Computer crime can broadly be defined as criminal activity involving an information technology infrastructure, including illegal access (unauthorized access), illegal interception (by technical means of non-public transmissions of computer data to, from or within a computer system), data interference (unauthorized damaging, deletion, deterioration, alteration or suppression of computer data), systems interference (interfering with the functioning of a computer system by inputting, transmitting, damaging, deleting, deteriorating, altering or suppressing computer data), misuse of devices, forgery (ID theft), and electronic fraud.Internet enables person-to-person communication is closer, faster. Ancient, live in Dongguan of you wanted to wrote to Beijing of relatives, that will to letter climb mountain wading with horse sent past, less is a months, more is a years; in modern, you can playing calls, but price expensive, also cannot transfer file or pictures; now, has has Internet, we can through QQ, and E-mail, way with distance of relatives communication, with United States of customer contact, chat a hours is just spent 1 Yuan around, and also can with video phone, people and people Zhijian of distance on became increasingly near has. However, the Internet also has a lot of bad places, it transformed, becomes best weapons to criminals. Criminals use the Internet to this vast and virtual world, to carry out criminal activities. They dressed in protective clothing of the Internet so that people can see their ugly heart. Newspapers often reported "QQ cheated on a woman was killed in XX", this is a hard fact. In addition, there are many "hacker", they spread the virus everywhere, so that greatly reduced the speed of the Internet, seriously blocked the Internet highway. More abominable is some unscrupulous Web sites on the Internet pictures, words such as pornography, violence, serious harm to people"s hearts. In today"s society, the Internet gives us a limitless expanse of land, in this land growing on you and friends and do not make this land abandoned, let it work out great fruit!

A clutch is a mechanical device that provides for the transmission of power (and therefore usually motion) from one component (the driving member) to another (the driven member) when engaged, but can be disengaged.Clutches are used whenever the transmission of power or motion must be controlled either in amount or over time (e.g., electric screwdrivers limit how much torque is transmitted through use of a clutch; clutches control whether automobiles transmit engine power to the wheels).In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to a motor or other power unit (the driving member) while the other shaft (the driven member) provides output power for work. While typically the motions involved are rotary, linear clutches are also possible.In a torque-controlled drill, for instance, one shaft is driven by a motor and the other drives a drill chuck. The clutch connects the two shafts so that they may be locked together and spin at the same speed (engaged), locked together but spinning at different speeds (slipping), or unlocked and spinning at different speeds (disengaged).The vast majority of clutches ultimately rely on frictional forces for their operation. The purpose of friction clutches is to connect a moving member to another that is moving at a different speed or stationary, often to synchronise the speeds, and/or to transmit power. Usually as little slippage (difference in speeds) as possible between the two members are desired.MaterialsVarious materials have been used for the disc friction facings, including asbestos in the past. Modern clutches typically use a compound organic resin with copper wire facing or a ceramic material. A typical coefficient of friction used on a friction disc surface is 0.35 for organic and 0.25 for ceramic. Ceramic materials are typically used in heavy applications such as racing or heavy-duty hauling, though the harder ceramic materials increase flywheel and pressure plate wear.Push/PullFriction disk clutches generally are classified as push type or pull type depending on the location of the pressure plate fulcrum points. In a pull type clutch, the action of pressing the pedal pulls the release bearing, pulling on the diaphragm spring and disengaging the vehicle drive. The opposite is true with a push type, the release bearing is pushed into the clutch disengaging the vehicle drive. In this instance, the release bearing can be known as a thrust bearing (as per the image above).DampersA clutch damper is a device that softens the response of the clutch engagement/disengagement. In automotive applications, this is often provided by a mechanism in the clutch disc centres. In addition to the damped disc centres, which reduce driveline vibration, pre-dampers may be used to reduce gear rattle at idle by changing the natural frequency of the disc. These weaker springs are compressed solely by the radial vibrations of an idling engine. They are fully compressed and no longer in use once the main damper springs take up drive.LoadMercedes truck examples: A clamp load of 33 kN is normal for a single plate 430. The 400 Twin application offers a clamp load of a mere 23 kN. Bursts speeds are typically around 5,000 rpm with the weakest point being the facing rivet.ManufacturingModern clutch development focuses its attention on the simplification of the overall assembly and/or manufacturing method. For example drive straps are now commonly employed to transfer torque as well as lift the pressure plate upon disengagement of vehicle drive. With regard to the manufacture of diaphragm springs, heat treatment is crucial. Laser welding is becoming more common as a method of attaching the drive plate to the disc ring with the laser typically being between 2-3KW and a feed rate 1m/minute.Multiple plate clutchThis type of clutch has several driving members interleaved or "stacked" with several driven members. It is used in race cars including F1, IndyCar, World Rally and even most club racing, motorcycles, automatic transmissions and in somediesel locomotives with mechanical transmissions. It is also used in some electronically controlled all-wheel drive systems as well as in some transfer cases.

