New concept of foldable giant wind blade designed for modular fan design

New concept of foldable giant wind blade designed for modular fan design

  United States a joint research team recently released a collapsible, modular fan design, applied in designing wind turbines can be used for bad weather conditions the self-protection function, can be used in large power generation on the sea fan wheel. The research team, from the University of Virginia Department of mechanical and aerospace engineering Professor Eric Loth, who led, including the University of Illinois, University of Colorado, Colorado Mining University, national renewable energy laboratory, and Sandia National Laboratories researchers.

  The design team is called "segment deformation of light wind wheel" (Segmented Ultralight Morphing Rotor,SUMR), downwind of the blade according to the installation in dangerous weather conditions can fold up like a palm leaf, this blade is able to realize the maximum leaf length and lightweight, segmented design lets blades installed in the field. When the folding blade reaches maximum length, in heavy seas, a strong wind blows can be issued under 50MW of power peaks. If using the traditional configuration, such a blade would be surprisingly heavy, but under the new segment structure design, long blade can reach ultra light structure weight.

  In the United States on the sea, usually has a huge wind turbines. But traditional fans with super long blade design will not be able to withstand the wind intensity is destroyed, the new design has to deal with inclement weather, Adaptive design in the wake of gale wind when it curves, can completely put away in the hurricane, will minimize the impact factor. Current scientific research team has received from the United States Department of energy's advanced research projects Agency (ARPA-e) 3.56 million dollars funded research teams will work to promote the commercial application of new design.

DuBike Baidu is not a car is a conceptual

DuBike: Baidu is not a car, is a conceptual

In 2014, Baidu, music video and other Internet companies have joined the army of bicycle, 700Bike, BiCi and Zebra bicycle start-ups have become this "movement" of beach-goers, and Internet companies to "subversion of the traditional bicycle" spoil moves a little blood.

Baidu DuBike debut in November last year, amid speculation that the DuBike should be at the end of 2014 or early 2015 at the latest to launch. But since since November last year, about DuBike silent, no DuBike of any new developments in this "quiet" cannot help but raises behind Lenovo: DuBike what's wrong? Vera Bradley wholesale

Baidu is not a car, is a conceptual

Baidu Baidu internal self balancing vehicles with DuBike is two parallel projects were originally two concept products, self balancing vehicles were in fact more likely to "own" car, similar to the drone; and DuBike is an operating system.

In General, the Baidu hardware logic is to first work out concepts, prototypes, and final production of products. DuBike this is an example of the projects from about April 2014, the senior level of the concept of DuBike is said to have originated from the original Baidu: "we should let China's return to the Kingdom of bicycles. 」

In order to implement it, Baidu cooperation with Tsinghua University Academy of hand, DuBike in the end prototype launched in October last year. This bike is "intelligent" is mainly reflected in Baidu's two core products: Baidu and Google map of the brain.

DuBike in the beginning of the project, Baidu's in-house resources are in place, both in terms of team-building or funding are fully supported. But after the Spring Festival this year, DuBike project began there were some problems: Baidu's attitude changes, support for DuBike as before, even when the application's budget has been cut in half.

This is why in the last two months, the outside world began speculating about the DuBike project "die."

DuBike exist in name only?

Look at Baidu to launch hardware products, we will find Baidu is not Google focus 10/10 future product development and more focus on products in the 1-3.

A person close to Baidu's internal network reporter told Lei feng, many hardware termination is based on Baidu's top consideration. The intelligent hardware category range, long hardware development cycle (typically between 8-15 months), you don't see immediate profits in the short term. In addition, if the product was not ready will also affect "Baidu" brand.

DuBike first prototype in November last year, Baidu MOMENTS marketing event on public appearances and are not marketed, DuBike team is trying to through continuous product iterations to further improve the DuBike of capabilities and experience, helping to attract more people to pay attention to DuBike.

But for a hardware product, the superposition of any of the new features in hardware costs and will spend money on the development cycle and time, it is clear that this is not the normal rhythm of the hardware. This also reflects the Baidu does not follow the hardware polished product of thinking, thinking like a normal hardware is listed, the first generation of products marketed through iterative product listing.

In addition, Baidu's internal evaluation system for the DuBike team going nowhere fast. Because Baidu internal evaluation mechanism is linked to the employee's immediate benefit, if DuBike only millions of profits a year or less, is a risk for the DuBike team, unless profit can reach tens of. And Baidu on the DuBike business model is not clear, this can also be seen as DuBike was eventually "killed" one of the reasons.

