Hammer of Technology

If he finished his academic kitty and was still unsatisfied, Kong Wenjue would be able to push his own waffle over without having to order another one.

Of course, this is just an idea in Chen Diancheng's mind. After all, he came here with a purpose. From the moment they met, this top student in the Ning class, the well-known president of the Ning Society, began to do various psychological profiles of the opponent in front of him. Trying to find out what kind of person this is.

After all, Chen Diancheng, a living spy, had never seen one before.

"Thank you, Senior Brother Kong. This way, Senior Brother Kong's time will not be wasted. Let's get to the point. I just learned that I went out for an exchange last year, so maybe there are some things in the Ning Society that are not clear. That's it. Because the Ning Society has developed fairly well in recent years, and the number of club members has increased, especially at our Yanbei University, competitions, scientific research, etc. Everyone has signed up enthusiastically."

"And you know, our projects were very successful before. Although everyone said that they didn't do it for money, but these products have really made money, so we should give you some rewards. In terms of amount, it's not too small. , You also participated in the random algorithm event project before, although you are not a core R&D staff, you should have received more than [-] rewards, right?"

Kong Wenjue nodded slightly and said, "Well, the total is 16 yuan, 2 yuan in subsidies and 10 yuan in bonuses. I was surprised to receive this money abroad."

Chen Diancheng smiled, and continued: "That's right, although the reward of more than [-] yuan is not a lot, it is still very interesting to be able to do what you like, and to reward many students with cash. The current situation is that Ning Everyone is more and more enthusiastic about participating in the project of the club. It is the same situation that I did not see your application letter for the first time. There are too many applications received in the background, and it is easy to miss them. Can you Do you understand?"

Kong Wenjue nodded and said confidently: "Of course I can understand this, but Mr. Chen, there are still a lot of undergraduates in the Ning Society. To be honest, although the Ning Class is very strong, most of the undergraduates have not really been exposed to scientific research. field, experience in all aspects is still too little, especially in terms of linkage and running-in, it is still far behind graduate students. To tell you the truth, I have seen a lot of world this time when I went abroad, and I have gained more in-depth knowledge of many technical issues. I understand, especially the crystal shoe project, which actually has high requirements for wireless communication, which happens to be my professional strength, so President Chen must consider it."

Chen Diancheng smiled brighter, and replied: "That's for sure. If I hadn't looked at Senior Brother Kong differently, I wouldn't have specially invited you here to talk, right? Undergraduate students must be inferior to graduate students in all aspects. But others You don’t necessarily think so, as you know, there are so many vice presidents and project leaders in the club, most of them are undergraduates.”

"So, now the association is preparing to launch a selection plan, which will be implemented soon. If you want to enter a popular project like crystal shoes, you must first be assessed. All members who have submitted applications have the opportunity to be assessed. And for this assessment, our director Ning Everyone will pay attention, it’s a very good opportunity, how about it? Is Senior Brother Kong interested?”

After hearing this, Kong Wenjue really showed interest, and subconsciously asked, "Director Ning will also participate in Ning Society's assessment?"

Chen Diancheng immediately said: "That's for sure, you are also an old man who has participated in the project, and you should know that our project can be successful. Director Ning has helped a lot, and often gives some guidance."

"Ahem... um, um, yes!" Kong Wenjue replied with some embarrassment.

In fact, he really doesn't know this. Although he did join a key project before, he was only doing some peripheral things in that project and did not belong to the core team. Naturally, he didn't know what role the core team had in promoting algorithms and codes. Without Ning Wei's guidance, naturally he could only listen to Chen Diancheng's fooling around.

"So, this is the situation now. If Brother Kong is willing to participate in the assessment, I will send you the questions first. The questions of this assessment seem to be about the tools of mathematical modeling. It seems that Director Ning means to do A time series forecasting tool is probably a prophet model or the like, and the specific requirements are probably that it conforms to the design specifications of similar products and has certain innovations, and I have to go back and ask Director Ning carefully to find out, how is it?"

These words made Kong Wenjue dumbfounded.

