This paper studies operational optimization design in industrial processes with constrained operational conditions when the operational state is transmitted via wireless networks, inducing noise and packet dropout which negatively affect operational optimization performance. Firstly, given a constrained-input process, a PI controller is designed to stabilize the plant without any steady-state error...
A novel unsupervised scheme for natural image segmentation is proposed aiming to acquire perceptually consistent results. Firstly, comprehensive visual features besides raw color values are extracted, including spatial frequency, contrast sensitivity, color deviation, and so on. Secondly, high correlations among visual features are reduced via principal component analysis (PCA) and the raw image pixels...