DuBike project budget at a later stage, without sustained investment, commercial appeal is not clear and an internal evaluation system lead to DuBike cannot be committed to the project team members, therefore basically determined in Baidu's internal DuBike this item actually exists in name only.

DuBike is still "alive"? Vera Bradley cell phone case

While the fate of DuBike to an abrupt end, but some areas still continue to operate: it's possible the continuation of life through a partnership with giant.

In the second half of last year, Baidu IDL and giant's leisure brands Mo Mandun (MOMENTUM) entered into a collaboration, through cross-border cooperation and launch carrying DuBike bike.

Baidu cooperation with giant are mainly Chinese and other brand and influence, including the advanced vehicle manufacturing process and control for details. And Baidu on the cooperation is mainly responsible for core parts: vehicle concepts, algorithms, and combined with Baidu's business.

In the course of cooperation, giant puts on one condition: DuBike this scheme must be made within 6 months before you can work with other manufacturers, in an effort to keep the giant in the industry's leading. DuBike portable to other brands may need to take one or two months time on the bike fit.

Vera Bradley cell phone case

Of course win like Baidu and giant, is supposed to be in the sales is not a problem, but because of low margins for bicycles, giant marketing costs are relatively high, so the bike the final price expected to be too low.

In addition, the DuBike in cooperation with the giant, almost no money to be made, while Baidu or follow the business model in the past: giant advertising on Baidu, Baidu's online advertising business for profit.

In order to give an explanation, DuBike still available

One of the senior people in the industry have said, Baidu internal concept of intelligent hardware products are focused on little ground, but there is no denying that Baidu is a giant BAT in the best effort of the hardware.

Recalling Baidu has launched the hardware products: Baidu easy mobile phone, shadow rods, small route, searched Baidu chopsticks, although eventually released, but mostly dismal sales, underwhelming. This reflects to some extent the Baidu does not understand the hardware, because the hardware products related to teaming, design, development, supply chain, budgeting, marketing, sales, after sales, such as a series of links, while Baidu's input in this area seem to be far from enough.

But at the current pace, Baidu and giant cross-border cooperation has come to end this bike probably will put on sale later this summer. Hope that this is not "after joy and left with a feather" scene.

Phone number behind the anonymous hedge

Cloud Conference in mid-July and a white hat (front of hackers, skills that can identify your computer or network vulnerabilities but are not malicious but informed as soon as possible and repair) armed with an Android Pad is called opposite him a cell phone, a couple of seconds after the phone's incoming call number display "18688888888". In fact, after just a half-hour set, cost tens of thousands of calls, this Pad can be "set aside" any number he wants. YSL iPhone 5 Case

This is arbitrary, if combined with personal information being leaked or on the black market to buy the network, use it (fraud) (cheating) will be more productive than the more common 400 win phone. White hat of cloud platforms cited an example: female college student missing, Crooks posing as her mobile phone to call family, perhaps cheated tens of thousands of minute transfer.

Phone number behind the anonymous hedge

Any call could be forged

Calling number changes there is no difficulty, the whole process cheats just a VoIP service provider, a tool to cheat mobile number, certification (part of the network the phone might read this number to display) as well as valid contact information can. This is the Internet and carrier network identifying blind spots that appear when network operators call the traditional operator agreement on calling number for identity verification.

Passer-by tells us that when we call on a traditional telephone network, calling and being called by operators connected at both ends, that is,

Calling of the = operator = operator = is called.

Operators at this time via mobile phone hardware and SIM card to transmit a unique identification ID, caller's identity could not be faked (unless you use operators to kill).

But after the rise of Internet telephony, it is no longer controlled by operators along the chain, VoIP operator or ISP involved. When Internet telephony users (such as a Pad) call, its chain is

Pad= VoIP operator =, operator = is called.

Network operators call the traditional operator in the process, it uses the Protocol itself does not have any identity verification, operators are considered to be fully trusted. To the Pad to give a fictitious ID, which trick the phone operators, can turn into an arbitrary calling number.

All VoIP service, tool to cheat mobile number, certification is not difficult to obtain, if not, developed from scratch don't require too much effort. YSL iPhone 5 Case

However, arbitrage, fake number just mobile first.

"Traffic is King" phishing sites

Phishing Web site traffic is the Internet a "taunt".

Assume 3 things top on the Priority List of phishing sites, is that these 3 things will flow, flow rate and flow. If in addition to the 4th thing, that is a reasonable one iteration.

Fishing website traffic sources has a wide variety of was (and still is), including IM, search engines, small site advertising, social networks, pop and some highly approximate address. But now many were blocked by security software, bulk SMS spam has become an important source of traffic, which is highly dependent on a fake base station.

