The injection is administered into the gluteus medius muscle, or into the gluteus minimus muscle located underneath.The injection can be administered with the patient either in the supine or lateral position. Anatomical landmarks are (1) the greater trochanter, (2) the anterior iliac spine, and (3) the iliac crest. These are eas-ily palpable bony landmarks.To locate the injection site, spread the index and middle fingers apart as far as possible. Palpate the anterior iliac spine with the tip of the index or middle finger located ventrally (depending on the side of the body). Palpate the iliac crest with the other (abducted) finger. Then rotate this finger approx. 2 cm downward, while the other finger remains on the anterior iliac spine. As a result of the rotation, the ball of the hand should rest on the great trochanter. The lower part of the triangle now formed by the index and middle fingers is the injection site.Disinfect the injection site and insert the needle perpendicularly, i.e. at a 90° angle to the body surface. Before injecting, aspirate by pulling back on the plunger of the syringe to avoid inadvertent vessel punc-turing. Now start injecting, making sure that the needle is protected against any change of position. When finished, remove the needle and compress the injection site with a sterile pad.3.2.2 Disinfection of the skinPlease use only normal tap water to disinfect the skin, since ordinary disinfectants may damage the materials of the model.4. Operation & storage4.1 Tabletop operationPosition the injection simulator on a level and non-slippery surface.4.2 Storage• The injection simulator is best stored at a dry place at room temperature.• Do not expose the injection simulator to direct sunlight, since heat over 45°C may cause the material to deform or become brittle.• When the injection simulator is not used for a prolonged period of time, it is recommended to remove the batteries.Intramuscular Injection Simulator-Buttock7®English5. General safety precautions• Keep out of the reach of children!• Do not recharge batteries (LR6) under any circumstances! Risk of Explosion!• Empty batteries must be disposed of in accordance with the national requirements!• E nvironment: components must be disposed of in accordance with the relevant national environment regulations concerning the decommissioning and final disposal of the unit.• Recharge batteries only with a suitable charging set.• D o not use any powerful chemicals to clean the unit, since these may cause damage to the materials of the model.6. Frequently asked questions (FAQs)6.1 The battery indicator is flashing. After turning the unit on again, the indicator is off. But why does it then light up again?This may happen when batteries of different capacities are used. In this case, please replace the batteries with new ones. Tip: As a rule, only use batteries of the same type, the same capacity, the same age and the same manufacturer. Mark “matching” batteries accordingly.6.2 Why can’t the injection simulator be turned on again after prolonged storage?Rechargeable batteries are subject to self-discharge, even while the unit is turned off. Self-discharge is approximately 20% per month. Even disposable batteries run down slightly while the injection simulator is turned off. Tip: Remove the batteries from the battery compartment when not using the unit for a prolonged period of time. This is to prevent that any leaking batteries cause damage to the unit. Afterthe injection simulator has not been used for a prolonged period of time, only insert freshly recharged batteries or new batteries into the unit.6.3 Which types of batteries are recommended for the injection simulator?We recommend the use of alkaline manganese batteries (type AA batteries or LR6). Zinc carbon batteries should not be used.6.4 Can I also operate the injection simulator with rechargeable batteries?Yes, you can use Ni-MH (nickel metal hydride) or Ni-Cd (nickel cadmium) rechargeable batteries.You will achieve a substantially longer operation time with Ni-MH batteries than with Ni-Cd batteries. Tip: Use batteries of the same type, age and manufacturer only.7. Transport and packagingPlease check the shipping and product packaging for any damage. In case of transport damage, please contact your dealer. Please keep the original packaging. This special packaging is the best protection for your valuable product during transport.8. Maintenance8.1 Care instructionsThe silicone skin of the injection simulator can be cleaned with a mild soap solution. Please do not use any detergents containing solvents, as these will damage the silicone skin.8.2. Exchanging the silicone skinLift the silicone skin up on one side of the injection simulator and then pull it up on the left and the right until it is completely detached from the frame (see p. 9/figs. 4 + 5).Attention: Please make sure that the (foam) muscle is not detached from the underlying bone during this process. The silicone skin can now be easily removed and exchanged with a replacement skin (see p. 10/figs. 6 ). The old silicone skin can be disposed of with normal household waste.