This is really a bit - against the sky!

Does Ning Wei have a correct understanding of Ning She and these brats?Let these people do the prophet model for assessment?

This technology is nothing new, it is nothing more than the process of predicting time series data based on additional models.Good prophets can be used in many applications to generate reliable planning and goal-setting forecasts, without the need for humans to obtain reasonable forecasts on messy data.But it is very difficult to design this thing. Let a group of undergraduates do such a thing?

"President Chen? Academician Ning Wei assigns you undergraduates such tasks?" Kong Wenjue asked subconsciously.

Chen Diancheng smiled and said: "Haha, is it difficult? Well, it is indeed a bit difficult! In fact, this design is said to be difficult, but you have to have confidence in our class Ning. What kind of person is our director Ning? Don’t you know? How strict are the requirements for Ning’s class, and what we think is difficult, does Ning also find it difficult? Take a step back and say, this is not an exam, and it’s not like you can’t find foreign aid? For Ningshe , if there is foreign aid to do this well, it is also a manifestation of strength."

Kong Wenjue nodded subconsciously, and said: "That's right, that's fine, President Chen, you can give me the title later, and I'll try to see if I can do it."

Chen Diancheng nodded slightly with a smile, then lowered his voice and said: "Then it's settled, Senior Brother Kong, as long as you make it, it will almost work, let me have face in front of Director Ning, and I will directly recommend you to join us when I turn around." The crystal shoe project team. This time I will discuss with you, and I will definitely fight for a core position for you. However, Ningshe will be re-elected in the second half of the year. We are all graduate students now. Brother Kong, you, as the backbone member of the project, can vote for me One ticket."

After hearing this, Kong Wenjue blinked, and asked in a low voice, "What? President Chen, do people in Ning Society dare to take your position? Impossible?"

Chen Diancheng lost his smile, and said angrily: "It was impossible at first? But our Director Ning accidentally said something during the meal that day, I am now a graduate student, and I have to put more energy into research. The management of the Ning Society will let it go... Some people have heard this, so they will be interested? Our director Ning is good at everything, but the management is too lenient! Hey..."

Kong Wenjue nodded quickly and said, "That's right, that's right, don't worry, President Chen, I joined the project team, and I will definitely support you in this matter!"

"Okay, let's do it for today. If your project is done well, it will fall into the eyes of our Ning Dao, and a project of Ningshe will be a p! If you are engaged in wireless communication, our senior brother will also do the next generation of frame-type three-dimensional It seems that talents in this area are needed for monitors. If you can join that project team, you will be called a top performer! It is a national scientific research project with a new chip and operating system! Easier! You can basically choose any title you want, such as outstanding youth, Yangtze River scholar, or young scientist!"

Chen Diancheng patted his chest and said.

After finishing their business, the two chatted casually about other things.

Although he was chatting all the time, he didn't forget to eat some snacks in front of him from time to time and drink a sip of coffee. Even though Wenjue didn't say much, the snacks in front of him didn't move at all...

Carefully spread the peanut butter on the last piece of waffle, stuffed it into his mouth satisfied, and drank the last sip of coffee, Chen Diancheng clapped his hands and said: "Okay, let's go here first today, and we will study it later There is still a lecture in the center that I have to attend, so let’s go first.”

"Well, President Chen, why don't we add a wechat first, and you can send me the title later? It won't be troublesome to find someone in Ningshe's group."

"Oh, I almost forgot, okay, shall I sweep you or you sweep me?"

"I'll sweep you."

"Ok!"

After adding friends, Chen Diancheng walked away contentedly. How should I put it, after sitting down for an hour, he felt that Senior Brother Kong was really funny. Brother, how can you finish it...

……

Yanbei University, True 3D Display and Imaging Smart Optics Laboratory.

This laboratory was established by Ning Wei about 20 months ago. Among them, Ning Wei took out a small goal, Huawei and Huaxin Precision jointly funded about two small goals, and Yanbei University provided the site for the construction of the laboratory.

