基于ARMFPGA的EtherCAT主站设计及实现，讲解了基于ARM与FPGA的EtherCAT主站实现。

倒立摆系统是自动控制理论中比较典型的控制对象,许多抽象的控制理论概念如系统稳定性、可控性和系统抗干扰能力等,都可以通过倒立摆系统直观地表现出来。因此它成为自动控制理论研究的一个较为普遍的研究对象。倒立摆系统作为一个被控对象,是快速、多变量、开环不稳定、非线性的高阶系统,必须施加十分有力的控制手段才能使之稳定。本文是通过模糊控制来实现其稳定的。

LSD: a Line Segment Detector文章中的方法，由于原网站上只公布了open CV的 代码，这个是matlab 的实现代码，精度比霍夫变换高不止一个数量级，只需运行主函数Mainfun即可，无需安装，无需任何配置。只要把自己的图像输进去，就可以了，牛逼的话，你还可以再次版本上完善，修改。

自己编写整理的双线性插值算法原理，内含原理和实例源码，给大家分享。

在Matlab的平台上,应用QPSK调制,以及3种不同的探测方法,实现并模拟了2x2的MIMO功能.

在地下黑客论坛上出售的Zeus恶意程序工具包的源代码（RAR，9.2MB）被人泄露，现在任何感兴趣的人都可以去了解一下这个臭名昭著但名声卓著的黑客工具包。上周，安全公司CSIS的研究人员从论坛上下载了一份拷贝，证实是Zeus的完整源代码。Zeus可用于制作木马，创建僵尸网络。它的售价过去非常昂贵，最高接近5000美元。源代码的泄露意味着销售市场的崩溃，随之而来的结果可能是会出现很多修改和改进版本，网民面临的风险将会加大。

MOTIVATIONPropeller related acoustic signatures typically exhibit modulationcharacteristics. These modulation characteristics originate from the cavitationprocess that takes place in the water due to the cyclic movement of the propellerThe cavitation process is basically the collapse of air and vapor bubblesdue to variations in the static pressure. These variations in static pressure are aconsequence of the passage of the propeller blades through the water. Thismovement, cyclic in nature, causes amplitude modulation in the static pressureand as a consequence an amplitude-modulated(AM) signal can be detected in areceiverCyclostationary processing techniques have been used to detect andlentify analog and digital communication signals very successfully. Thesetechniques have the advantage of using a more realistic model for the signalthan the stationary model used in most of the more conventional signalprocessing techniquesB BACKGROUNDThe basic elements of cyclic spectral analysis are the time-variant cyclicperiodogram and the time-variant cyclic correlogram. These two functions form aFourier transform pair. This fact is known as the cyclic Wiener relation or thecyclic Wiener-Khinchin relation [Ref. 1: p. 49.1
