The Automatic Identification System (AIS) is an automatic tracking system which has been widely applied in the fields of intelligent transportation systems, e.g., collision avoidance, navigation, maritime supervision and management. Compare with other positioning systems, e.g., very high frequency (VHF) and radar, AIS can conquer the human errors and it is almost not affected by the external environment...
Emotion is an important indicator of depressive conditions. Emotion recognition based on physiological signals such as electroencephalogram (EEG) and functional near-infrared spectroscopy (fNIRS) has gained significant attraction in healthcare domain research. Sharing of physiological signal data related to emotional response between different healthcare systems has the potential to benefit both laboratory-based...
This paper attempts to introduce the concept of cloud computing into simulation and proposes a multi-user collaborating simulation mechanism based on cloud computing. This mechanism is different from the ideology of integrating (with the same language, on the same platform, etc), and embodies the ideology of distributing and collaborating. The mechanism can be implemented in one of the many cloud...
According to the statistical data of R&D input-intensity from 1995 to 2007 in Shanghai, the paper forecasts the medium-term and long-term R&D input-intensity in Shanghai based on a kind of improving form of grey forecasting model GM(1,1), that is DGM(1,1) model. The calculation results show that DGM (1, 1) model has some advantages, so as higher predicting precision, the better fitting with...
The various applications of polarimetric SAR data have brought to the fore questions of polarimetric calibration. Most polarimetric calibration methods based on distributed targets employed reflection symmetry assumption, which might be inconsistent with the truth due to a possible orientation angle shift, and therefore would skew the polarimetric signatures of targets. In this paper, a model incorporating...
Expressway transportation is playing a more important roll in economic construction and social life. The expressway network status, including section flow and average speed, is important to the expressway management for analysis and decision making. Traditional ways of monitoring the road is using detectors which cost much to install and maintain. We propose speed constraint deducing model and similarity...
The project-based organizations engaging in engineering consultancy are at the early stage in China. For the manager of China, how to conduct the organization design for them according to contextuality that characterizes the conditions of China is an important issue. First, the factors that affect the performance of this type of the project-based organization of China are analyzed. Then, the organizational...
With the number increment of mobile computing equipment, the invalidation of equipment and broadcasting information because of wireless bandwidth, communication quality and too long scheduling queue that badly influence the system computing performance. Mobile cache is a good technology to solute this difficult problem. Considering the priority problem of broadcasting queue generated by data invalidation...
