A programmable digital signal processor (PDSP) is a special-purpose microprocessor with specialized architecture and instruction set for implementing DSP algorithms. Typical architectural features include multiple memory partitions (onchip, off-chip, data memory, program memory, ETC.), multiple (generally pipelined) arithmetic and logic units (ALUs), nonuniform register sets, and extensive hardware numeric support [1,2]. Single-chip PDSPs have become increasingly popular for real-time DSP applications [3,4].

Parallel robotic manipulators can be considered a well-established option for many different applications of manipulation, machining, guiding, testing, control, tracking, haptic force feed-back, ETC. A typical parallel robotic manipulator (PM) consists of a mobile platform connected to the base (fixed platform) by at least two kinematic chains called limbs. The mobile platform can achieve between one and three independent translations (T) and one to three independent rotations (R).

自主移动机器人是目前机器人发展的主流,随着其应用领域的不断扩展和自动化程度的进一步提高,对机器人的功能提出了更高的要求,特别是需要各种具有不同智能程度的机器人,能够设定自己的目标,规划并执行自己的任务动作,不断适应环境的变化。在移动机器人相关技术研究中,导航技术是其核心,而路径规划是导航技术研究的一个重要环节和组成部分。路径规划是智能移动机器人研究的核心内容之一,它起始于20世纪70年代,迄今为止,已有大量的研究成果报道[1]。大多数国内外文献将此问题称为Path Planning,Find-Path Problem, Collision-Free,Obstacle Avoidance,Motion Planning,ETC.。所谓移动机器人路径规划技术,是指移动机器人在一定的环境(通常具有障碍物)中,能够按照某种标准,如工作代价最小、行走路线最短、行走时间最短等,自行规划出一条到达指定终点的无碰路径,同时高效完成作业任务。

第一节、samba是干什么的?它有什么用? Samba(SMB是其缩写) 是一个网络服务器,它是Linux作为本地服务器最重要的一个服务,用于Linux和Windows共享文件之用;Samba可以用于Windows和 Linux之间的共享文件,也一样用于Linux和Linux之间的共享文件;不过对于Linux和Linux之间共享文件有更好的网络文件系统 NFS,NFS也是需要架设服务器的; 2、安装及服务操作命令 安装samba程序非常简单,使用rpm -q samba查看当前系统是否已经安装了samba软件。 如果没有那就进入光盘,rpm -ivh *samba*.rpm即可。 仔细说下安装的包: samba-common-3.0.28-0.el5.8 //samba服务器和客户端中的最基本文件 samba-3.0.28-0.el5.8 //samba服务器核心软件包 system-config-samba-1.2.39-1.el5 //samba图形配置界面 samba-client-3.0.28-0.el5.8 //samba客户端软件 启动、暂停和停止服务: /ETC/init.d/smb start /ETC/init.d/smb stop /ETC/init.d/smb restart 或 service smb start service smb stop service smb restart 第二节、由最简单的一个例子说起,匿名用户可读可写的实现 第一步: 更改smb.conf 我们来实现一个最简单的功能,让所有用户可以读写一个Samba 服务器共享的一个文件夹;我们要改动一下smb.conf ;首先您要备份一下smb.conf文件; [root@localhost ~]# cd /ETC/samba [root@localhost samba]# cp smb.conf smb.conf.bak [root@localhost samba]# vi smb.conf 或geidt smb.conf & 然后我们把下面这段写入smb.conf中: [global] workgroup = WORKGROUP netbios name = Liukai server string = Liukai's Samba Server security = share [test] path = /opt/test writeable = yes browseable = yes guest ok = yes 注解: [global]这段是全局配置,是必段写的。其中有如下的几行; workgroup 就是Windows中显示的工作组;在这里我设置的是WORKGROUP (用大写); netbios name 就是在Windows中显示出来的计算机名; server string 就是Samba服务器说明,可以自己来定义;这个不是什么重要的; security 这是验证和登录方式,这里我们用了share ;验证方式有好多种,这是其中一种;另外一种常用的是user的验证方式;如果用share呢,就是不用设置用户和密码了; [test] 这个在Windows中显示出来是共享的目录; path = 可以设置要共享的目录放在哪里; writeable 是否可写,这里我设置为可写; browseable 是否可以浏览,可以;可以浏览意味着,我们在工作组下能看到共享文件夹。如果您不想显示出来,那就设置为 browseable=no,guest ok 匿名用户以guest身份是登录; 第二步:建立相应目录并授权 [root@localhost ~]# mkdir -p /opt/test [root@localhost ~]# id nobody uid=99(nobody) gid=99(nobody) groups=99(nobody) [root@localhost ~]# chown -R nobody:nobody /opt/test 注释:关于授权nobody,我们先用id命令查看了nobody用户的信息,发现他的用户组也是nobody,我们要以这个为准。有些系统nobody用户组并非是nobody ; 第三步:启动服务器 第四步:访问Samba 服务器的共享; 1、在Linux 中您可以用下面的命令来访问; [root@localhost ~]# smbclient -L //liukai或 smbclient //192.168.0.94/test Password: 注:直接按回车 2、在Windows中,您可以用下面的办法来访问; \\liukai 或 \\192.168.0.94 3、说明:如果用了netbiosname,就可以用“\\主机名”来访问,如果没用netbiosname,就不能用主机名访问。 第三节、简单的密码验证服务器 修改smb.conf文件: security = user guest account = liukai encrypt passwords = yes smb passwd file = /ETC/samba/smbpasswd 然后,建立一个新用户 useradd liukai passwd liukai 成功后,cat /ETC/passwd | mksmbpasswd.sh > /ETC/samba/smbpasswd smbpasswd -a liukai 这就成功地添加了一个smb用户。 重启服务,使用这个用户进行登录即可。

Free Space Optical Communication (FSOC) is an effective alternative technology to meet the Next Generation Network (NGN) demands as well as highly secured (mili- tary) communications. FSOC includes various advantages like last mile access, easy installation, free of Electro Magnetic Interference (EMI)/Electro Magnetic Compatibil- ity (EMC) and license free access ETC. In FSOC, the optical beam propagation in the turbulentatmosphereisseverelyaffectedbyvariousfactorssuspendedinthechannel, geographicallocationoftheinstallationsite,terraintypeandmeteorologicalchanges. Therefore a rigorous experimental study over a longer period becomes significant to analyze the quality and reliability of the FSOC channel and the maximum data rate that the system can operate since data transmission is completely season dependent.