It would be foolhardy to venture technological predictions for 2050. Even more so to predict social and geopolitical changes. The most important advances, the qualitative leaps, are the least predictable. Not even the best scientists predicted the impact of nuclear physics, and everyday consumer items such as the iPhone would have seemed magic back in the 1950s.But there are some trends that we can predict with confidence. There will, barring a global catastrophe, be far more people on Earth than today. Fifty years ago the world population was below 3 billion. It has more than doubled since then, to 6.7 billion. The percentage growth rate has slowed, but it is projected to reach 9 billion by 2050. The excess will almost all be in the developing world where the young hugely outnumber the old.If population growth were to continue beyond 2050, one can"t be other than exceedingly gloomy about the prospects. And the challenge of feeding such a rapidly growing population will be aggravated by climate change.The world will be warmer than today in 2050; the patterns of rainfall and drought across the world will be different. If we pursue "business as usual",CO2 concentration levels will reach twice the pre-industrial level by around 2050. The higher its concentration, the greater the warming - and, more important still, the greater the chance of triggering something grave and irreversible: rising sea levels due to the melting of Greenland"s icecap; runaway release of methane in the tundra.Some technical advances - information technology, for instance - surprise us by their rapidity; others seemingly stagnate. Only 12 years elapsed between the launch of Sputnik and Neil Armstrong"s "one small step" on the moon. Many of us then expected a lunar base, even an expedition to Mars, within 30 years. But it"s more than 36 years since Jack Schmitt and Eugene Cernan, the last men on the moon, returned to Earth. Since that time, hundreds of astronauts have been into orbit, but none has ventured further.The Apollo programme now seems a remote historical episode: young people all over the world learn that America landed men on the moon, just as they learn that the Egyptians built the pyramids; the motivations seem almost as bizarre in the one case as in the other. The race to the moon was an end in itself - a magnificent "stunt", driven by superpower rivalry. Thereafter, the impetus for manned flight was lost. But, of course, we now depend on space in our everyday lives (GPS, weather forecasting and communications). And robotic exploration has burgeoned. Unmanned probes to other planets have beamed back pictures of varied and distinctive worlds.I hope that by 2050 the entire solar system will have been explored and mapped by flotillas of tiny robotic craft. Robots and "fabricators" may enable large construction projects, using raw materials that need not come from Earth. But will people follow them? The practical case for sending people into space gets ever-weaker with each advance in robots and miniaturisation. But I"m nonetheless an enthusiast for manned missions - to the moon, to Mars and even beyond - simply as a long-range adventure for (at least a