英汉词语空缺与跨文化差异及翻译策略探究

语言是文化的载体,文化上的差异导致了英汉语言中的词汇空缺现象,词汇空缺现象反映了语言的民族性。在跨文化交际中,词汇空缺会给交际带来障碍,造成语用失误,甚至导致交际失败,论文就词语的空缺现象与跨文化差异中的翻译策略进行了一些探讨。     

网格计算环境中的安全信任协商系统

网格技术促进了广域网络环境下的资源共享和协同工作.然而,在网格环境中,服务的提供方和请求方往往位于不同的安全域,如何为位于不同安全区域的陌生主体间动态地建立信任关系成为一项应用难题.基于信任管理基础设施,通过协作主体间信任证、访问控制策略的交互披露逐渐为各方建立信任关系,设计并实现了一个保护协商方隐私信息的安全信任协商系统.该系统采用一种基于属性的委托授权信任证、访问控制策略及一致性验证算法,实现策略的动态调整,从而生成满足访问控制策略的所有最小可满足信任证集,能够使理论上存在的信任关系得以自动建立.通过在CROWN平台中的应用,显示该系统能够满足网格应用中信任自动建立和敏感信息保护的需求.      

东航发展战略及对策建议

1997年东航在组织结构和经营机制等方面发生了根本性的变化：东航集团公司与东航股份公司进行了机构分立、东航股份公司股票在海外上市取得成功并即将发行A股，这标志着东航从此进入了一个新的发展阶段。本文在分析东航集团所面临的经营环境和自身条件的基础上，提出东航的若干战略发展思路以及所应采取的对策建议。一、东航面临环境：充满发展机遇、面临严峻挑战上海区域经济近几年的蓬勃发展，不仅使L海及其临近城市成为我国航空运输需求量增长最快的市场，为东航集团航空运输主业的发展提供了良好的发展机遇，而且也为东航集团其他行业…

Research of multi-path routing based on network coding in space information networks

A multi-path routing algorithm based on network coding is proposed for combating long propagation delay and high bit error rate of space information networks. On the basis of traditional multi-path routing, the algorithm uses a random linear network coding strategy to code data pack- ets. Code number is determined by the next hop link status and the number of current received packets sent by the upstream node together. The algorithm improves retransmission and cache mechanisms through using redundancy caused by network coding. Meanwhile, the algorithm also adopts the flow distribution strategy based on time delay to balance network load. Simulation results show that the proposed routing algorithm can effectively improve packet delivery rate, reduce packet delay, and enhance network performance.     

Configurationmodelofpartial repairablesparesunder batch ordering policy based on inventory state

Rational planning of spares configuration project is an effective approach to improve equipment availability as well as reduce life cycle cost （LCC）. With an analysis of various impacts on support system, the spares demand rate forecast model is constructed. According to systemic analysis method, spares support effectiveness evaluation indicators system is built, and then, initial spares configuration and optimization method is researched. To the issue of discarding and con-sumption for incomplete repairable items, its expected backorders function is approximated by Laplace demand distribution. Combining the （s-1, s） and （R, Q） inventory policy, the spares resup-ply model is established under the batch ordering policy based on inventory state, and the optimi-zation analysis flow for spares configuration is proposed. Through application on shipborne equipment spares configuration, the given scenarios are analyzed under two constraint targets：one is the support effectiveness, and the other is the spares cost. Analysis reveals that the result is consistent with practical regulation;therefore, the model＇s correctness, method＇s validity as well as optimization project＇s rationality are proved to a certain extent.     

Rescheduling of observing spacecraft using fuzzy neural network and ant colony algorithm

This paper aims at rescheduling of observing spacecraft imaging plans under uncertainties. Firstly, uncertainties in spacecraft observation scheduling are analyzed. Then, considering the uncertainties with fuzzy features, this paper proposes a fuzzy neural network and a hybrid rescheduling policy to deal with them. It then establishes a mathematical model and manages to solve the rescheduling problem by proposing an ant colony algorithm, which introduces an adaptive control mechanism and takes advantage of the information in an existing schedule. Finally, the above method is applied to solve the rescheduling problem of a certain type of earth-observing satellite. The computation of the example shows that the approach is feasible and effective in dealing with uncertainties in spacecraft observation scheduling. The approach designed here can be useful in solving the problem that the original schedule is contaminated by disturbances.
