摘要：Hazard prevention in mission plans requires careful analysis and appropriate tools to support the design of preventive and/or corrective *** is most challenging in systems with large sets of states and complex state *** the case of sociotechnical systems,hazard prevention becomes even more dicult given that the behaviour of human centric components can at best be partially *** the present article we focus on a specic class of sociotechnical systems-namely air spaces containing pilot controlled as well as autonomous aircrafts and introduce the notion of relevant *** also introduce soft institutions as an appropriate basis for analysis,with the aim of addressing relevant *** concept of soft institutions is drawn from specication languages for interaction between agents in multi-agent systems but,in our case,is adapted for use in systems that combine human and automated actors.

摘要：前言随着高速和极高速ADC以及数字处理产品的不断涌现,正使得过采样方法成为宽带和射频系统的实用架构方法。尤其是,半导体技术进步为提升速度以及降低成本做出了诸多贡献（比如价格、功耗和电路板面积）,让系统设计人员得以探索转换和处理信号的各种方法——无论使用具有平坦噪声频谱密度的宽带转换器,或是使用在目标频段内具有高动态范围的带限Σ-Δ型转换器。这些技术改变了设计工程师对信号处理的认识,以及他们定义产品规格的方式。

摘要：详细描述了同步数字系列(SDH)网络保护结构的类型和特点,并介绍了一种测试SDH网络保护性能的快速、可靠的方法。

摘要：酋长皇宫酒店隶属于Kempinski旅店鞋号，并且被认为是世界上最大、最豪华的酒店之一。2005年2月酒店铺开了红地毯，欢迎客人入住。由于“五星级”显得远远不足以标榜这个华贵的处所，干脆就将“皇宫”一词冠在酒店名前。客人被带入一个不可思议的世界，那里洋溢着浪漫、妙想与奇遇，浸淫在国王般的奢华中。奢华常与黄金相伴，特别是在阿拉伯世界中。伦敦的DHA做的照明设计更为其平添了一份魅力。
