2006年的8月正值暑期电影黄金周，几乎全球的电影市场和往年都一样，被高成本制作的精美的好莱坞大片所垄断。这样毫无悬念的境况，在另一方面多少使得一些其实相当有水准的低成本制作电影，相形之下显得有些黯然失色。以眼光刁钻著称...2006年的8月正值暑期电影黄金周，几乎全球的电影市场和往年都一样，被高成本制作的精美的好莱坞大片所垄断。这样毫无悬念的境况，在另一方面多少使得一些其实相当有水准的低成本制作电影，相形之下显得有些黯然失色。以眼光刁钻著称的德国制片人伯恩·伊钦格投拍的影片《香水：一个凶手的故事》（Perfume——The story of a murderer）无疑就是其中之一。展开更多

This paper also analyzes the launch strategies for small satellites such as piggyback, networking launch, and single launch with a small launch vehicle(SLV). Finally, the development trend of reusable launch vehicles is discussed as well as the development prospects for China's reusable launch vehicle.展开更多

Hence, it is conventional that users in a digital community network take part in a collaborative mechanism for the purpose of service selection. The participation usually brings unnecessary burdens for users, such as giving opinions, storing service information. Extra communication overhead hinders the performance of the network. Thus, the community administrators are facing a problem of how to obtain an overall service selection result for the whole community readily and effectively. To address this problem, we present a k-median facility location agent model. The model analyzes the procedure of service selection through five entities and six types of messages. Two algorithms are elaborated in pursuit of a global optimization concerning connection costs between users and facilities where services are deployed. To evaluate our model, we conduct extensive simulations and present a detailed analysis of the simulation results.展开更多
