Lorem ipsum dolor sit amet是什么意思

Lorem ipsum,中文又称“乱数假文”, 是指一篇常用于排版设计领域的拉丁文文章 ,主要的目的为测试文章或文字在不同字型、版型下看起来的效果。Lorem ipsum从西元15世纪开始就被广泛地使用在西方的印刷、设计领域中,在电脑排版盛行之后,这段被传统印刷产业使用几百年的无意义文字又再度流行。由于这段文字以“Lorem ipsum”起头,并且常被用于标题的测试中,所以一般称为Lorem ipsum,简称为Lipsum。 “Lorem ipsum dolor sit amet consectetuer”出现在各种排版中.它看上去像一句睿智的拉丁习语,但实际上毫无意义.

Python 运行报错NameError出现原因,怎么解决

  python新手常见的报错提示  在运行或编写一个程序时常会遇到错误异常,这时Python会给你一个错误提示类名,告诉出现了什么样的问题(Python是面向对象语言,所以程序抛出的异常也是类)。能很好的理解这些错误提示类名所代表的意思,可以帮助你在最快的时间内找到问题所在,从而解决程序上的问题是非常有帮助的。  搜集了一些python最重要的内建异常类名,并做了简单的介绍:  AttributeError:属性错误,特性引用和赋值失败时会引发属性错误  NameError:试图访问的变量名不存在  SyntaxError:语法错误,代码形式错误  Exception:所有异常的基类,因为所有python异常类都是基类Exception的其中一员,异常都是从基类Exception继承的,并且都在exceptions模块中定义。  IOError:一般常见于打开不存在文件时会引发IOError错误,也可以解理为输出输入错误  KeyError:使用了映射中不存在的关键字(键)时引发的关键字错误  IndexError:索引错误,使用的索引不存在,常索引超出序列范围,什么是索引  TypeError:类型错误,内建操作或是函数应于在了错误类型的对象时会引发类型错误  ZeroDivisonError:除数为0,在用除法操作时,第二个参数为0时引发了该错误  ValueError:值错误,传给对象的参数类型不正确,像是给int()函数传入了字符串数据类型的参数。  1)忘记在 if , elif, else , for , while , class ,def 声明末尾添加:(导致 “SyntaxError :invalid syntax”)  该错误将发生在类似如下代码中:  if spam == 42  print("Hello!")  2)使用 = 而不是 ==(导致“SyntaxError: invalid syntax”)  = 是赋值操作符而 == 是等于比较操作。该错误发生在如下代码中:  if spam = 42:  print("Hello!")  3)错误的使用缩进量。(导致“IndentationError:unexpected indent”、“IndentationError:unindent does not match any outer indetation level”以及“IndentationError:expected an indented block”)  记住缩进增加只用在以:结束的语句之后,而之后必须恢复到之前的缩进格式。该错误发生在如下代码中:  print("Hello!")  print("Howdy!")  或者:  if spam == 42:  print("Hello!")  print("Howdy!")  或者:  if spam == 42:  print("Hello!")  4)在 for 循环语句中忘记调用 len() (导致“TypeError: "list" object cannot be interpreted as aninteger”)  通常你想要通过索引来迭代一个list或者string的元素,这需要调用 range() 函数。要记得返回len 值而不是返回这个列表。  该错误发生在如下代码中:  spam = ["cat","dog", "mouse"]  for i inrange(spam):  print(spam[i])  5)尝试修改string的值(导致“TypeError: "str" object does not support itemassignment”)  string是一种不可变的数据类型,该错误发生在如下代码中:  spam = "I have apet cat."  spam[13] = "r"  print(spam)  而你实际想要这样做:  spam = "I have apet cat."  spam = spam[:13] +"r" + spam[14:]  print(spam)  6)尝试连接非字符串值与字符串(导致 “TypeError: Can"t convert "int" object to strimplicitly”)  该错误发生在如下代码中:  numEggs = 12  print("I have " +numEggs + " eggs.")  而你实际想要这样做:  numEggs = 12  print("I have " +str(numEggs) + " eggs.")  或者:  numEggs = 12  print("I have %seggs." % (numEggs))  7)在字符串首尾忘记加引号(导致“SyntaxError: EOL while scanning string literal”)  该错误发生在如下代码中:  print(Hello!")  或者:  print("Hello!)  或者:  myName = "Al"  print("My name is "+ myName + . How are you?")  8)变量或者函数名拼写错误(导致“NameError: name "fooba" is not defined”)  该错误发生在如下代码中:  foobar = "Al"  print("My name is "+ fooba)  或者:  spam = ruond(4.2)  或者:  spam = Round(4.2)  9)方法名拼写错误(导致 “AttributeError: "str" object has no attribute"lowerr"”)  该错误发生在如下代码中:  spam = "THIS IS INLOWERCASE."  spam =spam.lowerr()  10)引用超过list最大索引(导致“IndexError: list index out of range”)  该错误发生在如下代码中:  spam = ["cat","dog", "mouse"]  print(spam[6])  11)使用不存在的字典键值(导致“KeyError:‘spam"”)  该错误发生在如下代码中:  spam = {"cat":"Zophie", "dog": "Basil", "mouse": "Whiskers"}  print("The name ofmy pet zebra is " + spam["zebra"])  12)尝试使用Python关键字作为变量名(导致“SyntaxError:invalid syntax”)  Python关键不能用作变量名,该错误发生在如下代码中:  class = "algebra"  Python3的关键字有:and, as, assert, break, class, continue, def, del, elif,else, except, False, finally, for, from, global, if, import, in, is, lambda,None, nonlocal, not, or, pass, raise, return, True, try, while, with, yield  13)在一个定义新变量中使用增值操作符(导致“NameError: name "foobar" is not defined”)  不要在声明变量时使用0或者空字符串作为初始值,这样使用自增操作符的一句spam += 1等于spam = spam + 1,这意味着spam需要指定一个有效的初始值。  该错误发生在如下代码中:  spam = 0  spam += 42  eggs += 42  14)在定义局部变量前在函数中使用局部变量(此时有与局部变量同名的全局变量存在)(导致“UnboundLocalError: local variable "foobar" referencedbefore assignment”)  在函数中使用局部变来那个而同时又存在同名全局变量时是很复杂的,使用规则是:如果在函数中定义了任何东西,如果它只是在函数中使用那它就是局部的,反之就是全局变量。  这意味着你不能在定义它之前把它当全局变量在函数中使用。  该错误发生在如下代码中:  someVar = 42  def myFunction():  print(someVar)  someVar = 100  myFunction()  15)尝试使用 range()创建整数列表(导致“TypeError: "range" object does not support itemassignment”)  有时你想要得到一个有序的整数列表,所以 range() 看上去是生成此列表的不错方式。然而,你需要记住 range() 返回的是 “range object”,而不是实际的 list 值。  该错误发生在如下代码中:  spam = range(10)  spam[4] = -1  也许这才是你想做:  spam =list(range(10))  spam[4] = -1  (注意:在 Python 2 中 spam = range(10) 是能行的,因为在 Python 2 中 range() 返回的是list值,但是在 Python 3 中就会产生以上错误)  16)不错在 ++ 或者 -- 自增自减操作符。(导致“SyntaxError: invalid syntax”)  如果你习惯于例如 C++ , Java, PHP 等其他的语言,也许你会想要尝试使用 ++ 或者 -- 自增自减一个变量。在Python中是没有这样的操作符的。  该错误发生在如下代码中:  spam = 1  spam++  也许这才是你想做的:  spam = 1  spam += 1  17)忘记为方法的第一个参数添加self参数(导致“TypeError: myMethod() takes no arguments (1 given)”)  该错误发生在如下代码中:  class Foo():  def myMethod():  print("Hello!")  a = Foo()  a.myMethod()

