zemax源碼： 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!

處理機(jī)調(diào)度，編寫一個(gè)進(jìn)程調(diào)度程序，允許多個(gè)進(jìn)程共行的進(jìn)程調(diào)度程序。 進(jìn)程調(diào)度算法：采用最高優(yōu)先數(shù)優(yōu)先的調(diào)度算法（即把處理機(jī)分配給優(yōu)先數(shù)最高的進(jìn)程）和先來先服務(wù)算法。 每個(gè)進(jìn)程有一個(gè)進(jìn)程控制塊（PCB）表示。進(jìn)程控制塊可以包含如下信息：進(jìn)程名、優(yōu)先數(shù)、到達(dá)時(shí)間、需要運(yùn)行時(shí)間、已用CPU時(shí)間、進(jìn)程狀態(tài)等等。 進(jìn)程的優(yōu)先數(shù)及需要的運(yùn)行時(shí)間可以事先人為地指定（也可以由隨機(jī)數(shù)產(chǎn)生）。進(jìn)程的到達(dá)時(shí)間為輸入進(jìn)程的時(shí)間。 進(jìn)程的運(yùn)行時(shí)間以時(shí)間片為單位進(jìn)行計(jì)算。 每個(gè)進(jìn)程的狀態(tài)可以是就緒 W（Wait）、運(yùn)行R（Run）、或完成F（Finish）三種狀態(tài)之一。 就緒進(jìn)程獲得 CPU后都只能運(yùn)行一個(gè)時(shí)間片。用已占用CPU時(shí)間加1來表示。 如果運(yùn)行一個(gè)時(shí)間片后，進(jìn)程的已占用 CPU時(shí)間已達(dá)到所需要的運(yùn)行時(shí)間，則撤消該進(jìn)程，如果運(yùn)行一個(gè)時(shí)間片后進(jìn)程的已占用CPU時(shí)間還未達(dá)所需要的運(yùn)行時(shí)間，也就是進(jìn)程還需要繼續(xù)運(yùn)行，此時(shí)應(yīng)將進(jìn)程的優(yōu)先數(shù)減1（即降低一級(jí)），然后把它插入就緒隊(duì)列等待CPU。 每進(jìn)行一次調(diào)度程序都打印一次運(yùn)行進(jìn)程、就緒隊(duì)列、以及各個(gè)進(jìn)程的 PCB，以便進(jìn)行檢查。 重復(fù)以上過程，直到所要進(jìn)程都完成為止

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.
