The current television model is undergoing a deep-rooted change, and its future depends, to a large extent, on its presence in cyberspace. For the purposes of this study, we selected the internet homepages of the 12 regional radio-television stations which together make up the Spanish Federation of Regional Radio and Television Organizations （FORTA）. The aim was to carry out a research project using content analysis techniques.展开更多

In this paper, a C60-based clustering algorithm is proposed for the specific planned network of space tracking and surveillance system(STSS), where all the sensors are partitioned into 12 clusters according to the C60(or football surface) architecture, and then a hierarchical sensor-management scheme is well designed.Finally, the algorithm is applied to a typical STSS constellation,and the simulation results show that the proposed method has better target-tracking performance than the nonclustering scheduling method.展开更多
