[Greenplum数据库分页查询性能优化]的搜索结果

...以更好地实现工厂级的数据采集和管理； 不再基于DCOM通讯，不需要进行DCOM安全设置； OPC UA定义了统一数据和服务模型，使数据组织更为灵活，可以实现报警与事件、数据存取、历史数据存取、控制命令、复杂数据的交互通信； OPC UA比OPC DA更安全。OPC UA传递的数据是可以加密的，并对通信连接和数据本身都可以实现安全控制。新的安全模型保证了数据从原始设备到MES,ERP系统,从本地到远程的各级自动化和信息化系统的可靠传递； OPC UA可以穿越防火墙，实现Internet 通讯。 依赖 我们通常不会从头写，可以基于OpcUa.core.dll库和OpcUa.Client.dll库，而且附上这2个库的源代码。 配置OpcUA Server 您可以安装任何一款支持OPCUA的服务端软件进行以下配置（此为示例配置，您可根据你的实际情况进行配置） 1、OpcUa Server Url：opc.tcp://192.168.100.1:4840。 2、OpcUa EndPoint：[UaServer@cMT-EAB9] [None] [None] [opc.tcp://192.168.100.1:4840/G01] 3、PLC Device Name：Siemens S7-1200/S7-1500 4、Account：user1 5、Password：自己设置 6、在PLC中开了2个数据块，分别为DB4长度110个字、DB5长度122个字。 7、对应第4块创建标签，第一个名称为DB4.0-99，地址为DB4DBW0.100，数据类型为Short，长度100，即定义长度最长为100的Short数组。第二个名称为DB4.100-109，地址为DB4DBW100.10，数据类型为Short，方便快速读取。 5、对应第5块创建3个标签，第一个名称为DB5.0-99，地址为DB5DBW0.100，数据类型为Short，第二个名称为DB5.100-121， 地址为DB5DBW100.22，数据类型为Short，即定义长度最长为100的Short数组。方便快速读取。第三个标签名称为DB5DBW64，地址为DB5DBW64，数据类型为Short。 具体如下图： 关键代码 using System;using System.Collections.Generic;using System.Linq;using Opc.Ua.Helper;using Mesnac.Equips;namespace Mesnac.Equip.OPC.OpcUa.OPCUA{public class Equip : BaseEquip{region 字段定义private bool _isOpen = false;

