hey Hendrik... your automatic translations are pretty good, will you run it
?

anyway, the vid is cool:


I liked the terminal station (if this is the word here) most:

I am not much fan of Scify but here it is. It will cost a fortune to built this

Creating an ultra-fast Maglev high-speed train network, allowing passengers to travel from one Chinese metropolis to another in an hour, is the project announced by CASIC on Wednesday at the 3rd Aerospace Trade Summit Currently in Wuhan.

The Chinese national group, specializing in space launchers and missiles, plans to finalize the technological demonstration phase by 2023 on a "mini" experimental network linking three Chinese cities, with prototypes of up to 1,000 km / h .

If these initial commercial trials are successful, with an estimated volume of 8 million passengers per year, CASIC will then begin the second stage and go to challenge the 2,000 km / h bar by 2027, , The speed of 4,000 km / h, 5 times faster than an airliner, or 10 times a conventional TGV.

To be able to beat most fighter planes in speed but on the ground, engineers try to avoid any form of "physical contact" between the train and its environment during the "rolling". For this, some technical solutions chosen are identical to those of the Hyperloop project , launched in 2013 by the founder of SpaceX.

Each of the independent trains will circulate, like Hyperloop, in a vacuum tube, whose aerodynamic drag represents only 3% of a conventional TGV. This will also considerably reduce the aerodynamic heating of the structure.

The highly streamlined train - 35.8 meters long, 2.24 meters high and 2.12 meters wide - will also benefit from CASIC's long experience in the hypersonic field, acquired with the development Super and hypersonic missiles.

The propulsive part will use the concept of magnetic levitation train (Maglev), with superconducting magnets.

Electromagnetic forces are also used to lift the train up to 20 tons, carrying 18 passengers in the single wagon, about 20 mm from the "rails" to avoid mechanical friction, while Hyperloop simply floats on a "cushion" 'air.

It is unclear whether the main TGV manufacturer in China, the CRRC Corporation, which has also launched

, is participating in this project, which is almost a competitor to theirs. But CASIC, having virtually no experience in the development of railway assets, is already announcing the formation of an alliance with about 20 organizations, which holds more than 200 patents in the associated technical fields.

With this very ambitious project of which the amount of investment is not made public, CASIC wishes to diversify its activities which are mainly military oriented today.

It also wants to seize the opportunity in this new field because China considers the network of very high-speed trains, whatever the technology, as one of the main catalysts and facilitators to come for its socio-economic development. The Chinese group is also discussing the possibility of exporting or expanding the future network to countries that are part of the One Belt One Road strategy to make this Maglev vacuum train a future Chinese flagship in the international market after Aerospace, TGV and nuclear.

If this Chinese project materializes and reaches its ultimate goal in terms of speed, it will be possible to travel, for example, 1,152 km between Beijing and Wuhan in just 30 minutes, against 5 hours by TGV today. This new "proximity" will therefore profoundly change the way of life of the Chinese of tomorrow.

To be continued.

A more detailed read on Huawei's new chip ...
Huawei unveils faster phone chip it says can beat Apple, Samsung
Eric Auchard

BERLIN (Reuters) - Huawei aims to use artificial intelligence-powered features such as instant image recognition to take on rivals Samsung and Apple when it launches its new flagship phone next month, a top executive said on Saturday.

Richard Yu, chief executive of Huawei’s consumer business, on Saturday revealed a powerful new mobile phone chip Huawei is betting on for its upcoming flagship Mate 10 and other high-end phones to deliver faster processing and lower power consumption.

Huawei will launch the Mate 10 and its sister phone, the Mate 10 Pro, in Munich on Oct. 16, Yu confirmed. He declined to detail new features, but the phones are expected to boast large, 6-inch-plus full-screen displays, tech blogs predict.

Artificial intelligence (AI) built into its new chips can help make phones more personalized, or anticipate the actions and interests of their users, Yu said.

As examples, he said AI can enable real-time language translation, heed voice commands, or take advantage of augmented reality, which overlays text, sounds, graphics and video on real-world images phone users see in front of them.

Yu believes the new Kirin 970 chip’s speed and low power can translate into features that will give its phones an edge over the Apple iPhone 8 series, set to be unveiled on Sept. 12, and Samsung’s range of top-line phones announced this year. Huawei is the world’s No. 3 smartphone maker behind Samsung and Apple.

“Compared with Samsung and Apple, we have advantages,” Yu said in an interview during the annual IFA consumer electronics fair in Berlin. “Users are in for much faster (feature) performance, longer battery life and more compact design.”

The company asserts its newly announced Kirin 970 chip will preserve battery life on phones by up to 50 percent.

Huawei describes the new chip as the first Neural Processing Unit (NPU) for smartphones. It brings together classic computing, graphics, image and digital signal processing power that have typically required separate chips, taking up more space and slowing interaction between features within phones.

Most importantly, Huawei aims to use the Kirin chips to differentiate its phones from a vast sea of competitors, including Samsung, who overwhelming rely on rival Snapdragon chips from Qualcomm, the market leader in mobile chip design. Among major phone makers, only Apple and Huawei now rely on their own core processors.




The 970 is designed by Huawei’s HiSilicon chip design business and built using the most advanced 10 nanometer production lines of contract manufacturer TSMC.

