Formation Mechanism of the Cluster Space of Wuhan Metropolitan Area amid Evolution of Power Relationship

作者： Gao Ying ye jianwei The 713th Research Institute of China Shipbuilding Industry Corpration

Aiming at the problem of zero sequence circulation control of parallel inverters,a zero sequence circulation control method is proposed by using 111 and 000 two zero vectors in the process of re distribution of SVPWM *** method can effectively reduce the zero sequence circulation,which makes the current loop control to the two inverter bridges,and the zero sequence current loop control is carried out respectively,which makes the two inverters to play the role of half of the zero sequence circulation *** method does not increase the complexity and cost of the system,and it is not necessary to adjust the control strategy in parallel with the multi group ***,the effectiveness and superiority of the proposed method are verified by simulation and experiment.

China City Planning Review 2013年第2期22卷 6-14页

作者： Yan FENG jianwei ye Yaping HUANG Caige Li Huangzhong University of Science and Technology School of Art Designand MediaEast China University of Science and Technology College of Architecture and Urban Planning Tongji University Academic Committee of Urban Planning Society of China Architecture and Urban Planning School Huazhong University of Science and Technology

With the urban regionalization and regional urbanization, the spatial structure of cluster appears in some metropolitan areas, among which Wuhan can be taken as a typical case. This paper analyzes the formation of Wuhan metropolitan cluster space from the perspective of power relationship. A "twin-city" approach is developed in the peripheral area of Wuhan caused by the game between local governments at different levels. With the equal development opportunities in all directions and the alliances between different district governments and capital, the balancedly embedded cluster space is formed in Wuhan metropolitan area. And if there are no huge internal and external changes, the cluster space in Wuhan will continue to develop.

随着云计算这种新的网络计算模式的普及,云用户信息隐私性保护问题成为云计算领域亟待解决的重要问题。当用户将数据上传到云服务器端,用户就不再能保证其数据受到保护。为了让用户对上传到云上的数据进行自主的授权和控制,提出一种基于分布式信息流控制的访问控制方法 DIFC-AC,其核心思想是采用安全标签来跟踪数据的流动,数据所有者通过在标签中设置授权条件来控制进程对该数据的访问权限。提出DIFC-AC原型系统的设计与实现,DIFC-AC保证用户数据在服务器端的整个生命周期的隐私性。性能测试数据显示DIFC-AC原型系统的性能开销能够控制在合理范围之内。

基于Jarecki和Shmatikov的带承诺加密电路技术和Pedersen的可验证门限秘密共享方案,提出了一种新的适用于恶意环境的移动代码保护协议.新协议使用一组服务器来代理部分零知识证明过程并共享密钥.当诚实的服务器多于2?3时,新协议:1)能同时保护输入输出的安全,较现有协议有更高安全性;2)适用于无交互的移动代码环境;3)使得发起者无需和执行者交互就能验证移动代码的正确性,从而避免恶意发起者使用恶意代码来破坏执行者的安全性;4)使得发起者和执行者能公平地得到正确的输出.