—Hello, Sally. How’s everything going? —__________ . A.The same to you B.Not too bad

the kings game游戏怎么玩

国王游戏源自日本的扑克牌游戏更多义项更多图片(1张)“国王游戏”起源于日本,是日本、韩国和台湾广为流行的一种多人互动游戏。在游戏中,国王的命令是绝对的,参与者需要无条件服从国王的指令,强制性规则产生的绝对权力是国王游戏令人着迷的关键。游戏尺度可由参与者通过共同认可的限制性规则自行把控,引申出多种多样的精彩玩法,给人以无限的想象空间 。可任意任命两个号码做任何事情,被抽到号码者不得违抗)。中文名:国王游戏起源地区:日本分类:互动游戏特点:国王的命令是绝对处罚方式:无限制分享游戏玩法那么,这个游戏具体该怎么玩儿呢?首先,当然是需要有一帮子人啦,一般以8-14人为宜,参与者被抽取的概率比较适中,人数太少则抽取概率太高,精神紧张,会玩儿得比较累,人数太多又造成参与度的不足,如果能男女各一半的话当然是更好啦,你懂的。然后,我们需要一副扑克牌,假设有10个人参与,就抽取出扑克牌的红桃A、2、3、4、5、6、7、8、9、10外加鬼牌一张共11张,A算做1号。洗牌后每人抽取一张做为暗牌(记住这个很关键哦,这个号码是不能给别人看到的,只能自己知道),抽到鬼牌的人要亮明鬼牌,即成为了“国王”,桌子上还剩下一张牌,这张牌即是“国王”自己的号码,是不能看的(这个很重要哦,国王们因为这张牌,自己给自己挖个大坑的大有人在哦),如果谁都没有抽到鬼牌,也就是说桌子上的那张是鬼牌,就要重新洗牌重新抽过。这样,我们的“国王”就顺利地选出来啦,“国王”可以在不看其他人数字的前提下,随意点1~10号,要求其中的2个人或3个人做任何一件事情,做什么事情由“国王”决定(注:需在参与者共同认可的限制性框架下提出命令哦,否则......),可以想出各种整人的花招。所有人必须服从“国王”的要求,因为国王不知道谁手上拿的是什么牌,所以是乱点的,不会产生针对性。同时由于“国王”自己也是有号码的,这样子“国王”的命令也有很大的可能性是由自己去完成,“国王”挖的坑越大,自己也可能摔得更惨哦。比方说:“国王”命令:2号抱起3号转5圈!这样,2号就要站出来抱起3号了哦(哼哼~~3号超重2号抱不起来可是不行的哦)

