Information technology, often abbreviated as IT, has become an integral part of modern society. It refers to the use of computers, software, networks, and other devices to store, retrieve, transmit, and manipulate data. In today's digital age, information technology plays a crucial role in various aspects of our lives, including communication, education, business, healthcare, and entertainment.信息技术,通常缩写为IT,已成为现代社会的一个不可或缺的部分。
它指的是使用计算机、软件、网络和其他设备来存储、检索、传输和操纵数据。
在今天的数字时代,信息技术在我们生活的各个方面起着至关重要的作用,包括通信、教育、商业、医疗和娱乐。
One of the most significant impacts of information technology is on communication. With the advent of theinternet, communication has become faster, easier, and more convenient than ever before. Email, instant messaging,social media platforms, and video conferencing have revolutionized the way people interact and exchange information. Distance is no longer a barrier to communication, as individuals from different parts of the world can connect in real-time through various online channels.信息技术最重要的影响之一是在通信方面。
mobile and cellular radio移动和细胞广播in comparison to the relative stability and modest technical developments which are occurring in long haul wideband microwave communication systems there is rapid development and expanding deployment of new mobile personal communication system. These rang from wide coverage area pagers,for simple data message transmission,which employ common standards and hence achieve contiguous coverage over large geographical areas,such as all the major urban centres and transport routes in Europe,Asia or the continental USA.This chapter discusses the special channel characteristics of mobile systems and examines the typical cellular clusters adopted to achieve continuous communication with the mobile user.It then highlights the important properties of current,and emerging,TDMA and code division multiple access(CDMA), mobile digital cellular communication systems.Private mobile radioTerrestrial mobile radio works best at around 250 MHz as lower frequencies than this suffer from noise and interference while higher frequencies experience multipath propagation from buildings,etc,section 15.2.In practice modest frequency bands are allocated between 60MHz and 2GHz. Private mobile radio(PMR) is the system which is used by taxi companies,county councils,health authorities,ambulance services,fire services,the utility industries,etc,for mobile communications.PMR has three spectral at VHF,one just below the 88 to 108 MHz FM broadcast band and one just above this band with another allocation at approximately 170MHz.There are also two allocations at UHF around 450MHz. all these spectral allocations provide a total of just over 1000 radio channels with the channels placed at 12KHz channel spacings or centre frequency offsets. Within the 12khz wide channal the analogue modulation in PMR typically allows 7khz of bandwidth for the signal transmission.when further allowance is made for the frequency drift in the oscillators of these systems a peak deviation of only 2 to 3 khz is available for the speech traffic. Traffic is normally impressed on these systems by amplitude modulation or frequency modulation and again the receiver is of the ubiquitous superheterodyne design,Figure 1.4. A double conversion receiver with two separate local oscillator stages is usually required to achieve the required gain and rejection of adjacent channel signals.One of the problems with PMR receiver is that they are requiredto detect very small signals,typically—120dBm at the antenna output,corresponding to 0.2 uV,and,after demodulating this signal,produce ann output with perhaps 1W of audio equipment, the first IF is normally at10.7MHz and the second IF is very orten at 455KHz . unfortunately,with just over 1000 available channels for the whole of the UK and between 20000and30000issued licences for these systems,it is inevitable that the average busuness user will have to share the allocated channel with other companies in their same geographical area.There are various modes of operation for mobile radio communications networks, the simplest of which is singal frequency simplex. In simplex communication, traffic is broadcast, or one way. PMR uses half duplex(see later Table 15.3) where, at the end of each transmission period, there is a handover of the single channel to the user previously receiving, in order to permit them to reply over the same channel. This is efficient in that it requires only one frequency allocation for the communication link but it has the disadvantage that all units canhear all transmissions provided they are within rage of the mobile and frequencies are allocated for the transmissions. One frequency is used for the forward or downlink, namely base-to-mobile communications. This permits simultaneous two-way communication and greatly reduces the level of interference, but it halves other’s transmissions, which can lead to contention with two mobiles attempting to initiate a call, at the same time, on the uplink in a busy syetem.Although PMR employs relatively simple techniques with analogue speech transmission there have been many enhancements to these systems over the years . Data transmission is now in widespread use in PMR systems using FSK modulation. Data transmission also allows the possibility of hard copy graphics output and it gives direct access to computer services such as databases, etc. Data prembles can also be used, in a selective calling mode, when initiating a transmission to address a special receiver and thus obtain more privacy within the system.15.4.5 Trunked radio for paramilitary