In this paper, the shape features of different material of flame and interference image in video fire detection were analyzed and compared. The area, perimeter, rotundity, solidity, extent, sharp corners, similarity and centroid displacement are selected as the candidate features. After analyzing and excluding area and perimeter as these candidate features, weak classifiers of six other shape features...
An analysis method for power system transient signal is proposed in this paper to improve the analysis precision for the transient signal including harmonic, inter-harmonic and decaying DC component. First of all, the multiple wavelet method is adopted to cut down the noise, and the differential algorithm is used to wipe off the decaying DC component whereas to magnify high frequency components. Then...
Based on the features such as high convergence rate and global optimization of Support Vector Machine (SVM) which follows structure risk minimization principle, a method of fire detection is proposed, in which the shape of bright areas are analyzed by SVM and results are produced. After collecting images of fire and interference source under different conditions, data of shape features are extracted...
the performance of quantum genetic algorihtm is better than the common genetic algorithm such as species diversity, convergence and golbal optimal ability. Based on the analysis of the idiographic configuration of the shipboard power system and the characteristic of the collocation of its protection, the fault diagnosis model is presented considering the influence of each protection and the joint...
This paper considers the guaranteed cost control problem for a class of uncertain linear systems with both state and input delays. By representing the time-delay system in the descriptor system form and using a recent result on bounding of cross products of vectors, we obtain new delay-dependent sufficient conditions for the existence of the guaranteed cost controller in terms of linear matrix inequalities...