swagger ui中parameter type的类型为query是什么意思

现在多数的项目开发中,网站和移动端都需要进行数据交互和对接,这少不了使用REST编写API接口这种场景。例如我目前的工作,移动端交由了另一团队开发,不同开发小组之间就需要以规范和文档作为标准和协作基础。良好的文档可以让开发事半功倍,而作为又懒又要效率又能交代的码农,当然最希望一切自动化,或用小聪明来找到最适合的工具。Swagger-UI简单而一目了然。它能够纯碎的基于html+javascript实现,只要稍微整合一下便能成为方便的API在线测试工具。项目的设计架构中一直提倡使用TDD(测试驱动)原则来开发,swagger-ui在这方面更是能提供很大帮助。Swagger-UI更倾向于在线测试接口和数据,但其核心是一个javascript插件,只要稍作修改,便能按需求定制出不同格式的说明文档,在github上更是基于它集成到各种语言环境,分支众多。其官方提供了一个离线版本,其使用方法十分简单:直接在js格式的资源文件中录入REST API的json信息,便能容易地生成不同模块下的API列表,每个API接口描述和参数、请求方法都能在每个json数组中定制。下面是目前项目中使用到的部分预览图

Swagger2异常:Illegal DefaultValue null for parameter type integer(2.9.2版本)

对于集成Swagger(2.9.2版本,其他版本没有验证是否存在该问题),搭建Spring boot基本架构,请查看之前的文章,这里直接分析Swagger的bug SpringBoot+MyBatis搭建SSM基本骨架(Redis + Swagger+自定义配置 +mysql ) 之前测试一直用postman,直到打开 http://localhost:5088/swagger-ui.htm 才发现存在bug 一、异常分析: Illegal DefaultValue null for parameter type integer 和 NumberFormatException: For input string: "" 从上面这句可以看出,有个默认值是空字符串的变量转换成Integer类型时异常。 根据上面这句报错信息,点进去AbstractSerializableParameter.java:412可以看到 if(BaseIntegerProperty.TYPE.equals(type)){ } 就是说如果实体属性类型是Integer,就把example转为Long类型,而example默认为"",导致转换错误。 二、解决办法: 我们知道,在Swagger的浏览器界面打开的时候,对上述的默认值解析错误。一般情况下我们都省略了实体类上加@ApiModelProperty。因此解决这个问题可以在实体类中的Integer类型的属性添加注解,并给example参数赋值,且值必须为数字类型。 如果每个值都需要添加,那么会很多。 所以下面是第二种办法。我们知道报错的是at io.swagger.models.parameters.AbstractSerializableParameter.getExample(AbstractSerializableParameter.java:412) ~[swagger-models-1.5.20.jar:1.5.20] 查看pom.xml我们引用的是springfox的包,找到github项目# springfox / springfox issue查询swagger-models-1.5.20.jar,查看前面几天issue,可以发现有人已经给出了解决方案 比如 https://github.com/springfox/springfox/issues/2265

pandas.DataFrame中pivot()如何实现行转列的问题(代码)

My teenage son Karl became withdrawn after his father died.?

小题1:C 小题2:A 小题3:D 小题4:B ,4, My teenage son Karl became withdrawn after his father died. As a single parent, I tried to do my best to talk to him, but the more I tried, the more he pulled away. When his report card arrived during his junior year, it said that he had been absent 95 times from classes and had six failing grades for the year. At this rate he would never graduate. I sent him to the school adviser, and I even begged him. Nothing worked. One night I felt so powerless that I got down on my knees and pleaded for help. “Please God, I can"t do anything more for my son. I"m at the end of my rope. I"m giving the whole thing up to you.” I was at work when I got a phone call. A man introduced himself as the headmaster. “I want to talk to you about Karl"s absences.” Before he could say another word, I choked up and all my disappointment and sadness over Karl came pouring out into the ears of this stranger. “I love my son but I just don"t know what to do. I"ve tried everything to get Karl to go back to school and nothing has worked. It"s out of my hands.” For a moment there was silence on the other end of the line. The headmaster seriously said, “Thank you for your time,” and hung up. Karl"s next report card showed a marked improvement in his grades. Finally, he even made the honor roll. In his fourth year, I attended a parent-teacher meeting with Karl. I noticed that his teachers were astonished at the way he had turned himself around. On our way home, he said, “Mum, remember that call from the headmaster last year?” I nodded. “That was me. I thought I"d play a joke but when I heard what you said, it really hit me how much I was hurting you. That"s when I knew I had to make you proud.” 59. By saying “Karl became withdrawn”, the author means that the boy changed entirely and_____. A. preferred to stay alone at home B. lost interest in his studies C. refused to talk to others D. began to dislike his mother 60. There was silence on the other end of the line because. A. the speaker was too moved to say anything to the mother B. the speaker waited for the mother to finish speaking C. the speaker didn"t want the mother to recognize his voice D. the speaker was unable to interrupt the mother 61. The sentence “... he even made the honor roll” means that . A. he was even on the list to be praised at the parent-teacher meeting B. he was even on the list of students who made progress in grades C. he was even on the list of students who had turned themselves around D. he was even on the list of the best students at school 62. What is the main idea of this passage? A. Children in single-parent families often have mental problems. B. Mother"s love plays an important role in teenagers" life. C. Being understood by parents is very important to teenagers. D. School education doesn"t work without full support from parents.

