Smart Grids provide many benefits for society. Reliability, observability across the energy distribution system and the exchange of information between devices are just some of the features that make Smart Grids so attractive. One of the main products of a Smart Grid is to data. The amount of data available nowadays increases fast and carries several kinds of information. Smart metres allow engineers to perform multiple measurements and analyse such data. For example, information about consumption, power quality and digital protection, among others, can be extracted. However, the main challenge in extracting information from data arises from the data quality. In fact, many sectors of the society can benefit from such data. Hence, this information needs to be properly stored and readily available. In this chapter, we will address the main concepts involving Technology Information, Data Mining, Big Data and clustering for deploying information on Smart Grids.

The General Packet Radio Service (GPRS) allows an end user to send and receive data in packet transfer mode within a public land mobile network (PLMN) without using a permanent connection between the mobile station (MS) and the external network during data transfer. This way, GPRS opti- mizes the use of network and radio resources (RRs) since, unlike circuit- switched mode, no connection between the MS and the external network is established when there is no data flow in progress. Thus, this RR optimiza- tion makes it possible for the operator to offer more attractive fees.

接觸Silvaco TCAD仿真軟件已經有很長時間了,這期間還熟悉了一下ISE TCAD。學習的過程中,老師、師兄姐和同學給了我極大的幫助。這本書的主旨就是希望提供一些對于Silvaco仿真的可資借鑒的經驗。學習和使用Silvaco的時候各人的視角會不一樣,雖然這本書只是介紹一些常用的仿真,例句也有限,但因為流程控制和語法都有相通的地方,完全可以參照本書和手冊的說明靈活地建立仿真以及仿真一些本書未提及的特性。寫本書的另一個動力是想體驗一下IAT在排版書籍上和word的不同。經過這次編排覺得各有優缺點。IZTX對排圖片和表格這些浮動元素很費力。我在排此書的時候經常遇到圖片和表格按照自動方式排的位置很差,和文字內容脫節很遠,為此不得不處理圖片,有時還將表格拆開等。如果各位遇到很脫節的地方還請見諒。LTX的使用需要有很強的耐心和探索精神,也可以說是犧牲精神。不管是MS Office還是ITEX,總的目的是想內容通順,閱讀起來舒服,用什么工具就是“八仙過海,各顯神通”了。

SP協議最早由是由 MMUSIC ETI工作組在1995年研究的,由T組織在1999年提議成為的一個標準。SP主要借鑒了Web網的HTP和SMTP兩個協議3GPPR5/R6的MS子系統采用SP。3GPP制定的MS子系統相關規范推動了SP的發展。lETF提出的P電話信令協議基于文本的應用層控制協議獨立于底層協議,可以使用TCP或UDP傳輸協議用于建立、修改和終止一個或多個參與者的多媒體會話。SIP協議是應用層控制(信令)協議SIP協議支持代理、重定向、登記定位等功能,支持用戶移動。SIP協議和其他協議一起給用戶提供完整的服務,包括:RSP(資源預留協議)RTP(實時傳輸協議)RTSP(實時流協議)SAP(會話通告協議)SDP(會話描述協議)SIP支持以下五方面的能力來建立和終止多媒體通訊用戶定位:確定通信所用的端系統位置用戶能力交換:確定所用的媒體類型和媒體參數用戶可用性判定:確定被叫方是否空閑和是否愿意加入通信呼叫建立:邀請和提示被叫,在主被叫之間傳遞呼叫參數呼叫處理:包括呼叫終結和呼叫轉交Proxy代理服務器》為其它的客戶機代理,進行SP消息的轉接和轉發的功能。消息機制與UAC和UAS相似》對收到的請求消息進行翻譯和處理后,傳遞給其他的服務器》對SP請求及響應進行路由■重定向服務器》接收S|P請求,把請求中的原地址映射為零個或多個地址,返回給客戶機,客戶機根據此地址重新發送請求》重定向服務器不會發起自己的呼叫(不發送請求,通過3x響應進行重定向)》重定向服務器不接收呼叫終止,也不主動終止呼叫
