The Military-industrial Scientific Research System of the Academic Master Chapter 822

Chapter 822 Testing with an early warning aircraft

In the next half hour or so, Tang Lintian felt dizzy.

Floating.

The feet are off the ground.

Given the level of Mathematics major at Beijing Hang University, being able to invite a scholar of Perelman's level to give a report is already something worthy of celebration.

In the end, Chang Haonan turned around and gave him such a big job.

It's basically equivalent to a person worrying about having enough to eat one second, and then suddenly learning that he is the son of the world's richest man the next second.

This description is no exaggeration.

In the current situation, if Chang Haonan is willing, Tang Lintian probably won't care about trivial issues such as seniority...

In short, when the latter woke up again, he found himself in Chang Haonan's office.

I don't remember what happened in the middle at all.

“Professor Chang.”

When Tang Lintian was speaking, he still felt his heart beating very hard, so he slowed down a little in the middle of speaking:

"This result...about...when..."

As a man in his fifties, he has deeply felt the mark left by the passage of time on his body.

But at this moment, if there could be a fast-forward button in life, Tang Lintian would press it without hesitation.

I really can't wait…

Poincaré's conjecture…

Even if he is not a mathematics professor, he still knows this famous name.

It is as famous as Goldbach's conjecture and Fermat's last theorem, a problem that has troubled mathematicians around the world for more than a century (actually the Poincaré conjecture is of higher significance, but those two are really out of the circle).

If it is solved on Beijing Airlines...

Don't say anything else.

The lecture theater where the lecture meeting was held yesterday can be directly promoted to a sacred place of mathematics——

Don't ask, just ask. The inspiration for solving the Poincaré conjecture came from this place.

As the current principal of Jinghang University, Tang Lintian is definitely honored.

“It's hard to say.”

Chang Haonan shook his head and replied:

“In mathematics, the most time-consuming part is often not necessarily the most difficult part.”

He understands Tang Lintian's mood, but since the current theoretical level of LV3 is not enough to start the project, the Poincaré conjecture has not been solved directly through the system, so it is difficult to give a clear timetable.

All we can say is that in terms of supercomputing performance at the turn of the century, his own expectation was 3-4 months.

“Yes, also...”

Although he didn't hear the answer he wanted, Tang Lintian still nodded repeatedly:

“It will definitely not be simple to study a problem that has not been solved for a century...”

After this topic came to an end, the office fell into silence again.

Tang Lintian, who was still not overly excited, was still a little unable to sit still, but in front of Chang Haonan, he couldn't jump up and down to vent.

So after sitting uneasily for a few minutes, he finally lost his temper and stood up:

“I'll go find Professor Meng and talk about your project.”

Chang Haonan was just about to say that it was just a phone call, why bother making a special trip.

As a result, when I looked up, I saw Tang Lintian's back almost jumping out of the door...

"well…"

He sighed, put down the hand he was about to pick up the phone receiver, and shook his head with a smile.

About 40 minutes later, Tang Lintian, who seemed to have returned to normal, finally returned to Chang Haonan's office with Meng Zhenyuan.

And after hearing that Chang Haonan had found a solution to his problem, Meng Zhenyuan's reaction...

It's basically not much different from Tang Lintian just now.

This time, Chang Haonan, who had gained experience, did not disturb the two people opposite him, and just kept busy with the matter at hand.

Sure enough, after a while, Meng Zhenyuan finally came back to his senses.

"No, Mr. Chang, this...is it true?"

Chang Haonan was immediately amused:

"Of course."

He looked away from the computer screen and looked at the two people sitting on the sofa:

“Can I still lie to you?”

“No, no, no…of course I believe Professor Chang…”

Meng Zhenyuan rubbed his hands.

Obviously, although he has recovered from the initial shock, his language and thinking abilities have still suffered some impacts:

“Oh my God…”

Meng Zhenyuan sighed again, then looked at Chang Haonan and said sincerely:

“Mr. Chang, since you have solved this problem, do you think...are there any equipment or equipment that need to be purchased? I can use the funds from this project to help you solve it!”

This is indeed a minor trouble—

The project in Meng Zhenyuan's hands is a vertical project, and the management of funds is much stricter than that of horizontal projects.