1-Torque1.5中文教程

Torque 1.5 – 介绍教程欢迎来到Torque的世界祝贺你买了我们的Torque 游戏引擎。

这个教程会带领你参观大部分Torque的基本功能，也是你开始自己做游戏的一个起点。

做完这个教程时，我们已经做好了一个简单的3D游戏！在我们进入Torque世界以前，有两点值得注意。

在这个教程中，当你看到诸如“Select File > Open Mission”，它意味着点击File菜单中的“Open Mission”选项。

至于文件的位置，我们假定你把Torque安装在了某个硬盘根目录的/Torque/SDK目录。

第2点，这个教程是写给PC平台用户的，如果你使用的是苹果系统，我们强烈建议你使用两个按键的鼠标，同时用Option键代替Ctrl键的操作。

另外，应用程序文件在Mac中被叫做“二进制文件”的，我们在这里叫“可执行文件”。

开始页在Torque/SDK/example目录下，你会发现名为torqueDemo可执行文件。

当你运行torqueDemo的时候，你会发现如下的开始页面：那顶上的一群图标是到TGE工具和文档的快捷方式。

GUIEditor是制作图形用户界面的工具。

World Editor是创造你的游戏世界并添加物体。

Console是提供通过文字界面访问和控制游戏引擎的脚本。

在这个教程中，我们将要探索GUI和World编辑器，并且我们会快速浏览一下Console。

至于TDN，News，Docs，和Forums图标是关于Torque信息的网页的链接。

Tutorial是本教程的链接。

Options让你能设置普通的图形和声音选项，比如屏幕分辨率或音量等。

最后，Exit 就像你想象中的那样，退出这个引擎。

我们在这个教程中不会深入介绍Torque 的Consol （控制台），只是让你知道它能做什么，点击这个图标，在Consol 窗口你可以看到引擎启动后的一些进程记录。

你不仅仅可以用它来得到文字反馈，你也能直接在文字输入框中输入命令，举个例子，输入“quit();”，当然，这个命令退出了TGE 。

Nutch 的配置文件

Nutch 的配置Nutch的配置文件主要有三类：1.Hadoop的配置文件，Hadoop-default.xml和Hadoop-site.xml。

2.Nutch的配置文件，Nutch-default.xml和Nutch-site.xml。

3.Nutch的插件的配置文件，这些插件的配置文件在加载插件的时候由插件自行加载，如filter的配置文件。

配置文件的加载顺序决定了配置文件的优先级，先加载的配置文件优先级低，后加载的配置文件优先级高，优先级低的配置会被优先级高的配置覆盖。

因此，了解Nutch配置文件加载的顺序对学习使用Nutch是非常必要的。

下面我们通过对Nutch源代码的分析来看看Nutch加载配置文件的过程。

Nutch1.0使用入门（一）介绍了Nutch主要命令--crawl的使用，下面我们就从crawl的main类（org.apache.nutch.crawl.Crawl)的main方法开始分析：Crawl类main方法中加载配置文件的源码如下：Configuration conf = NutchConfiguration.create();conf.addResource("crawl-tool.xml");JobConf job = new NutchJob(conf);上面代码中，生成了一个NutchConfiguration类的对象，NutchConfiguration 是Nutch管理自己配置文件的类，Configuration是Hadoop管理自己配置文件的类。

下面我们进入NutchConfiguration类的create()方法。

/** Create a {@link Configuration} for Nutch. */public static Configuration create() {Configuration conf = new Configuration();addNutchResources(conf);return conf;}create()方法中，先生成了一个Configuration类的对象。

nuttcp 使用方法

nuttcp 使用方法一、什么是 nuttcp？nuttcp 是一款用于测试网络带宽的工具，它通过在客户端和服务器之间传输数据来测量网络的性能和吞吐量。

nuttcp 支持多种操作系统，包括 Linux、Windows 和 macOS。

它是一个命令行工具，使用简单且功能强大。

二、安装 nuttcp1. 在 Linux 上安装 nuttcp在大多数 Linux 发行版中，nuttcp 可以通过包管理器进行安装。

例如，在Ubuntu 上，可以使用以下命令安装 nuttcp：sudo apt-get install nuttcp2. 在 Windows 上安装 nuttcp在 Windows 上，可以从 nuttcp 的官方网站（）下载预编译的二进制文件。

解压缩下载的文件后，将 nuttcp.exe 添加到系统的 PATH 环境变量中，这样就可以在命令提示符中直接运行 nuttcp。

3. 在 macOS 上安装 nuttcp在 macOS 上，可以使用 Homebrew 包管理器来安装 nuttcp。

打开终端，并执行以下命令：brew install nuttcp三、使用 nuttcp 进行带宽测试1. 在服务器端启动 nuttcp在服务器上，打开终端并执行以下命令以启动 nuttcp 服务器：nuttcp -S这将启动一个 nuttcp 服务器，并监听默认端口 5001。

