一种基于MTS的网络区域管理工作站实现策略

网络扩容的一个重要障碍是异构子网连接后的互连管理问题。分区域的一体化管理无疑是一种解决办法。本文提出一种基于管理协议细栈(MTS)来构造一体化的区域管理中心(RMC)的策略,这里的 RMC 可实现彼此间的管理通信和互操作,从而也解决了扩容后的互连管理问题。结合正在进行的工程实践,文章还进一步从技术角度上讨论了实现策略。

Directional change‐point detection for process control with multivariate categorical data

Most modern processes involve multiple quality characteristics that are all measured on attribute levels, and their overall quality is determined by these characteristics simultaneously. The characteristic factors usually correlate with each other, making multivariate categorical control techniques a must. We study Phase I analysis of multivariate categorical processes (MCPs) to identify the presence of change‐points in the reference dataset. A directional change‐point detection method based on log‐linear models is proposed. The method exploits directional shift information and integrates MCPs into the unified framework of multivariate binomial and multivariate multinomial distributions. A diagnostic scheme for identifying the change‐point location and the shift direction is also suggested. Numerical simulations are conducted to demonstrate the detection effectiveness and the diagnostic accuracy.© 2013 Wiley Periodicals, Inc. Naval Research Logistics, 2013     

REFLECTIONS ON THE INTEGRATION OF THE MILITARY IN SOUTH AFRICA

This paper explores the contribution of the African Union (AU) to human security promotion in Africa. It contends that human security concerns informed the formation of the AU. Through the efforts of the AU Commission, the African ruling elite and policy-makers have become aware of human security doctrines. Human security ideas have been integrated into AU binding agreements, declarations, decisions and policies. The commission is now in the difficult, yet most important, phase of trying to persuade significant numbers of the African ruling elite and civil society to accept human security as a guiding principle and the desirable norm. Through the African Citizens' Directorate (CIDO), the commission is using indigenous African civil society groups to institutionalise human security doctrines in Africa. The commission faces serious challenges in its efforts to make human security the only security norm. While member states of the AU that have never been comfortable with the introduction of human security doctrines into the continental integration project are tacitly undermining the CIDO's ability to work with civil society groups to institutionalise the doctrines in Africa, the leaders who enthusiastically supported the integration of human security doctrines into the documents and work of the AU have seemed in recent times to be less resolute in their support of AU Commission's human security work.