At least it is impossible to be like the agreement signed by Chang Haonan and the China Petroleum Pipeline Bureau. If the project is completed ahead of schedule, the funds will be paid in one line at the end of the project in the name of personnel expense subsidies.

For vertical projects, if the funds you apply for are not used up, not only will you not get an award, you may even be rejected.

The logic is also very simple - why did you apply for so much if you can't spend it all?

But even so, when applying for a project, no one will really think about how to spend the money first, and then get the money according to the planned amount.

But we must get as much funding as possible and then find a place to spend it.

So, at the end of each year, and when the project is about to be completed, there will be a sudden expenditure of money——

Of course, this is definitely a happy trouble.

For most research groups, the trouble is not enough money, rather than not being able to spend it all...

However, the problems Meng Zhenyuan is facing now clearly exceed all past experiences.

It's not that he has some money left over and needs to be spent, but he's about to finish the question without spending even a penny.

“Hmm…how many?”

Chang Haonan was not polite, after all, he was the one who solved the problem.

“Three years, 200,000 per year.”

Meng Zhenyuan replied.

“That doesn't seem to be enough to do anything…”

Chang Haonan held his forehead with one hand.

In fact, a project with a funding of 600,000 yuan was definitely considered a big project in 2000.

It's just…

There is no harm without comparison.

Finally, he decided to skip the topic:

“Forget it, let's keep it for now. Anyway, the completion of the question will have to wait until the end of this year at the earliest. I will contact you when I have any money that needs to be spent.”

The issue of funding can only be regarded as a digression.

The focus is still on the project itself.

Next, Chang Haonan spent about two hours introducing his improved manifold learning algorithm to Meng Zhenyuan and Tang Lintian, as well as the idea of using this algorithm to extract and analyze multi-band spectral data.

To put it simply, in an era when sensors are highly developed, the problem people face is not too little data but too much data.

So much so that it's impossible to tell which ones are useful and which ones are useless.

Manifold learning technology can accurately extract the specific data needed for analysis from a radar imaging map filled with information in trillions or even gigabytes.

Of course, this is just one of many application scenarios.

If the computer performance is strong, advanced functions such as face recognition and image search can also be implemented.

“Sounds very...perfect.”

After Chang Haonan's introduction, Meng Zhenyuan felt that he was almost convinced by this exquisite method:

“However, there is still a problem...”

“Our satellite will not be launched for more than a month...Although I also think this idea is feasible, it still needs to be tested..."

In the final analysis, the former's movement was a bit too fast.

“Hmm… indeed.”

Chang Haonan nodded:

“It may take three months for the satellite to transmit the data back, and if the geological information needs to be verified, we have to wait for the results of on-site exploration to come out, which is really inefficient..."

He believed that the algorithm he developed would be correct.

However, in order to optimize a good enough effect, enough samples are still needed for comparison and parameter adjustment.

With one satellite, Ziyu-201, and dozens of people from the Exploration and Development Research Institute, it may be difficult to meet the efficiency requirements.

“Anyway, as long as it's telemetry data, how about letting the two Learjet Ss from the Academy of Sciences join in?”

Tang Lintian next to him suggested.

In the mid-1980s, China imported two Learjet S/II electronic reconnaissance aircraft from the United States, which were later named under the name of the Academy of Sciences.

In addition to military use, it will also perform some scientific surveying and mapping tasks.

Chang Haonan waved his hand:

“The shortcoming of this area is the inefficiency of on-site survey, even if there are two more aircraft..."

At this point, his eyes suddenly lit up.

At the end of the day, the function of the manifold learning algorithm is feature extraction.

Then you don't have to limit your attention to geological information.

Ground reconnaissance, battlefield surveillance, target identification…

It is also true.

And because targets such as buildings and vehicles are controllable, it can even save the effort of data verification.

At this moment, an excellent test platform suddenly flashed in his mind—

The Air Police 200 has already made its first flight.

Although the centimeter-wave radar has limited accuracy when detecting the ground and cannot be compared with serious synthetic aperture radar, considering the huge antenna area and power, if it is only used for technical verification, it should not be a big problem.

Moreover, it kills two birds with one stone.

In addition to verifying hyperspectral remote sensing equipment, we are also making technical preparations for China's future battlefield command aircraft, comprehensive reconnaissance aircraft, or strategic reconnaissance satellites!
