In virtue of its widespread application scenarios, especially in battlefield communication, disaster rescue, satellite and deep-space transmission, Delay-disruption Tolerant Network (hereinafter referred to as DTN) has become one of the most attractive focuses in research for future Internet. Due to the intermittent connectivity, mobility of nodes, signal interference, jamming in DTN, there exist...
This research studies users' adoption process of WiMAX. This process cannot be viewed in isolation and must consider the effect of co-existing telecommunication networks and a highly saturated market. WiMAX success would involve getting existing mobile subscribers to switch over to WiMAX. Hence, 2/2.5G and 3G subscribers are used separately as subjects of investigation because they are likely to form...
Video annotation is very important for video management, such as video retrieval. Despite continuous efforts in inventing new annotation algorithms, the annotation performance is usually unsatisfactory, and the annotation vocabulary is still limited due to the use of a small scale training set. In this paper, a novel video annotation framework based on the video object is presented, named object-based...
Automatic image annotation is very important for image retrieval. Despite continuous efforts in inventing new annotation algorithms, the annotation performance is usually unsatisfactory, and the annotation vocabulary is still limited due to the use of a small scale training set. In this paper, a novel image automatic annotation system based on the WordNet is presented, named WordNet-based image annotation...
