Spatial Join Aggregation (SJA) is a time-consuming operation in the spatial database, how to design efficient distributed SJA algorithms is attracting more and more attention. The paper proposed a stratedgy (RSJA-MR) to process spatial join aggregation in MapReduce based on distributed R-tree, which is used to return results of SJA more efficiently. SJA tasks met independent parallel computation and...
With the fast development of electric vehicle (EV), the charging and coordination strategy of the prospective electric vehicles can be possibly based on regional hierarchical control technology. The paper describes the land decision method to obtain the spatial load of EV in a region, including industrial, commercial and residential area. Based on the forecasted spatial load of EV in the region, the...
With the development of the technology and economic, the video supervising equipment are widely used in commercial, private areas and public management. It is innovative of the paper to make full use of the video images to estimation the crowd density and defend risks of stampedes. According to connect data in different crowds, this paper proposes a method that is based on the Gaussian Background...
This paper is intended to investigate a variable series-series (SS) compensation network of the loosely coupled transformer (LCT) in the inductive power transfer (IPT) system. With the proposed compensation network, an additional switch is used to facilitate the transition from the LC resonance condition to three order T-type resonance condition with the same operating frequency to achieve constant...
Driving when tired is one of the main reasons that accidents happen. So far, many preventive measures have been taken. However, the effect is not satisfying. Accidents result from tired driving still happen from time to time. By observing and analyzing the work process of drivers, this paper proposes a fatigue detecting scheme of drivers based on Electroencephalograph(EEG). Using ThinkGear brain-wave...
In the process of cargo handling in bulk port, dynamic weighing of cargo is the basis of the information management system for bulk cargo handling. Due to many interference factors, it is difficult to obtain the actual lifting weight of portal crane by using mechanical way. To address this issue, a new method of using motor power is proposed in this paper. In this method, the real-time motor voltage,...
This paper investigates the problem of the extended dissipativity analysis for discrete-time Markov jump neural networks with finite piecewise homogeneous Markov chain and mixed time delays. By introducing a triple-summable term in Lyapunov function, the reciprocally convex approach is utilized to bound the forward difference of the triple-summable term and then the extended dissipativity criterion...
A control system which can analog the external input and output characteristics of the diesel engine is aimed to be designed in this paper. Proposed a scheme that using the method named "Adaptive neural network based on model reference" to control asynchronous motor in order to simulate the external characteristics of the diesel engine. The simulation model of diesel engines, asynchronous...
The tracking system of robot was optimized by using the fuzzy BP neural network PID control algorithm in this paper, which was based on the traditional PID control algorithm. The control algorithm combines the functions of fuzzy control, the neural network control and the traditional PID control algorithm, which resulted The PID control has the ability of logical reasoning and computing. The system...
