In recent years, the evolution of online social networks has become an important research topic in online social network analysis. An important approach to this problem is to detect community evolution events so as to understand the evolution of the whole network. Considering the huge amount of data in large social networks, an efficient and scalable community evolution detection algorithm is necessary...
With the development of 3D audio, distance rendering in multi-channel spatial audio becomes a hot topic of great interest. In this paper, the directional-to-diffuse energy ratio (DDR), a novel relative distance cue, is presented based on Fast Independent Components Analysis (FastICA). DDR is used to trace the relative distance of recreated sound image, by extracting the energy ratio of the directional...
In this paper, We applied CCI canceller to remove multiple access interference in co-channel environment and improved performance of Impulse Radio UWB system. Also, we have evaluated the performance of UWB system with Truncated Type-II Hybrid ARQ scheme for achieving high quality data transmission.
With the development of data collection technology, effective visualization tools are needed urgently to understand the abundant multidimensional and multivariate data and information in the science, engineering and commerce fields. Star Coordinates is a traditional multivariate data visualization technique, but there are some limitations of it. In the paper we propose the advanced star coordinates...
With the heavily increase of information cognitive burden, it is urgent for us to find effective visualization tools to grasp the abundant multidimensional and multivariate information in the science, engineering and commerce fields. Star coordinates is a traditional multivariate data visualization technique, with some limitations, e.g. the loss of information, the poor result of visualization and...