use集群无线电的军事使用Another related TDMA mobile radio standard is the European trunked radio(TETRA)network which has been developed as part of the public safety radio communications service(PSRCS) for use by police, utilities, customs office, etc. TETRA in fact is part of wider international collaborations for paramilitary radio use.In these portable radios there is a need for frequency hopping (FH) to give an antieavesdropping capability and encryption for security of transmission to extend military mobile radio capabilities to paramilitary use, i.e. for police, customs and excise offices, etc. these capabilities are included in the multiband interteam radio for the associated public safety communications office in the USA while Europe has adopted the TETRA standard.TETRA is essentially the digital TDMA replacement of the analogue PMR systems. The TETRA standard has spectrum allocations of 380 to 400 and 410 to 430MHz, with the lower band used for mobile transmissions and the upper band for base station use. TETRA mobile have 1 W output power and the base stations 25 W using error with the data throughput rate varying, to meet the required quality of service. TETRA can accommodate up to four users each with a basic speech or data rate of 7.2kbit/s. with coding and signaling overheads, the final transmission rate for the four-user slot is 36 kbit/s. this equipment is large and more sophisticated than a commercial cell phone, and it sells for a very much higher price becase the production runs are much small. However, its advanced capabilities are essential for achieving paramilitary communications which are secure from eavesdropping.15.5 Code division multiple accessAnalogue communication systems predominantly adopt frequency division multiple access (FDMA), where each subscriber is allocated a narrow frequency slot within the available channel. The alternative TDMA(GSM) technique allocates the entire channel bandwidth to a subscriber but constrains the subscriber but constrains the subscriber to transmit only regular short bursts of wideband signal. Both these accessing techniques are well established for long haulterrestrial, satellite and mobile communications as they offer very good utilization of the available bandwidth.15.5.1The inflexibility of these coordinated accessing techniques has resulted in the development of new systems based on the uncoordinated spread spectrum concept. In these systems the bits of slow speed data traffic from each subscriber are deliberately multiplied by a high chip rate spreading code, forcing the low rate (narrowband data signal) to fill a wide channel bandwidth.15.7.2 3G systemsThe evolution of the third generation (3G)system began when the ITU produce the initial recommendations for a new universal mobile telecommunications system(UMTS)[www.] The 3G mobile radio service provides higher data rate services ,with a maximum data rate in excess of 2Mbit/s, but the achievable bit rate is linked to mobility. Multimedia applications encompass services such as voice, audio/video, graphics, data, Internet access and e-mail. These packet and circuit switched services have to be supported by the radio interface and the network subsystem.Several radio transmission technologies(RTT) were evaluated by the ITU and adopted into the new standard, IMT-2000. the European standardization body for 3G, the ETSI Special Mobile Group, agreed on a radio access scheme for 3G UMTS universal terrestrial radio access(UTRA) as an evolution of GSM. UTRA consists of two modes : frequency division duplex(FDD) where the uplink and downlink are transmitted on different frequencies; and time division duplex(TDD) where the uplink and downlink are time multiplexed onto the same carrier frequency. The agreement assigned the unpaired bands (i.e. for UTRA TDD ). TD-CDMA is a pure CDMA based system. Both modes of UTRA have been harmonised with respect to basic system parameters such as carrier spacing, chip rate and frame length to ensure the interworking of UTRA with GSM.The 3G proposal were predominantly based wideband CDMA(WCDMA) and a mix of FDD and TDD access techniques. WCDMA is favoured for 3G in poor propagation environments with a mix of high modest speed data traffic. It is generally accepted that CDMA is the preferred accesstechnique and, with the increase in the data rate, then the spreading modulation needs to increase to wideband transmission.WCDMA is based on 3.84Mchip/s spreading codes with spreading ratio, i.e. , K values, of 4-256 giving corresponging data ratas of 960-15 kbit/s. the upper FDD uplink band I from 1920-1980 MHz is paired with a 2110-2170 MHz downlink. In addition uplink bands II & III at 1850-1910 MHz and 1710-1785 MHz are also paired, respectively, with 1930-1990 MHz and 1805-1880 MHz allocations. the system is configured on a 10 ms frame with 15 individual slots to facilitate TDD as well as FDD transmissions. TDD is more flexible as time-slots can be dynamically reassigned to uplink and downlink functions, as required for asymmetric transfer of large files or video on demand traffic. 