Unit 12 生物识别技术Unit 12-1第一部分：指纹识别在所有的生物技术中，指纹识别是最早期的一种技术。
我们知道，每个人都有自己独特的、不可变更的指纹。
指纹是由手指表皮上的一系列峰谷组成的。
指纹的独特性是由这些峰谷的形状以及指纹的细节点所决定的。
指纹的细节点是指纹局部凸起处的一些特性，这些特性出现在凸起的分叉处或是凸起的截止处。
指纹匹配技术可以被分为两类：基于细节的指纹匹配技术和基于相关性的指纹匹配技术。
基于细节的指纹匹配首先要找出细节点，然后在手指上对应出与它们相关的位置，如图12.1所示。
但是，使用这种方法存在一些困难。
要精确地提取指纹的细节点是很困难的。
而且，这种方法不能很好地考虑指纹峰谷的整体形状。
基于相关性的指纹匹配技术可以解决部分基于细节的指纹匹配方法存在的问题，但它也存在一些自身的缺陷。
基于相关性的匹配技术需要给出已注册过的特征点的精确位置，并且该方法会受图像平移和旋转的影响。
图12.1 基于细节的指纹匹配基于细节的指纹匹配技术在匹配不同大小的细节模型时（未注册过的）会存在一些问题。
指纹上局部的凸起结构不能完全由指纹细节实现特征化。
我们可以尝试另一种表达指纹的方法，它可以获得更多的指纹局部信息并且得到固定长度的指纹编码。
于是，我们只需要计算两个指纹编码之间的欧几里得距离，匹配过程有望变得相对简单。
研发对于指纹图像中噪声更稳健并能实时提供更高精度的算法是重要的。
商用指纹（身份）认证系统对给定的错误接受率要求具有很低的错误拒绝率。
在这点上，任何一项简单的技术都很难实现。
我们可以从不同的匹配技术中汇总多个证据从而提高系统的总体精确度。
在实际应用中，传感器、采集系统、性能随时间的变化是关键因素。
为了评价系统性能，我们有必要对少数使用者在一段时间内进行现场试验。
每天我们可以从法医鉴定、出入口控制、驾驶证登记等多个方面的应用中采集并保存大量的指纹。
基于指纹的自动识别系统需要把输入的指纹与数据库中大量的指纹进行匹配验证。

SA[物料管理之物料状态管理
非限制使用（即合格品状态）、质量检验（待继续检验物料的状态）、预留的、接受预留、未清订单数量（采购订单未入库的数量）、订购寄存（寄售订单未入库的数量）、库存传送（地点）（即工厂间传送的在途库存）、传送（库存地点）（即库存地之间传送的在途库存）、GR 冻结库存（先收货到冻结库位但不做帐）、交货计划（协议计划）、退货（销售订单的退货）、已冻结（质量等原因被冻结的库存）冻结库存即不可用的库存，通常是质检部门做了相关操作，使得这部门货物无法发货或做其他动作！这部分的库存是不被当做现有存货使用的，也就是说，如果销售有2T的需求，而你仓库里刚好有2T，但是冻结的库存，MRP跑出来的数据会提示你现在有2T的需求，要你采购或是生产，并不会将冻结库存的数量计算在内。
在某些情况下库存是不可用的,比如质检不合格或者要预留,就可以将其设置为冻结.需要注意的就是:这些库存不参与可用性分配.SAP物料冻结有什么作用可以禁止此物料做一些操作，例如禁止收仓，禁止物料消耗等等。
盘点时如果库存需要冻结，SAP 提供了2 种方法供选择。
分别是：【1】记账冻结,：如果选择了此按钮，则意味着在盘点凭证里的库存是无法移动的，相当于被冻结。
【2】冻结账面库存,：选择此按钮后，当前的库存会作为记录库存，实际的盘点库存数会跟记录库存对比。
如果需要启用此功能，请在此路径下激活库存地配置：IMG->物料管理->库存管理和实际库存->库存盘点->允许存储位置的登记库存余额冻结(TCode：OMBP)看看这两张图：第一张图表明了记账冻结,产生的效果。
Figure 106: Blocking Goods Movements解释:9 月26 日那天库存为250 EA, 于当天创建盘点凭证，并冻结了库存的收发，盘点过程在9 月28 日完成，输入实际盘点的数量，为255 EA。
到此，冻结解除，库存的收发可以正常进行。
9 月30 日库存的5 EA差异审批通过，过账，在9 月30 日的370 个库存基础上调整。

电子信息工程专业英语教程_第5版 题库
《电子信息工程专业英语教程(第5版)》题库Section A 术语互译 (1)Section B 段落翻译 (5)Section C阅读理解素材 (12)C.1 History of Tablets (12)C.2 A Brief History of satellite communication (13)C.3 Smartphones (14)C.4 Analog, Digital and HDTV (14)C.5 SoC (15)Section A 术语互译Section B 段落翻译Section C阅读理解素材C.1 History of TabletsThe idea of the tablet computer isn't new. Back in 1968, a computer scientist named Alan Kay proposed that with advances in flat-panel display technology, user interfaces, miniaturization of computer components and some experimental work in WiFi technology, you could develop an all-in-one computing device. He developed the idea further, suggesting that such a device would be perfect as an educational tool for schoolchildren. In 1972, he published a paper about the device and called it the Dynabook.The sketches of the Dynabook show a device very similar to the tablet computers we have today, with a couple of exceptions. The Dynabook had both a screen and a keyboard all on the same plane. But Key's vision went even further. He predicted that with the right touch-screen technology, you could do away with the physical keyboard and display a virtual keyboard in any configuration on the screen itself.Key was ahead of his time. It would take nearly four decades before a tablet similar to the one he imagined took the public by storm. But that doesn't mean there were no tablet computers on the market between the Dynabook concept and Apple's famed iPad.One early tablet was the GRiDPad. First produced in 1989, the GRiDPad included a monochromatic capacitance touch screen and a wired stylus. It weighed just under 5 pounds (2.26 kilograms). Compared to today's tablets, the GRiDPad was bulky and heavy, with a short battery life of only three hours. The man behind the GRiDPad was Jeff Hawkins, who later founded Palm.Other pen-based tablet computers followed but none received much support from the public. Apple first entered the tablet battlefield with the Newton, a device that's received equal amounts of love and ridicule over the years. Much of the criticism for the Newton focuses on its handwriting-recognition software.It really wasn't until Steve Jobs revealed the first iPad to an eager crowd that tablet computers became a viable consumer product. Today, companies like Apple, Google, Microsoft and HP are trying to predict consumer needs while designing the next generation of tablet devices.C.2 A Brief History of satellite communicationIn an article in Wireless World in 1945, Arthur C. Clarke proposed the idea of placing satellites in geostationary orbit around Earth such that three equally spaced satellites could provide worldwide coverage. However, it was not until 1957 that the Soviet Union launched the first satellite Sputnik 1, which was followed in early 1958 by the U.S. Army’s Explorer 1. Both Sputnik and Explorer transmitted telemetry