从知识管理看翻译中文化信息的失落与变形     

张莉 《黄河科技大学学报》2006,8(4):95-97

知识管理是企业界一个新的管理理念。将知识管理的理念应用于翻译,讨论文化传递中文化信息的失落与变形是一个较新观点。翻译的过程是知识管理的过程,任何文化信息的失落与变形都是知识管理的结果。如果异域文化的产品被当做资产来管理、利用、创造和投资,那么对翻译的知识管理将会变得积极和敏锐。  相似文献   

Mathematical Analysis of Energy Efficiency in IEEE 802.11 DCF     

高波杨宇航  马惠业 《天津大学学报(英文版)》2005,11(5):332-337

The standardized IEEE ,802. II distributed coordination function （ DCF） provides a contention-based distributed channel access mechanism for mobile stations to share the wireless medium. However, when stations are mobile or portable units, power consumption becomes a primary issue since terminals are usually battery driven. This paper proposes an analytical model that calculates the energy efficiency of both the basic and the RTS/CTS access mechanisms of the IEEE 802. II protocol. The model is validated with simulation results using NS-2 simulation package. The effects of the network size, the average packet length, the initial contention window and maximum backoff stages on the energy efficiency of both access mechanisms are also investigated. Results show that the basic scheme has low energy efficiency at large packet length and large network size, and depends strongly on the number of stations and the backoff procedure parameters. Conversely, the RTS/CTS mechanism provides higher energy efficiency when the network size is large, and is more robust to variations in the backoff procedure parameters.  相似文献   

《说文解字》“心”部字的文化阐释

《说文解字》的“心”部字在一定程度上反映了汉民族的思想文化传统。通过对“心”与思维、情感的关系以及古代哲学对“心”认识的阐释,我们可以管窥中华思想的独特性与传承性。  相似文献   

A novel method for mobile robot simultaneous localization and mapping   总被引：2，自引：0，他引：2  

LI Mao-hai HONG Bing-rong LUO Rong-hua WEI Zhen-hua 《浙江大学学报(A卷英文版)》2006,7(6):937-944

INTRODUCTION A key prerequisite for a truly autonomous robot is that it can simultaneously localize itself and accu-rately map its surroundings (Kortenkamp et al., 1998), which is known as Simultaneous Localization and Mapping (SLAM), which, when phrased as a state estimation problem, involves a variable number of dimensions. Murphy and Russell (2001) adopted Rao-Blackwellized particle filters (RBPFs) as an effective way for representing alternative hypotheses on robot paths and ass…  相似文献   

从"上海五国"机制到"上海合作组织"进程:非传统安全视角分析     

岳爱武  牛天秀 《金陵科技学院学报(社会科学版)》2005,19(3):15-19

冷战结束后，传统军事安全因素对国际社会秩序的威胁程度大大降低，而由非传统安全威胁引发地区性骚乱和冲突的危险性明显上升。在从“上海五国”机制发展为“上海合作组织”的进程中，各相关国家在成功解决共同面临的军事安全问题后，即转入到对恐怖主义、极端主义、分裂主义等恶势力的打击，并推动相互间的合作向经济、文化、社会保障等更广泛的领域中扩展。非传统安全的特征，要求“上海合作组织”树立综合安全观，发展以互利合作为主题的新型国家关系，逐渐成为一个更具开放性的组织。  相似文献   

丝素改性胶原膜的肝素化     

冯桂龙 《襄樊学院学报》2004,25(2):39-42

以1-(3-二甲氨基丙基)-3-乙基碳二亚胺(简称EDCI)为缩合剂对丝素改性胶原膜进行了肝素固定化,用X光电子能谱分析了材料的表面性质. 测定了固定化肝素的量并研究了固定化肝素的稳定性. 结果表明固定化肝素量为2.34μg/cm-2,体外释放试验表明肝素量虽有下降但有较好的稳定性.  相似文献

EBF网络特征映射和恢复及其在鲁棒话者识别中的应用     

李昕  郑宇  江芳泽 《上海大学学报(英文版)》2002,6(4)

The performance of speaker verification systems is often compromised under real-world environments. For example, variations in handset characteristics could cause severe performance degradation. This paper presents a novel method to overcome this problem by using a non-linear handset mapper. Under this method, a mapper is constructed by training an elliptical basis function network using distorted speech features as inputs and the corresponding clean features as the desired outputs. During feature recuperation, clean features are recovered by feeding the distorted features to the feature mapper. The recovered features are then presented to a speaker model as if they were derived from clean speech. Experimental evaluations based on 258 speakers of the TIMIT and NTIMIT corpuses suggest that the feature mappers improve the verification performance remarkably.  相似文献
