In going from the state space model i(t)=A.(t)+ Bu(t y(t)= Ca(t)+ Du(t) to the transfer function G(s)=C(sI -A)-B+D need to form the inverse of the matrix(sI- A)-a symbolic inverse- not easy at all For simple cases, we can use the following

Strain energy and potential energy of a beam brec sedans hoMe the neutra xxis remain So Figure 1: Kinematic assumptions for a beam Kinematic assumptions for a beam: From the figure: AA'=u3(a1) Assume small deflections: B B\,BB\=3+ duy

We live in a shell, so to speak, a private, personal shell inside which takes place an immense variety of experiences

在对比品尝及二三品尝中，当回答两个酒样是否有差异时，即进行差异判断时，或回答： A≠B 或 A=B (对比品尝)；或回答：A=对照，则 B≠对照 或 B=对照，则 A≠对照 (二三品 尝)。 因此，我们只能获得正确和错误的两种回答(随机选择的概率为 0.5)
