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

Sensing and planning are at the core of robot motion. Traditionally, mobile robots have been used for performing various tasks with a general-purpose processor on-board. This book grew out of our research enquiry into alternate architectures for sensor-based robot motion. It describes our research starting early 2002 with the objectives of obtaining a time, space and energy-efficient solution for processing sensor data for various robotic tasks. New algorithms and architectures have been developed for exploration and other aspects of robot motion. The research has also resulted in design and fabrication of an FPGA-based mobile robot equipped with ultrasonic sensors. Numerous experiments with the FPGA-based mobile robot have also been performed and they confirm the efficacy of the alternate architecture.

This code proposes genetic algorithm (GA) to optimize the point-to-point trajectory planning for a 3-link robot arm. The objective function for the proposed GA is to minimizing traveling time and space, while not exceeding a maximum pre-defined torque, without collision with any obstacle in the robot workspace.

The code performs a number (ITERS) of iterations of the Bailey s 6-step FFT algorithm (following the ideas in the CMU Task parallel suite). 1.- Generates an input signal vector (dgen) with size n=n1xn2 stored in row major order In this code the size of the input signal is NN=NxN (n=NN, n1=n2=N) 2.- Transpose (tpose) A to have it stored in column major order 3.- Perform independent FFTs on the rows (cffts) 4.- Scale each element of the resulting array by a factor of w[n]**(p*q) 5.- Transpose (tpose) to prepair it for the next step 6.- Perform independent FFTs on the rows (cffts) 7.- Transpose the resulting matrix The code requires nested Parallelism.