few) humans.Each mobile phone today has far more computing power than was available to the whole of Nasa in the 1960s. And advances proceed apace. Some claim that computers will, by 2050, achieve human capabilities. Of course, in some respects they already have. For 30 years we"ve been able to buy calculators that can hugely surpass us at arithmetic. IBM"s "Deep Blue" beat Kasparov, the world chess champion. But not even the most advanced robot can recognise and move the pieces on a real chessboard as adeptly as a five-year-old child.Deep Blue didn"t work out its strategy like a human player: it exploited its computational speed to explore millions of alternative series of moves and responses before deciding an optimum move. Likewise, machines may make scientific discoveries that have eluded unaided human brains - but by testing out millions of possibilities rather than via a theory or strategy.But will we continue to push forward the frontiers, enlarging the range of our consensual understanding? Some aspects of reality - a unified theory of physics, or a theory of consciousness - might elude our understanding simply because they"re beyond the powers of human brains, just as surely as quantum mechanics would flummox a chimpanzee.We can with some confidence predict continuing advances in computer power, in IT, in techniques for sequencing and interpreting and modifying the genome. But there could, by 2050, be qualitatively new kinds of change. For instance, one thing that"s been unaltered for millennia is human nature and human character. But in this century, mind-enhancing drugs, genetics, and "cyborg" techniques may start to alter human beings themselves.And we should keep our minds open, or at least ajar, to concepts on the fringe of science fiction. Flaky American futurologists aren"t always wrong. They remind us that a superintelligent machine is the last instrument that humans may ever design - the machine will itself take over in making further steps. Another speculation is that the human lifespan could be greatly extended, something that would wreak havoc on all population projections. At the moment this hope leads some to bequeath their bodies to be "frozen" on their death, in the hope of some future resurrection. For my part, I"d still opt to end my days in an English churchyard rather than a Californian refrigerator.We can make one firm forecast that"s important for all "citizen scientists". There will surely be a widening gulf between what science enables us to do, and what applications it"s prudent or ethical to pursue.It"s sometimes wrongly imagined that astronomers, contemplating timespans measured in billions, must be serenely unconcerned about next year, next week and tomorrow. But a "cosmic perspective" actually strengthens my own concerns about the here and now.Ever since Darwin, we"ve been familiar with the stupendous timespans of the evolutionary past. But most people still somehow think we humans are necessarily the culmination of the evolutionary tree. No astronomer could believe this.Our sun formed 4.5bn years ago, but it"s got 6bn more before the fuel runs out. And the expanding universe will continue - perhaps