    “INFINITO ENQUANTO DURE”: a confiança nas relações amorosas à luz de Anthony Giddens1 by Marcela Zamboni

    Published 2013-03-01
    “…Aqui, o conceito de confiança servirá para pensar as relações afetivo-conjugais. Para tanto, este trabalho será estruturado da seguinte forma: 1) a confiança na alta modernidade; 2) das formas de amar: rupturas e continuidades; e 3) amor e autoidentidade: os manuais de autoajuda e a terapia. …”

    Full-Duplex Mode in Amplify-and-Forward Relay Channels: Outage Probability and Ergodic Capacity by Rongyi Hu, Chunjing Hu, Jiamo Jiang, Xinqian Xie, Lei Song

    Published 2014-01-01
    “…This paper investigates the outage probability and ergodic capacity performances for full-duplex mode in two-way amplify-and-forward relay channels. The two-way relay channels which consist of two source nodes and a single relay node working in full-duplex mode, are assumed as independent and identically distributed as Rayleigh fading. …”

    Performance analysis of multi-relay DF cooperative communication system based on directional antenna by Mingwei WANG, Huisheng ZHANG, Lixin LI, Lifeng HE

    Published 2016-06-01
    “…In order to achieve reliable communication in multi-relay cooperative communication,the directional antenna combining multi-relay cooperative communication system and optimal relay selection decode-and-forward cooperative strategy was presented.Firstly,the theoretical closed form of outage probability of the communication system using directional antenna operating in the three modes of DT-DR,DT-OR and OT-OR were presented.Then for three kinds mode,the collaboration communication system interrupt probability and signal-to-noise ratio,the number of relay nodes,the antenna gain channel fading efficiency and relationship between the channel capacity were analyzed in numerical simulation.These findings reveal that excellent performance of cooperative communication system with directional antennas could be achieved such as smaller outage probability and improved by best relay nodes and optimal power allocation coefficient.…”

    Security versus reliability analysis for multi-eavesdropper cooperation wireless networks with best relay by Mei-ling LI, Zeng-shou DONG, Gang-fei WANG, Zhao-ming LU

    Published 2017-10-01
    “…Physical-layer security could be used to effectively combat eavesdroppers and the transmission reliability of the main link could be improved.A wireless relay network with multiple both decode and forward eavesdroppers and relays were considered,in the presence of the link from source to destination.A best relay selection scheme based on multieavesdropper’s cooperation was proposed,and the outage probability and the intercept probability was deduced under both schemes without relay and with best relay.Then,the security and reliability influenced by different relay selection schemes were analyzed.The simulation results show that the achievable channel capacity at the destination node and the system outage probability are directly affected by different relay selection scheme.Lower system outage probability can be achieved by the proposed scheme,and the system outage probability and intercept probability are both decreased with the increase of the number of relays.The intercept probability increases with the increase of the number of eavesdroppers,which,however,can be reduced by increasing the number of relays to ensure the main link’s reliable transmission.…”
