2009年各类数学建模论文集

平均或标准差，通常计算了信号的分析，整体的一部分。但是，有时我们想知道这个数量在不断变化的数据流。 MEANSTDF计算预期的平均值和标准偏差值使用定义为每一个用户的数据的位置窗口。输出可能是有用的，而非线性趋势化和平稳性分析。-Mean or standard deviation are usually computed for whole part of the analysed signal. However, sometimes we would like to know how this quantities are changing in the data flow. MEANSTDF compute the expected mean and standard deviation values using user defined window for every data position. The output can be useful while nonlinear detrending or stationarity analysis.

这是用C语言编写的一个小程序，它的结果是演示物理实验中的李萨如图。运行程序的时候需要把CCBP文件夹包含在头文件中。-This is the C language of a small program, and the result is a demonstration of physics experiments Lissajous figure. When operational procedures need CCBP folder contains the first document.

抗差Kalman滤波，抗差最小二乘等matlab源代码(Robust Kalman filtering, robust least squares matlab source code)

说明：  本书从电子技术和通信系统的角度讲解gps接收机的设计开发原理，其内容集中在用户终端，即接收机的设计原理和软件实现上。全书分为两大部分，第一部分为理论篇，第二部分为实现篇。理论篇首先对导航的基本目的进行了阐述，并由一个浅显的二维导航系统对导航信号的特点进行了推导，随后阐述了gps信号格式，同时对于直接影响接收机性能的射频前端部分做了理论分析；实现篇主要对本书实现的软件gps接收机的系统实现和源代码进行了讲解，同时作为总结，将信号处理的结果和有意义的中间变量以图示的方式给出，可以使读者有一个感性的认识，同时提升学习兴趣。. 本书适合从事卫星导航接收机研发的技术人员和卫星通信接收机研究的研究人员，尤其是从事北斗系统研发的专业人员、cdma通信系统研发人员，以及通信电子类专业的高年级本科生和研究生阅读，既可作为教学培训的教材，也可作为相关专业工程技术人员的参考资料。(This book explains the design and development principle of the GPS receiver from the perspective of electronic technology and communication system. Its content focuses on the design principle and software implementation of the user terminal, that is, the receiver. The whole book is divided into two parts. The first part is the theoretical part and the second part is the realization part. Firstly, the basic purpose of navigation is expounded, and the characteristics of navigation signal are deduced by a simple two-dimensional navigation system. Then, the format of GPS signal is expounded. At the same time, the front-end part of radio frequency which directly affects the performance of the receiver is theoretically analyzed.)

此程序用fortran编写 功能: 1、是计算在载荷作用下的平面桁架位移以及杆件的轴力。轴力符号规定，受拉为正，受压为负。另外还哼计算支座反力。 2、对桁架的节点编号，采取先编可动节点，接着再编固定节点。 3、计算多工况问题 此程序出自《杆系结构程序设计》，有改动，原程序有错误-the procedure used to prepare fortran functions : 1. calculation of the load under the plane truss rod displacement and the axial force. Symbol axial force, the tension is positive, negative pressure. It also supports anti-hum calculating power. 2, the number of nodes truss, the first series to take movable joints, and then re-allocation fixed nodes. 3, the calculation of multi-state issues this procedure from the "bar structural design process," with changes, the original procedure is wrong

Latex教程，东北大学薛定宇教授编著，一本相当不错的参考书(Latex tutorials, Professor Xue Dingyu, Northeastern University, has compiled a pretty good reference )

使用图形库，利用c++语言实现了界面化五子棋小游戏(Realize the interface game of Gobang)

随机有限元程序及算例，有学习价值，用FORTRAN语言写的-Stochastic finite element program and example, have learning value, written in FORTRAN language

说明：  使用Python语言在数字设计中，有很多优势比如算法建模，RTL模板生成等优势(Use Python in ASIC design)

说明：  jQuery缩略图排列焦点图是一款酷炫的响应式图像滑块缩略图旋转木马。(JQuery Thumbnail Arrangement Focus Map is a cool responsive image slider thumbnail merry-go-round.)
