用C Sharp编写一个Windows服务，有详细的图文并茂的编写设计文档。代码有注释，容易阅读。(The preparation of a Windows service by C Sharp, has detailed pictures and write design document. Annotated code, easy to read.)

MATLAB 牛顿下山法的一个小程序，原理就不详细说了。因牛顿迭代法受初值选取的限制，为防止迭代发散，对迭代过程再附加一项要求:|f(x(k+1))|<|f(x(k))|,将牛顿法迭代的结果:x(k+1) =x(k)-f(x(k))/f (x(k))和前一近似值x(k)适当加权平均做为新的改进值:x(k+1)=u*x(k+1) +(1-u)*x(k),其中u(0<> 迭代时u取1开始，逐次减半计算，直至附加要求符合为止。实例计算中x(k)=x(0)不变，只更新u和x(k+1)，直至:|f(x(k+1))|<|f(x(k))|（即|f(x(1))|<|f(x(0))|)，然后更新下山因子为u=1,继续以牛顿法迭代。(MATLAB Newton-down a small program, the principle is not explained in detail. Newton iteration by the initial value of the selected limit, in order to prevent additional iterative divergence, the iterative process a request: | f (x (k+1)) | < | f (x (k)) | Newton iteration Results: x (k+1) ' = X (k)-f (x (k))/f' (x (k)) and a previous approximation x (k), appropriately weighted average as a new improved value: x (k+1 ) = u* x (k+1) ' + (1-u)* x (k), where u (0 < u> iteration take successive calculated at 50 until the additional requirements found so far. examples of calculation of X ( k) = x (0) unchanged profile u and x (k+1, hungry) until: | f (x (k+1)) | < | f (x (k)) | (i.e. | f (x (1)) | < | f (x (0)) |), then profile downhill factor for u = 1, to continue to Newton iteration.)

这个matlb程序能够实现图像里面的刚兴趣区域的提取和分割(The matlab program to achieve extraction and image segmentation inside the region of interest)

海杂波的matlab仿真，希望对大家有用(Matlab simulation of sea clutter, in the hope that useful)

说明：  以航标、测绘和通信为主的三大板块，是我国水上交通安全保障体系的重要组成部分，承担 着船舶航行的技术支持和航运经济的服务保障职能，对我国水上交通安全形势的持续稳定发挥了 不可替代的重要作用。从上世纪七、八十年代起，随着我国水上交通安全监督体制改革的逐步深 入，航标、测绘、通信等机构先后经历了数次体制改革、机构变化和职责调整，逐步建立了具有 中国特色的航海保障体系。 (To buoy, mapping and communication of the three main sections, is an important part of water transportation security system, technical support and bear the shipping service guarantee economic functions of the ship sailing on a steady water traffic safety situation in our country to play an irreplaceable important role. From the 1970s, since the 1980s, with the gradual deepening of China' s reform of water traffic safety supervision, aids to navigation, mapping, communications and other institutions have experienced several reforms, institutional change and responsibilities adjustment, gradually established with Chinese characteristics maritime security system.)
