In this paper, the maximum flux principle (MFP) is proposed to describe complex interactions among agents in ecosystem which usually tend to generate intricate patterns under specific environmental constraints. Accordingly, we introduce a new simulation method based on Neural Network to reveal the dynamic mechanisms of ecosystem evolution. The new simulation method may provide important implications...
This paper regarded indoor environment and decorative lumbers as the research object, and presented an integrated rule on the measure level of the overall recognition rate of the sample based on BP neural network classifier by trying to recognize the position of maximum value of vectors W to identify the categories of the samples. The number of networks could be delimited with the highest prior recognition...
This paper presents a variant of Particle Swarm Optimization, called Subpopulations Shuffled Dynamic of Particle Swarm Optimization (SSDPSO). In SSDPSO, particles are partitioned into different subpopulations by fitness to maintain diversity of population efficiency. The subpopulations will be shuffled together to be a new population after they evolved for certain iterations. Furthermore, the iterations...
This paper further studies the exponential stability of delayed bidirectional associative memory neural networks and focuses on the impulse effect on the exponential stability property. It is shown that if the corresponding impulse-free DBAM is globally exponentially stable the impulsive analog will remain its stability property even if the measurements of the states are magnified to some extent at...
This paper proposes an improved PSO (particle swarm optimizer) named as BDPSO (behavior-distance PSO). In BDPSO particle changes fly behaviors guided by the optimum of each particle and the optimum found by the whole particles. In this scheme, individuals can adapt themselves more suitable to search for the destination. Some benchmark functions are tested for comparison the performance between BDPSO...
In both industry and research domain, the consensus is that alarm in advance is more valuable than informing after pipeline having been destroyed, and a long-distance monitoring system is more valuable than one with a shorter distance. However, systems reported so far can hardly achieve the requirement. In this paper, we propose a general long-distance (ges50 Km) monitoring system based on distributed...
Electric discharge machining (EDM) is one of the most accurate manufacturing processes available, and it is quite indispensable to aerospace industries. Powder mixed EDM (PMEDM) is a new process through which a better surface can be reached, nevertheless, PMEDM is a complicated and random process influenced by many parameters, and the intricacies of mechanism hinders its application. This paper presents...
