Privacy preserving data mining has become an important research problem. The chief research is how to mine the potential knowledge and not to reveal the sensitive data. In reality, large amounts of data are stored in distributed sites, so the DPPDM (Distributed Privacy Preserving Data Mining) is very important. This paper gave a survey on the DPPDM. Based on different underlying technologies, there...
ICE(Intercultural Collaboration Environment) is a joint research project which is dedicated to overcoming language barriers and cultural differences, serious communication problems. But the translation tools at present are poor and the users can't understand each other very well. In order to improve mutual comprehension between users, we propose the ontology-based ICE integrating ontology, agents...
Computer Interface Technology is a specialty course about the hardware. The current teaching situation of the undergraduate is analyzed, and the factors that impact teaching quality are pointed out. Then some solutions are given to improve teaching quality.
In this paper, we use a decision analysis method that respects to linguistic multiple attribute decision-making problems with partial information of attribute weights to solve the main problem in the bidding stage of E-government project surveillance and evaluation. We have established an evaluation model through ideal point and triangular fuzzy number. Linguistic assessment information is transformed...
This paper discusses a new e-learning method which use thematic learning to make knowledge integrated into a whole and use blended learning mode to improve the feasibility of thematic learning and make e-learning surrounded with a meaningful environment. At first, the definition and the model of theme-based blended e-learning are proposed. The model shows how the two learning mode are linked in the...
How to allocate the profits from cooperative purchasing is a key factor to the formation and maintaining of aconsortium. In this paper, according to the characteristics of joint procurement. Established a cooperative game model-Union game model o Analysised several methods based on cooperative game theory of the distribution of benefits. According to the model of Heijboer and Fredo Schotanus. Explored...
This paper presents a new algorithm for detecting the human's reciprocating motion in pornographic videos. First, the motion vector is extracted from mpeg video stream and pretreated so that the motion features are extracted by analyzing the motion rule of the objectionable videos. Then the whole videos are detected through setting a threshold. Experimental results demonstrate that the correct recognition...
Drugs tender procurement is a complementary policy of Chinese Health Care Reform, which has been promulgated and implemented since 2000 in China, and has achieved good results. Bidding-evaluation and Bidding-decision are often accepted as the key points in the bidding process. A successful bidding is directly caused by a scientific bidding-evaluation system. This paper mainly focuses on the system...
The localization technology is very important in wireless sensor network. Many localization algorithms have been proposed in recent year, in which DV-Hop is the prevail localization algorithm. But the DV-Hop algorithm is not very accurate. In this paper, we propose an algorithm to improve the positioning accuracy. The proposed algorithm mainly bases on the radio range of anchor nodes to determine...
In order to gain a better understanding of land application of sewage sludge, we studied the effects of sewage sludge compost on the tall fescue and the marigold compared with the control group (Shanghai tidal bank soil) in greenhouse experiment. The mixed proportion of the sludge compost in the Shanghai tidal bank soil was controlled respectively in 0%, 5%, 10% and 20%. The plants grown on the compost-amended...
