这是一个关于SIFT算法介绍的pdf和ppt的合集，可以很好地帮助初学者了解sift算法。（中英文都有）(This is a collection of pdf and ppt about SIFT algorithm. I believe it can greatly help beginners to understand SIFT algorithm.)

特征值分析，便于模态分析电网稳定态态势分析和薄弱环节识别(Eigenvalue analysis, to facilitate modal analysis grid steady state trend analysis and identification of weak links)

地震数据通常含有噪音，通过该方法可以去除地震数据中的噪音，更好的反演结果(Seismic data usually contains noise, the method can remove the noise in the seismic data, better inversion results)

瑞利衰落信道仿真,基于Matlab的瑞利衰落信道仿真程序序源代码，还可以用C++来进行编程，已通过测试。 (Rayleigh fading channel simulation, has been tested Matlab Rayleigh fading channel simulation program sequence source code, you can also C++ programming.)

计算小波能量谱分析，用于功率谱分析，以及损伤等都可以(Calculating wavelet energy spectrum analysis)

很好的matlab/simulink电子书(ebooks on matlab/simulink)

这里我们针对三级固体火箭进行研究，主要考虑每一级发动机工作时推力 和比冲 与发动机试车存在摄动偏差（相差 ）时所产生火箭关机点时刻的状态偏差。火箭的飞行的动力学方程可建立在地面发射坐标系中，火箭的第一级、第二级和第三级按照固定的俯仰角程序飞行，第二、三级飞行时已在大气层外，此时可忽略气动力的影响。(Here we study for three solid rocket, the main consideration at every level when the engine thrust and state arising the moment the rocket off point perturbation deviation (difference) in the presence of specific impulse and engine test bias. Outside of the rocket flight dynamics equations can be established on the ground coordinate system launch, the rocket s first stage, the second and third stages according to a fixed elevation angle of flight procedures, and the second, when the third flight already in the atmosphere, this when can ignore the effects of gas dynamics.)
