esperienze della contemporaneità l'emergere del archetipico della dimensione ipogea dell’arc…
Lluís Ferran de Pol and Concentrationary Literature: From Campo de concentración to Un de tants
2011
This article analyses the different rewritings that Catalan writer Lluis Ferran de Pol (Arenys de Mar, 1911-1995) published of his most important concentrationary memories. Ferran de Pol was interned in French concentration camps during the first months of 1939. As a result of his confinement, he wrote Campo de concentracion, a book written in Spanish and published in the Mexican newspaper El Nacional during his exile in Mexico. Back in Catalonia in the early 1960s, he rewrote these prose pieces into Catalan and published them under the title De lluny i de prop (1973). In 2009 this work saw another edition in Catalan under the title Un de tants, edited by Josep-Vicent Garcia.
Cyber-Activism Against Sexual Violence: #BringBackOurGirls
2020
En els últims anys, les campanyes digitals s’han convertit en eines potents de denúncia i defensa de les violències contra les dones. El seguiment massiu en demostra l’èxit. No obstant això, continuem preguntant-nos sobre els límits i les oportunitats d’aquests instruments, especialment en àrees de conflicte i violència extrema. En aquest article, a través d’una etnografia digital i de l’anàlisi de les dades de l’activisme en la xarxa social Twitter, explorem l’impacte de la campanya #BringBackOurGirls, que es va iniciar per a reclamar l’alliberament de 276 xiquetes segrestades pel grup terrorista nigerià Boko Haram a la ciutat de Chibok. Els resultats de la nostra investigació indiquen que…