China's super steel
Chinese scientists make breakthrough in super steel
(Xinhua) 08:51, August 25, 2017
Chinese scientists said Thursday they have developed a super steel that has a high level of both strength and ductility, a breakthrough that may have a wide variety of industrial applications.

Furthermore, its material cost is just one-fifth of that of the steel used in the current aerospace and defence applications, they reported in the U.S. journal Science.

Strength and ductility are desirable properties of metallic materials for wide-ranging applications, but increasing strength often leads to the decrease in ductility, which is known as the strength-ductility trade-off.

A Hong Kong-Beijing-Taiwan mechanical engineering team led by Huang Mingxin from the University of Hong Kong adopted a new manufacturing technique called deformed and partitioned (D&P) to addressed the problem.

"Steels have been the most widely used metallic materials in the history of mankind and can be produced with much higher efficiency than any other metallic materials," the team said in a statement.
"Therefore developing a strong and ductile breakthrough steel has been a long quest since the beginning of Iron Age in mankind history."

The team explained that it is very difficult to further improve the ductility of metallic materials when their yield strength is beyond two Gigapascal (GPa).

Now, they made "a successful attempt in realizing the above dream" as the newly developed method yields a "breakthrough steel" that has the "unprecedented" yield strength of 2.2 GPa and uniform elongation of 16 percent.

"The developed D&P steel demonstrated the best combination of yield strength and uniform elongation among all existing high-strength metallic materials," the researchers said.

"In particular, the uniform elongation of the developed D&P steel is much higher than that of metallic materials with yield strength beyond 2.0 GPa."

According to the team, the "breakthrough steel" belongs to the system of so-called medium manganese steel that contains 10 percent manganese, 0.47 percent carbon, 2.0 percent aluminium and 0.7 percent vanadium.

"No expensive alloying elements have been used exhaustively but just some common alloying compositions that can be widely seen in the commercialized steels," they said.

Another advantage is that this steel can be developed using conventional industrial processing routes, including warm rolling, cold rolling and annealing.

"This is different from the development of other metallic materials where the fabrication processes involve complex routes and special equipment, which are difficult to scale-up," said the team.

"Therefore, it is expected that the present breakthrough steel has a great potential for industrial mass production."

The research outcome was a collective contribution from scientists at the University of Hong Kong, University of Science and Technology Beijing, City University of Hong Kong, and a university in Taiwan.

Wupps :eek: ... sorry, but here's a new one ;)
Chinese firm provides computing services to Russia

2017-09-04 16:46

Xinhua Editor: Mo Hong'e

China's leading computing technology firm, Dawning Information Industry Co. Ltd. (Sugon), is exporting computing services to Russia with the launch of its overseas information service program.

Han Meijun, deputy manager of Sugon's overseas business section, said on Monday that under the "Seed Program," Sugon has provided high-performance computing services for Russian government organs and firms.

"Russian governments such as the municipal government of Moscow, the financial sector, including the Moscow Exchange and Finam, telecom operator Megafon, and aircraft maker Sukhoi have started cooperating with Sugon for high-performance computing services, information technology innovation and personnel training," said Han.

In addition to the service, Sugon has received an order from Megafon for computing hardware products.

Han said Sugon hopes to spread the computing service to Russia and other BRICS countries, as its applications can help advanced manufacturing and service markets.

Backed by the Chinese Academy of Sciences, Sugon is the developer of the supercomputer Nebulae or Dawning 6000, which ranked second on the TOP500 list of the world's most powerful supercomputers in 2010.

The company is also a major developer of the world's largest radio telescope in southwest China's Guizhou Province, which requires a strong computing system to support massive data storage and processing.

Han said Sugon has been promoting internationalization. It has been involved in a number of projects in data center construction, smart city building and information services in countries such as Slovenia, Laos and Ethiopia.

Google Continues to Hire in China Even as Search Remains Blocked

At least 20 positions based in Beijing are advertised on the company’s

, spanning engineering and marketing to product managers. Multiple listings are shown in the field of machine learning and artificial intelligence.

Some of the jobs were first flagged in May by Jia Li, Google’s head of machine learning and AI research and development, when the company hosted a summit on the field in the historic Chinese town of Wuzhen. There has long been speculation that Google wants to get its search engine back up in China, the biggest hole in its global dominance of web advertising.

Among the specific machine learning roles the company is seeking to fill are a software engineer, technical lead and research scientist, according to listings on the Mountain View, California-based company’s website.

The company is also seeking to hire workers in Shanghai and Guangzhou.

Google defied the Chinese government in 2010 when it said it would no longer self-censor content and redirected mainland users to an unfiltered Hong Kong site. Its search engine and most of the company’s other services, such as Gmail, were later blocked even as its Android grew to become the country’s most popular mobile software.

The company has been seeking to promote use of its TensorFlow AI tools in China.

Google isn’t the only U.S. company with services locked out in China, with Facebook Inc. and Twitter Inc. among those blocked on the mainland.

While its social network is banned, Facebook is said to have released a photo-sharing app called Colorful Balloons in May.

Remember how Google before it was kicked out of China treated its Chinese employees as if they spies and not letting them have access to Google's code like it does everywhere else in the world for fear of theft. I wonder how they're going to manage that paranoia since China-centric apps are big explosive business in China since Google wants back in.
