理解随机信号功率谱分析原理和方法。 (1) 生成信号，被淹没在在噪声中； (2) 试用周期图法估计信号的功率谱； (3) 选用不同窗，使用修正周期图法估计信号的功率谱； (4) 对一段语音信号，使用LD算法估计其功率谱； (5) 详细列出功率谱估计的步骤和原理。 (understanding of random signal power spectrum analysis principles and methods. (1) generate signals being drowned in the noise; (2) The probationary period plan estimates the signal power spectrum; (3), different windows, the use of map amendment cycle method to estimate the power spectrum signal; (4) a voice signal, the use of LD algorithm to estimate the gong spectrum; (5) a detailed breakdown of the power spectrum estimation steps and principle.)

全国大学生数学建模问题,是非常重要的国家级赛程，这对于我们很有帮助的啊！(National Mathematical modeling is very important for evey students,so it is very good for prevent students,and,it is good for our.)

Improving Compressed Air System Performance

频谱选取，一般用于后续向量机的诊断的特征。进行了频谱分析后对每个频带的能量进行分离开。(Spectral selection, generally for subsequent diagnostic feature vector machine. Spectrum analysis conducted after the energy of each frequency band to leave.)

说明：  用于压缩感知的各种稀疏变换基和观测矩阵，有具体的源程序，是用matlab编程的。(Compressed sensing for a variety of sparse matrix transform bases and observations, a specific source is using matlab programming.)

Cours Roc Curve tres utiles Rappels sur la courbe ROC (Receiver Operating Characteristic Curve) Supposons qu une population soit répartie en deux classes notées respectivement 1 et 0. Mais, au lieu d observer directement la classe à laquelle appartient un sujet, on dispose de renseignements sur chaque sujet, permettant d en déduire la classe à laquelle il appartient avec une certaine probabilité d erreur.
