With the emerging vehicular network and the possible diverse applications, Intelligent Transportation Systems (ITS) have been evolving to Cooperative ITS (C-ITS, CITS) with connected intelligent vehicles, and the topics in this domain also raise more and more research interesting recently. However, subjecting to the immaturity of V2X communication technology and the deployment of intelligent vehicles...
According to the group, interactive and real-time characteristics of mobile social environment, a novel user behavior prediction algorithm in mobile social environment is proposed in this paper. In this algorithm, firstly, a coding based two-dimensional Apriori method is presented to analyze user service behaviors: on one hand, the correlation analysis of a user behavior history is performed; on the...
Owing to the complexity of the photovoltaic system structure and their environment, especially under the partial shadows environment, the output characteristics of photovoltaic arrays are greatly affected. Under the partial shadows environment, power-voltage (P-V) characteristics curve is of multi-peak. This makes that it is a difficult task to track the actual maximum power point. In addition, most...
In past ten years, Changqing Oilfield Company had constructed many information systems, mess of data had been collected in database. A great deal of knowledge and experience was embedded in these databases. To get the useful information, we must assure that all the data in the database are accurate, integrated, consistent and unique, so cleaning data of errors in structure and content is very important...
Based on the analysis of the traditional bubble sort algorithm, this paper proposes two bidirectional bubble sort algorithm design ideas. After giving C language description of the three algorithms, the paper tests the new algorithms, analyzes comparatively the time complexity and space complexity of the three algorithms, and summarizes such a conclusion that the first new algorithm has the same average...