line camera怎么画线

line camera怎么画线 LINE camera基本功能 有些人刚开始使用会找不到「美容模式」介面怎么切换,只要执行右下角的切换键即可(我个人觉得这个模式比较直觉好用),虽然可能很多人都比我会用「LINE camera」,但在此还是简单的由基本功能开始介绍,执行「照相机」开始拍照(「相簿」则是由现成的照片挑选进行加工): 照相机操控介面如下,一般来说只会用到镜头切换,在这个介面下选择贴图与特效的效果都是即视即得的,你也可以先设定好配置再拍照会更加生动: 拍照后可以执行「详细」来调整亮度与对比,画面下方可以选择滤镜、相框、贴图、涂鸦、文字等美工效果 「FX」是滤镜功能,种类非常多,您可以左右滑动切换不同效果,也可以手动调整滤镜的深浅效果: 「相框」则是可以让作品加入更多有去元素,后半段的卡通相框更是强力推荐: 「贴图」则是LINE camera的拿手好戏,您可以由内建的贴图小铺购买下载各式贴图,样式一般来说都与LINE不太相同,为了相机功能另外绘制的比较多: 除了有付费贴图以外也有各种免费图样与基本的免费贴图样式 选择后就可以放在您的作品上了: 「涂鸦」可以选择笔刷与颜色在照片上画画,「文字」则是可以加入想要加入的文字: LINE camera美容相机功能介绍 「美容」功能则是最近加入的,很多朋友都不知道它的妙用无穷,我个人使用觉得不会输给「美图秀秀」或「美人相机」,可选择直接拍照或是由相簿中挑选照片修改: 拍照或选好照片后请执行「选择」–>「美容」: 执行后系统会自动帮您做调整亮度与面板的光滑度,如果觉得「磨皮」磨的不够的话还可以自行调整(太夸张的话会没有毛细孔XD): 「脸型」功能可以帮你改成瓜子脸,看你想瘦脸受到什么程度都可以: 「眼睛」可以调整瞳孔大小(改到快变成外星人了XD): 「点选修饰」则是可以手动调整要修饰的「点」,功能有瘦脸、大眼效果、丰满度与缩鼻等: 在这边的「瘦脸」功能就是由使用者自己决定要瘦哪个角落与方向性,甚至可以往外推,灵活度更大: 大眼效果也是一样的,自己决定要放大瞳孔就好: 觉得鼻翼太大可以自己再上面点一下鼻子就变小了,不满意还可以回上一步重来: 「丰满度」则可能是部分女性会想要的功能,以前都要透过PS大神,现在自己来就可以,只要对着想要增大的范围点一下就会变大一些,点越多下就越大: 嗯…调一下可以,调太多就滑稽了,而且景物还会被「力场」干扰变形: 改过头就会像这样XD(图片来源): 最后的「美肤」可以帮您去除痘痘与黑眼圈,「调整色调」可以修正色温 VB line画线问题 Form1.DrawWidth = 10 改数字就可以了,这句放在line,或pset前就可以了 line函式画线怎么改变线条的颜色 你是用的什么语言哪?它们各不相同。例如: BASIC、VB:lin2(x1,x1,颜色代号) VFP :控制元件.backcolor=getcolor() 或 控制元件.backcolor=rgb(红色代号,绿色代号,蓝色代号) C、C++:setcolor(颜色代号) I got my camera (on my tenth birthday ) 对画线部分提问 ___ ___ ___ get your camera? ②when did you vb 用line 画线的问题 把Step去掉,Step是步长,所以会发生座标变更 line camera怎么购买 以下是LINE相机贴图购买步骤: 1、进入LINE相机,点选左下角的“商店”。 2、选择你喜欢的贴图,点选。 3、点选“购买”按钮购买。 若贴图无法购买,可能是以下情况:    1、贴图为限期销售 超过销售期限将无法购买。 2、贴图尚未发售 Apple Store及Google Play的贴图发售日期可能不同。 3、不支援结算功能 部分国家及地区不支援Google Play的付费系统。 上述情况下,贴图商店的商品将无法显示或供您购买。 怎么在VB6.0中实现LINE多线控制元件自动画线. 是不是动态新增来画? private sub mand1_click dim l as vb.line static i& set l=controls.add("vb.line","l" & i) i=i+1 with l .x1=i*.150 .y1=i*120 .x2=.x1+1500 .y2=.y1+1200 .visible=true end with end sub DXP 中可以用画线工具(place line)画导线吗 不行,虽然pcb可以做出来,但是你画线的时候没有网路,会报错显示绿色!如果你的pcb没有网路你可以这样画,有网路你就点选P-T!还不理解继续沟通! Protel 99 SE画封装时,怎么用Line画线,而不是PolyLine-PCB专区 PCB封装里画元件外框丝印的话,直接用画线工具在丝印层画就可以了。 我用javascript画线,怎么画线呢??? < xmlns:v="urn:schemas-microsoft-:vml"> <HEAD> <META -equiv="Content-Type" content="text/;Charset=gb2312"> <title>vml例项</title> <STYLE> v:*{behavior:url(#default#VML);}/*宣告V为VML变数*/ </STYLE> <SCRIPT LANGUAGE="JavaScript"> var x,y,a,b; function drawline(fromX,fromY,toX,toY){ var strElement= "<v:Line id="line_"+fromX+"_"+fromY+"_"+toX+"_"+toY+"" from="" + fromX + "," + fromY + "" to="" + toX + "," + toY + "" strokecolor="red"></v:Line>"; var newPoint = document.createElement(strElement); document.getElementById("map").appendChild(newPoint); } function draw(){ if(x==undefined&&b==undefined){x=window.event.x;y=window.event.y;return false;} a=window.event.x;b=window.event.y; drawline(x,y,a,b) x=a;y=b; } function draws(){ if(x==undefined&&b==undefined){return false;} if(x==window.event.x&&b==window.event.y){return false;} if(document.getElementById("TempLine")){document.getElementById("TempLine").outerHTML=""} var strElement= "<v:Line id="TempLine" from="" + x + "," + y + "" to="" + window.event.x + "," + window.event.y + "" strokecolor="red"></v:Line>"; var newPoint = document.createElement(strElement); document.getElementById("map").appendChild(newPoint); } </SCRIPT> </HEAD> <BODY> <table border=1 align=center> <tr> <td><div id="map" class="page_speeder_168859296" onmousedown="draw();" onmousemove="draws()"></div></td> </tr> </table> </body> </> 以上程式码仅支援IE浏览器。