According to the agreement signed by many parties, after the completion of the laboratory, it will be managed by the laboratory and equipment management department of Yanbei University. The only thing is that the graduate and doctoral programs led by Ning Wei have free and preferential treatment for all equipment and instruments in the laboratory. The right to use and other consumables in the experiment are borne by the students themselves, and they can purchase them by themselves, or apply to the management department for unified purchase.

At the same time, the laboratory has also formed a partnership with several laboratories in the school.Specifically, when the laboratory encounters some difficulties, the laboratory can cooperate with professors from other disciplines to carry out joint research, such as the new material laboratory, various physics laboratories, and so on.

Of course, the source of funding is mainly drawn from the project team of the Display and Imaging Optics Laboratory.

In fact, the laboratory that Ning Wei introduced into the investment and construction of strategic partners is not only for the research topics of his own students, but also for the consideration of the adaptation of new systems and new chips.

To be more specific, in order to have a common market path for independent chips and systems and to open up the market, we tried to take a differentiated competition route.This is also the route that Ning Wei has drawn up after deciding to make its own desktop-level CPU products.

As for whether it can be successful, I didn't think too much about it.Anyway, in Ning Wei's opinion, the investment is not much. If other people don't invest, it's no big deal for him to donate a laboratory to the school personally.

And according to the various industrial reference data collected so far in March, the possibility of making it is still very high.The major material laboratories in China actually have a lot of materials with outstanding performance in reserve. The only problem is that the preparation of some materials is not so easy, and there are not many ways to reduce costs for reference.

But these are not a problem.

The cost of many materials remains high. In fact, the main reason is that there are not many applications that can be used in large quantities. This also gives production units the motivation to explore how to reduce costs.Or the advantages of the material itself are as obvious as the disadvantages, and there are not many application scenarios.

If we can make some things first and open up enough markets, capital will naturally start to pay attention to the entire industrial chain, giving them enough confidence and motivation to find ways to reduce costs and release production capacity.

Of course, this is the purpose of scientific research. Every bit of progress in application also represents the rise of a certain industry.The premise is that it needs to attract enough capital attention.

At this time, Zhang Dingxi from Huaxia National Defense University is leading the juniors of the project team to conduct a data inspection of the finished product in the laboratory.

This is a new type of display technology.

There is one thing to say, it took nearly a year and a half, a core team of 18 people, and more than a dozen foreign aid experimental project teams, the final design of the engineering sample looks ugly.

How should I put it, it is a square frame made of several white vertical strips of unknown material. It is shaped like an old-fashioned crt monitor, a non-standard hexahedron with a large front and a small back, which is placed on a bracket.But it is bigger than those big monitors in the past. The front screen is 32 inches, but unlike those old-fashioned crt monitors, its screen position and the upper surface are hollow, and the hands can easily move from these two positions. Into it.

The remaining surface is closed with a translucent material.This translucent material is tightly clamped in the middle of the frame, and the workmanship is not particularly detailed, and some metal circuits can be seen in the cracks.

However, this is also the reason why the final packaging is not performed for the convenience of operation.You only need to make a few matching insulation seals in the cracks, which can not only play a role in isolating dust, but also make it more beautiful.

Standing in front of the screen, Zhang Dingxi, who was wearing a white coat, nodded to the two assistants beside him, and said, "Turn on the power, and see how things go this time."

The young assistant standing next to the test bench nodded and pressed the switch on the side of the test bench. The connecting rods around the frame lit up one by one. , green, and blue, and then the blue light and shadow gradually turned purple, until finally completely dimmed, and returned to the appearance when it was not powered on, leaving only the power indicator light directly in front of it still always on with a weak white light.

"The first overall test of the [-]D display frame has begun." Zhang Dingxi paused before speaking again: "Change the light."

The lights in the laboratory dimmed instantly, leaving only a faint yellow light.

Only then did Zhang Dingxi pick up the connection cable from the side frame of the monitor, and plug the hdmi interface from the connection cable into a square black box next to the console on the other side.

"Image test No. [-]." Zhang Dingxi nodded, ordered, and then looked nervously at the monitor.

