According to former research products , when choosing rigid node , analysis in structure analysis , especially in non - linear analysis of slts will be reasonable 前人研究成果表明,进行网架结构分析特别是非线性分析时节点选择刚接会使计算分析结果更为合理。
Based on this idea , a general framework for linear analysis in singular case is developed , i . e . , pca is first used to reduce the dimension of image space to m ( the rank of the total scatter matrix ) 更为重要的是,我们进一步揭示了高维、小样本情况下线性鉴别分析的本质,即先作k - l变换,再用fisher鉴别变换作二次特征抽取。
Following the linear analysis , a new nonlinear theory for curved members with i - shaped sections is presented according to the theory of finite deformation , in which the effect of transverse stress is also incorporated 在线性分析的基础上,依据有限变形理论,建立了工字形曲梁涉及稳定问题的非线性理论,其中考虑了横向正应力的影响。
Since most of the general predicting methods are based on linear analysis , when it comes to non - linear cases they met many difficulties , while ann is competent for non - linear proceeding for its excellent non - linear character 经典的预测方法用于非线性系统预测有一定困难。而神经网络具有优良的非线性特性,特别适用于高度非线性系统的处理。
The traditional encryption algorithm ' s security intensity is scarcity , its key " length is too short to resist the attack of the differential cryptanalysis and linear analysis , and exist considerable serious safe trouble 传统的des等加密算法安全强度不足,主要表现在密钥长度过短、不能抵御差分分析和线性分析攻击,因而存在相当大的安全隐患。
