在工程应用中 经常会遇到一些复杂的非线性系统, 这些系统状态方程复杂, 难以 用数学方 法准确建模。 在这种情况下, 可以 建立 BP 神 经网 络表达这些 非 线 性系 统。 该方法把未 知 系 统看成是一个黑箱, 首先用 系 统 输入输出 数据 训 练 BP 神 经网 络, 使网 络能 够表达该未 知 函 数, 然后就可以 用训练好的 BP 神经网络预测系统输出 。 本章拟合的非线性函 数为 y = x1^2+x2^2. 。 (In engineering applications often encounter some complex nonlinear systems, which complicated the equation of state, can not be accurately modeled mathematically. In this case, BP neural network can be established to express these nonlinear systems. The method of the unknown system as a black box, the first input and output data with systematic training BP neural network, the network can express the unknown function, then you can use the trained BP neural network forecasting system output. Chapter for fitting non-linear function y = x1 ^ 2+x2 ^ 2..)

为研究局部阴影效应对光伏发电系统的影响，首先建立了光伏阵列工程数学模型，分析局部阴影条件下光伏阵列的输出特性。为了便于工程分析，该文利用PVSYST软件分析比较单晶硅、多晶硅和薄膜电池等3种不同材料光伏电池在局部阴影条件卜的输出功率，为工程应用提供了良好的指导作用。最后提出了几种提高光伏阵列抗局部阴影能力的措施厂 (To investigate the effect of local shading effects on photovoltaic systems, photovoltaic array project was first established mathematical model to analyze the output characteristics under conditions of partial shading of the PV array. In order to facilitate engineering analysis, this paper use PVSYST software analysis and comparison monocrystalline, polycrystalline and thin film batteries, photovoltaic cells of three different materials in partial shade conditions Bu output power for engineering applications provide a good guide. Finally, several photovoltaic arrays to improve the ability to measure resistance to partial shade plant)

This is a program for extracting objects from an image. Written for vehicle number plate segmentation and extraction. Authors : Jeny Rajan, Chandrashekar P S. U can use attached test image for testing input - give the image file name as input. eg :- car3.jpg(This is a program for extracting objects from an image.