3G WCDMA systems use an adaptive multirate speech coder with encoded rates of 4.75-12.2 kbit/s. receivers commonly use the easily integrated direct conversion design, in place of the superheterodyne design . receiver sensitivities are typically -155dBm.The 3GPP2 standard aims to achieve a wide area mobile wireless packet switched capability with CDMA2000 1×EV DO revision A (sometimes called IS-856A). Here 1×refers to the single carrier 1.25 Mchip/s system. It achieves a 3.1 Mbit/s downlink and a delay sensitive services. The 3GPP standard has gone through many release with R4 in 2001 which introduced packet data services and R6 in 2005 to further increase the available data transmission rate . R6 pioneers the use of high-speed downlink packet access and multimedia broadcast multicast services which offer reduced delays and increased uplink data rates approaching 6 Mbit/s.In parallel with the European activities extensive work on 3G mobile radio was also performed in Japan. The Japanese standardisation body also chose WCDMA, so that the Japanese and European proposals for the FDD mode were already aligned closely. Very similar concepts have also been adopted by the North American standardization body.In order to work towards a global 3G mobile radio standard, the third generation partnership project(3GPP), consisting of members of the standardization bodies in Europe, the USA, Japan, Korea and China, was formed. It has merged the already well harmonized proposals of the regional standardization bodies to work on a common 3G international mobile radio standard, still called UTRA. The 3GPP Project 2(3GPP2), on the other hand, works towards a 3G mobile radio standard based on cdmaOne/IS-95 evolution, originally called CDMA2000.比起相对稳定、适度的技术发展是发生在宽带微波通信系统,有长期快速发展和扩大部署的新的移动个人通讯系统。

Unlocking the Climate Puzzle解开气候之谜(1)Life has prospered on this planet for nearly four billion years. In that time, climate had fluctuated drastically, from ice ages lasting tens of thousands of years to epochs of steamy heat. With each change, sundry species have benefited and flourished.Others adapted, faltered, or died. Now, many experts believe, humans are imperiling their own ecological niche with the threat of global warming. The vaporous by-products of civilization, in the form of greenhouse gases such as carbon dioxide (C0₂), have trapped enough heat in the atmosphere to raise Earth's average surface air temperature a half degree Celsius (one degree Fahrenheit) during this century. If the trend continues, it could alter climate patterns worldwide-thawing glaciers, boosting sea level, scorching plains into deserts, and shifting vegetation zones.(1)生命在这个星球上已经发展了近四十亿年。
Unit 1 EnvironmentEarth’s Health in Sharp Decline, Massive Study Finds大规模研究发现:地球的“健康”每况愈下The report card has arrived from the largest ever scientific Earth analysis, and many of the planet’s ecosystems are simply not making the grade.有史以来对地球进行的最大规模的科学分析结果表明,地球上的许多生态系统都达不到标准。
The UN-backed Millennium Ecosystem Assessment Synthesis Report found that nearly two-thirds of Earth’s life-supporting ecosystems, including clean water, pure air, and stable climate, are being degraded by unsustainable use.由联合国主持的《千年生态系统评估综合报告》指出,由于不可持续的使用,地球上将近三分之二的用来维持生命的生态系统(包括干净的水源、纯净的空气以及稳定的气候)正遭受破坏。
Human has caused much of this damage during the past half century. Soaring demand for food, fresh water, timber, fiber and fuel have led to dramatic environmental changes, from deforestation to chemical pollution, the report says. The already grim situation may worsen dramatically during the first half of the 21st century, the report’s authors warn.以上大部分的破坏都是人类在过去的半个世纪里造成的。
Teach Predictions for 20101. Finally, Apple Unveils the TabletOfficially, Apple has never said a word about making a tablet computer. Yet for months, everyone in tech has been talking and writing and arguing about the Apple tablet as if it's already here. The product has already received more press than most products that actually exist. Bloggers debate its faults and flaws, its strengths and Shortcomings--such is life in the weird and wonderful world of Apple. And this does not happen by accident. Apple orchestrates this stuff. It did the same thing with the iPhone, remember? For a year before the prodtict was unveiled, rumors circulated and fake prototype photos popped up all over the place. Ifs all about creating hype, and wrapping a product in a cloud of mystery and drama, so that by the time you do unveil it people are dying to buy it just tosee what all the fuss is about.The great thing about Apple, however, is that usually the products live up to the hype. Certainly the iPhone has. Arguably, it is the single most important tech product of the past decade. Will the tabletbe as profound? We think it will be. Amazon's Kindle has pioneered the market for a portable reading device. But Kindle is far from perfect. Our bet is that Apple enters this space the way it did with the iPod and iPhone: it lets others do the pioneering work and make all the mistakes, then comes along with a product that blows the predecessors away. Better design. Better build quality. Better service. And a user interface experience that’s light years ahead of everyone else's on the planet.2. Murdoch Pulls out of GoogleThe biggest, most powerful, and once-thought-to-be indestructible print media outlets have arrived at their moment of reckoning. For a decade, the likes of the Los Angeles Times, The Washington Post, and The New York Times (not to mention innumerable other oudets), have offered up their best work on a silver, online platter-- for free. Look at where it got them. The first is in jeopardy of closing up shop, the Post has shuttered its domestic bureaus, and the Gray Ladys just eliminated some 100 newsroom jobs, the second such move in two years. Enter Rupert Murdoch, theoutspoken Aussie head of News Corp whose empire spans from the Times of London to the most august business publication in the United States, The Wall Street Journal. For months now, he has been ranting about the free consumption of news online. His radical idea? Murdoch wants to stop Google from indexing