如果你想使用其他端口，可以使用-p参数指定。

2. 在客户端执行带宽测试在客户端上，打开终端并执行以下命令以执行带宽测试：nuttcp <服务器IP地址>替换<服务器IP地址>为实际的服务器 IP 地址。

默认情况下，nuttcp 将使用默认端口 5001 进行测试。

如果服务器使用了其他端口，可以使用-p参数指定。

3. 查看测试结果带宽测试完成后，nuttcp 将显示测试的结果。

其中包括平均传输速度、传输的数据量、传输时间等信息。

nutch介绍

搜索过程 Nutch提供了一个Fascade的NutchBean类供我们使用，一段典型的代码如下
nutch的目标 nutch致力于让每个人能很容易, 同时花费很少就可以配置世界一流的Web搜索引擎. 为了完成这一宏伟的目标, nutch必须能够做到: • 每个月取几十亿网页 • 为这些网页维护一个索引 • 对索引文件进行每秒上千次的搜索 • 提供高质量的搜索结果 • 以最小的成本运作这将是一个巨大的挑战。
Crawler工作流程 1. 创建一个新的WebDb (admin db -create). 2. 将抓取起始URLs写入WebDB中 (inject). 3. 根据WebDB生成fetchlist并写入相应的 segment(generate). 4. 根据fetchlist中的URL抓取网页 (fetch). 5. 根据抓取网页更新WebDb (updatedb).
爬虫，Crawler Index是Crawler抓取的所有网页的索引，它是通过对所有单个segment中的索引进行合并处理所得的。Nutch利用Lucene技术进行索引，所以Lucene中对索引进行操作的接口对Nutch中的 index同样有效。但是需要注意的是，Lucene中的segment和Nutch中的不同，Lucene中的 segment是索引index的一部分，但是Nutch中的 segment只是WebDB中各个部分网页的内容和索引，最后通过其生成的index跟这些segment已经毫无关系了。
爬虫，Crawler Crawler的重点在两个方面，Crawler的工作流程和涉及的数据文件的格式和含义。数据文件主要包括三类，分别是web database，一系列的 segment加上index，三者的物理文件分别存储在爬行结果目录下的db目录下webdb子文件夹内， segments文件夹和index文件夹。那么三者分别存储的信息是什么目录： 1.crawdb,linkdb 是web link目录，存放url 及url的互联关系，作为爬行与重新爬行的依据，页面默认30天过期。 2.segments 是主目录，存放抓回来的网页。页面内容有 bytes[]的raw content 和 parsed text的形式。nutch 以广度优先的原则来爬行，因此每爬完一轮会生成一个 segment目录。 3.index 是lucene的索引目录，是indexs里所有index合并后的完整索引，注意索引文件只对页面内容进行索引，没有进行存储，因此查询时要去访问segments目录才能获得页面内容。

NUTS软件的使用说明

NUTS软件的使用说明核磁共振数据的处理主要包括以下几步：1．FT变换（将FID数据转换成通常的频率域图谱）2．谱峰调相位3．谱图基线校正4．化学位移定标5．谱图积分6．作图下面就这些步骤中最基本的内容作简单介绍，详细的说明请查阅该程序的ONLINE HELP.1，谱图转换启动NUTS软件，打开文件夹，在你的PC机上找到核磁数据目录，从该目录或它的子目录中找到名为fid的文件，打开该文件时会出现一对话框：Want to try an Auto Detect Import? 选择“是”，屏幕上出现FID信号，键入FT，将FID信号转变为谱图。

2．调相位(AP)键入ZO或双击左键选择左侧一段（一般是谱图的最左侧）后键入1，再选择右侧一段（一般是谱图的最右侧）后键入2，回车，键入PE，揿住鼠标左键将左侧基线调平，再单击右键，然后揿住右键将右侧基线调平，回车。

也可以通过键入PH，或用光标点击PH图标，按住mouse左键，左右移动mouse,可调谱的零级相位，同样方式，右键可调谱的一级相位，相位调好后回车，退出调相位功能。

3．基线校正键入BC，BF，自动基线校正；对于高版本可以直接键入FBLP自动基线校正。

4．定标按住mouse左键，出一红色“十”光标，将光标移至要定标的TMS或溶剂峰处，使竖线与峰重叠，同时打“O”，出一对话框，输入TMS或溶剂峰的化学位移数值，然后点击OK即可，比如在CDCl3作溶剂时键入O在对话框中键入7.26然后点击OK即可。

5．积分键入AI或用光标点击“AI”图标，对谱图做自动分段积分，如要调积分线相位，则键入“ID”，再键入“B”，类似于调谱图相位，按住mouse左键或右键，左右移动mouse可分别调积分线的零级或一级相位，完成后回车，退出ID功能。