雅各书英文名怎么是James?而不是Jacob?

两个都是同样中文译名. Jacob 译雅各是在旧约 ; James 也译雅各是在新约, 是耶稣的大弟弟.只是英文名两个用不同名, 比较易分明, 但中文可能有时混乱.

Born out of a need for industry self-regulation, ABS published its first technical standards, Rules for Survey and Classing Wooden Vessels, in 1870. When the era of wooden ships gave way to iron, ABS established standards for these structures, published as Rules for Survey and Classing of Iron Vessels. Similarly, when iron gave way to steel, ABS Rules for Building and Classing Steel Vessels were established and published in 1890. These Steel Vessel Rules continue to be revised and published annually.ABS的首次在纽约州特许在1862年,以证明船长。它已涉及安全标准的发展和改善。出生需要行业自律,ABS公布了其第一个技术标准,为调查和分级木船,在1870年的规则。当木船时代让路铁,ABS的铁容器的调查和分档规则公布这些结构,建立标准。同样,当铁让路钢,建设和分级铁壳船ABS的规则,建立,并在1890年出版。这些钢船规则继续每年进行修订并公布。它的优势也就在于它的服务项目Services[edit] ClassificationThe responsibility of the classification society is to verify that merchant ships and marine structures presented to it comply with Rules that the society has established for design, construction and periodic survey. Classification itself does not judge the economic viability of a vessel. Neither is the society in a position to judge whether a vessel is ultimately employed according to the stated intended purpose for which it was classed. The classification society records, reports and recommends in accordance with what it has seen at the time of a vessel"s construction and subsequent surveys. If a vessel is found not to comply with the Rules, and the recommendations of ABS are not followed, then the society will suspend or cancel classification.Rules are derived from principles of naval architecture, marine engineering and associated disciplines. A new Rule, or a proposed change to an existing Rule, originates with one of the ABS technical committees, from in-service experience, from a new IACS Unified Requirement or from the ongoing research conducted by the technology staff at ABS. Research projects are conducted either directly by ABS or are undertaken jointly with industry, with academic and governmental organizations or with other appropriate partners to best draw on the most qualified sources available.When an owner first requests that a vessel or structure be classed, the shipyard or design agent presents drawings and calculations to ABS for a systematic detailed review for compliance with the Rules. ABS engineers review the plans to verify that the structural and mechanical details conform to the Rule requirements.After a design has been approved by ABS engineers, ABS field surveyors attend the vessel at the shipyard from keel laying to delivery.The surveyors verify that the approved plans are followed and the Rules are adhered to. During the construction of a vessel built to ABS class, surveyors witness, at the place of manufacture or fabrication, the tests of materials for the hull and certain items of machinery as required by the Rules. They also survey the building, installation and testing of the structural and principal mechanical and electrical systems.When completed, a vessel undergoes sea trials attended by an ABS field surveyor. The vessel is then presented to the ABS Classification Committee which assesses the vessel"s compliance with the Rules based on the collective experience of the Committee members and recommendations from the ABS staff. The Classification Committee is composed of ABS Members drawn from the maritime industry, United States Coast Guard and ABS officers. When accepted by the Committee, formal certification is issued to the vessel. The vessel"s classification information, characteristics and other particulars are then entered into the ABS Record – the electronic register of vessels classed by ABS maintained and updated on the ABS web site.ABS Rules require that every classed vessel be subject to periodic surveys to determine whether it is maintained in accordance with classification standards. Surveys are based on a five-year cycle of Annual Surveys, an Intermediate Survey to be completed between the second and third years of the five-year period, and a comprehensive Special Survey including dry docking at each fifth anniversary from the time of the vessel"s delivery.Plimsoll line of ABS[edit] CertificationABS also offers certification to specified standards. Whereas classification requires periodic surveys of the classed vessel or offshore unit throughout its life, certification verifies that the item conforms to designated standards at a specified time. Certification can establish compliance with ABS, national, international, industry or other standards.