information.The first communications satellite, the Signal Communicating Orbit Repeater Experiment (SCORE), was launched in 1958 by the U.S. Air Force. SCORE was a delayed-repeater satellite, which received signals from Earth at 150 MHz and stored them on tape for later retransmission. A further experimental communication satellite, Echo 1, was launched on August 12, 1960 and placed into inclined orbit at about 1500 km above Earth. Echo 1 was an aluminized plastic balloon with a diameter of 30 m and a weight of 75.3 kg. Echo 1 successfully demonstrated the first two-way voice communications by satellite.On October 4, 1960, the U.S. Department of Defense launched Courier into an elliptical orbit between 956 and 1240 km, with a period of 107 min. Although Courier lasted only 17 days, it was used for real-time voice, data, and facsimile transmission. The satellite also had five tape recorders onboard; four were used for delayed repetition of digital information, and the other for delayed repetition of analog messages.Direct-repeated satellite transmission began with the launch of Telstar I on July 10, 1962. Telstar I was an 87-cm, 80-kg sphere placed in low-Earth orbit between 960 and 6140 km, with an orbital period of 158 min. Telstar I was the first satellite to be able to transmit and receive simultaneously and was used for experimental telephone, image, and television transmission. However, on February 21, 1963, Telstar I suffered damage caused by the newly discovered Van Allen belts.Telstar II was made more radiation resistant and was launched on May 7, 1963. Telstar II was a straight repeater with a 6.5-GHz uplink and a 4.1-GHz downlink. The satellite power amplifier used a specially developed 2-W traveling wave tube. Along with its other capabilities, the broadband amplifier was able to relay color TV transmissions. The first successful trans-Atlantic transmission of video was accomplished with Telstar II , which also incorporated radiation measurements and experiments that exposed semiconductor components to space radiation.The first satellites placed in geostationary orbit were the synchronous communication (SYNCOM ) satellites launched by NASA in 1963. SYNCOM I failed on injection into orbit. However, SYNCOM II was successfully launched on July 26, 1964 and provided telephone, teletype, and facsimile transmission. SYNCOM III was launched on August 19, 1964 and transmitted TV pictures from the Tokyo Olympics. The International Telecommunications by Satellite (INTELSAT) consortium was founded in July 1964 with the charter to design, construct, establish, and maintain the operation of a global commercial communications system on a nondiscriminatory basis. The INTELSAT network started with the launch on April 6, 1965, of INTELSAT I, also called Early Bird. On June 28, 1965, INTELSAT I began providing 240 commercial international telephone channels as well as TV transmission between the United States and Europe.In 1979, INMARSAT established a third global system. In 1995, the INMARSAT name was changed to the International Mobile Satellite Organization to reflect the fact that the organization had evolved to become the only provider of global mobile satellite communications at sea, in the air, and on the land.Early telecommunication satellites were mainly used for long-distance continental and intercontinental broadband, narrowband, and TV transmission. With the advent of broadband optical fiber transmission, satellite services shifted focus to TV distribution, and to point-to-multipoint and very small aperture terminal (VSAT) applications. Satellite transmission is currently undergoing further significant growth with the introduction of mobile satellite systems for personal communications and fixed satellite systems for broadband data transmission.C.3 SmartphonesThink of a daily task, any daily task, and it's likely there's a specialized, pocket-sized device designed to help you accomplish it. You can get a separate, tiny and powerful machine to make phone calls, keep your calendar and address book, entertain you, play your music, give directions, take pictures, check your e-mail, and do countless other things. But how many pockets do you have? Handheld devices become as clunky as a room-sized supercomputer when you have to carry four of them around with you every day.A smartphone is one device that can take care of all of your handheld computing and communication needs in a single, small package. It's not so much a distinct class of products as it is a different set of standards for cell phones to live up to.Unlike