...部变量，即心流的一些数据，我们可以大致的判断出，程序在干些什么。对于这样的解释你可能难以接受，接下来的两个例子或许会让你接受这一事实。 现在科学家只要扫描人脑，就能在测试者自己有所感知之前，预测他们会有什么欲望，会做出怎样的决定。例如，在一次实验中，受试者躺在一台巨大的脑部设备里，两手各自拿着一个开关，受试者可以随机的选择在何时按下那个开关。而科学家通过观察受试者的大脑神经活动，就能在受试者做决定之前知道受试者做了怎样的决定。也就是说，当这些内部输出被外部观测者“灵魂”所察觉的时候，心流自身已经做出了决定。7 或许你没有亲自做过这个实验，并不相信实验的结论，但是还有一个实验，你现在就可以给自己做一个测试。相信对于大家心算100以内的乘法没有什么问题，那么请各位充分运用自己的自由意志，即本文中的“灵魂”去控制你的大脑心算5672，注意在计算的过程中不要让自己的大脑去思考其他的任何事情，用尽快的速度计算出结果。当然，你会发现你根本做不到，无论如何你都无法控制那先奇奇怪怪的想法出现在你的大脑里，至于大脑为什么会像你控制的那样去计算5672，接下来我会给出人类的大脑思维模型。 生物的模型 生物的模型分为两部分，一部分我称为确定机，一部分我称为概率机。 确定机 确定机是指只要输入确定，那么就会产生确定输出的部分，而对于输入的概率性则不予考虑。例如，当生物多次看到同一个画面的时候会在大脑里形成同样的图像，因为每次输入的光信号都是一样的，在生物内部进行的信号传递过程也是一样的，所以在大脑里形成的图像输出也是一样的。现在人类所生产的绝大多数工具就是一个确定机的模型，如果相同的输入，不管输入多少次都会得到相同的输出。确定机也是生物模型的基础部分，构成生物的绝大部分，实际上，除了大脑，生物的任何部分都是一个确定机的模型，而大脑也有一部分的确定机模型。对于确定机，所有的内部过程和输出都不会被“灵魂”检阅，当然生物上可以通过解剖或其他更先进的方式去检查生物内部确定机的工作状态。 概率机 概率机是指即使输入确定，输出的确定性也指限制在一定的概率范围之内，会以不同但是给定的概率输出多个输出。当然给定的概率可以是确定机给出的确定概率（只在输入确定的情况下才确定），也可以是概率机给出的概率概率。概率机构成生物的大脑部分，当然一部分低等生物只由确定机构成。对于概率机，有一部分输出会被“灵魂”检阅，而“灵魂”是否检阅取决于“灵魂”本身，当然，对于概率机的工作状态，也可以通过解剖或其他更先进的方式去检查。 生物思考的过程 对于不同的生物，大脑可以同时进行的事情是有限的。就像现在的电脑手机一样，有严格的内存限制，对于大脑来说，同时启用着多个线程，每个线程所占用的内存不同，但是所有线程所占用的内存总和不得超限。对于每个线程，会随机的考虑一些事件，这些事件包括记忆中的事件，和当时正在发生的事件，对于每个事件出现在线程中的概率不同。 不同事件的概率遵循的规律大致有以下几条： 1.对记忆中的事件，事件越久远概率越低。 2.对当时正在发生的事件，概率大致相同。 3.与当时线程中事件有关的事件概率高，无关的概率低。 4.与线程中的事件相关的个数越多，概率越高 5.对不同的心流状态，概率分配有所不同。 6.每个个体对不同的事件有不同的概率分配方案。 7.待补充。 可以说，大脑中的一切过程都是随机的。那这样的话，生物的思考过程究竟如何进行呢？其实很简单，单个概率可能代表随机，但是多个概率就有可能表示必然。我还是举那个5672的例子，为什么你会真的去心算这个结果，大致的过程是这样的，如果大脑的思考频率以毫秒计的话，假设看5672用了200毫秒，其中每毫秒除了这一事件，还有其他的99个事件，那么刚看完就开始计算的概率为1-0.99200=0.8660203251,看完后1秒之内还没有开始计算的概率为0.991000= 4.31712474107 e-5，可以说即使大脑中随机的杂念再多，思考的过程也会如约开始。假设线程中与事件相关的事件出现的概率为0.3，同理，在开始计算后1秒内大部分时间都在思考与计算有关的内容，当然也有可能会走神，即出现大范围的无关事件，但是这只会影响最后计算出结果的时间先后，并不会影响整个过程的进行。这也就是说，大脑的思考过程，其实就是由多个概率所确定的必然事件。 灵魂的旁观者 综上所述，作为个体唯一存在的“灵魂”处在一个旁观者的位置，而所谓的自由意识，主观意识不过是概率机的产物。那么这样就产生了两个问题。 第一个问题，你不觉得“灵魂”所在的肉体更像是一个囚笼吗？“灵魂”可以偶尔窥探外界，但无法做任何事情，只能默默得看着一切发生。尴尬的以为是自己做的，实际上就像看电影，每次看电影的时候，我都会以为我处在电影里面的世界。而现实就是，因为“灵魂”只能看肉体主演的这部“电影”，所以看的入迷了。其实，人类从解放双手，开发智力，使用工具，到探索宇宙，最大的进步莫过于发现自己其实仍处于囚笼之中。要怪就怪这囚笼建造地太过美好。而创建这一囚笼的“上帝”，把我们关在肉体这个囚笼里面，并且把我们的感知限制在有限的范围内，有限的嗅觉，16至20000赫兹的听觉，400纳米到700纳米的视觉，在感知中隔绝了我们对我们的唯一存在——“灵魂”的感知。 第二个问题，对于自己本身来说，表征自己存在的“灵魂”自己是可以确定的，而对于其他人，因为限制了对“灵魂”的感知，所以无法确认别人，别的生物体内这一旁观者的存在。也可以这么理解，你知道自己被关在一间囚笼里面，而不知道隔壁囚笼是否也关了一个存在。那么世界这个大监狱里面，可能只有一小部分，甚至只有你一个孤独的存在。而究竟为何我们或我被困于此，我不得而知，可能就像我们做研究的时候的小白鼠一样，“上帝”也在观察着我们或我的一举一动，这也是我这篇文章取这个题目的原因。小白鼠的逆袭，一开始我只是平凡的活着，说实在的其实做一个平凡人安安稳稳的一生还是很不错的，但是知道了这个囚笼的存在，就总想着打破它，因为在想到可能只有自己一个存在的时候，会是多么的孤独。就像一个人去看电影，哪怕电影的内容再精彩，再引人入胜，但当电影结束的时候，你才发现，原来我是一个人来的呀。 联系作者 有志向联系读者的：1612860@mail.nankai.edu.cn 未完待续。。。 本篇文章相当于《小白鼠的逆袭》的导读，下一篇我会出逆袭第一步：《思考的最简单模型及其编程实现》，可能用C++，也可能用Java，Python，看作者的心情吧。预计近几个月出吧，快则个把月，多则不知道了，毕竟作者本身还是比较忙的，忙七忙八也不知道在忙什么，嗯，就这样。 小号：在有多个游戏账号的前提下，等级高的号叫作大号，等级较低或者新创建的号叫作小号。 ↩︎ https://baijiahao.baidu.com/s?id=1586028525096880374&wfr=spider&for=pc. ↩︎ http://tieba.baidu.com/p/5127924201. ↩︎ http://tieba.baidu.com/p/5127924201. ↩︎ http://www.lwlm.com/sixiangzhexue/201704/840820.htm. ↩︎ 详细讨论请参见：《未来简史：从智人到智神》第三章：人类的特质。 ↩︎ “Unconscious determinants of free decisions in the human brain” in nature neuroscience, http://www.rifters.com/real/articles/NatureNeuroScience_Soon_et_al.pdf. ↩︎ 本篇文章为转载内容。原文链接：https://blog.csdn.net/qq_39384184/article/details/79288150。 该文由互联网用户投稿提供，文中观点代表作者本人意见，并不代表本站的立场。 作为信息平台，本站仅提供文章转载服务，并不拥有其所有权，也不对文章内容的真实性、准确性和合法性承担责任。 如发现本文存在侵权、违法、违规或事实不符的情况，请及时联系我们，我们将第一时间进行核实并删除相应内容。

