For the propagation acoustic wave in inhomogeneous, we need to study Helmholtz equation, one of the difficulty is to cope with the big angular problem in the research of the propagation acoustic wave, so it is necessary to study the numerical method of isospectral problem. An numerical experiment of Newton iteration on Lie group of isospectral is introduced in this paper.
A new method based on best achievable flexibility change is presented in this study for structural damage localization. The algorithm makes use of an existing finite element model of the “healthy” structure and a subset of experimentally measured modal parameters of the “damaged” structure. Central to the damage localization approach is the computation of the Euclidean distances between the measured...
Fuzzy Fisher Criterion(FFC) based clustering method uses the fuzzy Fisher's linear discriminant(FLD) as its clustering objective function and is more robust to noises and outliers than fuzzy c-means clustering(FCM). But FFC can only be used in linear separable dataset. In this paper, a novel fuzzy clustering algorithm, called Kernelized Fuzzy Fisher Criterion(KFFC) based clustering algorithm, is proposed...
Objective: An intrusion detection system was constructed on the basis of the characteristics of BP neural network model. Methods: According to the capture engine of the text, all network data stream flowed through the systematic monitoring network segment will be captured, feature extraction module analyze and process the captured network data flow, you can extract complete and accurate eigenvector...