Interpretation of pseudo-base station in Wikipedia is like this:

Generally by the host and portable computer through bulk SMS, SMS transmitter device to search and seize its Center, phone card information within a certain radius, through base station masquerading as operators, using other phone number forcibly sent to the user's handset fraud, advertising and other messages.

Larger initial pseudo-base station, only a GSM network for China Mobile and Unicom 2G; now by pressing 3G, 4G, signal upgrades, devices were also more compact, mostly car, and even placed in a backpack version.

YSL iPhone 5 Case

But beyond the generation, pseudo-base station works is like this:

Within the truncated access of mobile phone base stations normally communication = pseudo = SMS = base station released a successful of the phone.

Development of pseudo-base station is not difficult, so once the programme out of or sold in the market, individuals or small workshops can be produced. 13 years ago has a lot of direct traffic in machine site on the Web, these equipment are called bulk SMS Taobao, renamed the 900 and 1800 equipment after being banned.

Lei feng's network journalists free to change a few words in Baidu, and you'll find the two sellers.

First is a sales machine, assemble the second home is sold piecemeal.

Phone number behind the anonymous hedge Phone number behind the anonymous hedge

By such base stations after the traffic, fishing stations operational principle whereby those who are willing to take the bait, more precisely who is silly and who to.

Cloud man told us that domestic fishing station in the second half of the year increased significantly, in 5-peaked in June of this year; now the fishing stations produced more detailed, even very close to the real interaction logic. Many phishing sites in the past simply fill in some bank card information, many new sites will allow users to rapidly complete the transfer in the interaction design.

Domestic fishing stations there are more concentrated development upstream, most sites use the same set of back-end systems, in which passers-by are often called knife technology Studio. Although called the Studio, but probably only a small development team or even a person.

Clouds of white caps and even showed us a fishing station in which they scored the background, you can see the site online in less than 20 days has more than 360 pieces of bank card information includes name, card number, password, ID card, valid credit card CVV are substantially complete, but this was only a small "single site".

Mature fish team will buy multiple domain names pointing to the same site. Due to the back-end system is widely used, sometimes like sharp knives Studio Team even than the fishing operation is to make money. Security circles also have always had a joke: the difference between white hat and Black Hat is a monthly salary of 10,000 10,001 daily.

According to incomplete statistics, number of new phishing sites from 50 to 150 a day and count the number of victims may be thousands of people a day, these sites live cycle is not too long, a lot of not more than 3 days, and probably to servers abroad. Fishing chain, in addition to the sale of template and source code, and dedicated team is responsible for the distribution (for example drove a fake base station running around). Judging from the geographical distribution of victims, many pseudo-base stations often replace a city a day.

Whether pseudo-base station or a fishing station, their activities online and offline is very flexible, but usually organizations are small, mostly less than 10 close team.

Countless black card, therefore the finish of wool

If the forged numbers and phishing sites are stupid and rich individuals that pull the wool is silly and gold companies. In theory any open rewards can be collected, including, but not limited to coupons, sweepstakes, rewards.

On April 6 this year, suning, a full 100 minus 50 activities were explosions using a threshold of just over 0.1. That night a lot of technical night scalps, is rumored to have a brush 17,000 single.

Suning's losses may be 50 million-70 million.

Suning is after brushing part Sun

Previously uncovered, including Uber's car was painted single-event:

Industry slang, no single driver name "patient", and scalping people known as "nurse". When issuing scalping requests, is to brush a single staff for "needle".

Scalping was immediately with a new user account, select the driver near the starting position, driver "orders" (actually empty) acquired after concluding the visit + Uber fare subsidies, then fare back to the scalp through other personnel, drivers leave subsidies, and scalping due rewards earnings once a fare of 30 Yuan for the new user.

Phone number behind the anonymous hedge

Uber starting pointers like "prick"

More than two procedures, we need some automated tools, bulk registration and most of the time need unused mobile phone number in order to register a new user, which spoke of a black card.

These black card appears as a platform for SMS receiving online, most with full multi-platform client (iOS, Android, Win etc), more important is that most of them have provided the Automation API.

Phone number behind the anonymous hedge

Automation API is the highlight

Phone number behind the anonymous hedge

Small cat pool

Passer-by tells us that domestic 5-6 large messages about receiving platform, each nearly 200,000 number, or at least millions of black card. These black cards through something called "cat pool" of special equipment receive information, of course, these black cards if a region will produce local base stations in the region to a halt, so they are actually "distributed"--more accurately is scattered everywhere in every number of the hundreds of scattered in different locations. According to the cloud track, these black card where the majority were concentrated in Guangzhou, Shenzhen and Dongguan in 3 places.

