Efforts have been performed on utilizing the dielectric barrier discharge actuator to control the flow separation over the top of the flap of a three-element airfoil. Images of the flow fields visualized by a particle image velocimetry system with actuators off and on at the free-stream speeds of 20 and 30 m/s are presented.
Sequence data plays an important role in data analysis applications, such as sequence classification. One important aspect of sequence data analysis is to obtain the labeled sequence data and use a machine learning model to predict the sequence structures. Conditional Random Fields (CRF) is such a machine learning method which is popular used in sequential data analysis. This is because that CRF can...
In the light of the problem of premature convergence and local convergence in particle swarm optimization (PSO), a clustering coefficient (λ) and a boundary restriction equation are introduced in the model of PSO at first. And a PSO with cyclical migratory behavior (CMPSO) is proposed based on the optimization of particles' work model. And then, the two parameters' characteristics of CMPSO, N which...
