In this paper we present a classifier called bi-density twin support vector machines (BDTWSVMs) for data classification. In the training stage, BDTWSVMs first compute the relative density degrees for all training points using the intra-class graph whose weights are determined by a local scaling heuristic strategy, then optimize a pair of nonparallel hyperplanes through two smaller sized support vector machine (SVM)-typed problems. In the prediction stage, BDTWSVMs assign to the class LABEL depending on the kernel density degree-based distances from each test point to the two hyperplanes. BDTWSVMs not only inherit good properties from twin support vector machines (TWSVMs) but also give good description for data points. The experimental results on toy as well as publicly available datasets indicate that BDTWSVMs compare favorably with classical SVMs and TWSVMs in terms of generalization

There is an unprecedented enthusiasm for radio frequency identification (RFID) technologies today. RFID is based on the exchange of information carried by electromagnetic waves between a LABEL, or tag, and a reader. This technology is currently in full economic expansion, which has manifested itself in widely backed research activities, some of which will be examined in this book.

Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The 34401A may be used to make measurements with the HI and LO inputs connected to mains in such devices, or to the branch outlet itself (up to 300 VAC). However, the 34401A may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltages that may exceed the protection limits of the 34401A. Note: Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, transient overvoltages are also present on circuits that are isolated from mains. The Agilent 34401A are designed to safely withstand occasional transient overvoltages up to 2500 Vpk. Do not use this equipment to measure circuits where transient overvoltages could exceed this level. Additional Notices Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC This product complies with the WEEE Directive (2002/96/EC) marking requirement. The affixed product LABEL (see below) indicates that you must not discard this electrical/electronic product in domestic household waste. Product Category: With reference to the equipment types in the WEEE directive Annex 1, this product is classified as a "Monitoring and Control instrumentation" product. Do not dispose in domestic household waste. To return unwanted products, contact your local Agilent office, or see www.agilent.com/environment/product for more information. Agilent 34138A Test Lead Set The Agilent 34401A is compatible with the Agilent 34138A Test Lead Set described below. Test Lead Ratings Test Leads - 1000V, 15A Fine Tip Probe Attachments - 300V, 3A Mini Grabber Attachment - 300V, 3A SMT Grabber Attachments - 300V, 3A Operation The Fine Tip, Mini Grabber, and SMT Grabber attachments plug onto the probe end of the Test Leads. Maintenance If any portion of the Test Lead Set is worn or damaged, do not use. Replace with a new Agilent 3413

第一步：新建PCB工程文件 并向工程文件里添加PCB文件和原理圖文件 第二步：元件庫、封裝庫設計 部分元器件廠商或者經銷商不提供元件庫和封裝庫，只給了元器件尺寸圖，所以需要自行設計元件 庫文件或是封裝庫文件 元件庫設計： 新建 .SchLib 文件：File -> New -> Library -> Schematic Library 使用Place下拉菜單或使用快捷工具欄放置圖形，引腳等，記得保存！ 封裝庫的設計 新建.PcbLib文件：File -> New -> Library -> PCB Library 使用Place下拉菜單或使用快捷工具欄，畫線，放置孔位，記得保存！第三步：原理圖的繪制 新建.SchDoc文件 ：File -> New -> Schematic 添加元器件庫和封裝庫 在軟件底部菜單欄System中勾選Libraries，打開側面工具欄 在側面工具欄中點擊“Libraries...” -> “Add Library”找到自己保存的庫文件并添加 添加各元器件 可直接從側面工具欄中選擇元器件拖入原理圖中，在拖動過程中按Tab鍵修改元器件信息 添加網絡標識Place -> Net LABEL 快捷鍵（PN） 確定各元器件封裝 打開封裝管理器Tools -> Footprint Manager 快捷鍵（TG） 可挨個修改、檢查各元器件封裝