[edit] Offshore & Energy ServicesABS also develops standards for the design, construction and operational maintenance of offshore drilling and production units and for gas carriers of all types. These standards cover mobile offshore drilling units (such as jackup rigs, semisubmersible rigs, and drill ships), floating offshore production installations (spars, tension leg platforms, semisubmersibles and FPSOs/FSOs), fixed offshore installations, pipelines, risers, and single point moorings.[edit] Statutory ServicesABS also acts as a Recognized Organization on behalf of more than 100 governments. A Recognized Organization is authorized by a flag State to conduct plan review and statutory surveys on ships registered under that flag on behalf of the nation"s maritime administration. Typical regulations include the U.S. Code of Federal Regulations (CFR), SOLAS, MARPOL regulations, and the Load Line Convention. In addition to the national or international tonnage certificates, Panama and Suez Canal tonnage certificates can be issued by ABS on behalf of those authorities.[edit] Naval Vessel StandardsThe ABS Rules for Building and Classing Naval Vessels are developed for naval vessels. The standards address the bulk of hull, mechanical, electrical, environmental and safety related criteria for the vessels.The Naval Vessel Rules have restricted distribution, unlike the other ABS Rules and Guides which are available for download or hardcopy purchase.[edit] Rapid Response Damage Assessment (RRDA) ProgramDecisions made within the first few hours following a maritime casualty can determine the outcome, i.e. whether or not the vessel will remain intact and the potential environmental impact. The RRDA program provides an organized team of engineers and naval architects during emergency situations.Since 1993, RRDA engineers have contracted HECSALV software to model more than 2,000 vessels including floating production, storage and offloading (FPSO) units, tankers, bulk carriers, gas carriers, semisubmersibles and spars classed by the major classification societies. Teams have responded to more than 180 worldwide incidents ranging from tank explosions, groundings, collisions and fires to minor structural damage, flooding, trimming to replace stern seals, emergency drydockings and structural evaluation with missing structure in repair situations.The principal role of the RRDA team is to assist the Master and owner"s technical personnel. With the ability to quickly calculate the effect of damage to hull structure and free-flooding of internal spaces, we help the owner/operator minimize further stressing of the hull, loss of the vessel due to inadequate stability or spilling harmful fuel and cargo into the environment. The RRDA team can also interface with the vessel"s class society and flag or port State officials to provide technical documentation to support proposed temporary repairs, operations, single voyage requests or other related requirements.服务ClassificationThe船级社的责任,以验证商船和海洋结构向它提出的符合社会既定规则的设计,施工和定期调查。分类本身并不判断船只的经济活力。既不是社会中的位置来判断是否最终聘用,按照既定的预期目的,它被归类船只。船级社记录,报告和建议按照什么,它已经在一艘船的建设和后续调查时看到的。如果船只被发现不遵守规则,不遵守ABS的建议,那么社会将暂停或取消分类。来自造船,海洋工程及相关学科的原则规则。一个新规则,或建议改变现有规则,起源与服务经验,ABS技术委员会之一,从一个新的国际船级社协会统一要求,从正在进行的研究,在ABS的技术人员进行。研究项目直接进行ABS或与产业界共同承担,学术和政府机构或其他合适的合作伙伴,最好画上最合格的来源获得。当雇主首先要求的船只或结构被归类,船厂或设计代理系统化遵守规则的详细审查图纸和计算的ABS。 ABS的工程师审查核实,符合规则要求的结构和机械的细节计划。ABS实地调查设计已通过ABS工程师批准后,参加在从龙骨,敷设delivery.The验船师验证,批准的计划遵循的规则是坚持的造船厂的船只。在建ABS类,验船师见证,在生产或制造地方的船只建设,船体材料和机械的某些项目的测试要求的规则。他们还调查的结构和主要的机械和电气系统的建设,安装和测试。完成时,一艘船经过试航ABS场验船师参加。的船只,然后提交给评估船只遵守规则的基础上,委员会成员和来自ABS的工作人员的建议集体经验的ABS分类委员会。分类委员会由来自航运业,美国海岸警卫队和ABS人员的ABS的成员。当委员会所接受,正式认证的船只发出。船只的分类信息,特点及其他详情,然后进入ABS的记录 - 电子寄存器级船只通过ABS ABS网站维护和更新。ABS的规则规定,每类船只须定期调查,以确定它是否是按照分类标准保持。调查是根据按年统计调查的五年周期,1中级调查五年期的第二和第三年之间完成,1全面的特别调查,包括在每十五周年从船的时间干坞交货。ABS [编辑普利姆索尔]行CertificationABS也提供认证规定的标准。而分类级的船只或境外单位在其整个生命周期调查,认证验证,该项目符合在指定的时间指定的标准。认证可以建立符合ABS,国家,国际,行业或其他标准。[编辑]海洋能源ServicesABS还开发海上钻井和生产经营单位的设计,施工和运营维护标准和所有类型的气体运输船。这些标准涵盖了移动式近海钻井装置(如自升式钻井平台,半潜式钻井平台,钻井船),海上浮动生产装置(梁,张力腿平台,的semisubmersibles的FPSO / FSOs),固定式近海装置,管道,立管,单点系泊。 法定ServicesABS还充当上100多个国家的政府代表的认可组织。船旗国认可组织授权,代表国家海事管理机构根据该标志注册的船舶上进行计划,审查和法定检验。典型的法规,包括美国联邦法规法典(CFR),国际海上人命安全公约“,”防污公约“的规定,船舶载重线公约”。除了国家或国际吨位证书,巴拿马和苏伊士运河吨位证书可以由ABS发出这些机构的代表。 海军舰艇StandardsThe ABS建设和分级舰艇规则制定的海军舰艇。标准解决大部分船体,船只的机械,电气,环境和安全相关的标准。海军舰艇规则限制分布,不像其他的ABS可下载或购买印刷版的规则和指南。最初的几个小时内作出快速反应的损害评估(RRDA)ProgramDecisions后,海事伤亡事故的,可以决定胜负,即不论该船只将保持不变,对环境的潜在影响。 RRDA计划在紧急情况下提供了一个有组织的团队工程师和海军建筑师。自1993年以来,RRDA工程师承包HECSALV软件模拟2000余艘,其中包括浮式生产储油和卸油(FPSO)为单位,油轮,散装船,液化气船,semisubmersibles和主要船级社级的梁。队已经回答了180多个全球范围从油箱爆炸,搁浅,碰撞和火灾轻微的结构性破坏事件,洪水,修剪,以取代失踪结构修理情况船尾密封,紧急drydockings和结构评价。的RRDA队的主要作用是协助主及业主的技术人员。我们有能力快速计算损害船体结构和内部空间的自由泛滥的影响,帮助进一步强调的船体,船只不够稳定造成的损失或蔓延到有害的燃料和货物的所有者/经营者减少环境。 RRDA的团队还可以与接口类船只的社会和标志或港口国官员提供的技术文件,以支持所提出的临时修理,操作,单航次的请求或其他相关的要求。