Another problem is worthy of study, millions can normally send and receive text messages, but no black card is where real-name identities come from? Insiders inform us two sources:

A is some outflow of industry message card, they had used to control the device networking only, so it is usually opened only traffic and SMS;

There is from the agents, agents rushed business number may be sold to these platforms, agents themselves have a lot of real ID information, and can even give their card to do the real-name authentication.

Then there is the black card, and some cats pools (CAT pool production is certified, but due to the large market such as TB, its purchase and use is difficult to monitor), so have the unlimited text messaging platform, there is no unlimited ID.

Therefore the present a professional sheep population is relatively fixed, there is a clear division of labour, like all project personnel specifically found, developers follow up quickly automate message platform to receive the verification code, and some even specialize in the recovery and distribution of coupons. Of course, compared to coupons, these people prefer cash and in-kind (for example iPhone sweepstakes, or financial sites to experience such as gold).

Insiders tell us that black card in the strict sense and therefore the wool is not illegal, but there is no clear gray areas. In fact, these SMS receiving platform has an API interface, Lei feng's network reporter without even thinking about what "normal uses".

General for, as long as has VoIP of exists forged number hard blocking; fishing station are only can track to of is they online Shang of front desk, these front desk also frequently replaced, and track line Xia of pseudo base station need quite density and number of personnel input, almost not too may; while wool of roots in stream of black card, but if no operators shots, also rarely was can hit these unlimited ID of source.

Instability of the Sun Starburst Galaxy in the universe

  As we all know, every day the Sun gives us light and heat, is a relatively stable star. Say it is stable, because over the course of billions of hours within the sun itself has been in a stable state, and no mass explosion or internal movement violently. It was thanks to this, life on Earth will gradually appear.

  Recently, the United States Space Agency (NASA) and the European Space Agency (ESA) jointly announced they captured images of a starburst Galaxy M94. The way that galaxies form stars, and our own Milky Way is different. Moschino Note 3 Case

Instability of the

  In General, ordinary galaxies such as the milky way, also can form stars, formed, however the speed is very slow, it will be a slow and steady process. In other galaxies in the universe, however, also commonly known as Starburst Galaxies, their star-forming process is very fast. Of course, Starburst Galaxies star formation process is very intense. Often by huge amounts of hydrogen atoms together, in special circumstances form a nuclear fusion reactor, a universe of "small explosions" to quickly form stars.

Instability of the

  In a sense, Starburst Galaxies formed and perhaps somewhat similar to the birth of the universe, perhaps from this perspective, the galaxies in the known universe this big Starburst Galaxies only a speck of dust. And our universe, perhaps even a bacteria is not. Moschino Note 3 Case

Instability of the

  In addition to the M94, M82 Galaxy about 12 million light-years away from Earth, and is also known as a starburst Galaxy. I have to say, standing in our perspective to appreciate Starburst Galaxies, is indeed very beautiful and fantastic.

Video games red and black hot money never losing the spoiler under

Is like a spring Gale, come up in the night, thousands of trees or pear trees in bloom. This quatrain is probably China's best portrayal of the current mood of the video game industry. Almost a night, and game video associated of venture project of valuation are turned with somersault rub rub rub to rose: a, project half Qian to China cattle fork hand tour media of hat out financing no ignored, return video Raiders of really instead put himself of valuation report voted Hou 100 million dollars; b project a years Qian valuation is 40 million dollars of voted Hou, now has is 120 million dollars, also is voted Qian, a years within valuation turned has near 4 times times, is because its catch game video of this spring.

Let these items skyrocketed within a year on is Saif in a video to make money like Sequoia and King bought the whole track owners, they roared, by Twitch's success to a great extent in the former.

Twitch is, all under Google, three years ago, Twitch is a subproject under the Just.tv and has now become a YouTube star venture project had to spend $ 1 billion to buy.

Who are know, Twitch in China actually acclimatized, although YY live monthly tens of millions of of water proved in China subscription playing tours of mode is line have pass of, but has two problem is Twitch of China disciples are must face of, a is expensive of bandwidth costs (Twitch in United States is can himself built IDC of, in Celestial this which foreign are make indefinite, because information security and industry control), II is China competitive game of atmosphere formed also go.