for ever - becoming ever colder, ever emptier. As Woody Allen said, "Eternity is very long, especially towards the end". Any creatures who witness the sun"s demise, here on Earth or far beyond, won"t be human. They will be entities as different from us as we are from a bug.But even in this "concertinaed" timeline - extending millions of centuries into the future, as well as into the past - this century is special. It"s the first in our planet"s history where one species - ours - has Earth"s future in its hands, and could jeopardise not only itself, but life"s immense potential.Suppose some aliens had been watching our planet for its entire history. Over nearly all that immense time - 4.5bn years - Earth"s appearance would have altered very gradually. But in just a tiny sliver of its history - the last few thousand years - the patterns of vegetation altered much faster than before. This signalled the start of agriculture. The pace of change accelerated as human populations rose.Then there were other changes, even more abrupt. Within the last 50 years - little more than one hundredth of a millionth of the Earth"s age - the carbon dioxide in the atmosphere began to rise anomalously fast. The planet became an intense emitter of radio waves (TV, cellphone, and radar transmissions.) And something else unprecedented happened: small projectiles launched from the planet escaped the biosphere. Some were propelled into orbits around the Earth; some journeyed to the moon and planets.If they understood astrophysics, the aliens could confidently predict that the biosphere would face doom in a few billion years when the sun flares up and dies. But could they have predicted this unprecedented spike less than halfway through the Earth"s life - these human-induced alterations occupying, overall, less than a millionth of the elapsed lifetime and seemingly occurring with runaway speed?If they continued to keep watch, what might these hypothetical aliens witness in the next few decades? Will final spasm be followed by silence? Or will the planet itself stabilise? And will some of the objects launched from the Earth spawn new oases of life elsewhere?The outcome depends on political choices. But those choices can be influenced by effective and idealistic scientists, environmentalists and humanists, guided by the knowledge and technology that the 21st century will offer.自不量力地对2050年作技术预测是愚蠢的尝试。打算预测社会和地理政治的变化更是自不量力。事实上，最重要的发展，最重要的质的跨越，也是最不可能预言的。即使是最优秀的科学家也没预料到核物理的冲击力如此巨大，而回溯到上世纪五十年代，像iPhone这样的日常消费品一定会被看作不可思议的东西。不过，我们能满怀信心地预言某些趋势。比如，除非爆发一场全球性大灾难，将来地球上一定会有比今天多得多的人口。五十年前，地球人口还不到三十亿；而五十年后的今天，地球人口已经翻了一番多，达到六十七亿。虽然人口增长的速度已经减缓，但是，由此类推，到2050年地球人口将达到九十亿，而且新增加的人口几乎都将出自发展中国家，因为现在那里年轻人的数量远远超过了老年人。如果2050年之后人口继续增长，那么前景无疑会极其暗淡。由于气候变化的影响，要养活如此迅速增长的人口，我们必将面临更加严峻的考验。到2050 年，全球气候将比今天更暖和；世界各地的降雨及干旱的形式也将有所变化。如果我们继续“处之泰然”，到2050年左右，大气中二氧化碳的浓度级别将达到工业化以前的两倍。而二氧化碳的浓度越高，气温就会越高——更重要的是，还可能引发某些更严重、更不可逆转的变化：格陵兰冰盖的融化造成海平面上升；冻土地带的甲烷失去控制释放出来。如今，某些技术（比如信息技术）的发展速度快得令人吃惊；而其它方面却似乎停滞不前了。苏联发射史波尼克人造卫星和尼尔·阿姆斯壮在月球上迈开“一小步”前后只过了十二年。我们许多人因此都期待着在三十年内完成月球基地的建设，甚至实现火星探险。然而，自从杰克 ·施密特和尤今·塞尔南最后登上月球又返回地球以来，已经过去三十六年多了。从那时起，已经有数百名宇航员进入轨道，但是，没有人再做进一步的尝试。阿波罗计划如今看起来如同遥远的历史事件：全世界的年轻人听美国人登陆月球的故事，就好像听埃及人建造金字塔的故事一样；其动机无外乎是为了在一个又一个事件中猎奇。