SIP协议及其在网络中的应用

随着下一代互联网技术的不断发展,人们将不仅仅满足于将现有的PSTN(公共电话网)业务移植到IP网,而是需要电信运营商提供一个优秀的体系架构,将话音业务、视频业务、新兴的互联网业务整合到一个统一的框架中.SIP协议就是其中的关键纽带.     

Physical design method of MPSoC

Floorplan, clock network and power plan are crucial steps in deep sub-micron system-on-chip design. A novel di- agonal floorplan is integrated to enhance the data sharing between different cores in system-on-chip. Custom clock network con- taining hand-adjusted buffers and variable routing rules is constructed to realize balanced synchronization. Effective power plan considering both IR drop and electromigration achieves high utilization and maintains power integrity in our MediaSoC. Using such methods, deep sub-micron design challenges are managed under a fast prototyping methodology, which greatly shortens the design cycle.     

孙中山逝世后国民党中央权力结构运作与权力重心的转移

1925年3月,孙中山逝世以后,国民党中央权力结构重心遽失,权力斗争骤然加剧。结果,胡汉民“失却了把握中的国府主席”。中央权力结构重心遂由胡汉民移向汪精卫。8月,“廖案”以后,蒋介石在国民党内地位暴升,中央权力结构重心再由汪精卫移至蒋介石。蒋介石意外地成为中央权力重组的最大赢家。中常会成为新的党权核心。这是党权内争、党权与军权博弈之结果。

“This is the Whiteman’s Law”: Aboriginal resistance,bureaucratic change and the Census of Canada, 1830–2006

Census information of some form has been collected in Canada since the 1611 census of New France. Aboriginal people, identified or not, have been included in these enumerations. The collection of this information has had a profound impact on Aboriginal people and has been an element that has shaped their relationship with the dominant society. In response, Canadian Aboriginal people have often resisted and refused to co-operate with census takers and their masters. This article is an examination of this phenomenon focused on the censuses conducted in the post-Confederation period to the present. A census is made to collect information on populations and individuals that can then be used to configure and shape social and political relations between those being enumerated and the creators of the census. However, the human objects of the census are not just passive integers and they have resisted its creation in a number of ways, including being “missing” when the census is taken, refusing to answer the questions posed by enumerators or even driving them off Aboriginal territory. A census identifies elements of the social order and attempts to set them in their “proper” place and those who do not wish to be part of that order may refuse to take part. Archivists and historians must understand that the knowledge gained in a census is bound with the conditions of own creation. This has been noted by contemporary Aboriginal researchers who often state that the archival record of their people often distorts history and reflects the ideas and superficial observations of their Euro-Canadian creators. Changes to the Census of Canada since 1981, have increased the participation rate and therefore changed the nature of the record.

Mindset change in a cross-cultural context

Imagine you are Thai and a member of a management team from a European company that acts in an Asian emerging market. Imagine you are a European expat with the assignment to double the turnover from that Asian company in a few years. Imagine you are a Change Maker and they ask you to facilitate the (multinational) management team of that Asian company to develop a market strategy and translate it into a business plan, and you have to deal with cultural differences. How do you manage a small-scale change process based on the principles of action learning in that specific multinational context? That's the essence of this account of practice.
