  • Data+Processing+in+Smart+Cities

    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.

  • EDGE+for+Mobile+Internet

    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.

  • 半導(dǎo)體仿真工具 silvaco tcad 學(xué)習(xí)資料

    接觸Silvaco TCAD仿真軟件已經(jīng)有很長時(shí)間了,這期間還熟悉了一下ISE TCAD。學(xué)習(xí)的過程中,老師、師兄姐和同學(xué)給了我極大的幫助。這本書的主旨就是希望提供一些對(duì)于Silvaco仿真的可資借鑒的經(jīng)驗(yàn)。學(xué)習(xí)和使用Silvaco的時(shí)候各人的視角會(huì)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?yàn)榱鞒炭刂坪驼Z法都有相通的地方,完全可以參照本書和手冊(cè)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(gè)動(dòng)力是想體驗(yàn)一下IAT在排版書籍上和word的不同。經(jīng)過這次編排覺得各有優(yōu)缺點(diǎn)。IZTX對(duì)排圖片和表格這些浮動(dòng)元素很費(fèi)力。我在排此書的時(shí)候經(jīng)常遇到圖片和表格按照自動(dòng)方式排的位置很差,和文字內(nèi)容脫節(jié)很遠(yuǎn),為此不得不處理圖片,有時(shí)還將表格拆開等。如果各位遇到很脫節(jié)的地方還請(qǐng)見諒。LTX的使用需要有很強(qiáng)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(nèi)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。
