In this paper, we investigate the problem of optimal road side units (RSUs) placement in Vehicular Ad Hoc Network (VANET) on a highway, which enables the VANET maintain a good connectivity. Our goal is to find out minimal number of road side units, such that the vehicles could communicate with RSUs. These road side units are connected by wire. We develop a randomized algorithm to deploy road side...
This paper investigates a multiple attribute decision making problem, whose attribute values are stochastic rough normal distribution. We define stochastic rough normal distribution variables, and then propose rules and stochastic rough normal distribution aggregation operator (SRN-WAA). The method based on SRN-WAA operator is proposed for the problem of the incomplete information on attribute's weights...
With the development of our economy and the strengthened foreign communication, logistics industry faces more and more intensive competition while having very rapidly development. It is necessary to build the public logistics information platform(PLIP) to meet forth stricter requirements for the instantaneity and accuracy of logistics information. But most Web-based systems are based on the original...
Cinnamomum camphor a tree is native to China, Formosa and Japan (Yoshida et al., 1969). The traditional oils are obtained from the wood and bark. As Camphor a essential oil has excellent antibacterial properties , studying camphor a oil could provide a theoretical basis for discovering and developing a new high-performance and low toxicity of antimicrobial agents. According to the results of this...
The compensation fuzzy neural network (CFNN) with fast learning algorithm and compensation fuzzy inference is proposed in this paper. And a new variable structure compensation fuzzy neural network (VS-CFNN) is proposed on the basic of CFNN. The fuzzy rules of the nodes are changed with the input nodes. The triangular function and parameter choosing methods have been given. At the mean time, the parameters...
The design problems of localization algorithm, distribution density estimation and node's moving path for data collection in multi-layers mobile wireless senor network are investigated. To ensure estimating accurately the node density, this paper proposes a new movement control strategy for fusion nodes based on probabilistic coverage model. This method completed the unknown node localization through...
Bohai Economic Zone is one of three major economic circles in China; it will reach 30% of the proportion of the country's total GDP until 2010, and plays an important role in China's economic development. But in recent years, its development shows a certain degree of fluctuate and non-equilibrium. So we apply the panel data DEA method to evaluate the economic benefits of the zone around Bohai in this...
Phase-locked technique is necessary for grid-connected converters to exchange power with grid. This paper presented a digital phase-locked loop (DPLL) algorithm based on phase adjusting at positive zero-crossing of every cycle. And then, an islanding detection method was proposed based on the DPLL into which a phase deviation was induced via modifying the phase-locked error. The results of simulations...
The economic cooperation of the Greater Mekong Sub-region (GMS for short) started in 1992. In its nearly 20-year operation process, GMS has constructed a multi-relational co-operation mechanism with the remarkable performance in social development, economic growth and people's living standards. In order to make GMS economic cooperation constantly deep-going and contribute to the merge, highly integration...
Since the launch of “Government Online Project”, China has been taking shape in its e-government field, while the e-government study, as well, manifests itself in features of multidisciplinary interaction, extensive range of study, profound scientific achievements and the like. Theoretical research of e-government could be traced back to the exploration of practical area and serves as the part-and-parcel...
Through researching the patterns and mechanism of life behavior of some animals, a knowledge processing system with biologic action feature was suggested by this paper, and the autonomic and creative features of the system were described. Following the thought of artificial life, the system was based on the rules and features that come from investigating the intelligent actives and behaviors of some...
