RFID is being gradually adopted and deployed in a wide area of applications and it generates massive RFID data. The purpose of the RFID event processing is to extract valuable information from the real-time and large volume RFID data. In this paper, we divide RFID event into RFID Simple Event and RFID Complex Event and apply different algorithms to process them because of their different characteristics...
Traditional comprehensive evaluation methods have the problem of inconsistence between multi-evaluation conclusions. To solve the above problem, some researchers provide a multi-evaluation conclusion aggregation method based on singular value decomposition. However, due to the approximate process on ordinal matrix, the SVD-based aggregation method will lose the ordinal information of original matrix...
Collaborative filtering is the most successful and widely used recommendation algorithm in E-commerce recommender systems currently. However, it faces severe challenge of cold-start problem. To solve the new item problem in cold-start, a cold-start recommendation method based on dynamic browsing tree model is proposed. Firstly, user browsing records are transformed to dynamic browsing tree (DBT) based...
As a new kind of identity authentication technology, finger-vein recognition has many merits. In order to improve the robustness and stability of detecting the finger-vein, an enhanced method for extracting finger-vein feature based on morphology is proposed in this paper, which combines with morphological peak and valley detection. The images will be scanned across the boundaries and the valley detection...
Arundo donax root was used to prepare activated carbon by H3PO4 activation for the removal of methyl violet (MV). The activated carbon has a micro-mesoporous structure with BET surface area 1392 m2/g. Pseudo-second-order model could predict the adsorption kinetics for the entire process. The sorption involved several stages and the actual rate controlling step was film diffusion for the whole process...
With the development of digital and waveform micro-seismic emission (ME) technology, it makes the recognition of ME source possible. Because of the noise and complex of ME signal transmission characteristic, the recognition of ME source is very difficult. In order to resolve this problem, the new method of multi-sensor data fusion on decision level was presented. Using the data from each sensor in...
