    Error Analysis of Business English Translation Based upon Functional Theory
    (Scientific Research Publishing, 2016-07) Zhang, Lili
    The functional theory of translation, with Skopostheorie as a core, advocates that the translation process should not only be based upon equivalence but more importantly upon the prospective functions or Skopos of the target text. Translation errors study was also put forward and carried out as a result. Based on the explanation of this translation theory, this paper makes a thorough analysis of business English translation errors, with the major reasons raised and corresponding solutions and strategies presented. Besides shedding lights on the theoretical study of translation in this field, the analysis aims to play a positive role in improving the substantial quality of business English translation in practice.

    A New Adaptive EDCA Approach to QoS of Wireless Communications
    (Scientific Research Publishing, 2010-07) Wang, Huibin; Hu, Yang; Zhang, Lili; Xia, Wei
    Under the background of intelligent transportation application, QoS for various services is different in wireless com-munication. Based on the MAC layer protocol, this paper analyzes the QoS in IEEE 802.11 MAC protocol framework, and proposes a new design of a Differentiation Enhanced Adaptive EDCA (enhanced distribution channel access) approach. The proposed approach adjusts the window zooming dynamically according to the collision rate in sending data frames, makes random offset, and further distinguishes the competition parameters of the data frames that have the same priority, so as to reduce the conflict among the data frames, and improve the channel utilization. Experiments with different service cases were conducted. The simulation results show that: comparing with the conventional EDCA method, the proposed approach can ensure that high priority services are sent with priority, and the overall QoS is highly improved.