his sites, and he wants Microsoft to pay for the privilege instead. In other words, he wants someone to pay for the stuff his journalists produce.A chorus of bloggers is crying that the old man's thinking cuts against the force of history--namely, that information wants to be free, and that any future-minded company ignores that fact at its peril. Techdirt says the news baron is a hypocrite. Boing Boing says Murdoch's threat to block searches and shroud his sites with paywalls is nothing more than a bluff. Think again. This isn't a doddering old coot who doesn't get the Web. Murdoch is a savvy business-man who just might lead an industry back into the reality-based community. With billions in cash on hand, he can afford short-term losses as his properties experiment with strategies that do not involve the essential untenability of giving the product away. And once he proves that a news publication can poke Google in the eye and survive, others will follow suit. After all, if they don't, Murdoch may be the only one left standing.3. Malw Disrupts FacebookWhen it comes to malware, the law of gravity is this: the bad guys go where the money is. That's why threats to computer users have evolved from viruses to botnets and phishing attacks--each iteration is more likely to produce profit. How does a piece of malware make money, exactly? In a number of ways, from rifling through your files for bank-account information and credit-card numbers, to turning your computer into a spam factory. The follow-the-money rule also helps explain why there aren't many threats for *Mac computers. They may have some security advantages over PCs, but mostly their market share isn't big enough to be worth malware creatorg time. )It follows that as we conduct more of our lives online, malefactors will follow us there. And where is the biggest action on the Web today? Facebook, which just signed up its 350 millionth user and shows no sign of slowing down. Facebook has seen malware before; the latest threat is an especially virulent edition of the "Koobface" worm that has bedeviled the social network for months. It's going to get worse from here. Facebook has a team of smart engineers dedicated to keeping malicious activity off the site, but with the network ballooning in size, they'll need to redouble their defenses in even greater proportion.4. Starbucks Will Stalk YouPrivacy is so passe. We've become addicted to broadcasting our lives to the world, and the mobile phone is our greatest enabler. That's especially true now that GPS is a standard feature. And today's hottest startups are racing to become the ankle bracelet of choice, doing everything they can to track our every move and indulge our shout-it-from-the-rooftops exhibitionism. Location-aware services like Foursquare, which awards points every time you check into a bar or restaurant, have become staples among the early-adopter crowd. Meanwhile, Twitter6 has added geolocation to its service, meaning each tweet is like a thumbtack on the map of your daily travels. Rumors have it that Facebook, with its 350 million users, is heading in the same direction. It's only a matter of time before advertisers follow. You can almost hear the screams of joy coming from marketing departments nationwide: soon companies will be able to target their ad campaigns based not just on who you are, but where you are. Passing by a Starbucks? Your phone just offered you 10 percent off a peppermint latte!5. Movie Downloads Stall Blu-rayBlu-ray may have won the war with its rival, HD-DVD---but does anyone care? While consumers were waiting for the two formats to duke it out--nobody wanted to plunk down several hundred bucks on a losing technology--they discovered that downloading movies to their homes has matured into a great way to watch their favorite titles. A Harris Interactive poll in June found that only 7 percent of consumers without Blu-ray players planned on buying one in the next year. Whafs holding back a format that everyone agrees is showstoppingly gorgeous to watch? Money is a big part of it, of course. Getting video over the Internet through iTunes9 or Amazon Video on Demand can be much cheaper than purchasing physical copies. Sometimes the value is truly insane: all it costs to binge out on seasons one, two, and three of Friday Night Lights is $ 8.99. That's the price of the cheapest monthly subscription to Netflix, which allows unlimited streaming of some shows and movies to your PC, or to your big screen if you own an Xbox 360, PlayStation 3, newer TiVo, or a similar device,Yes, a Blu-ray disk provides better quality picture and sound. But as Wired magazine argued in a recent cover story, consumers are enjoying a "Good Enough Revolution" : we're nuts about MP3s, even if they sound kind of crappy, and we can't watch enough YouTube clips, even though they're pixellated and choppy. The feverish pursuit of top quality is no longer our only concern. Sometimes convenience matters more.6. Your Phone Replaces Your WalletDuring its most recent pledge drive, the popular public-radio program This American Life followed a familiar script, exhorting its users to chip in $10, $ 5, even just $1, to help pay for its weekly broadcast. The pitch wasn't new, but one of the payment methods was instead of heading to your computer and entering your credit-card information, you could simply send $ 5 to the show via text message. Long promised, never realized, mobile payments will finally take off in the U. S. in 2010. Already the sector is a beehive of activity, with companies like Zong and mPayy enabling cus tomers to