Snort规则库的冲突检查

针对冲突是规则库不正确的一种表现形式,可能导致漏报和误报,对Snort规则库的冲突进行了研究.首先从一般意义上讨论了冲突的类型以及冲突检测的算法,给出了对Snort规则库的检查结果,最后分析了冲突的原因和可能的解决方法.     

实行厂务公开 维护企业和谐稳定

当前国有企业改革不断深化，职工的利益调整进一步加剧，计划经济时期积累下来的深层次矛盾逐渐显露，各种利益冲突集中凸现，企业职工信访案件明显增多，在一定程度上干扰了企业正常的生产工作秩序，影响和制约了国有企业的改革和发展。新时期新任务赋予了工会工作新思想和新内容，经过理论研究和实践探索，笔者就实行厂务公开，维护国有企业和谐稳定谈几点粗浅的认识。     

New Parallel Interference Cancellation Scheme for DS／CDMA Systems

This paper proposes a new multi-stage parallel interference cancellation scheme by modifying the conventional multi-stage parallel interference canceller (PIC). At each stage, it first converts the interference-cancelled outputs from previous stage into the a prior information, in terms of which the bit mean values are computed and the multi-access interferenee (MAI) for each user is evaluated, and then an interferenee cancellation is performed to obtain further interference suppression. To reduce the implementation complexity, wegive an approximation expression for bit mean value. The performance over AWGN channel is analyzed and compared to the conventional PIC. The user number K= 7 and spreading factor N= 13 are chosen as simulation parameters. The computer simulation results show that the proposed PIC has better performance than the conventional PIC both with 2 interference cancellation (IC) stages, at bit error rate of 10^-3 , for example, about 3 dB performance gain is obtained by using the proposed PIC. It is also shown that our proposed PIC with 1-stage is superior to the conventional PIC with 2-stage in performance, which is of practical value because PIC with fewer stages can bring about shorter processing delay.     

高等教育大众化背景下的新型师生关系

高等教育"大众化"打破了旧格局、旧体制,催生出发展高等教育的新思路,教育的主客体及其教学中介也体现出新的特点、产生新的价值冲突。传统的师生伦理受到挑战,良好的新型师生关系亟待建构。     

从合作到冲突--简析麦地那时期的阿拉伯-犹太关系

麦地那时期是伊斯兰教发展和阿拉伯国家初创的重要时期。当时已在阿拉伯半岛上相处近千年的阿拉伯和犹太两个民族的关系也经历了从合作到冲突的演变。造成这种演变的主要原因是双方政治经济实力的变化和各自需求的不同,也是伊斯兰教从初创到传播和阿拉伯民族从统一走向扩张的必然结果。犹太人也就成为阿拉伯人征服的第一个“异族”。

关系数据库系统移植中模式优化与冲突机制的设计

在深入研究异构数据库在模式和SQL语法等方面差异的基础上,设计了可扩展的冲突检查和处理机制,通过对潜在的冲突元素进行针对性调整避免模式冲突的不利影响.同时为了向上层应用程序屏蔽数据库移植中的模式调整,提出了在运行期间动态调整操作请求来保证数据库操作的准确性.     

Conflict analysis approaches for investigating attitudes and misperceptions in the War of 1812

Formal systems engineering approaches to modeling misperceptions and attitudes are employed within the framework of the graph model for conflict resolution to systematically study the War of 1812 between the United States of America and Great Britain in order to provide enhanced insights into the causes of the war. More specifically, relational definitions for preferences, movements and stability concepts are defined for describing the attitudes and associated behavior of decision makers involved in a conflict. To capture misperceptions of decision makers in the War of 1812, attitudes are studied within the structure of a hypergame. Combining attitudes and misperceptions within the paradigm of the graph model furnishes the flexible analytical tool which demonstrates that misunderstanding of attitudes by Great Britain and the United States may have contributed to the outbreak of this nasty war.     

跨性别文化交际中的面子冲突

面子是社会认知过程中形成的社会印象,是交际事件中交际参与者相互给予并相互协同的公共意象。本文从跨性别文化交际的角度讨论了引起面子冲突的原因及如何避免面子冲突,提出不同性别的交际规则、交际风格与策略乃至价值观等是引起面子冲突的原因;了解不同性别文化群体的交际规则,摆脱心理定势对跨性别文化交际的负面影响以及消除男女不平等的社会现象是避免跨性别文化交际的面子冲突的根本出路。     

企业税务策划与税收优惠政策研究

税收优惠无疑为企业等经济实体节约了成本费用,保留了收益,但并不是"免费的午餐",若不谨慎对待,则很可能要为此付出沉重的买单。基于这个认识,本文遵循理论研究与案例研究相结合的方法,对税收优惠冲突的根源进行分析,以期为税务策划实践活动提供有益的启示。
