rate; induced feature 1 Introduction Magnesium and aluminum alloys have become more and more attractive in designing vehicle, aircraft, and other products [1-5]. Thin-walled structures made from... magnesium and A6063 aluminum thin-walled square tubes with varied lengths and induced features at different compression rates. In compression, the magnesium tubes exhibited a "local buckling......
文献标志码:A 文章编号:1672-7207(2010)06-2386-07 Joint-action induced deformation feature of low-cap group... and soil based on the elastic theory was improved to be more reasonable and accurate. Based on the improved equation, a program was written to analyze joint-action induced deformation feature of low-cap......
J. Cent. South Univ. (2012) 19: 488-495 DOI: 10.1007/s11771-012-1030-5 Modified Fourier descriptor for shape feature extraction ZHANG Gang(张刚)1, MA Zong-min(马宗民)2, NIU Lian-qiang(牛连强)1, ZHANG Chun... in a feature space. Then, Fourier transform was used for composition of point information in the feature space so that the shape features could be computed. It is proved theoretically that the shape features......

After studying the feature of resistivity response of slope failure, the variety of resistivity during evolution of slope from steady to unsteady was found......
Adaptive WNN aerodynamic modeling based on subset KPCA feature extractionMeng Yue-bo(孟月波)1,2, Zou Jian-hua(邹建华)1, Gan Xu-sheng(甘旭升)3, LIU Guang-hui(刘光辉)2(1. Systems Engineering Institute, School... modeling, an adaptive wavelet neural network (AWNN) aerodynamic modeling method is proposed, based on subset kernel principal components analysis (SKPCA) feature extraction. Firstly, by fuzzy C-means......
Seismic signal recognition using improved BP neural network and combined feature extraction methodPENG Zhao-qin(彭朝琴)1, CAO Chun(曹纯)1, HUANG Jiao-ying(黄姣英)2, LIU Qiu-sheng(刘秋生)3(1. School... and vehicle was acquisitioned from the seismic sensor, and then feature vectors were extracted with combined methods after filter processing. Finally, these features were put into the improved BP neural network......