The assistant beside him has already started to operate on the operating table, and soon the signal began to inject, and there was obvious light and shadow gathering in the box. About three seconds later, a three-dimensional dog lying in the box that looked eighty-tenths like March The three-dimensional kitten picture gradually appeared and appeared in the box.

However, Zhang Dingxi's expression changed from being clear at first to serious, and finally frowning.

Although it is said that the general outline after molding can be recognized as March, the clarity is obviously not enough. I can see the cat's face clearly, but it looks a little blurry like a nearsighted person looking at distant objects, especially the yellow and white. The position of the hair edge and the face representing the cat's whiskers are also difficult to distinguish clearly.

"The clarity is not enough, adjust the parameters..."

"Brother Zhang, the system shows that this recommendation is already the best effect."

"Okay, record all the data. Start the No. [-] touch test."

Soon, the second test will start,

The image of the kitten gradually disappeared, and this time a cube gradually appeared on the screen. There were nine small squares facing Zhang Dingxi, and the four colors were arranged in a chaotic order. There is no doubt that this time it was shaped like a Rubik's cube.

Zhang Dingxi took off his gloves, raised his right hand and stretched into the box, and put his hand under the Rubik's Cube. He held it in the void and twisted it, but the Rubik's Cube didn't move. Zhang Dingxi frowned again, and raised his hand two inches. From the effect point of view, it has already cut into the inside of the Rubik's Cube. This time it is twisting, and the Rubik's Cube finally follows the direction of Zhang Dingxi's twisting hand, and moves synchronously.

Although it looks a bit weird because the hand is inserted into the lower layer of the Rubik's Cube, the movement speed of the Rubik's Cube body is synchronized with the movement of the hand.

The assistant on the side stared at the console screen, and read out the suggestion given by the system: "The accuracy of the automatic control position judgment is not accurate, the hardware problem or the algorithm problem is to be determined, you can try to add two cameras at the lower points b23 and c46 , the sensor data is stable, and the synchronization adjustment is 99.632%"

------------

370 direction

There is no problem with the color display of the Rubik's Cube. After all, there is no need for too many details to display, and naturally there is no problem with clarity.However, when you stretch your hands into the screen to twist the Rubik's Cube, because the position recognition of the hands is not accurate, you can even feel that there is a big difference in the recognition of the horizontal or up and down positions of the two hands, so it looks particularly awkward when twisting.

When the hands are drawn out of the display frame, the overall twisting of the Rubik's Cube can be controlled remotely by waving hands very smoothly.Open the fist, the Rubik's Cube becomes larger, the palm is held empty, the Rubik's Cube becomes smaller, and the hand is turned sideways, the Rubik's Cube becomes a corner-standing mode, all smooth.

This time the test took a long time, it took 10 minutes, and finally observed the entire dynamic process of the system automatically restoring the Rubik's Cube, and after automatically recording all the data, Zhang Dingxi started the third test.

This time the display is concentrated at the bottom of the monitor. After the light converges, the overall three-dimensional image of Yanbei University "grows" from the bottom of the screen.What's more valuable is that this image can be clearly seen and is still dynamic. It is facing Zhang Dingxi's scaled-down road, and it can be seen that the car body is moving. The smaller black spots on the sidewalks on both sides are naturally pedestrians.

It is difficult to tell the direction of the densely packed teaching buildings. Fortunately, Weiming Lake and Boya Pagoda on the opposite side are used as references. Zhang Dingxi quickly found the location of the Mathematical Research Center, then clicked on the location of the Mathematical Research Center, and then used Gesture-controlled image magnification.

This time it was not as smooth as the Rubik's Cube. The picture suddenly paused for about a second, and then the colors began to blur, as if the whole picture had been mosaiced, and then it became clear little by little until Yanbei International Research Center for Mathematics The overall layout of is displayed on the display.

At this time, I can finally see the buildings clearly, but the clarity is still not very high, especially when I notice the windows and walls, I feel that some of the overall display is a little blurry.

