    The communicative evaluation of Spanish in non-Spanish-speaking students of the Medical Sciences preparatory course by Adrian Abreus González, Guadalaupe García González, Nancy Castillo Mauri, Zaydelys Lucrecia Torres Calzadilla, Juan Manuel Cala Corrales

    Published 2024-07-01
    “…The most frequently errors found in students are related to poor vocabulary, both in oral and written communication. At the same time, listening comprehension constitutes the skill that had the most negative impact on student performance, due to the non-existence of some Spanish phonemes in the mother tongue of some non-Spanish-speaking students.…”

    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.…”
