In recent researches, wind speed model of single wind farm has been used to study the traditional wind farms modeling, ignoring the correlation between series of multiple wind speeds. Based on Copula function and ARMA model, a dependent model for multivariate wind speed series is proposed. Firstly, Copula multivariate distribution model is used to capture spatial dependencies, and then ARMA model...
Blind people need guide tools to help them walk safely. The traditional guide tool is a guide rod. However, the guide rods always have shortages. With the development of technology, the electronic guide instrument for blind people has been designed. In this paper, infrared sensors are used to detect road information, and the information is analyzed by recognition algorithm. Then the electronic device...
In this paper, the event-driven control strategies have been proposed to study the consensus of fractional-order multi-agent systems. A general consensus control algorithm is introduced to analyze the fractional-order agent dynamics. Base on limited resources of embedded microprocessors and wireless sensors, event-triggered control mechanism have been exploited in a centralized approach, where all...
Urban road congestion is increasingly serious, in order to optimize the traffic situation, and improve the efficiency of vehicles, so as to provide service for traveling user. Then analysis four major systems, namely the bus electronic station board system, evaluation system of urban road traffic state, urban traffic guidance system and website demonstration system. Regarding average travel speed,...
This paper considers the second-order consensus problem of discrete-time multi-agent systems over fixed and undirected network topologies. A distributed consensus protocol utilizing the current and one-step delayed position information is proposed. It is interesting to found that second-order consensus in such a discrete-time multi-agent system cannot be ensured without any one-step delayed position...
This research measures the perceived international risk and their inclination to corresponding marketing countermeasures, and summarizes ten kinds of international risks correlated with marketing tactics and then it utilizes cluster analysis to explore the inclination to different marketing tactics when administrative staff confront different perceived risks.
Coordination based on Multi-Agent constitutes a focus of open, distributed, complicated systems. In this paper,this technique is applied to urban intersection traffic coordination control. The design employs an Agent controller for each signalized intersection that coordinates with neighboring Agents. The coordination mechanism of traffic signal control Agent is analyzed. The abstract dynamic model...
Parabolic Radon transform (PRT) is one of the most effective methods to eliminate multiple. Based on model study and programming, the article shows the physical signification of FPRT firstly, then presents the theories and implementation processes about the forward and inverse parabolic Radon transform infrequency domain. It also discusses the aliasing in radon domain, the stability of radon transform,...