其实争先恐后地登上月球才是登陆月球的真正目的——这不过是受超级大国相互竞争驱使的壮丽的“特技”表演。从那以后，载人飞行的动力就消失了。当然了，我们今天的日常生活，比如GPS，天气预报和通讯等都离不开太空。机器人的探险活动已经迅速发展起来。针对其它星球的无人驾驶探测器也已经传回各种各样独特世界的图片。我希望，到2050年，各种微型小机器人飞行器能够完成对整个太阳系的探测，并绘制出图谱。机器人和“制造者”也许能够使利用必要的非地球产原材料来建造大型建筑项目成为现实。可是，人们会遵照执行吗？把人送上太空的实际情况，使得机器人和小型化的每次改进都更缺乏说服力。尽管如此，我依然热心支持把载人飞行——去月球、去火星，甚至其它星球——仅仅作为人类（至少几个人）的远程冒险。如今，每部移动电话的计算能力都比二十世纪六十年代整个美国宇航局可用的计算能力都强得多。移动电话的发展进程非常迅速。有人声称，计算机将在 2050年之前达到人的智力水平。其实，在某些方面它们无疑已经达到了人的智力水平。早在三十年前，我们就能够买到计算能力大大超过人类的计算器。IBM 的“深蓝”计算机就打败了国际象棋世界冠军卡斯帕罗夫。但是，即使是现在最先进的机器人，也还不能像五岁大的孩子一样熟练地识别或移动现实生活中棋盘上的棋子。“深蓝”并不是像人类棋手那样计算棋着，而是利用自己快速的计算能力研究数百万条走法以及对策，再从中选定最佳的走法。同样，机器也能获得令人类大脑无法理解的科学发现，不过，它不是通过什么理论或策略，而是通过测试数百万条的可能性来完成任务的。那么，我们是否能够继续推进这些尖端科学，扩大我们的交感理解力范围呢？现实的某些方面，比如，我们难以理解物理的统一理论或认知理论，也许只是因为它们超出了人类大脑的理解能力，正如量子力学必定会令黑猩猩大惑不解一样。我们能颇为自信地预言计算机的性能、IT、技术等将继续发展，可以用于为基因组测序，理解并修改基因组。但是，至2050年，定然会出现新的变化。举例来说，人类的本性和人类的性格千年以来没有变化。而在本世纪，增智药物、基因和“半机器人”技术也许会开始改变人类本身。我们应该向处于科学幻想边缘的观念开放我们的头脑，或至少是半开放。古怪的美国未来学家也有对的时候。他们提醒我们，具有超常智慧的机器是人类所能设计的终极仪器——机器将接管其本身以后的发展历程。还有一种推测，即人类的寿命将大大延长，这将对各种人口预测造成巨大的破坏性影响。目前，这种希望已经导致一些人留下遗言，要将他们的尸体“冷冻起来”，希望将来能够复活。至于我，宁愿选择在英国的教堂结束自己的一辈子，也不想进入加利福尼亚的冰箱。我们能够确切地做出一个对所有“科学家公民”而言很重要的预言。那就是，科学能让我们做什么和科学所追求的明智或道德的应用之间肯定存在着宽大的鸿沟。有时，人们会错误地想像，以数十亿的标准来衡量时间间隔的天文学家们一定很冷静，不会在乎明天、下周甚至明年。但是，“宇宙的观念”确实加深了我自己对眼前的关注。自达尔文以来，我们已经熟悉了进化历史惊人的时间间隔。然而，不知为什么，大多数人仍然以为我们人类必然是进化树的顶点。而天文学家没人相信这一点。我们的太阳形成于四十五亿年前，而六十亿年后它的燃料才能耗尽。膨胀的宇宙将继续——也许会永远——越变越冷、越变越空。正如伍迪·艾伦所说，“永远是很长的，尤其是通往终结”。任何能见证太阳死亡的生物，无论是在当今的地球上或是遥远的它方，都不会是人类。它们将是某种实体，其不同于我们，就好像我们不同于臭虫一样。不过，即使在这张向未来，向过去延伸数百万世纪的“折叠式”时间表上，本世纪也是特别的一个世纪。在我们地球的历史上，这是第一次有一个物种——我们的人类——掌握了地球的未来，不仅可能危及其本身，而且可能危及生命的巨大潜力。假设某些外星人一直观察着我们地球的整个历史。随着那段极长的时间过去——四十五亿年——地球外貌必定一直都在逐渐地改变着。但是，在其历史的一小段时间内——即过去的几千年——植物的模样比以前变化得快得多。这标志着农业的出现。随着人类数量的增长，这种变化的速度也越来越快。接着，出现了其它变化，更突然的变化。在过去的五十年里 ——只比百万分之一地球年龄的百分之一多一点——大气中的二氧化碳浓度开始反常地迅速上升。地球成了无线电波（电视、手机以及雷达传输器）的密集发射器。另外一些前所未有的事情也发生了：从地球上发射出去的小型抛射体逃离了我们的生物圈。其中一些被推入环绕地球的轨道，另一些则飞向月球和其它星球。如果外星人懂得天体物理学，他们可能会自信地预测到，当太阳突然燃烧起来然后灭亡的时候，这个生物圈将在几十亿年之内面对厄运。他们会不会已经预测到地球生命过去了一半的信号？——总的来说，这些人类引发的变化占据了不到百万分之一已经过去的生命期，而表面来看却似以失控的速度在发生着变化。如果这些假设的外星人继续监视着我们，他们在今后几十年内会见证到什么？会是在最后的痉挛之后归于静寂吗？或者地球本身将稳定下来？从地球上发射出去的某些东西会不会在其它地方孕育出新的生命绿洲？这个结果取决于政治选择。而二十一世纪将要提供的知识和技术，可能会引导有影响、有理想的科学家、人类生态学专家和人类学者，对这些选择产生影响。

首先，需要先明确，绑定的各种模式0 - Sets a round-robin policy for fault tolerance and load balancing. Transmissions are received and sent out sequentially on each bonded slave interface beginning with the first one available.1 - Sets an active-backup policy for fault tolerance. Transmissions are received and sent out via the first available bonded slave interface. Another bonded slave interface is only used if the active bonded slave interface fails.2 - Sets an XOR (exclusive-or) policy for fault tolerance and load balancing. Using this method, the interface matches up the incoming request"s MAC address with the MAC address for one of the slave NICs. Once this link is established, transmissions are sent out sequentially beginning with the first available interface.3 - Sets a broadcast policy for fault tolerance. All transmissions are sent on all slave interfaces.4 - Sets an IEEE 802.3ad dynamic link aggregation policy. Creates aggregation groups that share the same speed and duplex settings.

