Chapter 117: Request from the Professor of Communications Engineering (Subscription Request) Chen Qiyi asked: "When did you write this paper? Why do you study communication engineering when you have nothing to do?" Chen Qiyi's face was full of suspicion. Although Lu Shan said last time that he was quite interested in the 3G network and 3G mobile phones promoted in the business hall, he just bought one. Chen Qiyi doesn't believe this excuse. The School of Communications Engineering at Jiangzhou University is also one of the larger colleges. Why didn't the students of these colleges just casually write a paper without seeing the business hall promoting 3G communications? Chen Qiyi believes that there are some students in this world who are geniuses and are very good at science. But human energy is limited, and it is very good to be able to achieve certain results in one or two fields. Lu Shan has achieved great results in multiple fields in a short period of time. Chen Qiyi is a little uneasy! Chen Qiyi is not a professional and is not in a position to comment on this paper on communication base stations. He is also waiting for a reply from the professor of communication engineering. However, he also read the paper in detail and knew that it was not simple. Especially after the last paper on spring optimization, Chen Qiyi dared not neglect any of Lu Shan's papers.
Chen Qiyi received Lu Shan's paper at noon and immediately sent it to Zhou Wei, the doctoral supervisor, professor and discipline leader of the School of Communications Engineering. Chen Qiyi and Zhou Wei have a good relationship in private. Both of them like to play tennis and they would play together several times a week. Zhou Wei is a subject leader that Jiangzhou University spent a lot of energy and funds to introduce in the past few years. After obtaining his doctorate degree from Shanchuan University of Electronic Science and Technology, he conducted postdoctoral research at the National Research Institute of Maple State for three years. He originally planned to settle down in Fengma Country, but was finally invited back by Jiangzhou University with emotional and logical appeals. The doctoral students Zhou Wei is currently supervising are assisting a number of national communications companies in conducting research on 3G topics. Their goal is to obtain more 3G patents so that Xiaguo's 3G communications will have some say in the international arena and will not be controlled by others. Zhou Wei is an expert in 3G communications and has absolute right to comment on this paper. As a result, before Chen Qiyi hung up the phone, Zhou Wei asked Chen Qiyi to call the students who were writing the thesis over. This is why Chen Qiyi asked Lu Shan to come over. Lu Shan smiled and did not answer Chen Qiyi's question. Instead, he asked, "Dean Chen, our group has submitted all the assignments for the Mathematical Modeling Competition. We should have no problem winning the prize. Take a look at this paper..." Chen Qiyi said unhappily, "It's already this late, and you're still keeping us in suspense." "I can't make the decision on this paper. Professor Zhou from the School of Communications Engineering will be here soon. You can talk to him slowly." Chen Qiyi was angry inside! You, Lu Shan, have this ability, so why don’t you study mathematics well? How to engage in communications engineering. Lu Shan was good at observing people's expressions and could certainly tell what Chen Qiyi was thinking. Lu Shan thought to himself that he was also helpless! In order to obtain points stably, he had no choice. Who is willing to go through the trouble? Lu Shan quickly picked up the cup that Chen Qiyi had placed on the table, filled it with hot water from the water dispenser, and said, "I've also been studying topology recently, and I have some ideas."
"Regarding the question of whether a closed three-dimensional manifold must be homeomorphic to a three-dimensional sphere, although Perelman has made relevant proofs based on the experience of his predecessors, I think there should be a formula and mathematical expression for the unity of opposites in multiple dimensions." "Are you talking about the Poincare conjecture?" As expected, Chen Qiyi became interested as soon as Lu Shan mentioned mathematics. Lu Shan nodded quickly and began to discuss topology related issues with Chen Qiyi. Anyway, the paper written by Poincare is there, and we can just take it out at the appropriate time to shut Chen Qiyi up, so that this old man won't keep making noise. After a while, Dean Zhou Wei of the School of Communication Engineering came over under the scorching sun. Although it was already late September, the weather in Jiangzhou had already entered autumn. But the weather these days was very strange. In the last few days of September, it was getting hotter day by day. Even my roommate Huang Hao from Guangzhou cursed and said he wanted to go back to Guangzhou to escape the heat. Although it is also very hot in Guangzhou, it is windy and there are occasional heavy rains. The heat in Jiangzhou is really stuffy and dry. Even if you stand there motionless, you will be sweating in a few seconds. Lu Shan knew Zhou Wei. When he was preparing for his paper "Modeling and Algorithm Research of Wireless Communication Network Base Station Site Selection Optimization Problem", he studied several heavyweight experts and professors from the School of Communications Engineering. He also knew that Zhou Wei had done postdoctoral research in Fengma Country for several years, and had recently been working with domestic communications companies such as China Unicom and China Star Huawei on 3G communications. He is an authority and expert in the communications industry. Zhou Wei's research topic has been listed as a key topic by the state, and I heard that there is a lot of research funding. Lu Shan is very good at handling things. Knowing that the weather was hot, he did not get any boiled water for Zhou Wei, but instead brought a bottle of mineral water from the tea room. Zhou Wei didn't know Lu Shan and thought Lu Shan was a student leader who came here to do odd jobs. He gulped down a few gulps of mineral water and asked Chen Qiyi, "Where's Lu Shan?" "Teacher, it's me!" Lu Shan greeted. As soon as Chen Qiyi saw Zhou Wei's expression, he knew that it should be no problem for Lu Shan's paper to be published in Zone 2. "Freshman? Majoring in Applied Mathematics?" Zhou Wei asked. Lu Shan nodded. Zhou Wei said to Chen Qiyi, "Old Chen, why are you still a freshman? Is it because the requirements of your School of Science are too strict?" "If you don't do it, I will! Lu Shan, don't study for an undergraduate degree, jump directly to graduate school, you can follow me to do research projects, and I will pay you a salary!" Lu Shan didn't know whether to laugh or cry. Chen Qiyi quickly refused! "Let's talk business! Don't think of attacking others!" "Don't even think about the human aspect. Even if you exchange all the top students in the communications engineering department, it won't work." How could Zhou Wei not be excited! The paper Lu Shan wrote is directly related to money! China only began to roll out 2008G on a large scale in 3, but because China started 3G technology relatively late, many patents are in the hands of Westerners.
Therefore, whether companies such as Huawei and China Satellite Communications build their own base stations, or communications companies purchase base stations from overseas companies such as Nokia and Ericsson, the costs are very high. What is the significance of Lu Shan’s paper! The purpose is to calculate the optimal base station layout through models, which can reduce the number of base stations purchased and built, and greatly reduce cost expenditure. When our patented technology is still far from catching up with the West, reducing expenses is the best approach. Zhou Wei has read the paper, but the paper is just a superficial representation of the actual model. If Lu Shan's model is really useful, then this paper will definitely rewrite the promotion speed and development history of 3G in Xiaguo. Zhou Wei said: "I have read the paper. It is not a problem to publish it in Zone 2, let alone Zone 1." “But I want to see the model.” (End of this chapter)