many traditional cell phones, smartphones allow individual users to install, configure and run applications of their choosing. A smartphone offers the ability to conform the device to your particular way of doing things. Most standard cell-phone software offers only limited choices for re-configuration, forcing you to adapt to the way it's set up. On a standard phone, whether or not you like the built-in calendar application, you are stuck with it except for a few minor tweaks. If that phone were a smartphone, you could install any compatible calendar application you like.Here's a list of some of the things smartphones can do:•Send and receive mobile phone calls•Personal Information Management (PIM) including notes, calendar and to-do list•Communication with laptop or desktop computers•Data synchronization with applications like Microsoft Outlook•E-mail•Instant messaging•Applications such as word processing programs or video games•Play audio and video files in some standard formatsC.4 Analog, Digital and HDTVFor years, watching TV has involved analog signals and cathode ray tube (CRT) sets. The signal is made of continually varying radio waves that the TV translates into a picture and sound. An analog signal can reach a person's TV over the air, through a cable or via satellite. Digital signals, like the ones from DVD players, are converted to analog when played on traditional TVs.This system has worked pretty well for a long time, but it has some limitations:•Conventional CRT sets display around 480 visible lines of pixels. Broadcasters have been sending signals that work well with this resolution for years, and they can't fit enough resolution to fill a huge television into the analog signal.•Analog pictures are interlaced - a CRT's electron gun paints only half the lines for each pass down the screen. On some TVs, interlacing makes the picture flicker.•Converting video to analog format lowers its quality.United States broadcasting is currently changing to digital television (DTV). A digital signal transmits the information for video and sound as ones and zeros instead of as a wave. For over-the-air broadcasting, DTV will generally use the UHF portion of the radio spectrum with a 6 MHz bandwidth, just like analog TV signals do.DTV has several advantages:•The picture, even when displayed on a small TV, is better quality.• A digital signal can support a higher resolution, so the picture will still look good when shown on a larger TV screen.•The video can be progressive rather than interlaced - the screen shows the entire picture for every frame instead of every other line of pixels.•TV stations can broadcast several signals using the same bandwidth. This is called multicasting.•If broadcasters choose to, they can include interactive content or additional information with the DTV signal.•It can support high-definition (HDTV) broadcasts.DTV also has one really big disadvantage: Analog TVs can't decode and display digital signals. When analog broadcasting ends, you'll only be able to watch TV on your trusty old set if you have cable or satellite service transmitting analog signals or if you have a set-top digital converter.C.5 SoCThe semiconductor industry has continued to make impressive improvements in the achievable density of very large-scale integrated (VLSI) circuits. In order to keep pace with the levels of integration available, design engineers have developed new methodologies and techniques to manage the increased complexity inherent in these large chips. One such emerging methodology is system-on-chip (SoC) design, wherein predesigned and pre-verified blocks often called intellectual property (IP) blocks, IP cores, or virtual components are obtained from internal sources, or third parties, and combined on a single chip.These reusable IP cores may include embedded processors, memory blocks, interface blocks, analog blocks, and components that handle application specific processing functions. Corresponding software components are also provided in a reusable form and may include real-time operating systems and kernels, library functions, and device drivers.Large productivity gains can be achieved using this SoC/IP approach. In fact, rather than implementing each of these components separately, the role of the SoC designer is to integrate them onto a chip to implement complex functions in a relatively short amount of time.The integration process involves connecting the IP blocks to the communication network, implementing design-for-test (DFT) techniques and using methodologies to verify and validate the