International business environment for international business activities with a significant impact on the cultural environment which has an even smaller see the status of a concentrated expression of the culture of a country in the people"s basic beliefs and values. It not only affects multinational enterprises operating and management style, but also to the international business strategy have an important impact on decision-making. For example: China"s famous "white elephant" brand batteries, White Elephant translated into English, although the semantic information such as the good, but information on the culture, such as it is worse of the translation, because the white elephant in western countries means that "there is no Instead of using cumbersome things. " This meaning from a legend. Legend has it there was a king of his dislike of a minister, in order to punish him, the king gave the minister a white elephant. The Minister found that this is very difficult as the first, because it gave him the king, he is not transmitted to others, much less killed, but a carefully Shihou it. But the appetite for great white elephant of the Minister to eat poorer. So, I am afraid that the English-speaking countries who will not buy the brand for the White Elephant batteries, and because consumers are reluctant to buy, "but did not use the cumbersome things." Well. "White elephant" brand batteries should be how to translate? We can consider using a powerful symbol of the minds of Westerners, has the power to replace the animal lion, "white elephant" to Brown Lion. If the battery power purchased unparalleled customer Why not go ahead? China"s enterprises in the international cross-cultural business in the course of business has always been a diverse and heterogeneous cultural environment. Especially in the economically developed countries and the Western economic exchanges between the East and West cultural differences and the cultural differences between regions will be in the international business reflected in the economic operation, or even a business conflict. Therefore, the cross-cultural impact of China"s enterprises has become an international business activities in the one important factor that sometimes is the deciding factor. Take effective measures, the international business operations of the cultural activities to minimize conflict, the participation of Chinese enterprises in the process of international economic competition, not only to adapt to the international business activities between the main economic environment, better adapted to each other"s culture environment, and gain a competitive edge and access to the international business activities of the initiative, so that China"s enterprises to cross-cultural activities in the international economy must attach importance to and worthy of research. The World Trade Organization and regional economic integration Union, as well as transport and the rapid development of information technology and progress in the world economy and the scope of international business contacts and more space to expand. World economic and cultural integration of the trend of economic performance as a cultural and economic culture, and culture and the economy of mutual infiltration and influence. Another impact on the international business community to cultural factors make the concept of time. In a number of European culture, punctuality is very important, and in some other culture, late it can be acceptable. Similarly, in some American culture, the time is not a very strong constraints, in fact, until they can be accepted. A culture of the concept of time may help multinational companies engaged in business activities, such as: the Japanese often after a long period of consideration before reaching a decision. But once they made a decision, the timetable will be completed as scheduled tasks. In many Western culture is just the opposite, people decisions will be made soon, but action is very slow. Therefore, for those who prefer the rapid implementation of the enterprises, the Oriental culture better