WPF中,当Viewport2DVisual3D.Camera使用动画时为什么是冻结的

当你动画化Viewport2DVisual3D对象的“照像机”属性时,你会得到一个“错误操作异常”:冻结的对象不能被冻结“。  Freezable对象在有些情况下比如设置在样式中时会被冻结,有关Freezable对象,请参照以下MSDN的相关文档:  http://msdn.microsoft.com/en-us/library/ms750509.aspx  这里的原因就是WPF不会冻结Viewport2DVisual3D对象,WPF所做的就是制作一个“camera “冻结的副本并把它分配给对应的转换(underlying transformation),这些转换会在点击测试机制中取消Viewport2DVisual3D对象的点击性能,从而使其不能与用户交互。

gstreamer分析-rtp流的接收

u2003关于数据流的接收过程,[1]有很好的分析。这个问题,令人困惑,依然有些东西没有搞明白。gst_pad_start_task()创建任务,使得gst_base_src_loop()被循环调用。 u2003udosrc怎么同rtpbin关联起来呢?gst-lpugins-good/tests/examples/client-rtpaux.c下有个例子,有个图: u2003udosrc和rtpbin都继承了element。gst_element_link_pads将两者连起来。 u2003rtpbin中的pad是如何接收数据呢? gst_pad_push中调用的chainfun就是这个gst_rtp_session_chain_recv_rtp。 u2003接下来分析rtp数据流的处理,以on-feedback-rtcp这个类型的消息为例。 u2003前前后后一共浪费了六天时间,好奇心害死猫。以后应该研究一些数学密集型的程序,而不是逻辑密集型的程序。 u2003剧终。 [1] GStreamer插件架构简析

