Not only that, Changlian's AI portrait recognition and facial intelligence optimization algorithms can improve the subject brightness in low light conditions.

In terms of multi-screen collaboration, the mobile phone and the PC establish a connection by means of "one-touch" or scanning a two-dimensional code. The screen, mouse and keyboard of the PC become a shared resource. Not only can you know the mobile phone information and prompts in real time through the computer screen, but you can also drag and drop the pictures, videos, documents, etc. in the mobile phone to the PC for editing with the mouse and keyboard. After completion, drag it into the mobile phone window to share with WeChat, so as to realize data intercommunication and collaborative office experience.

In addition, Huawei can also connect with speakers, smart screens and cars through a touch. It is reported that Huawei HiCar realizes the interconnection of mobile phones and car machines, and the car becomes a large mobile phone with wheels, which not only can easily realize the application in the mobile phone screen, but also realize the use of mobile phones for vehicle air conditioners, door locks, speakers, etc. Remote control.

At present, Huawei HiCar has supported more than 120 models of more than 30 depots (including front and rear).

In addition, WMUI10 has a new design for icons, interface details, and colors, the addition of Morandi and the AI ​​magazine layout.

In addition to the UX design changes, EMUI10 also adds a lot of interaction mode, AI space control, users only need to swing the palms or do the grabbing action in front of the screen, you can achieve the screen scrolling or screen capture; EMUI10 AI turn around Based on the AI ​​attitude sensing, the face orientation is intelligently recognized, and the screen steering is automatically determined according to the face orientation.

Huawei Mate30 Pro is the first mobile phone to use the side screen virtual buttons. The volume can be controlled by sliding the left and right sides of the phone, whether it is left or right.

In terms of security level, EMUI10 adds AI information protection function, which can automatically identify the owner through the combination of face recognition and application lock. EMUI10 stores biometric information and passwords in a hardware-isolated TEE microkernel and performs operations within the TEE microkernel to secure information. In addition, the TEE microkernel has the highest level of CC EAL5+ certification for commercial OS cores.

At the same time as EMUI10's own technological innovation, Huawei also cooperated with Baidu Input, Cherry, Dajiang and other ecological partners to further enhance the full scene experience for users.

On September 26th, at the Yunqi Conference, Alibaba Cloud officially released the third-generation self-developed Shenlong architecture, fully supporting ECS ​​virtual machines, bare metal, cloud native containers, etc., running through the entire IaaS computing platform, and in terms of IOPS, PPS, etc. With up to 5x performance, users can get 100% of the computing power of a physical machine on the cloud.

Virtualization brings about a revolution in cloud computing. Its greatest value is to bring flexibility to computing, but at the same time it brings the burden of performance loss, but if the virtualization loss is not solved, the cloud computing industry will soon I encountered a technical ceiling.

After three stages of software virtualization, general hardware virtualization, and dedicated hardware chip virtualization, the third-generation Shenlong architecture realizes the unified architecture of bare metal servers, ECS virtual machines and other computing platforms, and users can obtain high-quality flexible resources. .

In addition, Alibaba Cloud also released a sixth-generation ECS example based on the Shenlong architecture, with a 20% increase in computing performance, a 30% reduction in memory latency, and a 70% reduction in ESSD latency. In addition, the highest price reduction for each product based on the new architecture is over 58%.

The Alibaba Cloud Dragon Architecture is highly adaptable to products such as containers under the cloud. Accelerated by I/O offload chip, efficient scheduling and automated flexible telescopic containerized products help users reduce computing costs by 50%, and performance is superior to physical machines.

Alibaba Cloud's millions of servers around the world will be fully upgraded to the third generation Shenlong architecture. Jiang Jiangwei, general manager of Alibaba Cloud Intelligent Basic Products Division, revealed that within Alibaba, the Shenlong architecture has been widely used in Taobao, Tmall, and rookie businesses to solve high-peak performance bottlenecks.

Xinhua News Agency, New Delhi, September 20 - Indian researchers have recently invented an environmentally friendly method of plastic degradation. They only need to place the plastic in a 70 ° C solution containing glucose and metal ions and continuously stir for several days to degrade the plastic into molecule.

A team led by researchers at the Indian Institute of Technology in Madras found that the new method can be used to degrade plastic materials such as Teflon. Related research papers have been published in the Journal of the American Chemical Society, Sustainable Chemistry and Engineering.

Polytetrafluoroethylene is a high performance material with heat resistance, chemical inertness, insulation stability and low friction. The researchers first placed a Teflon-coated magnetic stirrer in a 70 ° C solution for 15 days with metal ions and 1000 ppm glucose (1 ppm in parts per million).

The researchers then found tiny fragments of bright red glow on the surface of the solution. As a result, these bright tiny particles contained molecular fragments of a polytetrafluoroethylene polymer.

The study also found that Teflon did not show this degradation in the absence of agitation, glucose or metal ions; at room temperature, the degradation rate decreased; as the glucose content in the solution increased, the degradation of polytetrafluoroethylene The effect will be enhanced.

The researchers explained that PTFE may be electrically degraded into molecules by triboelectric stirring. They cautioned that because many modern cookware are coated with Teflon, similar chemical reactions can also occur on cookware, resulting in microplastics in food. Similarly, this triboelectric degradation process can also occur in the ocean, where there are a large number of metal ions, and the waves provide continuous agitation, which may be one of the ways in which marine microplastics are produced.

Huawei EMUI officially issued an article saying that the Ark compiler is ready for open source, "August 31 show you the code!"

On April 11 this year, Huawei's consumer business CEO Yu Chengdong announced that Huawei officially released the Huawei Ark compiler. This compiler can improve the compilation efficiency of Android applications, from the original interpretation and execution to the full-process machine code efficient running program.

Huawei's Ark compiler as a new Android application compiler can significantly improve the speed of mobile phones. According to Huawei's official data, the Ark compiler can improve system fluency by 24%, improve system response by 44%, and improve 60% of the three-party application operation fluency.

 
According to Huawei's official introduction, the Ark compiler is the first static compiler to completely replace the language virtual machine, and does not require an interpreter at all. A compiler that takes into account Java development efficiency and C language runtime efficiency. Compared to the existing compilation mechanism:

1. The Ark compiler is a static compilation method. In the existing Android system, running an application first starts the virtual machine, then reads the application code and interprets the execution one by one. It will occupy more processing resources and affect the efficiency of program execution. Of course, there are also early or runtime compilation techniques, such as AOT or JIT, that convert some of the programs into machine code and execute them directly on the CPU. However, it is still not possible to do 100% to get rid of virtual machine execution, which is the key to the current Android camp is not as good as the IOS camp.
2. The static compilation mode of Huawei Ark compiler can directly translate the dynamic features in the language into machine code. After the application is installed, the mobile phone can run the program at full speed, completely eliminating the drawbacks of the virtual machine and bringing about great improvement in efficiency.

 
3, the Ark compiler is a compiler deployed in the development environment, and the existing compilation process, mainly occurs on the mobile phone, bringing additional resource consumption.
