In this paper, we propose a system based on hypothesis that when we ask for help from others, 1) the closer people are, the more easy it is to get help, 2) the more simple things are easier to get help with. We carried out a survey to examine the hypothesis. The results show that this hypothesis is correct. Based on this hypothesis, we proposed a social networking service site based on a mobile environment...
The processing of data from the database using data mining algorithms need more special methods. In fact, some redundancy and irrelevant attributes reduce the performance of data mining, so the problem of feature subset selection becomes important in data mining domain. This paper presents a new algorithm which is called discrete binary differential evolution (BDE) algorithm to select the best feature...
Mapping the streets and street-crossings of the Nanjing city plan onto nodes and edges of a dual graph, we implement the traffic model of vehicles moving towards specified destinations with navigation and queuing. The navigation rules with local search within the next-nearst-neighborhood are applied both with and without dynamical feedback. The traffic is autonomously driven with a parameter which...
To overcome the bad performance of marine transformer fault diagnosis, which induced by the reliability of symptom and the correlation with each other. Based on improved D-S evidence theory, a novel marine transformer fault diagnosis method is proposed in this paper. Firstly, the fault diagnosis model is established based on traditional D-S evidence theory. Secondly, the effective measuring for the...
To improve assessment efficiency of construction project cost and enhance the development of electronic commerce for real estate, case-based reasoning (CBR) has been adopted by us. However, when a new cost assessment problem is input into the CBR system with the nearest neighbor method, there are usually little difference on similar degree for the retrieved most similar cases, thus, it is usually...