athome video streamer怎么用

  进入软件后,你可以看到一个实时影像,点击左上角进入菜单界面,选择第一项更改密码,输入自定义用户名和密码并确认保存。然后,记下设备的CID代码(屏幕右上角),再将手机放置到一个合适的位置上。  如何放置手机也有一定技巧,你可以使用一些物体支撑它,或者选择专用的支架。放置位置你可以选择书架等稍微隐蔽一点的位置,并进行一定的伪装;最好还要拥有电源插座,可以保证手机的不间断供电。  安放好手机之后,就可以通过另一部Android或iOS设备来查看监控画面了,一台设备最多可以添加5个摄像头,十分方便。不过,该应用仅限于android或iOS系统,并不能支持Aindows及Mac桌面系统。首先,你要在软件商店中下载“AtHome Camera”应用,然后进入软件点击左上角的添加按钮,输入CID代码、用户名和密码,点击保存后就可以连接远程账户了。  此时,点击相关的摄像头,就能进入到监控画面,可以进行拍照、前后摄像头切换和闪光灯开关操作。不过,目前的版本还不支持视频录制功能,还是希望软件商可以尽快添加。

怎样编译和配置GStreamer?

GStreamer无疑是一个美观的设计,但初学者往往觉得结构复杂,难以掌握。编译起来也很麻烦:) 本文列出了编译和配置GStreamer的主要步骤,给需要的人提供一个参考。 像其它的Linux开源项目一样,GStreamer也是采用包括autoconf,automake在内的GNU build system来编译的。而且,GStreamer在编译和安装时还要依赖于其它的库,这些库至少包括:pkg-configGLiblibxml2 liboil 这些库都使用pkg-config来提供include路径和library路径等编译信息,而不是像很多开源项目一样在执行configure脚本的时候用CPPFLAGS/CFLAGS环境变量来指定。 这些库很容易通过google找到,一般以“*.tar.gz”或“*.tar.bz2”压缩文件的形式存在。使用tar命令解压:tar xzf *.tar.gz或tar xjf *.tar.bz2 解压后一般会生成一个源文件目录,先面的命令都要进入到各个库的源文件目录内执行。 具体编译和安装步骤如下: (1)确定各个库的安装路径。为描述方便,假设如下的安装路径:pkg-config: /usr/local/install-pkg-config/Glib: /usr/local/install-glib/libxml2: /usr/local/install-libxml2/liboil: /usr/local/install-liboil/GStreamer Core: /usr/local/install-gstcore/GStreamer Base Plugins: /usr/local/install-plugins-base/ (2)设置环境变量。下面的命令按bshell/bash的语法,cshell中应该用setenv。 export PATH=/usr/local/install-pkg-config/bin:$PATH export PKG_CONFIG_PATH="/usr/local/install-glib/lib/pkgconfig:/usr/local/install-libxml2/lib/pkgconfig:/usr/local/install-liboil/lib/pkgconfig:/usr/local/install-gstcore/lib/pkgconfig:/usr/local/install-plugins-base/lib/pkgconfig" 第一个命令是将pkg-config这个工具加入到PATH变量中,这样在执行configure脚本时就能够调到刚刚安装好的pkg-config。 第二个命令是设置pkg-config的搜索路径,在执行configure脚本时会调用pkg-config得到所依赖的头文件和库。 (3)编译和安装pkg-config。 ./configure --prefix=/usr/local/install-pkg-configmakemake install 执行configure脚本时用--prefix指定安装路径 (4)编译和安装GLib。 ./configure --prefix=/usr/local/install-glibmakerm -rf /usr/local/install-glib/include/glib.h /usr/local/install-glib/include/gmodule.h make install (5)编译和安装libxml2。 ./configure --prefix=/usr/local/install-libxml2makemake install (6)编译和安装liboil。 ./configure --prefix/usr/local/install-liboilmakemake install (7)编译和安装GStreamer Core。 ./configure --prefix=/usr/local/install-gstcoremakemake check (optional) make install (8)编译和安装GStreamer Base Plugins。 ./configure --prefix=/usr/local/install-plugins-basemakemake check (optional) make install (9)编译和安装GStreamer的其它plugins,包括gst-plugins-good,gst-plugins-bad等。可选。与编译安装gst-plugins-base类似。 (10)设置运行环境。要运行GStreamer,需要设置GST_PLUGIN_PATH环境变量,指明GStreamer Core和Plugins的库路径。 export GST_PLUGIN_PATH="=/usr/local/gst/install-gstcore/lib:=/usr/local/install-plugins-base/lib" 如果还安装了其它plugins,也要加到GST_PLUGIN_PATH路径里。 另外,如果已有的tool chain版本不够,还需要更新tool chain。常需要做的是安装新版本的autoconf和automake。
