Assessing the effectiveness of IEEE 802.11e in multi-hop mobile network environments
2004
The IEEE 802.11e technology is receiving much interest due to the promising enhancements it offers to wireless local area networks in terms of QoS support. Until now, research has focused on single hop, access point based environments, which are the most common. We review the enhancements proposed in the last IEEE 802.11e draft (version 8.0). We analyze the performance of the IEEE 802.11e protocol on ad-hoc networks (multi-hop) in terms of throughput and end-to-end delay. We also measure the effectiveness for static and fully dynamic networks with a variable number of source stations. Finally, we analyze the performance of IEEE 802.11e when legacy IEEE 802.11 stations (no IEEE 802.11e suppo…
QoS Support for Time-Constrained Multimedia Communications in IEEE 802.11 WLANs: A Performance Evaluation
2005
During the past few years, we have been witnessing the massive deployment of IEEE 802.11 wireless LANs. Even though the widespread deployment of such wireless LANs, many studies are still underway aiming to design and develop simple yet effective QoS mechanisms for supporting time-constrained services over such platforms. In this paper, we first overview five different QoS mechanisms recently introduced in the literature as well as the upcoming IEEE 802.11e (EDCA) standard. We then carry out a comparative performance evaluation of all the QoS mechanisms. We focus our study on the effectiveness of the various QoS mechanisms for supporting time-constrained services.
La panoplia en los vasos del Tossal de Sant Miquel (Llíria). Ensayo de interpretación iconográfica
2013
The set of more than 225 vases with figurative decoration found in El Tossal de Sant Miquel (TSM), Lliria, with a chronology that it is fitted in the second stage of the Middle Iberian, between IIIrd century B.C. at the beginning of the IInd B. C, and published by first time in the Corpus Vasorum Hispanorum, offers a rich iconography in arms elements. Across his analysis it is tried to determine if a edetana panoply exists and if this one changes according to so called «Styles I and II». (Ballester, 1935, 1954; Bonet, 1995; Aranegui et alii, 1997b; Pérez Ballester, Mata, 1998; Izquierdo, Perez Ballester, 2005).El conjunto de más de 225 vasos con decoración figurada encontrados en El Tossal …
Un corpo di donna per fare la guerra. Lettura della Ifigenia in Aulide di Euripide
2009
This paper analyzes Euripides’s Iphigenia in Aulis from a perspective that highlights the relationship between three different levels - the sacred, the political and the private -intersected as they are by the opposition male/female. In the course of the tragedy we assist at the gradual domination of the two spheres of “public” and “political”, while the sphere of “sacred” provides only a ritual frame. On the other hand, from the overall structure of the tragedy it also results that the sphere of “private” relationships and loves is a loser. Iphigenia, who takes upon herself the political and patriotic values of war, peculiar to the male, allows the execution of the sacrificial ritual and h…

Entre inclusión y exclusión : trayectorias laborales juveniles en contexto de crisis
2017
En este documento de trabajo se propone un mapa analítico de las distintas tipologías de trayectorias e identidades laborales de los jóvenes en un contexto de crisis, el Mezzogiorno d'Italia. La denominación utilizada delata la identificación no solo de un espacio geográfico, el Sur de Italia, sino de un espacio semántico, de una categoría que es sinónimo de estancamiento económico y de consecuentes dificultades en la inserción de los jóvenes en el mercado del trabajo. Hemos analizado las distintas estrategias utilizadas por los jóvenes para construir su identidad y su trayectoria laboral, a la hora de incorporarse al mercado laboral en un contexto de crisis prolongada en el tiempo. El anál…
