PFC5.0-2D指定接触

% Input: XY(n,2) is the array of coordinates of n points x(i)=XY(i,1), y(i)=XY(i,2) % % Output: Par = [a b R] is the fitting circle: % center (a,b) and radius R % % Note: this fit does not use built-in matrix functions (except "mean"), % so it can be easily programmed in any programming language

It is a vending machine.

linux下通用服务器启动、停止脚本，很方便的!-under common server startup and stop scripts, very convenient!

界面漂亮的JSP聊天室程序，使用了基于jQuery实现的AJAX技术，运行前需要配置好JSP服务器，功能并不多，只实现了无刷新发送消息功能，帮助JSP新手更好的理解AJAX的使用。

这个是基于stm32的一系列开发产品，多功能多时效多应用(I loved the first time that Satan sent out a lot of VV ah multi-point algorithm.)

说明：  三轴代码颗粒流问题是众多工农业生产领域中的常见问题，然而人 们至今对颗粒流机理认识不深。目前一种基于离散元的数值模拟方 法被用以模拟和分析颗粒流问题，研究实践表明该方法是散体力学 分析的一种有效的工具，PFC 3d离散单元法在岩土工程真三轴中使用广泛。(Particle flow is a common problem in many fields of industrial and agricultural production Up to now, the mechanism of particle flow is not well understood. A numerical simulation method based on discrete element The method is used to simulate and analyze particle flow problems. The research practice shows that the method is granular mechanics PFC 3D discrete element method is an effective tool for analysis, which is widely used in true triaxial analysis of geotechnical engineering.)

说明：  核密度估计(kde)的工具箱,来源于 Copyright (C) 2003 Alexander Ihler(The KDE class is a general matlab class for k-dimensional kernel density estimation. It is written in a mix of matlab ".m" files and MEX/C++ code. Thus, to use it you will need to be able to compile C++ code for Matlab. Note that the default compiler for Windows does not support C++, so you will need GCC under Linux, or GCC or Visual C++ for Windows. Bloodshed supplies a nice development environment along with the MinGW compiler. See this page for help setting up MEX with MinGW.)

Delphi图片管理程序，可对图片进行分类管理，以前见到有朋友用.NET写的照片分类管理程序，用起来也挺好，只不过要安装.NET框架才行，觉得不太方便，我用Delphi2007仿写了一个，界面也基本一样啦，再次感谢那位朋友了。

不同节点数对吞吐率的影响，分别为5节点数和20节点数时的吞吐量的对比情况(The influence of different number of nodes on the throughput of the five nodes and the number of 20 nodes was compared.)
