用神经网络实现故障诊断的matlab程序(Fault diagnosis using neural networks in matlab program)

简要概述了最具代表性的分形结构--扩散限制凝聚(Diffusion-Limited-Aggregation,DLA)模型的生长规则、主要性质,给出了模型模拟分形生长的算法,在MATLAB6.5平台上进行了程序设计,在Windows98/2000/XP下实现了DLA模型模拟生长的动态过程.(Briefly summarizes the most representative of the fractal structure- diffusion-limited condensed (Diffusion- Limited- Aggregation, DLA) model of growth rules, the main properties, gives the model simulation processes-fractal growth algorithm, by MATLAB6.5 platform for software design, in Windows 98/2000/XP realize DLA model to simulate the growth of dynamic process.)

遗传算法是模拟达尔文的遗传选择和自然淘汰的生物进化过程的计算模型。它的思想源于生物遗传学和适者生存的自然规律，是具有“生存＋检测”的迭代过程的搜索算法。遗传算法以一种群体中的所有个体为对象，并利用随机化技术指导对一个被编码的参数空间进行高效搜索。(Genetic algorithm is simulated Darwinian natural selection of genetic selection and evolution process model. It' s thought from biological genetics and survival of the fittest laws of nature, is a " survival+ detection" iterative process of search algorithm. Genetic algorithms in a group all the individuals targeted, and technical guidance on the use of a randomized coded efficiently search parameter space.)

说明：  这是个关于图像分水岭分割算法的源程序，用matlab实现。(This is a watershed segmentation algorithm on the image source, using matlab to achieve.)

Logitboost 是一种改进的boostingg算法，可以用作参考 ， (Logitboost an improved boostingg algorithm can be used as a reference,)

F检验函数，用于直接调用的F检验函数，可以使编程更加方便(F test function)

本内容为，三维模型直接导入matlab中，可以方便的运行，可以更观的体现模型的真实性(This content is, three-dimensional model directly into matlab, you can easily run, you can view more manifestation of the authenticity of the model)

这是一篇关于高斯伪谱法的源代码，具有很好的指导意义(This is a Gaussian pseudo-spectral method on the source code, with a good guide)

一个MATLAB GUI程序，可以方便地用来手动标记正训练样本和负训练样本。 —————————————————— 1.首先输入要标定的数据库目录、要存放正训练样本的目录、要存放负训练样本的目录 2.点击“开始”，程序自动依次显示数据库目录中的图片 3.点击“正例”或“反例”将会把当前图片复制到相应目录 4.可以在图片上点击拖动圈出一个区域，以截取圈出的区域作为样本 5.选中“约束选取比例”可以使得最终选取的样本有固定的大小(A matlab GUI program that can be used to label training samples manually. It contains rich functions)

石油管道环境下超长波发射器的电磁场建模，用于描述管道环境，包含边界条件。(Oil pipeline under long wave electromagnetic field transmitter model, used to describe the pipeline environment, including boundary conditions.)
