k means techniques de classification non supervisée (clustering) les plus utilisées. Etant donné un entier K, K-means partitionne les données en K groupes, ou "clusters", ou "classes" ne se chevauchant pas. Ce résultat est obtenu en positionnant K "prototypes", ou "centroï des" dans les régions de l espace les plus peuplées. Chaque observation est alors affectée au prototype le plus proche (règle dite "de la Distance Minimale"). Chaque classe contient donc les observations qui sont plus proches d un certain prototype que de tout autre prototype

能进行ofdma自适应资源分配的超好程序，本人花了很长时间琢磨出来的哦。(Adaptive resource allocation can be ofdma super good program, I took a long time figured it out, oh.)

Stretches contrast on the image and normalize image from 0 to 1. The main difference of this function to the standard stretching functions is that standard function finds global minimum and maximum on the image, then uses some low and high threshold values to normalize image (values below LowTHR are equated to LowTHR and values above HighTHR are equated to HighTHR)

针对davenport风速，用谐波分析法进行风速时程和风载模拟(Davenport on wind, the harmonic analysis method with wind speed schedule and wind load simulation)

该论文介绍了电磁场积分方程的无网格数值计算方法，传统的体积分数值计算都需要进行网格剖分，网格剖分的好坏直接影响着数值计算的速度和精度，很多精细结构很难用网格来模拟，无网格技术可以很好地解决此类问题！(This paper describes the meshless numerical method electromagnetic integral equations, numerical integration of traditional body calculations require meshing, meshing a direct impact on the speed and accuracy of numerical calculation, many very fine structure difficult to simulate with the grid, no grid can solve this problem!)
