Image Compression by: 1) Use Adobe Photoshop to Compress images using LZW algorithm (i.e. lossless technique). 2) Use MATLAB to Compress images using JPEG algorithm (i.e. lossy technique) and Assess objectively the quality of the compressed images

比较均匀量化和A律13折线编码的信号量噪比，通过比较可以看出两者的区别。但不知道正不正确(A law more uniform quantitative and broken line 13 the amount of coded signal to noise ratio, can be seen by comparing the difference between the two. But do not know is not correct)

利用传统有限元方法计算二维possion 方程的特征值问题，网格采用的是三角网格，由matlab 的pdetool产生，一次多项式近似(Using traditional two-dimensional finite element method possion equation eigenvalue problem, the grid uses a triangular mesh is generated by the matlab pdetool, a polynomial approximation)

In the following figure is a system of two water tanks. Mass flow into the top tank at a fixed rate q0 and exits this tank through an orifice of area A1. This exit water then flows into a second tank which has an orifice of area A2 at its bottom. Each tank has constant cross section of area A, with A>>A1,A2. (a) Determine the ODE model which governs the heights z1 and z2 of water in the system. (b) Determine the equilibrium given a fixed rate q0. (c) Linearize the system model about the equilibrium. (d) Compare the step responses of the nonlinear model and linearized model by choosing reasonable system parameters. ( (b) Plot the flow v.s. pressure drop curve with the estimated c to validate your estimation