Zhang Dingxi is a little bored. This is not a problem of graphics card or CPU computing power. The console is directly connected to the laboratory cluster, backed by a computer cluster. Naturally, it is impossible to have insufficient computing power for detail rendering in simple display. , can only be a problem with the resolution of the display itself.

But how to say, it is already very good to have this effect in the first test.

"Brother Zhang, let's build a bigger screen from now on, and use it as a sand table for battle deduction or something. It's really cool." Zhang Dingxi's assistant said, probably to ease everyone's emotions.

"Well, you can make a sand table, and you can also sell it to the real estate bosses and throw it in the sales department to replace the current model. They certainly don't mind the price of this thing. At least you don't need to open a real estate and make a set of models. A set of equipment can I have been using it all the time. In the future, as long as the three-dimensional map is made, it can be displayed directly. The size can also be made larger. If the size is doubled, the data should be substantially improved. I heard that the set of models is also the same That's hundreds of thousands!" Another assistant also commented.

This is of course reasonable. The larger the volume, the easier it is to stack various materials in it. The technology is not good enough, and hardware can be used to make up.

"Okay, needless to say these are useless. Our goal at Director Ning is to allow this display to enter thousands of households together with our own chips and systems, completely replacing traditional displays. As you said, when the time comes A monitor costs hundreds of thousands of dollars to make, and if you sell it to you at the cost price, are you willing to use it?" Zhang Dingxi said angrily.

"Hey, Brother Zhang, you can't say that. There is always a period of market adaptation for new products, and the cost will gradually come down, so you don't have to push yourself too hard!" The assistant in front of the console didn't think so. Said intentionally.

Zhang Dingxi let out a long sigh after saying this, and said, "Hey, I really want to relax, but do you want to relax? We can't even compare to a girl, can we? Xiao Li has already gone to the Huawei laboratory to be in charge of Hongmeng. The system's intelligent multi-modal sensing standardized interface signal processing has started. I heard that she will be given a burden for a while. This must be a good job. Now the documents they give us are becoming more and more comprehensive, and we can't be the last Director Ning took care of everything, but in the end we were in charge of a monitor but it was broken, right?"

Apparently the little Li that Zhang Dingxi was talking about was Li Jingwen, the only girl among their doctoral students this year.

"Hey, Brother Zhang, speaking of Senior Sister Li, I heard that she's been having trouble with her boyfriend recently!" As soon as Li Jingwen was mentioned, another assistant next to him came to the nature of gossip and added a sentence.

Zhang Dingxi turned his head and stared at him, and said in a muffled voice, "Don't meddle in other people's business."

But as soon as he finished speaking, the guy couldn't help but add: "Hey... But how do you say this thing, it's really a prophecy. When Director Ning invited us to dinner for the first time, Xiao Li I just said that the two of them can be in a long-distance relationship in both schools. Now it’s good, it’s really a long-distance relationship. But Huaqing, I understand everything. It’s miserable enough to be an undergraduate, and it’s not enough for a graduate student. If you move, you will basically be hopeless in this life."

Sure enough, China's two top universities have such magic power.

Although Zhang Dingxi did not study at Yanbei University as an undergraduate, after three years at Yanbei University, it is very slippery to lose the opposite school.

"Who said it wasn't! Haha, Brother Zhang's words reminded me of the first class meeting in my sophomore year. I was the only child in the same bed. After two years, the average grade point was 2.9. I also failed two subjects and received an academic warning from the department. Yes, and his grades were quite good, but after coming here, he suddenly likes to play games. After the guy finished the exam, our instructor was so angry that his face turned red. He pulled it out of the classroom and suggested that he think about it. The method is transferred to Huaqing next door, saying that it can contribute to the improvement of the average IQ of our two schools at the same time, haha..."

This is saying...

Zhang Dingxi was a little speechless...

Scratching his head, he said, "Okay, don't talk nonsense, continue to test, today we won't do the overflow expansion test, with this resolution, it's even worse if the overflow is [-]%! Let's talk about it when the resolution problem is solved. System testing done."

In a word, the off-track chat content was pulled back, and the test continued.

