There are _NO_ standard sample rate for the samples used in modules. But most often the samples are done on the rate called C-3 (which is about 16574 Hz if you have a PAL machine). Sometimes drums are sampled at A-3 (around 28 kHz), and some sounds are at ~8 kHz or anything else to save space.

The purpose of this project is to explore the issues and implementation of a multiple instruction stream, single data stream processor. We are running two instruction streams on two CPUs which share an address space. The processors share a second level cache, and maintain coherence at the L1 cache with a write-invalidate policy. The L2 cache is two-way set associative, with a block size of 8 words, and a total capacity of 512 words.

(有源代碼)數值分析作業,本文主要包括兩個部分,第一部分是常微分方程(ODE)的三個實驗題,第二部分是有關的拓展討論,包括高階常微分的求解和邊值問題的求解(BVP).文中的算法和算例都是基于Matlab計算的.ODE問題從剛性(STIFFNESS)來看分為非剛性的問題和剛性的問題,剛性問題(如大系數的VDP方程)用通常的方法如ODE45來求解,效率會很低,用ODE15S等,則效率會高多了.而通常的非剛性問題,用ODE45來求解會有很好的效果.從階次來看可以分為高階微分方程和一階常微分方程,高階的微分方程一般可以化為狀態空間(STATE SPACE)的低階微分方程來求解.從微分方程的性態看來,主要是微分方程式一階導系數大的時候,步長應該選得響應的小些.或者如果問題的性態不是太好估計的話,用較小的步長是比較好的,此外的話Adams多步法在小步長的時候效率比R-K(RUNGE-KUTTA)方法要好些,而精度也高些,但是穩定區間要小些.從初值和邊值來看,也是顯著的不同的.此外對于非線性常微分方程還有打靶法,胞映射方法等.而對于微分方程穩定性的研究,則諸如相平面圖等也是不可缺少的工具.值得提出的是,除了用ode系類函數外,用simulink等等模塊圖來求解微分方程也是一種非常不錯的方法,甚至是更有優勢的方法(在應用的角度來說).

Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were specifically designed for servo amplifiers. Today a class of motors is designed for applica-tions that may use a servo amplifier or a variable-frequency controller, which means that a motor may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motor a servo system, so it is possible for a simple AC induction motor that is connected to a velocity controller to be called a servomotor.

FLASH+SwiftMP3波形同步播放器模型 功能說明：FLASH+SwiftMP3波形同步的原理其實很簡單，SwiftMP3把MP3轉換成SWF的時候，把mp3中的音頻數據以變量s0、s1、s2、s3、……、s17共18個變量儲存，然后我們就可以根據這些變量的值即時設置波譜柱的高度了。注意我只是提供一個模型，解決了主要的技術內核，但這個播放器離實際應用還有一段距離，需要你自己去完善。 使用方法： 1，用SwiftMP3轉換音樂后，請在flash_boXing.xml文件中修改你的音樂名字和路徑，我設置最多為三條音樂，當然，相信聰明的你有了源文件，一定能自己隨便改：）。 2，“SwiftMP3-1.0”文件夾中是用來轉換MP3音樂的工具，你必須注冊，不然每次只能轉換一小段。 特別鳴謝sxl001 ，參考教程：http://space.flash8.net/bbs/thread-307160-1-1.html

Huffman codes 1.In telecommunication, how do we represent a set of messages, each with an access frequency, by a sequence of 0 s and 1 s? 2.To minimize the transmission and decoding costs, we may use short strings to represent more frequently used messages. 3.This problem can be solved by using an extended binary tree which is used in the 2-way merging problem. the sourse code is to encode and decode the Huffman.