pay for online purchases with only a phone number. Obopay, another mobilepayments company, received $ 35 million from Nokia in 2009, and it will have a wide rollout on that company's phones. Perhaps the best sign that the sector is poised for takeoff is that Twitter creator and tech superstar Jack Dorsey has set his sights on it. His new company, Square, launched in December, allows merchants to accept credit-card payments with cell phones. True, Square doesn't untether us from plastic just yet, but it's only a matter of time before "Cash or credit?" becomes "Cash or cell?"7. Facebook Goes PublicAt only 25 years old, Facebook's Mark Zuckerberg has turned his donn-room idea into a global empire. Might he identify with Alexander the Great, who wept at the size of his dominion because there were no more lands left to conquer? Not just yet: he can still take the company public. In November, the social-networking company took a major step toward that event by announcing that it was creating two classes of stock: one class suitable for sale in an initial public offering, and one that is vested with 10 times the voting power. An IPO under those conditions would flood the company with cash while keeping control firmly in Zuckerbergs hands. If that sounds familiar, it's because the strategy is the same one used by Google before it went public in 2004. Zuckerberg is as cutthroat and super-ambitious as he is socially awkward that is to say, very--and he would stand to become an actual billionaire, not just a virtual one. His Personal wealth has yo-yo'd in line with various private valuations of his company over the years. Facebook also announced this year that it is cash-flow positive, and a successful IPO would cement the site as a viable business, while archrival Twitter stillscrambles for a business model.8. Twitter Use FlatlinesTwitter is almost synonymous with explosive growth. But there are signs that 2009's darling of the Internet has already begun to level off, a reversal that would have seemed impossible not long ago. In February 2oo9, Nielsen Online reported that Twitter's 7 million unique visitors constituted more than 1,000 percent growth in just a year's time. Ashton Kutcher, after beating CNN to the million-follower mark in a neckand-neck race, began blasting past later milestones with ease. (He's now at 4.1 million followers. ) And when Oprah Winfrey embraced the service in April, Twitter's popularity simply hockey-sticked.There were skeptics all along-- Nielsen also reported last spring that 60 percent of Twitter users failed to return after one month but excitement about the new mediurm's potential made them easy to dismiss. Now the data have become difficult to ignore. Twitters U. S. traffic actually declined from September to October, according to a range of measures. We're by no means Twitter haters--here's proof--but it seems clear that the service is in for a period of modest performance, as sign-ups of new users are measured against better estimates of existing users who neglect their accounts. One of the things that has made Twitter so successful is its wide-open API; ironically, that same transparency can provide a reality check on the number of people who have let their accounts go totally dormant who began tweeting during the Oprah bubble, but turned out to be making just a short stop at the birdbath.9. Microsoft Pushes Out Steve BallmerBallmer's 10th anniversary as CEO of Mierosoft arrives in January, but ifs hard to imagine he'll be celebrating. Mierosoft stock has dropped by nearly 50 percent on his watch, lagging not just other teeh eompanies but even the Dow Jones industrial average. Distracted by the Windows Vista fiasco, Ballmer has missed every big new tech market of the past decade. Google won the race for Internet search and keyword advertising. Apple won in MP3 players and online music sales, and now holds the high ground in mobile phones, while Windows Mobile fades away. Microsoft's Zune music player is a dud. Bing, Microsoft's search engine, will never catch Google. Ballmer is said to be a brilliant guy, but he got a black eye for the way he blundered and blustered and finally botched an attempted acquisition of Yahoo. He's a screamer and a bit of a bully--not the easiest guy to work for. If Microsoft were any other company, this guy would be in trouble. But the catch is, Ballmer was put into the job by Microsoft founder Bill Gates, and the two have been pals since their undergraduate days at Harvard. If Gates wants to get rid of Ballmer, he' 11 have to craft some kind of graceful exit that lets his buddy save face. Another problem: there's no heir apparent on the management team. Nevertheless, investors must be getting restless. Soon they'll start calling for a shake-up.10. Google Faces Antitrust SuitThe Feds are already looking at Google on a variety of fronts. Its deal with book publishers has drawn scrutiny. In 2009 it was hassled by the Federal Trade Commission over possible anticompetitive connections because it shared two board members with Apple, a situation that got resolved when Google CEO Eric Schmidt quit Apple's board, and Arthur Levinson, an Apple board member, quit the Google board. Regulators freaked out again when Google tried to make a search partnership with Yahoo. Supposedly the Feds were ready to bring charges, but then Google walked away from the deal.After facing this scrutiny in the past year, Google has launched a kind of ongoing publicity campaign, wooing the media and hoping to convince people that it isn't really a big bad company. It likes to say that it's operating in a highly competitive field and that its users can leave with the click of a mouse. But the fact is, Google handles two thirds of all searches in the United States. Whether that can legally be defined as a "monopoly" and whether Google can be shown to have abused its powerful market position remains to be seen. But regulators here and/or in the European Union will find Google so tempting a target that they will not be able to resist bringing a case to find out.Addicts of the Information AgeAmong everybody from our leaders to our teenagers, no habit is spreading faster than being connected 24/7 via a smart phone.