The LPC2292/2294 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 pct with minimal performance penalty. With their 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, 2/4 (LPC2294) advanced CAN channels, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications as well as medical systems and fault-tolerant maintenance buses. The number of available fast GPIOs ranges from 76 (with external memory) through 112 (single-chip). With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as many other general-purpose applications. Remark: Throughout the data sheet, the term LPC2292/2294 will apply to devices with and without the /00 or /01 suffix. The suffixes /00 and /01 will be used to differentiate from other devices only when necessary.

We propose and analyze several timestamping of an MPEG-2 Transport Stream transmitted strategies for performing over a packet-switched network using the PCR-unaware encapsulation scheme, and analyze their effect on the quality of the recovered clock at the MPEG-2 Systems decoder.

In most software-development organizations, the testing program functions as the final "quality gate" for an application, allowing or preventing the move from the comfort of the software-engineering environment into the real world. With this role comes a large responsibility: The success of an application, and possibly of theorganization, can rest on the quality of the software product.

You may have heard the Latest Brief web service on CodeProject.com. It provides several methods for web client programs to retrieve information about CodeProject.com, such as the latest article updates, the latest comments, and the latest lounge posts, etc. Some very popular articles on the CodeProject site make use of this service. In this article, I am going to present a java client program that uses soap message to call the methods of this web service. My program is not a general java soap client, which means you cannot use it to call other web services directly. However, you can easily modify it for other web services. The program uses only basic Java, it does not depend on any other external class library.

第一節、samba是干什么的？它有什么用？ Samba（SMB是其縮寫） 是一個網絡服務器，它是Linux作為本地服務器最重要的一個服務，用于Linux和Windows共享文件之用；Samba可以用于Windows和 Linux之間的共享文件，也一樣用于Linux和Linux之間的共享文件；不過對于Linux和Linux之間共享文件有更好的網絡文件系統 NFS，NFS也是需要架設服務器的； 2、安裝及服務操作命令 安裝samba程序非常簡單，使用rpm -q samba查看當前系統是否已經安裝了samba軟件。 如果沒有那就進入光盤，rpm -ivh *samba*.rpm即可。 仔細說下安裝的包： samba-common-3.0.28-0.el5.8 //samba服務器和客戶端中的最基本文件 samba-3.0.28-0.el5.8 //samba服務器核心軟件包 system-config-samba-1.2.39-1.el5 //samba圖形配置界面 samba-client-3.0.28-0.el5.8 //samba客戶端軟件 啟動、暫停和停止服務： /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 第二節、由最簡單的一個例子說起，匿名用戶可讀可寫的實現 第一步： 更改smb.conf 我們來實現一個最簡單的功能，讓所有用戶可以讀寫一個Samba 服務器共享的一個文件夾；我們要改動一下smb.conf ；首先您要備份一下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 & 然后我們把下面這段寫入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]這段是全局配置，是必段寫的。其中有如下的幾行； workgroup 就是Windows中顯示的工作組；在這里我設置的是WORKGROUP （用大寫）； netbios name 就是在Windows中顯示出來的計算機名； server string 就是Samba服務器說明，可以自己來定義；這個不是什么重要的； security 這是驗證和登錄方式，這里我們用了share ；驗證方式有好多種，這是其中一種；另外一種常用的是user的驗證方式；如果用share呢，就是不用設置用戶和密碼了； [test] 這個在Windows中顯示出來是共享的目錄； path = 可以設置要共享的目錄放在哪里； writeable 是否可寫，這里我設置為可寫； browseable 是否可以瀏覽，可以；可以瀏覽意味著，我們在工作組下能看到共享文件夾。如果您不想顯示出來，那就設置為 browseable=no，guest ok 匿名用戶以guest身份是登錄； 第二步：建立相應目錄并授權 [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 注釋：關于授權nobody，我們先用id命令查看了nobody用戶的信息，發現他的用戶組也是nobody，我們要以這個為準。有些系統nobody用戶組并非是nobody ； 第三步：啟動服務器 第四步：訪問Samba 服務器的共享； 1、在Linux 中您可以用下面的命令來訪問； [root@localhost ~]# smbclient -L //liukai或 smbclient //192.168.0.94/test Password: 注：直接按回車 2、在Windows中，您可以用下面的辦法來訪問； \\liukai 或 \\192.168.0.94 3、說明：如果用了netbiosname，就可以用“\\主機名”來訪問，如果沒用netbiosname，就不能用主機名訪問。 第三節、簡單的密碼驗證服務器 修改smb.conf文件： security = user guest account = liukai encrypt passwords = yes smb passwd file = /etc/samba/smbpasswd 然后，建立一個新用戶 useradd liukai passwd liukai 成功后，cat /etc/passwd | mksmbpasswd.sh > /etc/samba/smbpasswd smbpasswd -a liukai 這就成功地添加了一個smb用戶。 重啟服務，使用這個用戶進行登錄即可。

Use the fast Fourier transform function fft to analyse following signal. Plot the original signal, and the magnitude of its spectrum linearly and logarithmically. Apply Hamming window to reduce the leakage. . The hamming window can be coded in Matlab as for n=1:N hamming(n)=0.54+0.46*cos((2*n-N+1)*pi/N); end; where N is the data length in the FFT.

Mobile communication devices like smart phones or tablet PCs enable us to consume information at every location and at every time. The rapid development of new applications and new services and the demand to access data in real time create an increasing throughput demand. The data have to be transmitted reliably to ensure the desired quality of service. Furthermore, an improved utilization of the bandwidth is desired to reduce the cost of transmission.

With the rapid growth in the number of wireless applications, services and devices, using a single wireless technology such as a second generation (2G) and third gener- ation (3G) wireless system would not be efficient to deliver high speed data rate and quality-of-service (QoS) support to mobile users in a seamless way. The next genera- tion wireless systems (also sometimes referred to as Fourth generation (4G) systems) are being devised with the vision of heterogeneity in which a mobile user/device will be able to connect to multiple wireless networks (e.g., WLAN, cellular, WMAN) simultaneously.