如对某一处分段积分不满意，要重新分段，可按一下mouse左键，屏幕上出现一红色竖线，将此线移至不满意的积分线处，打“D”，原来的积分线消失，再按一下左键，将红线移至要积分的峰的左侧，按一下左键，再移至峰的右侧，再按一下左键，就完成了对这组峰的积分，全部完成后回车，退出积分功能。

nutch应用-安装与使用

nutch应用-安装与使用Nutch 使用之锋芒初试“工欲善其事，必先利其器。

”经过前文的“细解”，我们已经完成了Nutch在Windows中的安装。

接下来就让我们通过锋芒初试，来亲自体验一下Nutch的强大功能吧！Nutch的爬虫抓取网页有两种方式，一种方式是Intranet Crawling，针对的是企业内部网或少量网站，使用的是crawl命令；另一种方式是Whole-web crawling，针对的是整个互联网，使用inject、generate、fetch和updatedb等更底层的命令。

本文将以使用Nutch为笔者在CSDN处的个人专栏(/zjzcl)文章内容建立搜索功能为例，来讲述Intranet Crawling的基本使用方法（假设用户电脑系统已安装好JDK、Tomcat和Resin，并做过相应的环境配置）。

1、设置Nutch的环境变量在Windows系统的环境变量设置中，增加NUTCH_JAVA_HOME变量，并将其值设为JDK的安装目录。

比如笔者电脑中JDK安装于D:\j2sdk1.4.2_09，因此将NUTCH_JAVA_HOME的值设为D:\j2sdk1.4.2_09。

2、Nutch抓取网站页面前的准备工作（1）在Nutch的安装目录中建立一个名为url.txt的文本文件，文件中写入要抓取网站的顶级网址，即要抓取的起始页。

笔者在此文件中写入如下内容：/zjzcl（2）编辑conf/crawl-urlfilter.txt文件，修改部分:# accept hosts in +^/zjzcl3、运行Crawl命令抓取网站内容双击电脑桌面上的Cygwin图标，在命令行窗口中输入：cd /cygdrive/i/nutch-0.7.1不明白此命令含义的读者请参见前《细解》一文，然后再输入：bin/nutch crawl url.txt -dir crawled -depth 3 -threads 4 >& crawl.log等待大约2分多钟后，程序运行结束。

nutch(windows7环境下的配置)

经过好几天的尝试，终于成功在windows7的环境下将nutch成功运行出来了，下面将经验记下。

1、cygwin的安装：下载地址：/setup.exe（1）因为nutch自身的命令是要在linux环境下才能运行，所以先安装了cygwin，Cygwin 是一个在Windows下的模拟Linux系统程序。

Cygwin的安装：/cfree_ch/doc/help/UsingCF/CompilerSupport/Cygwin/Cygwin1 .htm这个网址对cygwin的安装步骤演示的很详细，对我们这些初步接触cygwin的人有很大的帮助。

（2）下面是我自己安装时的截图1）安装页面，点击下一步2）选择安装目录，可以根据默认，也可以根据自己需要换路径3）建立Downloads文件夹，接收下载包4）选择镜像地址，没有演示中说的：。

.cn代表中国的网站，下载会更快5）选择安装包6）安装完成2、下载安装apache-nutch-1.2-bin.zip并设置。

下载地址：/dist/nutch/（1）下载完成后将其解压到D盘，文件夹名为nutch-1.2（2）输入，打开到d盘目录下nutch-1.2文件夹，输入bin/nutch 进行nutch安装测试：出来一系列nutch的命令，证明nutch安装成功；（3）在Windows系统的环境变量设置中，添加NUTCH_JA V A_HOME环境变量：D:\jdk1.7.0_07。

并将其值设为JDK的安装目录。

（4）Nutch抓取网站页面前的预备工作1）在Nutch-1.2的安装目录下建立一个名为urls的文件夹，并在文件夹下建立url.text 文件,在文件中写入：（即要抓取网站的网址）2）)修改网址过滤规则，编辑conf/crawl-urlfilter.txt文件，修改部分:3）修改conf/nutch-site.xml代理信息，在<configuration>和</configuration>之间添加如下内容4）修改nutch-1.2\conf\nutch-default.xml文件，找<name></name> ，然后随便设置Value值注意：如果为空时，在爬行的时候可能出现空指针异常且在tomcat 中搜索时可能导致0条记录，所以务必加上。

