—The gradual introduction of advanced ATM procedures such as Continuous Descent Approaches (CDA) creates a challenge when balancing the capacity-demand of arrival traffic in the presence of constrained ground (runway, taxiway, gate) resources. Part of the challenge is to understand the interdependency between spatial-temporal distribution of arrival traffic(More)
—To comprehensively understand the characteristics of gas nanosensor between temperature and sensitivity, this paper has developed a Backward Propagation (BP) neural network based on Particle Swarm Optimization (PSO), which is applied to fitting the temperature-sensitivity characteristic of the S n O 2 gas nanosensor mixed with benzene. The simulation(More)
Adaptive inertia weight is proposed to rationally balance the global exploration and local exploitation abilities for particle swarm optimization. This paper describes an adaptive strategy for tuning the inertia weight parameter of the PSO algorithm - Exponential type adaptive inertia weighted Particle Swarm Optimization (EPSO). This adaptive tuning(More)
Dynamic optimization of electromechanical coupling system is a multi-subject problem on mechanics theory. The optimization of such kind problem is studied. Particle swarm optimization (PSO) is introduced. In order to resolve the insufficiency, a new kind of adaptive leap particle swarm optimization (ALPSO) is presented and the astringency analysis is(More)
The art of tiling originated very early in the history of civilization. Almost every known human society has made use of tilings in some form or another. In particular, tilings using only regular polygons have great visual appeal. Decorated regular tilings with continuous and symmetrical patterns were widely used in decoration field, such as mosaics,(More)
The dual-objective optimization of surface discussed in this paper means that the optimal surface is not only smoothing but also corresponded to the shape of the back of the body. Since surface can be built with family of curves which are optimized with the same two objectives, the mathematical model of surface's constructional curve is critical to the(More)
Aiming at the electromechanical coupling system dynamics optimization of spindle unit of refitted machine tool for solid rocket, the optimization modeling is presented on the basis of system differential equations. The research job in the paper reveals that the global optimization efficiency can be enhanced greatly, when the weight value of the swarm(More)