[2] Its penetration in the U.S. is estimated at 18%, and it seems that everywhere you turn, people are using their smart phones in new ways and in new places. Samsung recently estimated that it expects 500 million global smart-phone users by 2012. Actual phone calls are becoming extinct compared with handheld texts and email messages--whoever thought people would prefer typing to talking? But the evidence appears to say they do.[3"] This has also given rise to a group of people--the top 10% of smart-phone users--who just can't stop. They are the smartphoniacsI, the true addicts of the information age.[4] Here are five tell-tale2 traits of Smartphoniacs :Do they take their smart phones with them when they get up from the table to go to the restroom---and do they take an awful lot of trips there?Do you receive messages from them while you know they are driving (increasingly being harmed in state after state), or at midnight on Saturday night?Do they come up with excuses in the middle of a conversation to pull out their smart phone--something like "let me jot something you said down so I don't forget it", and then sneak a look at all their messages?Are they suffering from sprained or elongated thumbs?Do they openly use their smart phones in inappropriate places, such as first dates, at Rosh Hashanah4 or Christmas dinner, in hospital delivery rooms, or on job interviews?[5 ] If your "friend" fits four out of five of these, then he or she is a smartphoniac. If he fits only two or three of them, he is just another typical user who stays connected on the street, in meetings and at the movies.[6] As these devices pop up everywhere, there has been a recent spate of articles about smart-phone "manners"--as if using your phone when your boss, or your mother, is talking to you is just a matter of poor training on their part. I don't think your boss or your mom ever said "go ahead, text while I'm talking to you". So it's just not a matter of manners. Ifs much more the result of a deeper disconnect anxiety, an irrepressible fear that you will miss something if you put it away.[7] I once worked with a candidate for Senate who emailed me from the podiums during a debate. Many 'CEOs communicate today primarily from their smart phones. Hillary Clinton and Barack Obama used them on the campaign trail, while John MeCain didn't.[8] The famed red phone to call the Russian premier in the event of a national security emergency could now be replaced by a red smart phone. Imagine if the world's top leaders were all connected bysmart phones and they communicated directly and frequently about issues of mutual concern. It would revolutionize diplomacy.[9] But Smartphoniacs are an eclectic mix of the successful and powerful, busy professionals, teenagers and college students. All of them commtmicate incessantly.[10] In Korea, more than three in 10 youths who carry mobile phones are said to be addicted. In Germany, there are an estimated 380,000 texting addicts—folks who withdraw from the very family and friends their machines were supposed to connect them to. While there hasn't been a formal study of Smartphoniacs in America, we know that between the second quarter of 2007 and the second quarter of 2008, the North American smart-phone market grew 78.7%. About 139.3 million smart phones were sold world-wide last year, and half of U. S. smart-phone users report using their devices more today than they did just three months ago.[11] Last month, the National Texting Championship award and its $ 50,000 grand prize went to a 15-year-old who texts 500 times a day. A recent poll found that 42% of teens can text with their eyes closed. And based on other studies on the intensity of smart-phone use, we can guess that Smartphoniacs skew male, affluent and well-educated. Not since the television has any invention changed the lifestyle habits of Americans more than the smart phone. The recent movie Seven Pounds detailed the guilt of an executive who caused a fatal car crash because he emailed while driving.[12] To be sure, there are forces calling for temperance7. Some people refuse to date people who use smart phones. Many parents just say no. Legislators are getting into the act to protect public safety. But for the most part, Americans of every age and stage are wrapping themselves in apps, chcks and instantaneous communication as part of a social network. And some small but significant percentage of this group is going to take a one-way slide to the bottom, where the compulsion to use their smart phones is so strong that they can only hope their batteries last long enough to text a cry for help.[13] We're not far away from Smartphoniacs Anonymous or Mothers Against Smart Phones. We've been through this with TV, the Intemet and videogames. In the end it all works out and we successfully integrate them into our lives, even though we are never again the same. At least with smart phones, with all their usage counters, we will be able to tell who has recovered from the binges.。