nutch的基本工作流程理解

今天研究了Nutch，差不多已经好几个小时了，到现在还没有搞定，也这么晚了，先记录下来，明天继续吧。

一开始很多时间都浪费在了cygwin的安装上了，bs这个软件的开发者了，一个不伦不类的软件安装程序，安装的时候还要从网上下载东东。

不过最后终于装成功了，先下载到本地后，再安装的（建议下载站点中选 TW 的比较块）。

下面是我安装CYGWIN和NUTCH的过程，都块成功了，但最后卡在了用户查询界面，输入东西什么都查不出来，不知怎么回事。

NUTCH的大致原理如下：安装步骤参考了该文章一、环境：1.操作系统：windowsXp,windows2000+2.javaVM：java1.5.x，设置JAVA_HOME到环境变量3.cygwin,当然这个不是必需的，只是nutch提供的脚本只能在shell环境下使用，所以使用cygwin来虚拟shell命令。

4.nutch版本：0.85.tomcat：5.0二、cygwin的安装：cygwin的安装在Nutch在Windows中安装之细解一文中有较为详细的介绍，此处不再介绍安装步骤，只介绍安装后需要如何判断是否能够使用：在cygwin 的安装目录下，查找x:\cygwin\cygwin\bin\sh.exe，存在此命令即可使用。

cygwin在删除后会发现无法再次成功安装的问题，可以通过注册表内的查找功能，删除所有包含cygwin内容的键值即可。

三、nutch的安装和配置：1。

从/nutch/release/下载0.8或更高的版本，解压缩后，放置到cygwin的根目录下，如图：图中可以看到nutch目录在cygwin的根目录下。

2。

在nutch/bin下，建立urls目录，然后建立一个url.txt文件，在url.txt 文件内写入一个希望爬行的url，例如：，目录结构如图：3。

打开nutch\conf\crawl-urlfilter.txt文件，把字符替换为url.txt内的url的域名，其实更简单点，直接删除这几个字就可以了，也就是说，只保存+^http://([a-z0-9]*\.)*这几个字就可以了，表示所有http的网站都同意爬行。

2.2 回零机床正常启动后，需要回零后才能执行程序的自动加工。

当系统处于空闲状态下，回零操作可以通过以下两种方式实现：1、单轴回零2、全部回零2.2.1 单轴回零1、开机后系统处于空闲状态；2、点击主界面上的回零按钮，则操作面板上的（循环启动）按钮灯长亮；3、按下（循环启动）按钮后，相应的轴开始回零；4、回零完成后，主界面对应轴的回零按钮消失。

2.2.2 全部回零1、开机后系统处于空闲状态；2、按下操作面板上的（回零）按钮，该按钮灯长亮，同时（循环启动）按钮灯长亮；3、按下（循环启动）按钮后，所有轴开始回零；4、回零完成后，主界面上的回零按钮消失。

nutch使用

文章参考：/author/kingjiang/46b679e96d46441f97e0aa221ac0372f.html修改：孙建凯总体上Nutch可以分为2个部分：抓取部分和搜索部分。

抓取程序抓取页面并把抓取回来的数据做成反向索引，搜索程序则对反向索引搜索回答用户的请求。

抓取程序和搜索程序的接口是索引。

两者都使用索引中的字段。

实际上搜索程序和抓取程序可以分别位于不同的机器上。

网页的抓取主要分为2种：Intranet crawling和Whole-web crawling。

从名字可以很容易明白他们抓取的范围。

一般Whole-web crawling对配置要求高（面对海量数据，抓取数据和存储空间都至关重要），花费时间长（几天甚至是几周），我们没有必要做这样的测试。

所以我已抓取我们学校内部网页为例子，来做一个测试。

抓取前的准备工作输入需要抓取的网站地址在Nutch的安装目录中建立一个名为myurl的文本文件，文件中写入要抓取网站的顶级网址，即要抓取的起始页。

以我要抓取的网页为例，输入：/注意：最后一个“/”不能少，否则和conf/crawl-urlfilter.txt中的内容不匹配，不能运行,http好像也不能少。

更改配置文件crawl-urlfilter.txt编辑conf/crawl-urlfilter.txt文件，修改部分，把它替换为你想要抓取的域名（地址），即把#accept hosts in +^http://([a-z0-9]*\.)*/修改为：#accept hosts in +^http://([a-z0-9]*\.)*/编辑nutch-1.2\conf\nutch-site.xmlnutch-default.xml里属性默认为空，所以必须在nutch-site.xml中为该属性设值，否则会出错(程序抓取页面时，会判断该属性是否为空，如果为空的话会停止抓取)。

因此可类似作如下设置<configuration><property><name></name><value>ir.sdu</value>//这里的内容可以是任意的</property></configuration>运行crawl命令抓取网站内容做好抓取前的准备，接着就可以使用crawl命令抓取网页。
