China Economy: News & Discussion

A self driving vehicle has to make a decision in 10ms and react within 50ms.

an 8MP camera produces 8 million pixels per frame at 30 frames a second. Each pixel is 3 bytes for RGB. 3 bytes times 8 million pixels is 24 million bytes or 24mb per frame. There are 30 frames per second, 24mb * 30 = 960megabytes per second or 8 gigabits per second. That is 1 camera, a car will have 12. Now each stage of the pipeline has to take the incoming data and put it through a model. Each model has a 10-20ms processing time. This latency is allocated to perception not sensor fusion. Sensor fusion uses more primitive matrix multiplications using predefined transformations. So in summary not AI while driving but during the calibration stage

 

[srevster]

also the calibration stage is not done using the onboard car computer. It is done hsing what is called sensor playback. The car records its sensor data with the device configuration and then it uploads it to the garage edge data center. The garage edge data center replays that sensor data “sensor playback” and the data center uses cloud GPUs to calibrate the boresighting parameters.

Regarding perception, the perception stack has lots of problems and the car constantly disengages. The cruise car needed intervention every 4 miles. There are hundreds of people providing remote assistance when the car gets stuck by manually operating it or telling it what to do.

Cruise confirms robotaxis rely on human assistance every four to five miles

Cruise recently took the drastic move of grounding all of its driverless operations following a collision that injured a pedestrian in San Francisco.

Sure doesn’t sound like an AI car to me.

the closest thing to an AI car is Tesla with its end to end neural network and real time maps, but that is a level 2 system.

you still haven’t answered the basic question I asked, how is either system better than having a human chauffeur.

in the self driving case, I would be georestricted and in the ADAS case I need to baby the system. In either case the user experience for that is poor compared to hiring a chauffeur who can take me anywhere anytime in any situation.

A very offhand question, just putting it out there. During that whole cold war era, how did the Latin American countries articulate their anti-totalitarianism? Did they have a deep, spiritual opposition to the whole concept of totalitarianism, or were they merely American client states, dominated by the US economically. The US deep state and a fairly large portion of the population do not seem to be moved or impressed by such expressions. What they( that type) care about is "Hey, do they buy weapons from us, and do our companies have a huge presence in their economies, including controlling most of their mineral wealth. And do they keep the Russians out" If you think about it, having a spiritual, philosophical opposition to communism and totalitarianism, would almost invariably have as a corollary, a deep opposition to imperialism and domination/hegemony by certain countries.

well to understand what happened to us you have to see severl factors, first most latin american nations have small populations, even today Colombia barely pass 50 million or Argentina is 44 million, in 2023 while the USA is 330 million.

Only Brazil or Mexico are in the range of 130 Mexico or 200 Brazil, most latin american nations are iun range of 15-25 million.

Add the fact the USA was and is the most industrialized nation in terms of inventions and scientific knowledge.

This made the USA unstoppable, in terms of technology and military might.

Add that Latin America has large populations of Europeans 37% of our populations are European descendants and 42% half European, this made us allies of the USA.

High-speed trains at 600 kilometers per hour are still under development,

Take it easy

Germany passed the technology

 

[MiG-29SMT]

If it's 450 kph which certainly seems the case , it's not MAGLEV but super high speed . Besides if I wanted to experience 450 kph speeds why would I travel to China ? I'd rather travel & experience it in the country of its origin - Japan.

The Maglev project seems like a great sucess but the reason few countries have it is simple.

It can not travel on the sea (airplanes can fly above water)
It is very expensive and ony for short distances
Difficult to adapt to current rail network

So at the end it is more practical have buses or airplanes

E-195 flies faster than Maglev, it is cheaper, more adaptable can fly above the sea and does not need a rail

The Maglev as avanced it is has a very expensve ticket price.

Electric buses are a better option since they are cheaper too.

Yes we do not have Maglev in Mexico or India but who needs it? in reality China will not be able to compete with airplanes with Maglev for a reason Germany has not a line and the japanese line is for a very short distance and still TGV s almost as fast as Maglev and airbus A-320 more practical

The current world speed record for a commercial train on steel wheels is held by the French TGV at 574.8 km/h (357.2 mph), achieved on 3 April 2007 on the new LGV Est.Dec 12, 2

Welcome aboard China's high-speed rail,

You'll find the answer

Currently, China only has one maglev line in commercial use, connecting Shanghai's Pudong Airport with the Longyang Road station in the city. The 30 km (19 miles) journey takes about seven and a half minutes, with the train hitting speeds of 430 kph (267 mph).

China successfully tests ultra-high-speed maglev trains that ‘fly on the ground’ - Global Times

www.globaltimes.cn

4,700 nautical miles

Along with an optional additional centre tank, it extends the A321XLR's maximum range to 4,700 nautical miles or 11 hours of flying time.

Do you understand what is a lobby?

Obviously most nations still fly aircraft and most nations do not have have speed trains.

Has Poland banned aircraft?

Italy?

USA?

Your whole argument shows you never thought why Maglev is not used in most nations, is it because China or Japan have a super high IQ?

The answer is economic reasons.

You will not tell me about high speed trains I have used TGV in France and I know the Shinkansen in Japan, the high speed train ticket is more expensive than aircraft tickets and it does not cover whole of Japan.

Now you think TGV has the range of regional jets?

Simply put it, A-220 allows you to get from France to India but TGV can not do that.

