zemax源码: This DLL models an anamorphic aspheric surface. This surface is essentially an even aspheric surface with different terms for the x and y directions. The sag is given by: Z = ((CX*x*x)+(CY*y*y)) / (1 + sqrt(1-((1+KX)*CX*CX*x*x)-((1+KY)*CY*CY*y*y))) + AR*( (1 - AP)*x*x + (1 + AP)*y*y )^2 + BR*( (1 - BP)*x*x + (1 + BP)*y*y )^3 + CR*( (1 - CP)*x*x + (1 + CP)*y*y )^4 + DR*( (1 - DP)*x*x + (1 + DP)*y*y )^5 Note the terms AR, BR, CR, and DR ... have units of length to the -3, -5, -7, and -9 power. The terms AP, BP, CP, and DP are dimensionless. The surface is rotationally symmetric only if AP = BP = CP = DP == 0 and CX = CY and KX = KY.

his project was built and tested with WinAVR-20060125. Make sure the MCU target define in the Makefiles corresponds to the AVR you are using!! To build the code, just install WinAVR and run "make" from the console in echomaster and echoslave subdirs. "make program" will program the device if you have a AVRISP attached. Remember to set the AVR device to at least 8MHz. The AVR may use the programmable clock from MC1319x, just remember to check if the MC1319x and SPI communication is working FIRST! Otherwise you wont get any clock signal to the AVR and then you can t program it or reset the fuses! The MC1319x has default clock output of 32kHz so you will have to set your programmer to a very low frequency (<=32kHz/4) to be able to program it while it is running on that!

处理机调度,编写一个进程调度程序,允许多个进程共行的进程调度程序。 进程调度算法:采用最高优先数优先的调度算法(即把处理机分配给优先数最高的进程)和先来先服务算法。 每个进程有一个进程控制块(PCB)表示。进程控制块可以包含如下信息:进程名、优先数、到达时间、需要运行时间、已用CPU时间、进程状态等等。 进程的优先数及需要的运行时间可以事先人为地指定(也可以由随机数产生)。进程的到达时间为输入进程的时间。 进程的运行时间以时间片为单位进行计算。 每个进程的状态可以是就绪 W(Wait)、运行R(Run)、或完成F(Finish)三种状态之一。 就绪进程获得 CPU后都只能运行一个时间片。用已占用CPU时间加1来表示。 如果运行一个时间片后,进程的已占用 CPU时间已达到所需要的运行时间,则撤消该进程,如果运行一个时间片后进程的已占用CPU时间还未达所需要的运行时间,也就是进程还需要继续运行,此时应将进程的优先数减1(即降低一级),然后把它插入就绪队列等待CPU。 每进行一次调度程序都打印一次运行进程、就绪队列、以及各个进程的 PCB,以便进行检查。 重复以上过程,直到所要进程都完成为止

This a software runing on the matlab, it is used in the channel coding simulation. It include DVB-S2 LDPC, Covolution turbo, and block turbo code, You can choose which channel coding to run. it run the encoder and add white noise in the channel, then it run the decoder, and compute the error rate.

maven 2.0 The following instructions show how to install Maven 2: 1) Unpack the archive where you would like to store the binaries, eg: tar zxvf maven-2.0.tar.gz or unzip maven-2.0.zip 2) A directory called "maven-2.0" will be created. 3) Add the bin directory to your PATH, eg: export PATH=/usr/local/maven-2.0/bin:$PATH or set PATH="c:\program files\maven-2.0\bin" %PATH% 4) Make sure JAVA_HOME is set to the location of your JDK 5) Run "mvn --version" to verify that it is correctly installed.

The objective of this projectis to design, model and simulate an autocorrelation generator circuit using 4-bit LFSR. the register and LFSR will used D flip-flop and some gates. By the autocorrelation concept, there should be 2 same length vectors, for calculating the autocorrelation , we have to design the register for storing the original vector and the shifter for make time delay.

KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware. It consists of a loadable kernel module (kvm.ko) and a userspace component. Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc. The kernel component of KVM is included in mainline Linux, and will appear in Linux 2.6.20. KVM is open source software.