科技英语原文及简单翻译How ASIMO WorksIntroduction to How ASIMO WorksWant a robot to cook your dinner, do your homework, clean your house, or get your groceries? Robots already do a lot of the jobs that we humans don't want to do, can't do, or simply can't do as well as our robotic counterparts.Honda engineers have been busy creating the ASIMO robot for more than 20 years. In this article, we'll find out what makes ASIMO the most advanced humanoid robot to date.The Honda Motor Company developed ASIMO, which stands for Advanced Step in Innovative Mobility, and is the most advanced humanoid robot in the world. According to the ASIMO Web site, ASIMO is the first humanoid robot in the world that can walk independently and climb stairs.Rather than building a robot that would be another toy, Honda wanted to create a robot that would be a helper for people -- a robot to help around the house, help the elderly, or help someone confined to a wheelchair or bed. ASIMO is 4 feet 3 inches (1.3 meters) high, This allows ASIMO to do the jobs it was created to do without being too big and menacing.ASIMO's Motion: Walk Like a HumanHonda researchers began by studying the legs of insects, mammals, and the motion of a mountain climber with prosthetic legs to better understand the physiology and all of the things that take place when we walk -- particularly in the joints. For example, the fact that we shift our weight using our bodies and especially our arms inorder to balance was very important in getting ASIMO's walking mechanism right. The fact that we have toes that help with our balance was also taken intoconsideration: ASIMO actually has soft projections on its feet that play a similar role to the one our toes play when we walk. This soft material also absorbs impact on the joints, just as our soft tissues do when we walk.ASIMO has hip, knee, and foot joints. Robots have joints that researchers refer to as \degrees of freedom.\A single degree of freedom allows movement either right and left or up and down. ASIMO has 34 degrees of freedom spread over different points of its body in order to allow it to move freely. There are three degrees of freedom in ASIMO's neck, seven on each arm and six on each leg. The number of degrees offreedom necessary for ASIMO's legs was decided by measuring human joint movement while walking on flat ground, climbing stairs and running.ASIMO also has a speed sensor and a gyroscope sensor mounted on its body. They perform the tasks of:? ?sensing the position of ASIMO's body and the speed at which it is moving relaying adjustments for balance to the central computer These sensors work similarly to our inner ears in the way they maintain balance and orientation.ASIMO also has floor surface sensors in its feet and six ultrasonic sensors in its midsection. These sensors enhance ASIMO's ability to interact with its environment by detecting objects around ASIMO and comparing gathered information with maps of the area stored in ASIMO's memory.To accomplish the job our muscles and skin do in sensing muscle power, pressure and joint angles, ASIMO has both joint-angle sensors and a six-axis force sensor.Unless you know a lot about robotics, you may not fully grasp the incredible milestone it is that ASIMO walks as we do. The most significant part of ASIMO's walk is the turning capabilities. Rather than having to stop and shuffle, stop and shuffle, and stop and shuffle into a new direction, ASIMO leans and smoothly turns just like a human. ASIMO can also self-adjust its steps in case it stumbles, is pushed, or otherwise encounters something that alters normal walking.In order to accomplish this, ASIMO's engineers had to find a way to work with the inertial forces created when walking. For example, the earth's gravity creates a force, as does the speed at which you walk. Those two forces are called the \inertial force.\ground, called the \posture has to work to make it happen. This is called the \zero moment point\(ZMP). To control ASIMO's posture, engineers worked on three areas of control:? ?Floor reaction control means that the soles of the feet absorb floor unevenness while still maintaining a firm stance.Target ZMP control means that when ASIMO can't stand firmly and its body begins to fall forward, it maintains position by moving its upper body in the direction opposite the impending fall. At the same time, it speeds up its walking to quickly counterbalance the fall.?Foot-planting location control kicks in when the target ZMP control has been activated. It adjusts the length of the step to regain the right relationship between the position and speed of the body and the length of the step.ASIMO's Motion: Smooth MovesASIMO can sense falling movements and react to them quickly; but ASIMO's engineers wanted more. They wanted the robot to have a smooth gait as well as do something that other robots can't do -- turn without stopping.When we walk around corners, we shift our center of gravity into the turn. ASIMO uses a technology called \predictive movement control,\Intelligent Real-Time Flexible Walking Technology or I-Walk, to accomplish that same thing. ASIMO predicts how much it should shift its center of gravity to the inside of the turn and how long that shift should be maintained. Because this technolgy works in real time, ASIMO can do this without stopping between steps, which other robots must do.Essentially, with every step ASIMO takes, it has to determine its inertia and then predict how its weight needs to be shifted for the next step in order to walk and turn smoothly. It adjusts any of the following