FLASH+SwiftMP3波形同步播放器模型 功能说明:FLASH+SwiftMP3波形同步的原理其实很简单,SwiftMP3把MP3转换成SWF的时候,把mp3中的音频数据以变量s0、s1、s2、s3、……、s17共18个变量储存,然后我们就可以根据这些变量的值即时设置波谱柱的高度了。注意我只是提供一个模型,解决了主要的技术内核,但这个播放器离实际应用还有一段距离,需要你自己去完善。 使用方法: 1,用SwiftMP3转换音乐后,请在flash_boXing.xml文件中修改你的音乐名字和路径,我设置最多为三条音乐,当然,相信聪明的你有了源文件,一定能自己随便改:)。 2,“SwiftMP3-1.0”文件夹中是用来转换MP3音乐的工具,你必须注册,不然每次只能转换一小段。 特别鸣谢sxl001 ,参考教程: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.
