Based on dynamic research perspectives of time slicing, this paper shows an endeavor on mining dynamic features of the scientific teams. Traditionally the static method of network structure analysis can successfully be used to analyze the distribution of network resource structure. But it cannot be used to explore the dynamic features of research groups, because of its lacks on the influence of some...
With the social network being widely used, people would like to use the friends recommendation provided by a social websites. There are lots of methods to make the recommendation results more accurately and efficiently. By considering the feature selection strategy in the stage of data preprocessing, we propose a novel friend recommendation system using a classification model, which formulates the...
According to the algorithms based on Gaussian assumption are not accurate due to the presence of non-Gaussian signals and noise in the real environment. In this paper, a non-Gaussian noise model based on alpha stable distribution is set, and a time-delay estimation algorithm based on fractional lower order statistics is studied, where fractional lower order covariance matrix makes the time-delay estimation...
Based on the Technology Acceptance Model (TAM) developed from the theory of reasoned action (TRA) and social psychology research by Davis (1989), this study models the use of the Internet-based modular object-oriented dynamic learning environment (Moodle) by students of the computer science department at Ming Chuan University (MCU), Taiwan. Apart from student demographics and background information...
According to practical requirement, this paper puts forward an alarm event correlation approach basing on event driving, which considers the temporal relationship between events, and establishes several Petri net models. The experiment results show that, the approach basing on event driving to select time window can implement the alarm event correlation correctively and effectively for complex network...
Beijing and Xianghe sites are selected as study area. MODIS/Terra C005 aerosol product of the whole 2005 year is validated by matching the MODIS product and AERONET within plusmn30 min of MODIS/Terra overpass times considering the aerosol movement velocity of given sites, then to analyze their applicability. The results show that MODIS C005 aerosol product overestimates the real value greatly at Beijing...