Chinese Maglev with 30 km range is it economical?

E-195 allows you to go from Paris to Moscow, Iceland or Morocco but TGV does not.

Stop dreaming, Germany knew Maglev is too impractical so they sold you the technology.

Train services are useful but you do not need super fast trains because the longer the rail network the most expensive it gets and in Mexico where you have jungle maintainance is very expensive, so you are dreaming MAGLEV is a VERY IMPRACTICAL mass transportation system yet.

Only for very short distances makes sense

another factor you have not seen is The Shanghai Maglev has different track systems, in Mexico for example we have an old track system, we have Jungle and we are a pretty big country, so it is impractical to get a super duper expensive Maglev from China that only has 30km of range, so we got a more convencional train from Spain for our old system of Tracks

Chinese subways systems have more practicality

This subway train was purchased from China and partially built in Mexico, some very limited tech transfer went on but China could sell some trains for the Line 1 of the Mexico city system.

The world's largest ethanol production unit started trial production to help food security and energy security-Chinanews.com video
2023/12/28 17:13:18

Highlights: On December 12, the world's largest ethanol production unit was set up in China. The facility will produce 28,000 tons of ethanol per year. The process is based on the use of dimethyl ether (DME) which is a form of carbon dioxide. DME is used to make ethanol from water, which is then converted into carbon dioxide by the process of hydrolysis. The use of DME in the production of ethanol has been approved by the World Health Organisation (WHO) and the Chinese government.





On December 12, the world's largest ethanol production unit, the 28,60 tons/year ethanol production unit, started trial production in Huaibei, Anhui Province, producing qualified anhydrous ethanol, which will help ensure food security and energy security.
The team of academician Liu Zhongmin of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences provided the key core technical support for the project of "syngas as raw material through dimethyl ether carbonylation and methyl acetate hydrogenation to synhydrous ethanol" (process name "DMTE"), the main raw material for the production of methanol comes from coke oven gas and is further converted into ethanol, which not only greatly improves the added value, but also provides a feasible way for the low-carbon integration and development of the steel and petrochemical industries.

On the same day, the trial production of 60,<> tons/year ethanol production unit was launched, relying on the independent technology jointly developed by Dalian Institute of Chemical Physics of the Chinese Academy of Sciences and Yanchang Petroleum Group Corporation, and was built by Huaibei Mining Group Carbon Xin Technology Co., Ltd. It not only verifies the advancement and reliability of DMTE technology, but also actively promotes the large-scale application of DMTE technology. In particular, this technology uses steel mill gas as a raw material to produce ethanol, which will promote the low-carbon integration and development of steel, energy, environment and other industries.
Up to now, DMTE technology has signed 13 sets of industrial plants (including 2 sets of export) technology implementation license contracts, ethanol production capacity of 395.<> million tons/year, with the successive commissioning of units, a new ethanol strategic industry is rapidly emerging.
The Dalian Institute of Chemical Physics, Chinese Academy of Sciences provided a set of videos to the media to introduce the research and development of DMTE technology and its industrial application.

Sorry nobody cares about how Mexico works, this is China thread and Mexico is not important in global economy.

For major economic entitiies, regional jet not popular.

China: 500-1200km, here are HSR, and longer we use 737, A320, C919
Japan: same as China
EU: 500-1200km, here are HSR, and longer they use 737, A320
USA: most important flights are between Eastern and Western coastal lines, they use 737, A320.

Are you a dickwad?

AI is not used to preprocess data for sensor fusion. It might be used in the machine shop to calibrate the sensors before the car hits the road. Do you understand basic concepts such as latency and reaction time?

sensor fusion is not something you leave to AI in a real time environment when the hit rate isn’t 100%. Most AI algorithms have a 97-98% recall rate. Sensor fusion uses something called auto calibration when the car is in the garage before it hits the road. This has no relevance when the car is actually driving because it will use the boresighting parameters which consists of both the translation unit vectors, the quaternion rotations, the intrinsics which define FoV and distortion.

Regarding India, where do you think the world’s HD maps are being created?

regarding India in AI.

Nah retard
U are just rotating the things to just win the argument having no idea where the hell u are going

Anyways I have to entertain a retard now
Data preprocess will require AI implementation in future for higher efficacy of self driving vehicles
AI algorithms can identify missing or null values in datasets and employ strategies like imputation
AI techniques, such as filtering algorithms or outlier detection models, help identify and remove noisy data points that could skew analysis results or machine learning models
Feature engineering require AI algorithms while using techniques like dimensionality reduction or encoding categorical variables
AI utilizes natural language processing (NLP) or computer vision techniques to preprocess and extract relevant information for analysis that is text and image processing
Most importantly data augmentation
Sensor fusion will definitely require AI to be more efficient in future thus increasing its practicality in self driven cars

How the f**k u can compare elxsi with Chinese self driven cars
They literally running and testing those self driving cars where as we barely have concept regarding it

L3 self-driving vehicle tests hot up in China

More automakers are being allowed to test Level 3 vehicles in China, a sign of mass adoption of highly autonomous driving technologies in the world's largest vehicle market.

That's the present day problem retard
Such things require AI algorithms to be efficient in future
For that u need to work and research in that direction which is being done extensively by West and China
Until Tesla doesn't run completely autonomously it will remain level 2
But u really require brain to comprehend
