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!

處理機調度,編寫一個進程調度程序,允許多個進程共行的進程調度程序。 進程調度算法:采用最高優先數優先的調度算法(即把處理機分配給優先數最高的進程)和先來先服務算法。 每個進程有一個進程控制塊(PCB)表示。進程控制塊可以包含如下信息:進程名、優先數、到達時間、需要運行時間、已用CPU時間、進程狀態等等。 進程的優先數及需要的運行時間可以事先人為地指定(也可以由隨機數產生)。進程的到達時間為輸入進程的時間。 進程的運行時間以時間片為單位進行計算。 每個進程的狀態可以是就緒 W(Wait)、運行R(Run)、或完成F(Finish)三種狀態之一。 就緒進程獲得 CPU后都只能運行一個時間片。用已占用CPU時間加1來表示。 如果運行一個時間片后,進程的已占用 CPU時間已達到所需要的運行時間,則撤消該進程,如果運行一個時間片后進程的已占用CPU時間還未達所需要的運行時間,也就是進程還需要繼續運行,此時應將進程的優先數減1(即降低一級),然后把它插入就緒隊列等待CPU。 每進行一次調度程序都打印一次運行進程、就緒隊列、以及各個進程的 PCB,以便進行檢查。 重復以上過程,直到所要進程都完成為止

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.