由于JavaScript在不同域名下访问会出现由来已久的跨域问题，所以正式部署到服务器使用时，要解决跨域问题。<br/> 对于IE8以上版本浏览器，只需增加一个reponse头：Access-Control-Allow-Origin即可，而对于php、jsp、asp/aspx等动态语言而言，增加一个response头是非常简单的事，例如：<br/> <b>在php：</b><br/><span style="color: red;"> <?php <br/> header("Access-Control-Allow-Origin: ");<br/> ?><br/> </span> <b>在jsp：</b><br/><span style="color: red;"> <% <br/> response.setHeader("Access-Control-Allow-Origin", ""); <br/> %><br/> </span> <b>在asp.net中：</b><br/><span style="color: red;"> Response.AppendHeader("Access-Control-Allow-Origin", ""); </span>，<br/>其他语言里，大家请自行搜索“ajax跨域”。而对于IE8以下的浏览器，大家可以自行搜索“IE6+Ajax+跨域”寻找解决办法吧，也可以联系我们帮助。 </div> </div> </div> <div id="output"></div> </body> <!-- 引入模式2所需的javascript支持库 --> <script

打印：以大文本框中的json数据为数据源，向打印机输出当前所用模板生成的报表； 以后将会有详细的模板设计教程发布，如果您遇到紧急的难题，请向作者咨询。 本篇文章为转载内容。原文链接：https://blog.csdn.net/chensongmol/article/details/76087600。 该文由互联网用户投稿提供，文中观点代表作者本人意见，并不代表本站的立场。

Session与cookie功能效果相同。Session与Cookie的区别在于Session是记录在服务端的，而Cookie是记录在客户端的。 由于cookie 是存在用户端，而且它本身存储的尺寸大小也有限，最关键是用户可以是可见的，并可以随意的修改，很不安全。那如何又要安全，又可以方便的全局读取信息呢？于是，这个时候，一种新的存储会话机制：session 诞生了
