State Space Basics State space models are of the form x()= Ax(t)+ Bult) y(t)= Cx(t)+ Dult) with associated transfer function G()=C(sI-A)

1、一个40KW、10Q的电阻,使用时至多能容许A的电流通过。 2、若流入某一节点有4个电流,已知i1=5A,i2=2A,3=-3A,那么

1 题解: （略） 2 题解:A1 基因的频率: (384×2+210)/854=57.3% A2 基因的频率:(260×2+210)/854=42.7%3 题解: 题中bb基因型频率为4%；BB+Bb基因型的频率为96%。则b基因的频率为0.2；B基因的频率为1-0.2=0.8

Interpretation over a singleton Let I be , and σ ∈ ΣI. 1. I(A)(σ) = I(∀xA)(σ). 2. I(t)(σ) = a. 3. I(Sx1,···,xn t1,···,tn A)(σ) = I(A)(σ). 4. I0(P), σ(P) ∈ {I(n), Ψ(n)} for every n-ary predicate constant (variable), where

一、原函数与不定积分的概念 定义:如果在区间内,可导函数F(x)的 导函数为f(x),即Vx∈I,都有F'(x)=f(x) 或dF(x)=f(x)dx,那么函数F(x)就称为f(x) 或f(x)dx在区间内的一个原函数 例(sinx)=cos sinx是cosx的原函数

1 Model problem 1.1 Poisson Equation in 1D Boundary Value Problem(BVP) (x)=∫(x) (0,1),u(0)=(1)=0,f Describes many simple physical phenomena(e.g) Deformation of an elastic bar Deformation of a string under tension Temperature distribution in a bar The Poisson equation in one dimension is in fact an ordinary differ tion. When dealing with ordinary differential equations we Poisson equation will be used here to illastrate numerical techniques for elliptic PDE's in multi-dimensions. Other techniques specialized for ordinary differen tial equations could be used if we were only interested in the one dimension