The effect of the flat display test is obviously much better than the previous three-dimensional test, and the assistant directly transfers the screen signal of the console to the new display.

The desktop of the console is displayed outside the frame, which is similar to the general LED LCD screen, at least the naked eye cannot tell the difference.But the innovation is still there. When Zhang Dingxi pushes his palm forward, the screen will also move backwards. If he waves his hand towards the screen towards his body, the screen will automatically move forward.

In addition to the plane movement, when Zhang Dingxi raises his palm and bends his palm down slowly along his wrist, the screen will follow this gesture and tilt down until the entire screen is parallel to the desktop and reversed. When operating, the screen is raised again synchronously.When the hand points to the icon on the virtual screen, there will be a corresponding reaction.

Then there is the limitation of expansion and reduction. Unlike ordinary displays, this new type of display can exceed the limit of the size of the frame itself when displayed on a flat surface. According to the system records, it can be placed at a maximum of 55 inches.Of course, there are still disadvantages. When the screen display exceeds the original physical size, it cannot respond to virtual touches.

"Record, the first test plane display is more perfect, when tilted at a certain angle, there will be more obvious chromatic aberration, and the chromatic aberration adaptation cannot perfectly match the angle adjustment. In the [-]D stereoscopic mode, there is a decrease in clarity, and the virtual touch positioning is not correct. Accuracy and other issues..."

"Also, Xiao Wu, send a copy of the data automatically recorded by the system to my mailbox, and forward a copy to Director Ning's mailbox by the way. After finishing it, I have to disassemble the machine again today..."

……

"Director Ning, the test has passed, and we can proceed to the second tape-out." At the research center, Ning Wei also received good news.

"Well, pack up the data and submit it to Ning Si, and we can go back today. By the way, tell Meng Runze to go to the director of the laboratory to get two U disks, and say that I have specially approved it. This time Prepare a copy of the simulated test data for yourself, so you can use it when you write the paper later." In the office, Ning Wei nodded and said to Zhou Zhenghao who came to report the good news to him.

"Eh?" These words made Zhou Zhenghao stunned. You must know that all the data produced by the research center are confidential. Except for a few fixed addresses, other information is not allowed to be sent out, let alone copied. .

Before they followed Ning Wei to the research center, they not only had to learn the secrecy law first, but also signed a non-disclosure agreement at least half a centimeter thick.So he really didn't expect to be able to enjoy the treatment of copying materials from the research center today.

Sure enough, the boss has spoken, and all agreements are not a problem.

"Well, Director Ning, isn't this bad?"

"There's nothing wrong with it. The data of this simulation test is not considered confidential, otherwise you wouldn't be allowed to write related papers. But according to the regulations, you can't copy it yourself. The laboratory director has a complete process. After receiving the U After the disk, there will be special data management personnel in the laboratory to copy and encrypt for you. I have submitted the application for you before, mainly some data of your respective research directions, and the contents of the two are also different.

"However, after you take it out, you should pay attention to it. Except for the data needed to write the paper, don't spread it to the outside world. We will go back to school after we get the USB drive." Ning Wei continued to explain.

Zhou Zhenghao stood at the origin and thought for a while, then subconsciously asked: "Director Ning, you shouldn't be too anxious about the big paper, right?"

Ning Wei glared at Zhou Zhenghao, and taught, "Not in a hurry? It's true to hurry up! The plan you and Xiaomeng and I have made is that it's time to defend the dissertation by October next year at the latest, and it's still not enough It takes one year and two months to prepare a big paper. By the way, I have also greeted Ningsi Lab. After the next year, you will go directly to Jiangcheng to report and adapt to the environment in advance. The person in charge of the project has more contacts. How long our own desktop-level CPU technology can be upgraded in the future depends on you.”

Hearing Director Ning's words, Zhou Zhenghao was obviously motivated, and he was still in the office, saying: "Well, Director Ning, I also hope that I can cooperate with Xiaomeng, right? Why don't you help me tell him, After he graduates, he might as well go to Ningsi with me. With Xiaomeng by my side, I feel more confident."