overall system-level design. Even larger productivity gains are possible if the system is architected as a platform in such as way that derivative designs can be generated quickly.In the past, the concept of SoC simply implied higher and higher levels of integration. That is, it was viewed as migrating a multichip system-on-board (SoB) to a single chip containing digital logic, memory, analog/mixed signal, and RF blocks. The primary drivers for this direction were the reduction of power, smaller form factor, and lower overall cost. It is important to recognize that integrating more and more functionality on a chip has always existed as a trend by virtue of Moore’s Law, which predicts that the number of transistors on a chip will double every 18-24 months. The challenge is to increase designer productivity to keep pace with Moore’s Law. Therefore, today’s notion of SoC is defined in terms of overall productivity gains through reusable design and integration of components.。

5. The sampling rate limit the frequency range of the audio file; to reproduce a given frequency, the sampling rate must be at least twice that frequency. For example, if the audio contains audible frequencies as high as 8,000 Hz, your need a sample rate of 16,000 samples per second to reproduce this audio accurately in digital form. This calculation comes from the Nyquist Theorem, and the highest frequency that can be reproduced by a given sample rate is known as the Nyquist Frequency. CDs have a sampling rate of 44,100 samples per second that allows samples up to 22,050 Hz, which is higher than the limit of human hearing, 20,000Hz.

DATA PROCESSING SYSTEM WITH A PLURALITY OF PROCES
专利名称：DATA PROCESSING SYSTEM WITH A PLURALITY OF PROCESSORS, CACHECIRCUITS AND A SHARED MEMORY 发明人：BEKOOIJ, Marco, Jan, Gerrit申请号：IB2008054216申请日：20081014公开号：WO09/050644P1公开日：20090423专利内容由知识产权出版社提供摘要：Data from a shared memory (12) is processed with a plurality of processing units (11). Access to a data object is controlled by execution of acquire and release instructions for the data object, and wherein each processing unit (11) comprises a processor (10) and a cache circuit (14) for caching data from the shared memory (12). Instructions to access the data object in each processor (10) are executed only between completing execution of the acquire instruction for the data object, and execution of the release instruction for the data object in the processor (10). Execution of the acquire instruction is completed only upon detection that none of the processors (10) has previously executed an acquire instruction for the data object without subsequently completing execution of a release instruction for the data object. Completion of the release instruction of each processor (10) is delayed until completion of previous write back, from the cache circuit (14) for the processor to the shared memory (12), of data from all write instructions of the processor (10) that precede the release instruction and address data in the data object. All cache lines of the cache circuit (14) that contain data from the data object is selectively invalidated, each time upon execution of the releaseinstruction and/or the require instruction for the data object.申请人：BEKOOIJ, Marco, Jan, Gerrit地址：NL,NL国籍：NL,NL代理机构：WILLIAMSON, Paul, L.更多信息请下载全文后查看。
数据整理英语
数据整理英语Sure, let's get started.Data organization is a crucial step in any data analysis process. It involves cleaning, structuring, and organizing data to make it easier to analyze and interpret. There are several steps involved in data organization, including data cleaning, data transformation, and data integration.Data cleaning is the process of identifying and correcting errors in the data. This may involve removing duplicate records, correcting misspelled words, or filling in missing values. Data transformation involves converting data into a more suitable format for analysis. This may include converting data from wide to long format, or aggregating data at different levels. Data integration involves combining data from different sources into asingle dataset for analysis.Once the data has been cleaned, transformed, and integrated, it can be organized in a way that makes it easier to analyze. This may involve creating subsets of the data based on certain criteria, creating new variablesbased on existing ones, or aggregating data at different levels.In conclusion, data organization is a crucial step inthe data analysis process. It involves cleaning, transforming, and integrating data to make it easier to analyze and interpret.数据整理是数据分析过程中至关重要的一步。