We propose a suit of techniques andstrategies imported from other research areas that can be applied to design energy-efficient protocols in sensor networks. They includetime series forecasting, quorums systems, and the interaction between sensor properties and protocol design. We apply these techniques to the time synchronization problem, to efficiently collecting data from a sensor network, and to ensuring stronger data consistency guarantees in mobile networks.We show in [1,2,3,4] that time series forecasting techniques, and in particular autoregressive (AR) models, can be applied to sensor networks to conserve energy. We study a simple type of time series models with a short prediction window. We have chosen this model because it is capableof predicting data produced by real-world sensors measuring physical phenomena, and it is computationally tractable on modern-generation sensor networks. We apply these models to solve two relevant problems in sensor networks: the problem of efficiently collecting sensor data at the sink, and the time synchronization problem.We propose an energy-efficient framework, called SAF Similarity--based Adaptable query Framework [1,2] ), for approximate querying and detecting outlier values in sensor networks. The idea is to combine local AR models built at each node into a global model stored at the root of the network(the sink) that is used to approximately answer user queries. Our approach uses dramatically fewer transmissions than previous approximate approaches by using AR models and organizing the network into clusters based on data similarity between nodes. Our definition of data similarity is based on the coefficients of the local AR models stored at the sink, which reduces energy consumption over techniques that directly compare data values, and allows us to derive an efficient clustering algorithm that is provably optimal in the number of clusters formed by the network. Our clusters have several interesting features that make them suitable also for mobile networks: first, they can capture similarity between nodes that are not geographically adjacent; second, cluster membership adapts at no additional cost; third, nodes within a cluster are not required to track the membership of other nodes in the cluster. Furthermore, SAF provides provably correct error bounds and allows the user to dynamically tune answer quality to answer queries in an energy and resource efficient manner.In addition, we apply the AR models to solve the time synchronization problem from a novel perspective which is complementary to the well-studied clock synchronization problem [3,4]. More precisely, we analyze the case in which a sensor node decides to skip one or more clock adjustments to save energy, or it is temporarily isolated, but still requires an accurate estimate of the time. We propose a provably correct clock method based on AR models, which returns a time estimate within a constant (tunable) error bound and error probability. This method is highly adaptable and allows the sensor to decide how manyclock adjustments it can skip while maintaining the same time accuracy, thus saving energy. In addition, we propose a suit of deterministic methods that reduce the time estimation error by at least a factor 2. More precisely, we propose a provably correct deterministic clock reading method, called the DCR method, which exploits information regarding the sign of the clock deviation, and can be applied to reduce by half the frequency of the periodic clock adjustments, while maintaining the same error bound [3,4]. This method is of both practical and theoretical interest. In fact, it leads to a noticeable energy saving, and shows that a stronger but realistic clock model can lead to a refinement of the optimality bound for the maximum deviation of a clock that is periodically synchronized. In addition, we propose a generalized version of the DCR method that enhances its accuracy depending on the clock stability, and a method that guarantees the monotonicity of the time values produced.We analyze for the first time quorum system techniques in the context of sensor networks: we redesign them and show their benefits in terms of energy consumption [6]. Quorum systems have the potential to save energy in sensor networks since they can reduce noticeably the amount of communication, improve the load balance among sensor nodes, and enhance the scalability