Video games red and black: hot money, never losing the spoiler under

But under the hot money, never losing the spoiler. OtterBox

First kill came in was rich with a-share listed companies background players: betta and flag. Alfy after the stop Hu from the b station a stop, to a standing position, do the fighting fish. Zhejiang media took the winger before winger directly battle flag.

Because it is backing a-share listed companies, therefore, betta and banners, two live player is a better than a big, two manufacturers to get jaw-dropping money, major money is also its weakest two points: one is to throw money on the bandwidth, the second is throwing money on the team. Bandwidth, a rough estimate is that two years is the investment of millions every quarter. On the team, two are constant arms race, has reached 3 million signing of the top-level teams every year, in addition, for some fans a number of players in the fighting fish flag, fighting fish flag into mechanism, in other words, this investment is tens of quarterly expenses.

But even with alpha support, betta now outside financing, burn like this who can't take it anymore.

In March this year, Twitch began to enter the tour started outside of the live video sharing, live so big is that putting wood in this area as well as broad market demand coupled with a case of the League of friends of Talkdata before, Flock, no less. This love is the most powerful, ShareSDK, travel shows and hand in mobile end users the largest media super fun to enter this field.

Broadcast operations, field need to accumulate more hand video sharing SDK requires potential energy at the channel port, need to be influential on the CP side, need offline have greater outreach capacity, needs to have power. But at the same time, hand video sharing SDK also requires an investment. Think about it, when you share recorded video you just can't share the YouTube platform, youku is to audit, an audit delayed the entire user experience is all wood, and have their own server, and all things entering the server link is expensive. Hand travel video sharing SDK this thing to do there we must face is the product itself, not too big, the user experience should be in place, for now, has released the SDK product volume is too large, these huge improvements in the user experience space.

This is enough to understand why love can get almost 1 time times higher than bettas valuations. Zuo Lin right Fox understands that because hand video sharing the things to be operating, the ability to take input and technology product end, Trinity than light throwing money at things more difficult, and more barriers.

Live and the SDK, a third school is content. Typical dust storm is a game set out ImbaTV,ImbaTV out what is not, a team valued at $ 20 million, but even so, Rob, innovation works thrown into a $ 4 million, Sequoia with a $ 2 million, it relates to the waves, strong BBC, demons and others relating to the appeal, but also because in a draught. Another genre is genre of video guide, 1006TV, super fun game media into this field, 17173 video in this market continues to splash on the game media, tour video is contested, theoretically at least one professional tour media does stand out, after all the media rely on the content for a living.

There is also a school service, is about video game and hand the competitive water bearers of this big market, not many players involved in this genre, but it is an area of grass-root entrepreneurs are most likely to find the opportunity.

Zuo Lin right Beaver optimistic about the following market segments:

1: hand Sports anchor brokerage. Around two or three lines of the wood have also entered the professional, but a professional candidate of potential players for brokerage business and talent service companies, the game host version can be understood as the company, after all, not every anchor can be as independent as the waves of the game portal, brokerage services around them, still have business to do.

2: a populist hand line the game. William Wei song WECG in the teacher always walk tall on international routes, has a chance. But even worse is the common events, such as cooperation with the CP open athletic clothing, like super fun Masters Series match.

OtterBox Note 4 Cases

3: hand the athletics community. Hand sporting media certainly has, but not as competitive community of hand odds the same bundle games, must have the professional semi-professional players playing together, quiet way.

Allow the neighborhood asking wood sets share sent + content + services players with it, really, uncle Zuo Lin is also participating in this sort of thing. As to why not to touch live, ahem, money more than silly come Uncle never touched, it's about a man bottom line, character pieces, but the bottom line centimeters taller than people. Under advertising, neighborhood if members also think that there are opportunities in this area and would like to get involved, you can contact Uncle Zuo Lin (app linjun1024), we can talk. OtterBox Note 4 Cases

Must pessimistic remind is that appears to be busy in this market, there are two big players end up once, may be decisive for the whole market: a live YY if imitation 100.COM split individually, the other is a QT, Tencent if modelled on Jingdong manipulation package to any of the players on the field will result in oligopoly.

Bubbles, surrounded by giant worth mentioning, the entire game video and competitive market in China after struggling for so long and finally like a wild lily has its own spring. Zuo Lin right Beaver trying to say is, compared to those who may be compared to the $ 1 billion the company's dream, together make a China tour started competitive can be rapid and orderly development of the soft environment is more precious, more exciting, more when we get old to have enough courage to look back at our bleak life in the past.

Lonely valleys, wild lily also has the spring. Video game in the Valley, tour spring sports.