factors in order to maintain the right position:? ? ? ?the length of its steps its body position its speedthe direction in which it is steppingWhile reproducing a human-like walk is an amazing achievement, ASIMO can now run at speeds up to 3.7 miles per hour (6 kilometers per hour). In order to qualify as a true running robot, ASIMO must have both feet off the ground for an instant in each step. ASIMO manages to be airborne for .08 seconds with each step while running. Honda engineers encountered an entirely new set of challenges while trying to give ASIMO the ability to run. They gave ASIMO’s torso a degree of freedom to aid in bending and twisting so that the robot could adjust its posture while airborne. Without this ability, ASIMOwould lose control while airborne, possibly spinning in the air or tripping when landing.In order to make turns smoothly while running, the engineers enhanced ASIMO's ability to tilt its center of gravity inside turns to maintain balance and counteractcentrifugal force. ASIMO could even anticipate turns and begin to lean into them before starting the turn, much like you would if you were skiing or skating.ASIMO如何工作介绍如何工作。

科技英语新闻翻译MARGIE NEWMAN: "When you can go to a place and not only see what's next and see how to better use what's already here, but also connect with people who love it as much as you do, it's just kind of a special thing. A lot of people call South by Southwest Interactive the geek spring break. And that's pretty accurate."纽曼:“当你来到这里,不仅能看到下一个技术热点,了解如何更好的运用当前科技。
还可以和有着相同兴趣的人一起交流。
这是非常特别的经历。
很多人把SXSW盛典称为奇客春假(怪人云集),这是相当准确的。
South by Southwest Interactive has seen the successful launch of several products. It helped push Twitter into mainstream popularity in two thousand seven. In two thousand nine, a company called Foursquare launched its mobile networking service at the festival. The service lets friends tell other friends where they are by "checking in" using a mobile application or a text message. Foursquare's owners say they now have more than six and a half million users around the world.SXSW盛典见证了几个产品的成功推出。
2007年该盛典推动了Twitter的普及。
2009年,一家名为Foursquare的公司在SXSW盛典推出了手机网络服务。
这项服务允许朋友之间通过手机程序或短信“检入”(checking in)分享自己所处的地理位置。
Foursquare公司表示,现在他们在全球拥有超过650万用户。
Margie Newman says quick response codes are big news at this year's festival. The codes turn URLs and text into barcode-like images that can be scanned using a mobile phone or a QR code reader.出自VOA Special English Technology ReportA shortwave radio might seem like ancient technology these days. But for some people, it remains their only link to the wider world.短波收音机如今看来可能像是一种很古老的技术。
但对一些人来说,短波收音机仍是他们与外界联系的唯一工具。
Ears to Our World is an organization based in the United States. It provides shortwave radios to schools and communities in some of the poorest areas of the world.“聆听世界”(Ears to Our World)是一家总部位于美国的组织。
该组织为世界上一些最贫穷地区的学校和社区提供短波收音机。
The radio is small, about the size of a book, and self-powered. Users turn a crank. Winding it for two minutes provides about forty minutes of listening time.这种收音机体积非常小,只有一本书大小。
收音机自身可以发电,用户打开发电手柄摇转2分钟,就能提供40分钟的收听时间。
Ears to Our World is supported by private donations and partners including Eton, the company that makes the Eton Grundig radios.“聆听世界”由私人捐助的支持,其合作伙伴包括制造根德(Grundig)收音机的伊顿公司。
Thomas Witherspoon started Ears to Our World in two thousand eight.托马斯·威瑟斯朋2008年创办了“聆听世界”组织。
THOMAS WITHERSPOON: "Our radios are going to people who have no other source of international news and information. It's hard for them to learn new languages and be connected to the bigger world.威瑟斯朋:“我们的收音机提供给了没有渠道获取国际新闻资讯的人们。
对他们而言,学习新语言并和世界保持联系非常困难。
"In fact, in a lot of these communities, the feedback we get is before they had their radio, most of their news and information came word of mouth, from other people. So this way they're getting more accurate information. And teachers use this information in the classroom to enhance a student's learning ability about the world around them."“事实上,我们从大部分社区得到的反馈信息是,在他们得到收音机以前,他们大部分新闻资讯是通过他人之口传来的。
因此通过收音机他们能得到更多确切信息。
而老师们也能在课堂上利用这些信息,增强学生们对周边世界的学习能力。
”Ears to Our World works with local organizations to get the radios to where they are needed most. Mr. Witherspoon says the radios are now in eleven communities, most of them in Africa.“聆听世界”组织与当地组织合作将收音机送到最需要的地方。
威瑟斯朋先生说,这些收音机现在提供给了11个社区,这些社区大部分在非洲。
He says many of these communities are unable to get information any other way.他说,这些社区中的大多数无法通过其他方式获得信息。
THOMAS WITHERSPOON: "We take our radios to parts of the world that lack access to the Internet, to a national power gridof any sort. We're talking about places maybe in South Sudan that are very, very remote. No one in the community or the village has power in their homes."威瑟斯朋:“我们把收音机送到了世界上部分没有互联网和任何电力网的地区。
我们提到的也许就在南苏丹非常、非常遥远的地区。
这些社区或村庄的人们家里都没有电。
”Thomas Witherspoon says information is the most important tool to improve the lives of poor people.威瑟斯朋表示,信息是改善穷人生活最重要的工具。
THOMAS WITHERSPOON: "In this economy, information is sort of the lifeline for all of us to function and get along. Especially if you're living in a place where you have no information, information is your way out of poverty."威瑟斯朋:“在当今经济环境中,信息是我们所有人工作与生活的生命线。
特别是在缺乏信息的地区,信息是人们的脱贫途径。
”The self-powered radios are also useful in emergencies. Teachers in Haiti used them to get information after last year's earthquake.这种自供电收音机在紧急情况下也非常有用。
海地的老师们在去年的地震后就使用这种收音机获取信息。
Mr. Witherspoon says Ears to Our World has sent out about one thousand two hundred radios. More than half have gone to earthquake victims, mostly in Haiti. About five hundred have gone to individual teachers and schools.威瑟斯朋先生说,“聆听世界”组织已经发放了大约1200台收音机。
