GIS geoprocessing service is the inevitable result of the combination of Geographical Information System and Web service technology, which is widely used for the interoperating of geoprocessing operations in distributed platform-independent and language-independent environments. Since function limited single GIS geoprocessing service cannot satisfy the demands of internet users anymore, it is necessary...
Based on particle swarm optimization (PSO) algorithm for optimal design of PID controller, a method is proposed to navigate of a two-wheeled mobile robot from a given initial configuration to a desired final configuration in an unknown environment filled with obstacles. The mobile robot can follow a wall with PID control to adjust motor speed and avoid obstacles with moving square method in an unknown...
Supervised classification of fully polarimetric SAR image using neural network is a common method nowadays. As an effective learning method of neural network, BP algorithm is the most widespread one in the neural network algorithms. However, BP network is easy to fall into local extremum and exists shortcomings such as the slow training process. To this end, this paper presents a method of supervised...
A fundamental theorem in the drift analysis of EAs was initially presented in Jun He and Xin Yao's paper(Artificial Intelligence 127(1) (2001) 57-85). However, the theorem remained defective in spite of its successful applications in some specific cases. This paper points out those defects, then suggests some modifications on the theorem and introduces a new and rigorous proof. This work is expected...
Based on the type analysis of manufacturing network alliance, this paper proposes that the manufacturing enterprise network alliance has a reasonable radius for cooperation production, and this is quite different from other kinds of alliance or mixed enterprise network alliance. When the reasonable radius is beyond the threshold, the partners' contribution to the alliance cooperation production will...
