1如果已经装了originInstaller_v8.6.SR2.x86 以右键管理员运行originInstaller_v8.6.SR2.x86可以更新软件到originInstaller_v8.6.SR3.x86 2、用crack中得ok9.dll文件，替代C:\Program Files\originLab\origin的ok9.dll文件 （假如你安装在C盘的话，其它盘把c改为你的盘符），点覆盖 3、如果你是windows xp的话，在地址栏复制C：\Documents and Settings\All Users\Application Data\回车， 在该目录下建立originLab文件夹，再在originLab文件夹下建立86文件夹，再在86文件下建立License文件夹， 然后把Crack文件夹下的所有文件拷贝在License文件夹下。 win7，win8要把文件拷贝C：\ProgramData\originLab\86\License\下（一般要取得管理员权限） 4 然后把汉化补丁放在安装目录下即可 可以按照如下步骤安装originInstaller_v8.6.SR3.x86 1、安装程序originInstaller_v8.6.SR3.x86 2、用序列号GF3S4-9089-7991320安装 3、用crack中得ok9.dll文件，替代C:\Program Files\originLab\origin的ok9.dll文件 （假如你安装在C盘的话，其它盘把c改为你的盘符），点覆盖 4、如果你是windows xp的话，在地址栏复制C：\Documents and Settings\All Users\Application Data\回车， 在该目录下建立originLab文件夹，再在originLab文件夹下建立86文件夹，再在86文件下建立License文件夹， 然后把Crack文件夹下的所有文件拷贝在License文件夹下。 win7，win8要把文件拷贝C：\ProgramData\originLab\86\License\下（一般要取得管理员权限） 5、运行origin86然后输入GRM-RVR-AR2 ok 6 然后把汉化补丁放在安装目录下即可 补充:汉化补丁只有originInstaller_v8.6.SR3.x86才能用

matlab有限元网格划分程序 DistMesh is a simple MATLAB code for generation of unstructured triangular and tetrahedral meshes. It was developed by Per-Olof Persson (now at UC Berkeley) and Gilbert Strang in the Department of Mathematics at MIT. A detailed description of the program is provided in our SIAM Review paper, see documentation below. One reason that the code is short and simple is that the geometries are specified by Signed Distance Functions. These give the shortest distance from any point in space to the boundary of the domain. The sign is negative inside the region and positive outside. A simple example is the unit circle in 2-D, which has the distance function d=r-1, where r is the distance from the origin. For more complicated geometries the distance function can be computed by interpolation between values on a grid, a common representation for level set methods. For the actual mesh generation, DistMesh uses the Delaunay triangulation routine in MATLAB and tries to optimize the node locations by a force-based smoothing procedure. The topology is regularly updated by Delaunay. The boundary points are only allowed to move tangentially to the boundary by projections using the distance function. This iterative procedure typically results in very well-shaped meshes. Our aim with this code is simplicity, so that everyone can understand the code and modify it according to their needs. The code is not entirely robust (that is, it might not terminate and return a well-shaped mesh), and it is relatively slow. However, our current research shows that these issues can be resolved in an optimized C++ code, and we believe our simple MATLAB code is important for demonstration of the underlying principles. To use the code, simply download it from below and run it from MATLAB. For a quick demonstration, type "meshdemo2d" or "meshdemond". For more details see the documentation.

The TAS3204 is a highly-integrated audio system-on-chip (SOC) consisting of a fully-programmable, 48-bit digital audio processor, a 3:1 stereo analog input MUX, four ADCs, four DACs, and other analog functionality. The TAS3204 is programmable with the graphical PurePath Studio™ suite of DSP code development software. PurePath Studio is a highly intuitive, drag-and-drop environment that minimizes software development effort while allowing the end user to utilize the power and flexibility of the TAS3204’s digital audio processing core. TAS3204 processing capability includes speaker equalization and crossover, volume/bass/treble control, signal mixing/MUXing/splitting, delay compensation, dynamic range compression, and many other basic audio functions. Audio functions such as matrix decoding, stereo widening, surround sound virtualization and psychoacoustic bass boost are also available with either third-party or TI royalty-free algorithms. The TAS3204 contains a custom-designed, fully-programmable 135-MHz, 48-bit digital audio processor. A 76-bit accumulator ensures that the high precision necessary for quality digital audio is maintained during arithmetic operations. Four differential 102 dB DNR ADCs and four differential 105 dB DNR DACs ensure that high quality audio is maintained through the whole signal chain as well as increasing robustness against noise sources such as TDMA interference. The TAS3204 is composed of eight functional blocks: Clocking System Digital Audio Interface Analog Audio Interface Power supply Clocks, digital PLL I2C control interface 8051 MCUcontroller Audio DSP – digital audio processing 特性 Digital Audio Processor Fully Programmable With the Graphical, Drag-and-Drop PurePath Studio™ Software Development Environment 135-MHz Operation 48-Bit Data Path With 76-Bit Accumulator Hardware Single-Cycle Multiplier (28 × 48)

共轭梯度法为求解线性方程组而提出。后来，人们把这种方法用于求解无约束最优化问题， 使之成为一种重要的最优化方法。 共轭梯度法的基本思想是把共轭性与最速下降方法相结合， 利用已知点处的梯度构造一组共 轭方向， 并沿这组方向进行搜索， 求出目标函数的极小点。 根据共轭方向的基本性质， 这种 方法具有二次终止性。 在各种优化算法中， 共轭梯度法是非常重要的一种。 其优点是所需存 储量小，具有步收敛性，稳定性高，而且不需要任何外来参数。 共轭方向 无约束最优化方法的核心问题是选择搜索方向 . 在本次实验中 , 我们运用基于共轭方向的一种 算法 — 共轭梯度法 三．算法流程图： 四．实验结果： (1). 实验函数 f=(3*x1-cos(x2*x3)-1/2)^2+(x1^2-81*(x2+0.1)+sin(x3)+1.06)^2+(exp(-x1*x2)+20*x3+ 1/3*(10*3.14159-3))^2; 给定初始点 (0,0,0) ， k=1 ，最 大迭代次数 n d 确定搜索方向 进 退 法 确 定 搜 索 区 间 分割法确定最 优步长

32feet.NET is a shared-source project to make personal area networking technologies such as Bluetooth, Infrared (IrDA) and more, easily accessible from .NET code. Supports desktop, mobile or embedded systems. 32feet.NET is free for commercial or non-commercial use. If you use the binaries you can just use the library as-is, if you make modifications to the source you need to include the 32feet.NET License.txt document and ensure the file headers are not modified/removed. The project currently consists of the following libraries:- Bluetooth IrDA Object Exchange Bluetooth support requires a device with either the Microsoft, Widcomm, BlueSoleil, or Stonestreet One Bluetopia Bluetooth stack. Requires .NET Compact Framework v3.5 or above and Windows CE.NET 4.2 or above, or .NET Framework v3.5 for desktop Windows XP, Vista, 7 and 8. A subset of functionality is available for Windows Phone 8 and Windows Embedded Handheld 8 in the InTheHand.Phone.Bluetooth.dll library.