of the system. However, previous quorum systems and quorum metrics, proposed for wired networks, are unsuitable for sensor networks since they do not address their properties and limitations. These observations have motivated us to redesigning quorum systems and their metrics, taking into account the limitations and characteristics of sensors (e.g., transmission costs, limited energysource, physical radio broadcast), and the network topology. More precisely, we redefine the following quorum metrics: load balance, access cost and quorum capacity, and devise some strategies based on some characteristics of sensor networks that reduce the amount of communication when designing quorum systems for sensor networks. We apply these strategies to design a family of energy-efficient quorum systems with high resiliency. In particular, we propose a quorum construction that reduces the quorum access cost, and propose an energy-efficient data diffusion protocol built on top of it that reduces the energy consumption by reducing the amount of transmissions and collisions.In addition, we analyze quorum systems in case of high node mobility. More precisely, we study the difficult problem of guaranteeing the intersection between two quorums in case nodes move continuously along unknown paths [7]. We address this problem by defining a novel mobility model that provides a minimum set of constraints sufficient to derive strong data guarantees in highly mobile networks. Also in this case, we show the unsuitability of previous quorum systems, and provide a condition which is necessary to guarantee data availability and atomic consistency under high node mobility. We propose a new classof quorum systems, called Mobile Dissemination (MD) quorums, suitable for highly mobile networks, and propose a quorum construction which is optimal with respect to the quorum size (i.e., message transmissions) [7]. Then, we apply the MD quorum system to implement a provably correct atomic read/write shared memory for mobile and sparse networks.Bibliography [1] D. Tulone, S. Madden.

认知无线电用于一个网络的动态频率分配必须有效地运作中存在的不确定性和变化中的传播特点的网络的通讯连接。一个低复杂性的自适应传输协议描述和评价，使用认知无线电网络的联系不是很明了，有可能随时间变化的传播损失由于这种现象的衰落或阴影的变化。.认知无线电设备都要求接收器获得简单的统计数字，，以便提供我们协议需要的信息，没有估计或测量接收功能或渠道使用。.该协议的主要机制是应付变化的传输损耗来调整编码和调幅。由于中断，可能造成的更高水平的干扰到其他的无线电网络，发射机功率增加，只有最强大的组合编码和调幅是不够的。我们采用有限状态马尔可夫模型的不同渠道，我们声明我们的协议执行将近一个理想的协议，告诉每个数据包传输的传输损耗确切价值。因此，额外的复杂性需要使认知无线电通讯设备以获取准确的渠道获得的估计是没有道理的，并将导致只有微不足道的改善及通道通过量。通道通过量的自适应传输协议是与一个来自信息理论的一个假设的理想的协议上限给予完善的渠道状态信息，以及一些初步的结果对学习的适应决策的间隔也包括在内翻译的不知如何？专业的东西很费劲的。希望对你有帮助！

蓝牙技术是一种最基本的蓝牙无线短程通讯技术旨在取代电缆连接便携式和/或固定装置 同时保持高水平的安全. 蓝牙技术的主要特点是稳健、低功耗、低成本. 蓝牙规格统一界定为多种结构连接器、互相沟通. 蓝牙技术已经达到全球接受这种装置,使得任何蓝牙,几乎每一个国家, 可连接其它蓝牙装置,使靠近. 蓝牙使得电子装置连接和沟通,通过无线短程、AdHoc网络称为piconets. 每个器件可同时与多达七个其它装置在一微微网. 每个装置还可以同时属于多个piconets. piconets建立动态和自动装置,使进出蓝芽无线距离. 蓝芽无线技术实力是一个根本的能力,同时处理数据和语音传输两种. 这使用户享受各种创新解决诸如免提耳机语音通话 印刷及传真能力,同步的PDA、笔记本、手机应用等等. ●版本2.0版本规格核心+增强数据率(尼古丁损伤),通过11,2004u20221.2版,通过11 2003规格化妆跟其他无线标准、 蓝牙无线连接两种规格使生产商和应用层层定义 支持数据和语音应用. 蓝牙技术运转谱牌工业、科学和医学(主义)在2.4至2.485千兆赫频段, 利用扩频、跳频、全双工信号时象征率啤酒花1600/0.938 2.4千兆赫的ISM频段可在大多数国家和牌. 蓝牙技术干扰的自适应跳频(自适应跳频)的能力是为了减少干扰无线技术之间共享2.4吉赫 谱. 自适应跳频频谱工程利用现有的频率. 这是由在光谱检测等设备,避免它们所用频率. 自适应跳频这使得传输的频谱效率, 为用户提供更多的表现就算用其他技术随着蓝牙技术. 啤酒花之间的信号频率179兆赫回放给予高度干扰免疫力.

与现有的如ZigBee Mica Motes或者其它WSN相比，MyriaNed无线传感器网络在有些方面有所不同。首先，它是基于随机转发（gossiping，也可以不翻译）的。这是MyriaNed的主要的出发点与核心思想。这个思路是阿姆斯特丹自由大学（Free University of Amsterdam ）的Maarten van Steen教授提出的，现在则开始与Devlab合作研究。由于随机转发的自然特性，使得WSN在路由方面与经典方式与众不同。我们已经开发出了自己的MAC协议，称为gMac。这种MAC协议的基本特性是广播传输，这就意味着MAC层不需要一个ID或网络地址。然而，给网络中的每个节点分配ID是有一定必要性的。当然这个工作在MAC层之外，一般在应用层中完成。对于一个WSN的应用而言，能源效率也是非常重要的。由于无线通信是WSN节点中能源消耗最多的一部分，因此gMac的一个特别属性是解决这个问题。gMac使用一种在节点之间严格同步的TDMA协议进行信息通信。接下来的章节将对上述问题进行更为详细的描述。

不是,求采纳,,

角度和经纬度中，度分秒也使用60进制。六十进制是以60为基数的进位制。我们所习惯的印度-阿拉伯数字，就是一个以10为底的计数与演算系统。例如，在234中的2代表200，25中的2代表20，而102中的2就代表2。在一个完整的进制系统中，必须要有代表“零”的符号，才能将可能缺项的位数补零。我们直式加减乘除，就是建立在这样的位值系统上。至于不使用进制的系统，大概只有罗马数字还算为世人所熟悉。这也是一个以10为基底的系统，但它用I、X、C 、M表示1、10、100和1000，再加上V、L、D代表5、50及500作辅助。举例来说，1762=MDCCLXII。巴比伦使用的这个六十进位法是个不完整的进制系统，因为它缺乏代表“零”的符号。但它与我们系统是很接近的，它使用59个不同的符号代表1至59，当泥板上由左至右出现5、6、3时，它的意思是 =18363。这使得一个很庞大的数字变得容易纪录。巴比伦六十进位法如前所述，它一直没有“零”的符号，也没有小数点。虽然有时他们会将某一位空下来以代表缺项，但也因没有统一使用，让我们后人无法直接从数字符号上去确定它的值。此时我们只能从泥板的上下文去判断了。这样容易混淆的状况，一直到约公元前300年波斯人“发明”了“零”的符号，才大有改善，但小数点仍一直没有被使用。
